Synthesis of Analogues of (+)-Gomphoside, a Potent HIF-1 Inhibitor and Cardenolide

open access: yesNatural Product Communications, 2018
The milkweed bush Gomphocarpus fruticosus R.Br. found in Australia contains the steroidal glycoside (+)-gomphoside, its derivatives (-)-3'-dehydrogomphoside and (+)-3'- epi -gomphoside, as well as other glycoside compounds. The key structural features of

The Qualitative Identification of Cardenolide-Containing Plants Using Ultra High Performance Liquid Chromatography – High Resolution Mass Spectrometry Chromatograms at Select Ions [PDF]

open access: yes, 2023
Cardiac glycosides (CGs), classified as cardenolides or bufadienolides, are toxins found in a variety of flora and fauna. CGs have historically been used to treat heart failure, but despite their place in medicine, they are still toxic to humans and ...

12β,14-Dihydroxy-3-oxo-5β,20(22)-cardenolide monohydrate

open access: yesActa Crystallographica Section E, 2010
The title compound, digoxigenone, C23H30O5·H2O, was biotransformed from digoxigenin. In the crystal, intermolecular O—H...O hydrogen bonds contribute to the formation of a three-dimensional supramolecular structure.

Nucleolus and c-Myc: potential targets of cardenolide-mediated antitumor activity. [PDF]

open access: yes, 2008
The use of cardenolides like ouabain, digitoxin, or oleandrin has been reported previously many times as a means of potentially combating human refractory prostate cancer by inducing apoptosis through an increase in intracellular calcium concentrations ...

Total Synthesis of Cardenolides Acospectoside A and Acovenoside B

open access: yesMolecules
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 ...

Data from: Substitutions in the cardenolide binding site and interaction of subunits affect kinetics besides cardenolide sensitivity of insect Na,K-ATPase

open access: yes, 2017
Substitutions within the cardenolide target site of several insects' Na,K-ATPase α-subunits may confer resistance against toxic cardenolides. However, to which extent these substitutions alter the Na,K-ATPase's kinetic properties and how they interact ...

New cardenolide glycosides from the defence glands of Chrysolinina beetles (Coleoptera :Chrysomelidae)

open access: yes, 1988
The composition of the defence secretions of six species of chrysomelid beetles (Chrysolina polita, C. americana, C. grossa, C. herbacea, C. fastuosa, and Oreina gloriosa) belonging to the sub‐tribe Chrysolinina has been investigated.

HPLC analysis of cardenolide induction in Asclepias syriaca leaves and nectar following application of jasmonic acid

open access: yes, 2013
iv, 25 p.Plants produce an array of secondary defense compounds to combat herbivory. However, secondary compounds in nectar seem to serve a paradoxical function, since nectar is commonly used to attract insect pollinators.

21-Benzylidene digoxin: a proapoptotic cardenolide of cancer cells that up-regulates Na,K-ATPase and epithelial tight junctions.

open access: yesPLoS ONE, 2014
Cardiotonic steroids are used to treat heart failure and arrhythmia and have promising anticancer effects. The prototypic cardiotonic steroid ouabain may also be a hormone that modulates epithelial cell adhesion. Cardiotonic steroids consist of a steroid

The Evolution of Cardenolide-Resistant Forms of Na +,K +-Atpase in Danainae Butterflies

open access: yes, 2012
Cardenolides are a class of plant secondary compounds that inhibit the proper functioning of the Na +, K +-ATPase enzyme in susceptible animals. Nonetheless, many insect species are able to sequester cardenolides for their own defence.
