Abstract
Two new flavonoids, Alpinetin-7-O-[3''-O-galloyl-4'',6''-hexahydroxy-diphenoyl]-β-D-glucose (1), Pinocembrin-7-O-[4''-O-galloyl]-β-D-glucose (2), and three known compound (3-5) were isolated from Penthorum chinense Pursh (Saxifragaceae). The structures of all compounds were deduced from their comprehensive spectroscopic analysis including IR, HR-ESI-MS,1H NMR,13C NMR, DEPT, COSY, HMBC and HMQC. Molecular docking model was used to test the anti-cholestatic liver activities of the isolated compounds, and compounds 1 and 2 showed higher docking scores (-9.90 and -11.27 kcal/mol, respectively) binding with FXR than 3, 4 and 5 (-8.00, -9.77, -9.10 kcal/mol, respectively), suggesting 1 and 2 exhibited potential anti-cholestatic activities. The present results show that P. chinense is a potential source of 2 new lead compounds that can be utilised to produce therapeutic drugs for liver diseases upon further studies.
期刊介绍:
The aim of Natural Product Research is to publish important contributions in the field of natural product chemistry. The journal covers all aspects of research in the chemistry and biochemistry of naturally occurring compounds.
The communications include coverage of work on natural substances of land and sea and of plants, microbes and animals. Discussions of structure elucidation, synthesis and experimental biosynthesis of natural products as well as developments of methods in these areas are welcomed in the journal. Finally, research papers in fields on the chemistry-biology boundary, eg. fermentation chemistry, plant tissue culture investigations etc., are accepted into the journal.
Natural Product Research issues will be subtitled either ""Part A - Synthesis and Structure"" or ""Part B - Bioactive Natural Products"". for details on this , see the forthcoming articles section.
All manuscript submissions are subject to initial appraisal by the Editor, and, if found suitable for further consideration, to peer review by independent, anonymous expert referees. All peer review is single blind and submission is online via ScholarOne Manuscripts.
