Summary of the inhibitory effects of camphor analogs on the activity of human transient receptor potential channel TRPA1 (hTRPA1) activity. Fura-2 ratios (340/380 nm) by test compounds (1 mM) were normalized to changes in the fura-2 ratio by 1 mM menthol in human embryonic kidney (HEK) 293T cells expressing hTRPA1. Data are presented as the mean ± standard error of the mean (SEM) (n = 27–67)
