A number of dicarboxylic N (2 nitroxyalkyl)amides and N (2 nitroxyalkyl)imides were synthesized and their antiischemic activity was studied. The ratio of the areas of necrotic and ischemic zones was used as a criterion for evaluation of antiischemic activity. The maximum values were close to antiischemic activity of Nicorandil, with acute toxicity of compounds synthesized being considerably lower.Key words: reaction of diethyl dicarboxylates with amino alcohols, nitration of oxyalkyl amides and imides with nitric acid and its mixtures with sulfuric acid and acetic anhydride, solutions of nitric acid in chloroalkanes, succinic and citric nitroxyalkylamides, succinic nitr oxyalkylimides, acute toxicity, antiischemic activity.
