Background:

Cyproheptadine-d3 is intended for use as an internal standard for the quantification of cyproheptadine by GC- or LC-MS. Cyproheptadine is an antihistamine with antiserotonergic and anticholinergic activities.1 It binds to histamine H1, muscarinic, and serotonin 5-HT2 receptors (Kis = 0.38, 1.26, and 0.83 nM, respectively, in radioligand binding assays).2 Cyproheptadine reduces histamine-induced spasms in isolated guinea pig ileum (IC75 = 0.0014 μg/ml).3 It protects against intravenous histamine diphosphate-induced death with a 50% protective dose (PD50) value of 0.08 mg/kg and delays induction of aerosolized histamine diphosphate-induced coughing (ED100sec = 0.29 mg/kg) in guinea pigs. Cyproheptadine also inhibits the lysine methyltransferase SET7/9 (IC50 = 1 μM), decreasing the expression of estrogen receptor α (ERα) in MCF-7 cells.4 Formulations containing cyproheptadine have been used in the treatment of allergic reactions including rhinitis, conjunctivitis, and urticaria.
