are estrogen receptor (ER) antagonists of modest potency that we have described previously. Guided by the crystal structure of an ER-ligand complex that we have obtained with one of these compounds, we prepared analogs that contain a basic side chain at the 2- or 3-aryl group and quickly found one that, according to the structure-based prediction, shows an increase in binding affinity and antagonist
2,3-二芳基吡唑并[1,5-a]嘧啶是我们之前所述的中等效力的雌激素受体(ER)拮抗剂。在我们用其中一种化合物获得的ER-配体络合物的晶体结构的指导下,我们制备了在2-或3-芳基上包含基本侧链的类似物,并根据结构迅速找到了一个类似物,基于预测的结果显示,结合亲和力和拮抗剂效能增加,并且残留激动剂活性降低。
