Lomibuvir
Based on 2 publication(s) in Google Scholar
Lomibuvir (VX-222), a selective, non-nucleoside polymerase inhibitor, targets thumb pocket 2 of the HCV NS5B polymerase (RdRp) with a Kd of 17 nM. Lomibuvir inhibits the 1b/Con1 HCV subgenomic replicon with an EC50 of 5.2 nM. Lomibuvir preferentially inhibits elongative RNA synthesis rather than de novo-initiated RNA synthesis.

Lomibuvir (VX-222) inhibits WT HCV 1b/Con1 replicon with an EC50 of 5.2 nM. Lomibuvir inhibits M423T, L419M and I482L (mutant replicons) with EC50s of 79.8, 563.1, 45.3 nM, respectively. Lomibuvir reduces de novo initiation slightly but also shows strong inhibition of primer extension. The IC50 of Lomibuvir for primer-extended RNA synthesis is 31 nM[1].
Lomibuvir is a non-nucleoside, allosteric inhibitor of the hepatitis C virus NS5B polymerase[2].

Select the appropriate dissolution method based on your experimental animal and administration route.
- For the following dissolution methods, please ensure to first prepare a clear stock solution using an In Vitro approach and then sequentially add co-solvents:
- To ensure reliable experimental results, the clarified stock solution can be appropriately stored based on storage conditions. As for the working solution for In Vivo experiments, it is recommended to prepare freshly and use it on the same day.
- The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.
Add each solvent one by one: 10% DMSO 40% PEG300 5% Tween-80 45% Saline
Solubility: 2.5 mg/mL (5.61 mM); Suspended solution; Need ultrasonic
