fractionation of a methanolic extract of the Red Sea cucumber Holothuria spinifera and LC-HRESIMS-assisted dereplication resulted in the isolation of four compounds, three new cerebrosides, spiniferosides A (1), B (2), and C (3), and cholesterol sulfate (4). The chemical structures of the isolated compounds were established on the basis of their 1D NMR and HRMS spectral data. Metabolic profiling of the H. spinifera
生物活性指导的红海参Holholuria spinifera甲醇提取物的分馏和LC-HRESIMS辅助去复制导致了四种化合物,三种新的脑苷,Spiniferosides A(1),B(2)和C(3)的分离。和硫酸胆固醇(4)。分离出的化合物的化学结构是根据其1D NMR和HRMS光谱数据确定的。棘轮虫的代谢谱提取物表明存在多种次生代谢产物,主要是羟基脂肪酸,二萜,三萜和脑苷。测试分离的化合物对乳腺癌MCF-7细胞系的体外细胞毒性。化合物1,2,3,和4显示的有前途的细胞毒性活性对MCF-7细胞,用IC 50个的13.83值,8.13,8.27,和35.56微米,分别相比于标准药物多柔比星的(IC 50 8.64μM) 。另外,对于化合物进行对接研究1,2,3,和4阐明它们与SET蛋白活性位点的结合相互作用,SET蛋白是蛋白磷酸酶2A(PP2A)的抑制剂,这可以解释其细胞毒性活性。这项研究强
