FIELD: chemistry. ^ SUBSTANCE: present invention relates to organic chemistry and specifically to compounds of formula I or to pharmaceutically acceptable salts thereof, where Ar is imidazole or pyrazole, where the said Ar can be substituted with substitute(s) selected from a group consisting of a C1-C6 alkyl group, a phenyl group and a halogen atom, each of Y1, Y2 and Y3 is a carbon ot nitrogen atom, A is an oxygen atom, a sulphur atom or a group of formula -SO2-, R1 is a hydrogen atom, a C1-C6 alkyl group which can be substituted with one phenyl group (where the said phenyl group can be substituted with one substitute selected from a group consisting of a halogen atom and a C1-C6 alkyl group), or a phenyl group, R2 is a C1-C6 alkyl group, R3 is (i) a C1-C18 alkyl group, (ii) C2-C8 alkenyl group, (iii) C2-C8 alkynyl group, (iv) C3-C8 cycloalkyl group, (v) C1-C6 alkyl group substituted with 1-3 substitutes selected from a group given in paragraph 1 of the formula of invention, or (vi) a phenyl group, a naphthyl group, a pyrazolyl group, a pyridyl group, an indolyl group, a quinolinyl group or an isoquinolinyl group, where each of the said groups can be substituted with 1-3 substitutes selected from a group given in paragraph 1, R4 is a hydrogen atom or a C1-C6 alkyl group, and R5 is (i) C1-C10 alkyl group, (ii) C1-C10 alkyl group which is substituted with one or two substitutes selected from a group given in paragraph 1, (iii) C2-C8 alkenyl group which can be substituted with a phenyl group, or (iv) phenyl group, naphthyl group, thienyl group, pyrrolyl group, pyrazolyl group, pyridyl group, furanyl group, benzothienyl group, isoquinolinyl group, isoxazolyl group, thiazolyl group, benzothiadiazolyl group, benzoxadiazolyl group, phenyl group, condensed with a 5-7-member saturated hydrocarbon ring which can contain one or two oxygen atoms as ring members, uracyl group or tetrahydroisoquinolinyl group, where each of the said groups can be substituted with 1-5 substitutes selected from a group given in paragraph 1, provided that when Ar is a group of formula 5, which can be substituted with a C1-C6 alkyl group, R5 is not a C1-C10 alkyl group, and the formula (I) compound is not 5-(3,5-dichlorophenylthio)-4-isopropyl-2-methane-sulfonylaminomethyl-1-methyl-1H-imidazole or 5-(3,5-dichlorophenylthio)-4-isopropyl-1-methyl-2-p-toluene-sulfonylaminomethyl-1H-imidazole. The invention also relates to a pharmaceutical composition based on the formula I compound and to formula II compounds, radicals of which are defined in the formula of invention. ^ EFFECT: obtaining novel compounds with inhibitory effect on the bond between S1P and its Edg-1 (SIP1) receptor. ^ 32 cl, 43 tbl, 18 ex |
