Özet

Some novel 1,3,4-thiadiazole [5-8] and 1,2,4-triazole [9-12] derivatives carrying amino acid moiety were synthesized starting from L-methionine. 1,3,4-Thiadiazole and 1,2,4-triazole scaffolds were prepared by cyclocondensation of the corresponding thiosemicarbazide and finally converted to their thiourea derivatives. Structures of the synthesized compounds [4-12] were confirmed by IR, H-1-NMR and C-13-NMR spectral data and elemental analysis. Synthesized compounds were evaluated for their antiviral and antibacterial activity. Of the screened compounds, N-{3-(methylsulfanyl)1-[5-(phenylamino)-1,3,4-thiadiazole-2-yl] propyl} benzamide 5] was identified as the most potent inhibitor of Influenza A H3N2 virus with an EC50 value of 31.4 mu M, which serves as a lead compound for prospective development. The antituberculosis activity screen of the synthesized compounds revealed
