In the search for new potential hypolipidemic agents, the present study focused on the synthesis of 2-acyl phenols (6a-c and 7a-c) and their saturated side-chain alkyl phenols (4a-c and 5a-c), and on the evaluation of their hypolipidemic activity using a murine Tyloxapol-induced hyperlipidemic protocol. The whole series of compounds 4-7 greatly and significantly reduced elevated serum levels of total cholesterol, LDL-cholesterol, and triglycerides, with series 6 and 7 showing the greatest potency ever found in our laboratory. At the minimum dose (25mg/kg/day), the latter compounds lowered cholesterol by 68-81%, LDL by 72-86%, and triglycerides by 59-80%. This represents a comparable performance than that shown by simvastatin. Experimental evidence and docking studies suggest that the activity of these derivatives is associated with the inhibition of HMG-CoA reductase.
