DL-AP5 Sodium salt
Biological Activity for DL-AP5 Sodium salt
DL-AP5 Sodium salt is the sodium salt of DL-AP5 (Cat. No. 0105) and a racemic mixture of the D- and L-isomers of AP5, a selective NMDA receptor antagonist that competes with glutamate binding and is commonly used to inhibit NMDA-dependent synaptic plasticity. D-AP5 (Cat. No. 0106) is the more active isomer and displays approximately 52-fold higher potency than the L-isomer, L-AP5 (Cat. No. 0107). In vitro D-AP5 reduces NMDA-induced depolarization of cortical neurons, with no effect on the response to L-Quisqualic acid (Cat. No. 0188) or Kainic acid (Cat. No. 0222). Following spinal injection of D-AP5, NMDA-response is rapidly reduced, with no effect seen on spontaneously active neurons.

Alzheimer's disease (AD) is a degenerative brain disease and the most common cause of dementia, affecting approximately 47 million people worldwide. Updated in 2015, this poster summarizes the structural and functional changes observed in the progression of this neurodegenerative disease, as well as classic AD drug targets.
Major depressive disorder is characterized by depressed mood and a loss of interest and/or pleasure. Updated in 2015 this poster highlights presynaptic and postsynaptic targets for the potential treatment of major depressive disorder, as well as outlining the pharmacology of currently approved antidepressant drugs.
Epilepsy is a brain disease that affects 60 million people globally. More than 20 anti-seizure drugs are currently available, but these do not address the underlying causes of the condition. This poster summarizes current knowledge about the development of the condition and highlights some approaches that have disease-modifying effects in proof-of-concept studies.
Huntington's Disease Poster
Huntington's disease (HD) is a monogenic neurodegenerative disorder, which is characterized by the prevalent loss of GABAergic medium spiny neurons (MSN) in the striatum. This poster summarizes the MSN intracellular signaling pathways implicated in the pathology of HD, as well as highlighting the use of iPSCs for HD modeling.
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.
Peripheral sensitization is the reduction in the threshold of excitability of sensory neurons that results in an augmented response to a given external stimulus. This poster outlines the excitatory and inhibitory signaling pathways involved in modulation of peripheral sensitization. The role of ion channels, GPCRs, neurotrophins, and cytokines in sensory neurons are also described.
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.
