Abstract

Condensation of 1-amino-4-benzylidene-2-methyl/phenylimidazolin-5 (4H)-ones (1&2) with 5-chloro- 3-methyl-1-substituted pyrazole-4-carboxaldehydes (3&4) gave corresponding 5-(4-benzylidene-2- methyvphenyl-5-oxoimidazolin -1-yl) amino -3-methyl-1-substituted pyrazole-4-carboxaldehydes (5-8). These were reacted with arylamines to afford corresponding Schiff's bases (9-20). All these compounds were characterized and evaluated for their antibacterial and antifungal activities. Some of them were found to exhibit significant antibacterial and antifungal activities.
