An androstane bioside and 3'-thiazolidinone derivatives of doubly-linked cardenolide glycosides from the roots of Asclepias tuberosa.

Steroidal compounds in the roots of Asclepias tuberosa were investigated and 17alpha-hydroxyandrosta-4,6,15-trien-3-one 17-O-alpha-L-arabinopyranosyl-(1-->6)-beta-D-glucopyranoside, termed ascandroside, was isolated from the CHCl3-soluble fraction. Among five doubly-linked cardenolide glycosides, two were identified as 3'-spiro-linked thiazolidinone (4) and S-oxythiazolidinone derivatives (5) o...

Fine-tuning of defences and counter-defences in a specialised plant–herbivore system

1. The plant–herbivore arms race has been postulated to be amajor driver for generating biological and biochemical diversity on Earth. Herbivore feeding is reduced by the production of chemical and physical barriers, but increases plant resistance against subsequent attack. Accordingly, specialisation is predicted to be an outcome of herbivores being able to circumvent plant-induced defences. 2...

Cardenolide and oxypregnane glycosides from the root of Asclepias incarnata L.

Twenty-nine new oxypregnane glycosides were obtained along with two known cardenolides, frugoside and gofruside, and three known 12-O-acylated pregnane glycosides from the roots of Asclepias incarnata L. (Asclepiadaceae). By detailed studies of the 1H- and 13C-NMR spectra, the structures were determined to be tri- to penta glycosides of isolineolon, 12-O-acetyllineolon, ikemagenin, 12-O-benzoyl...

Steroidal glycosides from the roots of Asclepias curassavica.

Twenty-six new acylated-oxypregnane glycosides were obtained along with three known cardenolide glycosides from the roots of Asclepias curassavica (Asclepiadaceae). The new compounds were confirmed to contain 12-O-benzoylsarcostin, 12-O-benzoyldeacylmetaplexigenin, kidjolanin, and 12-O-benzoyltayloron, and one new acylated-oxypregnane, 12-O-(E)-cinnamoyltayloron, as their aglycones, using both ...
