SYNTHESIS OF NOVEL SCHIFF’S BASES AND THEIR BIOLOGICAL ACTIVITIESAbstract
A new series of Schiff’s base compounds were synthesized by condensation of 1-(4-amino-4 phenyl) 3-phenyl triazene-1-ol) and substituted aldehyde and gave high yields of target compounds. Antimicrobial activity of compounds has been tested against bacterial and fungal species, namely gram-positive bacteria as S. aureus and S. pyogenes, gram-negative bacteria as E. coli and P. aeruginosa, and fungal species C. albicans and A. clavatus are selected based on their clinical and pharmacological importance. Bacterial and fungal tests were performed under the same conditions using Cefixime and Griseofulvin as standard drugs. It has been found that synthesized Schiff’s base has shown efficient antibacterial and anti-fungal activities. Thus they can be revealed as potent antimicrobial compounds. They are widely used for industrial purposes and also exhibit a broad range of biological activities. The structures of synthesized compounds were confirmed by TLC, melting point, Infrared spectroscopy, and proton nuclear magnetic resonance spectroscopy (1HNMR) data.
