    Product Description

    Iodophenpropit is a histamine H3 receptor antagonist (pA2 = 9.6 in guinea pig intestine, which has a high endogenous expression of H3 receptors).1 It increases forskolin-induced cAMP production in SK-N-MC cells expressing the recombinant human H3 receptor (EC50 = 25.1 nM).2 It is also an inhibitor of NR1/NR2A, NR1/NR2B, NR1/NR2C, and NR1/NR2D subunit-containing NMDA receptors (IC50s = 1.3, 1.4, 9.7, and 14 µM, respectively, for the rat recombinant receptors).3 Iodophenpropit induces scratching behavior in mice when administered intradermally at a dose of 10 nmol and reduces amygdala-kindled seizure duration in rats (ED50 = 2.54 mg/kg).4,5
