is more than 900-fold selective for mGlu5 versus the other mGlu receptors, and binding studies established a Ki value of 4.4 nM at a known allosteric binding site. Compound 27 had a clearance of 19.3 and 15.5 mL/min/kg in rats and cynomolgus monkeys, respectively. Imaging studies using a known mGlu5 PET ligand demonstrated 50% receptor occupancy at an oral dose of 0.8 mg/kg in rats and an intravenous
支持mGlu 5 NAM在治疗各种精神病和神经退行性疾病中的潜在效用的临床前证据是广泛的,并且许多此类分子已进入临床试验。尽管临床研究取得了令人鼓舞的结果,但尚无小分子mGlu 5 NAM进入市场。在这里,我们介绍N-(5-氟吡啶-2--2-基)-6-甲基-4-(嘧啶-5-基氧基)吡啶啉酰胺(27,VU0424238)的发现和评估,该化合物是用于临床评估的化合物。化合物27是用于组mGlu超过900倍的选择性5相对于其他mGlu受体,和结合研究建立了ķ我在已知的变构结合位点处的值为4.4nM。化合物27在大鼠和食蟹猴中的清除率分别为19.3和15.5 mL / min / kg。使用已知的mGlu 5 PET配体进行的影像学研究表明,大鼠口服剂量为0.8 mg / kg,狒狒静脉注射剂量为0.06 mg / kg时,受体占有率为50%。
