title: Synthesis and antimicrobial activity of novel quinazolone derivatives.
abstract: Three novel series of 4-oxoquinazoline derivatives were prepared and evaluated as potential antimicrobial agents. Evaluation of the antimicrobial activity of a variety of 4-substituted-1-thiosemicarbazides, 3,4-disubstituted thiazolines, and 3-substituted-5-thiazolidones reveals that the majority possess significant in vitro activity against Gram-positive organisms. Some derivatives also exhibited antifungal activity.
