2-Aminonicotinic acid 1-oxides are chemically stable inhibitors of quinolinic acid synthesis in the mammalian brain: a step toward new antiexcitotoxic agents.[Pubmed:24274468]
J Med Chem. 2013 Dec 12;56(23):9482-95.
3-Hydroxyanthranilic acid 3,4-dioxygenase (3-HAO) is the enzyme responsible for the production of the neurotoxic tryptophan metabolite quinolinic acid (QUIN). Elevated brain levels of QUIN are observed in several neurodegenerative diseases, but pharmacological investigation on its role in the pathogenesis of these conditions is difficult because only one class of substrate-analogue 3-HAO inhibitors, with poor chemical stability, has been reported so far. Here we describe the design, synthesis, and biological evaluation of a novel class of chemically stable inhibitors based on the 2-Aminonicotinic acid 1-oxide nucleus. After the preliminary in vitro evaluation of newly synthesized compounds using brain tissue homogenate, we selected the most active inhibitor and showed its ability to acutely reduce the production of QUIN in the rat brain in vivo. These findings provide a novel pharmacological tool for the study of the mechanisms underlying the onset and propagation of neurodegenerative diseases.
Chemiluminescence derivatization of methylglyoxal using 2-aminonicotinic acid.[Pubmed:10959598]
Chem Pharm Bull (Tokyo). 2000 Aug;48(8):1236-8.
To develop a sensitive and selective chemiluminometric method for the determination of methylglyoxal, we used 2-Aminonicotinic acid as the chemiluminescence derivatization reagent. 2-Aminonicotinic acid reacts with methylglyoxal in an acidic solution at 37 degrees C for 4 h and gave a chemiluminescence in N,N'-dimethylformamide containing sodium tert-butoxide. The detection limit (blank intensity plus three-times its standard deviation of methylglyoxal) for methylglyoxal is 233 fmol in the reaction mixture.
2-Aminonicotinic acid.[Pubmed:9362553]
Acta Crystallogr C. 1997 Oct 15;53 ( Pt 10):1427-9.
2-Aminonicotinic acid, C6H6N2O2, crystallized in the centrosymmetric space group P2(1)/c in the zwitterionic form. Intermolecular N--H...O hydrogen bonds with N...O distances of 2.652 (2) and 2.807 (2) A link molecules into two sets of zigzag chains propagating along the b axis. The two sets of chains are crosslinked by C--H...O interactions. The dihedral angle between the planes of adjacent molecules in a chain is 9.77 (7) degrees. An intramolecular N--H...O hydrogen bond is also present.
