Acridinic acid: a new antagonist of amino acid-induced excitations of central neurones.

ABSTRACT

The actions of acridinic acid (2,3-quinoline dicarboxylic acid), a new derivative of quinolinic acid, as an antagonist of amino acid-induced excitations are described. Acridinate, like kynurenate, in the cerebral cortex reduced the effects of all amino acids equally, but in the spinal cord was significantly less active against quisqualate.
