摘要

摘要: 基于本课题组前期工作基础，在天然产物去氢骆驼蓬碱（harmine）的C⁷位氧上引入环己基甲基，并在N⁹位上通过不同长度的烷基链偶联甲基2-氨基-β-D-葡萄糖苷，设计并合成了8个去氢骆驼蓬碱糖基偶联物（14a ~ 14h）。体外抗肿瘤活性筛选和构效关系研究发现，偶联物的抗肿瘤活性随连接臂中烷基链长度的延长而增加。化合物14h对MDA-MB-231乳腺癌细胞的增殖抑制活性显著优于去氢骆驼蓬碱。与去氢骆驼蓬碱相比，糖基的引入改善了化合物14h的水溶性，并通过Warburg效应提高了化合物14h的肿瘤细胞选择性。机制研究发现化合物14h可诱导MDA-MB-231细胞凋亡和G₀/G₁期细胞阻滞，并能通过干扰细胞上皮-间充质转化进程抑制肿瘤细胞迁移。本研究为基于去氢骆驼蓬碱的抗肿瘤药物的开发提供了新思路。

Abstract: Based on our previous work, the study herein designed and synthesized eight glycoconjugates of natural product harmine (14a-14h)by introducing a cyclohexylmethyloxyl group at its C⁷ position and coupling a methyl-2-amino-β-D-glucopyranoside to the N⁹ position through different lengths of alkyl chains.In vitro anti-tumor activity screening and structure-activity relationship studies showed that the antitumor activity of the conjugates increased with the lengthening of the alkyl chain in the linker.Compound 14h exhibited significantly better proliferative inhibitory activity against MDA-MB-231 breast cancer cells than harmine.As compared to harmine, the introduction of the carbohydrate moiety improved the water solubility of compound 14h and enhanced its tumor cell selectivity through the Warburg effect.Mechanism of action studies revealed that compound 14h induced apoptosis and G0/G1 cell cycle arrest in MDA-MB-231 cells, and inhibited tumor cell migration by interfering with epithelial-mesenchymal transition process.This study provides a new approach for the development of antitumor drugs based on harmine.
