| General tips | Please select the appropriate solvent to prepare the stock solution according to the solubility of the product in different solvents; once the solution is prepared, please store it in separate packages to avoid product failure caused by repeated freezing and thawing.Storage method and period of the stock solution: When stored at -80°C, please use it within 6 months; when stored at -20°C, please use it within 1 month. |
To increase solubility, heat the tube to 37°C and then oscillate in an ultrasonic bath for some time. | |
| Shipping Condition | Evaluation sample solution: shipped with blue ice. All other sizes available: with RT, or with Blue Ice upon request. |
It has been reported that among bromodomain-containing proteins implicated in various disease pathways, cyclic-AMP response element binding protein (CBP) and adenoviral E1A binding protein of 300 kDa (EP300), which is a highly homologous pair of bromodomain-containing transcriptional coactivators, are of great interest as potential drug targets due to their reported involvement in a variety of disease states.
In vitro: Previous study found that CPI-637 was potent against EP300, and its opposite enantiomer showed a over 200-fold loss in potency. Moreover, the biochemical potency of CPI-637 translated well into cells with CBP BRET EC50 of 0.3 μM, and CPI-637 demonstrated a more than 700-fold selectivity over the BET family of bromodomains. In addition, CPI-637 was also highly selective against other bromodomains, showing substantial biochemical activity only against BRD9. Furthermore, it was found that CPI-637 was able to inhibit the expression of MYC with an EC50 of 0.60 μM in a cellular assay,. [1].
In vivo: So far, there is no animal in vivo data reported.
Clinical trial: Up to now, CPI-637 is still in the preclinical development stage.
