The molecule is a pyranone diterpenoid isolated from Nalanthamala and Chaunopycnis alba and has been shown to be a blocker of the voltage-gated potassium channel Kv1.3 It has a role as a metabolite and a potassium channel blocker. It is a diterpenoid, an enol ether, an ortho-fused bicyclic hydrocarbon, an acetate ester, a member of 4-pyranones and a ketene acetal.
