DESIGN AND SYNTHESIS OF BIOLOGICAL ACTIVE N-(5-P-TOLYL-1,3,4-THIADIAZOL-2-YL) BENZAMIDEANDITS DERIVATIVES WITH EVALUATION OF THEIR ANTI-BACTERIAL ACTIVITYAbstract
A number of N-(5-p-tolyl-1,3,4-thiadiazole-2-yl) benzamide derivatives were synthesized from aromatic acid. The antibacterial activity of these newly synthesized N-(5-p-tolyl-1,3,4-thiadiazole-2-yl) benzamide derivatives against Gram-positive bacteria and Gram-negative bacteria was also studied using the minimum inhibition concentration method. The synthesized compounds were showed better results for antibacterial evaluation against gram-positive (Staphylococcus aureus, Bacillus subtilis), gram-negative (Escherichia coli, Pseudomonas aeruginosa) and fungal strains (Candida albicans, A. niger) and were found to be good antibacterial and antifungal agents. Most of the derivatives showed significant antibacterial and antifungal activity against standard. Compared to other methods, the advantageous features of this methodology are operational simplicity, including excellent yields and short reaction time. The developed synthetic protocol represents a very simple and easy to handle for the synthesis of substituted N-(5-p-tolyl-1,3,4-thiadiazole-2-yl) benzamide derivatives.
