Heme Oxygenase-1-IN-2 is a novel inhibitor of heme oxygenase-1 (HO-1), displaying potent antiproliferative activity in vitro, with an IC50 value of 0.95 μM.
9-cis-β-Carotene, a precursor of retinal, is cleaved by beta-carotene oxygenase 1 (BCMO1) to produce 9-cis-retinal. It inhibits photoreceptor degeneration and restores retinal function in vivo.
