novel agonists acting at metabotropic glutamate (mGlu) 2/3 receptors, we have explored the effect of structural modifications of 1S,2S,5R,6S-2-aminobicyclo[3.1.0]hexane-2,6-dicarboxylate (LY354740), a potent and pharmacologically balanced mGlu2/3 receptor agonist. Incorporation of relatively small substituents (e.g., F, O) at the C4 position of this molecule resulted in additional highly potent mGlu2/3
作为我们对鉴定作用于代谢型谷氨酸(mGlu)2/3受体的新型激动剂的兴趣的一部分,我们探索了1 S,2 S,5 R,6 S的结构修饰作用-2-氨基双环[3.1.0] -2,6-己二酸己烷酯(LY354740),一种有效且药理平衡的mGlu2 / 3受体激动剂。在此分子的C4位上引入相对较小的取代基(例如F,O)会导致额外的高效mGlu2 / 3激动剂,与其他mGlu受体亚型相比,具有出色的选择性,同时还添加了较大的C4取代基(例如SPh )导致激动剂效能的丧失和/或出现弱的mGlu2 / 3受体拮抗剂活性。体内α-氟取代类似物(LY459477)的进一步表征表明,该分子在大鼠中具有良好的口服生物利用度,并且在不损害神经肌肉协调性的剂量下有效抑制了苯环利定诱发的自发活动。
