Notes: Antazoline is a histamine H1 receptor antagonist that binds to histamine H1receptors with a Ki value of 38.4 nM in cell membranes expressing human recombinant H1 receptors.{33247} Antazoline reduces histamine-induced IL-6 and IL-8 production in human conjunctival epithelial cells (IC50s = 1 and 0.652 μM, respectively). It completely prevents anaphylaxis in rabbits sensitized to egg albumin and increases survival in a guinea pig model of histamine-induced bronchospasm.{40285} Antazoline (10-30 µM) eliminates atrial fibrillation induced by acetylcholine and isoproterenol (Item No. 15592) in isolated rabbit hearts by increasing the atrial effective refractory period and interatrial conduction time in a dose-dependent manner.{40286} Antazoline also binds to NMDA receptors (Ki = 13 μM) and reduces glutamate-induced toxicity in cerebellar granule cells (EC50 = 13 μM).{40287}
