{"title":"Characterization of a New Anti-dementia β-secretase Inhibitory Peptide from Arctoscopus japonicus","authors":"Seul Bit Na Park, S. Kim, H. Byun","doi":"10.17642/jcc.23.4.2","DOIUrl":"https://doi.org/10.17642/jcc.23.4.2","url":null,"abstract":"Amyloid plaque is a product of aggregation of β-amyloid peptide (Aβ) and is an important factor in the pathogenesis of Alzheimer’s Disease (AD). Aβ is a major component of amyloid plaque and vascular deposits in the AD brain. The enzyme β- secretase is required for the production of Aβ; thus, prevention of the formation of Aβ through the inhibition of β-secretase is a major focus in the study of the treatment of AD. In this study, we investigated β-secretase inhibitory activity of an Arctoscopus japonicus peptide. An Alcalase hydrolysate had the highest β-secretase inhibitory activity. A β-secretase inhibitory activity peptide was separated using ion exchange column chromatography (carboxy-methyl: CM, quaternary methyl ammonium: QMA) and reverse phase high performance liquid chromatography (RP-HPLC) on a C18 column. The IC50 value of the purified peptide was 248.2±1.73 μg/mL. The β-secretase inhibitory peptide was identified as a six amino acid residue of Gly-Pro-Val-Gly-Ala- Pro (MW: 497.27 Da). In cell viability experiments, the final purified fraction, the carboxy-methyl ion exchange column fraction (CM-F1) showed no significant cytotoxic effect in SH-SY5Y cells at concentrations below 100 μg/mL in 24 h. The results of this study suggest that peptides separated from Arctoscopus japonicus may be beneficial as β-secretase inhibitor compounds in functional foods.","PeriodicalId":15363,"journal":{"name":"Journal of Chitin and Chitosan","volume":"11 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2018-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74146166","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, the effect of purified neutral protease for deprotenization of fungal biomass studied at various levels (0, 5, 10, 20 and 40 U/100 mg of biomass) and the saccharification of fungal biomass was evaluated with amylolytic enzymes and chitosanases. The efficiency of deproteinization of fungal biomass was based on the enzyme concentration and contact time. Protease at a concentration of 20 U/100 mg of dry biomass and with a contact time of 8 h achieved 30% final deproteinization. No effect on saccharification of A. niger biomass was observed by treatment with purified amylolytic enzymes. Meanwhile, the endo- and exo-chitosanases treatment yielded 54 g of g reducing sugars (equivalent to amino sugars)/ kg of fungal biomass, which can be employed for tailor-made carbohydrate production.","PeriodicalId":15363,"journal":{"name":"Journal of Chitin and Chitosan","volume":"85 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2018-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89616020","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
