Biological Activity for ATPA

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

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

Addiction Poster

Addiction Poster

The key feature of drug addiction is the inability to stop using a drug despite clear evidence of harm. This poster describes the brain circuits associated with addiction, and provides an overview of the main classes of addictive drugs and the neurotransmitter systems that they target.

Learning & Memory Poster

Learning & Memory Poster

Recognition memory enables us to make judgements about whether or not we have encountered a particular stimulus before. This poster outlines the cellular mechanisms underlying recognition memory and its links to long-term depression, as well as the use of pharmacological intervention to assess the role of neurotransmitters in recognition memory.
