Description
Polygodial (6754-20-7) is a TRPA1 activator (EC50=400 nM).1?A naturally occurring drimane sesquiterpene dialdehyde found in a variety of plant species including water pepper (Polygonum hydropiper). Polygodial has been used in folk medicine for a variety of indications. Displays analgesic activity via desensitization of sensory neurons.2
Uses
Polygodial is a naturally occurring antifungal and antinociceptive.
Definition
ChEBI: Polygodial is an aldehyde.
Biochem/physiol Actions
Polygodial is a selective activator of Transient Receptor Potential Anykrin 1 (TRPA1) channels. Initially painful, polygodial acts as an analgesic by desensitizing sensory neuron. Polygodial also has broad antifungal properties, and is cytotoxic against bacteria and algae.
