Non‐oxidized and oxidized flaxseed orbitides differently induce HepG2 cell apoptosis: involvement of cellular uptake and membrane death receptor DR4

Flaxseed orbitides have health‐promoting properties, particularly potent anti‐cancer activity. However, flaxseed orbitides containing a methionine structure, such as [1‐9‐NαC]‐linusorb B2 (CLB), are easily oxidized to sulfoxide ([1‐9‐NαC],[1‐Rs,Ss‐MetO]‐linusorb‐B2 (CLC)) and sulfone… Click to show full abstract

Flaxseed orbitides have health‐promoting properties, particularly potent anti‐cancer activity. However, flaxseed orbitides containing a methionine structure, such as [1‐9‐NαC]‐linusorb B2 (CLB), are easily oxidized to sulfoxide ([1‐9‐NαC],[1‐Rs,Ss‐MetO]‐linusorb‐B2 (CLC)) and sulfone ([1–9‐NαC], [1‐MetO]‐linusorb B2 (CLK)), with CLC having less anti‐cancer ability than CLB. It is unclear why oxidized flaxseed orbitides are less effective against cancer than non‐oxidized flaxseed orbitide.
