Abstract: Various mechanisms for regulated cell death include the formation of oxidative mediators such as lipid peroxides and nitric oxide (NO). In this respect, 15-lipoxygenase-1 (15-LOX-1) is a key enzyme that catalyzes the formation of lipid peroxides. The actions of these peroxides are interconnected with nuclear factor-κB signaling and NO production. Inhibition of 15-LOX-1 holds promise to interfere with regulated cell death in inflammatory conditions. In this study, a novel potent 15-LOX-1 inhibitor, 9c (i472), was developed and structure-activity relationships were explored. In vitro, this inhibitor protected cells from lipopolysaccharide-induced cell death, inhibiting NO formation and lipid peroxidation. Thus, we provide a novel 15-LOX-1 inhibitor that inhibits cellular NO production and lipid peroxidation, which set the stage for further exploration of these mechanisms.
