متن کاملBiological Evaluation of Heterocycle Moiety of Some Novel azoles Derivatives as Antibacterial and Antifungal potential Agents
Background & Objective: Azole nucleuses are very important part of antimicrobial, analgesic and anti-inflammatory drugs. The azole class of compounds is the most popular among the antibacterial and antifungal classes because of its lower toxicity, higher efficacy and a broad spectrum of activity. Today, Efforts have focused on the development of new, less toxic and more efficacious antifungal a...
متن کاملSynthesis and characterization of some new thiazolidinones containing coumarin moiety and their antimicrobial study
A series of novel thiazolidinones have been synthesized by reaction of various Schiff bases of coumarin with thioglycolic acid. The reaction of 4-hydroxy coumarin with POCl3 yielded 4chloro coumarin 2 and 4-chloro-3, 4', 3', 4"-tercoumarin 2a. Compound 2 was reacted with pphenylene diamine to yield 4-[(4-aminophenyl)amino]-2H-chromen-2-one.Various Schiff bases of coumarin were synthesized by co...
