Odoamide is a novel cyclic depsipeptide with highly potent cytotoxic activity isolated from the Okinawan marine cyanobacterium Okeania sp. It contains a 26-membered macrocycle composed of a fatty acid moiety, a peptide segment and isoleucic acid. Four possible stereoisomers of the odoamide polyketide substructure were synthesised using a chiral pool approach. The first total synthesis of odoamide was
Odoamide是一种新型的环状二肽,具有从冲绳海洋蓝藻Okeania sp。中分离出来的高效细胞毒活性。它包含一个由脂肪酸部分,肽段和异油酸组成的26元大环。使用手性池方法合成了odoamide聚酮化合物亚结构的四种可能的立体异构体。也成功地完成了对氨基酰胺的第一个全合成。通过比较其核磁共振波谱与天然产物的核磁共振谱,可以验证合成的乙酰胺的结构。
