  Secondary metabolites from the flower buds of Lonicera japonica and their in vitro anti-diabetic activities

  摘要：

  Four new compounds (1, 2, 7 and 8) and twenty known compounds were isolated from the flower buds of Lonicerajaponica. Their structures were determined by extensive NMR and HR-ESIMS spectroscopic data analyses. Among them, compounds 1 and 2 are a pair of diastereoisomers possessing a rare chemical structure, and their absolute configurations were determined by comparing their experimental and calculated ECD spectra. Furthermore, all the isolates were evaluated for their inhibitory effects on a-glucosidase and protein tyrosine phosphatase IB (PTP1B), especially 1 and 2, which displayed both significant inhibitions. In addition, the possible action mechanism of the active compounds was also explored by using molecular docking studies. (C) 2016 Elsevier B.V. All rights reserved.
