Utreloxastat (PTC857) is an orally active 15-lipoxygenase inhibitor that can cross the blood-brain barrier. Utreloxastat is a weak inhibitor of CYP1A2 and 2B6 with an IC50 > 5.3 μM. Utreloxastat reduces oxidative stress and inhibits the consumption of reduced glutathione and ferroptosis. Utreloxastat can be used in the study of neurodegenerative diseases characterized by high levels of oxidative stress and mitochondrial pathology, such as amyotrophic lateral sclerosisc[1][2].
