Promising antihypoxant in a range of complex zinc-containing derivatives of nicotinic acid

Abstract

The aim of the work was to study the antihypoxic properties of a number of complex zinc-containing compounds of nicotinic acid under the code πQ. The experiments were performed on male mice of the SHR line. Antihypoxic properties of compounds were studied on 4 models of acute hypoxia (hypoxia with hypercapnia, hypobaric, hemic, and histotoxic). It was found that the compound πQ-1043 in the dose spectrum of 10-100 mg/kg effectively increases the life expectancy of animals in all models of acute hypoxia. The compound πQ-1043 at a dose of 25 mg/kg reduces the oxygen consumption and rectal temperature of animals, which can be a key factor in its anti-hypoxic action. The compound does not change glycolytic carbohydrate metabolism in animals under normal conditions, but corrects these changes in acute hypoxia. Substance πQ-1043 maintains a high content in the blood of erythrocytes and hemoglobin under hypoxic conditions. The lethal dose 50 of the compound πQ-1043 applies to moderately toxic chemicals. It is assumed that the complex zinc-containing derivative of nicotinic acid πQ-1043 is a promising compound for the development of an effective drug for the correction of hypoxic states of different genesis.
