Cardiac glycosides isolated from the Indian-snuff, Maquira sclerophylla Ducke
Memorias do Instituto Oswaldo Cruz, 1991 The hydroalcoholic extract of the powdered bark of the Indian-snuff Maquira sclerophylla Ducke was purified by column chromatography in silica-gel and the major cardenolide isolated from preparative TLC was identified by 1H-NMR, 1 2 C-NMR and IR analyses.

Cardiac Glycosides in Human Physiology and Disease: Update for Entomologists
Insects, 2019 Cardiac glycosides, cardenolides and bufadienolides, are elaborated by several plant or animal species to prevent grazing or predation. Entomologists have characterized several insect species that have evolved the ability to sequester these glycosides in

Convergent Total Synthesis of 16β‐Hydroxylpseudobufarenogin
Angewandte Chemie International Edition, EarlyView.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 ...

Using genetic data to predict the vulnerability of a native predator to a toxic invader [PDF]
, 2016 Australia has no native toad species, and as a consequence, many Australian predators lack resistance to the toxins of the invasive cane toad Rhinella marina, and die if they ingest one of these toads.

Nano Select, Volume 7, Issue 3, March 2026.ABSTRACT The green synthesis of metal oxide nanoparticles (MONPs) using plant‐based resources has gained significant traction as an environmentally benign, cost‐effective, and scalable alternative to traditional chemical and physical methods. This review comprehensively explores the plant‐mediated synthesis routes for a variety of MONPs, including CuO,

Endophytic fungi from Nerium oleander L (Apocynaceae): Main constituents and antioxidant activity [PDF]
, 2007 Diverse endophytic fungi exist within plant aerial tissues, with a global estimate of up to a million undescribed species. These endophytes constitute a rich bio-resource for exploration to discover new natural products.

Ouabain‐induced hypertension in rats: Mechanisms, variability and translational implications
Experimental Physiology, Volume 111, Issue 3, Page 653-673, 1 March 2026.Abstract Ouabain‐induced hypertension is a multifactorial and condition‐dependent phenomenon involving coordinated actions across vascular, renal and central nervous system pathways. At the vascular level, ouabain inhibits Na⁺/K⁺‐ATPase, particularly the α2‐isoform, leading to elevated intracellular Ca2⁺, enhanced vasoconstriction and structural ...
