VPC285785

VPC285785 is an orally active SARS-CoV-2 main protease inhibitor with an IC₅₀ of 0.8 μM and a K_d of 2.7 μM. VPC285785 functionally inhibits the viral main protease-mediated processing of viral polyprotein precursors required for viral replication. VPC285785 reduces viral loads in the liver, brain and spleen tissues of MHV-infected mice. VPC285785 is applicable to the research of coronavirus infections.

Biological Activity

제품 설명

In Vitro

VPC285785 (10 μM) exerts weak inhibitory effects on human cathepsin L (CatL), with only 15% inhibition observed at the concentration of 10 μM^[1].

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

In Vivo

VPC285785 (150 mg/kg; p.o.; once daily; for 3 consecutive days) significantly reduces viral loads in the liver, brain and spleen of MHV-A59-infected mice while preserving their liver and kidney functions^[1].

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

Animal Model:

Balb/CJ (female, 8-10 weeks old, 18.5-26.5 g, intranasal infection with MHV-A59)^[1]
Dosage:

150 mg/kg
Administration:

p.o.; once daily; 3 days (day 1, 2, 3 post-infection)
Result:

Reduced liver enzyme levels: alanine transaminase (ALT) 65.5 U/L, aspartate aminotransferase (AST) 126.0 U/L, and total protein (TP) 54.16 g/L.
Showed less pronounced decrease in blood urea nitrogen (BUN) levels.
Lowered white blood cell (WBC) counts.
Achieved statistically significant reduction in viral load in the liver, brain, and spleen; no significant differences in viral load observed in the lung, heart, or kidney.

Help & FAQs

How should lyophilized recombinant proteins be reconstituted and stored?

1. Before opening the cap, centrifuge the vial at 13000 rpm for 20-30 seconds. This step will ensure that any lyophilized powder that may have adhered to the cap or walls is collected at the bottom of the vial, minimizing the risk of product loss.
