NHC-triphosphate is an intracellular metabolite of β-d-N4-Hydroxycytidine (NHC) as a triphosphate form. NHC-triphosphate is a weak alternative substrate for the viral polymerase and changes the mobility of the product in polyacrylamide electrophoresis gels[1].

Target	IC50: alternative substrate for the viral polymerase[1]
In Vitro	In an intracellular metabolism assay, HCV replicon cells are treated with 10 μM 3H-labeled NHC, and intracellular nucleotide levels are determined after 1, 2 and 8 hours incubations. NHC is rapidly convered into the mono-, di-, and triphosphate forms, and NHC-TP reaches up to 71.12 pM after 8 hours[1]. NHC-triphosphate (NHC-TP)(5-40 μM) absence leads to full-length polymerization products, it can be a weak alternative substrate. In addition, incorporation of NHC-TP instead of CTP increases the molecular weight of the polymerization product by 16 (one extra oxygen) for each event and an obvious electrophoretic shift is observed in cell-free HCV NS5B polymerization reactions[1].
