We have identified a proteolysis targeting chimera (PROTAC) of class I HDACs 1, 2 and 3. The most active degrader consists of a benzamide HDAC inhibitor, an alkyl linker, and the von Hippel-Lindau E3 ligand. Our PROTAC increased histone acetylation levels and compromised colon cancer HCT116 cell viability, establishing a degradation strategy as an alternative to class I HDAC inhibition.
我们鉴定了一个靶向 I 类组蛋白去乙酰化酶(HDACs)1、2 和 3 的蛋白水解靶向嵌合体(PROTAC)。最有效的降解物由苯甲酰胺 HDAC 抑制剂、烷基连接子和 von Hippel-Lindau E3 配体组成。我们的 PROTAC 增加了组蛋白乙酰化水平并损害结肠癌细胞 HCT116 的活力,建立了一种降解策略,作为 I 类 HDAC 抑制的替代方案。
