Application

4-Amino-3-nitrophenol was used in the synthesis of benzimidazole based Factor Xa (trypsin-like serine protease) inhibitors[1] and 4-(4-amino-3-nitrophenoxy)phthalonitrile[2]. It was also employed as matrix during visible matrix-assisted laser desorption/ionization mass spectrometry[3].

Inhibitors based on the benzimidazole scaffold showed subnanomolar potency against Factor Xa with 500-1000-fold selectivity against thrombin and 50-100-fold selectivity against trypsin. The 2-substituent on the benzimidazole ring had a strong impact on the FXa inhibitory activity. Crystallography studies suggest
