Synthesis and In-Vitro Antimicrobial Activity of 4-(Piperazin-1- Ylcarbonyl) Aniline – An Amide Derivative of P-Aminobenzoic Acid

An amide derivative of P-aminobenzoic acid (PABA) has been synthesized from piperazine by initial conversion of PABA into its hydrochloride salt for protection of amino group from self-polymerization. The compound identity has been characterized by Melting point, Elemental Analysis, TLC, UV-Visible spectroscopy, IR spectroscopy and NMR spectroscopy. The antibacterial activity of the compound has been studied against E.coli, S.aureus, B.subtilis and P.aeruginosa using tetracycline as a standard. Antifungal activity of the compound has been studied against C.albicans and A.niger using clotrimazole as a standard. The synthesized compound has been found to possess significant antibacterial and antifungal activities as compared to the standard drugs used.
