M8 B hydrochloride
Biological Activity
Potent and selective TRPM8 channel blocker. Blocks cold- and icilin-induced TRPM8 activation in vitro (IC50 values are 7.8 and 26.9 nM respectively). Exhibits no effect at other TRP channels (IC50 > 20 μM). Reduces body temperature in vivo.
Compound Libraries

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.
