  Investigations on Estrogen Receptor Binding. The Estrogenic, Antiestrogenic, and Cytotoxic Properties of C2-Alkyl-Substituted 1,1-Bis(4-hydroxyphenyl)-2-phenylethenes

  摘要：

  C2-Alkyl-substituted 1,1-bis(4-hydroxyphenyl)-2-phenylethenes were synthesized and assayed for estrogen receptor binding in a competition experiment with radiolabeled estradiol ([H-3]-E-2) using calf uterine cytosol. The relative binding affinity decreased with the length of the side chain R = H (3a: 35.2%) > Me (3b: 32.1%) > Et (3c: 6.20%); CH2CF3 (3d: 5.95%) > n-Pr (3e: 2.09%) > Bu (3f: 0.62%). Agonistic and antagonistic effects were evaluated in the luciferase assay with MCF-7-2a cells stably transfected with the plasmid ERE(wtc)luc. All compounds showed high antiestrogenic activity without significant agonistic potency. The comparison of the IC50 values for the inhibition of E2 (1 nM) documented the dependence of the antagonistic effects on the kind of the side chain: 3a (IC50 = 150 nM), 3b (IC50 = 30 nM), and 3f (IC50 = 500 nM) were weak antagonists, while 3c (IC50 = 15 nM), 3d (IC50 = 9 nM), and 3e (IC50 = 50 nM) were full antiestrogens and antagonized the effect of E2 completely. The most active compound 3d possessed the same antagonistic potency as 4-hydroxytamoxifen (40HT: IC50 = 7 nM) without bearing a basic side chain. 3d as well as all other 1,1-bis(4-hydroxyphenyl)-2-phenylalkenes were not able to influence the proliferation of hormone dependent MCF-7 cells despite the antagonistic mode of action. In this assay tamoxifen (TAM) and 40HT reduced the cell growth concentration dependent up to T/C-corr = 15% and 25%, respectively.

  The reactions of chiral benzyl carbocations bearing alpha-phenyl substituents with N-sulfonylated indoles afford 1,1,2-triarylalkanes with anti-selectivities. This outcome is a reversal of facial diastereoselectivity relative to Bach's alpha-alkyl-bearing benzyl cations. The reactions are promoted by either a Bronsted acid (TFA) or Lewis acid (BF3.OEt2), offering differential diastereoselectivities

  带有α-苯基取代基的手性苄基碳阳离子与N-磺酰化吲哚的反应得到具有反选择性的1,1,2-三芳基烷烃。这一结果是相对于巴赫的含α-烷基苄基阳离子的面部非对映选择性的逆转。布朗斯台德酸（TFA）或路易斯酸（BF3.OEt2）促进反应，提供不同的非对映选择性和反应性。两种反应伙伴的电子性质都强烈影响反应速率和产物非对映选择性，并且似乎在动力学控制下起作用。这种化学性质提供了空间拥挤的四取代乙烷的有效途径。
