Molarity Calculator

Paritaprevir (ABT-450) is a potent, orally active and antiviral non-structural protein 3/4A (NS3/4A) protease inhibitor with EC50s of 1 and 0.21 nM against HCV 1a and 1b, respectively. Paritaprevir is also a SARS-CoV 3CLpro inhibitor with an IC50 of 1.31 μM. Paritaprevir is metabolized primarily by cytochrome P450 (CYP) 3A. The plasma concentration and half-life of Paritaprevir can be enhanced by Ritonavir (a CYP450 inhibitor).

Description

Paritaprevir (ABT-450) is a potent, orally active and antiviral non-structural protein 3/4A (NS3/4A) protease inhibitor with EC50s of 1 and 0.21 nM against HCV 1a and 1b, respectively. Paritaprevir is also a SARS-CoV 3CLpro inhibitor with an IC50 of 1.31 μM. Paritaprevir is metabolized primarily by cytochrome P450 (CYP) 3A. The plasma concentration and half-life of Paritaprevir can be enhanced by Ritonavir (a CYP450 inhibitor)[1][2][3][4].

IC50 & Target

EC50: 1 nM (HCV 1a), 0.21 nM (HCV 1b)[1]
IC50: 1.31 μM (SARS-CoV 3CLpro)[3]
In Vitro

Paritaprevir has in vitro antiviral activity against HCV GT1-4 and GT6 (EC50 range, 0.09 to 19 nM), with an EC50 of 0.09 nM against GT4a[2].

In Vivo

The combination of Paritaprevir, Ritonavir, Ombitasvir (an NS5A protein inhibitor), and Dasabuvir (an NS5B non-nucleoside polymerase inhibitor) with or without RBV has been approved to treat HCV genotype 1 infections[1][4].
The acute toxicity of Paritaprevir is considered to be low. Single oral doses of ≤600 mg/kg in rats and ≤100 mg/kg in dogs produces no mortality and were well tolerated. However, since Paritaprevir is administered without ritonavir as a PK enhancer, the exposures are low, especially in male rats (rat 600 mg/kg, males: Cmax 1.82 μg/mL, AUC0-24 8.89 μg·h/mL; dog 100 mg/kg, mean: Cmax 61.3 μg/mL, AUC0-24 285 μg·h/mL).

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:  10% DMSO    40% PEG300    5% Tween-80    45% Saline

    Solubility: ≥ 2.08 mg/mL (2.72 mM); Clear solution

    This protocol yields a clear solution of ≥ 2.08 mg/mL (saturation unknown).

    Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (20.8 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 2

    Add each solvent one by one:  10% DMSO    90% Corn Oil

    Solubility: ≥ 2.08 mg/mL (2.72 mM); Clear solution

    This protocol yields a clear solution of ≥ 2.08 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 (20.8 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.
