However, in the study of Lee and Jun [236], the 8,8′-bieckol from E. cava demonstrated a high inhibitory effect against β-Secretase and acetylcholinesterase, which are the principal factors for the development of the Alzheimer’s disease, with interesting docking assays to advance this compound even further as a drug candidate for the therapeutics of Alzheimer′s disease. Here, ACHE is linked to early-onset autosomal dominant Alzheimer disease.
