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.
