domains. However, the reported synthesis route of XY153 and its derivatives are extremely poor-yielding. After the synthesis of three key fragments, XY153 can only be obtained with a yield of 1.3 % in the original four-step reaction. In this study, we reported a three-step alternative route in the synthesis process of XY153. The reaction conditions for this route were thoroughly investigated and optimized
XY153 是一种很有前景的 BET BD2
抑制剂,针对 BR
D4 BD2 的 IC 50值为 0.79 nM。它的选择性是 BR
D4-BD1 的 354 倍,是其他 BET BD2 结构域的 6 倍。然而,已报道的XY153及其衍
生物的合成路线收率极差。三个关键片段合成后,原来的四步反应只能得到XY153,收率仅为1.3%。在这项研究中,我们报告了 XY153 合成过程中的三步替代路线。该路线的反应条件经过彻底研究和优化,产率显着提高至 61.5%。这种高效的合成路线为在不久的将来快速合成 XY153 衍
