Biological Activity
Description: Sequosempervirin B is a natural product from Sequoia sempervirens.
In vitro:
Chem Biodivers. 2005 Apr;2(4):497-505.
Norlignans from Sequoia sempervirens.[Pubmed: 17191998 ]

METHODS AND RESULTS:
Six new norlignans, named Sequosempervirin B, sequosempervirin C,sequosempervirin D, sequosempervirin E, sequosempervirin F, sequosempervirin G (1-6), together with three known norlignans, agatharesinol (7), agatharesinol acetonide (8), and sugiresinol (9), were isolated from the branches and leaves of Sequoia sempervirens. Their structures were determined mainly by high-resolution mass spectroscopy (HR-MS), and various 1D- and 2D-NMR methods, as well as, in the case of 1, by means of X-ray diffraction.
CONCLUSIONS:
Compound 8 showed anticancer activity towards the A549 non-small-cell lung-cancer cell line (IC50 = 27.1 microM). The acetone extract of S. sempervirens was found to be antifungal towards Candida glabrata (IC50 = 15.98 microg/ml), and both the acetone and MeOH extracts inhibited the proteolytic activity of cathepsin B (IC50 = 4.58 and 5.49 microg/ml, resp.).
