Several newly synthesized delcosine derivatives (6, 7, 13, 13a, 13b) showed substantial suppressive effects against all human tumor cell lines tested. In contrast, the natural alkaloids (1, 31, 33) showed no effect. Most of the active compounds were delcosine derivatives with two specific substitution patterns—C-1 and C-1,14. In particular, 1-acyldelcosine derivative (5–7) displayed more potency than 1,14-diacyldelcosine
具有明显化学性质和生物活性的二萜类生物碱经常在乌头,翠雀和Garrya属植物中发现。但是,关于乌头和雀花植物的二萜类生物碱成分的抗增殖作用的报道很少。C-1和delcosine 14个酯化(1)中进行,以提供39个新二萜生物碱衍生物(3 - 14,16 - 29,图3a -图7a,图9A,图13A,13B,14a,14b,16a,17a,24a,35a)。选择的化合物(3 - 14,16 - 29,图3a -图7a,图9A,图13A,13B,14A,14B,16A,17A,24A,35A)评估了针对三到五种人类肿瘤细胞系的抗增殖活性,这些细胞系包括三阴性乳腺癌(TNBC)和过表达多药耐药性(MDR)的P-糖蛋白(P-gp)。几个新合成delcosine衍生物(6,7,13,13A,13B)显示对测试的所有人类肿瘤细胞系显着抑制效果。相反,天然生物碱(1,31,33)显示没有影响。大多数活性
