Popis: We designed and synthesized conformationally rigid histamine analogues with a bicyclo[3.1.0]hexane scaffold. All the compounds were selectively bound to the H3 receptor subtype over the H4 receptor subtype. Notably, compound 7 showed potent binding affinity and over 100-fold selectivity for the H3 receptors (Ki = 5.6 nM for H3 and 602 nM for H4). These results suggest that the conformationally rigid bicyclo[3.1.0]hexane structure can be a useful scaffold for developing potent ligands selective for the target biomolecules.
