Abstract

2',3'-Dideoxy-3'-fluorothymidine (FddThd), 2',3'-didehydro-2',3'- dideoxythymidine (ddeThd), and 3'-fluoro-5-methyl-deoxycytidine (FddMeCyt) are, in their triphosphate forms, selective inhibitors of human immunodeficiency virus type 1 reverse transcriptase. We report that 0.3 microM FddThd, FddMeCyt, or ddeThd as well as 3'-chloro-5-methyl-deoxycytidine (ClddMeCyt) or 3'-amino-5-methyl-deoxycytidine (AddMeCyt) almost completely blocked production of hepatitis B virus (HBV) particles by HBV DNA-transfected cell line 2.2.15 in vitro. Only at an at least 10-fold-higher concentration was a cytotoxic effect observed. These results indicate that FddThd, FddMeCyt, ClddMeCyt, AddMeCyt, and ddeThd are potent anti-HBV agents in vitro.
