Replaces Prod. #: ALX-270-265

Lazaroid inhibitor of iron-dependent lipid peroxidation. Antioxidant. Inhibits lipid peroxidation in a variety of experimental systems including cultured brain microvessel endothlial cells, Cu2+ treated monocyclic THP1 cells and LLC-PK1 cell layers where it blocks F2 isoprostane production. Prevented organ damage in intestinal cold storage, preservation and reperfusion injury.
