Abstract

Novel antipyrine derivatives bearing pyran, pyridopyrimidine, chromene, benzothiazole, indole, pyrazole and pyridazine moieties were synthesized by using 2-cyano-N-(1,5-dimethyl-3-oxo-2-phenyl-2,3-dihydro-1H-pyrazol-4-yl)acetamide (1) as a staring material. The newly synthesized compounds were evaluated for their antimicrobial activities based on inhibition diameter zone against Gram-positive and Gram-negative bacteria.
