Background:
Daclatasvir-d6 is intended for use as an internal standard for the quantification of daclatasvir by GC- or LC-MS. Daclatasvir is a first generation direct-acting inhibitor of hepatitis C virus (HCV) non-structural protein 5A (NS5A; Kds = 8 and 210 nM for the NS5A33-202 and NS5A26-202 residues of HCV genotype 1b, respectively).1,2 It potently inhibits HCV replication in multiple HCV replicon genotypes (EC50s = 9-146 pM) with the highest potency in genotypes 1b and 4a (EC50s = 9 and 12 pM, respectively).1 Daclatasvir disrupts the subcellular localization of NS5A in Huh7.5 cells and inhibits viral RNA synthesis and virion assembly and secretion when used at a concentration of 1 nM in HCV-infected Huh7 cells.3,4 Daclatasvir also inhibits organic anion transport polypeptides 1B1 (OAT1B1) and OAT1B3 (IC50s = 1.5 and 3.27 μM, respectively).5 Formulations containing daclatasvir have been used alone and in combination with NS3/4A and NS5B inhibitors in the treatment of HCV.
