Biological Activity

Selective KV7.2/KV7.3 (KCNQ2/3) channel opener (EC50 = 0.69 μM). Exhibits 20-fold selectivity for KV7.2/KV7.3 over KV7.3/KV7.5, with no measurable activity over a panel of cardiac ion channels. Hyperpolarizes resting membrane potential and inhibits spontaneous action potentials in guinea pig detrusor muscle (DSM) isolated cells. Orally active in animal models of epilepsy.

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.
