  2,4-Diaminopyrimidines as histamine H4 receptor ligands—Scaffold optimization and pharmacological characterization

  摘要：

  The human histamine H-4 receptor (hH(4)R) is a promising new target in the therapy of inflammatory diseases and disorders of the immune system. For the development of new H4R antagonists a broad ligand-based virtual screening was performed resulting in two hits. The dissection of their common annelated aromatic core into its heteromonocyclic components showed that 2,4-diaminopyrimidine is a potent hH(4)R affinity scaffold, which was comprehensively investigated. Structure-activity relationship studies revealed that slight structural changes evoke extensive differences in functional activities and potencies: while o-and p-substituted benzyl amines mainly showed partial agonism, m-substituted and rigidified ones exhibited inverse agonist efficacy.
