The Absolute Configuration at C24 of the Ecdysteroids Dacrysterone, Pterosterone and Ponasterone C

, 1979
The shielding values in 13C N.M.R. spectra of the ecdysteroids dacrysterone, pterosterone, and ponasterone C have been assigned, together with those for the 20,22- and 22,24-benzylidene acetal derivatives of the latter. From the N.M.R.

Occurrence of free ecdysteroids and yolk protein ecdysteroid conjugates in the embryo of the melon fly, Dacus cucurbitae Coquillet [PDF]

, 1990
The titer of ecdysteroids occurring in the embryos of the melon fly, Dacus cucurbitae Coquillet was determined at each developmental hour by radioimmunoassay. Free ecdysteroids were extracted from eggs in 60% methanol which showed one single peak at 18 h

C-29 Ecdysteroids from Ajuga reptans var. reptans

, 2016
Investigation of the ecdysteroid constituents of the herb Ajuga reptans var. reptans resulted in the isolation of three new ecdysteroids, named reptanslactone A (2), reptanslactone B (3), and sendreisterone (5), and the known 24-dehydroprecyasterone (1 ...

[Ecdysteroids of Silene italica ssp. nemoralis, novel approaches of ecdysteroid therapy].

Acta pharmaceutica Hungarica, 2006
Ecdysteroids are known as insect moulting hormones. They have the basic steroid structure, although their physiological effects on mammalians do not show the thymolytic and androgenic side effects of vertebrate type steroid hormones. At the same time, phytoecdysteroids can be used utilizing their anabolic and adaptogenic effects. Ecdysteroids also have
