Abstract: FIELD: chemistry. ^ SUBSTANCE: invention relates to novel imidazole derivatives of general formula I and pharmaceutically acceptable salts thereof, where R1 is selected from a group comprising aryl and alkyl, optionally substituted hydroxy; R2 is selected from a group comprising hydrogen and alkyl; R3 is selected from a group comprising hydrogen and -X-A, where X is selected from a group comprising -C(O)- and -S(O)2-; and A is selected from a group comprising hydrogen, optionally substituted alkyl, optionally substituted alkoxy, optionally substituted aryl, optionally substituted heteroaryl, optionally substituted heterocycle and optionally substituted cycloalkyl, where the optionally substituted groups are substituted with 1-2 substitutes selected from a group comprising alkyl, substituted alkyl, alkoxy, substituted amine which is a -NRR group, substituted aryloxy, heteroaryl, heterocycle, halogen, hydroxy and -S(O)2-R9, where R9 is an alkyl; or R1 and R3 together with a carbon atom bonded to R1 and a nitrogen atom bonded to R3 form a heterocyclic or substituted heterocyclic group; R4 is selected from a group comprising hydrogen, linear alkyl, -alkylene-aminoacyl-, -alkylene-hydroxy-, -[alkylene]p-nitrogen-containing heterocycle, -[alkylene]p-nitrogen-containing substituted heterocycle, -[alkylene]p-nitrogen-containing heteroaryl, -[alkylene]p-nitrogen-containing substituted heteroaryl and -[alkylene]p-NR10R11, where p equals 0 or 1, the alkylene contains 1-5 carbon atoms and can have 1 or 2 substitutes selected from a group comprising amine, hydroxy and halogen, aminoacyl relates to a group -C(O)NRR, where each R is independently selected from a group comprising hydrogen and alkyl, R10 and R11 are independently selected from a group comprising hydrogen, alkyl, substituted alkyl, -S(O)2-alkyl, substituted aryl, substituted heteroaryl, cycloalkyl, or when R10 is hydrogen, R11 is hydroxy, alkoxy or substituted alkoxy; or when R1 and R3 together with carbon and nitrogen atoms respectively bonded to them do not form a heterocyclic or a substituted heterocyclic group, R3 and R4 together with a nitrogen atom to which they are bonded form a spiro-condensed heterocyclic group; R5 is selected from a group comprising L-A1, where L is selected from a group comprising C1-C5alkylene, where the alkylene is defined above; and A1 is selected from a group comprising aryl, substituted aryl, heteroaryl, substituted heteroaryl, heterocycle; and one of R6 or R7 is selected from a group comprising aryl and heteroaryl, each of which can optionally be substituted with -(R8)m, where m equals a whole number from 1 to 2, and the other of R6 or R7 is selected from a group comprising hydrogen, halogen and alkyl; or R6 as well as R7 denotes hydrogen; R8 is selected from a group comprising cyano, alkyl, -CF3, alkoxy, halogen, where alkyl, aryl, aryloxy, cycloalkyl, heterocycle, heteraryl and substituted alkyl, aryl, aryloxy, cycloalkyl, heterocycle and heteroaryl are described in claim 1. The invention also relates to specific compounds, a pharmaceutical composition based on the compound of formula I, a method of inhibiting KSP and use of the composition to prepare a medicinal agent. ^ EFFECT: novel imidazole derivatives are useful as kinesin spindle protein inhibitors for treating cancer. ^ 25 cl, 27 ex
