the method allowed functional group compatibility towards hydroxyl tether, displaying exquisite chemoselectivity. All the synthesized compounds were screened for their tumor cell growth inhibitory activity against human cervix adenocarcinoma (HeLa). Compound 7d emerged as the most active (IC50 = 0.69 μM) among the tested series compared to the standard cis-platin (IC50 = 0.08 μM).
本文报道的是金(III)催化的2-炔基-吲哚-3-羧酸的6-内-挖环异构化反应,形成吡喃并[4,3 - b ]吲哚-1(5 H)-一,是药学上重要的结构基序。该方法所需的迄今未知的底物可以方便地分五个步骤合成,且总收率良好。使用一系列底物可获得优异的区域选择性,证明了这种新的环异构化的实用性。该方法的温和性允许官能团与羟基系链相容,显示出出色的化学选择性。筛选所有合成的化合物对人宫颈腺癌(HeLa)的肿瘤细胞生长抑制活性。 与标准顺铂(IC 50 = 0.08μM )相比,化合物7d在测试系列中表现出最高的活性(IC 50 = 0.69μM )。
