Ouabain-d3

Ouabain-d3 is intended for use as an internal standard for the quantification of ouabain by GC- or LC-MS. Ouabain is a cardiac glycoside that has been found in S. gratus and has diverse biological activities. It inhibits the Na+/K+-ATPase isoforms alpha1beta1 and alpha2beta1 and human-ether-a-go-go (hERG), also known as Kv11.1 (IC50s = 97, 90, and 15.2 nM, respectively). Ouabain reduces the proliferation of PC3 prostate cancer and U937 lymphoma cells (EC50s = 210 and 94 nM, respectively). It inhibits the cytopathic effect of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in infected Vero cells (IC50 = in vivo. Formulations containing ouabain have been used in the treatment of atrial fibrillation, atrial flutter, and heart failure.Formal Name: 4-((1R,3S,5S,8R,9S,10R,11R,13R,14S,17R)-1,5,11,14-tetrahydroxy-10-(hydroxymethyl)-13-methyl-3-(((2R,3R,4R,5R,6S)-3,4,5-trihydroxy-6-methyltetrahydro-2H-pyran-2-yl)oxy)hexadecahydro-1H-cyclopenta[a]phenanthren-17-yl)furan-2(5H)-one-3,5,5-d3.
