Applicazioni

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.

The first Pd(II)-catalyzed C-H addition to isatins by direct sp(2)/sp(3) C-H bond activation for the construction of 3-substituted-3-hydroxy-2-oxindoles is reported. The bidentate nitrogen ligands were found to promote this reaction. Specifically, the preliminary bioassay indicated that 3-(5-chlorobenzoxazole)-3-hydroxy-N-benzyl-2-oxindole (2w) is a

Eighteen symmetrical bis-Schiff base derivatives of isatin were synthesized by condensation of the natural or synthetic isatins with hydrazine and were evaluated for their in vitro and in vivo antitumor activities. More than half of the obtained compounds showed potent
