identified as a potent (EC50 = 50.1 nM, 50.5% GluMax) and selective mGlu4 PAM with an excellent rat DMPK profile (in vivo rat CLp = 3.1 mL/min/kg, t1/2 = 445 min, CYP1A2 IC50 > 30 μM). Compound 27o was also active in reversing haloperidol induced catalepsy in a rodent preclinical model of Parkinson’s disease.
这项工作描述了新型6-(1 H-吡唑并[4,3 - b ]吡啶-3-基)氨基-苯并[ d ]异噻唑-3-羧酰胺的发现和表征,其为mGlu 4 PAM。与先前发现的mGlu 4 PAM相比,该支架提供了改善的代谢清除率和CYP1A2谱。从这项工作中,鉴定出27o(VU6001376)是有效的(EC 50 = 50.1 nM,50.5%GluMax)和选择性mGlu 4 PAM,具有出色的大鼠DMPK谱(体内大鼠CL p = 3.1 mL / min / kg,t 1/2 = 445分钟,CYP1A2 IC 50 > 30μM)。复合27o 在帕金森氏病的啮齿动物临床前模型中,氟哌啶醇还有效逆转氟哌啶醇引起的僵直。
