hMAO-B-IN-11 (Compound 12) is a selective and reversible inhibitor of human monoamine oxidase B (hMAO-B) with an IC50 of 0.11 µM. hMAO-B-IN-11 acts through competitive binding to the hMAO-B active site, preventing oxidative deamination of monoamines and reducing hydrogen peroxide production. hMAO-B-IN-11 also inhibits pro-inflammatory mediators (NO, TNF-alpha, IL-1beta) in activated microglia, hMAO-B-IN-11 is promising for research of neurodegenerative diseases like Parkinsons and Alzheimers[1].
