It exhibits neuroprotective activity, slowing amyloid β peptide-induced damage in differentiated neuronal cells SH-SY5Y, and can be used in the study of neurological disorders such as Alzheimer's disease.

(+)-Secoisolariciresinol is a natural lignan exhibiting inhibitory activity against α-amylase (IC50=9.5 μM). (+)-Secoisolariciresinol is the enantiomer of (-)-Secoisolariciresinol and may be employed in biochemical experiments and drug synthesis research.

2,7 -Phloroglucinol-6,6'-bieckol serves as an effective oral dual α-amylase α-glucosidase inhibitor, demonstrating IC 50 concentrations of 6.94 μM and 23.35 μM, respectively. This compound is beneficial in mitigating postprandial hyperglycemia among diabetic mice and is applicable in diabetes research [1].
