T-sCPY-s500R-H is a NADPH-based FRET ratiometric biosensor probe. T-sCPY-s500R-H forms a 1:1 FRET pair upon binding to the eDHFR-HaloTag fusion protein through conjugation of the donor s500R (green fluorescence) and the acceptor sCPY (red fluorescence) with the HaloTag ligand and the eDHFR ligand (TMP), respectively; NADPH binding to eDHFR induces a conformational change that converts sCPY from a colorless spirolactam form to a red fluorescent form, enabling quantification of NADPH levels through the ratio of red/green fluorescence intensity (Ex = 488 or 490 nm; green channel Em = 500-580 nm; red channel Em = 600-700 nm). T-sCPY-s500R-H is applicable to research in fields such as cell metabolism studies, oxidative stress and NADPH homeostasis analysis, tumor metabolism, and NADPH-modulating drug screening .

Hepatitis C virus (HCV) is a hepatotropic enveloped positive- strand RNA virus (family Flaviviridae) that infects the parenchymal cells of the liver. HCV infection is a significant public health burden. Globally, an estimated 71 million people have chronic hepatitis C virus infection. A significant number of those who are chronically infected will develop cirrhosis or liver cancer. To date, there is no vaccine against HCV, and combination pegylated alpha interferon (pIFN-) and ribavirin, the main standard-of-care treatment for HCV, is effective in only a subset of patients and is associated with a wide spectrum of toxic side effects and complications. More recently, new therapeutic approaches that target essential components of the HCV life cycle have been developed, including direct-acting antiviral (DAA) that specifically block a viral enzyme or functional protein and host-targeted agents (HTA) that block interactions between host proteins and viral components that are essential to the viral life cycle. However, the genetic diversity of HCV viruses and the stage of liver disease (i.e., cirrhosis) are revealing themselves as obstacles for effective, pan-genotypic treatments. There still exists a need for the discovery and development of new HCV inhibitors. In particular, since the future of HCV therapy will likely consist of a cocktail approach using multiple inhibitors that target different steps of infection, new antivirals targeting all steps of the viral infection cycle.

MCE offers a unique collection of 394 compounds with identified and potential anti-HCV activity. MCE Anti- Hepatitis C Virus Compound Library is a useful tool for discovery new anti-HCV drugs and other anti-infection research.
