Synthesis of isomeric, oxathiolone fused chalcones, and comparison of their activity toward various microorganisms and human cancer cells line

Abstract

Isomeric oxathiolone fused chalcones were prepared by condensation of appropriate acetylbenzo[1,3]-oxathiol-2-ones with benzaldehydes under acidic conditions. The synthesized compounds were screened for cytotoxic activity using HeLa cells, as well as for antibacterial activity against Micrococcus luteus, Staphylococcus aureus, Salmonella typhimurium, Escherichia coli, Proteus vulgaris, antifungal activity against Candida albicans, and tuberculostatic activity against Mycobacterium tuberculosis H37Rv and Mycobacterium kansasii strains. © 2007 Pharmaceutical Society of Japan.
