Brompheniramine maleate is a selective histamine H1 receptor antagonist with a Kd of 6.06 nM. Brompheniramine maleate has anticholinergic, antidepressant and analgesia properties and can be used for allergic rhinitis research[1][2]. IC₅₀ & Target H1 Receptor 6.06 nM (Kd) Page 1 of 2 www.MedChemExpress.com In Vitro In in vitro experiments, Brompheniramine blocks muscarinic cholinergic receptors in human chinese hamster ovary (CHO) cells, sodium and calcium channels in CHO cells, as well as potassium channels in human embryonic kidney 293 (HEK-293) [1] cells. Brompheniramine suppresses the transfected Nav1.5 channels from myocytes . MCE has not independently confirmed the accuracy of these methods. They are for reference only. In Vivo Brompheniramine as an antihistamine blocks sodium channels. Brompheniramine (3.0, 1.5, 1.1, 0.6, and 0.3 μmol) treatment shows cutaneous analgesic effect with an ED50 value of 0.89 in a rat model of infiltration anesthesia. Subcutaneous Brompheniramine induces dose-relatedly analgesic effects, and Brompheniramine induces prolonged analgesic duration[1]. MCE has not independently confirmed the accuracy of these methods.
