MedKoo CAT#: 574291


Description: YHL 00997, also known as N-desmethyl Rosuvastatin sodium salt hydrate is an active metabolite of the HMG-CoA reductase inhibitor Rosuvastatin. N-desmethyl Rosuvastatin is formed when Rosuvastatin undergoes demethylation, primarily by the cytochrome P450 (CYP) isoform CYP2C9 and to a lesser extent by CYP2C19 and CYP3A4. This product has no formal name at the moment. For the convenience of communication, a temporary code name was therefore proposed according to MedKoo Chemical Nomenclature (see web page: https://www.medkoo.com/page/naming).
