Abstract
Indole-2,3-dione (isatin) and its derivative have been recated with 2 and 4 substituted 1,3,4-thiadiazole derivative form Schiff bases of these compounds were synthesized in the presence of alcohol. Their chemical structure have been confirmed by mean of their IR and 1HNMR. Antimicrobial screening of synthesized compounds was done by well diffusion method against 4 pathogenic becteria and 2 pathogenic fungi. Amongst the tested compounds 5-fluoro-3-[(5-sulfanyl-1,3,4-thiadiazol-2-yl)imino]-1,3-dihydro-2H-indol-2-one, 5-methyl-3-[(5-sulfanyl-1,3,4-thiadiazol-2-yl)imino]-1,3-dihydro-2H-indol-2-one,and 5-nitro-3-[(5-sulfanyl-1,3,4-thiadiazol-2-yl)imino]-1,3-dihydro-2H-indol-2-one exhibit significant antibacterial activity and 5-chloro-3-[(5-sulfanyl-1,3,4-thiadiazol-2-yl)imino]-1,3-dihydro-2H-indol-2-one, 5-fluoro-3-[(5-sulfanyl-1,3,4-thiadiazol-2-yl)imino]-1,3-dihydro-2H-indol-2-one and 5-methyl-3-[(5-sulfanyl-1,3,4-thiadiazol-2-yl)imino]-1,3-dihydro-2H-indol-2-one showed favourable antifungal activity
