Structurally Diverse Phenylpropanoid Glycosides with Anti-Rheumatoid Arthritis Activities from Vicatia thibetica
摘要
A new phenylpropanoid glycoside, named (7E)-1′-phenylethanol-6′-(3,5-dimethoxy-4-hydroxycinnamic acid) 3′′ ,4′′ -(11′′-carbonylfuran)-8′′ /11′′ -O-β-D-diglucopyranosylphenylpropanoid (1), and seven known phenylpropanoid glycosides (2–8) were isolated from Vicatia thibetica H. Boissieu for the first time. Their structures were elucidated by extensive spectroscopic methods (NMR, MS, UV, IR) and comparison with literature data. The anti-rheumatoid arthritis activities of these phenylpropanoid glycosides (1–8) were evaluated on a TNF-α induced MH7A human rheumatoid fibroblast-like synoviocyte model. Among them, compounds 1 and 2 exhibited important anti-rheumatoid arthritis activities.
