  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.

  The direct formation of aryl C−O bonds via the intramolecular dehydrogenative coupling of a C−H bond and a pendant alcohol represents a powerful synthetic transformation. Herein, we report a method for intramolecular arene C−H etherification via an umpoled alcohol cyclization mediated by an I(III) N-HVI reagent. This approach provides access to functionalized chromane scaffolds from primary, secondary
