I 类组蛋白脱乙酰酶 (HDAC) 是治疗癌症、炎症、感染和神经系统疾病等一系列疾病的表观遗传疗法的有希望的靶标。尽管六种 HDAC 抑制剂现已获得临床治疗许可,但它们都是泛抑制剂,几乎没有或没有 HDAC 异构体​​选择性,表现出不良副作用。目前可用的 HDAC 抑制剂的一个主要问题是它们的特异性有限并且针对多种脱乙酰酶。除 HDAC8 外,I 类 HDAC(1、2 和 3)被招募到大型多蛋白复合物中发挥作用。因此,越来越需要开发新的、有希望的、具有同工型或复杂选择性的治疗有效的 HDAC 抑制剂。在这里,在介绍I类HDAC及其复合物的结构的基础上,我们提供了基于结构的I类HDAC抑制剂发现的最新概述,包括泛选择性、亚型选择性和复合物特异性抑制剂,旨在深入了解其他具有更高选择性、特异性和治疗效用的HDAC抑制剂的发现。
Class I histone deacetylases (HDACs) are promising targets for epigenetic therapies for a range of diseases such as cancers, inflammations, infections and neurological diseases. Although six HDAC inhibitors are now licensed for clinical treatments, they are all pan-inhibitors with little or no HDAC isoform selectivity, exhibiting undesirable side effects. A major issue with the currently available HDAC inhibitors is that they have limited specificity and target multiple deacetylases. Except for HDAC8, Class I HDACs (1, 2 and 3) are recruited to large multiprotein complexes to function. Therefore, there are rising needs to develop new, hopefully, therapeutically efficacious HDAC inhibitors with isoform or complex selectivity. Here, upon the introduction of the structures of Class I HDACs and their complexes, we provide an up-to-date overview of the structure-based discovery of Class I HDAC inhibitors, including pan-, isoform-selective and complex-specific inhibitors, aiming to provide an insight into the discovery of additional HDAC inhibitors with greater selectivity, specificity and therapeutic utility.
