2,4-Dichloro-3-nitropyridine is a halogenated pyridinium salt that has been shown to inhibit the influenza virus in vitro. This compound is also reactive with nucleophilic groups such as amines, alcohols, and thiols. 2,4-Dichloro-3-nitropyridine has been used for the synthesis of quinoline derivatives that have potential applications in autoimmune diseases or cancer. 2,4-Dichloro-3-nitropyridine has also been found to be an inhibitor of tumor necrosis factor alpha (TNFα) production by LPS stimulated human monocytes.
2,4-Dichloro-3-nitropyridine is a reactant in the discovery of Imigliptin, a novel selective dipeptidyl peptidase IV (DPP-4) inhibitor used in the treatment of type 2 diabetes.
