Summary
Droloxifene was found to exhibit a membrane antioxidant ability in that it inhibited Fe(III)-ascorbate dependent lipid peroxidation in rat liver microsomes and ox-brain phospholipid liposomes, which may result from a membrane stabilization that could be associated in cancer cells with decreased plasma membrane fluidity.
