Ageliferin

Ageliferin is a chemical compound produced by some sponges. It was first isolated from Caribbean and then Okinawan marine sponges in the genus Agelas.[1][2][3] It often co-exists with the related compound sceptrin and other similar compounds. It has antibacterial properties and can cause biofilms to dissolve.[4] Total syntheses have been independently accomplished by the research groups of Phil S. Baran at the Scripps Research Institute,[5][6] Chuo Chen at UT Southwestern Medical Center,[7][8] Patrick Harran at UCLA,[9] and Daisuke Urabe at Toyama Prefectural University.[10]
