N-METHYLISATIN Chemical Properties,Usage,Production

Chemical Properties

ORANGE TO BROWNISH CRYSTALLINE POWDER

Uses

1-Methylisatin is used as a reactant for stereoselective preparation of spirobicyclic and bis-spirotricyclic pyrazolidinones, for regioselective preparation of spirocyclic oxindole-butenolides, for synthesis of spiro-oxindoles, for preparation of unsymmetrical oxindoles, for stereoselective preparation of hydroxyloxindoles via Morita-Baylis-Hillman reaction, for preparation of pyridinecarboxylic acid [(oxo)indolylidene)hydrazide derivatives (Schiff base hydrazides) as antibacterial agents.

Uses

  • Reactant for stereoselective preparation of spirobicyclic and bis-spirotricyclic pyrazolidinones
  • Reactant for regioselective preparation of spirocyclic oxindole-butenolides
  • Reactant for synthesis of spiro-oxindoles
  • Reactant for preparation of unsymmetrical oxindoles
  • Reactant for stereoselective preparation of hydroxyloxindoles via Morita-Baylis-Hillman reaction
  • Reactant for preparation of pyridinecarboxylic acid [(oxo)indolylidene)hydrazide derivatives (Schiff base hydrazides) as antibacterial agents

Synthesis Reference(s)

Journal of Medicinal Chemistry, 47, p. 2089, 2004 DOI: 10.1021/jm030483s

General Description

The interaction between 1-methylisatin and human adult haemoglobin was studied using the circular dichroism (CD) spectroscopic, anisotropy and FTIR investigations.

IC 50

hiCE: 38.2 μM (Ki); hCE1: 5.38 μM (Ki)
