Gambierol adalah toksin eter polisiklik laut yang diproduksi oleh dinoflagellata Gambierdiscus toxicus.[2] Gambierol dikumpulkan dari laut di Semenanjung Rangiroa di Polinesia Prancis. Toksin dapat terakumulasi dalam ikan melalui rantai makanan dan karena itu dapat menyebabkan keracunan pada manusia. Gejala toksisitasnya mirip dengan ciguatoksin, yang merupakan neurotoksin yang sangat kuat yang mengikat saluran natrium yang peka terhadap tegangan listrik dan mengubah fungsinya. Ciguatoksin ini adalah penyebab keracunan daging ikan ciguatera. Karena kemiripannya, ada kemungkinan gambierol juga bertanggung jawab atas keracunan ikan ciguatera. Karena sumber alami gambierol terbatas, studi biologi terhambat. Oleh karena itu, diperlukan sintesis kimia.[3]
