FIELD: chemistry.
SUBSTANCE: invention relates to novel atropoisomers of formula , in which R and R1 each independently represents hydrogen or methyl; R2, R3 and R4 each independently represents hydrogen or trifluoromethyl, on condition that R2, R3 and R4 all do not represent hydrogen; and R5 represents bromine, chlorine; or to its non-toxic pharmaceutically acceptable salt, solvate. Invention also relates to pharmaceutical composition, as well as to method of treatment.
EFFECT: obtaining novel biologically active compounds, possessing properties which open calcium-activated potassium channels of high conductivity.
