imidazolylcyclopropane scaffold and identified potent non-selective antagonists for histamine H3 and H4 receptor subtypes. In this study, to develop H4 selective ligands, we newly designed and synthesized cyclopropane-based derivatives having an indole, benzimidazole, or piperazine structure, which are components of representative H4 selective antagonists such as JNJ7777120 and JNJ10191584. Among the
我们先前设计和合成了一系列具有咪唑基环丙烷支架的组胺类似物,并确定了组胺H 3和H 4受体亚型的有效非选择性拮抗剂。在这项研究中,为了开发H 4选择性配体,我们新设计并合成了具有吲哚,苯并咪唑或哌嗪结构的环丙烷基衍生物,它们是代表性的H 4选择性拮抗剂(如JNJ7777120和JNJ10191584)的组成部分。在合成的衍生物中,与苯并咪唑共轭的咪唑基环丙烷12和13显示出对H 3和H 4的结合亲和力。与众所周知的非选择性H 3 / H 4拮抗剂硫代过酰胺的受体相当。这些结果表明,H 4受体中基于环丙烷的H 3 / H 4配体的结合方式可以与吲哚/苯并咪唑-哌嗪衍生物的结合方式不同。
