asymmetric synthesis and biological activity of (2S,1'S,2'S,3'R)-2-(2'-carboxy-3'-methylcyclopropyl) glycine 7 and its epimer at the C3' center 6 are described. Compound 7 is a highly potent and selective agonist for group 2 metabotropric glutamate receptors (mGluRs). It is also systemically 4 orders of magnitude more active in the fear-potentiated startle model of anxiety in rats than the rigid constrained
描述了(2S,1'S,2'S,3'R)-2-(2'-羧基-3'-甲基环丙基)甘氨酸7及其在C3'中心6的差向异构体的不对称合成和生物活性。化合物7是第2组代谢型谷氨酸受体(mGluRs)的高效选择性激动剂。与刚性约束双环系统LY354740相比,它在大鼠恐惧增强惊恐模型中的全身活性还高4个数量级。因此,我们已经表明,构象受限的双环系统的高分子复杂性不是获得高度选择性和有效的第2组mGluRs激动剂的必要条件。
