Biological Activity for ML 252
ML 252 is a potent and selective inhibitor of KV7.2 voltage-gated potassium channels (IC50 = 70 nM), which displays >40-fold selectivity for KV7.2 over KV7.1 channels (IC50 = 2.9 μM for KV7.1). ML 252 is the (S)-enantiomer, and is more potent than the (R)-enantiomer or racemic mixture (IC50 values are 944 and 160 nM, respectively). ML 252 displays selectivity for KV7.2 over a panel of >68 GPCRs, ion channels and transporters; inhibits melatonin MT1 receptor 60% at 10 μM. ML 252 is brain penetrant.

Epilepsy is a brain disease that affects 60 million people globally. More than 20 anti-seizure drugs are currently available, but these do not address the underlying causes of the condition. This poster summarizes current knowledge about the development of the condition and highlights some approaches that have disease-modifying effects in proof-of-concept studies.
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.
