Linum usitatissimum; acetylation; carbohydrates; chemical structure; cytotoxicity; free radicals; lignans; neoplasms; phenol; seeds
Abstract:
... The relationship between the chemical structure and DNA-protector and cytotoxic activities of phenylpropane lignans was studied. Analogs were synthesized from the lignan secoisolariciresinol diglucoside (SDG) isolated from Linum usitatissimum seeds. It was shown that SDG derivatives secoisolariciresinol and secoisolariciresinol-4′,4″-diacetate, which were not glucosides, exhibited greater cytotoxi ...
