Abstract:
Two series of triamino pyrimidines and a series of triamino pyridines have been synthesized and their structure-activity relationships evaluated for activity at the H4 receptor in competitive binding and functional assays. Small structural changes in these three hetereoaromatic cores influenced the functional activity of these compounds.
