A series of hydroxamic acid derivatives bearing a cyclic amide/imide group as a linker and/or cap structure, prepared during our structural development studies based on thalidomide, showed class-selective potent histone deacetylase (HDAC)-inhibitory activity. Structure-activity relationship studies indicated that the steric character of the substituent introduced at the cyclic amide/imide nitrogen
在我们根据沙利度胺进行的结构开发研究中制备的一系列带有环状酰胺/酰亚胺基团作为连接基和/或帽结构的异羟肟酸衍生物显示出对类组有效的组蛋白脱乙酰基酶(HDAC)的抑制活性。结构-活性关系研究表明,在环状酰胺/酰亚胺氮原子上引入的取代基的空间特征,酰胺/酰亚胺羰基的存在,异羟肟酸的结构,连接基团的形状以及它们之间的距离结合锌的异羟肟酸基团和帽结构对于抑制HDAC的活性和类别选择性都很重要。具有代表性的化合物(30w)显示出强效的p21启动子活性,与曲古抑菌素A(TSA)相当,
