| | DIGITOXIGENIN Usage And Synthesis |
| Uses | Cardiotonic;Na+ K+ ATPase inhibitor | | Definition | ChEBI: Digitoxigenin is a 5beta-cardenolide that is 5beta-cardanolide with hydroxy substituents at the 3beta- and 14beta-positions and double bond unsaturation at C(20)-C(22). It is a 3beta-hydroxy steroid and a 14beta-hydroxy steroid. It derives from a hydride of a 5beta-cardanolide. | | Purification Methods | Dissolve digitoxigenin in EtOAc, wash it with H2O, dry it (Na2SO4), evaporate and recrystallise it from 40% aqueous EtOH or aqueous MeOH then EtOAc/Et2O. The UV has max at 218nm ( 14,500 M-1cm-1). The 3-acetate crystallises from Me2CO/Et2O with m 222-227o, [] D 20 +21o (c 1, CHCl3). [Wyss et al. Helv Chim Acta 43 644 1960, Cruz et al.
