Sirt5 is a potential new drug target for the treatment of cancer, Alzheimer's disease, and Parkinson's disease. Given that norharmane is an important chemical synthon for some biologically important compounds and 9‐substituted norharmane derivatives containing a negatively charged carboxyl group may accord with the characteristic of potential Sirt5 inhibitors, a series of novel 9‐substituted norharmane
Sirt5是治疗癌症,阿尔茨海默氏病和帕金森氏病的潜在新药靶标。鉴于正壬烷是某些生物学上重要的化合物的重要化学合成子,且带有负电荷羧基的9-取代的正壬烷衍生物可能符合潜在的Sirt5抑制剂的特征,因此合成了一系列新颖的9-取代的正烷烷衍生物。所有目标化合物的化学结构和纯度均通过1 H NMR,13 C NMR,MS和HPLC表征。通过体外SIRT5抑制分析,三种化合物(1a,3a和3b)在100 µC浓度下的抑制率均超过30%。M 1和最活泼的化合物3b在30 µ M和100 µ M分别具有35%和52%的抑制率。对接分析表明,化合物3b很可能非常适合Sirt5的底物结合位点,因此,我们认为化合物3b可作为进一步开发特定Sirt5抑制剂的先导化合物。
