FIELD: organic chemistry. SUBSTANCE: invention proposes derivatives of cycloalkyl-substituted glutaric acid amide of the general formula (I): where: A - (CH2)4,(CH2)5; R1- - H, (C1-C4)-alkyl; R and R4 - H, (C1-C4)-alkyl, (C3-C7)-cycloalkyl, benzyl or biolabile ester-forming group; Y - simple bond, (C1-C6)-alkylene; R2- - H, phenyl, R6CONR5- or R7NR5CO-; R3 means group of formula (II), or their pharmaceutically acceptable salts or biolabile ester. Invention proposes also pharmaceutical composition that inhibits activity of angiotensin-converting enzyme and neutral endopeptidase based on compounds of the formula (I) . EFFECT: improved method of synthesis. 14 cl, 15 tbl
