Difference-perturbation spectra of iodotyrosines and iodothyronines in polyethyleneglycols

The difference-perturbation absorption spectra of monoiodotyrosine, diiodotyrosine, triiodothyronine, and thyroxine with low- and high-molecular-mass polyethyleneglycols as perturbants have been measured and characterized. The SDP spectra, and their intensity and the position of the main maximum depend on the number of iodine atoms and the state of ionization of the hydroxyl in accordance with their electron-accepting properties.Institute of Physiology, Uzbek SSR Academy of Sciences, Tashkent.

Synthesis,structure, and action of some gossypol derivatives on the peroxidation of the lipids of biosubstrates

The synthesis has been effected of new gossypol derivatives using piperidino-and morpholinoethylamines. According to their PMR spectra, these substances exist in the keto-amine form. Their action on the peroxidation of lipids (POL) of various biosubstrates has been studied. Gossypol bis(piperinoethylimine) and bis(morpholinoethylimine) in concentrations of 1·10⁻⁷–5·10⁻⁶ mM exert a pronounced antioxidant action on human blood serum and rat brain synaptosomes. In the same concentrations, these substances suppressed the POL in enzymatic and nonenzymatic systems of the oxidation of rat liver microsomes. A. S.
