Dauricine is a plant metabolite, chemically classified as a phenol, an aromatic ether, and an isoquinoline alkaloid.

[1] It has been isolated from the Asian vine Menispermum dauricum, commonly known as Asian moonseed, and the North American vine Menispermum canadense, commonly known as Canadian moonseed.

[2] Scientists Tetsuji Kametani and Keiichiro Fukumoto of Japan are credited with being the first to synthesize dauricine in 1964, using both the Arndt-Eistert reaction and Bischler-Napieralski reaction to do so.

[3] Dauricine has been studied in vitro for its potential to inhibit cancer cell growth[4][5][6][7] and to block cardiac transmembrane Na+, K+, and Ca2+ ion currents.
