Background:

Secoisolariciresinol diglucoside is a plant lignan isolated from flaxseed, an antagonist of platelet activating factor-receptor, and used as an antioxidant.

Secoisolariciresinol diglucoside (SDG) inhibition of radiation induces DNA damage in irradiated lung cells. SDG (50 μM) significantly inhibits comet tail length in all cell types. Pre-treatment of SDG equally protects all three types of lung cells from radiation-induced DNA strand breaks. SDG (10-50 µM) alone does not elicit any adverse effect on the colony forming ability of all the three cell types as compared to their respective untreated control cells (100%)[2].

Secoisolariciresinol diglucoside (SDG, 15 mg/kg, p.o.) reduces hypercholesterolemic atherosclerosis of rabbits and this effect is releated to a decrease in serum cholesterol, LDL-C, and lipid peroxidation product and an increase in HDL-C and antioxidant reserve. SDG reduces total cholesterol (TC) and LDL-C by 33% and 35%, respectively, at week 8 but increases HDL-C significantly, by >140%, as early as week 4. It also decreases TC/LDL-C and LDL-C/HDL-C ratios by -64%. There is an increase in aortic malondialdehyde and chemiluminescence in group 3, and they are lower in group 4 than in group 3. SDG reduces hypercholesterolemic atherosclerosis by 73%[1].
