compounds were evaluated for antiproliferative activities in vitro in a panel of tumor cell lines including those exhibiting resistance to proapoptotic stimuli and representing solid cancers associated with dismal prognoses, such as melanoma, glioblastoma, and non-small-cell lung cancer. Most active analogues were not discriminatory between cancer cells displaying resistance or sensitivity to apoptosis
作为我们旨在开发一种源自石蒜科生物碱石蒜碱的新型细胞抑制剂的研究的延续,我们合成了这种天然产物的 32 种类似物。这组合成类似物包括将 C1 与 C2 羟基选择性衍生化、芳构化环 C、内酰胺化 N6 氮、二羟基化 C3-C3a 烯烃官能团、从 C3-C3a 到 C2-C3 或 C3a-C4 的转置烯烃和 C1 的化合物长链脂肪酸酯。所有合成的化合物都在一组肿瘤细胞系中进行了体外抗增殖活性的评估,这些细胞系包括那些对促凋亡刺激物表现出抗性并代表与预后不良相关的实体癌,如黑色素瘤、胶质母细胞瘤和非小细胞肺癌。大多数活性类似物不能区分对细胞凋亡具有抗性或敏感性的癌细胞,表明这些化合物因此能够克服癌细胞对促凋亡刺激的内在抗性。1,2-Di-O- allyllycorine 被鉴定为一种石蒜碱类似物,其对抗 U373 人类胶质母细胞瘤模型的效力是母体天然产物的 100 倍。此外,许多合成类似物被确定为有希望用于即将进行的体内研究。
