A novel N-(2-Chloro-6-methylphenyl)-2-[[6-[4-(2-hydroxyethyl)-1-pipear azinyl]-2-methyl-4-pyrimidinyl] amino]-5-thiazolecarboxamide derivatives (6a-6d) and (8a-8b) were synthesized by coupling 2-[(6-chloro-2-methylpyrimidin-4ylamino]-N-(2-chloro-6-methylphenyl) thiazole-5-Carboxamide(3) with Piperazine derivatives(4,7) in butanol and DIPEA (Diisopropylethylamine) at 120ºC for 4-5hrs. All the synthesized compounds were characterized physically and elucidated by Infrared spectroscopy, Mass spectroscopy, 1H-NMR spectroscopic techniques. All the synthesized compounds were subjected to Molecular docking studies by using 2GQG as its PDB ID. Among all the compounds, 6a, 6b, 6d, 8c and 8b exhibit anticancer...

About 6 extract (methanol, acetone, hexane, ethyl acetate, hexane-ethyl acetate, aqueous extraction) from the leaves of Mangifera indica was extracted. Hexane-ethyl acetate was characterized by Gas Chromatography- Mass Spectroscopy. Ten constituents from 10 peaks were identified. Terpinyl acetate (5.80%) and phytol isomer (5.12%) are as the major constituents and the minor constituents like oxirane (3.57%), sabinene (3.24%), beta-pinen (3.34%), beta-myrcene (3.23%) , cymene (3.68%), alpha-limonene (2.82%), eucalyptol (1,8-cineo (4.71%), 1,3-benzodioxole, 5-(2-, (3.68%) were identified. The antimicrobial activity of different extract was tested against human and plant pathogenic bacteria. Hexane-ethyl acetate extract showed significant role on inhibiting almost all tested pathogenic organisms. Using histochemical reagents such as Phloroglucinol-HCl, Dragendorff reagent was used for the localization of lignin and alkaloids respectively. Mangifera indica showed 100% larvicide activity. The addition of various concentrations of hexane-ethyl acetate extract of Mangifera indica on the L929 cell lines showed cytotoxic...

Phyla nodiflora is an evergreen perennial herb found near the water bodies. It belongs to family Verbenaceae. It is commonly known as frog fruit or turkey tangle. The present investigation is the estimation of primary metabolite content in various plant parts. The investigation revealed that maximum amount of soluble sugar was found in stem, maximum amount of starch found in stems, leaves showed the maximum amount of protein, fruits showed maximum amount of lipids, ascorbic acid was found in highest amount in leaves, fruits showed maximum amount of...

Background: Among the traditionally used sex enhancement natural remedies in south eastern Nigeria, L. dulcis root is very popular because of its quick onset of action. However, its use has not been scientifically validated. This study therefore investigated the effects of its ethanol extract and fractions on sexual behavior in male albino rats. Methods: Forty-five male albino rats were randomly divided into nine groups A1 – D1, A2 –D2 and E. Animals in groups A1 – D1 received daily doses of 500mg/kg of ethanol extract and fractions (n-Hexane, Ethylacetate and Methanol) respectively while groups A2 –D2 received 1000mg/kg. Group E served as the control and receive 1ml of 10% tween 80. Equal numbers of female albino rats (45) were made receptive by hormonal treatment with estradiol benzoate (10µg/100g) and progesterone (0.5mg/100g). Sexual behavior parameters in male rats when paired with receptive females were monitored on days 1, 3 and 5. Male serum testosterone concentration was also determined. Results: At 500 and 1000mg/kg, the ethanol extract and methanol fraction of...

The aim of the study was to formulate and evaluate natural palm oil based Diclofenac sodium suppositories. The formulated natural palm oil based suppositories were compared with suppositories of water soluble bases (PEG 4000 and 6000) and lipid soluble base (cocoa butter). The in-vitro drug release rate studies were carried out by using dissolution apparatus. The in-vitro release pattern of diclofenac sodium from the formulated suppositories F1, F2, F3 and F4, were found to be 9.51% to 73.67%, 16.73 to 84.22%, 65.04 % to 87.54% and 50.76% to 83.54% after 30 min and 3 hrs respectively. The rapid in-vitro release rate was shown by F3 (Formulation with PEG 4000 as base). F3 can be used for immediate action. The in-vitro release rate of F1 (with natural palm oil base) was found to be moderate and consistent when compared with all other formulations. Natural palm oil base can be considered as a suitable base for sustained release suppositories. Natural palm oil suppository base can be used as a base for...
