Description
AP18 is a selective Transient receptor potential A1(TRPA1) channel blocker which reversibly inhibits TRPA1 with IC50 values of 3.1 and 4.5 µM at human and mouse respectively. It has been used to study TRPA1 signaling in mice and rats as well as in vitro. It blocks the transient receptor potential ankyrin 1 receptors and can reduce chronic pain associated with arthritis. It also blocks cinnamaldehyde-induced nociception in vivo and blocks cold- and mustard oil-induced activation of mouse TRPA1 but not capsaicin-induced activation. It reverses CFA-induced mechanical hyperalgesia in mice
