title: Synthesis of pyrrolo[2,3-d]pyrimidine nucleoside derivatives as potential anti-HCV agents.
abstract: Several Toyocamycin (4) analogues were examined for their ability to inhibit HCV RNA in a replicon assay. Among the compounds examined 4-methylthio (18) and 5-carboxamide oxime derivatives (23 and 27) of Toyocamycin were found to have good activity and selectivity.
