Biological Activity

Neuronal nicotinic receptor antagonist that displays selectivity for the α9α10 subtype (IC50 values are 19, 140, 980, 4200 and 7300 nM for α9α10, α6/α3β2β3, α6/α3β4, α3β4 and α3β2 subtypes respectively). Alleviates neuropathic pain in three rat models of human neuropathic pain and accelerates functional recovery of injured neurons.

Pain Poster

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.
