(D)- AND (L)-CYCLOHEXENYL-G, A NEW CLASS OF ANTIVIRAL AGENTS: SYNTHESIS, CONFORMATIONAL ANALYSIS, MOLECULAR MODELING, AND BIOLOGICAL ACTIVITY

Abstract

(D)- and (L)-cyclohexeneyl-G were synthesized enantioselectively starting from (R)-carvone. Both show potent and selective anti-herpesvirus activity (HSV-1, HSV-2, VZV, CMV). Molecular modeling demonstrates that both isomers are bound in the active site of HSV-1 thymidine kinase in a high-energy conformation with the base moiety orienting in an equatorial position. It is believed that the flexibility of the cyclohexene ring is essential for their antiviral activity.
