Naturally occurring cardenolides affecting Schistosoma mansoni

open access: yes, 2020
Schistosomiasis is a neglected tropical disease of considerable public health burden. We recently discovered a micromolar activity of several cardenolides against newly transformed schistosomula (NTS) of the parasitic flatworm; Schistosoma mansoni; in a ...

Antiproliferative activity of cardenolides isolated from Streptocaulon juventas

open access: yes, 2003
Sixteen cardenolides, two hemiterpenoids, two phenylpropanoids and a phenylethanoid isolated from the roots of Streptocaulon juventas (LOUR.) MERR. were examined for their antiproliferative activity toward three human-derived (HT-1080 fibrosarcoma, lung ...

Antiproliferative cardenolides from Periploca graeca

open access: yes, 2007
Nine cardiotonic steroids, six 17β-cardenolides (2, 4, 6-9) and three 17α-cardenolides (1, 3, 5) have been identified from the chloroform and chloroform-methanol exts. of Periploca graeca L. (Asclepiadaceae) stems. Among these, compd.

Detection of Residues of Cardenolides of Nerium oleander by High-Performance Thin-Layer Chromatography in Autopsy Samples [PDF]

open access: yes, 2013
Background: Nerium oleander is an evergreen shrub of Apocynaceae family cultivated worldwide as an ornamental plant. All parts of the plant are toxic and contain a mixture of very toxic cardiac glycosides of cardenolides. A number of techniques were used

Utility of Cyclodextrin in Mobile Phase for High Performance Liquid Chromatographic Separation of Cardenolides

open access: yes, 1988
Cyclodextrin was used as a component of mobile phase for the separation of cardenolides by reversed-phase high performance liquid chromatography. The addition of y-cyclodextrin to the mobile phase improved the separation of isomeric cardenolides.

Interspecific variation and elevated CO2 influence the relationship between plant chemical resistance and regrowth tolerance

open access: yesEcology and Evolution, 2020
To understand how comprehensive plant defense phenotypes will respond to global change, we investigated the legacy effects of elevated CO2 on the relationships between chemical resistance (constitutive and induced via mechanical damage) and regrowth ...

Does chemistry make a difference? Milkweed butterfly sequestered cardenolides as a defense against parasitoid wasps

open access: yes, 2019
Plant allelochemicals have important roles in plant defense as well as ecological and co-evolutionary dynamics within tri-trophic systems of plants, herbivores, and natural enemies.
