Ten ursolic acid derivatives were designed from the lead compound ursolic acid by introducing 1, 2, 3-triazole at C-3 and C-28. The target compounds were synthesized and characterized by 1H NMR and 13C NMR. MTT assay was used to study the antitumor activity of these compounds in human cancer cells with high expression (MCF-7 and SGC-7901). The results showed that the antitumor activity of all compounds on MCF-7 and SGC-7901 tumor cells was significantly higher than that of ursolic acid. The compound 4 exhibited significant antitumor activity which was equivalent to the positive control drug nilotinib, molecular docking showed that the compound 4 have high binding ability with c-Kit, which deserves further research.

以熊果酸为母体, 对其C-3和C-28位进行结构修饰, 引入1, 2, 3-三氮唑, 合成了10个新型熊果酸衍生物, 结构经MS、1H NMR和13C NMR确证。通过MTT法, 选用高表达人癌细胞(乳腺癌MCF-7和胃癌SGC-7901细胞) 对化合物进行初步体外抗肿瘤活性筛选, 结果表明, 所有化合物对MCF-7和SGC-7901肿瘤细胞的抑制活性均明显高于熊果酸。其中化合物4对MCF-7和SGC-7901细胞具有较强的抗肿瘤作用, 活性与阳性对照药尼洛替尼相当, 分子对接也显示其与c-Kit具有较高的结合能力, 值得进一步研究。

以熊果酸为母体, 对其C-3和C-28位进行结构修饰, 引入1, 2, 3-三氮唑, 合成了10个新型熊果酸衍生物, 结构经MS、1H NMR和13C NMR确证。通过MTT法, 选用高表达人癌细胞(乳腺癌MCF-7和胃癌SGC-7901细胞) 对化合物进行初步体外抗肿瘤活性筛选, 结果表明, 所有化合物对MCF-7和SGC-7901肿瘤细胞的抑制活性均明显高于熊果酸。其中化合物4对MCF-7和SGC-7901细胞具有较强的抗肿瘤作用, 活性与阳性对照药尼洛替尼相当, 分子对接也显示其与c-Kit具有较高的结合能力, 值得进一步研究。

Ten ursolic acid derivatives were designed from the lead compound ursolic acid by introducing 1, 2, 3-triazole at C-3 and C-28. The target compounds were synthesized and characterized by 1H NMR and 13C NMR. MTT assay was used to study the antitumor activity of these compounds in human cancer cells with high expression (MCF-7 and SGC-7901). The results showed that the antitumor activity of all compounds on MCF-7 and SGC-7901 tumor cells was significantly higher than that of ursolic acid. The compound 4 exhibited significant antitumor activity which was equivalent to the positive control drug nilotinib, molecular docking showed that the compound 4 have high binding ability with c-Kit, which deserves further research.

Zhen-yu KUAI, Yan-qiu MENG. Synthesis and anti-tumor activity of ursolic acid-triazole derivatives[J]. Acta Pharmaceutica Sinica, 2025 , 60 (1) : 172 -178 . DOI: 10.16438/j.0513-4870.2024-0698
熊果酸(ursolic acid, UA) 别名乌索酸, 是一种天然的乌苏烷型五环三萜类化合物(图 1)。熊果酸具有抗菌、抗病毒、抗肿瘤、抗氧化、治疗糖尿病、保肝等药理活性[1-4]。熊果酸已被公认具有良好的抗肿瘤活性和广泛的抗肿瘤途径[5], 如诱导肿瘤细胞分化及凋亡[6], 抑制肿瘤细胞生成和增殖等[7], 为了改善其水溶性差, 生物利用度低的缺点, 研究人员对熊果酸结构进行修饰, 多集中在C-3位羟基和C-28位羧基[8], 得到的衍生物活性及药动学性质都得到增强和改善。
在药物及天然产物的衍生物设计中, 拼合原理[9]的应用尤具潜力, 即在同一分子中将两种或多种药物的结构或药效团进行拼合, 达到提高相关生物活性或降低毒副作用的效果。含氮唑环作为常见的药物结构活性基团[10], 具有抗炎、抗菌、抗肿瘤等作用[11], 独特结构可与目标靶点结合形成范德华力或氢键等偶极作用, 且化学性质稳定, 作为极性基团也可提高化合物的溶解度从而改善生物利用度[12]。三氮唑基团是唑类基团中热点药效团[13], 具有1, 2, 3-三氮唑和1, 2, 4-三氮唑两种异构体形式, 其中前者的结构具有较强的偶极矩, 作为可能的氢键供给体, 在与靶点结合亲和力方面表现更优[14]。Kim等[15]通过将神经酰胺的酰胺键替换为1, 2, 3-三氮唑, 设计出了具有更高细胞毒性的新型化合物, 一些基于1, 2, 3-三氮唑结构的衍生物也进入临床评估其在癌症治疗中的潜在用途[16]
结合课题组前期利用分子对接技术及化学合成方法对五环三萜化合物的设计和结构修饰研究[17-19], 拼合含氮杂环可提高化合物与靶点蛋白的结合能力, 细胞实验显示相较于母体, 获得了更显著的抗肿瘤活性。本研究在前期工作基础上, 选择在多个恶性肿瘤中具有高表达的Ⅲ型受体酪氨酸激酶(c-Kit) 作为靶点蛋白[20], 将设计出的熊果酸衍生物与受体c-Kit晶体结构(PDB: 1T46) 进行分子对接[21], 以UA为起始原料, 对其C-3位和C-28位分别引入酯键和1, 2, 3-三氮唑结构, 并通过连接碳链的长短初步探究构效关系(图 2)。
为了验证设计合理性, 使用分子对接软件Molegro virtual docker (MVD) 评估目标化合物与c-Kit靶蛋白的结合能力, 目标化合物与蛋白结合均优于母体, 可进行下一步合成。
如合成路线1所示, 以UA为母体, 将1, 2, 3-三氮唑结构分别引入其C-3和C-28位, 设计并合成了10种UA衍生物, 目标化合物1~51~5的收率、熔点、质谱数据列于表 1, 中间体3-1~3-55-1~5-5及目标化合物1~51~51H NMR、13C NMR数据列于表 2
以尼洛替尼[22]为阳性对照, 采用四甲基偶氮唑盐法(MTT法), 在癌细胞(人乳腺癌细胞MCF-7和人胃癌细胞SGC-7901) 中检测熊果酸及其衍生物的抗肿瘤活性, 实验结果见表 3, 化合物4对MCF-7和SGC-7901细胞的IC50值分别为14.28和8.46 μmol·L-1, 接近阳性对照药尼洛替尼, 具有较强的抑制活性。
选择c-Kit抑制剂尼洛替尼和母体熊果酸作对照, 进行分子对接研究, 评分绝对值越大, 结合亲和力越强, 结果如表 4所示。衍生物结构中拼合1, 2, 3-三氮唑结构, 对接得分明显高于母体, 与尼罗替尼相近, 其中化合物4对接得分最高。为了明确化合物4与c-Kit的相互作用情况, 利用Discovery Studio 2019 Client软件, 分析结合位点可能的结合方式(图 3)。化合物4能够进入蛋白的活性口袋, 并与c-Kit蛋白的多个氨基酸残基形成氢键、疏水等相互作用。对比c-Kit抑制剂尼洛替尼的对接结果, 发现二者都与氨基酸残基Asp810形成氢键, 且化合物4连接氢键的为C-28位拼合的1, 2, 3-三氮唑结构, 有文献[23]报道, c-Kit抑制剂能与Asp810产生氢键作用, 推测氨基酸残基Asp810是c-Kit蛋白与抑制剂结合的关键氨基酸。初步判断化合物4和尼洛替尼与靶蛋白具有相同的结合位点。
以UA为母体, 设计并合成了10种UA衍生物, 结构经MS和NMR表征。体外细胞实验表明, 化合物对癌细胞MCF-7和SGC-7901具有抑制作用, 初步的构效关系研究表明, C-3位引入1, 2, 3-三氮唑结构的化合物活性优于C-28位, 且引入碳链的长短会影响衍生物活性, 两类化合物酯键碳数目为5时, 活性最优, 其中化合物4对c-Kit的抑制活性与阳性对照药尼洛替尼相当, 分子对接结果显示化合物中的三氮唑作为酰胺基团的生物电子等排体, 具有提高化合物亲和力的作用, 分析化合物4和尼洛替尼均与Asp810氨基酸残基形成氢键, 具有相同的结合位点。总体而言, UA结构中引入三氮唑结构, 有利于增强其抗肿瘤活性。这对熊果酸进一步结构修饰及优化具有一定的参考意义。
