DERIVATIVES OF NICOTINIC ACID N-OXIDE, THEIR PREPARATION AND THEIR USE AS INHIBITORS OF ENZYME 3-HYDROXYANTHRANILATE-3,4-DIOXYGENASE

摘要

A derivative of nicotinic acid N-oxide is described having formula (I): that acts as inhibitor of enzyme 3-hydroxyanthranilate-3,4-dioxygenase (3HAO), and is thus able to reduce QUIN biosynthesis in vivo under excitotoxic or pathological conditions, said compound being at the same time also chemically stable towards auto-oxidation.
