Pro-apoptotic and cytostatic activity of naturally occurring cardenolides

, 2009
Cardenoliddes are steroid glycosides which are known to exert cardiotonic effects by inhibiting the Na+/K+-ATPase. Several of these compds. have been shown also to possess anti-tumor potential.

The Effect of Ultra-Violet Irradiation on Cardenolides

, 1957
Solutions of digoxin, digoxigenin and digitoxigenin in ethanol were subjected to ultra-violet irradiation in the absence of oxygen. Chromatographic analysis showed that the starting material was transformed into several other compounds some of which may ...

THEVETOSIDE AND DIGITOXIGENIN, CARDENOLIDES FROM 2 SPECIES OF THEVETIA (APOCYNACEAE)

, 1993
In a comparative analysis of the cardenolides of two Thevetia species, T. ovata Cav. and T thevetioides HBK, the amount of thevetoside in the seeds, and its acetate, was determined, as well as the yield of digitoxigenin obtained from these monoglycosides.

Cardenolides, induced responses, and interactions between above- and belowground herbivores of milkweed (Asclepias spp.). Ecology 90:2393–404

, 2009
. Theory has long predicted allocation patterns for plant defense against herbivory, but only recently have both above-and belowground plant defenses been considered simultaneously. Milkweeds in the genus Asclepias are a classic chemically defended clade
