BENZOXAZEPIN DERIVATIVES, THEIR PRODUCTION METHOD, MEDICINE BASED ON THEM, AND THEIR APPLICATION

FIELD: chemistry, pharmacology. ^ SUBSTANCE: compound of formula [I]: is described, where the ring A represents halogen substituted benzene ring; the ring B represents benzene ring substituted with two lower, 1 to 4 carbon atoms, alcoxy-groups; the ring C represents benzene ring or five-member aromatic heterocyclic ring, that may be optionally substituted with substitute as follows: carboxyl group, C1-4-alkyl group, C2-7-alkanoiloxy-C1-6-alkyl group, phenyl-C1-4-alkyl group, phenyl group, optionally substituted with carboxyl group, or oxo-group; R1 represents C1-6-alkyl group, optionally substituted with hydroxyl group, that optionally substituted with C2-20-alkanoil or C1-7-alkyl group; X1a represents bound or C1-6-alkylen, optionally substituted with hydroxyl or oxo-group; X1b represents bound or C1-6-alkylen, optionally substituted with hydroxyl or oxo-group; X2 represents bound, -O- or -S- ; X3 represents bound or group, formed by one hydrogen atom elimination from either straight or branched chain C1-7-alkyl, or C2-6-alkenyl group, that optionally substituted with hydroxyl or oxo-group; and Y represents optionally etherified carboxyl group; or its salt. Benzoxazepin derivatives production method, medicine based on them, and their application are also described. ^ EFFECT: novel compounds have high lipids-decreasing effect and are helpful as hyperlipidemia prevention and treatment medicine. ^ 20 cl, 168 ex
