In the face of emergence bacteria resistant to common antibacterials and excessive accumulation free radicals that can cause several diseases, it is important look for new antioxidants. The goal this work was synthesize three chalcones derivatives by Claisen-Schmidt condensation then evaluate their antibacterial antioxidant activities. structure these 3 compounds has been determined NMR (1H 13C...

AbstractThe aim of the present study was to formulate poly (lactide-co-glycolide) (PLGA) nanoparticles loaded with 18-β-glycyrrhetinic acid (GLA) with appropriate physicochemical properties and antimicrobial activity. GLA loaded PLGA nanoparticles were prepared with different drug to polymer ratios, acetone contents and sonication times and the antibacterial activity of the developed nanopartic...

there has been special interest in the chemistry of quinolone and pyrimidine derivatives due to their diverse biological activities such as anticonvulsant, anti-malarial agents, antibacterial, antiviral, cytostatic, antithelemintic, antigenotoxic, anti-cancer agents. these compounds are also used as targeting delayed-type hypersensivity and anti-convulsant agents. as a part of our research work...
