Studies on the relationship between the structure of the benzene moiety of S-(2-(acylamino) phenyl) 2, 2-dimethylpropanethioates and CETP inhibitory activity were performed. Substituents on the benzene moiety influenced CETP inhibitory activity in a type and position dependent manner, and electron-withdrawing groups at the 4-or 5-position increased the activity. The most potent compound showed 50% inhibition of CETP activity ...
