  Synthesis and Pharmacological Identification of Neutral Histamine H₁-Receptor Antagonists

  摘要：

  In the present study we searched for neutral antagonists for the human histamine H-1-receptor (H,R) by screening newly synthesized ligands that are structurally related to H1R agonists for their affinity using radioligand displacement studies and by assessing their functional activity via performing a NF-kappaB driven reporter-gene assay that allows for the detection of both agonistic and inverse agonistic responses. Starting from the endogenous agonist for the H1R, histamine, we synthesized and tested various analogues and ultimately identified several compounds with partial inverse agonistic properties and two neutral Hi-receptor antagonists, namely 2-[2-(4,4diphenylbutyl)-1H-imidazol-4-yl]ethylamine (histabudifen, 18d) (pK(i) = 5.8, alpha = 0.02) and 2-[2-(5,5-diphenylpentyl)-1H-imidazol-4-yl]ethylamine (histapendifen, 18e) (pK(i) = 5.9, alpha = -0.09).

  The influence of alkyl chain length variation on the histamine H-3 receptor activity of histamine homologs 1 was investigated. A series of 4(5)-(omega-aminoalkyl)-1H-imidazoles 1 was prepared with an alkyl chain length varying from one methylene group to 10 methylene groups. Besides the H-3 activity, the affinities of these compounds for the H-1 and H-2 receptors were determined. The ethylene chain of histamine is optimal for agonistic activity on all three histamine receptor subtypes. For the H-3 receptor, elongation of the alkyl chain from three methylene groups on leads to compounds with antagonistic properties. 4(5)-(5-Aminopentyl)-1H-imidazole (impentamine, 1e) is the most potent and selective H-3 antagonist from this series of 4(5)-(omega-aminoalkyl)-1H-imidazoles 1, with a pA(2) value of 8.4 (on guinea pig jejunum). A specific antagonistic binding site for this compound is proposed.
