Hydrogenation of ecdysteroids

Steroids, 2012
Catalytic hydrogenation is extensively used in steroid chemistry. The interest in transformations to the steroid skeleton of ecdysteroids has been increasing in the past years. Essential interest in the chemistry of ecdysteroids is caused by the selective reduction of Δ7 bond with the formation of 7,8-dihydro analogues, because this process allows one ...

Ecdysteroids in nematodes

Parasitology Today, 1990
The occurrence of ecdysteroids (insect moulting hormones) in nematodes, albeit at low concentrations, has been firmly established. In addition to apparently stimulating moulting in a few species, exogenously applied ecdysteroids have now been shown to have interesting biological effects on meiotic reinitiation in oocytes and on microfilarial production

An extensive ecdysteroid CoMFA

Journal of Computer-Aided Molecular Design, 1999
The ecdysteroid agonist activity of 71 HPLC-purified ecdysteroids was measured in the Drosophila melanogaster BII tumorous blood cell line assay. The resultant log(ED50) values, spanning almost 6 orders of magnitude, were used to construct a comparative molecular field analysis (CoMFA) model in which conformations were selected by homology to the ...

Spinat und Ecdysteroide

Ernährung & Medizin, 2023
Spätestens mit der Comic-Figur Popeye gilt Spinat als kraftbringend und leistungssteigernd. An seiner anabolen Wirkung scheint tatsächlich etwas dran zu sein. Im Fokus der Wissenschaft stehen die im Spinat enthaltenen Ecdysteroide.
