Biological Activity for ATPA

ATPA is a selective and potent GluK1 (formerly GluR5) kainate receptor agonist (K_i = 4.3 nM), inactive at GluK6 (formerly GluR6) (K_i > 1 mM) and only weakly active at AMPA receptors (GluA1-4) and the kainate receptors GluK5 (formerly KA-2) and GluK3 (formerly GluR7) (K_i values of 6 - 14 μM).

Please refer to IUPHAR Guide to Pharmacology for the most recent naming conventions.
