HCV replicon cells are treated with 10 μM 3H-labeled NHC in an intracellular metabolism test. After 1, 2, and 8 hours of incubation, intracellular nucleotide levels are measured. NHC is quickly transformed into the mono-, di-, and triphosphate forms; within 8 hours, NHC-TP can reach 71.12 pM[1]. In the absence of NHC-triphosphate triammonium (NHC-TP) (3-5 μM), full-length polymerization products result, and it may be a poor substitute substrate. Furthermore, in cell-free HCV NS5B polymerization events, an evident electrophoretic shift is seen, and the molecular weight of the polymerization product increases by 16 (one extra oxygen) upon insertion of NHC-TP rather than CTP[1]. NHC (10–50 μM; 4 h) or a McGuigan phosphoramidate prodrug of NHC are cultured in Huh-7 cells. LC-MS/MS is used to evaluate the intracellular levels of the primary chemicals and phosphorylated metabolites. While NHC-triphosphate triammonium continues to be the most prevalent metabolite, trace levels of NHC-monophosphate (MP) and NHC-diphosphate (DP) are also visible[2]. The metabolite NHC-triphosphate triammonium (NHC-TP) may act as a nonobligate chain terminator and directly target the viral polymerase. Through chain termination or mutagenesis, it inhibits early negative-strand RNA synthesis in a significant way. This can potentially obstruct the proper assembly of replicase complexes.

*Note: Please select an appropriate solvent for the preparation of stock solution based on your experiment needs. For most products, DMSO can be used for preparing stock solutions (e.g. 5 mM, 10 mM, or 20 mM concentration); some products with high aqueous solubility may be dissolved in water directly. Solubility information is available at the above Solubility Data section. Once the stock solution is prepared, aliquot it to routine usage volumes and store at -20°C or -80°C. Avoid repeated freeze and thaw cycles.
Calculation results
Working concentration： mg/mL；
Method for preparing DMSO stock solution： mg drug pre-dissolved in μL DMSO (stock solution concentration mg/mL). Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug.
Method for preparing in vivo formulation:：Take μL DMSO stock solution, next add μL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH2O，mix and clarify.
(1) Please be sure that the solution is clear before the addition of next solvent. Dissolution methods like vortex, ultrasound or warming and heat may be used to aid dissolving.
(2) Be sure to add the solvent(s) in order.
