Synthesis of certain Pyrazoline 5-One Derivatives of 6-Methyl Nicotinicacid and Evaluation of their Antimicrobial activities

Pyrazolines are known to possess a wide variety of biological activities. Due to the wide range of biological activities that Pyrazolines posses, it was our aim to prepare pyrazolin-5-one derivatives containing substituted Nicotinic acid and to explore, their therapeutic advantage. Among the six newly synthesized pyrazoline-5-one derivatives MPZ-1 showed promising antimicrobial activity even at a concentration 250mcg/disc. and MPZ-2 showed moderate antimicrobial activity at a concentration 500mcg/disc.
