Potent KV1.3 channel blocker (EC50 = 3 nM). Preferentially binds the C-type inactivated state of the channel, similar to the activity of CP 339818 (Cat. No. 1399). Displays 17- to 70-fold selectivity over closely-related KV1 channels (KV1, KV2, KV4 and KV7); exhibits activity at KV1.5 (IC50 = 7.7 nM). Suppresses proliferation of human and rat myelin-specific effector memory T cells (EC50 values are 25 and 60 nM respectively).

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.
