Owing to its presence in several biological processes, Sirt1 acts as a potential therapeutic target for many diseases. Here, we report the structure-based designing and synthesis of two distinct series of novel Sirt1 inhibitors, benzimidazole mono-peptides and amino-acid derived 5-pyrazolyl methylidene rhodanine carboxylic acid. The compounds were evaluated for in vitro enzyme-based and cell-based
由于 Sirt1 存在于多种生物过程中,它可作为许多疾病的潜在治疗靶点。在这里,我们报告了两个不同系列的新型 Sirt1 抑制剂、苯并咪唑单肽和氨基酸衍生的 5-吡唑基亚甲基绕丹宁羧酸的基于结构的设计和合成。对这些化合物进行了体外基于酶和基于细胞的 Sirt1 抑制测定以及在肝癌和乳腺癌细胞中的细胞毒活性的评估。色氨酸缀合物即13h (IC 50 = 0.66 μM, Δ G bond = -1.1 kcal mol -1 ) 和7d (IC 50 = 0.77 μM, Δ G bond = -4.4 kcal mol -1 ) 证明了抑制 Sirt1 的最大功效。 MD 模拟揭示,在基于细胞的测定中,通过新基序“SLxVxP(V/F)A”在底物结合位点处的静电互补性可能是 Sirt1 抑制比 Sirt2 增加13h和13l的原因。控制 Ex527 和7d 。最后,这项研究重点介绍了新分子7d和13h
