This invention relates to 2-ureido-benzamide compounds of the formula :
in which R1 is H, halogen atom, (C1-C4)alkyl, (C1-C4)alkoxy or (C1-C4)dialkylamino and R2 is H, halogen atom, hydroxy, nitro, (C1-C4)alkyl, (C1-C4)alkoxy or -(CH2)jNR3R3, wherein j is an integer of from 0 to 2, R3 and R4 are each independently H, (C1-C4)alkyl, (C1-C4)alkylsulfonyl or (C1-C4)alkylcarbamoyl, or R3 and R4 taken together with the N-atom to which they are linked can form a pyrrolidine, piperidine, morpholine, imidazole or pyrazole ring ;
X is a (C3-C15)alkyl or -(CH2)kNR5R6 group, wherein k is an integer of from 1 to 4 and R5 and R6 are each independently H, (C1-C6)alkyl or (C1-C4)alkoxycarbonyl ; and,
Y is H or (C1-C4)alkyl and Z is
or -(CH2)m―A2
wherein m is an integer of from 0 to 4, Q is -CH2- or -CH2CH2-, A1 is phenyl, benzyl, diphenylmethyl, pyridyl, imidazolyl, imidazolythio, dibenzoxepinyl or phenoxycarbonyl optionally carrying halogen atom, hydroxy, (C1-C7)alkyl, (C1-C4)alkoxy, (C1-C4)alkoxymethyl, phenyl or halogenophenyl, A2 is phenyl, benzyl, diphenylmethyl, imidazolylthio, dibenzoxepinyl or phenoxycarbonyl optionally carrying halogen atom, hydroxy, (C1-C7)alkyl, (C1-C4)alkoxy, (C1-C4)alkoxymethyl, phenyl or halogenophenyl, R7 is H or (C1-C4)alkyl and R8 is (C1-C4)alkyl, or R7 and R8 taken together with the C-atom to which they are linked can form a cyclopentyl, cyclohexyl or cycloheptyl ring ; or,
Y and Z taken together with the N-atom to which they are linked can form a ring
wherein n is an integer of from 1 to 3 and B is phenyl, diphenylmethyl or dibenzocycloheptenyl optionally carrying halogen atom or (C1-C4)alkoxy ; and pharmaceutically acceptable acid addition salts thereof.
Those compounds are useful as acyl-CoA:cholesterol acyltransferase inhibitors.
