DERIVATIVES OF TETRAHYDROCARBAZOLES, METHOD OF OBTAINING THEM AND PHARMACEUTICAL COMPOSITIONS CONTAINING THEM

FIELD: medicine. ^ SUBSTANCE: invention relates to compounds of general formula (I) and their pharmaceutically acceptable salts and pharmaceutically acceptable asters, possessing activity with respect to LXR and/or LXR receptors. Compounds can be applied for treatment and prevention of diseases mediated by LXR and/or LXR receptors, namely: increased level of lipids and cholesterol level, atherosclerotic diseases, diabetes, metabolic syndrome, dyslipidermia, sepsis, inflammatory diseases, pancreatitis, liver cholestasis/fibrosis, and diseases which include inflammatory component, such as Alzheimer's disease and reduced/improvable cognitive function. In general formula n represents integer number from 0 to 3; R1 is independently selected from group consisting of halogen, -CN, -NO2, -SO2Me, lower alkyl, -OR11, pyperidinyl and -N(R11)(R11), where R11 is independently selected from lower alkyl and H, X1, X2, X3 and X4 are independently selected from nitrogen and carbon, on condition that, not more than two of X1, X2, X3 and X4 can simultaneously represent nitrogen, and in case when two of X1, X2, X3 and X4 represent nitrogen, n represents 0,1 or 2; k represents integer number 0 or 1; R2 represents H; R3 represents H, lower alkyl or halogen; R4 represents aryl, heteroaryl, lower alkylaryl or lower alkylheteroaryl, each of which is optionally substituted with substituents in amount from one to five, which are independently selected from group consisting of halogen, lower alkyl, -OR41, lower alkinyl and NR42R43, where R41 represents lower alkyl, R42 and R43 independently on each other represent hydrogen or lower alkyl, or NR42R43 represents pyrrolidinyl, or R4 represents lower alkyl; R5 is selected from group, heteroaryl, consisting of and , said aryl and heteroaryl being optionally substituted in one or more positions with one or more substituents, independently selected from group consisting of H, halogen, lower alkyl and (CH2)VR53, where R51 is selected from group consisting of H, lower alkyl, lower alkenyl and lower alkylaryl, said lower alkylaryl is optionally substituted in one or more positions with one or more lower alkyl, -CN, halogen, group -COOR54 and group -CH2OR54, where R54 represents lower alkyl or H; R52 represents lower alkyl or -H; R53 represents H, lower alkyl, C3-C6-cycloalkyl, -COOR55, -N(R55)(R56), -CH2OH, -CN, CF3, -CONH2 or -CH2OR55, where R55 is independently selected from group consisting of lower alkyl, -H, -C(O)aryl or -C(O)-lower alkyl
