title: Inhibition of lipid peroxidation in spinal cord homogenates by various drugs.
abstract: The extent and kinetic profiles of lipid peroxidation induced with Fe2+-ascorbic acid in a homogenate of spinal cord from greyhound dogs were ascertained by measurement of the formation of malondialdehyde (MDA) and chemiluminescence in the presence of four drugs. Changes in MDA and chemiluminescence were correlated as a function of the activator or inhibitors. The kinetic profiles of chemiluminescence which were observed for 25 min after addition of the activator and individual inhibitors were similar regardless of the type of inhibitor studied. The most effective inhibition was by disulfiram which was approximately 11 and 33 times more effective than two other inhibitors, propyl gallate and promethazine, respectively, and 11,000 times more effective than D-alpha-tocopherol.
