Biological Activity

Potent IKs blocker (IC50 = 64 nM). Displays no effects on other cardiac channels; IC50 values are 3.3, >10, 11.1 and 12.6 μM for INa, ICa, Ito and IKr currents respectively. Prolongs QT and causes unprovoked torsades de pointes (TdP).

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.
