Secoisolariciresinol diglucoside (SDG) is isolated from Linum usitatissimum seeds. The antiproliferative effects of SDG (1) and its derivatives secoisolariciresinol (2) and secoisolariciresinol-4′, 4″-diacetate (3) have been evaluated on MCF-7 breast cancer cells and normal breast epithelial line MCF-10A. Lignan 1 has not shown cytotoxic effects on MCF-7 cells, while derivatives 2 and 3 have inhibited cell growth with IC50 values of 25 and 11 μM, respectively. Estrogen receptor alpha is a key growth driver in MCF-7 cells. Compound 1 did not affect the activity of ERα, while derivatives 2 and 3 showed significant antiestrogenic effects. Compounds 2 and 3 caused apoptosis in the MCF-7 line, determined by the cleavage of PARP. SDG derivative 3 enhanced the effect of doxorubicin. SDG derivatives can be considered as promising agents that exhibit a combined antiestrogen and proapoptotic effect in hormone-dependent breast cancer cells.

For the first time, we describe the stereocontrolled total syntheses of olivil, cephafortin A, 4-des-O-methyl-4-O-rhamnosyl cephafortin A, and alashinol F from a common precursor using a combination of chemoenzymatic and biomimetic methods for the systematic introduction of functional groups on three vicinal stereogenic carbon atoms. We revised the previously assigned stereochemistry of (+)-cephafortin A, which was reported as the enantiomer. Natural and unnatural congeners provide insights into the biogenetic interrelations of members of this family.

Page/Page column 10, (2015/11/09)
Therapeutic compositions comprising at least one 8-substituted-dibenzylbutyrolactone lignan, preferably a lignan is selected from the group of nortrachelogenin, diasteromeric forms of nortrachelogenin, isomeric forms of nortrachelogenin and combinations thereof as well as 8-methylmatairesinol and 8-methyldimethylmatairesinol, for use in a method of treating cancer or a similar condition wherein the growth factor signaling pathway of a mammal is deregulated. The invention also provides therapeutic pharmaceutical combinations comprising a hydroxy-dibenzylbutyrolactone lignan and at least one TRAIL receptor agonist. The hydroxy-dibenzylbutyrolactone lignans and a TRAIL receptor agonist can be used as a combined preparation for administration to a patient simultaneously, separately or spaced out over a period of time in treating cancer.
