To develop novel estrogen receptor (ER) ligands, ring-fused derivatives of the hormonally active (1R,2S)/(1S,2R)-1-(2-chloro-4-hydroxyphenyl)-2-(2,6-dichloro-4-hydroxyphenyl)ethylenediamine 4b were synthesized. (2R,3S)/(2S,3R)-2-(2-Chloro-4-hydroxyphenyl)-3-(2,6-dichloro-4-hydroxyphenyl)piperazine 4 induced ligand-dependent gene expression in MCF-7-2a cells, stably transfected with the plasmid ERE(wtc)luc
若要开发新型的雌激素受体(ER)配体,激素活性(1R,2S)/(1S,2R)-1-(2-氯-4-羟基苯基)-2-(2,6-二氯)的环稠合衍生物合成了-4-羟基苯基)乙二胺4b。(2R,3S)/(2S,3R)-2-(2-氯-4-羟基苯基)-3-(2,6-二氯-4-羟基苯基)哌嗪4诱导的配体依赖性基因在MCF-7-中的表达用质粒ERE(wtc)luc稳定转染的2a细胞,因此用作前导结构。芳族环(4-OH(1),2-F,4-OH(2),2-Cl,4-OH(3),2,6-Cl2,3-OH(研究了5),2,6-Cl2,4-OH(6)以及N-乙基链对ER结合和基因表达激活的影响。合成从各自的甲氧基取代的(1R,2S)/(1S,2R)-构型的1,2-二芳基乙二胺6b至4b开始,将其与草酸二甲酯反应以获得5,6-二芳基哌嗪-2,3-二酮。用BH 3 *四氢呋喃还原并用BBr 3裂解醚得到哌嗪1-6。用于获
