A series of racemic indole C5-substituted seco-cyclopropylindoline compounds (2,3 and 5–7) were prepared by coupling 1-(tert-butyloxycarbonyl)-3-(chlorocarbonyl)indoline (seg-A) with 5,6,7-trimethoxy-, 5,6-dimethoxy-, 5-amino-, 5-methylsulfonylamino- and 5-(N,N-dimethylaminosulfonylamino) indole-2-carboxylic acid as seg-B in the presence of 1-ethyl-3-(3-dimethylaminopropyl) carbodiimide. The synthetic compounds (2,3 and 5–7) were tested for cytotoxic activity against human cancer cell lines (COLO 205, SK-MEL-2, A549, and JEG-3) using the MTT assay.
在 1-乙基-3-(3-二甲氨基丙基)碳二亚胺的存在下,将 1-(叔丁氧羰基)-3-(氯羰基)吲哚啉(seg-A)与 5,6,7-三甲氧基-、5,6-二甲氧基-、5-氨基-、5-甲磺酰氨基-和 5-(N,N-二甲氨基磺酰氨基)吲哚-2-羧酸(seg-B)偶联制备。采用 MTT 法测试了合成化合物(2、3 和 5-7)对人类癌细胞株(COLO 205、SK-MEL-2、A549 和 JEG-3)的细胞毒性活性。
