A library of 3,5-disubstituted-1,2,4-oxadiazoles 7–9 and their bioisosters, 1,3,4-oxadiazole 14 and 1,3,4-thiadiazole 16, were synthesized and evaluated in vitro for their anticancer potential against a panel of six human cancer cell lines. The key step in the synthesis of oxadiazoles 7–9 involve coupling of amidoxime 6 with an appropriate carboxylic acid followed by thermal cyclization. The bioisosteres

A series of 3,5‐disubstituted‐1,2,4‐oxadiazoles has been prepared and evaluated for phosphodiesterase inhibition (PDE4B2). Among the prepared 3,5‐disubstituted‐1,2,4‐oxadiazoles, compound 9a is the most potent inhibitor (PDE4B2 IC50 = 5.28 μm). Structure–activity relationship studies of 3,5‐disubstituted‐1,2,4‐oxadiazoles revealed that substituents 3‐cyclopentyloxy‐4‐methoxyphenyl group at 3‐position and cyclic ring bearing heteroatoms at 5‐position are important for activity. Molecular modeling study of the 3,5‐disubstituted‐1,2,4‐oxadiazoles with PDE4B has shown similar interactions of 3‐cyclopentyloxy‐4‐methoxyphenyl group; however, heteroatom ring is slightly deviating when compared to Piclamilast. 3‐(3‐Cyclopentyloxy‐4‐methoxyphenyl)‐5‐(piperidin‐4‐yl)‐1,2,4‐oxadiazole (9a) exhibited good analgesic and antiinflammatory activities in formalin‐induced pain in mice and carrageenan‐induced paw edema model in rat.
