4-Methylhistamine is a histamine H4 receptor agonist (Ki = 50 nM).{36324} It is >100-fold selective for H4 over other histamine receptors. 4-Methylhistamine inhibits CRE-β-galactosidase activity induced by forskolin (Item No. 11018) with an EC50 value of 39.8 nM in SK-N-MC cells transfected with the human H4 receptor. It induces a change in eosinophil shape (EC50 = 0.36 μM) and stimulates migration of murine bone marrow mast cells (EC50 = 12 μM), activities that can be inhibited by the histamine H4 antagonist JNJ-7777120 (Item No. 10011925). Intratracheal administration of 4-methylhistamine (10 μg/animal) reduces airway resistance and inflammation and increases the number of CD4+CD25+FoxP3+ regulatory T cells in a mouse model of allergic asthma.{36323} 4-Methylhistamine also reduces epidermal hyperplasis, hyperkeratosis, and lymphocyte infiltration and increases the number of CD4+CD25+FoxP3+ regulatory T cells in a mouse model of psoriasis induced by imiquimod (Item No. 14956).{36325}

    CAY10512 – 500 mg

    The nuclear factor-κB (NF-κB) regulates the expression of numerous genes involved in immunity and inflammation, cellular stress responses, growth, and apoptosis. Resveratrol, a polyphenolic trans-stilbene, is a known inhibitor of the activation of NF-κB and exhibits activity against a wide variety of cancer cells. CAY10512 is a substituted trans-stilbene analog of resveratrol that is 100-fold more potent as measured by antioxidant activity. The IC50 value for inhibition of TNFα-induced activation of NF-κB by CAY10512 is 0.15 µM compared to 20 µM by resveratrol.{14545}
