5-Hydroxy isatin Chemical Properties, Uses, Production
Uses
5-Hydroxyisatin can be used to synthesize anti-cancer agents[1].
Biological Activity
5-hydroxy Isatin is an inhibitor of monoamine oxidase A (MAO-A; IC50 = 8.4 μM).1 It is selective for MAO-A over MAO-B (IC50 = >100 μM). 5-hydroxy Isatin (50 μM) also inhibits atrial natriuretic peptide-induced activation of particulate guanylyl cyclase in rat brain and heart membranes.2
