CZL-077

CZL-077 is a potent, highly selective, and orally active p300/CBP bromodomain (BRD) inhibitor, with p300 IC50 at 0.034 μM and CBP IC50 at 0.052 μM, demonstrating strong selectivity for the BRD of BET proteins (BRD2/3/4) . This compound effectively inhibits the growth of OPM-2 and 22RV1 cells, with IC50 values of 0.024 μM and 5.6 μM, respectively. In xenograft mouse models of OPM-2 and 22RV1, CZL-077 exhibits anti-tumor activity. CZL-077 is applicable for research in multiple myeloma and prostate cancer.
