Abstract Kynurenate produces an unsurmountable antagonism of the response to N-methyl-D-aspartate (NMDA) in the baby rat hemisected spinal cord. This effect is completely reversible and prevented by co-superfusion with D-serine or glycine in the presence of strychnine. In the presence of D-serine kynurenate acts as a weak competitive antagonist. The results suggest that one of the actions of kynurenate is to antagonise NMDA responses via an action at the strychnine-insensitive glycine receptor.
