Desert Milkweed (Asclepias erosa) as a Midsummer Resource for Arthropod Communities in the Great Basin Desert [PDF]

Ecol Evol
BLURB FOR ETOC: In the Great Basin Desert, many plants senesce as heat and drought intensify in midsummer, potentially concentrating arthropods on the few species that remain physiologically active. We surveyed arthropods on desert milkweed (Asclepias erosa) during this period and recorded 1779 individuals representing 67 morphospecies across 41 plants;

Cardenolide-Engineered Extracellular Vesicles Augment Drug Uptake and Cytotoxicity in Non-small Cell Lung Cancer Cells. [PDF]

Small Methods
Cardenolide‐functionalized extracellular vesicles enable targeted delivery of the chemotherapeutic doxorubicin to A549 lung cancer cells by binding Na+/K+‐ATPase, which is overexpressed in these cells. Surface‐modified, drug‐loaded EVs exhibit enhanced cytotoxicity compared to unmodified EVs and free drug, suggesting this system may lower the effective

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

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.

Convergent Total Synthesis of 16β‐Hydroxylpseudobufarenogin

Angewandte Chemie, Volume 138, Issue 23, 1 June 2026.
We present a novel convergent strategy that integrates Pd/Ag‐promoted Suzuki–Miyaura coupling with Ir‐catalyzed radical‐relay cyclization, enabling the first total synthesis of 16β‐hydroxylpseudobufarenogin. This approach is broadly applicable to the total synthesis of various oxygenated bufadienolides by simply modifying the fragment structures ...

Antiproliferative activity of cardenolides isolated from Streptocaulon juventas

, 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 ...

Aphid Resistance Segregates Independently of Cardenolide and Glucosinolate Content in an Erysimum cheiranthoides (Wormseed Wallflower) F2 Population

Plants
Plants in the genus Erysimum produce both glucosinolates and cardenolides as a defense mechanism against herbivory. Two natural isolates of Erysimum cheiranthoides (wormseed wallflower) differed in their glucosinolate content, cardenolide content, and ...

Natural cardenolides suppress coronaviral replication by downregulating JAK1 via a Na(+)/K(+)-ATPase independent proteolysis

, 2020
[[abstract]]An unprecedented biological function of natural cardenolides independent of their membrane target Na(+)/K(+)-ATPase is disclosed. Previously, we reported that cardenolides impart anti-transmissible gastroenteritis coronavirus (anti-TGEV ...

Integrated Analysis of Grapevine Responses to Winter Pruning Reveals Temperature‐Associated, Polyphenol‐Rich Xylem Occlusions

Plant, Cell &Environment, Volume 49, Issue 12, Page 10533-10547, December 2026.
ABSTRACT Perennial crops are continually wounded throughout cultivation. To limit pathogen infection and tissue dehydration, plants have evolved a range of wound responses that protect damaged tissues. These responses include changes in gene expression and the synthesis of protective compounds such as polyphenols.
