acid as the zinc binding group (ZBG) have been the most effective histone deacetylase inhibitors (HDACi) to date. However, concerns about the pharmacokinetic liabilities of the hydroxamic acid moiety have stimulated research efforts aimed at finding alternative nonhydroxamate ZBGs. We have identified 3-hydroxypyridin-2-thione (3-HPT) as a novel ZBG that is compatible with HDAC inhibition. 3-HPT inhibits
带有异羟肟酸作为锌结合基团 (ZBG) 的小分子是迄今为止最有效的组蛋白脱乙酰酶抑制剂 (HDACi)。然而,对异羟肟酸部分的药代动力学特性的担忧刺激了旨在寻找替代非异羟肟酸酯 ZBG 的研究工作。我们已将 3-羟基吡啶-2-硫酮 (3-HPT) 鉴定为与 HDAC 抑制相容的新型 ZBG。3-HPT 抑制 HDAC 6 和 HDAC 8,IC 50 分别为 681 和 3675 nM。值得注意的是,3-HPT 对 HDAC 1 没有抑制作用。随后的优化产生了几种新型的基于 3HPT 的 HDACi,它们对 HDAC 6 和 HDAC 8 具有选择性。此外,这些抑制剂的一个子集在各种癌细胞系中诱导细胞凋亡。
