Biological Activity

Photoswitchable TRPV1 channel blocker (IC50 = 3.1 μM). Acts as an antagonist in trans conformation during voltage gated activation. Also acts as an antagonist in the cis formation during capsaicin-induced TRPV1 currents. Switches conformation from cis to trans at 440 nm and trans to cis at 360 nm. Allows photoswitchable antagonist and an agonist to be applied at the same time.
