Xylarianaphthol-1, a novel dinaphthofuran derivative, was isolated from a marine sponge-derived fungus of order Xylariales on the guidance of a bioassay using the transfected human osteosarcoma MG63 cells (MG63(luc+)). The chemical structure of xylarianaphthol-1 was determined from the (1)H and (13)C NMR analysis and was further confirmed by the total synthesis. Xylarianaphthol-1 activated p21 promoter stably transfected in MG63 cells dose-dependently. Expression of p21 protein in the wild-type MG63 cells was also increased by xylarianaphthol-1 treatment.
木层孔萘酚-1是一种新型的二萘并呋喃衍生物,它是在利用转染的人骨肉瘤MG63细胞(MG63(luc+))进行生物测定的指导下,从一种属于炭角菌目的海洋海绵衍生真菌中分离得到的。通过(1)H和(13)C核磁共振分析确定了木层孔萘酚-1的化学结构,并通过全合成进一步证实。木层孔萘酚-1能剂量依赖性地激活稳定转染于MG63细胞中的p21启动子。用木层孔萘酚-1处理野生型MG63细胞也能增加p21蛋白的表达。
