An exclusive club: The first member of an unprecedented class of polyunsaturated and polyhydroxylated macrocycle, belizeanolide (see structure), has been isolated from a marine dinoflagellate. The corresponding open form, belizeanolic acid, was also found. Their structures were determined primarily by analysis of NMR spectroscopic data. Both compounds showed significant antiproliferative activities.
