Metabolite Identification
Common Namedihydrodigoxigenin
DescriptionDihydrodigoxigenin is a cardiac glycoside, a chemical class known for its role in modulating cardiac function. Its chemical structure features a steroid nucleus with a sugar moiety, which is characteristic of glycosides. Dihydrodigoxigenin is involved in metabolic pathways related to the pharmacokinetics of digoxin, a well-known cardiac drug. It is identified as a metabolite alongside other important compounds such as digoxigenin monodigitoxoside and apigenin (PMID:39239200 ). Analytical methods, including high-performance liquid chromatography, have been developed for the determination of dihydrodigoxigenin in biological samples, particularly urine (PMID:3782404 ). Furthermore, studies utilizing chromatographic data and NMR spectroscopy have facilitated the identification of its epimers, specifically the 20R and 20S configurations, which are essential for understanding its biological activity (PMID:2858377 ). The C20 configuration and solution conformation of these epimers have also been characterized using circular dichroism and NMR spectroscopy, providing insights into their structural properties (PMID:6302244 ). Overall, dihydrodigoxigenin plays a significant role in the metabolic pathways of cardiac glycosides, contributing to their therapeutic effects.
