Disclosed are a phenol compound represented by the formula (1):
wherein R0 represents H, alkyl or alkyloxy; R1 represents alkyl; R2 represents alkyl or alkyloxy; OR3 represents OH; R4 represents H, lower alkyl or acyl, each of the above substituents may be substituted; W represents O, S or NR7; where R7 represents H, alkyl, aryl, OH or alkyloxy; a group of the formula (2):
represents an amino which may be mono- or di-substituted or heterocyclic group containing N atom,
or a pharmaceutically acceptable salt thereof, and a process for preparing the same.
The compounds of formula (1) possess both an ACAT inhibitory activity and an antioxidative activity.
hydroxyphenylurea derivatives were synthesized and their inhibitory potency evaluated against acyl-CoA: cholesterolacyltransferase (ACAT). Quantitative structure activity relationship analysis revealed that their ACAT inhibitory activities were controlled by the hydrophobicity of the whole molecule. the substitution pattern of urea moiety, and the existence of carboxylic acid. The derivatives with strong
