Mercaptoacetamide‐based ligands have been designed as a new class of histone deacetylase (HDAC) inhibitors for possible use in the treatment of neurodegenerative diseases. The thiol group of these compounds provides a key binding element for interaction with the catalytic zinc ion, and thus differs from the more typically employed hydroxamic acid based zinc binding groups. Herein we disclose the chemistry
基于巯基乙酰胺的配体已被设计为新型的组蛋白脱乙酰基酶(HDAC)抑制剂,可用于治疗神经退行性疾病。这些化合物的硫醇基团提供了与催化锌离子相互作用的关键结合元素,因此不同于更常用的基于异羟肟酸的锌结合基团。本文中,我们公开了一些取代的巯基乙酰胺的化学和生物学性质,目的是提高HDAC6同工型的选择性,同时保持类似于其异羟肟酸类似物的效价。发现向硫醇基团引入立体中心α对HDAC抑制剂效能具有相当大的影响。
