The present invention is directed to novel kynurenic acid (KYNA) derivatives of the general formula (I) - and pharmaceutically acceptable salts, amides, all possible stereoisomers, including diastereoisomers and/or enantiomers, racemates and mixtures thereof, as well as a process for the preparation thereof, pharmaceutical compositions containing same, and use thereof for the manufacture of pharmaceutical compositions useful in the treatment of headaches, particularly non- neurodegenerative migraine.
The overactivation of excitatory amino acid receptors plays a key role in the pathomechanism of several neurodegenerative disorders and in ischemic and post-ischemic events. Kynurenic acid (KYNA) is an endogenous product of the tryptophan metabolism and, as a broad-spectrum antagonist of excitatory amino acid receptors, may serve as a protective agent in neurological disorders. The use of KYNA is excluded
