Secutrelvir
Based on 1 Customer Validation
Secutrelvir is an oral SARS-CoV-2 3C-like protease (3CLpro) inhibitor and antiviral agent, with IC50 values of 0.655 nM and 0.697 nM against SARS-CoV-2 3CLpro, respectively. Secutrelvir forms a reversible covalent bond with the catalytic cysteine C145 of SARS-CoV-2 3CLpro, thereby inhibiting viral replication. Secutrelvir exhibits activity against multiple SARS-CoV-2 variants and can be used in research related to coronavirus disease 2019 (COVID-19).

Biological Activity
Secutrelvir (S-892216) exhibits antiviral activity against multiple SARS-CoV-2 strains (including Omicron variants) in VeroE6/TMPRSS2 cells with an EC50 range of 2.27 to 12.5 nmol/L[1].
Secutrelvir (S-892216) exhibits antiviral activity against multiple SARS-CoV-2 strains (including Omicron variants) in hAECs with an EC90 range of 2.31 to 2.41 nmol/L[1].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
Secutrelvir (0.1-10 mg/kg; p.o.; twice daily; 5 days) exhibits dose-dependent therapeutic efficacy against COVID-19 in SARS-CoV-2-infected Syrian hamsters, including up to 2.9-log reductions in lung virus titers and 2.3-log reductions in nasal turbinate virus titers at the 10 mg/kg dose, plus suppression of lung inflammation and body weight loss[2].
S-892216 (0.1-10 mg/kg; p.o.; twice daily; 2 days) exhibits potent dose-dependent antiviral efficacy against SARS-CoV-2 Gamma strain in BALB/cAJcl mice, with maximum efficacy achieved at 3 mg/kg twice daily, and equivalent activity to ensitrelvir at a 32-fold lower dose[3].

Animal Model:Syrian hamsters (intranasally inoculated with SARS-CoV-2 Omicron BE.1/BA.5-like)[2]
-
Dosage:0.1 mg/kg; 1 mg/kg; 10 mg/kg
-
Administration:p.o.; twice daily; 5 days
-
Result:Reduced lung virus titer by 1.9-log and nasal turbinates virus titer by 1.8-log at 1 mg/kg, measured 3 days post-infection.\nReduced lung virus titer by 2.9-log and nasal turbinates virus titer by 2.3-log at 10 mg/kg, measured 3 days post-infection.\nSuppressed SARS-CoV-2-induced lung inflammation and body weight loss in a dose-dependent manner.
-
Animal Model:BALB/cAJcl (female, 5 weeks of age, intranasally inoculated with SARS-CoV-2 Gamma strain)[3]
-
Dosage:0.1 mg/kg; 0.3 mg/kg; 1 mg/kg; 3 mg/kg; 10 mg/kg
-
Administration:p.o.; twice daily; 2 days
-
Result:Achieved statistically significant reduction in lung virus titers at 0.3 mg/kg.\nReached maximum efficacy at 3 mg/kg, with viral titers reduced to near the lower limit of quantification (LLOQ = 1.80 log10 TCID50/mL).\nAchieved viral titer reduction comparable to the ensitrelvir 32 mg/kg group at 1 mg/kg.

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.
