New Ecdysteroids From Serratula tinctoria
Planta Medica, 1992 Six new ecdysteroids have been isolated from Serratula tinctoria; these are: the 2,22- and 3,22-diacetates of 20-hydroxyecdysone, 5β-hydroxyrubrosterone, 3-epi-poststerone, 3-epi-rubrosterone, and 22-oxo-20-hydroxyecdysone.

Ecdysteroids From the Underground Parts of Rhaponticum acaule (L.) DC [PDF]
Phytochemistry, 2020 In addition to two known ecdysteroids, 20-hydroxyecdysone and turkesterone, three previously undescribed stigmastane-type ecdysteroids were isolated from the underground parts of Rhaponticum acaule (L.) DC.

Impact of Cadmium on the Ecdysteroids Production in Gammarus fossarum
Ecotoxicology, 2016 International audienceGammarus fossarum is an important test organism which is currently used as a bio-indicator as well as in ecotoxicological tests. Nevertheless, data on ecdys- teroids in endocrine toxicity test are not yet available for these species,

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

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 ...

Several reviews devoted to various aspects of ecdysone research have been published during the last few years. Therefore, this article concentrates mainly on the considerable progress in ecdysone research observed recently, and will cover the results obtained during the last 2 years.

An extensive ecdysteroid CoMFA
Journal of Computer-Aided Molecular Design, 1999The 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 ...
