Cardiac glycosides. 1. A systematic study of digitoxigenin D-glycosides
Fullerton,Kihara,Deffo,Kitatsuji,Ahmed,Simat,From,Rohrer
, p. 256 - 261 (2007/10/02)
A series of digitoxigenin glycosides was studied: five with β-D-sugars varying stepwise in sugar structure from β-D-digitoxose to β-D-galactose, including one β-D/α-D-pair. I50 values for these glycosides and digitoxigenin were determined with
