Research Abstract

Effects of isoquinoline alkaloids isolated from Coptis Rhizoma were examined on activity of Transient receptor potential（TRP）channel, which has multiple physiological functions in biological organs. Furthermore, stimulatory effects of various drugs including auranofin and some NADPH oxidase inhibitors on TRP ankyrin1（TRPA1） channel were identified.
