The increasing microorganism resistance to common antimicrobial drugs constitutes a major public health issue worldwide and particularly in Gabon. The objective of this study was to conduct an ethnobotanical survey among merchants of Peyrie market in Libreville (Gabon) to identify plants or a combination of plants used to treat malaria in traditional medicine. Information was collected by interviewing merchants of the market using a structured questionnaire. Plant samples were identified and authenticated at National Herbarium at the Institute of Pharmacopeia and Traditional Medicine in Libreville, Gabon. A literature review of the collected species was done. Twenty-nine (29) plants were identified, and some of them are often used in combination. Decoction, maceration, and herbal teas were the different methods of preparation. Barks, leaves, and fruits were the most plant parts used. Overall, some of these plants have already been investigated for their antimalarial properties, such as Momordica foetida (Cucurbitaceae) and Enantia chlorantha (Annonaceae). The data also highlighted several chemical compounds in the plants which can be responsible for the antiplasmodial activity described,...

Bombax ceiba L. is an important medicinal plant belonging to the family Bombacaceae. Root bark samples of the plant have been subjected to phytochemical investigation through gas chromatography-mass spectrometry (GC-MS). Twenty phytochemical compounds have been identified in the methanolic extract of B. ceiba root bark. The identification of phytochemical compounds is based on the peak area, retention time, molecular weight and molecular...

This study was aimed to evaluate the anti-diabetic activity of Ethanolic extract of the whole plant administered at different dosages (100 mg/kg and 200 mg/kg) for 21 days in Dithizone-induced diabetic rats using Glibenclamide as a standard drug (hypoglycemic drug). For the study, rats were divided into five groups of six animals each. Group, I served as control, Group II served as diabetic control received Dithizone, Group III diabetic rats were served with Glibenclamide while Group IV and V diabetic rats were received 100 mg/kg and 200 mg/kg of Ethanolic extract of Caralluma adscendens whole plant. The antidiabetic potential of the whole plant extract was undertaken in Dithizone induced hyperglycemic models by comparing biochemical parameters like blood glucose levels, OGTT and lipid profile (total cholesterol, triglycerides, LDL, and HDL), total protein and liver function tests (Total bilirubin, ASP, ALT, and AST) along with the liver antioxidant enzymes like superoxide dismutase (SOD), catalase (CAT), reduced glutathione (GSH), malondialdehyde (MDA), glycogen content and Glycogenic enzymes were quantified using standard experimental procedures. ...

The main goal of this work is to formulate nanosponges and access its suitability to deliver Luliconazole for topical application, to improve its therapeutic effect, better dispersion and good storage. Nanosponges are water-soluble, which does not mean that molecules are chemically decomposed in water but that nanosponge particles are mixed with water and used as a carrier fluid. Compared with traditional drug delivery methods, nanosponges have several advantages. Using polyvinyl alcohol as a surfactant, a nanosponge with ethyl cellulose as a polymer was prepared by the emulsion solvent diffusion method. An optimized batch of nanosponges with high entrapment efficiency was used to formulate the gel with Carbopol 940. The prepared gel was evaluated for pH value, viscosity, spreadability, in vitro diffusion study, skin irritation test and in-vitro antifungal activity. The nanosponge system is non-toxic, non-irritating, non-allergenic, and non-mutagenic. Nanosponge gel as a local drug delivery system has a huge potential, with better antifungal activity and stability. These small sponges loaded with luliconazole proved to be better scaffold for topical...

Chronic low-grade inflammation of adipose tissue is associated with obesity and insulin resistance (IR). The aim of this study is to determine the effect of troxerutin (TX) on insulin signaling in tumor necrosis factor α (TNFα) treated 3T3-L1 adipocytes. Differentiated 3T3-L1 adipocytes were pre-treated with TX, elastatinal (ELAS) or sodium salicylate (SAL) before exposure to recombinant human TNFα (20 ng/mL) for 24 h. Glucose uptake was measured by 2-[N-(7-nitrobenz-2-oxa-1, 3-diazol-4-yl) amino]-2-deoxyglucose (2-NBDG) assay. The protein expression of insulin receptor-β (IR-β), insulin receptor substrate-1 (IRS-1), phosphatidyl inositol 3 kinase (PI3K) association with IRS-1, protein kinase B (Akt) and glucose transporter 4 (GLUT4) were studied. The mRNA and protein expression of caveolin-1 and suppressor of cytokine signaling 3 (SOCS3) were also analyzed. TNFα treated 3T3-L1 adipocytes displayed decreased tyrosine phosphorylation of IR-β and IRS-1. Further, the association of p85 subunit of PI3K with IRS-1, subsequent Akt phosphorylation and GLUT4 activation were also reduced. TX pre-treatment enhanced tyrosine phosphorylation of IR-β, IRS-1, IRS1-PI3K association and Akt and GLUT4 expression. These changes were...
