high degree of selectivity over A1, A2B, and A3 receptors. Compounds from this new scaffold resulted in the discovery of highly potent, selective, stable, and moderate brain penetrating compound 33. Compound 33 endowed with satisfactory in vitro and in vivo pharmacokinetics properties. Compound 33 demonstrated robust oral efficacies in two commonly used models of Parkinson’s disease (haloperidol-induced
腺苷A 2A受体(A 2A AdoR)拮抗作用是一种正在开发中的非多巴胺能治疗帕金森氏病的方法。此前我们已经报道了7-甲氧基-4-吗啉代-苯并噻唑衍生物作为A 2A AdoR拮抗剂的治疗潜力。我们在此描述了一系列新颖的[1,2,4] triazolo [5,1- f ]嘌呤-2-酮衍生物,该衍生物表现出对A 2A受体的功能拮抗作用,对A 1,A 2B,和A 3受体。这种新型支架的化合物导致发现了高效,选择性,稳定和中等脑穿透性化合物33。化合物33具有令人满意的体外和体内药代动力学特性。化合物33在帕金森氏病的两种常用模型(氟哌啶醇诱导的僵直性脑病和6-OHDA损伤的大鼠模型)和抑郁症(TST和FST小鼠模型)中显示出强大的口服功效。
