Here we report a new series of adenosine receptor A2A antagonists based on a 4-amino-5-carbonitrile pyrimidine template. Compounds from this new template exhibit excellent potency and ligand efficiency with low cytochrome P450 inhibition. Although the clearance remains moderate to high, the leading compound, when dosed orally as low as 3 mg/kg, demonstrated excellent efficacy in the haloperidol induced
在过去的十年中,腺苷A 2A拮抗剂已成为帕金森氏病的潜在治疗方法。我们最近报道了一系列使用杂环作为潜在不稳定乙酰胺的生物等位基因的腺苷受体拮抗剂。这些化合物虽然显示出出色的效能和配体效率,但受到中等程度的细胞色素P450抑制作用和高清除率的困扰。在这里我们报告了一系列新的腺苷受体A 2A基于4-氨基-5-腈嘧啶模板的拮抗剂。来自这个新模板的化合物具有出色的效价和配体效率,并具有低的细胞色素P450抑制作用。尽管清除率仍然保持中到高水平,但当口服低至3 mg / kg时,前导化合物在氟哌啶醇诱导的帕金森氏病僵直大鼠模型中显示出优异的疗效。
