Neptunia oleracea also known as water mimosa is widely consumed by people worldwide including Malaysia. This plant was claimed able to treat several diseases such as epileptic convulsion, syphilis, jaundice, and bloody diarrhea. Moreover, it has been reported to possess antimicrobial, antioxidant, and anti-ulcer properties that benefit human health. Hence, this study investigates the content of macronutrients, micronutrients, phytochemical constituents, total phenolic content (TPC), total flavonoid content (TFC), and antioxidant properties in the aqueous leaf extract of this plant. The study found that N. oleracea leaves were possessed with high fiber (52%), moisture (23.33%), fat (5.33%), protein (5.25%), carbohydrate (6.42%), ash (7.67%), and mineral content with a sequence of Potassium > Calcium > Sodium > Phosphorus. A positive result of tannins, steroids, phenols, and flavonoids were detected. High values of TPC and TFC which were 136.19 ± 0.62 mg GAE/g and 829.17 ± 19.09 mg GAE/g of dry weight respectively were obtained. Meanwhile, the hydrogen peroxide scavenging activity of the plant extract produced an IC50 of 70.09 µg/mL. The presence of a high content of polyphenolic compounds may reflect the antioxidant properties of this plant. In conclusion, the aqueous extract of N. oleracea leaves showed the presence of various phytochemical constituents and has a high content of TPC and TFC which may be derived from its nutritional content. Hence, consumption of N. oleracea leaves is useful for human health and disease prevention. [ABSTRACT FROM AUTHOR]

Simple Summary: Luteolin is a natural compound from plants with various medicinal benefits, including anti-cancer activities. However, luteolin has limited use clinically due to its low solubility and absorption into the body. Hence, the objective of this research work was to formulate and optimize a luteolin nanomicelle formulation with improved solubility. The nanomicelle was prepared using D-α-tocopheryl polyethylene glycol 100 succinate (TPGS) and poloxamer (Pol). The solubility of Lut-loaded micelles increased up to 459-fold compared to pure Lut in water. The release study showed that Lut-loaded micelles exhibited sustained release behavior. The effects of copolymers, hydration temperature and duration, and freezing temperature were studied to find out the optimum formulation of a luteolin–micelle complex. This study has demonstrated that several factors need to be considered when developing such nanoparticles in order to obtain a well-optimized micelle. The formulation has potential to be utilized in cancer therapy. Background: Luteolin is a flavonoid compound that has been widely studied for its various anti-cancer properties and sensitization to multidrug-resistant cells. However, the limited solubility and bioavailability of Lut hindered its potential clinical use. Theoretically, the combination of this compound with vitamin E TPGS and poloxamer 407 can produce a synergistic effect to enhance tumor apoptosis and P-glycoprotein inhibition. This study aimed to develop and optimize vitamin E TPGS/Poloxamer 407 micelles loaded with luteolin through investigating certain factors that can affect the encapsulation efficiency and particle size of the micelle. Methods: A micelle was prepared using the film hydration method, and the micellar solution was lyophilized. The cake formed was analyzed. The factors investigated include the concentrations of the surfactants, ratio of vitamin E TPGS/Poloxamer 407, temperature of the hydrating solution, duration of hydration, and freezing temperature before lyophilization. The effects of these factors on the encapsulation efficiency and particle size of the micelle were also studied. The encapsulation efficiency was measured using a UV-Vis spectrophotometer, while particle size was measured using dynamic light scattering. Results: The optimized micelle was found to have 90% encapsulation efficiency with a particle size of less than 40 nm, which was achieved using a 10% concentration of surfactants at a vitamin E TPGS/Poloxamer 407 ratio of 3:1. The optimized temperature for hydrating the micellar film was 40 °C, the optimized mixing time was 1 h, and the optimized freezing temperature was −80 °C. The solubility of the luteolin-loaded micelles increased 459-fold compared to pure Lut in water. The critical micelle concentration of the vitamin E TPGS/Poloxamer 407 micelle was 0.001 mg/mL, and the release study showed that luteolin-loaded micelles exhibited sustained release behavior. The release of luteolin from a micelle was found to be higher in pH 6.8 compared to pH 7.4, which signified that luteolin could be accumulated more in a tumor microenvironment compared to blood. Conclusion: This study demonstrated that several factors need to be considered when developing such nanoparticles in order to obtain a well-optimized micelle. [ABSTRACT FROM AUTHOR]

- Abstract
Hydrogels are defined as 3D crosslinked polymer networks that can absorb and hold large volumes of water when in contact with pus filled wounds. The addition of crosslinks between polymer strands offer a better physical characteristics and provide controlled release of active ingredients at the wound sites. The objective of this study is to develop and characterize carboxymethyl cellulose (CMC) and sodium alginate (SA) cross-linked with calcium chloride loaded with octenidine (OCT) based hydrogel as wound dressing material. Crosslinked (CL) SA based hydrogel shows better swelling degree indicating that it is suitable to use in moist wound healing. CL CMC based hydrogel shows better water retention capacity implying its suitability to preserve water and maintain moist wound environment. Both loaded CL SA and CMC hydrogels showed good water retention capacity but at the same time they showed rapid fluid uptake which may increase the rapid release of active ingredient and dryness that could adversely affect the healing of moist wound. Hence, they require some modificationsso that the use of OCT in hydrogel can open up a new, non-resistant medicated wound dressing application. This study showed that both CL SA and CMC hydrogels possess potential over the NCL hydrogels as enhanced wound dressing materials. Stability studies revealed that the shelf life of the hydrogel is 30 days when kept at 5 ± 2 ◦C. [ABSTRACT FROM AUTHOR]

Introduction: The most common variety of lung cancer is non-small cell lung cancer (NSCLC) accounting for 84% of new cases. Surgery, chemotherapy and radiation are the primary treatment option. Metformin has recently been demonstrated to have an anti-tumour impact on various cancer cells. The goal of this investigation was to determine the growth inhibitory, antiproliferative, cytotoxic, apoptotic and cell cycle arrest properties of metformin HCl oral tablets on the A549 lung carcinoma cell line. Methods: The cells were treated with different dosages of an oral preparation of metformin, with untreated cells used as a control. The Trypan Blue Exclusion Assay was used to determine metformin's inhibitory and cytotoxic effects. Flow cytometry was used to evaluate apoptosis and cell cycle arrest. Results: In a dose-dependent manner, metformin HCl was able to reduce the viability of treated cells compared to the untreated control. Cell proliferation was considerably inhibited in the treated group with the IC50 dose than in the untreated control group and the IC50 dose showed no cytotoxic effect on L929 cells. Induction of apoptosis and cell cycle arrest was observed in the IC50 dose-treated group by Flow cytometry analysis and data showed metformin oral drug causes early apoptosis and a considerable cell increase in the S phase of the cell cycle. Conclusion: Metformin inhibits cell growth and induces apoptosis and cell cycle arrest in the cell line. A comprehensive proteome examination is required to understand more about the mechanism of action of the oral metformin HCl on cancer cells. [ABSTRACT FROM AUTHOR]

Mitragynine (MG) is the major active alkaloid found in Mitragyna speciosa Korth. In the present study, we investigated the enhancement of analgesic action of MG when combined with morphine and the effect of the combination on the development of tolerance towards morphine. Mice were administered intraperitoneally with a dose of MG (15 and 25 mg/kg b.wt) combined with morphine (5 mg/kg b.wt) respectively for 9 days. The antinociceptive effect was evaluated by a hot plate test. The protein expression of cyclic adenosine monophosphate (cAMP) and cAMP response element binding (CREB) was analyzed by immunoblot. Toxicological parameters especially liver and kidney function tests were assessed after the combination treatment with MG and morphine. The concurrent administration of MG and morphine showed significant (p < 0.05) increase in latency time when compared to morphine alone group and the outstanding analgesic effects in the combination regimens were maintained until day 9. For the protein expression, there was a significant increment of cAMP and CREB levels (p < 0.05) in group treated with 5 mg/kg morphine but there was no significant change of these protein expressions when MG was combined with morphine. There was a significant changes in toxicological parameters of various treated groups. The combination treatment of MG and morphine effectively reduce the tolerance due to the chronic administration of morphine. [ABSTRACT FROM AUTHOR]

Luteolin is a widely studied flavonoid recognized for its ability to sensitize multidrug-resistant cells and anti-cancer properties. However, its clinical applications is hindered by challenges arising from its limited solubility and bioavailability. To address this issue, a synergistic approach combiningluteolin with vitamin E TPGS (TPGS) and poloxamer (Pol) was explored to boost tumour apoptosis and suppress P-glycoprotein. This study aimed to optimize luteolin-loaded TPGS/Pol micelles developed using the film hydration method, followed by lyophilization. Various key factors including the drug: polymer ratio and the TPGS: Pol ratio were examined, with encapsulation efficiency (EE) assessed using a UV-Vis spectrophotometer and particle size measured via dynamic light scattering (DLS). The results revealed that the optimized micelle composed of 1:5 drug: polymer ratio and a TPGS: Pol ratio of 3:1, exhibited a particle size below 40 nm, along with EE of 90%. Additionally, there was a notable increase of 459-fold in the solubility of luteolin-loaded micelle in comparison to pure luteolin in water. The TPGS/Pol micelles demonstrated a critical micelle concentration (CMC) of 0.0008 mg/ml, and release studies indicated sustained release behaviour for luteolin loaded micelles. In conclusion, this study has presented the feasibility of TPGS/Pol micelles in improving the therapeutic potential of luteolin, showcasing improvements in EE, particle size, solubility and sustained release behaviour.

Introduction: Punica granatum is a fruit-bearing deciduous shrub or a small tree belonging to the family of L. Punicaceae. Pharmacological activities of P. granatum include antioxidant, anticarcinogenic, and anti-inflammatory properties. The purpose of this study is to investigate the antioxidant and anti-inflammatory properties of P. granatum methanolic extract (PGME) in the BV2 microglial cell line. Method: The bioactive component from P. granatum peel was extracted by a standard methanolic extraction protocol. The antioxidant properties of PGME were analyzed by total phenolic content (TPC) assay, 1,1-dipheyl-2-pycrylhydrazyl (DPPH) free radical scavenging assay, and Ferric Reducing Antioxidant Power (FRAP). The cytotoxicity activity of PGME on BV2 cells was determined by a viability test using MTS reagent. Analyses of the production of inflammatory mediators, including nitric oxide (NO) and cytokines (tumor necrosis factor-alpha [TNF-α], Interleukin [IL]-6 and monocyte chemoattractant protein [MCP]-1) have been carried out to evaluate the anti-inflammatory activity of PGME in LPS-stimulated BV2 cell line. Result: The TPC and radical scavenging activity of PGME increased in a concentration-dependent manner. However, the ferric reducing ability of PGME was slightly lower and no significant difference compared to the reference standard. PGME treatment on the LPS-stimulated BV2 cells significantly inhibits the production of NO and TNF-α and slightly reduced IL-6 level. Conclusion: PGME possesses antioxidative and anti-inflammatory properties. The PGME demonstrated anti-inflammatory activity through inhibition of pro-inflammatory immune mediators on the BV2 microglial cell line. Therefore, we suggest that PGME potentially inhibits oxidative and inflammatory processes. [ABSTRACT FROM AUTHOR]

- Abstract
Geriatric patients have difficulty to comply to their medication regimen due to complicated medication administration schedule, dysphagia, reduced ability to swallow tablets and dementia. This is particularly more challenging among the Alzheimer Disease's patients. Therefore, a model drug, memantine hydrochloride has been formulated into an orally disintegrating film (ODF) for easier consumption. However, bitter taste of memantine hydrochloride needs to be solved first if the drug is formulated into an ODF. The objective of this study is to taste mask memantine hydrochloride ODF and conduct a palatability study to evaluate the palatability of the dosage form. Memantine hydrochloride ODF was prepared using solvent casting method followed by freeze drying. The polymeric base consisted of Guar gum, PEG 400 and wheat starch in solvent water, with varying amounts of Aspartame or Acesulfame K for taste masking. The freeze-dried memantine hydrochloride ODFs were evaluated for tensile strength, in-vitro disintegration time, average thickness, dissolution, memantine hydrochloride content, and palatability. Formulation M7 was selected as the best taste masked formulation. Aspartame 30 mg is sufficient to cover the bitter taste of memantine hydrochloride in ODF form. A taste masked memantine hydrochloride ODF of dimensions 20 x 20 mm containing 30mg of aspartame was successfully developed. This formulation has average values for tensile strength 0.03 (0.01) kPa, folding endurance 351.92 (4.82) flips, thickness 0.94 (0.02) mm, and disintegration time 34.15 (2.16) seconds., (Copyright© by International Journal of Pharmaceutical Compounding, Inc.)
