制备方法与用途

用途

7-溴-2-氯喹唑啉是一种杂环衍生物，主要用于医药中间体。

制备

首先，在油浴中将2-氨基-4-溴苯甲醛（13克，65毫摩尔）和尿素（54.6克，910毫摩尔）加热至180℃并保持2小时。随后，冷却反应物至室温，并加入500毫升水。将混合物在室温下搅拌1小时后，过滤得到白色固体中间体7-溴喹唑啉-2(1H)-酮（16克，产率93%）。

接着，在氮气保护下，于油浴中加热中间体7-溴喹唑啉-2(1H)-酮（16克，71毫摩尔）和POCl3（280克，1.84摩尔），温度保持在110℃，持续3小时。冷却至室温后，倒入4000克冰/水中，并搅拌1小时。接着用乙酸乙酯（2000毫升 × 2）萃取有机层，用盐水洗涤并经无水Na2SO4干燥。将溶剂在真空下蒸发得到粗产物，通过层析法（乙酸乙酯/石油醚0/1至1/5比例）纯化后，最终获得白色固体7-溴-2-氯喹唑啉（10克，产率53%）。

  氨基喹唑啉作为脑渗透剂和选择性 LRRK2 抑制剂的结构导向发现

  摘要：

  富含亮氨酸的重复激酶 2 (LRRK2) 蛋白在遗传和功能上与帕金森病 (PD) 相关，这是一种致残和进行性神经退行性疾病，目前的治疗范围和疗效有限。在本报告中，我们描述了由结构支持支持的严格的从点击到领先的优化活动，最终发现了以化合物22和24为代表的脑渗透性候选质量分子. 这些化合物对激酶组表现出显着的选择性，并提供良好的口服生物利用度和低预计人体剂量。此外，他们展示了立体化学设计元素的实施，这些元素有助于提高极性和氢键供体 (HBD) 计数的效力和选择性，同时保持以低水平的转运蛋白介导的外排为代表的对中枢神经系统友好的特征并鼓励临床前模型中的大脑渗透。
