olyl)propyl]isothiourea) binds to both the human histamine H3 receptor (H3R) and H4 receptor (H4R). In this paper, we describe the synthesis and pharmacological characterization of a series of clobenpropit analogs, which vary in the functional group adjacent to the isothiourea moiety in order to study structural requirements for H3R and H4R ligands. The compounds show moderate to high affinity for
先前的研究表明,clobenpropit(N-(4-氯苄基)-S- [3-(4(5)-咪唑基丙基)丙基]异硫脲)与人组胺H 3受体(H 3 R)和H 4受体均结合(H 4 R)。在本文中,我们描述了一系列clobenpropit类似物的合成和药理学表征,它们在与异硫脲部分相邻的官能团中有所不同,以研究H 3 R和H 4 R配体的结构要求。这些化合物对人的H 3 R和H 4均显示中等至高亲和力此外,与异硫脲部分连接的官能团的变化调节了配体在H 4 R的内在活性,范围从中性拮抗作用到完全激动作用。为了解释H 3 R和H 4 R的亲和力,已生成QSAR模型。
