Abstrakt: Background: Many compounds containing a five-membered heterocyclic ring display exceptional chemical properties and versatile biological activities.
Objective: The objective of the present study was to prepare the 5-substituted 2-amino-1,3,4- oxadiazole and 2-amino-1,3,4-thiadiazole derivatives and evaluate their potential anticancer, antibacterial and antifungal activities.
Methods: Twenty-seven derivatives were synthesized by iodine-mediated cyclization of semicarbazones or thiosemicarbazones obtained from condensation of semicarbazide or thiosemicarbazide and aldehydes. The structures were confirmed by 1 H-NMR, 13 C-NMR and MS spectra. The antibacterial and antifungal activities were evaluated by diffusion method and the anticancer activities were evaluated by MTT assay.
Results: Twenty-seven derivatives have been synthesized in moderate to good yields. A number of derivatives exhibited potential antibacterial, antifungal and anticancer activities.
Conclusion: Compounds (1b, 1e and 1g) showed antibacterial activity against Streptococcus faecalis, MSSA and MRSA with MIC value ranging between 4 to 64 μg/mL. Compound (2g) showed antifungal activity against Candida albicans (8 μg/mL) and Aspergillus niger (64 μg/mL). Compound (1o) exhibited high cytotoxic activity against HepG2 cell line (IC 50 value 8.6 μM) which is comparable to the activity of paclitaxel, and is non-toxic on LLC-PK1 normal cell line. The structure activity relationship and molecular docking study of the synthesized compounds have also been reported.
