In this work we describe the optimization of a lead compound based on the quinazoline template to give a new series of potent pyrido[3,2-d]pyrimidines as histamine H4 receptor antagonists. The pyrido[3,2-d]pyrimidine ligands have significantly reduced hERG binding compared to clinical stage compound PF-3893787 while showing good affinities at the human and rodent histamine receptors. The receptor residence
在这项工作中,我们描述了基于喹唑啉模板的前导化合物的优化,以给出一系列新的有效的吡啶并[3,2- d ]嘧啶类作为组胺H 4受体拮抗剂。与临床阶段化合物PF-3893787相比,吡啶并[3,2- d ]嘧啶配体具有显着降低的hERG结合,同时对人和啮齿类组胺受体表现出良好的亲和力。确定了这些新化合物中几种对人H 4 R的受体停留时间,并将其与JNJ7777120和PF-3893787进行了比较。吡啶并[3,2- d ]嘧啶的停留时间低于JNJ7777120,但与PF-3893787的停留时间相当。总体而言,吡啶基[3,2- d]嘧啶类药物显示出优异的体外特性,因此有必要在人类疾病的相关模型中进行进一步研究。
