Coordination compounds of essential microelement germanium(IV) with metals (Mg, Na, K, Ca, Cu, etc.) and organic ligands -biocatalysts, antidotes at intoxications and regulators of mineral metabolism in living organism (nicotinic, citric, tartaric, 1-hydroxyethylidendiphosphonic acids, nicotinamide) are synthesized for the first time on the Department of General Chemistry and Polymers of Odessa Mechnikov National University. The favorable activity of the synthesized compounds on cardiovascular and chronic respiratory diseases, senile pneu-on cardiovascular and chronic respiratory diseases, senile pneumonia, neuropsychiatric and metabolic disorders, ischemic heart diseases, etc. is described. Thus, the influence of 1-hydroxyethylidendiphosphonatogermanate (medgerm) on CNS, its anxiolytic activity and absence of both hypnotic and myorelaxant effects has been shown. Cardioprotector properties of magnesium hydroxyethylidendiphosphonategermanate as a potential effective and safe drug with the high antihypertensive and antiarrhythmic activity have been found out. The interferoninductive and immunostimulatory activity of germanium(IV) compounds with 1-hydroxyethylidendiphosphonic, nicotinic acids, nicotinamide, pyracetam has been studied. Injection of these drugs (concentration 100-125 μg/ml) causes the 100 % delay of cytopathic action of vesicular stomatitis virus in the cell cultures that demonstrates the ability of compounds to increase essentially cells stability. The perspectives of germanium coordination compounds as interferon inductors and as immune pharmaceuticals for prevention the disbalance of the immune system are reviewed.
Досëіджено впëив ãідразиду ізонікотинової кисëоти, ізонікотиноїëãідразонів 4-диметиëамінобенз-. , 2-ãідроксибенз-, 2-ãідрокси-1-нафтаëьдеãідів та новиõ компëексів стануму(IV) на основі переëічениõ споëук на ріст тест-штамів умовно-патоãенниõ бактерій Staphylococcus aureus, Micrococcus luteus, Proteus vulgaris, Pseudomonas aeruginosa. Показано, що досëіджені споëуки в концентраціяõ 25, 50 та 100 мкã/мë здатні неãативно впëивати на ріст бактерій. Найбіëьш активними щодо біëьшості мікроорãанізмів виявиëися ізонікотиноїëãідразон 2-ãідрокси-1-нафтаëьдеãіду та компëекс стануму(IV) на йоãо основі, які за концентрації 50 мкã/мë та 100 мкã/мë відповідно практично повністю приãнічують ріст умовнопатоãенниõ бактерій. Найчутëивішим до поõідниõ ізонікотинової кисëоти та компëексів стануму(IV) на їõ основі є штам Proteus vulgaris. К ë ю ч о в і с ë о в а : ãідразид, ізонікотиноїëãідразон, компëекси стануму(IV), умовно-патоãенні бактерії, антимікробний ефект.
