The histone acetyltransferase (HAT) enzymes p300 and CBP are closely related paralogs that serve as transcriptional coactivators. The p300 and CBP catalyze the acetylation of Lys residues in histones and other proteins. Serving as transcriptional coactivators, p300 and CBP participate in numerous ways to regulate cell growth, differentiation, and gene expression across many organ systems and physiologic pathways. Dysregulation of p300/CBP by mutation, altered expression, or other mechanisms has been linked to disease states, including various malignancies such as acute leukemias and prostate cancer. Furthermore, p300/CBP is critical in development as evidenced by the genetic disorder Rubinstein-Taybi syndrome, which occurs with loss of function mutations in single alleles of either p300 or CBP. Inhibitors of p300/CBP HAT activity have been developed and are under investigation as therapeutics for a number of diseases.

A cocrystal structure of CPI-637 in the CBP bromodomain indicated that the compound recapitulated the key hydrogen bonding interactions observed with the parent compound, with the substituted indazole filling space above Pro1110 and the Pro/Arg cleft . As expected, CPI-637 was also potent against EP300, and its opposite enantiomer displayed a >200-fold loss in potency. The biochemical potency of CPI-637 translated well into cells (CBP BRET EC50 = 0.3 μM), and the compound demonstrated a >700-fold selectivity over the BET family of bromodomains (BRD4 IC50 = 11.0 ± 0.6 μM).CPI-637 was also highly selective against other bromodomains (detailed list in the Supporting Information), displaying substantial biochemical activity only against BRD9, which is acceptable, since inhibition of the BRD9 bromodomain has not been shown to produce a pronounced cellular phenotype . In a cellular assay, CPI-637 inhibits the expression of MYC, a transcription factor widely expressed in human cancer,with an EC50 of 0.60 μM, providing an orthogonal measure of the target engagement of the compound .The inactive enantiomer of CPI-637 displayed an EC50 in the same assay of >10 μM.[1]
