Homologation of (S)-glutamic acid (Glu, 1) and Glu analogues has previously provided ligands with activity at metabotropic Glu receptors (mGluRs). The homologue of ibotenic acid (7), 2-amino-3-(3-hydroxy-5-isoxazolyl)propionic acid (HIBO, 8), and the 4-phenyl derivative of 8, compound 9a, are both antagonists at group I mGluRs. Here we report the synthesis and molecular pharmacology of HIBO analogues
(S)-谷氨酸(Glu,1)和Glu类似物的同源性先前已经提供了对代谢型Glu受体(mGluRs)具有活性的配体。ibotenic acid(7),2-氨基-3-(3-hydroxy-5-isoxazolyl)丙酸(HIBO,8)和化合物8a的4-苯基衍生物的同系物都是I组的拮抗剂mGluR。在这里,我们报告含有不同的4-芳基取代基的HIBO类似物9b-h的合成和分子药理作用。所有这些化合物在I组mGluRs上均具有拮抗剂活性,但在II组和III组mGluRs上无活性。
