为了寻找更好的抗肿瘤化合物, 基于前期计算机辅助药物设计结果, 以L-色氨酸和甲醛为原料, 经过Pictet-Spengler缩合和氧化两步反应得到β-咔啉, 再经过N9-烷基化反应和N2-烷基化反应得到一系列新的β-咔啉衍生物. 合成的14个新的β-咔啉衍生物的结构经1H NMR, IR, MS及元素分析确证结构. 利用单晶X射线衍射法测定了化合物5h的晶体结构. 采用MTT法考察其对肿瘤细胞的抑制作用, 实验结果表明化合物5a~5n与先导物4相比具有明显的抗肿瘤活性; 用抑瘤率测定了化合物5e和5h对小鼠Lewis肺癌细胞的抑制作用, 体内试验表明化合物5h具有抗Lewis肺癌作用.

In search of more effective antitumor agents, based on the previous results of computer aided drug design. The starting material L-tryptophan reacted with formaldehyde via Pictet-Spengler condensation and followed by oxidation and decarboxylation to afford the intermediate β-carboline. The intermediate was further reacted with halogenated hydrocarbon by N9-alkylation and N2-quaternarization to obtain new β-carboline derivatives. Fourteennovel β-carboline derivatives were synthesized and characterized by 1H NMR, IR, MS and elemental analysis. Compound 5h was further studied by X-ray single crystal diffraction analysis. The antitumor activity of the target compounds was studied by MTT method. The results demonstrated that N2-quaternarized compounds (5a~5n) had more remarkable cytotoxic activities in vitro than 9-phenylpropyl-β-carboline (4). The tumor inhibition rates of the selected compounds 5e and 5h in mice bearing Lewis lung cancer. The compound 9 showed inhibition activity on transplanting-tumor growth of Lewis lung cancer.
