In the present study, a new series of 2,5-disubstituted-1,3,4-thiadiazole tethered 1,2,4-triazole, 1,3,4-thiadiazole, 1,3,4-oxadiazole and Schiff base derivatives were synthesized and characterized by IR, ¹H-NMR, (13)C-NMR, MS and elemental analyses. All compounds were screened for their antibacterial, antifungal and antiproliferative activity. Some of the synthesized derivatives have displayed promising biological activity.
Keywords: 1,2,4-triazole; 1,3,4-oxadiazole; 1,3,4-thiadiazole; Schiff base; antimicrobial activity; antitumor activity.
