Potent group II/III mGlu receptor antagonist, with approximately 20-fold selectivity for group III over group II (IC50 values of 2.2 and 46.2 nM respectively). A much less potent antagonist at group I receptors in neonatal rat cortical slices (KB = 0.65 ± 0.07 nM). Also available as part of the Group III mGlu Receptor Tocriset™.

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
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.
Parkinson's disease (PD) causes chronic disability and is the second most common neurodegenerative condition. This poster outlines the neurobiology of the disease, as well as highlighting current therapeutic treatments for symptomatic PD, and emerging therapeutic strategies to delay PD onset and progression.
