therapeutic intervention in the alleviation of the symptoms associated with Parkinson’s disease. This is thought to occur, at least in part, by increasing the sensitivity of the dopaminergic neurons to the residual, depleted levels of striatal dopamine. We herein describe a novel series of functionalized triazolo[4,5-d]pyrimidine derivatives that display functional antagonism of the A2A receptor. Optimization
人类A 2A受体的拮抗作用被认为是减轻与帕金森氏病有关的症状的治疗干预点。认为这至少部分地通过增加多巴胺能神经元对残留的,耗尽的纹状体多巴胺水平的敏感性而发生。我们在此描述了一系列新颖的功能化的三唑并[4,5- d ]嘧啶衍生物,其显示出对A 2A受体的功能拮抗作用。这些化合物的优化已导致关键衍生物的效能,选择性和药代动力学特性得到改善。这些努力导致发现了60(V2006 / BIIB014),其在帕金森氏病的常用模型中证明了强烈的口服活性。此外,该衍生物已显示出优异的临床前药代动力学,并已成功完成I期临床研究。目前,该化合物正在与Biogen Idec合作进行进一步的临床评估。
