OBJECTIVE
The use of cardenolides in the treatment of cardiac insufficiency is well-established. However, the potential of cardenolides in tumor therapy has not been comprehensively studied. The aim of the present study was to characterize the cytotoxic effects of the new semisynthetic cardenolide
Bufalin was found to be a potent inducer of differentiation in human erythroleukemia K562 cells by examination of various differentiation markers (as assessed by the morphology, histochemistry, and the abilities to phagocytose latex particles, to reduce nitro-blue tetrazolium and to develop Fc
Bufalin, a bufadienolide type cardiotonic steroid that is one of the major components of the toad venom-prepared traditional Chinese medicine called Ch'an Su or Senso, exhibits a cardiotonic action by inhibiting the membranous Na(+),K(+)-ATPase. Bufalin also induces differentiation of leukemia cells
A chemical investigation of Digitalis purpurea seeds led to the isolation of three new cardenolide glycosides (1, 8 and 11), together with 12 known cardenolide glycosides (2-7, 9, 10 and 12-15). The structures of 1, 8 and 11 were determined by 1D and 2D NMR spectroscopic analyses and the results of
