NHC-diphosphate is an active phosphorylated intracellular metabolite of β-d-N4-Hydroxycytidine (NHC) as a diphosphate form[1]. NHC is a pyrimidine ribonucleoside and behaves as a potent anti-virus agent. NHC effectively inhibits the replication of venezuelan equine encephalitis virus (VEEV), Chikungunya virus (CHIKV) and hepatitis C virus (HCV)[1]. Huh-7 cells are incubated with (10-50 μM; 4 h) NHC or a McGuigan phosphoramidate prodrug of NHC.Intracellular levels of the parental compounds and phosphorylated metabolites are measured using LC-MS MS. Small amounts of NHC-monophosphate (MP) and NHC-diphosphate can be observed, while NHC-triphosphate remains the most abundant metabolite.[1].

NHC-triphosphate triammonium is an active phosphorylated intracellular metabolite of β-d-N4-Hydroxycytidine (NHC) as a triphosphate form[1]. NHC-triphosphate triammonium is a weak alternative substrate for the viral polymerase and can be incorporated into HCV replicon RNA[1][2]. 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 triammonium (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].Huh-7 cells are incubated with (10-50 μM; 4 h) NHC or a McGuigan phosphoramidate prodrug of NHC. Intracellular levels of the parental compounds and phosphorylated metabolites are measured using LC-MS MS. Small amounts of NHC-monophosphate (MP) and NHC-diphosphate (DP) can be observed, while NHC-triphosphate triammonium remains the most abundant metabolite[2].NHC-triphosphate triammonium (NHC-TP) metabolite may directly target the viral polymerase and behave as a nonobligate chain terminator. It plays a prominent role in inhibiting early negative-strand RNA synthesis, either through chain termination or mutagenesis, which may in turn interfere with correct replicase complex formation.

Orotidine 5′-monophosphate is a pyrimidine ribonucleoside and plays a role as an endogenous metabolite of human, E. coli or mouse. Orotidine 5′-monophosphate is an intermediate in the biosynthesis of uridine monophosphate (UMP). Orotidine 5′-monophosphate can be used for the study of mechanism of orotidine 5′-monophosphate decarboxylase.
