title: Antioxidant effect of calmodulin antagonists in rat brain homogenate.
abstract: Several calmodulin antagonists, W-7, amitriptyline, trifluoperazine, chlorpromazine, dibucaine, prenylamine, calmidazolium, and compound 48/80, inhibited lipid peroxidation induced non-enzymatically in rat brain homogenate by ascorbate and Fe2+. Suggestions of involvement of calmodulin in various oxidative cellular responses, based on experiments using calmodulin antagonists, may need to be re-evaluated.
