Biological Activity for AP 18

AP 18 is a reversible TRPA1 channel blocker (IC50 values are 3.1 and 4.5 μM at human and mouse TRPA1 respectively). Blocks cinnamaldehyde-induced but not capsaicin-induced nociception and reverses mechanical hyperalgesia in vivo. Also blocks TRPA1 pore dilation (IC50 = 10.3 μM for the inhibition of Yo-Pro uptake).
