In vitro activity: Optovin activates human TRPA1 via structure dependent photochemical reactions.

Kinase Assay: Optovin is a reversible photoactivated TRPA1 activator. It activates human TRPA1 via structure dependent photochemical reactions. In dorsal root ganglia (DRG) sensory neurons isolated from mice, optovin significantly activated 33% (35/105) of DRG neurons, which was not occured in the dark. In HEK293T cells transfected with the human TRPA1, optovin activated cells. Optovin activated TRPA1 channels through a photoactivated intermediate that reacted with redox-sensitive cysteine residues in the channel.
