Gambieric acid B is an antifungal compound isolated from the marine dinoflagellate Gambierdiscus toxicus that produces ciguatoxin precursors and maitotoxin. The skeletal structure of gambieric acids (GAs) consists of a nonacrylic polyether core involuving six-, seven-, and nine- membered cyclic ethers, arranged with an isolated tetrahydrofuran ring (A-ring). GAs share the structural characteristics common to those of polycyclic ether neurotoxins, which are produced by G. toxicus, for example, ciguatoxin, maitotoxin, and gambierol (1).
No indication of carcinogenicity to humans (not listed by IARC).
