Kinase experiment: | Proteins are buffered in 10 mM HEPES, pH 7.5, 500 mM NaCl and assayed in a 96-well plate at a final concentration of 2 μM in 20 μL volume. Compounds (TPOP146) are added at a final concentration of 10 μM. SYPRO Orange (Molecular Probes) is added as a fluorescence probe at a dilution of 1:1000. Excitation and emission filters for the SYPRO Orange dye are set to 465 and 590 nm, respectively. The temperature is raised with a step of 3°C per minute from 25 to 96°C, and fluorescence readings are taken at each interval[1]. |

TPOP146 is a selective CBP/P300 benzoxazepine bromodomain inhibitor with Kd values of 134 nM and 5.02 μM for CBP and BRD4.
Exposure to 1 μM TPOP146 results in a significant decrease of recovery half-life that is comparable to the construct that contained the bromodomain inactivating mutation N1168F, demonstrating that TPOP146 targets the CBP bromodomain in the nucleus and is capable of competing with acetyl-lysine mediated interactions of the CBP bromodomain in cellular environments[1].

Development of Selective CBP/P300 Benzoxazepine Bromodomain Inhibitors
J Med Chem 2016 Oct 13;59(19):8889-8912.PMID:27673482DOI:10.1021/acs.jmedchem.6b00774
CBP (CREB (cAMP responsive element binding protein) binding protein (CREBBP)) and P300 (adenovirus E1A-associated 300 kDa protein) are two closely related histone acetyltransferases (HATs) that play a key role in the regulation of gene transcription. Both proteins contain a bromodomain flanking the HAT catalytic domain that is important for the targeting of CBP/P300 to chromatin and which offeres an opportunity for the development of protein-protein interaction inhibitors. Here we present the development of CBP/P300 bromodomain inhibitors with 2,3,4,5-tetrahydro-1,4-benzoxazepine backbone, an N-acetyl-lysine mimetic scaffold that led to the recent development of the chemical probe I-CBP112. We present comprehensive SAR of this inhibitor class as well as demonstration of cellular on target activity of the most potent and selective inhibitor TPOP146, which showed 134 nM affinity for CBP with excellent selectivity over other bromodomains.
