Description: VRT-043198, the active metabolite of VX-765, is a Caspase inhibitor. VRT-043198 exhibits 100- to 10,000-fold selectivity against other caspase-3 and -6 to -9. VRT-043198 inhibited the release of interleukin (IL)-1beta and IL-18, but it had little effect on the release of several other cytokines, including IL-1alpha, tumor necrosis factor-alpha, IL-6 and IL-8.
