使用Isatin is an endogenous monoamine oxidize (MAO) inhibitor involved in stress and anxiety. Additionally, isatin inhibits alkaline phosphatase (ALP), nitric oxide (NO)-stimulated soluble guanylate cyclase, and other enzymes. Isatins undergo a one-pot Wolff-Kishner like reduction with hydrazine hydrate, under surprisingly mild conditions, to give the corresponding oxindoles. It is used as chromatographic spray reagent for amino acid detection.
純化方法Crystallise isatin from amyl alcohol and sublime it at 180o/1mm. In aqueous NaOH the ring opens to yield sodium o-aminobenzoylformate. [Beilstein 21 II 327, 567, 21 III/IV 4981, 21/10 V 221.]
定義ChEBI: An indoledione that is the 2,3-diketo derivative of indole.
