Bacterial vaginosis is a vaginal infection that affects 60% of women of reproductive age worldwide. It is mainly caused by the bacterium Gardnerella vaginalis and is a factor that increases the probability of getting sexually transmitted diseases. We aimed to develop a new pharmaceutical form for the treatment of vaginal infections. We employed the solving-casting method to fabricate a polymeric film with Xanthan gum, a natural polymer produced by the bacterium Xanthomonas campestris, and metronidazole, one of the most commonly used drugs for vaginal infections. In order to characterize the film, we measured pH, dose uniformity, dissolution profile, and the percentage of swelling. Moreover, we performed a thermogravimetric analysis and scanning electron microscopy. The results demonstrated a pH suitable for vaginal application and uniform distribution of the drug in the film. Also, the formulation exhibited a high percentage of swelling and a slow release of the drug in a simulated vaginal fluid medium. All these attributes indicated that the manufactured film has ideal characteristics to be used and administered vaginally. It could be an excellent alternative to treat bacterial vaginosis and also improve user adherence.

Prosopis farcta (Banks & Sol.) J.F.Macbr. is an emerging medicinal plant containing a diverse array of phytochemicals, including protein, fat, carbohydrate, fibre, alkaloids, fatty acids, glycosides, and polyphenols, with strong antioxidant potential. However, the screening and characterization of phenolic compounds in P. farcta is limited. This study is conducted to determine the polyphenol contents and their antioxidant activity in P. farcta leaves samples via liquid chromatography-electrospray ionization quadrupole time-of-flight mass spectrometry (LC-ESI-QTOF-MS/MS) and high-performance liquid chromatography-photodiode array (HPLC-PDA). Total phenolic content (TPC), total flavonoid content (TFC), and total tannins content (TTC) were determined for polyphenol estimation. The antioxidant properties were measured by total antioxidant capacity (TAC), 2,2'-Diphenyl-2-picrylhydrazyl (DPPH), Ferric Reducing Antioxidant Power (FRAP), and 2,2"²-azinobis-(3-ethylbenzothiazoline-6-sulfonic acid) (ABTS). LC-ESI-QTOF-MS/MS was used to identify and characterize 47 phenolic compounds, which mainly included phenolic acids (13), flavonoids (28), other polyphenols (4), lignans (1), and stilbenes (1). According to HPLC-PDA quantification, chlorogenic acid (9.78 ± 2.15 mg/g dw) was the most abundant phenolic acid, while the main flavonoids included catechin (12.73 ± 1.29 mg/g dw) and kaempferol (7.93 ± 1.47 mg/g dw). The study demonstrated the significance of P. farcta as a rich source of phenolic compounds with antioxidant capacity that can be widely used in food, beverage, feed, and pharmaceutical applications.

Hyaluronic acid (HA) is one of the most attractive natural polymers employed in biomaterials with biological applications. This polysaccharide is found in different tissues of the body because it is a natural component of the extracellular matrix; furthermore, it has crucial functions in cell growth, migration, and differentiation. Since its biological characteristics, HA has been utilized for the new biomaterial's development for tissue engineering, such as hydrogels. These hydrophilic macromolecular networks have gained significant attention due to their unique properties, making them potential candidates to be applied in biomedical fields. Different mechanisms to obtain hydrogels have been described. However, the research of new non-toxic methods has been growing in recent years. In this study, we prepared a new hydrogel of HA and polyvinyl alcohol by the cost-effective technique of cross-linking by gamma irradiation. The hydrogel was elaborated for the first time and was characterized by several methods such as Fourier Transform Infrared Spectroscopy, Differential Scanning Calorimetry, Thermogravimetric Analysis, and Scanning Electron Microscopy. Likewise, we evaluated the cytotoxicity of the biomaterial and its influence on cell migration in human fibroblasts. Furthermore, we provide preliminary evidence of the wound closure effect in a cellular wound model. The novel hydrogel offers an increase of HA stability with the potential to expand the useful life of HA in its different medical applications.

Phytol (PHY) is an acyclic natural diterpene alcohol and a chlorophyll constituent that exhibits several pharmacological effects, such as anticancer, antioxidant, and antimicrobial. Here, we aimed to assess the PHY anti-inflammatory effect in vitro and in vivo, and to deepen knowledge on the possible mechanism of action. For this purpose, egg albumin (in vitro) test was performed by using acetyl salicylic acid (ASA) as a standard nonsteroidal anti-inflammatory drugs (NSAID). For in vivo test, male Wistar albino rats were treated (intraperitoneally) with 100 mg/kg of PHY and/or standard NSAIDs ASA (100 mg/kg) and diclofenac sodium (Diclo-Na, 10 mg/kg) to evaluate the combined effect of PHY in formalin-induced paw edema model. Furthermore, an in silico (CADD) study was accomplished to assess the effect of PHY against cyclooxygenase (COX)-1 and 2 enzymes, nuclear factor kappa B (NF-κB), and interleukin-1β (IL-1β). Results revealed that PHY exhibits dose-dependent anti-inflammatory effect using the egg albumin method. PHY (100 mg/kg) co-treated with ASA and/or Diclo-Na reduced paw edema better than PHY alone or NSAIDs individual groups. Computational study showed that PHY efficiently interacts with COX-1 and 2, NF-κB, and IL-1β. In conclusion, PHY exhibits anti-inflammatory activity, possibly via COX-1 and 2, NF-κB, and IL-1β dependent pathways.

To replace synthetic preservatives and expand green consumption, several essential oils have been tested in foods and food packaging due to their antimicrobial properties. This study aimed to analyze the synergistic antimicrobial action of a chitosan-gelatin based active biopolymers with the addition of essential oils (EOs). The antimicrobial agents were tested against foodborne microorganisms Staphylococcus aureus and Escherichia coli strains. The antibacterial activity of Thymus vulgaris, Ocimum basilicum, Origanum majorana, and the synergistic interactions among them were assessed according to the minimum inhibitory concentration (MIC) and minimum bactericidal concentration (MBC) using the microdilution method. Chitosan-gelatin based active biopolymers were developed, and 23% (w/w) of each essential oil and combined oils were added. The antimicrobial effect of active films was measured using the disk diffusion method. Active films with the addition of essential oils have potential applications as active packaging agents, especially those that demonstrated inhibition zones. Combined EOs can be used to enhance the antimicrobial activity, ensuring reduced doses used in active packaging and decreasing the association with adverse sensory characteristics.

There is evidence that palmatine (PA), an alkaloid isolated from the Guatteria friesiana plant, has some important biological activities, including anti-inflammatory and antidepressant effects. In this study, the antioxidant and anti-acetylcholinesterase (AChE) effects of PA were assessed. The antioxidant capacity was evaluated in vitro and in vivo through 7 distinct assays, and the anti-AChE activity was determined in vitro. The standards, trolox and ascorbic acid were used for the in vitro antioxidant test, while hydrogen peroxide was selected as a stressor for the Saccharomyces cerevisiae test. Additionally, PA was also combined with trolox and ascorbic acid to determine the likelihood of synergistic effects occurrence to what concerns to antioxidant potential. PA exhibited a potent and concentration-dependent antioxidant potential, although a stronger antioxidant activity was stated using the PA + trolox combination. PA was also found to inhibit AChE activity when compared to the negative control. Thus, PA may be viewed as a promissory phytotherapeutic agent to manage oxidative stress-mediated neurological diseases, especially the Alzheimer's and Parkinson's diseases.

Telomere length is correlated with cell proliferation, and cancer cells are characterized by an uncontrolled cell cycle. Being apoptosis one of the checks and balances incorporated into cells cycle, due to its characteristics, cancer cells are able to overcome this process. In particular, the tumour suppressor protein p53 loss or inactivation can lead to activation of telomerase enzyme, which can make cells unable to detect DNA damages that spurs apoptosis. Some bioactive compounds, in particular phenolic compounds, saponins and alkaloids have revealed good abilities to affect p53 expression and indirectly control the telomere length. In this sense, this review gives a key emphasis to the ability of these compounds in blocking cancer progression by acting on p53 expression and controlling telomere length. As main findings, phenolic compounds, saponins and alkaloids interfere with cancer progression by stimulating p53 expression, which can cause pro-apoptotic onset and restrict the anti-apoptotic activity, in addition to preventing telomerase enzyme activity.

The growing number of bacterial strains resistant to therapeutic agents has been surpassing the various antibiotics developed by the chemical and pharmaceutical industries. This problem has driven the development of research using agents with antimicrobial potential, with an emphasis on plant-derived natural products. This study evaluated the chemical compounds present in Eucalyptus citriodora essential oil (EOEc) cultivated in northeastern Brazil and its properties as an antibacterial agent and resistance modifier against methicillin-resistant Staphylococcus aureus (MRSA) and β-lactamase-producing strains. The EOEc was obtained using the hydrodistillation method, later analyzed by GC/MS, presenting a total of twelve compounds, with citronellal (65.45%); citronellol (14.87%); isopulegol (11.80%) and citronellyl acetate (2.51%) as its main constituents. The microdilution test was used to determine the minimum inhibitory concentration (MIC) and the bacterial resistance modulation of the essential oil. The EOEc did not present significant activity against the tested strains (MIC > 1000 µg mL-1). However, when evaluating the capacity of the EOEc to modify the resistance of S. aureus and E. coli strains to different antimicrobials, synergistic effects were obtained with reduced MIC values for all tested antibiotics being obtained. The EOEc showed antimicrobial and β-lactam optimizing potential against resistant strains, presenting itself as a possible alternative for the use of these drugs at concentrations lower than those indicated against resistant strains.

Gamma-aminobutyric acid (GABA) receptors belong to a ligand-gated ion channels family and are markedly expressed at the axon terminals of retinal bipolar cells. Ascorbic acid (AA), a known and vital antioxidant in the brain can modulate GABA receptors. We postulate that AA would antagonize benzodiazepines' effect via GABA receptor(s) interacting pathway. Here, we evaluated the modulatory sedative effect of AA on diazepam (DZP)'s anxiolytic effects in Swiss albino mice. The anxiolytic study was accomplished by using open-field, hole-board, and by swing and light-dark tests taking DZP as a standard anxiolytic drug. To understand the possible modulatory effects of AA, animals were co-administered with AA and DZP and/or its antagonist flumazenil (FLU). Additionally, an in-silico study was undertaken against GABA(A1), GABA(B1), and GABA(Aρ₁) receptors. Data suggest that AA at 25 mg/kg (i.p.) increased (p

Resveratrol (3,5,4'-trihydroxy-trans-stilbene) is a phytoalexin present in a variety of plant species. Resveratrol has a wide spectrum of pharmacologic properties, and it exhibits versatile biological effects on different human and animal models. The studies have shown that potassium (K) channels can be potential targets in the mechanism of resveratrol action. K channels play a crucial role in maintaining membrane potential. Inhibition of K channels causes membrane depolarization and then contraction of smooth muscles, while the activation leads to membrane hyperpolarization and subsequently, relaxation. Five diverse types of K channels have been identified in smooth muscle cells in different tissue: ATP-sensitive K channels (KATP), voltage-dependent K channels (Kv), Ca2+ - and voltage-dependent K channels (BKCa), inward rectifier K channels (Kir), and tandem two-pore K channels (K2P). The expression and activity of K channels altered in many types of diseases. Aberrant function or expression of K channels can be underlying in pathologies such as cardiac arrhythmia, diabetes mellitus, hypertension, preterm birth, preeclampsia, and various types of cancer. Modulation of K channel activity by molecular approaches and selective drug development may be a novel treatment modality for these dysfunctions in the future. The plant-derived non-toxic polyphenols, such as resveratrol, can alter K channel activity and lead to the desired outcome. This review presents the basic properties, physiological, pathophysiological functions of K channels, and pharmacological roles of resveratrol on the major types of K channels that have been determined in smooth muscle cells.

The lack of an effective anti-viral agent and the emergence of drug-resistant strains dictate a real need for discovery of novel therapies able to ameliorate viral infections. In this regards, medicinal plants and natural products offer safe and inexpensive platforms for discovery of efficient and novel anti-viral agents. We have investigated the potential anti-viral activities of Veronica persica Poir. as a medicinal plant against herpes simplex viruses (HSVs). In vitro screening of the ethanol plant extract against HSV-1 and HSV-2 infected Vero cells revealed the extract to show a dose-dependent inhibitory activity against both virus strains. After fractionation of the extract by a stepwise methanol gradient and evaluation of each fraction, the 80% methanol fraction displayed a pronounced inhibitory activity against the herpes viruses. The highest antiviral activity was observed when the Vero cells were treated with the extract both during and after infection by viruses. Moreover, the extract showed a prominent synergistic activity in combination with acyclovir anti-HSV therapy. Our findings revealed the potential of V. persica extract, especially its 80% methanol fraction, in inhibition of herpes simplex viral infections.

Leishmaniasis is a neglected parasitic protozoal disease that affects approximately 12 million people and represents a public health problem in Iran. The objectives of this study were to obtain the essential oil (EO) from Pulicaria vulgaris Gaertn. growing in Iran and to carry out in-vitro antileishmanial screening of the EO against promastigotes of Leishmania major and Leishmania infantum. The EO from the aerial parts of P. vulgaris was extracted by hydrodistillation. Serial dilutions of the EO were screened for in-vitro antileishmanial activity using 96-well microtiter plates. The P. vulgaris EO was active against the promastigote forms of L. major and L. infantum, with IC50 values of 244.70 and 233.65 µg/mL, respectively. Pulicaria vulgaris EO may serve as an alternative or complementary treatment for leishmaniasis.

Leishmania major is an intracellular parasite generally responsible for cutaneous leishmaniasis (CL), one of the most encountered skin diseases especially in Pakistan, Iran, Iraq, and Saudi Arabia. Current treatment options are not ideal, due to unwanted side effects and increasing resistance and availability is often limited in developing countries. Medicinal plants continue to attract attention because of their beneficial effects in the prevention or/and accelerating the healing process of various diseases. In this study, in vitro and in vivo susceptibility of L. major to Veronica persica Poir. extract, a medicinal plant with many applications, has been evaluated. Antileishmanial activity of plant extract was investigated both on cultured L. major promastigotes and in mice challenged with L. major. Animals were divided into three groups including control (without any treatment), test (treated with plant extract) and glucantime (the reference drug) treated groups. After treatments, skin lesion sizes and body weights of animals were checked during 4 weeks. The potential of the plant extract in decreasing the number of parasites in spleen cells of animals as well as inducing the nitric oxide (NO) production by macrophage cells was also investigated. In vitro tests showed that the plant extract was able to reduce the survival time of promastigotes in a concentration-dependent manner. In vivo experiments also revealed a significant influence of V. persica extracts on accelerating the healing process as well as reducing the overall disease burden in animal model by inducing NO production in macrophage cells. Our findings indicated the promising potential of V. persica extract as an ideal candidate in the treatment of CL caused by L. major.
