从唐古特普氏原羚(Przewalskiatangutica)全草中分得三个新的氯代酚苷,即普氏原羚苷A-C(1-3)沿着一个已知化合物globosumoside A(4)。通过光谱分析和化学方法确定了它们的结构。评价了分离的酚苷(1-4)对五种人癌细胞系A549、MCF-7、SMMC-7721、HepG 2和HL-60的细胞毒活性。普氏瓦当苷A(1)对SMMC-7721细胞有较弱的细胞毒作用,IC 50值为38.1 μM。所有受试化合物对正常人肝细胞系(L02)均无活性(IC 50> 50 μM)。
Three new chlorinated phenolic glycosides, namely przewatangosides A-C (1-3), along with one known compound, globosumoside A (4), were isolated from the whole plants ofPrzewalskia tangutica. Their structures were unequivocally determined by extensive spectroscopic analysis and chemical method. The cytotoxic activities of the isolated phenolic glycosides (1-4) were evaluated against the five human cancer cell lines A549, MCF-7, SMMC-7721, HepG2 and HL-60. Przewatangoside A (1) exhibited weak cytotoxicity against SMMC-7721 with the IC50value of 38.1 μM. All the tested compounds were inactive (IC50> 50 μM) to the normal human hepatocyte cell line (L02).
