We have examined the pyrazolo[1,5-a]pyrimidine scaffold as a novel core structure for estrogen receptor ligands. Attachment of various substituents has helped to define the orientation of this heterocycle in the ligand-binding pocket as one in which a pendant phenol rather than the hydroxylpyrimidine serves as a mimic of the A-ring of estradiol.
我们已经检查了吡唑并[1,5-a]嘧啶支架作为雌激素受体配体的新型核心结构。各种取代基的连接已帮助在配体结合袋中定义了该杂环的取向,其中侧苯酚而不是羟基嘧啶可作为雌二醇A环的模拟物。
