The structure-activity relationship (SAR) exploration using 2-(2-furanyl)-7-phenyl[1,2,4]triazolo-[1,5-c]pyrimidin-5-amine (1) as a template led to the identification of a novel class of potent and selective adenosine A2A receptor (AR) antagonists. However, these compounds were found to be associated with significant hERG activity. This report discusses the strategy and outcome of an expanded SAR focused
以2-(2-呋喃基)-7-苯基[1,2,4]三唑-[1,5-c]嘧啶-5-胺(1)为模板的结构-活性关系(SAR)探索导致一类新型的有效和选择性腺苷A2A受体(AR)拮抗剂的鉴定。然而,发现这些化合物与显着的hERG活性有关。本报告讨论了针对解决hERG责任而扩大的SAR的策略和结果。结果,化合物21和24具有优异的体外概况,高度有希望的体内概况以及可接受的hERG通道抑制水平。
