experimental binding affinity results for compounds 2, 2 a, 2 b, 5, 5 a, and 5 b. Electrochemical experiments show that 1–4, 2 a, and 2 b are stable to oxidation on the electrochemical timescale, unlike 5, 5 a, and 5 b, and that cytotoxicity is related to less positive phenol oxidation potentials. The SAR study shows that the presence of a ketone group and two phenol groups is necessary for strong receptor
我们在此报告乳腺癌药物他莫昔芬衍生物的合成和细胞增殖特性,其中负责该药物抗雌激素特性的O(CH 2)2 N(CH 3)2侧链已被α二茂铁基部分。我们最近报道的二酚化合物5,其中该氨基酸链已被替换为酰基二茂铁( O(CH 2)2 C(O)[(η 5 -C 5 H ^ 4)(FeCp])组,并且对激素依赖性MCF-7和非依赖性MDA-MB-231乳腺癌细胞系均具有抗增殖作用。现在,我们报告结构-活性关系(SAR)研究的结果,其中侧链长度已变化,酮基已被省略,苯酚基团的数目已变化。化合物1 - 4,具有侧链缺乏羰基函数( O(CH 2)Ñ [(η 5 -C 5 H ^ 4)FeCp],Ñ= 1–4),并且随着链长的增加,其对ERα的亲和力降低(ER =雌激素受体),对MCF-7细胞起雌激素作用,对PC-3前列腺癌细胞起轻度细胞毒性作用,IC 50值约为10 μ中号。的两个单酚类衍生物2,2
