Use of R-7128

Mericitabine (R-7128) is a nucleoside inhibitor of the HCV NS5B polymerase that acts as an RNA chain terminator and prevents elongation of RNA transcripts during replication.

In Vitro	Mericitabine (R-7128) is an oral prodrug of PSI-6130, a cytidine analogue. Pre-clinical observations demonstrated that PSI-6130 has an EC90 value of 4.6±2 μM in the HCV replicon assay. Mericitabine shows high specificity for HCV, minimal cytotoxicity and does not affect mitochondrial DNA. PSI-6130 is converted through phosphorylation by cellular kinases to an active 5′-triphosphate metabolite, which inhibits the NS5B RNA polymerase of HCV. Mericitabine demonstrates a relatively good safety profile and significant potency against HCV-1[2]. Mericitabine is a first-in class nucleoside polymerase inhibitor (NPI), which requires intracellular uptake and phosphorylation to two active triphosphates. R-7128 is an oral cytidine nucleoside analog prodrug that exhibits strong antiviral effectiveness against the HCV polymerase across all HCV genotypes[3].
