Abstract
Discovery towards the potent antimicrobial agents is indispensable for the treatment of infections caused by resistant microbes. Thus, we prepared a novel series of 3-substituted 5-phenylindeno-thiazolopyrimidinone derivatives following conventional method. All the molecules were investigated for their in vitro antimicrobial potency against different bacteria and fungi, and the results were compared with streptomycin and clotrimazole standard drugs, respectively. Among the twelve analogs, 4-methoxyphenyl-5-phenylindeno[1,2-d]thiazolo[3,2-a]pyrimidin-6(5H)-one showed equipotent activity against a bacterium, Staphylococcus aureus (minimum inhibitory concentration 25 µg/mL and zone of inhibition 22 mm), and a fungus, Aspergillus niger (zone of inhibition 20 mm). The rest of the thiazolo[3,2-a]pyrimidin-6(5H)-one derivatives exhibited week to reasonable activities against the tested bacterial and fungal strains.
