Total Synthesis of Cardenolides Acospectoside A and Acovenoside B [PDF]
Acospectoside A (1) and acovenoside B (2), two cytotoxic cardenolides extracted from the venomous South African bush Acokanthera oppositifolia, are distinguished by their unique structural motifs of the l-acovenose moiety at C-3 and a 1β-O-acetylated ...

Cardenolide toxin diversity impacts monarch butterfly growth and sequestration [PDF]
In coevolutionary interactions, host plants accrue novel chemical defenses that specialist herbivores counter by detoxification and sometimes sequestration.

Rotation Conformational Effects of Selected Cytotoxic Cardiac Glycosides on Their Interactions with Na+/K+-ATPase [PDF]
Cardenolides are an important group of steroidal natural products and have been used successfully for the treatment of cardiovascular diseases by targeting Na+/K+-ATPase (NKA) and found more recently to show potential anticancer activity.

New Structures, Spectrometric Quantification, and Inhibitory Properties of Cardenolides from Asclepias curassavica Seeds [PDF]
Cardiac glycosides are a large class of secondary metabolites found in plants. In the genus Asclepias, cardenolides in milkweed plants have an established role in plant–herbivore and predator–prey interactions, based on their ability to inhibit the ...

Substrate Specificity of ABCB Transporters Predicted by Docking Simulations Can Be Confirmed by Experimental Tests [PDF]
ATP-binding cassette (ABC) transporters, particularly those of subfamily B, are involved in cell detoxification, multidrug resistance, drug treatment pharmacodynamics, and also ecological adaptation.

Cardenolides in the defensive fluid of adult large milkweed bugs have differential potency on vertebrate and invertebrate predator Na+/K+-ATPases [PDF]
Aposematic animals rely on diverse secondary metabolites for defence. Various hypotheses, such as competition, life history and multifunctionality, have been posited to explain defence variability and diversity.

Strophanthus sarmentosus Extracts and the Strophanthus Cardenolide Ouabain Inhibit Snake Venom Proteases from Echis ocellatus [PDF]
Strophanthus sarmentosus is recognised for various ethnomedicinal applications, including treatment after snakebites. However, only limited scientific evidence exists on its antivenomous capabilities.

Gut-specific cardenolide-resistant sodium pump primed an omnivore to feed on toxic oleander
Summary: Apocynaceae plants produce toxic cardenolides to defend against their herbivores. Cardenolides could inhibit the α subunit of Na+⁄K+-ATPase (ATPα), which plays critical roles in biological processes such as muscle contraction, neural function ...

Sequestration, that is, the accumulation of plant toxins into body tissues for defense, was predicted to incur physiological costs and may require resistance traits different from those of non‐sequestering insects.
