CuI facilitated the intramolecular cyclization of 8-alkynyl substituted 2,3-dihydroquinolin-4(1H)-ones leading
to 5-subtituted 2,3-dihydro-1H-pyrrolo[3,2,1-ij]quinolin-1-ones via intramolecular C-N bond forming reaction. Some of
the synthesized compounds have shown encouraging inhibition of Sir 2 protein (a yeast homolog of mammalian SIRT1)
when tested using a yeast cell based assay. A representative compound showed dose dependent inhibition of yeast Sir 2
(IC50 = 30.09 µM) and cell growth inhibition properties when tested against different cancer cell lines. It’s in silico interactions
with sirtuins are presented.
CuI 促进 8-炔基取代的 2,3-二氢喹啉-4(1H)-酮的分子内环化
通过分子内C-N键形成反应生成5-取代的2,3-二氢-1H-吡咯并[3,2,1-ij]喹啉-1-酮。一些
合成的化合物对 Sir 2 蛋白(哺乳动物 SIRT1 的酵母同源物)显示出令人鼓舞的抑制作用
当使用基于酵母细胞的测定法进行测试时。代表性化合物对酵母 Sir 2 具有剂量依赖性抑制作用
(IC50 = 30.09 µM) 和针对不同癌细胞系进行测试时的细胞生长抑制特性。这是计算机交互
与 Sirtuins 一起提出。
