Faldaprevir is an orally effective, selective, non-covalent HCV NS3 4A protease inhibitor with high inhibitory activity against HCV 1a and 1b genotypes (Ki=2.6 nM &2.0 nM).Faldaprevir inhibits viral replication by blocking the breakdown of viral precursor proteins, and is well tolerated with good antiviral activity against hepatitis C virus.

Vaniprevir is a non-covalent competitive HCV NS3 4A protease inhibitor, an antiviral drug that acts directly on the hepatitis C virus. Vaniprevir blocks the viral replication process by inhibiting the activity of HCV NS3 4A protease.

Simeprevir (TMC435) is a potent HCV NS3 4A protease inhibitor, and inhibits HCV replication with EC50 of 8 nM.

Boceprevir (SCH 503034) is a novel, potent, highly selective, orally bioavailable HCV NS3 protease inhibitor with Ki of 14 nM in both enzyme assay and EC90 of 350 nM in cell-based replicon assay.

Telaprevir (Incivek) (VX-950) is an effective inhibitor of HCV NS3-4A serine protease (IC50: 0.35 μM).

BI 653048 is a selective, orally active nonsteroidal glucocorticoid agonist (IC50: 55 nM) and an HCV NS3 protease inhibitor.

BI-1230 is a potent inhibitor of HCV NS3 protease, exhibiting efficacy in the low nanomolar range, and notably suppresses viral replication. This compound demonstrates high selectivity, distinguishing effectively between other serine cysteine proteases. Additionally, BI-1230 exhibits favorable pharmacokinetic (PK) properties[1].

Ciluprevir is an effective and selective HCV NS3 protease inhibitor with proven antiviral effect in humans. Ciluprevir may be an antiviral agent for individuals infected with non-genotype-1 HCV. In vitro sensitivity studies with Ciluprevir showed a decrea

Voxilaprevir is an inhibitor of hepatitis C virus (HCV) nonstructural (NS) protein 3 4A protease.

MK-6325 is a potent inhibitor of the HCV NS3 4A protease.

Paritaprevir (ABT450) is an inhibitor of non-structural protein 3 4A protease with EC50 values of 1 and 0.21 nM for HCV 1a and HCV 1b, respectively.

Paritaprevir free base(ABT-450) is an orally bioavailable, synthetic acylsulfonamide inhibitor of the hepatitis C virus (HCV) protease complex comprised of non-structural protein 3 and 4A (NS3 NS4A), with potential activity against HCV genotype 1. Upon administration, paritaprevir reversibly binds to the active center and binding site of the HCV NS3 NS4A protease and prevents NS3 NS4A protease-mediated polyprotein maturation. This disrupts both the processing of viral proteins and the formation of the viral replication complex, which inhibits viral replication in HCV genotype 1-infected host cells. NS3, a serine protease, is essential for the proteolytic cleavage of multiple sites within the HCV polyprotein and plays a key role during HCV ribonucleic acid (RNA) replication. NS4A is an activating factor for NS3. HCV is a small, enveloped, single-stranded RNA virus belonging to the Flaviviridae family, and infection is associated with the development of hepatocellular carcinoma (HCC).

Vedroprevir, also known as GS9451, is a selective hepatitis C virus (HCV) NS3 protease inhibitor in the development of the treatment of genotype 1 (GT1) HCV infection.
