As part of our ongoing research program aimed at the identification of highly potent, selective, and systemically active agonists for group II metabotropic glutamate (mGlu) receptors, we have prepared novel heterobicyclic amino acids (-)-2-oxa-4-aminobicyclo[3.1. 0]hexane-4,6-dicarboxylate (LY379268, (-)-9) and (-)-2-thia-4-aminobicyclo[3.1.0]hexane-4,6-dicarboxylate (LY389795, (-)-10). Compounds (-)-9
作为我们正在进行的研究计划的一部分,该计划旨在鉴定II型代谢型谷氨酸(mGlu)受体的高效,选择性和系统活性激动剂,我们制备了新型异双环氨基酸(-)-2-oxa-4-氨基双环[ 3.1。0] -4,6-二羧酸己烷(LY379268,(-)-9)和(-)-2-thia-4-氨基双环[3.1.0]己烷-4,6-二羧酸己烷(LY389795,(-)-10 )。化合物(-)-9和(-)-10在结构上与我们先前描述的纳摩尔浓度的II类mGlu受体激动剂,(+)-2-氨基双环[3.1.0]己烷-2,6-二羧酸一水合物(LY354740一水合物5),其中5的C 4-亚甲基单元被氧原子(如(-)-9)或硫原子(如(-)-10)取代。mGlu2 / 3受体拮抗剂([3H] LY341495)在大鼠大脑皮层匀浆中有效和立体定向置换了化合物(-)-9和(-)-10,显示的IC50值为15 +/- 4和8.4 +
