NS 383 is an ASIC blocker (IC50 values are 0.44, 2.1 μM and no effect at rat ASIC1a, ASIC3 and ASIC2a, respectively: IC50 value = 0.12 μM at human ASIC1a with no effect at ASIC2a or ASIC3). Inhibition was also observed at heteromeric ASIC channels (IC50 values are 0.79, 0.87 and 4.5 uM at rat ASIC1a+3, ASIC1a+2a and ASIC2a+3; IC5O values are 0.33 and 0.69 uM at human ASIC1a+2a and ASIC1a+3, with no effect at ASIC2a+3). Attenuates pathophysiological nociceptive behaviors in CFA-inflamed and CCI rats.

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.
