Protective properties of the nickel (II) complex with tryptophan

Abstract

Aim. The synthesized and characterized of the complex nickel (II) with tryptophan [NiL2 (H2O)2]; L = Trp. It is shown that the composition of the complex obtained depends on the ratio of the initial components. Methods. The composition and structure of the complex were studied by elemental, TG/DrTG-DTA analysis and IR spectroscopy. The method of IR showed that the ligand in the composition of the metal complex enter the neutral form and coordinate with the complexing agent through the nitrogen atom. Results. The results of thermogravimetric studies have shown that the final product of the thermal decomposition of all compound is metal oxide, respectively. Conclusions. Have been studied the biological properties – the toxicity has been evaluated, the influence of the complex on the resistance to hypoxia and ant radiation activity has been determined.
 Keywords: tryptophan, nickel, tryptophan-metal complexes, amine groups, IR spectroscopy, thermogravimetry, toxicity, antiradiation activity.

Protective effect of zinc complex with hypoxanthine-9-riboside on wheat seedlings grown from gamma-irradiated seeds

“…A small number of works are devoted to the study of the formation of the photosynthetic apparatus, with the participation of metal complexes. In works [9][10][11][12][13], devoted to the study of defense mechanisms in plants, synthetic and natural substances are widely used that increase the vital activity of the body, restore metabolism, and eliminate genetic damage caused by irradiation. When studying the effect of salts of some metals on living organisms, their preventive and therapeutic effects were revealed [14][15].…”
