Description and Uses

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.
