  Ring-substituted histaprodifen analogues as partial agonists for histamine H1 receptors: synthesis and structure–activity relationships

  摘要：

  Thirteen racemic benzene ring-substituted analogues of histaprodifen (8a; 2-[2-(3,3-diphenylpropyl)-1H-imidazol-4-yl]ethanamine), a novel lead for potent and selective histamine H-1-receptor agonists, have been prepared from substituted 4,4-diphenylbutyronitriles 5 via cyclization of the corresponding methyl butyrimidates 6 with 2-oxo-4-phthalimido-1-butyl acetate in liquid ammonia, followed by deprotection. Nitriles 5 were accessible by alkylation of either substituted diphenylmethanes with 3-bromopropionitrile or diethyl malonate with substituted 1-chloro-diphenylmethanes and subsequent standard reactions. The title compounds 8 displayed partial agonism on contractile H-1 receptors of the guinea-pig ileum (E-max = 2-98% relative to histamine) and, compared with the endogenous agonist, were endowed with agonist potencies of 4-92%. The meta fluorinated (gc) and meta chlorinated (8f) analogues showed the highest relative potency in this series (95% confidence Limits 85-99% and 78-102%), but did not exceed the value of the lead 8a (99-124%). Compound 8c (2-[2-[3-(3-fluorophenyl)-3-phenylpropyl]-1H-imidazol-4-yl]ethanamine) was a partial agonist at contractile H-1 receptors of the guinea-pig aorta (relative potency 154% vs. 100% for histamine) and at relaxation-mediating endothelial H-1 receptors of the rat aorta (relative potency 556% vs. 100% for histamine) and matched with the functional behaviour of 8a. Agonism observed for each compound was sensitive to blockade by the selective H-1-receptor antagonist mepyramine (pA(2) approximate to 9 (guinea-pig) and pA(2) approximate to 8 (rat aorta)). All histaprodifen analogues 8 stimulated neither histaminergic H-2/H-3, nor cholinergic M-3 receptors. They displayed only low to moderate affinity for these sites (H-2: pD'(2), < 5; H-3/M-3: pA(2) < 6). With regard to the substitution pattern on the benzene ring, there was no correlation between the histaprodifen series and the corresponding derivatives of another selective H-1-receptor agonist, viz. 2-phenylhistamine.

  demonstrated by HPLC-MS, the acylguanidines (bioisosteres of the alkylguanidines) were absorbed from the gut of mice and detected in brain. In GTPase assays using recombinant receptors, acylguanidines were more potent at the guinea pig than at the human H2R. At the hH1R and hH3R, the compounds were weak to moderate antagonists or partial agonists. Moreover, potent partial hH4R agonists were identified. Receptor

  N1-芳基（杂芳基）烷基-N2- [3-（1H-咪唑-4-基）丙基]胍是有效的组胺H2受体（H2R）激动剂，但由于缺乏口服生物利用度和CNS渗透性而削弱了它们的适用性。为了改善药代动力学，我们在胍基部分附近引入了羰基而不是亚甲基，从而将新型H2R激动剂的碱性降低了4-5个数量级。一些具有一个苯环的酰基胍比其二芳基类似物甚至更有效。如通过HPLC-MS证明的，酰基胍（烷基胍的生物等排体）从小鼠的肠中吸收并在脑中检测到。在使用重组受体的GTPase检测中，豚鼠的酰基胍比人的H2R更有力。在hH1R和hH3R处，这些化合物对中度拮抗剂或部分激动剂均弱。而且，确定了有效的部分hH4R激动剂。受体亚型的选择性取决于咪唑基丙基胍基团（特权结构），为包括强效H4R激动剂在内的独特药理学手段开辟了道路。
