Abstract
“Double” derivatives of the drug Xymedon (1,2-dihydro-4,6-dimethyl-1-N-(hydroxyethyl)pyrimidone-2), hereafter referred to as pyrimidine (I), in which the pyrimidine (I) molecules are joined by an alkyl(xylylenyl)dionate bridge have been synthesized. Primary data on the hepatoprotective activity of five “double” pyrimidine (I) derivatives with different numbers of methylene groups and a meta-xylylene fragment in the ester bridge have been obtained on normal human hepatocytes of the Chang Liver cell line. The cytotoxicity and the cytoprotective properties of the new compounds against the background of exposure to d-galactosamine at a concentration of 150 mmol/L have been determined, their effect on the cell cycle compared with that of the initial pyrimidine (I) has been studied, and the dependence of the biological properties of the derivatives on their structure has been established.
