4184 Gambieric acid B 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 (A3251). 141363-65-7 46173843 C60H94O16 White powder.
