从南太平洋海绵Rhopaloeides odorabile和Hyrtios sp.中分离得到了包括溴吲哚在内的吲哚衍生物,并通过质谱、1D和2D NMR数据分析确定了它们的结构。评价了它们潜在的抑制磷脂酶A2(PLA 2)、抗氧化和细胞毒活性。从Hyrtios sp.分离的新衍生物5,6-二溴-1-下胡萝卜素(9)显示出弱的蜂毒PLA 2抑制(IC 50 0.2 mM)和显著的抗氧化活性,氧自由基吸收能力(ORAC)值为0.22。倍半萜aureol(4),也分离自Hyrtios sp.,显示出最有效的抗氧化活性,ORAC值为0.29。
Indole derivatives including bromoindoles have been isolated from the South Pacific marine sponges Rhopaloeides odorabile and Hyrtios sp. Their structures were established through analysis of mass spectra and 1D and 2D NMR spectroscopic data. Their potential inhibitory phospholipase A2 (PLA2), antioxidant and cytotoxic activities were evaluated. The new derivative 5,6-dibromo-l-hypaphorine (9) isolated from Hyrtios sp. revealed a weak bee venom PLA2 inhibition (IC50 0.2 mM) and a significant antioxidant activity with an Oxygen Radical Absorbance Capacity (ORAC) value of 0.22. The sesquiterpene aureol (4), also isolated from Hyrtios sp., showed the most potent antioxidant activity with an ORAC value of 0.29.
