Herein we describe the design and synthesis of a dual active histone deacetylase (HDAC)/bromodomain and extra terminal (BET) small molecule tool inhibitor, DUAL946 (1). Exploiting our extensive epigenetic toolbox, we achieved the functionalisation of a BET active tetrahydroquinoline (THQ) core, with a hydroxamic acid HDAC inhibitor (HDACi) motif. Dual inhibition of BET and HDAC proteins was confirmed
在本文中,我们描述了双重活性组蛋白脱乙酰基酶(HDAC)/溴结构域和额外末端(BET)小分子工具抑制剂DUAL946(1)的设计和合成。利用我们广泛的表观遗传学工具箱,我们实现了具有活泼酸HDAC抑制剂(HDACi)图案的BET活性四氢喹啉(THQ)核心的功能化。通过体外生化和生物物理测试以及细胞裂解物中的化学旋转竞争实验,证实了BET和HDAC蛋白的双重抑制。在免疫细胞和癌细胞中,这种活性都转化为有效的细胞活性。
