<span class="mw-page-title-main">Hepatitis C virus</span> Species of virus

The hepatitis C virus (HCV) is a small, enveloped, positive-sense single-stranded RNA virus of the family Flaviviridae. The hepatitis C virus is the cause of hepatitis C and some cancers such as liver cancer and lymphomas in humans.

NS2-3 protease is an enzyme responsible for proteolytic cleavage between NS2 and NS3, which are non-structural proteins that form part of the HCV virus particle. NS3 protease of hepatitis C virus, on the other hand, is responsible for the cleavage of non-structural protein downstream. Both of these proteases are directly involved in HCV genome replication, that is, during the viral life-cycle that leads to virus multiplication in the host that has been infected by the virus.

<span class="mw-page-title-main">Telaprevir</span> Chemical compound

Telaprevir (VX-950), marketed under the brand names Incivek and Incivo, is a pharmaceutical drug for the treatment of hepatitis C co-developed by Vertex Pharmaceuticals and Johnson & Johnson. It is a member of a class of antiviral drugs known as protease inhibitors. Specifically, telaprevir inhibits the hepatitis C viral enzyme NS3/4A serine protease. Telaprevir is only indicated for use against hepatitis C genotype 1 viral infections and has not been proven to be safe or effective when used for other genotypes of the virus. The standard therapy of pegylated interferon and ribavirin is less effective than telaprevir in those with genotype 1.

<span class="mw-page-title-main">Hepatitis C virus nonstructural protein 3</span>

Nonstructural protein 3 (NS3), also known as p-70, is a viral nonstructural protein that is 70 kDa cleavage product of the hepatitis C virus polyprotein. It acts as a serine protease. C-terminal two-thirds of the protein also acts as helicase and nucleoside triphosphatase. First (N-terminal) 180 aminoacids of NS3 has additional role as cofactor domains for NS2 protein.

<span class="mw-page-title-main">Hepatitis C virus nonstructural protein 5A</span>

Nonstructural protein 5A (NS5A) is a zinc-binding and proline-rich hydrophilic phosphoprotein that plays a key role in Hepatitis C virus RNA replication. It appears to be a dimeric form without trans-membrane helices.

<span class="mw-page-title-main">Hepatitis C virus nonstructural protein 2</span>

Nonstructural protein 2 (NS2) is a viral protein found in the hepatitis C virus. It is also produced by influenza viruses, and is alternatively known as the nuclear export protein (NEP).

A hepatitis C vaccine, a vaccine capable of protecting against the hepatitis C virus (HCV), is not yet available. Although vaccines exist for hepatitis A and hepatitis B, development of an HCV vaccine has presented challenges. No vaccine is currently available, but several vaccines are currently under development.

<span class="mw-page-title-main">Ciluprevir</span> Chemical compound

Ciluprevir was a drug used experimentally in the treatment of hepatitis C. It is manufactured by Boehringer Ingelheim and developed under the research code of BILN 2061. It was the first-in-class NS3/4A protease inhibitor to enter clinical development and tested in human. Ciluprevir is a potent competitive reversible inhibitor of NS3/4A protease from HCV genotype 1a (Ki = 0.3 nM) and 1b (Ki = 0.66 nM). It shows good selectivity for NS3 protease against representative serine and cysteine proteases, human leukocyte elastase and cathepsin B (IC50 > 30 μM).

<span class="mw-page-title-main">Discovery and development of NS5A inhibitors</span>

Nonstructural protein 5A (NS5A) inhibitors are direct acting antiviral agents (DAAs) that target viral proteins, and their development was a culmination of increased understanding of the viral life cycle combined with advances in drug discovery technology. However, their mechanism of action is complex and not fully understood. NS5A inhibitors were the focus of much attention when they emerged as a part of the first curative treatment for hepatitis C virus (HCV) infections in 2014. Favorable characteristics have been introduced through varied structural changes, and structural similarities between NS5A inhibitors that are clinically approved are readily apparent. Despite the recent introduction of numerous new antiviral drugs, resistance is still a concern and these inhibitors are therefore always used in combination with other drugs.
