Based on the active ingredient of the drug Ximedon (1,2-dihydro-4,6-dimethyl-1-N-(2-hydroxyethyl)pyrimidone-2, referred below to as pyrimidine (I), novel derivatives containing biogenic acids: succinic, L-ascorbic, para-aminobenzoic, nicotinic, and L-2-amino-4-(methylthio)butanoic (L-methionine) acids have been synthesized. The parameters of acute toxicity (LD₅₀) have been studied. The antitoxic effect of the compounds upon the injury by the hepatotropic poison carbon tetrachloride has been examined as the primary evaluation of their hepatoprotective properties. It has been found that, according to toxicological safety, the compounds synthesized belong to classes III and IV (moderately and little toxic compounds). The conjugates of pyrimidine (I) with ascorbic acid and methionine (LD₅₀ more than 5400 mg/kg) are least toxic. Pyrimidine (I) and its derivatives possess the antitoxic activity upon acute poisoning with carbon tetrachloride; the combined injection of carbon tetrachloride with pyrimidine (I) or its derivatives leads to an increase in the survival of animals and the normalization of the integral functional parameters, weight and body temperature, which decrease upon toxic injury. In addition, pyrimidine (I) and some of its derivatives (conjugates with L-ascorbic, succinic, para-aminobenzoic, and nicotinic acids) decrease the weight coefficients of the liver and kidneys (the organ-to-body-weight ratio) and the activity of transaminases, the markers of hepatic cytolysis, which increase upon toxic injury with carbon tetrachloride. The area of the pathological injury of the liver by steatosis and necrosis decreases by the action of pyrimidine (I) and its novel derivatives (conjugates with L-ascorbic, succinic, and nicotinic acids) two to three times. Advantages of pyrimidine (I) and its novel derivatives over the hepatoprotective drug Thiotriazolin have been revealed.
