PSI-352938 is a nucleoside derivative patented by Pharmasset, Inc. as an antiviral agent. PSI-352938 acts as a novel cyclic phosphate prodrug of β-D-2'-deoxy-2'-α-fluoro-2'-β-C-methylguanosine-5'-monophosphate with potent anti-HCV activity. PSI-352938 inhibits HCV genotype (GT) 1b replicon replication with 50% effective concentrations (EC50s) of 0.13 ± 0.076 μM, and active against GT 1a and 2a replicons and infectious viruses PSI-352938 retained full activity against replicons containing the S282T substitution, which confers resistance to certain 2'-substituted nucleoside/nucleotide analogs. In April 2013, because of hepatic toxicity, Gilead Sciences discontinued the development of PSI-352938.
