Synthesis of 5-(4-aminophenyl)-2-(arylamino)-1,3,4-thiadiazoles and their schiff base derivatives as antimycobacterial agents

The condensation reaction of 5-(4-aminophenyl)-N-aryl-1,3,4-thiadiazol-2-ylamines with salicyl-aldehyde, 3-hydroxybenzaldehyde, 4-hydroxybenzaldehyde, 5-bromosalicylaldehyde, 5-chlorosalicyl-aldehyde, 4-methoxybenzaldehyde, 3-nitrobenzaldehyde, and 4-nitrobenzaldehyde results in series of new Schiff bases. The synthesized compounds were tested for their antimicrobial efficiency against Mycobacterium smegmatis PTCC 1307 in vitro. All compounds showed significant antiproliferative activity against M. smegmatis
