Description: CPI203, also known as TEN010, JQ-2; RO6870810 and RG6146, is a potent and orally active BET bromodomain inhibitor. CPI203 enhances the antiproliferative effects of rapamycin on human neuroendocrine tumors. CPI203 ownregulates Myc expression, causes G1 cell cycle arrest and attenuates cell proliferation in human pancreatic neuroendocrine tumors. CPI203 arrests the growth of T cell acute lymphoblastic leukemia cells in vitro (EC50 = 91.2 nM).

Additional Information

TEN-010 binds to the acetylated lysine recognition motifs found in the bromodomain of BET proteins, which prevents the interaction between BET proteins and acetylated histones. This interaction disrupts chromatin remodeling and gene expression. Prevention of the expression of certain growth-promoting genes may lead to an inhibition of tumor cell growth.
