😃Good
Catalog No. T206538Cas No. 2892688-18-3
TKB272 is an orally active antiviral agent that selectively targets the main protease (Mpro) of SARS-CoV-2, effectively inhibiting the infection and replication of various strains, including Omicron variants (such as XBB.1.5 and EG.5.1). It exhibits an enzyme inhibitory activity with an IC50 of 0.7 µM against SARS-CoV-2WK-521 Mpro and shows potent antiviral activity at the cellular level with an EC50 as low as 2.6 nM in HeLahACE2-TMPRSS2 cells against the BQ.1.1 strain. TKB272 also has a CC50 of 98 µM, indicating low cytotoxicity. Furthermore, it demonstrates a significant suppression of SARS-CoV-2XBB.1.5 replication in the B6.Cg-Tg(K18-hACE2)2-Prlmn/J transgenic mouse model, suggesting potential use in the research of SARS-CoV-2 infections.

Calculator
In Vivo Formulation Calculator (Clear solution)
Please enter your animal experiment information in the following box and click Calculate to obtain the stock solution preparation method and in vivo formula preparation method:
For example, if the intended dosage is 10 mg/kg for animals weighing 20 g , with a dosing volume of 100 μL per animal, and a total of 10 animals are to be administered, using a formulation of 
10% DMSO+ 40% PEG300+ 5% Tween 80+ 45% Saline/PBS/ddH2O , the resulting working solution concentration would be 2 mg/mL.Stock Solution Preparation:
Dissolve 2 mg of the compound in 100 μL DMSO to obtain a stock solution at a concentration of 20 mg/mL . If the required concentration exceeds the compound's known solubility, please contact us for technical support before proceeding.
Preparation of the In Vivo Formulation:
1) Add 100 μL of the DMSO stock solution to 400 μL PEG300 and mix thoroughly until the solution becomes clear.
2) Add 50 μL Tween 80 and mix well until fully clarified.
3) Add 450 μL Saline,PBS or ddH2O and mix thoroughly until a homogeneous solution is obtained.
This example is provided solely to demonstrate the use of the In Vivo Formulation Calculator and does not constitute a recommended formulation for any specific compound. Please select an appropriate dissolution and formulation strategy based on your experimental model and route of administration.
