Abstract
Background
The human histamine H4 receptor (hH4R) is a promising new target in the therapy of inflammatory or immune system diseases.
Methods
For the development of new hH4R ligands, a broad virtual screening was performed and two hits were identified. Their annelated heterocyclic core was optimized with regard to affinity and potency.
Results
Pharmacological characterization of the resulting diaminopyrimidines revealed different agonist and antagonist properties within the same scaffold.
