Chemical investigation of the marine sponge Dactylospongia elegans, collected from the South China Sea, afforded three new dimeric sesquiterpene quinones, popolohuanones G - I (1 - 3), together with two known analogs, popolohuanones B (4) and C (5). The new structures were determined by HR-ESI-MS and 1D- and 2D-NMR analyses. All the five compounds showed no cytotoxic activity against five human cancer cell lines, while popolohuanone H (2) showed potent inhibitory activity against IL-6, an inflammatory cytokine, at the concentration of 10 μm.
对采自中国南海的海洋海绵优雅指海绵（Dactylospongia elegans）进行化学研究，得到了三种新的二聚倍半萜醌类化合物，波波洛环酮G - I（1 - 3），以及两种已知类似物，波波洛环酮B（4）和C（5）。通过高分辨电喷雾电离质谱（HR-ESI-MS）以及一维和二维核磁共振（1D-和2D-NMR）分析确定了新化合物的结构。所有这五种化合物对五种人类癌细胞系均无细胞毒性活性，而波波洛环酮H（2）在浓度为10 μM时对炎症细胞因子白细胞介素-6（IL-6）显示出强效抑制活性。
