Biological Activity: | Reversible TRPA1 channel blocker (IC 50 values are 3.1 and 4.5 μ M at human and mouse TRPA1 respectively). Blocks cinnameldehyde-induced but not capsaicin-induced nociception and reverses mechanical hyperalgesia in vivo . Also blocks TRPA1 pore dilation (IC 50 = 10.3 μM for the inhibition of Yo-Pro uptake). |
