  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，

  A series of novel β-carboline derivatives was designed, synthesized and evaluated as potential anticancer agents. Among them, compound 6g showed the most potent antiproliferative activity against the 786–0, HT-29 and 22RV1 cell lines with IC50 values of 2.71, 2.02, and 3.86 μM, respectively. The antitumor efficiency of compound 6g in vivo was also evaluated, and the results revealed that compound 6g

  To further our SAR study on the chemistry and antitumor activity/neurotoxicity of beta-carboline alkaloids. several series of beta-carboline derivatives with various substituents were designed and synthesized from the starting material L-tryptophan on the basis of harmine chemical structure. Cytotoxic activities of these compounds were investigated in vitro. The results showed that some beta-carboline derivatives had significant cytotoxic activities against human tumor cell lines. Among all the synthesized beta-carboline derivatives, the compounds 27, 28 and 32, having a benzyl substituent at both position-2 and 9, respectively, were found to be the most potent compounds with IC50 value lower than 50 mu M against all human tumor cell lines examined. Acute toxicities and antitumor activities of the selected beta-carboline derivatives in mice were also evaluated. The results demonstrated that a benzyl substituent at position-2 increased the antitumor activity as well as acute toxicity significantly. However an (ethoxycarbonyl)amino substituent at position-3 reduced the acute toxicity as well as antitumor activity remarkedly. These data suggested that (1) the antitumor potencies of beta-carboline derivatives were enhanced by the introduction of benzyl substituent into the position-2; (2) the acute toxicity of beta-carboline derivatives reduced dramatically by the introduction of an appropriate substituent into the position-3 and 9; (3) the beta-carboline structure might be an important basis for the design and synthesis of new antitumor drugs with significant antitumor activity and low toxicity.
