Although HAT1 has been linked to various disease states, no inhibitors have been reported to target HAT1. Here, we designed a set of peptide-CoA conjugates as bisubstrate inhibitors of HAT1 with submicromolar potency. In particular, the bisubstrate inhibitor H4K12CoA exhibited a low Ki value of 1.1 nM for HAT1. In addition, H4K12CoA was shown to be a competitive inhibitor with respect to both AcCoA and
开发选择性酶抑制剂可以扩展分子工具箱,以研究目标酶的功能和活性。组蛋白乙酰基转移酶1(HAT1)是在1990年代中期发现的首批组蛋白乙酰基转移酶(HAT)酶。但是,与其他HAT相比,它仍然是研究不足的酶之一。尽管HAT1已与多种疾病相关,但尚无抑制剂靶向HAT1的报道。在这里,我们设计了一套肽-CoA偶联物作为具有亚微摩尔效能的HAT1的双底物抑制剂。特别地,双底物抑制剂H4K12CoA对HAT1表现出1.1 KiM的低Ki值。此外,相对于AcCoA和H4肽,H4K12CoA被证明是竞争性抑制剂,表明HAT1催化的独特动力学机制。
