Four small, targeted libraries of differentially substituted amino pyrimidines were synthesized in moderate to good yields. Excellent regiochemistry was observed for substitution at C2/C4 with selectivity > 50:1 noted. All analogues were screened for their ability to interact with CRH1 and CRH2 receptors. In all instances only poor agonistic and/or antagonistic behaviour was noted at CRH2. However
以中等到良好的产率合成了四个小的,差异取代的氨基嘧啶的靶向库。在C2 / C4处观察到出色的区域化学取代作用,选择性> 50:1。筛选所有类似物与CRH1和CRH2受体相互作用的能力。在所有情况下,在CRH2处仅观察到不良的激动和/或拮抗行为。但是,有几种化合物是有效的和选择性的CRH1拮抗剂,最值得注意的是13a Ki = 39 nM。另外,我们利用了这些数据以及其他人最近报告的数据来完善我们原始的CRH1药效团(J Med。Chem。,1999,42,2351-2357)。
