Lufotrelvir (PF-07304814) is a phosphate prodrug of PF-00835231, and there is no statistical difference in antiviral potency of Lufotrelvir in vero cells expressing high levels of the efflux transporter P-glycoprotein, showing strong antiviral activity by inhibiting coronavirus family 3CL protease activity.<sup><a class="sref" href="#s_ref">[1]</a></sup>

Cell Research Cell lines VeroE6-ACE2 (Kideney), VeroE6-egfp (Kidney), A549-ACE2 (Lung) and MRC5 (Lung, h229E virus)
Concentrations 0.01-1000 µM
Incubation Time --
Method

These cell lines were infected with the SARS-CoV-2 Washington strain 1 (WA1-EPI_ISL_404895) or the Belgium/GHB-03021/2020 strain (GHB-03021-EPI_ISL_407976), respectively, which have identical 3CL<sup>pro</sup> amino acid sequences and conducted with a cytopathic effect (CPE) assay.

Working concentration: mg/ml;

Method for preparing DMSO master liquid: mg drug pre-dissolved in μL DMSO ( Master liquid 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 master liquid, next addμL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH2O, mix and clarify.

Method for preparing in vivo formulation: Take μL DMSO master liquid, next add μL Corn oil, mix and clarify.

Note: 1. Please make sure the liquid is clear before adding the next solvent.
2. Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such
as vortex, ultrasound or hot water bath can be used to aid dissolving.
