Novel N-indolylmethyl substituted spiroindoline-3,2′-quinazolines were designed as potential inhibitiors of SIRT1. These compounds were synthesized in good yields by using Pd/C–Cu mediated coupling-cyclization strategy as a key step involving the reaction of 1-(prop-2-ynyl)-1′H-spiro[indoline-3,2′-quinazoline]-2,4′(3′H)-dione with 2-iodoanilides. Some of the compounds synthesized have shown encouraging
新型的N-吲哚基甲基取代的螺吲哚啉-3,2'-喹唑啉被设计为SIRT1的潜在抑制剂。通过使用Pd以良好的收率合成这些化合物/ C-铜介导的偶联环化策略为涉及1-(丙-2-炔基)的反应中的关键步骤-1' ħ -螺[二氢吲哚3,2'-喹唑啉] -2,4-'(3' ħ)-二碘苯胺与二碘代苯胺 合成的某些化合物在体外显示出对Sir 2蛋白(哺乳动物SIRT1的酵母同系物)的令人鼓舞的抑制作用,其中三个对Sir 2具有剂量依赖性的抑制作用。对接结果表明,1,2,3,这些分子的4-四氢喹唑啉环系统占据了蛋白质的深疏水口袋,并且NH之一与磺酰基一起参与了与氨基酸残基的强H键相互作用。
