Structure and activity of largazole, a potent antiproliferative agent from the Floridian marine cyanobacterium Symploca sp.
A novel cytotoxic cyclodepsipeptide, termed largazole (1), has been isolated from the marine cyanobacterium Symploca sp. collected in the Florida Keys. Its planar structure was elucidated by 1D andExpand
