  Synthesis and in vitro cytotoxic evaluation of 1,3-bisubstituted and 1,3,9-trisubstituted β-carboline derivatives

  摘要：

  A series of novel 1,3-bisubstituted and 1, 3,9-trisubstituted beta-carboline derivatives was synthesized from the starting material L-tryptophan. Cytotoxic activities of these compounds were investigated in vitro. The results showed that 1,3,9-trisubstituted beta-carboline derivatives had higher cytotoxic activities in vitro than the corresponding 1,3-bisubstituted compounds. Among all the synthesized 1,3,9-trisubstituted P-carboline derivatives, the compounds with a methyl substituent at position-1 displayed more potent cytotoxic activities, furthermore compound 5e having an ethoxycarbonyl substituent at position-3 and a pentafluorobenzyl at position-9, respectively, was found to be the most potent compounds of this series with IC50 value of 4 uM against BGC-823 cell lines. These data suggested that (1) the cytotoxic potencies of beta-carboline derivatives were enhanced by the introduction of appropriate substituents into position-1 and position-9 in beta-carboline; (2) the beta-carboline structure might be an important basis for the design and synthesis of new antitumor drugs; (3) the methyl substituent at position-1, the pentafluorobenzyl group at position-9 and the ethoxycarbonyl substituent at position-3 were the optimal combination for the improvement of cytotoxic activity of the P-carboline derivatives.

  This research studied the structure-activity relationship of beta-carboline derivatives as antitumor agents, in which 41 synthesized compounds and their cytotoxicity to tumor and normal cell lines were assayed. It was proved that substituent in position-9 of the beta-carboline ring could reinforce the DNA intercalating ability and consequently cytotoxicity to tumor cell lines, and the amidation of

  本研究研究了β-咔啉衍生物作为抗肿瘤剂的构效关系，分析了41种合成化合物及其对肿瘤和正常细胞系的细胞毒性。事实证明，β-咔啉环第9位的取代基可增强DNA的插入能力，从而增强对肿瘤细胞的细胞毒性，而靶向第3位侧链的DNA末端的氨基酰胺化则会削弱这些化合物的DNA嵌入活性，从而引发了对肿瘤细胞系而不是正常细胞系的细胞毒选择性。此外，这些化合物引起的S和G2-M阻滞证实，它们可以靶向DNA并导致Hela细胞中的DNA破坏。简而言之，
