Pyrrolylquinoxalinediones carrying a piperazine residue represent highly potent and selective ligands to the homomeric kainate receptor GluR5.
Pyrrolylquinoxalinediones carrying aminoalkyl residues were evaluated for affinity to the recombinant, homomeric kainate receptors GluR5, GluR6 and GluR7. Most derivatives preferred binding to GluR5. In particular, the piperazine 6e represents a highly potent and selective antagonist to GluR5.
