Abstract16-(1-R-1,2,3-Triazol-4-ylethyl)-, 16-(1-R-1,2,3-triazol-4-ylmethoxymethyl)-, and 16-2-(1-R-1,2,3-triazol-4-yl)-1-[(1-R-1,2,3-triazol-4-ylmethoxy)ethyl]}-substituted derivatives of methyl lambertianate were synthesized by 1,3-cycloaddition of labdanoid alkynes with azides. The compounds obtained possess considerable cytotoxicity toward the human tumor cell lines CEM-13, MT-4, and U-937. The
摘要 16-(1-R-1,2,3-Triazol-4-ylethyl)-, 16-(1-R-1,2,3-triazol-4-ylmethoxymethyl)-, 和 16-2-(1 -R-1,2,3-三唑-4-基)-1-[(1-R-1,2,3-三唑-4-基甲氧基)乙基]}-取代的朗伯坦酸甲酯衍生物由1,劳丹醇炔烃与叠氮化物的 3-环加成反应。获得的化合物对人肿瘤细胞系 CEM-13、MT-4 和 U-937 具有相当大的细胞毒性。发现最活跃的化合物 16-(2-2-[(1-benzyl-1H-1,2,3-triazol-4-yl)acetyl]furan-3-yl}ethyl)lambertianate 可抑制在 7–12 μmol L−1 的浓度下,肿瘤细胞的活力增加了 50% (CCID50)。
