Autor: Ya. V. Khamiuk, R. P. Litvinovskaya, A. P. Kolbas
Publikováno v: Proceedings of the National Academy of Sciences of Belarus, Biological Series. 67:181-189
A step-by-step study of the biological activity of 24-epibrassinolide (EB) and its sodium salts of esters with sulfuric acid (sodium 2-, 3-, 22and 23-monosulfates and disodium 2.3-disulfate EB) was carried out in experiments on the effect on the grow

Analysis of NMR Spectral Data of Structural Analogs of Ponasterone α and 9α,20-Dihydroxyecdysone with an Isoxazoline Ring in the Side Chain
Autor: R. P. Litvinovskaya, A. V. Baranovsky
Publikováno v: Journal of Applied Spectroscopy. 88:483-488
Resonances of H and C atoms in isoxazolinyl steroids, i.e., structural analogs of ponasterone A and 9α,20-dihydroxyecdysone, were assigned by two-dimensional NMR spectroscopy. Characteristic effects of neighboring functional groups on the chemical s
