FIELD: chemistry.SUBSTANCE: invention relates to organic chemistry, particularly to novel carboxamide compounds of formula and to pharmaceutically acceptable salts thereof, where R1 is phenyl-C1-C6-alkyl, where the phenyl can be unsubstituted or substituted with 1 radical R1c; where R1c is independently selected from halogen, C1-C6-alkyl, C1-C6-alkoxy, where the C1-C6alkyl groups can be partially or completely halogenated or can have 1, 2 or 3 substitutes R1a, and -(CH2)p-NRc6Rc7, where p=0, 1, where R1a is independently selected from NRa6Ra7, Ra6 is C1-C6-alkyl, Ra7 is C1-C6-alkyl, or two radicals Ra6 and Ra7, or Rc6 and Rc7 together with a N atom form a nitrogen-containing 6-member saturated heterocycle, which can optionally have 1 additional O heteroatom as a ring member, R2 is phenyl, pyridyl, where the phenyl can be unsubstituted or can have 1 substitute R2c; where R2c has one of the values given for R1c; R3 is C1-C6-alkyl, C3-C6-alkenyl, C3-C6-cycloalkyl, C3-C6-cycloalkyl-C1-C2-alkyl, where C1-C6alkyl, is unsubstituted or has 1 substitute Rxa, where Rxa has one of the values given for R1a; R5 is a halogen or C1-C2-alkyl, where m equals 0 or 1; n equals 0. The invention also relates to specific compounds and a pharmaceutical composition based on the compound of formula (I).EFFECT: obtaining novel carboxamide compounds which are useful as calpain inhibitors (calcium-dependent cysteine proteases).27 cl, 4 tbl, 34 exИзобретение относится к области органической химии, а именно к новым карбоксамидным соединениям формулы (I) и к их фармацевтически приемлемым солям, где R1 является фенил-С1-С6-алкилом, где фенил может быть незамещенным или замещенным 1 радикалом R1c; где R1c выбирают независимо из галогена, С1-С6-алкила, C1-C6-алкокси, где С1-С6алкильные группы могут быть частично или полностью галогенированы или могут иметь 1, 2 или 3 заместителя R1a, и -(CH2)p-NRc6Rc7, где р=0, 1, где R1a выбирают независимо из NRa6Ra7, Ra6 представляет собой С1-С6-алкил, Ra7 пре
