Two new isobenzofuranone derivatives, polyphthaliside A (1) and polyphthaliside B (2), and a new isocoumarin derivative, polyisocoumarin (3), were isolated from Polygonum cuspidatum. Their structures were elucidated by detailed spectroscopic analysis and chemical methods. The cytotoxicity activity and PTP1B inhibitory activity of compounds 1-3 were estimated and none of them exhibited activities at
从虎杖中分离出两种新的异苯并呋喃酮衍生物,聚邻苯二酚A(1)和聚邻苯二酚B(2),以及新的异香豆素衍生物,聚异香豆素(3)。通过详细的光谱分析和化学方法阐明了它们的结构。估计化合物1-3的细胞毒性活性和PTP1B抑制活性,并且它们在10μM的浓度下均不表现出活性。
