WebHCV infection is associated with immune dysregulation and B cell Non-Hodgkins lymphoma (HCV-NHL). We have previously shown in vitro that HCV core protein differentially regulates T and B cell functions through two negative signaling pathways, programmed death-1 (PD-1) and suppressor of cytokine signaling-1 (SOCS-1). WebHepatitis C virus (HCV) is a positive sense, single-stranded RNA virus in the Flaviviridae family. It causes acute hepatitis with a high propensity for chronic infection. ... ribavirin and small molecule inhibitors of the virally encoded NS3/4A protease, although better therapeutic options are needed with greater antiviral efficacy and less ...
WebRecent advances in direct-acting antivirals against Hepatitis C Virus (HCV) have led to the development of potent inhibitors, including MK-5172, that target the viral NS3/4A protease with relatively low susceptibility to resistance. MK-5172 has a P2–P4 macrocycle and a unique binding mode among current protease inhibitors where the P2 quinoxaline packs … WebHCV infection is considered a silent epidemic because most people infected do not develop acute symptoms. Instead, the disease progresses to a chronic state leading to cirrhosis and hepatocarcinoma. Novel therapies are needed to combat this major health threat. The HCV NS3 serine protease has been the target of continuous investigation because of its …
WebA substrate envelope-guided design strategy is reported for improving the resistance profile of HCV NS3/4A protease inhibitors. Analogues of 5172-mcP1P3 were designed by incorporating diverse quinoxalines at the P2 position that predominantly interact with the invariant catalytic triad of the protease.
