A series of novel pyrazolone derivative were synthesized by two different schemes (scheme-1 by the reaction of phenyl hydrazine and ethyl acetoacetate with substituted benzaldehydes PYR-1 to PYR-4) and (by the reaction of synthesized chalcone with phenyl hydrazine PYR-5) and characterised with its physical parameters (M.P, colour, %yield, solubility etc.). The entire synthesized compound was tested for their antimicrobial activity against Gram-positive and Gram-negative strains of bacteria and brimeshrimp bioassay was conducted for evaluation of cytotoxic activity The Investigation of antimicrobial screening data revealed that most of the tested compounds showed moderate to good antimicrobial activity. And cytotoxicity activity of compounds was also found to be satisfactory.
