Because alpha-tocopherol (alpha-TOH) mediates the peroxidation of cholesterol-esterified lipids in human low-density lipoprotein (LDL) in vitro and has displayed disappointing results against the onset and development of atherosclerosis, it may not be appropriate for use as a therapeutic in the prevention and/or treatment of the disease. Herein are described the experimental results demonstrating that 3-pyridinols spare alpha-TOH, do not efficiently mediate lipid peroxidation, and protect lipoprotein tryptophan residues in human LDL.
