Application

  • 2-Methylbenzimidazole is an important pharmacophore widely used in medicinal chemistry for the synthesis of various antibacterial and antifungal agents.
  • It can be used as a key precursor to synthesize substituted benzimidazo[1,2-a]quinolones.
  • It can be used in the synthesis of reversible solid-to-liquid phase transition coordination polymer crystals.
  • 2-Methylbenzimidazole also exhibits corrosion inhibition.

We have recently reported that a series of (E)-8-styrylcaffeines and (E)-2-styrylbenzimidazoles are moderate to very potent competitive inhibitors of monoamine oxidase B (MAO-B). The most potent member of the series was found to be (E)-8-(3-chlorostyryl)caffeine (CSC) with an enzyme-inhibitor dissociation
