组蛋白去乙酰化酶6(HDAC6)是组蛋白去乙酰化酶家族中独具特色的一员。该酶具有两个去乙酰化功能区,可特异性催化非组蛋白底物,参与并调节众多生理或病理进程。目前已报道的选择性HDAC6抑制剂结构种类较多,有的正处于临床试验阶段。本文将对HDAC6的结构、功能及其选择性抑制剂的研究进展进行综述。
Histone deacetylase 6 (HDAC6) is an unique subtype of histone deacetylases with two tandem deacetylase domains and substrate specificity for non-histone proteins. It is involved in many important physiological and pathological processes and has become a promising therapeutic target in recent decades. Different kinds of potent HDAC6-selective inhibitors have been reported around the world. This paper reviews the progress in the study of structure and functions of HDAC6 as well as the development of HDAC6-selective inhibitors.
