inhibitors, identified by pharmacophore screening. We report the identification and validation of 3‐((2‐methoxynaphthalen‐1‐yl)methyl)‐7‐((pyridin‐3‐ylmethyl)amino)‐5,6,7,8‐tetrahydrobenzo[4,5]thieno[2,3‐d]pyrimidin‐4(3H)‐one (ICL‐SIRT078), a substrate‐competitive SIRT2 inhibitor with a Ki value of 0.62±0.15 μM and more than 50‐fold selectivity against SIRT1, 3 and 5.

Sirtuins是NAD +依赖性的组蛋白脱乙酰基酶(HDAC),最近已成为治疗多种疾病的潜在治疗靶标。该酶家族有效和异构体选择性抑制剂的发现应提供化学工具,以帮助确定这些靶标的作用并验证其治疗价值。在本文中,我们报告了通过药效基团筛选确定的一类新型的高选择性SIRT2抑制剂的发现。我们报告了3-((2-甲氧基萘-1-基)甲基)-7-((吡啶-3-基甲基)氨基)-5,6,7,8-四氢苯并[4,5]噻吩的鉴定和验证[2,3 - d ]嘧啶-4(3 H)-one(ICL-SIRT078),一种具有K i的底物竞争性SIRT2抑制剂的0.62±0.15的值μ中号和超过针对SIRT1,3和5用ICL-SIRT078导致α微管蛋白,已建立的SIRT2生物标志物的高乙酰治疗MCF-7乳腺癌细胞的50倍的选择性,在剂量具有可比生化IC 50数据,同时在较高浓度下抑制MCF-7增殖。与最近的报道表明SIR
