HCV Protease

CAS No.	Product Name	Inquiry
	NS5A-IN-1 NS5A-IN-1 is a prodrug of Pibrentasvir, an inhibitor of HCV NS5A.
	NS5A-IN-2 NS5A-IN-2 (Compound 33) is a potent inhibitor of NS5A. NS5A-IN-2 has extremely high potency against HCV genotype 1b, improved activity against genotype 3a (GT 3a) and good Metabolic stability.
	NS5A-IN-3 NS5A-IN-3 (Compound 15) is a potent inhibitor of NS5A. NS5A-IN-3 has extremely high potency against HCV genotype 1b, improved activity against genotype 3a (GT 3a) and good Metabolic stability. NS5A-IN-3 exhibits a higher resistance barrier than daclatasvir against genotype 1b.
	Simeprevir-13C-d3 Simeprevir-13C,d3 (TMC435-13C,d3) is the 13C- and deuterium labeled Simeprevir. Simeprevir is an oral, potent and highly specific hepatitis C virus (HCV) NS3/4A protease inhibitor with a Ki of 0.36 nM. Simeprevir inhibits HCV replication with an 50 of 7.8 nM. Simeprevir also potently suppresses SARS-CoV-2 replication and synergizes with Remdesivir. Simeprevir inhibits the main protease (Mpro) and the RNA-dependent RNA polymerase (RdRp) of SARS-CoV-2, and also modulates host immune responses.
	Telaprevir-d4 Telaprevir-d4 (VX-950-d4) is the deuterium labeled Telaprevir. Telaprevir (VX-950) is a highly selective, reversible, and potent peptidomimetic inhibitor of the HCV NS3-4A protease, the steady-state inhibitory constant (Ki) of Telaprevir is 7 nM against a genotype 1 (H strain) NS3 protease domain plus a NS4A cofactor peptide. Telaprevir inhibits SARS-CoV-2 3CLpro activity.
1009734-33-1	HZ-1157 HZ-1157 is an inhibitor of hepatitis C virus (HCV) nonstructural protein 3/4A (NS3/4A) protease.
630420-16-5	Asunaprevir Asunaprevir is a potent hepatitis C virus (HCV) non-structural protein protease inhibitor currently in Phase III clinical trials for the treatment of HCV infection.
1009119-65-6	Daclatasvir dihydrochloride Daclatasvir is a highly selective inhibitor of HCV NS5A with EC50 of 9-50 pM, for a broad range of HCV replicon genotypes and the JFH-1 genotype 2a infectious virus in cell culture.
1441674-54-9	Ledipasvir acetone Ledipasvir is an inhibitor of hepatitis C virus NS5A.
1350514-68-9	MK-5172 Grazoprevir is a hepatitis C virus protease inhibitor developed for the treatment of hepatitis C. It suppresses NS3 and NS4A, which play a role in the virus splitting its polyprotein into the functional virus proteins. Grazoprevir is often used in combination with elbasvir or ribavirin.
1377049-84-7	Velpatasvir Velpatasvir is a selective Hepatitis C virus NS 5 protein inhibitor originated by Gilead Sciences. It showed pan-genotypic activity and a high barrier to resistance in HCV replicon assays.
923604-59-5	Simeprevir Simeprevir plays an important role in HCV replication. Data from phase I and II clinical trials of TMC-435350 (TMC 435350; TMC 435; TMC-435350) to date have shown that this agent is well tolerated as a once-daily oral therapy and provides potent antiviral activity in HCV genotype 1-infected subjects, with restoration of liver enzymes and no evidence of viral breakthrough.
1163-36-6	Clemizole hydrochloride The hydrochloride salt form of clemizole, which is a histamine H1 antagonist with antitumor activity. It also has hepatitis C antiviral effect through restraining NS4B function and could also be used as an anticonvulsant in zebrafish Dravet syndrome model.
