A novel norsesterterpene, rhopaloic acid A, was isolated from a marine sponge, Rhopaloeides sp. The structure was determined to be 2-methylene-6-(4,8,12-trimethyl-3,7,11-tridecatrienyl)-3,7-epoxyheptanoic acid on the basis of its spectroscopic data. Rhopaloic acid A inhibited gastrulation of starfish embryos and also exhibited potent cytotoxicities in vitro against human myeloid K-562 cells, human
从海洋海绵Rhopaloeides sp。中分离出了一种新的去甲甾烯萜,Rhopholoic acidA。根据其光谱数据确定该结构为2-亚甲基-6-(4,8,12-三甲基-3,7,11-三癸三烯基)-3,7-环氧庚酸。Rhopaloic acid A抑制海星胚胎的胃形成,并且在体外对人骨髓K-562细胞,人MOLT-4白血病细胞和鼠L1210白血病细胞也表现出强大的细胞毒性。
