ABSTRACT A cycloalkylurea compound of the formula (I): Image (I) wherein Rl is a group of the formula (a): Image (a) (wherein R6, R7 and R8 are the same or different and each is hydrogen or alkyl having 1 to 8 carbon atoms, with the proviso that compounds wherein two or three of R6, R7 and R8 are hydrogens are excluded), haloalkyl, cycloalkyl, alkoxy having 1 to 5 carbon atoms, phenyl, aralkyl or heteroaryl, or phenyl, aralkyl or heteroaryl each substituted on the aromatic ring by 1 to 3 substituents selected from alkyl having 1 to 4 carbon atoms, alkoxy having 1 to 8 carbon atoms, cycloalkyl, cycloalkyloxy, haloalkyl, haloalkoxyl halogen, nitro, amino and substituted amino; R2 is hydrogen, phenyl or phenyl substituted by 1 to 3 substi- tuents selected from alkyl having 1 to 4 carbon atoms, alkoxy having 1 to 4 carbon atoms, haloalkyl and halogen, whererin R1 and R2 may be substituted on the same carbon atom of cycloalkyl ring; R1 and R2 together may form a substituted or unsubstituted cyclic hydrocarbon having 3 to 7 carbon atoms or a substituted or unsubstituted spiran; R3 is hydrogen, alkyl having 1 to 8 carbon atoms, cycloalkyl, cycloalkylalkyl, alkoxyalkyl, alkylthioalkyl, aralkyl substituted by alkylenedioxy, aralkyl, aralkyloxyalkyl, aralkyl or aralkyloxyalkyl each substituted on the aromatic ring by 1 to 3 substituents selected from alkyl having 1 to 4 carbon atoms, alkoxy having 1 to 5 carbon atoms, halogen, nitro, hydroxy, amino, substituted amino, haloalkyl, alkylthio, benzyloxy and benzylthio, heteroarylalkyl, phenoxyalkyl, or heteroarylalkyl or phenoxyalkyl each substituted on the aromatic ring by 1 to 3 substituents selected from halogen, alkyl having 1 to 4 carbon atoms, alkoxy having 1 to 4 carbon atoms, nitro, amino and haloalkyl, or a group of the formula (c) or (d): Image (c) Image (d) wherein m is 1 or 2, R11 is hydrogen or alkyl having 1 to 4 carbon atoms, R12 is hydrogen, alkyl having 1 to 4 carbon atoms or aralkyl; R4 is phenyl substituted by 1 to 3 substituents selected from alkyl having 1 to 4 carbon atoms, alkoxy having 1 to 4 carbon atoms, haloalkyl, halogen, amino and substituted amino; n is 1, 2 or 3; or a pharmaceutically acceptable salt thereof, which compound inhibits ACAT and is useful as hypolipidemic and anti- atherosclerotic medicine.
