摘要: 对熊果酸C28位与C3位进行结构修饰得到了24个衍生物, 并利用 1H NMR, 13C NMR, MS及HR-MS对这些化合物进行了结构表征. 进一步通过MTT法, 以内皮细胞HUVEC为主要模型, 研究了24个衍生物抗肿瘤血管生成的活性, 同时以A549, Bel-7402及MCF-7细胞为模型研究了上述衍生物对肿瘤细胞的抑制活性. 研究结果表明, 与熊果酸相比, 化合物5, 9, 12e和14e对HUVEC细胞有较好的选择性, 化合物12a和13h比熊果酸的抗肿瘤血管生成活性略高, 因此通过适当改变熊果酸C28位的结构可以提高其对内皮细胞HUVEC的选择性, 增强抗肿瘤血管生成活性. 本文结果表明, 熊果酸及其衍生物是潜在的具有抗肿瘤血管生成作用的先导化合物, 通过有效的结构优化可能得到新型的抗肿瘤血管生成的化合物.

Abstract: Twenty-four derivatives of ursolic acid modified at C3 and C28 were designed and synthesized for the investigation of the structure-activity relationship of ursolic acid(1) against angiogenesis. All the compounds were characterized by 1H NMR, 13C NMR, MS and HR-MS. HUVEC was used as an angiogenesis target cell and A549, Bel-7402 and MCF-7 were as cancer target cells and the antiproliferative activity was assayed by MTT method. The results show that compounds 5, 9, 12e and 14e possess the selectively antiproliferative activity of HUVEC, meanwhile, compounds 12a and 13h are more active than compound 1 against the proliferation of HUVEC. Therefore, it is possible that more potent and selective angiogenesis inhibitors of ursolic acid derivatives could be discovered by suitable modification at C28 position of ursolic acid. These data suggest that ursolic acid and its derivatives represent a promising lead structural core to discover a new class of antiangiogenesis agents.
