In vitro study | At concentrations up to 50 μM, AP-18 is unable to appreciably block activation of TRPV1, TRPV2, TRPV3, TRPV4, or TRPM8. AP-18 reversibly blocks mouse TRPA1 responses to iodoacetamide (an irreversible cysteine-alkylating agent) in CHO cells assayed by ratiometric Ca 2+ imaging. AP-18 also blocks cold- and mustard-oil-induced activation of mouse TRPA1. AP-18 blocks cinnamaldehyde-induced TRPA1 currents in excised patches from Xenopus oocytes . |
In vivo study | AP18 (1 mM; injected in hindpaw of mice) significantly blocks cinnamaldehdye-induced but not capsaicin-induced nociceptive events, demonstrating efficacy and specificity. |

biological activity | AP-18 is a selective TRPA1 inhibitor that blocks the activation of TRPA1 by 50 μm cinnamaldehyde AP-18, the IC50 values in human and mouse were 3.1 μm and 4.5 μm, respectively. AP-18 reversal of CFA-induced mechanical hyperalgesia in mice. AP-18 attenuated 30 μm AITC-induced Yo-Pro uptake in a concentration-dependent manner with an IC50 of 10.3 μm. |
