product name Belnacasan (VX-765)


Description: Belnacasan or VX-765, an orally bioactive prodrug of VRT-043198, is a potent and selective inhibitor of caspase-1 which belongs to the ICE/caspase-1 sub-family caspases.  VX-765 is usually metabolized to an active molecular VRT-043198. In cultures of peripheral blood mononuclear cells stimulated with bacterial products, VRT-043198 inhibited the release of Interleukin (IL)-1β and IL-18, but had no affect the secretion of other cytokines such as IL-α, TNFα, IL-6 and IL-8. This product is also used in other models to illustrate the function of Caspase-1.
