英文摘要 | Our random bioassay revealed that the CHCl3 part of Chelonopsis praecox (Lamiaceae) showed significant activity against alpha-glucosidase with the inhibitory rate of 99.6 +/- 0.4 % (330 mu g/mL). Bioassay-guided isolation yielded seven new ent-kaurane diterpenoids, chepraecoxins A-G (1-7), and three known ones (8-10), driven by LC-MS analyses. The structures of chepraecoxins A-G (1-7) were elucidated by X-ray crystallographic and extensive spectroscopic analyses. Compounds 1, 6, and 10 showed obvious alpha-glucosidase inhibitory effects with IC50 values of 305.0, 361.0 and 174.5 mu M, respectively. Enzyme kinetics study suggested that compound 1 inhibited the alpha-glucosidase by a noncompetitive type mechanism (K-i = 354.4 mu M). |
