Diarylheptanoids from Rhizomes of Alpinia officinarum Inhibit Aggregation of alpha-Synuclein.[Pubmed:28707886]
J Agric Food Chem. 2017 Aug 9;65(31):6608-6614.
Two new diarylheptanoids, alpinin A (1) and Alpinin B (2), together with 18 known diarylheptanoids (3-20), were isolated from the rhizomes of Alpinia officinarum. Their structures were elucidated by comprehensive spectroscopic analysis, including high-resolution mass spectrometry, infrared spectroscopy, and one- and two-dimensional nuclear magnetic resonance spectroscopy. Structurally, alpinin A is a new member of the small family of oxa-bridged diarylheptanoids and contains the characteristic 2,6-cis-configured tetrahydropyran motif (C1-C5 oxa bridge). The absolute configuration of alpinin A was confirmed by asymmetric total synthesis of the enantiomer (ent-1), corroborating the assignment of the molecular structure. The absolute configuration of Alpinin B was determined on the basis of the analysis of the circular dichroism exciton chirality spectrum. We evaluated the inhibitory activity of all isolated diarylheptanoids against alpha-synuclein aggregation at 10 muM. Alpinins A and B significantly inhibited alpha-synuclein aggregation by 66 and 67%, respectively.
A new dimeric diarylheptanoid from the rhizomes of Alpinia officinarum.[Pubmed:24636065]
Chin J Nat Med. 2014 Feb;12(2):139-41.
AIM: To study the chemical constituents of the rhizomes of Alpinia officinarum Hance. METHOD: Compounds were isolated by repeated column chromatography, and their structures were elucidated on the basis of spectral analysis. The cytotoxic activities of these compounds were evaluated with the T98G and B16F10 cell lines by the MTT assay. RESULTS: A dimeric diarylheptanoid, named Alpinin B (1), along with three known diarylheptanoids were obtained, and their structures were identified as Alpinin B (1), 1, 7-diphenyl-3,5-heptanedione (2), (4E)-1, 7-diphenylhept-4-en-3-one (3) and (4E)-7- (4-hydroxyphenyl)-1-phenylhept-4-en-3-one (4). CONCLUSION: Compound 1 is a new dimeric diarylheptanoid. The biosynthetic pathway of 1 was speculated to originate from a Michael reaction between compounds 2 and 3. Compound 3 showed cytotoxicity against the human glioblastoma T98G cell line with IC50 of 27 mumol.L(-1).
