Overview
Isatin is an endogenous monoamine oxidase (MAO) inhibitor involved in stress and anxiety. Additionally, isatin inhibits alkaline phosphatase (ALP), nitric oxide (NO)-stimulated soluble guanylate cyclase, and other enzymes. An endogenous monoamine oxidase inhibitor.
Application:
Isatin can be used as a reactant to prepare: Phthalazinone derivatives. Spirooxindole derivatives. Agents against multidrug-resistant cells expressing P-glycoprotein. Thiazolidinones spiro-fused to indolin-2-ones as potent and selective inhibitors of Mycobacterium tuberculosis protein tyrosine phosphatase B. Triazole-isatine compounds as potential antibacterial and antifungal agents. Biologically relevant scaffolds such as spiro[indole-thiazolidinones]. It can be a reactant for: Cascade reactions with heterocyclic ketene aminals. Knoevenagel condensation reactions. Isatin can also be used as a chromatographic spray reagent for amino acids, and also as a reference material in the preparation of indigo and Maya Blue. It is responsible for the yellow color exhibited by the "Maya Yellow" pigment. Isatin undergoes Pd(II)-catalyzed C-H addition by direct sp2/sp3 C-H bond activation to form 3-substituted-3-hydroxy-2-oxindoles. Isatin derivatives (bis-Schiff base) are synthesized by the condensation of the natural or synthetic isatins with hydrazine.
Selective endogenous MAOB inhibitor and potent ANP receptor antagonist (IC 50 = 3-8 and 0.4 μM respectively). Inhibits alkaline phosphatase and (NO-stimulated soluble guanylate cyclase. Anxiolytic, sedative, anticonvulsant and antidiuretic effects in vivo

Note
Wherever possible, you should prepare and use solutions on the same day. However, if you need to make up stock solutions in advance, we recommend that you store the solution as aliquots in tightly sealed vials at -20°C. Generally, these will be useable for up to one month. Before use, and prior to opening the vial we recommend that you allow your product to equilibrate to room temperature for at least 1 hour.

This compound belongs to the class of organic compounds known as indolines. These are compounds containing an indole moiety, which consists of pyrrolidine ring fused to benzene to form 2,3-dihydroindole.
