Aim: To synthesize and evaluate 4-aminoantipyrine related schiff’s bases as antibacterial agents. Objective: To synthesize, purify, characterize and evaluate 4-aminoantipyrine. Method: Schiff bases derived from 4-aminoantipyrine play a vital role in biological and pharmacological activities. Knowing the importance of 4-aminoatipyrine schiff bases and their analogues wide varieties of bioactivities like analgesic, antiviral, antipyretic, anti-rheumatic, antimicrobial and anti-inflammatory activities have been widely studied. 4-aminoantipyrine compounds C1 (anisaldehyde), C2 (p-hydroxybenzaldehyde) and C3(vanillin) were prepared by condensation between 4-amino antipyrine and substituted aromatic benzaldehydes. The products were purified by recrystallization by using ethanol, characterized by IR spectroscopy. The N-H stretching in 4-aminoantipyrine is shown at 3430 cm-1 and -3325 cm-1. The -HC=N- stretching is observed in the range of 1508-1504 cm-1 The –OCH3 stretching is found at 1888 cm-1. 4-amino antipyrine related schiff’s bases evaluated their activity as antimicrobials in-vitro by spread plate method against E.coli. Schiff bases have potent antibacterial activity with gram negative bacteria E.coli. Results: Synthesis and characterization of a schiff bases derived from substituted benzaldehydes and 4-aminoantipyrine was evaluated and characterized with the IR spectroscopic techniques and schiff bases have shown potent antibacterial activity against E.Coli.
