General description

Indole-3-carboxaldehyde can undergo Schiff bases condensation to form multifunctional silica nano-vehicles and magnetic nanoparticles.

Application

Indole-3-carboxaldehyde was used to prepare analogs of the indole phytoalexin cyclobrassinin with NR1R2 group. It was also used as the starting material for the synthesis of higher order indoles including isoindolo[2,1-a]indoles, aplysinopsins, and 4-substituted-tetrahydrobenz[cd]indoles.
Reactant for preparation of:
  • Analgesic agents
  • Hypoglycemic agents
  • Tryptophan dioxygenase inhibitors pyridyl-ethenyl-indoles as potential anticancer immunomodulators
  • Antibacterial and antifungal agents
  • Antiamoebic and cytotoxic agents
  • Inhibitors of the Dengue virus protease with antiviral activity in cell-culture
  • Curcumin analogues as possible anti-proliferative & anti-inflammatory agents
  • Inhibitors of Bcl-2 family proteins
  • Inhibitors of the C-terminal domain of RNA Polymerase II as antitumor agents
  • Inhibitors of TNF-α and IL-6 with anti-tubercular activity

Chronic inflammation can augment tumor development in various types of cancers, including prostate cancer (PCa). Reduction of inflammation is therefore an important anticancer therapeutic opportunity. Here, we report four anti-proliferative phytocompounds in Wedelia chinensis, an oriental herbal medicine, identified through
