FIELD: chemistry.
SUBSTANCE: present invention relates to novel 3,4-substituted pyrrolidine derivatives of general formula 
or pharmaceutically acceptable salts thereof, where R1 is an acyl selected from values given paragraph 1 of the formula of invention; R2 is unsubstituted C1-C4-alkyl or C3-C7-cycloalkyl; R3 is a fragment selected from a group of fragments of formulae: 
(a), 
(b),
(c) and 
(f), where any of the fragments of formulae given above (a), (b) and (f), the star (*) indicates a bond of the corresponding fragment R3 with the molecule residue in formula I; Ra denotes N-C1-C4-alkylaminocarbonyl, N-phenylaminocarbonyl, N-(phenyl-C1-C4-alkyl)aminocarbonyl, N-(C1-C4-alkyl)-N-(phenyl-C1-C4-alkyl)aminocarbonyl, N-(C3-C7-cycloalkyl- C1-C4-alkyl)-N-(phenyl-C1-C4-alkyl)aminocarbonyl, N-(C1-C4-alkyl)-N-(C3-C7-cycloalkyl-C1-C4-alkyl)aminocarbonyl, N,N-di-(C1-C4-alkyl)aminocarbonyl, N-(C3-C7-cycloalkyl)-N-(phenyl-C1-C4-alkyl)aminocarbonyl, N-(C3-C7-cycloalkyl)-N-(tetrahydropyranyl-C1-C4-alkyl)aminocarbonyl, N-(C3-C7-cycloalkyl)-N-(tetrahydropyranyl)aminocarbonyl or hydrogen; Rb and Rc are independently selected from a group comprising unsubstituted C1-C4-alkyl, unsubstituted monocyclic aryl, unsubstituted monocyclic heterocyclyl, unsubstituted or substituted monocyclic C3-C7-cycloalkyl, unsubstituted aryl- C1-C4-alkyl, usubstituted monocyclic C3-C7-cycloalkyl- C1-C4-alkyl, hydrogen or acyl, where the acyl is selected from values given in paragraph 1 of the formula of invention; or Rb and Rc together may form a 6-member nitrogen-containing ring which may be unsubstituted or disubstituted with =O; Rd in the fragment of formula (c) denotes a phenyl or phenyl-C1-C4-alkyl; Re denotes hydrogen or C1-C4-alkyl; and m equals 2; each of R4 and R5 denotes hydrogen; and T denotes methylene. The invention also relates to the pharmaceutical composition based on the compound of formula I and a method of treating hypertension using the compound of formula I.
EFFECT: novel pyrrolidine derivatives having renin inhibiting activity are obtained.
