Orally active, subtype-selective partial agonist at α4β2 nicotinic receptors (Ki values are 0.06, 240, 322 and 3540 nM for α4β2, α3β4, α7, α1βγδ receptors respectively). Reduces nicotine-evoked dopamine release in vitro and decreases nicotine self-administration in vivo. Also potently activates PSAM4-5-HT3 and PSAM4-GlyR chimeric ion channels (EC50 values are 4 and 1.6 nM, respectively)
Sold for research purposes under agreement from Pfizer Inc.

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.
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.
