I-CBP112是一种特异性和有效的乙酰-赖氨酸竞争性蛋白-蛋白相互作用抑制剂，抑制 CBP/p300 溴结构域，增强 p300 的乙酰化作用。

I-CBP112 is a specific and potent acetyl-lysine competitive protein-protein interaction inhibitor, that inhibits the CBP/p300 bromodomains, enhances acetylation by p300.

Solid

IC50: 5.5±1.1 μM (CBP/p300, Leukemia cell); 9.1±1.2 μM (CBP/p300, Prostate cancer cell)

I-CBP112 significantly enhances acetylation by p300 at the histone H3K18 and H3K23 sites. I-CBP112 stimulated H3K18ac by ~3-fold, I-CBP112 induced enhances acetylation of these same sites by CBP as well as at H4K5. The EC50’s of activation of I-CBP112 on p300- and CBP-mediated H3K18 acetylation are ~2 μM. Exposure of human and mouse leukemic cell lines to I-CBP112 results in substantially impaired colony formation and induces cellular differentiation without significant cytotoxicity. Exposure of the BioMAP primary cell panel to I-CBP112 results in a unique response on cytokine and marker protein expression. has not independently confirmed the accuracy of these methods. They are for reference only.

I-CBP112 significantly reduces the leukemia-initiating potential of mLL-AF9+ AmL cells in a dose-dependent manner in vitro and in vivo. The synergistic effects of I-CBP112 and current standard therapy (doxorubicin) as well as emerging treatment strategies (BET inhibition) provide new opportunities for combinatorial treatment of leukemia and potentially other cancers. has not independently confirmed the accuracy of these methods.
