NS 383

Key Product Details

Product Description

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; IC_5O 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.
