title: Anti-hepatitis B virus activity of new 1,2,4-triazol-2-yl- and 1,3,4-oxadiazol-2-yl-2-pyridinone derivatives.
abstract: A number of 1,3,4-oxadiazole, 3-9, and 1,2,4-triazole derivatives, 13-15, were synthesized starting form the acid hydrazide 1. The 1,3,4-thiadiazole derivative 12 was prepared from the substituted phenylthiosemicarbazide derivative 11 by treatment with sulfuric acid. The aryl hydrazone derivatives 10a-c were synthesized by reaction of the hydrazide 1 with the corresponding ketones. The thioalkyl derivatives 16a-e were prepared by akylation of the thiol derivatives 3 and 13 with different alkylating agents. The newly synthesized compounds were tested for their anti-HBV activity and some of these compounds showed high antiviral activity.
