Thioperamide·maleate is a selective histamine H3 receptor antagonist and H4 receptor inverse agonist that has been shown to cross the blood-brain barrier. This compound binds to rat cerebral cortical cells in vitro, has a pKi value of 8.4. Additionally, thioperamide maleate blocks eosinophil shape change (IC50 = 1.4 μM) and chemotaxis (IC50) = 519 nM) induced by histamine.
