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.

The electroorganic synthesis of 2-amino-5-substituted-1,3,4-oxadiazoles from the anodic oxidation of semicarbazone has been carried out at platinum anode in acetic acid under constant potential electrolysis in an undivided cell. This is an environmentally benign method in the field of synthetic organic chemistry. The products are characterized by IR, 1H and 13C NMR, and elemental analysis.
