Effects of borneol, 2-methylisoborneol, and fenchyl alcohol on menthol- and flufenamic acid (FFA)-induced hTRPA1 currents in HEK293T cells. a–c Representative menthol (1 mM)-induced hTRPA1 current that was inhibited by borneol (1 mM, a), 2-methylisoborneol (1 mM, b), or fenchyl alcohol (1 mM, c) in the absence of extracellular Ca2+. d–f Representative FFA (100 μM)-induced hTRPA1 current that was inhibited by borneol (1 mM, d), 2-methylisoborneol (1 mM, e), or fenchyl alcohol (1 mM, f) in the absence of extracellular Ca2+
