A series of novel, potent CCR1 inhibitors was developed from a moderately active hit using an iterative parallel synthesis approach. The initial hit (composed of three subunits: an amine, a central amino acid, and an N-terminal cap) became the basis for a series of parallel chemical libraries designed to generate SAR data. Libraries were synthesized that explored each of the three subunits; the CCR1
使用迭代平行合成方法,从中等活性的化合物中开发出了一系列新型有效的CCR1抑制剂。最初的命中物(由三个亚基组成:胺,中心氨基酸和N端帽)成为一系列旨在生成SAR数据的平行化学文库的基础。合成了探索三个亚基中每个亚基的文库。获得的CCR1结合数据显示以下:(1)对胺的变化没有很好的耐受性;(2)在分子中心优选小的烷基氨基酸;(3)在N端的取代通常被很好地容忍。这些数据被用来推动系列的优化,最终为引线提供了28 nM的CCR1结合IC 50(48)。该铅对小鼠显示出对CCR1的选择性高于其他CCR家族成员,具有很高的微粒体稳定性和良好的药代动力学。
