  In attempt to find new pharmacologically active molecules, we report here the synthesis and in vitro antimicrobial activity of various 2-(1,3,4-oxadiazol-2-yl)- quinazolin-4(3H)-ones. The antimicrobial activity of title compounds were examined against two gram positive bacteria (S. aureus, S. pyogenes), two gram negative bacteria (E. coli, P. aeruginosa) and three fungi (C. albicans, A. niger, A. clavatus) using the broth microdilution method. Some derivatives baering a bromo or iodo group exhibited very good antimicrobial activity.

  The title compounds 6a−j, 2-[(6-methyl-1,3-benzothiazol-2-yl)amino]-N-[2-(substituted phenyl/furan-2-yl)-4-oxo-1,3-thiazolidin-3-yl]nicotinamides, were prepared from 2-chloropyridine-3-carboxylic acid (1) and 2-amino-6-methyl-benzothiazole (2) by known methods. All the compounds have been established by IR, 1H NMR, 13C NMR and elemental analyses. The in vitro antimicrobial screening of the compounds were carried out against two Gram positive (S. aureus, S. pyogenes), two Gram negative (E. coli, P. aeruginosa) bacteria and three fungal species (C. albicans, A. niger, A. clavatus) using the broth microdilution method. Some of the compounds are comparable with standard drugs.
