Synthesis of a Series of Novel 2-Amino-5-substituted 1,3,4-oxadiazole and 1,3,4-thiadiazole Derivatives as Potential Anticancer, Antifungal and Anti-bacterial Agents

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, antibac-terial and antifungal activities. Methods: Twenty-seven derivatives were synthesized by iodine-mediated cyclization of semicarba-zones or thiosemicarbazones obtained from condensation of semicarbazide or thiosemicarbazide and aldehydes. The structures were confirmed by1H-NMR,13C-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 faecal-is, MSSA and MRSA with MIC value ranging between 4 to 64 μg/mL. Compound (2g) showed anti-fungal activity against Candida albicans (8 μg/mL) and Aspergillus niger (64 μg/mL). Compound (1o) exhibited high cytotoxic activity against HepG2 cell line (IC50 value 8.6 μM) which is compara-ble 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.

Synthesis, telomerase inhibitory and anticancer activity of new 2-phenyl-4H-chromone derivatives containing 1,3,4-oxadiazole moiety

Based on previous studies, 66 2-phenyl-4H-chromone derivatives containing amide and 1,3,4-oxadiazole moieties were prepared as potential telomerase inhibitors. The results showed most of the title compounds exhibited significantly inhibitory activity on telomerase. Among them, some compounds demonstrated the most potent telomerase inhibitory activity (IC50 50 = 6.41 μM). In addition, clear structure–activity relationships were summarised, indicating that the substitution of the methoxy group and the position, type and number of the substituents on the phenyl ring had significant effects on telomerase activity. Among them, compound A33 showed considerable inhibition against telomerase. Flow cytometric analysis showed that compound A33 could arrest MGC-803 cell cycle at G2/M phase and induce apoptosis in a concentration-dependent way. Meanwhile, Western blotting revealed that this compound could reduce the expression of dyskerin, which is a fragment of telomerase.

A convenient methodology has been developed for the synthesis of substituted 2-amino-1,3,4-oxadiazoles from corresponding acylthiosemicarbazides using catalytic amount of iodine/KI in the presence of Oxone as a bulk oxidant. This offers the adv

Mild and convenient one-pot synthesis of 2-amino-1,3,4-oxadiazoles promoted by trimethylsilyl isothiocyanate (TMSNCS)

A mild, convenient, and efficient one-pot synthesis of amino-1,3,4- oxadiazoles is described. In situ preparation of various thiosemicarbazides by the reaction of different carboxylic acid hydrazides with trimethylsilyl isothiocyanate (TMSNCS), followed by cyclodesulfurization of thiosemicarbazides under basic conditions in the presence of I2/KI resulted in 2-amino-1,3,4-oxadiazoles in high yields (79-94%).
