A new cytostatic depsipeptide, designated "dolastatin 14", was isolated from the Indian Ocean shell-less mollusk Dolabella auricularia. Dolastatin 14 inhibited growth of the PS leukemia with ED₅₀ 0.0018 g/mL. Pharmaceutical preparations and therapeutic regimens utilizing Dolastatin 14, its synthetic counterpart and pharmaceutically active derivatives are disclosed. Dolastatin 14 has the structural formula:
从印度洋无壳软体动物 Dolabella auricularia 中分离出一种新的细胞抑制性去肽,命名为 "dolastatin 14"。多拉斯汀 14 能抑制 PS 白血病的生长,ED₅₀ 0.0018 克/毫升。本研究公开了利用多拉他汀 14、其合成对应物和药用活性衍生物的药物制剂和治疗方案。多拉他汀 14 的结构式为
