It is a sodium channel blocker that is undergoing clinical trials as a prolonged-duration local anesthetic. It has a role as a marine metabolite, a neurotoxin, a toxin, a local anaesthetic, a cyanotoxin, a voltage-gated sodium channel blocker and an anti-inflammatory agent. It is an alkaloid, a carbamate ester, a member of guanidines, a ketone hydrate, a pyrrolopurine, a member of hydroxylamines and a paralytic shellfish toxin. It is functionally related to a saxitoxin."}]
