Ikoamide (1) is a highly N-methylated antimalarial lipopeptide that was isolated from a marine cyanobacterium, an Okeania sp. in 2018, which shows strong antimalarial activity without cytotoxicity against human cancer cell lines. To establish a synthetic method for obtaining enough ikoamide for its biological evaluations, we have established a total synthesis of ikoamide. The synthetic method presented here lays the foundation for the development of novel ikoamide analogues, which may lead to a discovery of pharmaceutically unique antimalarial drug leads.
