Biological Activity

Selective Kv7.1 (KCNQ1) potassium channel activator (EC50 = 260 nM). Exhibits >100-fold selectivity versus KCNQ2, KCNQ4 and hERG potassium channels. Augments IKs current of cultured human cardiomyocytes and shortens action potential duration.

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.
