6-Nitroindazole

6-Nitroindazole is a competitive and reversible Monoamine oxidase(MAO)inhibitor. It can inhibit MAO-A and MAO-B (IC50= 2.5 μM). Monoamine oxidase (MAO) B is a mitochondrial enzyme selectively involved in the oxidative activation of 1-methyl-4- phenyl-1,2,3,6-tetrahydropyridine (MPTP) neurotoxin to toxic pyridinium cations producing Parkinsonism in animal models. In addition, it is an nNOS inhibitor, which has neuroprotective effects^[1].

6-Nitroindazole is prepared by (2-methyl-5-nitrophenyl)azo phenyl sulfide and 1,8-diazabicyclo[5.4.0]undec-7-ene in the presence of concentrated  acetonitrile.
