A series of 1-substituted 1,2,3,4-tetrahydro- and 3,4-dihydro-β-carboline derivatives have been synthesized and evaluated for antitumor activity against murine P-388 and human tumor cell lines, KB-16, A-549 and HT-29. All of the compounds prepared, except for 19, showed significant cytotoxicity. Among them, compound 29 exhibited the most potent activity against all tested tumor cell lines. There was an apparent lack of correlation regarding cytotoxicity between 1,2,3,4-tetrahydro- and 3,4-dihydro-β-carbolines. This study is the first to discover compound 29 as a potential lead for the development of future anticancer agents. The mode of inhibition for compound 29 was proposed.
合成了一系列1-取代的1,2,3,4-四氢-和3,4-二氢-β-卡boline衍生物,并评估了它们对小鼠P-388和人类肿瘤细胞系KB-16、A-549和HT-29的抗肿瘤活性。除化合物19外,所有合成的化合物均表现出显著的细胞毒性。其中,化合物29对所有测试的肿瘤细胞系表现出最强的活性。在1,2,3,4-四氢-β-卡boline和3,4-二氢-β-卡boline之间的细胞毒性并没有明显的相关性。本研究首次发现化合物29作为开发未来抗癌药物的潜在先导。为化合物29提出了抑制机制的假设。
