Bromodomain and extra-terminal (BET) is a promising therapeutic target for various hematologic cancers. We used the BRD4 inhibitor compound 13 as a lead compound to develop a variety of compounds, and we introduced diverse groups into the position of the compound 13 orienting toward the ZA channel. A series of compounds (14–23, 38–41, 43, 47–49) bearing triazolopyridazine motif exhibited remarkable
Bromodomain and extra-terminal (BET) 是各种血液癌症的有希望的治疗靶点。我们使用BRD4抑制剂化合物13作为先导化合物开发了多种化合物,我们在化合物13朝向ZA通道的位置引入了不同的基团。的一系列化合物的(14-23,38-41,43,47-49)轴承三唑并哒嗪基序表现出显着的BRD4蛋白抑制活性。其中,化合物39抑制BRD4(BD1)蛋白的IC 50为0.003 μM,优于先导化合物13。同时,化合物39具有 抗 U266 癌细胞的抗增殖活性,IC 50 = 2.1 μM。另一方面,化合物39可以阻止肿瘤细胞进入G0/G1期并诱导细胞凋亡,这与其抑制细胞增殖的结果一致。生物学和生化数据表明,BRD4 蛋白可能是一个治疗靶点,而化合物39是进一步开发的极好先导化合物。
