1‐Alkyl‐2,3,5‐triaryl‐1H‐pyrroles (for which alkyl=methyl, ethyl, n‐propyl, or 2‐methylpropyl) were tested for stability, estrogen receptor (ER) binding, and inhibition of tumor cell growth. These pyrroles (type B) showed higher stability in aqueous solution than their 1,2,4‐triaryl‐1H‐pyrrole congeners (type A pyrroles), exclusive ERα binding (no ERβ interaction), and a hormonal profile of partial
测试了1-烷基-2,3,5-三芳基-1 H-吡咯(烷基=甲基,乙基,正丙基或2-甲基丙基)的稳定性,雌激素受体(ER)结合以及对肿瘤的抑制作用细胞生长。这些吡咯(B型)在水溶液中的稳定性高于其1,2,4-三芳基-1 H-吡咯同类物(A型吡咯),唯一的ERα结合(无ERβ相互作用)和部分激动剂的激素分布。 ERα。最有效的化合物1-(2-甲基丙基)-2,3,5-三(4-羟基苯基)-1 H-吡咯(5 d)的活性低于铅结构1,3,5-tris(用质粒ERE wtc稳定转染的MCF-7细胞中的4-羟基苯基)-4-丙基-1 H-吡唑(PPT)luc(MCF-7 / 2a),但在U2-OS /α细胞中更有效。此外,5 d表现出较弱的抗雌激素特性(IC 50 = 310 n M)。C4处的附加丙基链降低了稳定性和药理作用。
