appropriate cyclic D- or L-amino acids by the Amdt-Eistert homologation followed by reduction of the resulting esters. Incorporation of these pharmacophores was achieved via a novel Mitsunobu alkylation of 4-hydroxyquinolones. The key amine pharmacophore for binding to the rat GnRH receptor was most active in the S-configuration. Ring size was not important for potency with 4, 5, 6, and 7-membered ring amines
报道了喹诺酮GnRH拮抗剂(+/-)-1对映体的合成和体外活性。由适当的环状D-或L-氨基酸,通过Amdt-Eistert同系反应,然后还原所得酯,制备手性氨基醇。这些药效基团的掺入是通过4-羟基喹诺酮类的新Mitsunobu烷基化实现的。与大鼠GnRH受体结合的关键胺药效团在S构型中最活跃。环的大小对于效能而言并不重要,其中4、5、6和7元环胺表现出相似的效能。
