RO 16-6491 (free base)

RO 16-6491 Free base is a selective, reversible inhibitor of monoamine oxidase type B (MAO-B), exhibiting high affinity and specificity for binding sites in human frontal cortex mitochondria and platelet membranes. RO 16-6491 demonstrates a fast dissociation of bound radioactivity at 20 degrees C, indicating its dynamic binding properties. RO 16-6491 also acts as a substrate for MAO-B, suggesting that its oxidation may produce a stable intermediate responsible for its potent inhibitory effects. RO 16-6491 serves as an excellent radioligand probe for investigating the regional tissue distribution of MAO-B in various physiological and pathological states.
