CPI-203

CPI-203 is an orally available derivative of triazolothienodiazepine JQ-1; it exhibits no sedative or anxiolytic efficacy and is currently in development as a potential anticancer compound. Like JQ-1, CPI-203 inhibits the BET bromodomain (BRD) family of proteins, including BRD4; inhibition of this protein downregulates Myc expression and IL-6 production in vitro. This compound also inhibits phosphorylation of the carboxyl-terminus domain of RNA polymerase II.
