    Product Description

    Desethylchloroquine-d4 is intended for use as an internal standard for the quantification of desethylchloroquine (Item No. 30113) by GC- or LC-MS. Desethylchloroquine is a major active metabolite of chloroquine (Item No. 14194).1 Desethylchloroquine is formed when chloroquine undergoes dealkylation, primarily by the cytochrome P450 (CYP) isoforms CYP2C8 and CYP3A4 and to a lesser extent by CYP2D6. It inhibits the growth of the P. falciparum strain LA136 in vitro (IC50 = 9.9 ng/ml).2

    WARNING This product is not for human or veterinary use.
