Anti-plasmin inhibitor. V. Structures of novel dimeric eckols isolated from the brown alga Ecklonia kurome Okamura.
摘要:
6, 6'-Bieckol (1), 2-O-(2, 4, 6-trihydroxyphenyl)-6, 6'-bieckol (4), and 8, 8'-bieckol (2), bispolyphenols with a dibenzo-1, 4-dioxin skeleton, have been isolated as potent anti-plasmin inhibitors from the brown alga Ecklonia kurome OKAMURA. Their structures have been determined to be dimers of eckol linked at the C-6 or C-8 positions, through an aryl-aryl bond on the basis of spectral data. Their inhibitory actions on anti-plasmins (α2-macroglobulin and α2-plasmin inhibitor) and some proteases have been examined.
Described herein are solid pharmaceutical compositions of brown algae extracts and methods for making solid pharmaceutical compositions of brown algae extracts. In some embodiments, the brown algae extract is derived from Ecklonia cava.
