core scaffold led to the stereoselective synthesis of four new conformationally restricted Glu analogues, 2a–d. Most interestingly, 2a retained a selective agonist activity profile at mGlu2 (EC50 in the micromolar range), whereas 2c/2d were both selective agonists at group III, subtypes mGlu4,6,8. In general, 2d was 20-fold more potent than 2c and potently activated mGlu4,6,8 in the low–mid nanomolar
代谢型谷氨酸(Glu)受体(mGluRs)在调节大脑兴奋性神经传递中起关键作用。总共确定了八种亚型,并将其分为三组,第一组(mGlu1,5),第二组(mGlu2,3)和第三组(mGlu4,6-8)。在本文中,我们介绍了一个L-2,4-syn-取代的Glu类似物1d,它在mGlu2上显示了对其余mGluR亚型的选择性激动剂活性。对核心支架的建模研究和重新设计导致了四个新的构象受限的Glu类似物2a - d的立体选择性合成。最有趣的是,2a在mGlu2(EC 50在微摩尔范围内)保留了选择性激动剂活性谱,而2c /2d均为第III组mGlu4、6、8亚型的选择性激动剂。通常,在低-中纳摩尔范围内,2d的效力比2c强20倍,并且有效活化了mGlu4、6、8。
