Curator's Comment: Description was created based on several sources, including https://www.ncbi.nlm.nih.gov/pubmed/26815195

CPI-0610 is a small molecule inhibitor of the Bromodomain and Extra-Terminal (BET) family of proteins, with potential antineoplastic activity. Upon administration, the BET inhibitor CPI-0610 binds to the acetylated lysine recognition motifs on the bromodomain of BET proteins, thereby preventing the interaction between the BET proteins and acetylated histone peptides. This disrupts chromatin remodeling and gene expression. Prevention of the expression of certain growth-promoting genes may lead to an inhibition of tumor cell growth. CPI-0610 is currently being evaluated in three Phase 1 clinical trials in the U.S.

Sample Use Guides

In Vivo Use Guide

In an ongoing study, CPI-0610 has been administered to patients with progressive lymphoma once daily orally for fourteen consecutive days, followed by a seven-day period without treatment. Cycles are repeated, at escalating doses, as tolerated by the patients. Dosing at three representative levels (24 mg, 120 mg, and 300 mg).

Route of Administration: Oral

In Vitro Use Guide

A panel of MM cell lines was cultured in the presence of increasing doses of CPI-0610 (0-1500 nM) for 72 h. CPI-0610 treatment resulted in dose-dependent cytotoxicity with EC50 ranging between 200 and 900 nM at 72 h for BET-sensitive cell lines (INA6, RPMI-8226, LR5, H929, MM.1S, MM.1R, U266).
