The absolute stereostructure of arenastatin A (1), which was isolated from the Okinawan marine sponge Dysidea arenaria, has been determined on the bases of NMR and synthetic studies. Arenastatin A (1) is a cyclic depsipeptide exhibiting extremely potent cytotoxicity against KB cells with IC50 5pg/ml.
根据核磁共振和合成研究,确定了从冲绳海洋海绵 Dysidea arenaria 中分离出来的阿那曲汀 A (1) 的绝对立体结构。阿仑他汀 A (1) 是一种环状去肽类化合物,对 KB 细胞具有极强的细胞毒性,IC50 为 5pg/ml 。
