Molarity Calculator

Simeprevir (TMC435; TMC435350) is an oral, potent and highly specific hepatitis C virus (HCV) NS3/4A protease inhibitor with a K_i of 0.36 nM. Simeprevir inhibits HCV replication with an EC₅₀ of 7.8 nM. Simeprevir also potently suppresses SARS-CoV-2 replication and synergizes with Remdesivir. Simeprevir inhibits the main protease (M^pro) and the RNA-dependent RNA polymerase (RdRp) of SARS-CoV-2, and also modulates host immune responses.

: Simeprevir purchased from MedChemExpress. Usage Cited in: Eur J Med Chem. 2018 Jan 1;143:1053-1065. [Abstract]; Huh7.5 cells are infected with HCV and simultaneously treated with 7f (10 μM) or DAA (0.04 μM Simeprevir, 0.08 μM Sofosbuvir, or 16 pM Daclatasvir) or 7f plus DAA.

: Simeprevir purchased from MedChemExpress. Usage Cited in: Biomed Res Int. 2017;2017:1236801. [Abstract]; Huh7.5 (HCV+) cells are treated with 1 μM of Simeprevir or solvent control. At 24 hours, the cells are washed and continuously incubated with fresh culture media containing drugs again for 48 hours. The cultural supernatants are then harvested and directly incubated to naïve Huh7.5 cells. After been passaged 1~3 times, the newly infected cells are treated with 1 μM of Simeprevir for 72 hours. Intracellular proteins are extracted and detected with WB.

: Simeprevir purchased from MedChemExpress. Usage Cited in: J Med Chem. 2016 Nov 23;59(22):10268-10284. [Abstract]; Huh7.5 cells are infected with HCV (45 IU/cell) and simultaneously treated with Simeprevir (A, 0.025 μM), Sofosbuvir (B, 0.1 μM), or Daclatasvir (C, 16 pM) alone or with 1 (6.25 μM).

: Simeprevir purchased from MedChemExpress. Usage Cited in: Int J Radiat Oncol Biol Phys. 2016 Nov 15;96(4):867-876. [Abstract]; Simeprevir inhibits DNA damage repair following irradiation. U251, BT474, and HepG2 cells are pretreated with Simeprevir or DMSO and irradiated at a dose of 6 Gy. After 6 hours, prolongation of γH2AX foci is detected in Simeprevir-treated cells along with decreased phosphorylation of DNA-PKcs, indicating impaired nonhomologous end-joining repair.

In Vivo:

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.

Protocol 1

Add each solvent one by one: 5% DMSO 40% PEG300 5% Tween-80 50% Saline
Solubility: 2.5 mg/mL (3.33 mM); Suspended solution; Need ultrasonic
Protocol 2

Add each solvent one by one: 10% DMSO 40% PEG300 5% Tween-80 45% Saline
Solubility: ≥ 1.43 mg/mL (1.91 mM); Clear solution

This protocol yields a clear solution of ≥ 1.43 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (14.3 mg/mL) to 400 μL PEG300, and mix evenly; then add 50 μL Tween-80 and mix evenly; then add 450 μL Saline to adjust the volume to 1 mL.
Preparation of Saline: Dissolve 0.9 g sodium chloride in ddH₂O and dilute to 100 mL to obtain a clear Saline solution.
Protocol 3

Add each solvent one by one: 10% DMSO 90% Corn Oil
Solubility: ≥ 1.43 mg/mL (1.91 mM); Clear solution

This protocol yields a clear solution of ≥ 1.43 mg/mL (saturation unknown). If the continuous dosing period exceeds half a month, please choose this protocol carefully.
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (14.3 mg/mL) to 900 μL Corn oil, and mix evenly.

Help & FAQs

Do most proteins show cross-species activity?
Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
