We have recently reported that the ferrocenyl diphenol compound 1,1-di(4-hydroxyphenyl)-2-ferrocenyl-but-1-ene 1 exhibited strong in vitro anti-proliferative effects on both hormone dependent (MCF7, IC50 = 0.7 μM) and hormone independent (MDA-MB231, IC50 = 0.6 μM) breast cancer cells. In order to assess the importance of the ferrocenyl motif, we have prepared a series of analogs using the organometallic
我们最近报道,二茂铁基二酚化合物1,1-二(4-羟基苯基)-2-二茂铁基-丁-1-烯1对两种激素依赖性化合物均具有很强的体外抗增殖作用(MCF7,IC 50 = 0.7μM )和激素非依赖性(MDA-MB231,IC 50 = 0.6μM)乳腺癌细胞。为了评估所述二茂铁基序的重要性,我们准备了使用有机金属片段的一系列类似物的(η 5 -C 5 H ^ 4)的Cp *的Fe(7),((η 5 -C 5 H ^ 4)(CH 3)2磷酰基)Fe(9),(η5 -C 5 H ^ 4)CPRU(10),(η 5 -C 5 H ^ 4)的Re(CO)3(11),和(η 5 -C 5 H ^ 4)的Mn(CO)3(12),和氯化二茂铁基衍生物1,1-二(4-羟苯基)-2-二茂铁基-4-氯丁-1-烯(4)。有机金属部分的性质对雌激素受体α(ERα)的识别有很大的影响,相对结合亲和力(RBA)值的范围从0
