(NMDAR) hypofunction. It has been demonstrated that activation of metabotropic glutamate receptor 5 (mGluR5) enhances NMDA receptor function, suggesting the potential utility of mGluR5 positive allosteric modulators (PAMs) in the treatment of schizophrenia. Herein we describe the optimization of an mGluR5 PAM by replacement of a phenyl with aliphatic heterocycles and carbocycles as a strategy to reduce
精神分裂症是一种严重疾病,影响数百万患者,并与N-甲基-d-天冬氨酸受体(NMDAR)功能低下有关。已经证明,代谢型谷氨酸受体5(mGluR5)的激活增强了NMDA受体的功能,表明mGluR5阳性变构调节剂(PAMs)在精神分裂症的治疗中具有潜在的实用性。本文中,我们描述了通过用脂肪族杂环和碳环取代苯基来优化mGluR5 PAM的方法,以此作为降低联芳基乙炔化学型生物活化的策略。用二氟环丁烷替代,然后进行进一步优化,最终鉴定出化合物32,即一种具有低倍生物活性的低倍移PAM。
