FIELD: organic chemistry, pharmacy.
SUBSTANCE: invention relates to novel derivatives of bipiperidine of the formula (I): 
, wherein X means a direct bond, -CH2-, -CH2-CH2- or -CHR9-; R1 means optionally R10- and/or R11-substituted phenyl, optionally R10- and/or R11-substituted heteroaryl, N-oxide of optionally R10- and/or R11-substituted heteroaryl or optionally R10- and/or R11-substituted naphthyl; R2 has one of values given for R1, or it means optionally R10-substituted (C1-C6)-alkyl, optionally R10-substituted (C3-C6)-cycloalkyl, optionally R10-substituted adamantyl; R3 has one of values given for R1; each radical among R4, R5, R6 and R7 means hydrogen atom; R8 means hydrogen atom or (C1-C6)-alkyl; R9 means (C1-C6)-alkyl or (C3-C6)-cycloalkyl; R10 represents from 1 to 4 substitutes chosen independently from (C1-C6)-alkyl, (C1-C6)-hydroxyalkyl, (C2-C6)-alkoxyalkyl, (C1-C6)-halidealkyl, (C3-C6)-cycloalkyl, phenyl, heteroaryl, heteroaryl N-oxide, fluorine, chlorine, bromine, iodine atoms, hydroxyl, groups -OR9, -CONH2, -CONHR9, -CONR9R9, -COOH, -CF3, -CHF2, -CN, -NH2, -NHR9, -NHC(O)R9, -NR9C(O)R9; R11 represents two adjacent substitutes that form anellated 4-7-membered nonaromatic ring optionally comprising up to two heteroatoms chosen independently from nitrogen oxygen and sulfur atoms; Y means a direct bond, -C(O)-, -S(O2)-, -CH2-. Proposed compounds can be in free form as a salt. Compounds of the formula (I) and their salts possess antagonistic activity with respect to CCR5-receptors and can be used in medicine.
EFFECT: valuable medicinal properties of compounds and pharmaceutical composition.
