novel A 2A receptor antagonists with excellent water solubility. As described in the accompanying paper, the antagonists were first optimized to remove an unsubstituted furyl moiety, with the aim of avoiding the potential metabolic liabilities that can arise from the presence of an unsubstituted furan. This effort identified a series of potent and selective methylfuryl derivatives. Herein, we describe
以前,我们已经描述了一系列具有出色水溶性的新型A 2A受体拮抗剂。如随附文件中所述,首先对拮抗剂进行优化以去除未取代的呋喃基部分,目的是避免由于未取代的呋喃的存在而可能引起的潜在代谢负债。这项工作确定了一系列有效的和选择性的甲基呋喃基衍生物。在本文中,我们描述了该系列的进一步优化,以提高效力,维持人A 2A对人A 1受体的选择性以及最小化针对hERG通道的活性。另外,报道了观察到的针对人和大鼠A 2A受体的构效关系。
