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.
