KV11.1 (hERG) and KV4.3 channel activator. Activates the IKr and Ito currents and displays antiarrhythmic activity. May also act as a partial blocker of KV11.1 channels. Displays selectivity over the key cardiac potassium channels, KV7.1 (KCNQ1) and KV1.5. Suitable for both in vitro and in vivo use.

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.
