Lapathoside A Isolated from Fagopyrum esculentum Induces Apoptosis in Human Pancreatic Cancer Cells.[Pubmed:33517279]
Anticancer Res. 2021 Feb;41(2):747-756.
BACKGROUND/AIM: Lapathoside A, a phenylpropanoid ester, was isolated from the roots of buckwheat by searching for bioactive compounds against human pancreatic cancer cells. MATERIALS AND METHODS: Buckwheat root extracts, prepared by 70% ethanol, were separated into n-hexane, methylene chloride, ethyl acetate, n-butanol, and water fraction by solvent partitioning. Seven fractions were obtained from the ethyl acetate fraction by liquid chromatography, and fraction No. 6 contained Lapathoside A. The effects of Lapathoside A on Panc-1 and SNU-213 human pancreatic cancer cell lines were examined. RESULTS: The structure of Lapathoside A was determined by liquid chromatography-mass spectrometry, liquid chromatography-tandem mass spectrometry, and nuclear magnetic resonance analysis. Next, we investigated whether Lapathoside A has anticancer activity in human pancreatic cancer cell lines (PANC-1 and SNU-213). After treatment with 25 muM Lapathoside A, viability of PANC-1 and SNU-213 cells decreased to about 40 and 27%, respectively. In addition, Lapathoside A treatment also increased apoptosis while affecting the expression levels of apoptotic proteins. CONCLUSION: The effect of Lapathoside A on apoptosis was confirmed in pancreatic cancer cell lines, supporting the application of Lapathoside A in the treatment of pancreatic cancer.
New phenylpropanoid esters of sucrose from Polygonum lapathifolium.[Pubmed:11678656]
J Nat Prod. 2001 Oct;64(10):1305-8.
Four new phenylpropanoid esters of sucrose, lapathosides A (1), B (2), C (3), and D (4), were isolated from the aerial parts of Polygonum lapathifolium together with known esters, vanicoside B (5) and hydropiperoside (6). The structures of 1-4 were determined by spectral (1D and 2D NMR and MS) analysis. Lapathoside A (1) and vanicoside B (2) showed significant inhibitory effects on the Epstein-Barr virus early antigen activation by tumor-promoters.
Cancer chemopreventive activity of phenylpropanoid esters of sucrose, vanicoside B and lapathoside A, from Polygonum lapathifolium.[Pubmed:11597787]
Cancer Lett. 2001 Nov 28;173(2):133-8.
To search for cancer chemopreventive agents from natural resources, many phytochemicals have been screened using the in vitro synergistic assay indicated by the inhibitory effects on the induction of Epstein-Barr virus early antigen (EBV-EA) by 12-O-tetradecanoylphorbol-13-acetate (TPA). Two phenylpropanoid esters of sucrose, vanicoside B and Lapathoside A, were isolated from the aerial part of Polygonum lapathifolium as inhibitors on the EBV-EA induction. These compounds also exhibited significant anti-tumor-promoting effects on mouse two-stage skin carcinogenesis induced by 7,12-dimethylbenz[a]anthracene (DMBA, as an initiator) and TPA as a promoter. Further, vanicoside B exhibited the remarkable inhibitory effect on two-stage carcinogenesis test of mouse skin tumors initiated with an NO donor, NOR-1.
