Four new lignanamides, hancamides A - D (1-4), together with four known analogs (5-8), were isolated from the stems of Piper hancei Maxim. Their structures were determined based on 1D and 2D NMR, IR, UV, and HR-ESIMS spectroscopic analysis as well as by comparison with the reported data. All the isolates exhibited potential inhibitory effects on NO production in LPS-induced BV-2 microglial cells, with IC values of 4.26-40.68 μM. Moreover, compounds 2 and 8 displayed moderate cytotoxic activities against MGC-803, HepG2, SKOV-3, T24, and HeLa cells, with IC values ranging from 13.57 to 34.20 μM, respectively.
从 Piper hancei Maxim 的茎中分离得到了四个新的木脂酰胺,汉酰胺 A-D(1-4),以及四个已知的类似物(5-8)。根据 1D 和 2D NMR、IR、UV 和 HR-ESIMS 光谱分析以及与报道数据的比较,确定了它们的结构。所有分离物均显示出对 LPS 诱导的 BV-2 小胶质细胞中 NO 产生的潜在抑制作用,IC 值为 4.26-40.68 μM。此外,化合物 2 和 8 对 MGC-803、HepG2、SKOV-3、T24 和 HeLa 细胞表现出中等的细胞毒性活性,IC 值范围分别为 13.57-34.20 μM。
