Abstract

The substantial impact of acyclic nucleoside phosphonates (ANPs) on human medicine encourages the synthesis of new ANP analogues with a potentially differentiated Antiviral spectrum. Herein, we demonstrate the functionalization of the 2-position of the (R,S)-3-hydroxy-2-(phosphonomethoxy)propyl side-chain of an inactive ANP with a polar cyano group to generate a thymine analogue with selective inhibition of hepatitis B virus (HBV) replication (SI > 302; EC50 = 0.33 μM), without significant antiretroviral activity. These findings suggest new strategies to synthesize unique ANPs with a targeted Antiviral profile.
