摘要: 采用色谱柱层析及半制备高效液相色谱的分离方法,以及质谱和核磁共振波谱的鉴定方法,从蒟子全株中分离、鉴定出了10个化合物,其中4个为新的酰胺类成分,即蒟子酰胺A~D(1~4)。已知化合物包括3个二肽,即短蒟酰胺C~E(5~7),以及3个酰胺,即(E)-N-(3,4,5-三甲氧基肉桂酰基) 四氢吡咯(8)、(E)-N-(5-甲氧基-3,4-亚甲二氧基肉桂酰基) 四氢吡咯(9)和(Z)-N-(3,4,5-三甲氧基肉桂酰基) 四氢吡咯(10)。采用MTS法测试了4个新化合物对5种肿瘤细胞株的体外细胞毒活性,蒟子酰胺A(1)对人白血病HL-60细胞(IC50=10.99 μM)、人肝癌SMMC-7721细胞(IC50=17.10 μM)、人肺癌A-549细胞株(IC50=7.93 μM)、人乳腺癌MCF-7细胞(IC50=16.63 μM)和人结肠癌SW480细胞(IC50=9.16 μM)的生长有抑制活性。

Abstract: Through column chromatography and semi-preparative high performance liquid chromatography (HPLC),10 compounds were isolated from the whole plants of Piper yunnanense.These compounds including four new amides,namely piperunnamides A-D (1-4),along with three known dipeptides,pipermullamides C-E(5-7),and three known amides,(E)-N-(3,4,5-trimethoxycinnamoyl)pyrrolidine(8),(E)-N-(5-methoxy-3,4-methylenedioxycinnamoyl)pyrrolidine(9),and (Z)-N-(3,4,5-trimethoxycinnamoyl)pyrrolidine(10).Their structures were elucidated by MS and NMR spectra.The cytotoxic activity against five tumor cell lines of these new compounds was evaluated by an MTS assay.The result showed that piperunnamide A (1) exhibited growth inhibitory activity against human leukemia HL-60 (IC50=10.99 μM) cell line,human liver cancer SMMC-7721 (IC50=17.10 μM) cell line,human lung cancer A-549 cell line (IC50=7.93 μM),human breast cancer MCF-7 cell line (IC50=16.63 μM),and human colon cancer SW480 cell line (IC50=9.16 μM).
