Allocolchicinoids, with a distinct polyoxygenated dibenzocycloheptane skeleton, attract much attention as potential candidate anticancer drugs. In this study, eight C-ring fluorinated analogues of allocolchicinoids, seven C-ring oxygen-substituted analogues, and known compounds N-acetylcolchinol and NSC 51046 were synthesized as racemates from a single common intermediate by using either the deoxy
别秋水仙素类化合物具有独特的多氧化二苯并环庚烷骨架,作为潜在的候选抗癌药物备受关注。在这项研究中,通过使用脱氧氟化/迁移多米诺反应或从单一的常见中间体合成了 8 种别秋水仙素的 C 环氟化类似物、7 种 C 环氧取代类似物和已知化合物 N-乙酰秋水仙酚和 NSC 51046 作为外消旋物。酸促进迁移是关键步骤。在获得的产品中,一些氟化衍生物强烈抑制前列腺 DU145 和胰腺 Panc 1 癌细胞系的生长,其功效与 N-乙酰秋水仙醇和 NSC 51046 相当或更好。它们对非癌性肿瘤的毒性也较低细胞系比已知的化合物。
