General description

Methyl indole-3-carboxylate (3-Methoxycarbonylindole, 3-Carbomethoxyindole, Methyl indolyl-3-carboxylate) has been extracted from the marine Streptomyces sp. 060524. Its crystal structure indicates the presence of inter­molecular N-H…O hydrogen bond. It is also obtained during the isolation of sorazinones A and B from Sorangium cellulosum strain Soce895. It undergoes regioselective dibromination with bromine in acetic acid to afford methyl 5,6-dibromoindole-3-carboxylate.


Reactant for preparation of:
  • Nitric oxide synthase (nNOS) inhibitorS
  • Protein kinase c alpha (PKCα) inhibitors
  • Inhibitors of the C-terminal domain of RNA polymerase II as antitumor agents
  • Kinase insert domain receptor (KDR) inhibitors
  • Organocatalysts for the anti-Mannich reaction
  • Very late antigen-4 (VLA-4) antagonists
  • Inhibitors of Human 5-Lipoxygenase
  • Serotonin 5-HT4 receptor antagonists
  • Hyaluronidase inhibitors

Reactant for:
  • Enantioselective Meerwein-Eschenmoser Claisen rearrangement reactions†

Treatment of methyl indole-3-carboxylate with bromine in acetic acid gives methyl 5,6-dibromoindole-3-carboxylate regioselectively, from which the parent 5,6-dibromoindole can be accessed via a one-pot, microwave-mediated ester hydrolysis and decarboxylation. Application of these building blocks in syntheses of natural and non-natural

Broccoli (Brassica oleracea L. var. italica) sprouts contain glucosinolates (GLs) that when hydrolysed yield health promoting isothiocyanates such as sulforaphane (SF). SF content can be increased by salt (NaCl) stress, although high salt concentrations negatively impact plant growth. Salicylic acid
