FIELD: chemistry. ^ SUBSTANCE: invention relates to novel compounds of formula I ^ in form of a salt, where R1 and R2 each independently denotes phenyl, where one or both R1 and R2 are substituted in one, two or three positions by the following groups: halogen, C1-C8alkyl or C1-C8alkoxy, and R3 is hydroxy, or R1 and R2 each denotes an unsubstituted phenyl, and R is hydrogen, C1-C8alkyl, C1-C8alkoxy or C1-C8alkylthio, or R1 is C3-C8cycloalkyl and R2 is phenyl or a 5-member heterocycle containing at least one heteroatom in the ring selected from a group which includes oxygen and sulphur, and R3 is hydroxy, or -CR1R2R3 denotes 9-hydroxy- 9H-fluoren-9-yl or 9-hydroxy-9H-xanthen-9-yl, and R4 is C1-C8alkyl substituted in one, two or three positions by a -CO-N(R5)R6 group, where R5 is hydrogen and R6 is a 5-member heterocycle containing at least one heteroatom in the ring selected from a group which includes nitrogen and oxygen, optionally substituted with phenyl, or R1 and R2 each denotes an unsubstituted phenyl, and R3 is hydroxy and R4 is C1-C8alkyl substituted in one, two or three positions by a -CO-N(R5)R6 group, where R5 is hydrogen and R6 is 5-methyl-3-isoxazolyl or R1 and R2 each denote unsubstituted phenyl, and R3 is hydroxy and R4 is 1-ethyl substituted in one, two or three positions by a -CO-N(R5)R6 group, where R5 is hydrogen, R6 is a 5-member heterocycle containing at least one heteroatom in the ring selected from a group which includes nitrogen and oxygen, provided that the formula I compound is not (R)-3-(2-hydroxy-2,2-dithiophen-2-ylacetoxy)-1-(pyrazin-2-ylcarbamoylmethy)-1-azoniumbicyclo[2.2.2]octane, (R)-3-(2-hydroxy-2,2-dithiophen-2-ylacetoxy)-1-(isoxazol-3-ylcarbamoylmethyl)-1-azoniumbicyclo [2.2.2]octane bromide or (R)-3-(2-hydroxy-2,2-dithiophen-2-ylacetoxy)-1-(pyrimidin-4-ylcarbamoylmethyl)-1-azoniumbicyclo [2.2.2]octane bromide. The invention also relates to a pharmaceutical composition, to use of compounds in any of claims 1-8, as well as to methods for synthesis of formula I compounds. ^ EFFECT: obtaining new biologically active compounds which have M3 muscarinic receptor mediated activity. ^ 14 cl, 254 ex, 1 tbl |
