  Characterization of the Histamine H₄ Receptor Binding Site. Part 1. Synthesis and Pharmacological Evaluation of Dibenzodiazepine Derivatives

  摘要：

  A series of dibenzodiazepine derivatives was synthesized to probe the binding site of the recently discovered histamine H-4 receptor (H4R). Optimization of the lead structure clozapine (2) resulted in (E)-7-chloro-11-(4-methylpiperazin-l-yl) dibenzo[b, f][1,4] oxazepine (7j), a potent H4R agonist (H4R, pK(i) = 7.6). Pharmacological data suggests that the series of nonimidazole compounds can be used to describe the orthosteric binding site of the H4R because both 2 and 7j displace [H-3] histamine in a competitive manner. Furthermore, it is demonstrated that the effects of 7j are competitively antagonized by the selective H4R antagonist JNJ 7777120 (1), indicating considerable overlap of their binding sites. On the basis of the derived structure-activity relationships and additional pharmacological results, a pharmacophore model was constructed, which will be the premise for the design of novel H4R ligands.

  Abstract A facile one-pot protocol for the synthesis of substituted dibenzoxazepinones and pyridobenzoxazepinones from commercially available aryl/heteroaryl halides and amino phenols using octacarbonyldicobalt (Co2(CO)8) as an effective metal carbonyl source has been demonstrated. This method proceeds via the sequential coupling of aryl/heteroaryl halides with aminophenol by amidation and intramolecular
