(+)-Kavain is a primary kavalactone derived from Piper methysticum, known for its anticonvulsive properties. It functions by interacting with voltage-dependent Na+ and Ca2+ channels, thereby attenuating vascular smooth muscle contraction. Additionally, it has been shown to bind to the α4β2δ GABAA receptor, enhancing GABA efficacy. Its anti-inflammatory actions have been extensively researched, making it a subject of study for inflammatory disease treatments.
