INFLUENCE OF NEUROTROPIC AND METABOLIC DRUGS ON STRUCTURAL AND FUNCTIONAL STATE OF LIPID MATRIX OF THE CELL MEMBRANE

Abstract

Lately, more and more often to stimulate the reproductive function of animals people use biochemical products, which are based on neurotropic and metabolic compounds and trace elements of nanobiotechnological origin. In order to new biotechnical drugs search and development, and more effective and safe combinations of dietary supplements in them, one should know Biochemical mechanisms of membranotropic action of these substances on a cell. Since these substances can lead to physiological changes in the cell and trigger nonspecific toxic effects on the body of animals depending on dose and period of action. The article presents the results of studies on the effects of neurotropic and metabolic drugs on structural and functional state of lipid matrix of the cell membrane. In experiment were used four drugs: hlutam 1-M (Sodium Glutaminate), stymulin (Sodium Glutaminate, Sodium Succinate), nanovulin-VHR (Sodium Glutaminate, Sodium Succinate, Copper Citrate), nanovulin-R (Sodium Glutaminate, Sodium Succinate, L-arginine, Copper Citrate). The main task of the experiment was to investigate the concentration effects and primary mechanisms of membranotropic influence of the components of investigated drugs in the range of physiological concentrations of the active substance on the structural and functional state of the lipid matrix of cell membranes. According to research results, it was found that Sodium Glutaminate, which is part of all the investigational drugs, affects the polarity of the hydrophobic zone of the membrane and increases the polarity of the lipid surround. An application of Sodium glutaminate with Succinate in same drug (stimulin, nanovulin-VHR, nanovulin-R) reduces the destructive effects of Sodium Glutamate on the lipid membrane of cells. Also, it should be noted that Copper Citrate in combination with Glutaminate and Succinate (nanovulin-VHR, nanovolin-R) excludes the membrane-stabilizing and membrane-disruptive effects of their influence on the structure of lipid packing in the bilayer. From the results of the research we can suggest, that aquachelates penetrate the hydrophobic lipid bilayer zone, as evidenced by the total fluorescence quenching of pyrene.
