Background: Oxidative stress has been implicated in the pathogenesis of several acute and chronic diseases of the heart as a result of indiscriminate exposure to cardiotoxic heavy metals. The study reported here was designed to evaluate the possible ameliorative effect of aqueous extracts from Sesamum indicum (SI) seeds on oxidative stress induced by cadmium (Cd) in Wistar rats. Materials and Methods: Daily administration of Cd (200 mg/L Cd as CdCl2) in the animals' main drinking water for 21 days led to oxidative stress. Thereafter, the ameliorative effects were assessed by measuring biochemical parameters such as extent of lipid peroxidation (LPO), lipid profile, and enzymatic and nonenzymatic antioxidants, as well as serum aminotransferase activities. Results: Treatment with SI extract elicited notable reduction in serum total cholesterol, triglyceride, and low-density lipoprotein cholesterol levels as well as concomitant increase in high-density lipoprotein cholesterol. SI extract also reversed the elevations witnessed in serum aminotransferase activities, LPO level, and ameliorated enzymatic and nonenzymatic antioxidant status in the heart of Cd-exposed rats. Conclusion: Thus, SI appears to be an attractive candidate with potential for the novel treatment of cardiotoxicity and management of oxidative stress arising from Cd exposure.

Total phenol, total flavonoid, and ameliorative potentials of aqueous leaf extract of Cnidoscolus aconitifolius in Fe2+‐induced oxidative stress in hepatic tissue and muscle glucose uptake using ex vivo models were assessed. These were carried out using standard procedures. The results revealed that the extract showed the presence of total phenol and total flavonoid, as well as free radicals scavenging abilities in a dose‐dependent manner. Also, the aqueous leaf extract of C. aconitifolius enhanced Fe2+‐induced oxidative injury in hepatic tissue by considerably reducing the concentration of lipid peroxidation, with improvement in the activities of catalase and superoxide dismutase in a dose‐dependent manner. In addition, the extract enhanced glucose uptake in psoas muscle. It can be deduced from this study that the extract might be beneficial to people with diabetes mellitus. Practical applications: Aqueous leaf extract of Cnidoscolus aconitifolius displayed the presence of total phenol and total flavonoid, as well as an increase in free radical scavenging activities in a dose‐dependent manner. The plant extract also improved Fe2+‐induced oxidative injury in hepatic tissue by decreasing lipid peroxidation concentration, improved the activities of catalase as well as superoxide dismutase, with enhancement in glucose uptake of psoas muscle in a dose‐dependent manner.

Glyphaea brevis twigs (Spreng) Monach. (GBT) are used by local herb healers to manage male sexual fertility disorders. The aim of this study was to examine the effects of G. brevis twigs on TM3 Leydig cells. GBT was extracted using methanol solvent, and Leydig cells were exposed to the respective concentrations of GBT extract (0.1, 1, 10, 100 and 1,000 μg/ml) for 24 and 72 hr respectively. Parameters evaluated include cell morphology, viability (MTT assay), mitochondrial membrane potential (TMRE dye), apoptosis (Annexin V Alexa Fluor 488 binding) and RT‐qPCR analyses of the mRNA expression. Results revealed that GBT had no cytotoxic effect on cell viability and the cell morphology. GBT also revealed a considerable elevation (p < 0.05) in fluorescence intensity, accompanied by intact mitochondria in TM3 Leydig cells. Furthermore, GBT resulted in the reduction of necrotic and apoptotic cells. The mRNA StAR was upregulated markedly with the effect prominent at 100 μg/ml. This study showed that GBT might be useful for managing male infertility ailments. [ABSTRACT FROM AUTHOR]

Due to the exceptional wide range in biochemical activities of natural plant products, Spondias mombim L. are attaining a new height because they present great prospects for drug advancement. This research was designed to analyze the pharmaceutical properties of S. mombim L. ethyl acetate fraction (SMEAF) on key enzymes relevant to erectile and cognitive dysfunction. SMEAF inhibitory activities of the specified enzymes were determined spectrophotometrically. Chemical profile of SMEAF were assessed by HPLC/MS analysis. Thereafter, molecular docking of the studied enzymes with chlorogenic acid, lutein, and zeaxanthin were carried out using PATCHDOCK. SMEAF had remarkable enzyme inhibitory effects against phosphodiesterase‐5 (PDE‐5), arginase, angiotensin I‐converting enzyme (ACE), cholinesterase, monoamine oxidase A (MAO), ecto‐5′ nucleotidase (E‐NTDase), tyrosinase, and stimulated sodium–potassium ATPase (Na+/K+‐ATPase) activities. HPLC/MS analysis revealed that phenolics and carotenoids were major components in these fraction notably, chlorogenic acid, lutein, and zeaxanthin. Our results suggested that SMEAF could be explored as phytopharmaceuticals. Practical applications: Spondias mombim L. are cooked as green vegetable with enormous medicinal value probably due to its polyphenols with potent antioxidant activity. Furthermore, the leaves could also be useful for therapeutic purposes against erectile dysfunction and central nervous system disorders. [ABSTRACT FROM AUTHOR]

This study evaluated the inhibitory effect of ethyl acetate fraction of Solanum macrocarpon L. leaves on cholinergic, monoaminergic, purinergic enzyme activities and identification of bioactive compounds. 2,2‐azino‐bis‐3‐ethylbenthiazoline‐6‐sulphonic acid (ABTS), metal ion chelating radicals scavenging activity, total phenolic and flavonoid contents were determined using standard methods. The inhibitory effects of the ethyl acetate fraction of S. macrocarpon on the specified enzymes were determined spectroscopically. Ethyl acetate fraction of S. macrocarpon showed a high ABTS radical scavenging activity and metal ion chelating radical scavenging activity. The fraction showed high contents of phenol and flavonoid. The fraction also inhibited AChE, BChE, MOA, tyrosinase, arginase, ecto‐5′ ‐nucleotidase, PDE‐5, ACE and stimulated the activity of Na+/K+‐ATPase. Bioactive compounds present in ethyl acetate fraction of S. macrocarpon leaves include kaempferol‐3‐rutinoside, rutin among others. Ethyl acetate fraction of S. macrocarpon leaves inhibited cholinergic, monoaminergic, and purinergic enzymes and had a stimulatory effect on Na+/K+‐ATPase. Practical applications: Solanum macrocarpon L. leaves are commonly consumed as vegetable. The enormous medicinal potential of the ethyl acetate fraction is invaluable as it's a probable source of polyphenols characterized with strong antioxidant activity. In addition, the leaves are used as functional foods and may play a crucial role in the management/treatment of diabetes mellitus, neurodegenerative diseases, and erectile dysfunction.

Therapies directed towards controlling hyperglycemia, the hallmark of type-2 diabetes mellitus, go a long way in managing diabetes and its related complications. Reducing glucose level through the inhibition of the relevant carbohydrate hydrolyzing enzymes is one among many routes in the management of diabetes. This study investigates the in vitro enzyme inhibitory and antioxidant properties of solvent-partitioned fractions of Spondias mombin and Mangifera indica leaves; which are used extensively in the treatment of diabetic patients locally. The leaves of S. mombin and M. indica were extracted with methanol and fractionated to obtain n-hexane (HF), ethyl acetate (EAF), n-butanol (BF), and aqueous (AF) fractions successively. The α-amylase and α-glucosidase inhibitory activities of fractions of S. mombin and M. indica leaves were investigated while the antioxidant activity of each fraction was analyzed using iron chelating and ABTS (2,2’-azino-bis(3-ethylbenzothiazoline)-6-sulphonic acid) radical scavenging assay. Our findings indicated that the ethyl acetate fraction of M. indica leaves contained a considerably higher (p < 0.05) amount of total phenolic, flavonoids, metal ion, and ABTS radical scavenging activity than the ethyl acetate fractions of S. mombin. Furthermore, the ethyl acetate fraction of M. indica had a considerably higher (p < 0.05) inhibitory effect on α-glucosidase (IC50 = 25.11 ± 0.01 μg mL−1), and α-amylase (IC50 = 24.04 ± 0.12 μg mL−1) activities than the S. mombin fraction. Hence, the inhibitory activities of S. mombin and M. indica leaves suggest that they are a potential source of orally active antidiabetic agents and could be employed to formulate new plant-based pharmaceutical and nutraceutical drugs to improve human health.

Objectives: This study investigated the potential ameliorative effects of Albizia ferruginea leaves on letrozole-induced PCOS in Wistar rats., Methods: PCOS was induced in 25 female Wistar rats by administering letrozole (1 mg/kg), followed by treatment with 100 and 250 mg/kg body weight A. ferruginea leaf methanolic extract, as well as 1 mg/kg body weight of Clomiphene citrate as standard., Results: An acute toxicity study revealed a toxic dosage of 2,000 mg/kg for the plant extract. The A. ferruginea extract exhibited potent hydroxyl radical scavenging ability. Treatment with A. ferruginea leaf extract improved the irregular estrus cycle and hormonal imbalance. Additionally, the extract administration led to decreased testosterone and increased estradiol levels when compared to the untreated PCOS rat. Furthermore, methanol extract normalizes the levels of insulin receptor substrate (IRS), type 2 17-HSD (HsD17β2), P53, 11a-hydroxylase/17,20-desmolase (CYP11a), and fat mass and obesity-associated (FTO), genes in the cervix of PCOS rats., Conclusions: Overall, A. ferruginea demonstrated beneficial properties on polycystic ovary circumstances in rats, presenting its potential as a promising treatment for PCOS., (© 2024 Walter de Gruyter GmbH, Berlin/Boston.)

This study investigated the effects of flavonoid-rich extract from Hibiscus sabdariffa L. (Malvaceae) leaves on liver damage in streptozotocin-induced diabetic rats by evaluating various biochemical parameters, including the molecular gene expressions of Nrf-2 and HO-1 as well as histological parameters. The extract was found to significantly reduce liver damage, as evidenced by lower levels of fragmented DNA and protein carbonyl concentrations. Oxidative stress markers, including malondialdehyde (MDA) level, were also significantly ( p  < 0.05) decreased, while antioxidant biomarkers, like reduced glutathione (GSH), catalase (CAT), superoxide dismutase (SOD), glutathione peroxidase (GPx), and glutathione-S-transferase (GST) were enhanced. Additionally, the extract improved the activities of key liver enzymes, including phosphatases and transaminases, and increased albumin levels. Importantly, the study demonstrated that H. sabdariffa extract effectively regulated the expression of Nrf-2 and HO-1, suggesting a significant role in mitigating liver damage. These findings highlight its potential as a therapeutic agent for liver protection in diabetic conditions., (© 2024 the author(s), published by De Gruyter, Berlin/Boston.)

The nutritional as well as beneficial effects of the Artocarpus communis seed on metabolic syndrome complications have not been studied. In this research, the aim was to investigate the nutritional composition and beneficial effects of Artocarpus communis seeds' phytoconstituents on the p53 core, fat mass and obesity-associated (FTO) protein and cytochrome P450 CYP11A1 domains. The elements and phytochemicals in the seed were determined through atomic absorption spectroscopy assay and gas chromatography-mass spectrometry (GC-MS) analysis, respectively. Also, the compounds detected were docked to the p53 core, FTO protein and cytochrome P450 CYP11A1 domains protein. Artocarpus communis seed contains sodium (7.824 ± 0.0134 ppm), magnesium (10.187 ± 0.0239 ppm) and iron (1.924 ± 0.0017), while zinc and cadmium were undetected. Phenolics and flavonoids were the most abundant phytochemicals in the seed. Phytoconstituents, such as pentadecanoic acid, hexadecanoic acid and methyl ester, possessing different therapeutic effects were identified via GC-MS analysis. In A. communis seed, 3-methyl-4-nitro-5-(1-pyrazolyl) pyrazole and phenanthrene were able to bind more peculiarly and specifically to the p53 core, FTO protein and cytochrome P450 CYP11A1 domains. One of the important processes that were hypothesized for the recovery of metabolic syndrome in affected victims is shown by the molecular dynamics analysis, which shows that the binding of these chemicals to the targeted structure stabilized the proteins. Therefore, Artocarpus communis seeds could be a new strategy for the management of metabolic syndrome.Communicated by Ramaswamy H. Sarma.

Protein tyrosine phosphatase 1B (PTP1B) has been identified as a promising drug target for the development of diabetes medications via an inhibition mechanism. Using a computational approach, this study investigates the binding mechanism of lead optimized natural compounds from Allium sativum against the human PTP1B. The molecular docking, induced-fit docking, and binding free energy calculations were analyzed using Schrödinger Suite 2021-2. MD simulation, and gene enrichment analysis was achieved via the Desmond module of Schrödinger to identify best compounds as inhibitors against PTP1B in diabetes management. The docking scores of the lead optimized compounds were good; 5280443&#95;121 from apigenin had the best binding score of -9.345 kcal/mol, followed by 5280443&#95;129 with a binding score of -9.200 kcal/mol, and 5280863&#95;177 from kaempferol had a binding score of -8.528 kcal/mol, followed by 5280863&#95;462 with a binding score of -8.338 kcal/mol. The top two lead optimized compounds, docked better than the standard PTP1B inhibitor (-7.155 kcal/mol), suggesting them as potent inhibitors than the standard PTP1B inhibitor. The outcomes of the induced-fit docking were consistent with the increased binding affinity used in the Glide computation of the five conformed poses between the derivatives (5280443&#95;121, 5280443&#95;129, 5280863&#95;177, and 5280863&#95;462) and the protein (PTP1B). Based on the binding fee energies (MM-GBSA), the lead optimized compounds from kaempferol exhibited more stability than those from apigenin. In the pharmacophore development, all the models exhibit good results across the different metrics. The best performing model with five of five matches on a 1.34 and 1.33 phase score was DDRRR&#95;1, DDRRR&#95;2, and DDDRR&#95;1. The average BEDROC value (= 160.9) was 1, while the average EF 1% value across all models was 101. There were no substantial conformational modifications during the MD simulation process, indicating that the apigenin derivatives (5280443&#95;121) was stable in the protein's active site in 100 ns. IGF1R, EGFR, INSR, PTPN1, SRC, JAK2, GRB2, BCAR1, and IRS1 are among the 11 potential targets found in the protein-protein interaction (PPI) of A. sativum against PTP1B that may be important in A. sativum' s defense against PTP1B. Sixty-four (64) pathways were found by KEGG pathway enrichment analysis to be potentially involved in the anti-PTP1B of A. sativum . Consequently, data obtained indicates the effectiveness of the in silico studies in identifying potential lead compounds in A. sativum against PTP1B target.Communicated by Ramaswamy H. Sarma.

This study examines the nutritional composition, phytochemical profiling, and antioxidant, antidiabetic, and anti-inflammatory potential of a methanolic extract of Spilanthes filicaulis leaves (MESFL) via in vitro , ex vivo , and in silico studies. In vitro antioxidant, antidiabetic, and anti-inflammatory activities were examined. In the ex vivo study, liver tissues were subjected to FeSO 4 -induced oxidative damage and treated with varying concentrations of MESFL. MESFL contains a reasonable amount of nitrogen-free extract, moisture, ash content, crude protein, and fat, with a lesser amount of crude fiber. According to GC-MS analysis, MESFL contains ten compounds, the most abundant of which are 13-octadecenal and Ar-tumerone. In this study, MESFL demonstrated anti-inflammatory activities via membrane stabilizing properties, proteinase inhibition, and inhibition of protein denaturation (IC 50 = 72.75 ± 11.06 µg/mL). MESFL also strongly inhibited both α-amylase (IC 50 = 307.02 ± 4.25 µg/mL) and α-glucosidase (IC 50 = 215.51 ± 0.47 µg/mL) activities. Our findings also showed that FeSO 4 -induced tissue damage decreased the levels of GSH, SOD, and CAT activities while increasing the levels of MDA. In contrast, treatment with MESFL helped to restore these parameters to near-normal levels, which signifies that MESFL has great potential to address complications from oxidative stress. Furthermore, the in silico interaction of the GCMS-identified phytochemicals with the active sites of α-amylase and α-glucosidase via molecular and ensembled-based docking displayed strong binding affinities of Ar-tumerone and 4-hydroxy-3-methylacetophenone to α-amylase and α-glucosidase, respectively. Taken together, the biological activities of MESFL might be a result of the effects of these secondary metabolites.Communicated by Ramaswamy H. Sarma.

This study aimed to examine the therapeutic activity of the cinnamic acid derivative KAD-7 (N'-(2,4-dichlorobenzylidene)-3-(4-methoxyphenyl) acrylohydrazide) on Fe 2+ -induced oxidative hepatic injury via experimental and computational models. In addition, the role of ATPase and ectonucleoside triphosphate diphosphohydrolase (ENTPDase) in the coordination of cellular signals is speculated upon to proffer suitable therapeutics for metabolic stress disorder upon their inhibition. While we know little about therapeutics with flexible dual inhibitors for these protein targets, this study was designed to screen KAD-7's (N'-(2,4-dichlorobenzylidene)-3-(4-methoxyphenyl) acrylohydrazide) inhibitory potential for both protein targets. We induced oxidative hepatic damage via the incubation of hepatic tissue supernatant with 0.1 mM FeSO 4 for 30 min at 37 °C. We achieved the treatment by incubating the hepatic tissues with KAD-7 under the same conditions. The catalase (CAT), glutathione (GSH), malondialdehyde (MDA), ATPase, and ENTPDase activity were all measured in the tissues. We predicted how the drug candidate would work against ATPase and ENTPDase targets using molecular methods. When hepatic injury was induced, there was a significant decrease in the levels of the GSH, CAT, and ENTPDase ( p < 0.05) activities. In contrast, we found a noticeable rise in the MDA levels and ATPase activity. KAD-7 therapy resulted in lower levels of these activities overall ( p < 0.05), as compared to the control levels. We found the compound to have a strong affinity for ATPase (-7.1 kcal/mol) and ENTPDase (-7.4 kcal/mol), and a better chemical reactivity than quercetin. It also met all drug-likeness parameters. Our study shows that KAD-7 can protect the liver from damage caused by FeSO 4 by reducing oxidative stress and purinergic actions. Our studies indicate that KAD-7 could be developed as a therapeutic option since it can flexibly inhibit both ATPase and ENTPDase.

Background: Alstonia boonei , belonging to the family Apocynaceae, is one of the best-known medicinal plants in Africa and Asia. Stem back preparations are traditionally used as muscle relaxants. This study investigated the antispasmodic properties of Alstonia boonei Stem back and its constituents., Method: The freeze-dried aqueous Stem back extract of A. boonei , as well as dichloromethane (DCM), ethyl acetate, and aqueous fractions, were evaluated for their antispasmodic effect via the ex vivo method. Two compounds were isolated from the DCM fraction using chromatographic techniques, and their antispasmodic activity was evaluated. An in silico study was conducted by evaluating the interaction of isolated compounds with human PPARgamma-LBD and human carbonic anhydrase isozyme., Results: The Stem back crude extract, DCM, ethyl acetate, and aqueous fractions showed antispasmodic activity on high-potassium-induced (K + 80 mM) contractions on isolated rat ileum with IC 50 values of 0.03 ± 0.20, 0.02 ± 0.05, 0.03 ± 0.14, and 0.90 ± 0.06 mg/mL, respectively. The isolated compounds from the DCM fraction were β-amyrin and boonein, with only boonein exhibiting antispasmodic activity on both high-potassium-induced (IC 50 = 0.09 ± 0.01 µg/mL) and spontaneous (0.29 ± 0.05 µg/mL) contractions. However, β-amyrin had a stronger interaction with the two proteins during the simulation., Conclusion: The isolated compounds boonein and β-amyrin could serve as starting materials for the development of antispasmodic drugs.

Introduction: This study aimed to investigate the chemical profile of GC-MS, antioxidant, anti-diabetic, and anti-inflammatory activities of the ethyl acetate fraction of Spilanthes filicaulis leaves (EFSFL) via experimental and computational studies. Methods: After inducing oxidative damage with FeSO 4 , we treated the tissues with different concentrations of EFSFL. An in-vitro analysis of EFSFL was carried out to determine its potential for antioxidant, anti-diabetic, and anti-inflammatory activities. We also measured the levels of CAT, SOD, GSH, and MDA. Results and discussion: EFSFL exhibited anti-inflammatory properties through membrane stabilizing properties (IC 50 = 572.79 μg/ml), proteinase inhibition (IC 50 = 319.90 μg/ml), and inhibition of protein denaturation (IC 50 = 409.88 μg/ml). Furthermore, EFSFL inhibited α-amylase (IC 50 = 169.77 μg/ml), α-glucosidase (IC 50 = 293.12 μg/ml) and DPP-IV (IC 50 = 380.94 μg/ml) activities, respectively. Our results indicated that induction of tissue damage reduced the levels of GSH, SOD, and CAT activities, and increased MDA levels. However, EFSFL treatment restores these levels to near normal. GC-MS profiling shows that EFSFL contains 13 compounds, with piperine being the most abundant. In silico interaction of the phytoconstituents using molecular and ensembled-based docking revealed strong binding tendencies of two hit compounds to DPP IV (alpha-caryophyllene and piperine with a binding affinity of -7.8 and -7.8 Kcal/mol), α-glucosidase (alpha-caryophyllene and piperine with a binding affinity of -9.6 and -8.9 Kcal/mol), and to α-amylase (piperine and Benzocycloheptano[2,3,4-I,j]isoquinoline, 4,5,6,6a-tetrahydro-1,9-dihydroxy-2,10-dimethoxy-5-methyl with a binding affinity of -7.8 and -7.9 Kcal/mol), respectively. These compounds also presented druggable properties with favorable ADMET. Conclusively, the antioxidant, antidiabetic, and anti-inflammatory activities of EFSFL could be due to the presence of secondary metabolites., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2023 Ojo, Ogunlakin, Gyebi, Ayokunle, Odugbemi, Babatunde, Ajayi-Odoko, Iyobhebhe, Ezea, Akintayo, Ayeleso, Ojo and Ojo.)

The purpose of this study was to investigate the protective effect of Beta vulgaris leaf extract (BVLE) on Fe2+-induced oxidative testicular damage via experimental and computational models. Oxidative testicular damage was induced via incubation of testicular tissue supernatant with 0.1 mM FeSO4 for 30 min at 37 °C. Treatment was achieved by incubating the testicular tissues with BVLE under the same conditions. The catalase (CAT), superoxide dismutase (SOD), glutathione (GSH), malondialdehyde (MDA), and nitric oxide (NO) levels, acetylcholinesterase (AChE), sodium-potassium adenosine triphosphatase (Na+/K + ATPase), ecto-nucleoside triphosphate diphosphohydrolase (ENTPDase), glucose-6-phosphatase (G6Pase), and fructose-1,6-bisphosphatase (F-1,6-BPase) were all measured in the tissues. We identified the bioactive compounds present using high-performance liquid chromatography (HPLC). Molecular docking and dynamic simulations were done on all identified compounds using a computational approach. The induction of testicular damage (p < 0.05) decreased the activities of GSH, SOD, CAT, and ENTPDase. In contrast, induction of testicular damage also resulted in a significant increase in MDA and NO levels and an increase in ATPase, G6Pase, and F-1,6-BPase activities. BVLE treatment (p < 0.05) reduced these levels and activities compared to control levels. An HPLC investigation revealed fifteen compounds in BVLE, with quercetin being the most abundant. The molecular docking and MDS analysis of the present study suggest that schaftoside may be an effective allosteric inhibitor of fructose 1,6-bisphosphatase based on the interacting residues and the subsequent effect on the dynamic loop conformation. These findings indicate that B. vulgaris can protect against Fe2+-induced testicular injury by suppressing oxidative stress, acetylcholinesterase, and purinergic activities while regulating carbohydrate dysmetabolism., Competing Interests: The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper, (© 2023 The Authors.)

In Nigeria, the use of microorganisms for food product modulation, development, and commercialization through biotechnological innovations remains unexplored and unaccepted. The microbiome-based sustainable innovation in the production process of Nigerian indigenous food requires a vigorous drive toward responsible consumption and production. The production process of locally fermented beverages and foods culturally varies in terms of fermentation techniques and is characterized by the distinctiveness of the microbiomes used for food and beverage production. This review was conducted to present the use of microbiome, its benefits, and utility as well as the perspectives toward and mediatory roles of biotechnology on the processing of locally fermented foods and their production in Nigeria. With the current concerns on global food insecurity, the utilization of modern molecular and genetic sciences to improve various rural food processing technologies to acceptable foreign exchange and socioeconomic scales has been gaining attention. Thus, further research on the various types of processing techniques for locally fermented foods using microbiomes in Nigeria is needed, with a focus on yield optimization using advanced techniques. This study demonstrates the adaptability of processed foods locally produced in Nigeria for the beneficial control of microbial dynamics, optimal nutrition, therapeutic, and organoleptic characteristics., Competing Interests: AUTHOR DISCLOSURE STATEMENT The authors declare no conflict of interest., (Copyright © 2023 by The Korean Society of Food Science and Nutrition.

Background: Cannabis and cannabinoids affect almost every system of the body and exert systemic effects such as alterations in memory and cognitive functions, neurotransmission impediment, as well as obstruction of endocrine and reproductive system functions. Reproduction is a complicated phenomenon that integrates biological, psychological and behavioural aspects, hence susceptible to intracellular and extracellular modulations by numerous chemicals and toxicants like cannabis., Aim: The effects of early-life exposure to cannabis on reproductive function biomarkers and genes were investigated in male and female Wistar rats in this study., Method: An initial computational analysis (molecular docking and induced fit docking) of some cannabinoids with reproductive enzymes; androgen and follicle stimulating hormone receptors was conducted. Overall, cannabichromene (CBC) had the best IFD scores and binding free energies for the two proteins studied and it interacted with notable amino acids within their active sites. Subsequently, forty (40) Wistar rats, 20 male and 20 female (24-28 days old, weighing 20-28 ± 2 g) were divided into two groups each and orally administered CBC for 21 days. Penile tissues, testes and ovaries, were collected for biochemical analysis (hormonal assays, enzyme activities, and metabolite concentrations), gene expressions, and histological evaluations., Results: Activities of arginase and phosphodiesterase-5 in the penile tissue were significantly increased, while nitric oxide and calcium levels were significantly (p < 0.05) decreased in the CBC-exposed groups relative to the control group. Semen analysis showed significantly more abnormalities and decreased concentration of spermatozoa in the CBC-exposed group compared to the control. Activities of 17β-hydroxysteroid dehydrogenase and cholesterol level were decreased in both testes and ovaries of CBC-exposed groups. Furthermore, levels of testosterone, progesterone, luteinizing, and follicle-stimulating hormones were reduced in the serum of CBC rats. Moreover, relative expressions of androgen receptor and follicle-stimulating hormone receptor genes were significantly downregulated in the CBC-exposed groups. Histological evaluations revealed lesions, tubular necrosis, and cellular congestions in both the testes and ovaries., Conclusion: This study suggests that pre-puberty exposure to cannabis modulates reproductive functions via cannabichromene inhibition of steroidogenesis, stimulation of erectile dysfunction (modulation of intermediates and enzymes of the endothelial nitric oxide synthase (eNOS) pathway in the penile tissue), and downregulation of the expressions of genes associated with reproduction., Competing Interests: The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (© 2023 The Authors.)

Infertility has been a major issue in our society for many years, and millions of couples all over the world are still experiencing it. There are several reasons for and causes of infertility in both men and women. Recent studies have shown that apoptosis, inflammation, and oxidative stress contribute immensely to infertility. The data regarding this report were obtained through a thorough review of scientific articles published in various databases, including Elsevier, Web of Science, PubMed, Scopus, and Google Scholar. Furthermore, PhD and MSc theses were also reviewed when compiling the data. Apoptosis, also known as "programmed cell death," is a natural and harmless process that occurs in human beings. Although it can become harmful if altered, Inflammation, on the other hand, is the body's reaction to detrimental stimuli caused by toxic substances or compounds, while oxidative stress is a phenomenon that results in an imbalance between the generation and aggregation of reactive oxygen species (ROS) in the cells against antioxidants. These three factors interchangeably bring about several reproductive disorders in the body, resulting in infertility. This review aims at discussing how apoptosis, inflammation, and oxidative stress play a role in human infertility., Availability of Data and Material: The datasets used and/or analyzed during the current study are available from the corresponding author upon reasonable request., Competing Interests: The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (© 2023 The Authors.)

Male infertility has become a problem worldwide, and recent research has emphasized the development of more effective therapy options. Among natural compounds, rutin has been widely studied for its potential to treat dysfunction related to male infertility, including a reduction in sperm quality, spermatogenesis disruption and structural disruption in the testis. A thorough review of scientific literature published in several databases, including Google Scholar, PubMed/MEDLINE and Scopus, was used to synthesize the present state of research on the role of rutin in male reproductive health. Rutin has been shown to possess antiapoptotic, antioxidant and anti-inflammatory activities, among others, which are crucial in the management of male infertility. Numerous investigations have shown that rutin protects against male infertility and have explored the underlying mechanisms involved. The present review, therefore, assesses the therapeutic mechanisms involved in male infertility treatment using rutin. Rutin was able to mitigate the induced oxidative stress, apoptosis, inflammation, and related physiological processes that can cause testicular dysfunction.

Cadmium is a highly neurotoxic heavy metal that disrupts membranes and causes oxidative stress in the brain. The study aimed to investigate the neuroprotective effect of gallic acid on oxidative damage in the brains of Wistar rats exposed to cadmium chloride (CdCl 2 ). Male Wistar rats were divided into four groups of five rats each. Group 1 was administered distilled water only throughout the study. Throughout the study, Group 2 received CdCl 2 alone (5 mg/kg b.w./day), Group 3 received gallic acid (20 mg/kg b.w./day), and Group 4 received CdCl 2  + gallic acid (20 mg/kg). Treatments were oral with distilled water as a vehicle. The study lasted 21 days. In the brain, the activities of cholinesterase and antioxidant enzymes were evaluated, as well as the levels of reduced glutathione, malondialdehyde, neurotransmitters, Na+/K+ ATPase, myeloperoxidase activity, nitric oxide, and interleukin-6. CdCl 2 -induced brain impairments in experimental animals and gallic acid prevents the following CdCl 2 -induced activities: inhibition of acetylcholinesterase (AChE) and butyrylcholinesterase (BChE), elevated neurotransmitters (serotonin and dopamine), decreased antioxidant enzymes (superoxide dismutase, catalase), decreased glutathione, Na+/K+ ATPases, and increased MDA and neuroinflammatory markers (myeloperoxidase (MPO), nitric oxide, and interleukin-6 in the brain of experimental rats exposed to CdCl 2 (p < 0.05). Taken together, the neuroprotective effects of gallic acid on CdCl 2 -induced toxicity in the brains of rats suggest its potent antioxidant and neurotherapeutic properties., (© 2023. The Author(s).)

Consumption of water polluted by crude oil is a major environmental problem typical in exploration areas. Numerous health complications such as high blood pressure, myocardial infarction, and other heart complications are prevalent and ravaging. These have gradually become age-defiling disease conditions that are usually maintained with lifestyle changes and diet control. The effect of dietary supplementation with 10% and 20% roasted cashew nuts (RCN) on systolic blood pressure and angiotensin converting enzyme I (ACE I) activities in mixed petroleum fraction (MPF) induced toxicity was studied in male Wistar rats through the modulation of the renin-angiotensin system. The phytochemicals in RCN were quantified using the high performance liquid chromatography (HPLC) technique. To predict likely binding affinity and stability, computational methods such as molecular docking, ADME, and molecular dynamic simulation were used. Out of the seven phytochemicals identified, rutin, gallic acid, and quercetin had the greatest quantities. Similarly, rutin had the highest binding affinities with ACE I, -10.7 kcal/mol, followed by quercetin, at -9.1 kcal/mol. During the molecular dynamics simulation, all of the identified phytochemicals demonstrated good pharmacokinetic capabilities and remained stable at their respective binding sites. Subsequent in vivo validation studies revealed that RCN was able to attenuate the effect of MPF by significantly (p < 0.05) lowering the systolic blood pressure and ACE I activity in comparison to the reference medication, atenolol. We recommend that cashew nuts be explored as dietary snacks as well as a low-cost, easily available component of supplements for the treatment of high blood pressure., Competing Interests: The authors declare no conflict of interest., (© 2022 The Authors.)

Background: Data available support that ninety percent of male infertility cases are due to low sperm counts. There is a scarcity of data on the medicinal effects of cannabis on fertility. This study evaluated testicular function and sperm quality modulation with cannabis in rats., Methodology: Twenty-five male Wistar rats were randomly grouped into five: A, B, C, and D, each group have 5 rats. A (control): 0.2 ml 2% DMSO, B (vitamin C): 90 mg/kg body weight, C, D, and E were administered: 5 mg/kg, 10 mg/kg and 20 mg/kg body weight of ethanolic leaf extract of cannabis (ELEC) respectively. The rats were sacrificed 24 h after the last day of the 60 day oral administrations. Flavonoids were the predominant phytochemical present in the extract while quercetin, kemferol, silyman and gallic acid were identified., Results: The results showed a significant improvement (p < 0.05) in sperm quality and a significant increase in the concentrations of follicle-stimulating hormone, luteinizing hormone, triglycerides, cholesterol, and total protein determination compared to the normal control. Similarly, there was a significant increase (p < 0.05) in the activities of acid phosphatase, alkaline phosphatase, and superoxide dismutase compared to the normal control. RAC-alpha serine/threonine-protein kinase (AKT1)-silymarin complexes (-8.30 kcal/mol) and androgen receptor (AR)-quercetin complexes (9.20 kcal/mol) had the highest affinity., Conclusion: The antioxidant effects of the flavonoids in the ethanolic extract of cannabis may have protected testicular and sperm cells from oxidative damage. Biochemical processes and histopathological morphology were preserved by cannabis. The docking prediction suggests that the bioactive principle of cannabis may activate the androgenic receptors. The androgenic receptor modulation may be attributed to silymarin and quercetin., (© 2022. The Author(s).)

Breast cancer (BC) is one of the most common and recurring diseases and the second leading cause of death in women. Despite prevention, diagnostics, and therapeutic options such as radiation therapy and chemotherapy, the number of occurrences increases every year. Therefore, novel therapeutic drugs targeting specifically different checkpoints should be developed against breast cancer. Among drugs that can be developed to treat breast cancer, natural products, such as plant-derived compounds, showed significant anti-breast cancer properties. These substances belong to different chemical classes such as flavonoids, terpenoids, phenolic acids, and alkaloids. They exert their in vitro and in vivo cytotoxic activities against breast cancer cell lines via different mechanisms, including the inhibition of extrinsic and intrinsic apoptotic pathways, the arrest of the cell cycle, and the activation of autophagy. Moreover, they also exhibit anti-angiogenesis and antimetastatic action. Moreover, chemoprevention effects of these bioactive compounds were signaled only for certain drugs. Therefore, the aim of this review is to highlight the pharmacological actions of medicinal plants and their bioactive compounds on breast cancer. Moreover, the role of these substances in breast cancer chemoprevention was also discussed., (© 2021.

The treatment of diabetes involves the use of herbal plants, attracting interest in their cost-effectiveness and efficacy. An aqueous extract of Persea americana seeds (AEPAS) was explored in this study as a possible therapeutic agent in rats with diabetes mellitus. The induction of diabetes in the rats was achieved by injecting 65 mg/kg body weight (BWt) of alloxan along with 5% glucose. This study was conducted using thirty-six (36) male Wistar rats. The animals were divided into 6 equal groups, (n = 6) and treated for 14 days. In vitro assays for total flavonoid, phenols, FRAP, DPPH, NO, α-amylase, and α-glucosidase, were performed. Biochemical indices fasting blood sugar (FBS), BWt, serum insulin, liver hexokinase, G6P, FBP, liver glycogen, IL-6, TNF-α, and NF-ĸB in the serum, were investigated as well as the mRNA expressions of PCNA, Bcl2, PI3K/Akt in the liver and pancreas. The in vitro analyses showed the potency of AEPAS against free radicals and its enzyme inhibitory potential as compared with the positive controls. AEPAS showed a marked decrease in alloxan-induced increases in FBG, TG, LDL-c, G6P, F-1, 6-BP, MDA, IL-6, TNF-α, and NF-ĸB and increased alloxan-induced decreases in liver glycogen, hexokinase, and HDL-c. The diabetic control group exhibited pancreatic dysfunction as evidenced by a reduction in serum insulin, HOMA-β, expressions of PI3K/AKT, Bcl-2, and PCNA combined with an elevation in HOMA-IR. The HPLC revealed luteolin and myricetin to be the phytochemicals that were present in the highest concentration in AEPAS. The outcome of this research showed that the administration of AEPAS can promote the activation of the PI3K/AkT pathway and the inhibition of β-cell death, which may be the primary mechanism by which AEPAS promotes insulin sensitivity and regulates glycolipid metabolism., (© 2022.

Vascularization is fundamental to the growth and spread of tumor cells to distant sites. As a consequence, angiogenesis, the sprouting of new blood vessels from existing ones, is a characteristic trait of cancer. In 1971, Judah Folkman postulated that tumour growth is angiogenesis dependent and that by cutting off blood supply, a neoplastic lesion could be potentially starved into remission. Decades of research have been devoted to understanding the role that vascular endothelial growth factor (VEGF) plays in tumor angiogenesis, and it has been identified as a significant pro-angiogenic factor that is frequently overexpressed within a tumor mass. Today, anti-VEGF drugs such as Sunitinib, Sorafenib, Axitinib, Tanibirumab, and Ramucirumab have been approved for the treatment of advanced and metastatic cancers. However, anti-angiogenic therapy has turned out to be more complex than originally thought. The failure of this therapeutic option calls for a reevaluation of VEGF as the major target in anti-angiogenic cancer therapy. The call for reassessment is based on two rationales: first, tumour blood vessels are abnormal, disorganized, and leaky; this not only prevents optimal drug delivery but it also promotes hypoxia and metastasis; secondly, tumour growth or regrowth might be blood vessel dependent and not angiogenesis dependent as tumour cells can acquire blood vessels via non-angiogenic mechanisms. Therefore, a critical assessment of VEGF, VEGFRs, and their inhibitors could glean newer options such as repurposing anti-VEGF drugs as vascular normalizing agents to enhance drug delivery of immune checkpoint inhibitors., (Copyright © 2022.

Acetylcholinesterase (AChE) has been an effective target for insecticide development which is a very important aspect of the global fight against insect-borne diseases. The drastic reduction in the sensitivity of insects to AChE-targeting insecticides like organophosphates and carbamates have increased the need for insecticides of natural origin. In this study, we used Drosophila melanogaster as a model to investigate the insecticidal and AChE inhibitory potentials of Cymbopogon citratus and its bioactive compounds. Flies were exposed to 100 and 200 mg/mL C . citratus leaf extract for a 3-h survival assay followed by 45 min exposure for negative geotaxis and biochemical assays. Molecular docking analysis of 45 bioactive compounds of the plant was conducted against Drosophila melanogaster AChE (DmAChE). Exposure to C. citratus significantly reduced the survival rate of flies throughout the exposure period and this was accompanied by a significant decrease in percentage negative geotaxis, AChE activity, catalase activity, total thiol level and a significant increase in glutathione-S-transferase (GST) activity. The bioactive compounds of C. citratus showed varying levels of binding affinities for the enzyme. (+)-Cymbodiacetal scored highest (-9.407 kcal/mol) followed by proximadiol (-8.253 kcal/mol), geranylacetone (-8.177 kcal/mol), and rutin (-8.148 kcal/mol). The four compounds occupied the same binding pocket and interacted with important active site amino acid residues as the co-crystallized ligand (1qon). These compounds could be responsible for the insecticidal and AChE inhibitory potentials of C. citratus and they could be further explored in the development of AChE-targeting insecticides., Competing Interests: The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (© 2021 Published by Elsevier B.V.)

Background: Gongronema latifolium leaf is used traditionally to treat diabetes and other diseases. The present study aimed to provide the modulatory effect of G. latifolium on hyperglycemia, inhibitory effect of redox imbalance and inflammation in alloxan-induced nephropathy in Wistar rats., Methods: Alloxan monohydrate was used to induce diabetes by an intraperitoneal injection of (150 mg/kg). Three diabetic groups were administered aqueous leaf extract of G. latifolium at 6.36, 12.72 and 25.44 mg/kg bodyweight (BW) respectively; a group was administered with metformin (5 mg/kg BW), while the other two were served as positive and negative control. Thereafter, fasting blood glucose, antioxidant enzymes, malondialdehyde (MDA) level, interleukin 2 and 6 were determined., Results: G. latifolium leaf significantly ( p  < 0.05) reduced the alloxan-induced increases in blood glucose, MDA, interleukin 2 and interleukin 6 level and increased the alloxan-induced decreases in superoxide dismutase, catalase, glutathione peroxidase, glutathione reduced and glutathione transferase activity. All these changes compared with those of metformin-treated diabetic rats., Conclusion: The data from this study suggest that G. latifolium modulates glucose homeostasis as well as inhibiting redox imbalance and inflammation in diabetic rats, which may be attributed to the effects of its phytochemical constituents such as saponins, flavonoids and alkaloids. It also indicated that inhibition of inflammatory cytokines and redox imbalance are likely mechanisms by which G. latifolium leaf exert its antidiabetic action., Competing Interests: Conflict of interestAuthors declare no conflict of interest all through the compilation of this manuscript., (© Springer Nature Switzerland AG 2020.)

Objective: This study investigated the ameliorative potential of Zingiber officinale Roscoe extract against lead-induced brain damage in rats., Methods: Thirty male rats were divided into 5 groups of 6 rats each. Lead-acetate toxicity was induced by intraperitoneal injection (10 mg/kg body weight (b.w.)) in Groups B-E. Group A (control) and Group B (lead-acetate) were left untreated; vitamin C (200 mg/kg b.w.) was administered to Group C; ethyl acetate fraction from Z. officinale extract (200 and 100 mg/kg b.w.) was administered to Group D and E by oral gavage once daily for 7 days. Changes in the content of some key marker enzymes such as acetylcholinesterase (AChE), butyrylcholinesterase (BChE), monoamine oxidase (MAO), epinephrine, dopamine, Na + /K + -ATPase, catalase (CAT), superoxide dismutase (SOD) and glutathione peroxidase (GPx) as well as malonaldehyde (MDA) levels were determined in serum., Results: Exposure to lead acetate resulted in a significant decrease (P < 0.05) in the activities of BChE, AChE, Na + /K + -ATPase, SOD, CAT and GPx with a corresponding increase in the levels of MDA, xanthine oxidase, epinephrine, dopamine and MAO relative to the control group. Levels of all disrupted parameters were alleviated by co-administration of Z. officinale fraction and by the standard drug, vitamin C., Conclusion: These results suggest that ethyl acetate fraction of Z. officinale extract attenuates lead-induced brain damage and might have therapeutic potential as a supplement that can be applied in lead poisoning., (Copyright © 2019 Shanghai Changhai Hospital.

Tithonia diversifolia (Hemsl.) A. Gray leaves have long been used to manage neurodegenerative diseases without scientific basis. This study characterized the phenolic constituents, evaluated the antioxidant properties of phenolic extracts from T. diversifolia leaves used as traditional medicine in Africa and its inhibition of key enzymes linked to Alzheimer's disease. The extract was rich in phenolic acids (gallic acid, chlorogenic acid, caffeic acid and p -coumaric acid) and flavonoids (apigenin) and had 1,1-diphenyl-2-picryl-hydrazil radical scavenging abilities (IC 50  = 41.05 μg. mL -1 ), 2,2-Azino-bis3-ethylbenthiazoline-6sulphonic acid radical scavenging ability (IC 50  = 33.51 μg. mL -1 ), iron chelation (IC 50  = 38.50 μg. mL -1 ), reducing power (Fe 3+ - Fe 2+ ) (7.34 AAEmg/100 g), inhibited acetylcholinesterase (IC 50  = 39.27 μg mL -1 ) and butyrylcholinesterase (IC 50  = 35.01 μg mL -1 ) activities. These results reveal the leaf as a rich source of phenolic compounds with antioxidant and cholinesterase inhibitory activity.

In Africa, the fruit, leaf, seed and roots of Carica papaya Linn. are generally used to treat a variety of diseases such as malaria, cancer, and cardiovascular diseases. In this study, we evaluated the protective potentials of aqueous extract of C. papaya roots on arsenic-induced biochemical and genotoxic effects in Wistar rats. Rats were induced intraperitoneal with sodium arsenate (dissolved in distilled water at 3 mg/kg body weight) for 21 days and the animals were administered simultaneously with 200 mg/kg body weight vitamin C, 100 and 150 mg/kg body weight of the C. papaya Linn. root aqueous extract once daily for three weeks. Results obtained reveals that activities of plasma 8-OHdG, serum lipids concentration, atherogenic index (AI), coronary artery index (CRI), aspartate transaminase, alanine transaminase, alkaline phosphatase, total bilirubin levels were elevated significantly ( p  < 0.05) and catalase, glutathione peroxidase, superoxide dismutase, plasma hematological profile were progressively reduced ( p  < 0.05) in arsenic-alone exposed rats. Significant increase in the quantity of chromosomal aberrations (CA), micronuclei (MN) frequency, oxidative damages in the bone marrow cells from arsenic alone rats was observed. Though, mitotic index scores in these cells were progressively reduced (p < 0.05). In animals administered with aqueous extract of C. papaya roots and vitamin C, the altered parameters were significantly recovered towards the levels observed in normal control rats. These results suggest that aqueous C. papaya roots preparations might have therapeutic potential as a supplement that can be applied in arsenic poisoning.

This study seeks to investigate the possible protective role of the methanol extract of Piper guineense seeds against CCl₄-induced hepatotoxicity in an animal model. Hepatotoxicity was induced by administering oral doses of CCl₄ (1.2 g/kg bw) three times a week for three weeks. Group 1 (Control) and Group 2 (CCl₄) were left untreated; Piper guineense (PG; 400 mg/kg bw) was administered to Group 3 (T₁) by oral gavage for 14 days prior to the administration of CCl₄ and simultaneously with CCl₄; PG (400 mg/kg bw) was administered simultaneously with CCl₄ in Group 4 (T₂); and Livolin forte (20 mg/kg bw) was administered simultaneously with CCl₄ in Group 5 (T₃), the standard drug group. The administration of CCl₄ induces histopathological alteration in the liver, with concomitant increased activities of serum hepatic marker enzymes associated with increased levels of lipid peroxidation. Similarly, there was decrease in non-enzymatic (reduced glutathione) and enzymatic antioxidants (glutathione S-transferase), superoxide dismutase, and catalase. An elevation in serum triglyceride and total cholesterol levels was noticed along with decreased levels of serum total protein. Treatment with PG 400 mg/kg bw exhibited excellent modulatory activity with respect to the different parameters studied by reversing all the above-mentioned biochemical changes significantly in the experimental animals. These results suggest that PG offered protection comparable to that of Livolin forte with better efficacy when pre-treated with 400 mg/kg bw 14 days prior to CCl₄-exposure., Competing Interests: The authors declare no conflicts of interest.

Cadmium has been considered a risk factor for humans as it accumulates in body tissues, such as the liver, lungs, kidneys, bones, and reproductive organs. The aim of the present study was to evaluate the effect of Irvingia gabonensis (IG) against cadmium (Cd)-induced nephrotoxicity. The study was performed on twenty (20) male rats divided into four groups: control group, cadmium group (4 mg/kg/day, intraperitoneally), cadmium + extract (200 mg/kg body weight by oral gavage) and cadmium + extract (400 mg/kg body weight by oral gavage). Changes in the kidney biochemical markers, namely glutathione (GSH), superoxide dismutase (SOD), catalase (CAT), aminotransferase (ALT), aspartate aminotransferase (AST) activities and levels of malondialdehyde (MDA), urea, and creatinine were determined in serum. Histological examinations were monitored. Exposure to Cd lowered the activities of kidney antioxidants, while it increased LPO levels. Levels of all disrupted parameters were alleviated by co-administration of IG extract. The malondialdehyde concentration of the rats treated with 200 and 400 mg/kg body weight of the extract significantly decreased (p<0.05) compared with the untreated cadmium rats. Yet the creatinine concentration decreased significantly (p<0.05) when the cadmium animals treated with 200 and 400 mg/kg body weight of the extract were compared with the cadmium control. Furthermore, histological alterations in the kidney were observed in cadmium untreated rats and these were ameliorated in cadmium treated rats by co-administration of IG extract. IG showed apparent protective and curative effect on Cd-induced nephrotoxicity.
