The synthesis of a number of structurally related estradiol-17α-ylmethyl hydroxycinnamides and of one novel estra-1,3,5(10),6-tetraen-3-ol-17β-yl hydroxycinnamide is described, using a microwave assisted amidation of steroidal amines with pentafluorophenol activated, non-protected hydroxycinnamic acids as a key step. A selection of the compounds and of other estra-1,3,5(10)-trien-3-ol 17β-yl hydroxycinnamides was screened against 60 human cancer cell lines, derived from nine neoplastic diseases. From the overall results of the screening, it could be inferred that dihydroxycinnamide derived estradiol conjugates exhibit a better cytotoxic profile when compared with hydroxymethoxycinnamide derived estradiol conjugates.
本研究以五氟酚活化的非保护羟基肉桂酸为关键步骤,通过微波辅助酰胺化甾体胺,合成了多种结构相关的雌二醇-17α-基甲基羟基肉桂酰胺和一种新型雌甾-1,3,5(10),6-四烯-3-醇-17β-基羟基肉桂酰胺。针对来自九种肿瘤疾病的 60 种人类癌细胞系,筛选了这些化合物和其他雌甾-1,3,5(10)-三烯-3-醇 17β-yl 羟基肉桂酸。从筛选的总体结果可以推断,与羟甲氧基肉桂烷衍生的雌二醇共轭物相比,二羟基肉桂烷衍生的雌二醇共轭物具有更好的细胞毒性。
