Ikoamide, an Antimalarial Lipopeptide from an Okeania sp. Marine Cyanobacterium
摘要:
An antimalarial lipopeptide, ikoamide, was isolated from an Okeania sp. marine cyanobacterium. Its gross structure was established by spectroscopic analyses, and the absolute configuration was clarified based on a combination of chiral phase HPLC analyses, spectroscopic analyses, and derivatization reactions. Ikoamide showed strong antimalarial activity with an IC50 value of 0.14 mu M without cytotoxicity against human cancer cell lines at 10 mu M.
