Abstract

In this study, the whole protein of Arthrospira (Spirulina) platensis was extracted and hydrolyzed with trypsin. Screening process for new peptides was driven by 2,2′-azinobis-3-ethylbenzothiazoline-6-sulfonic acid (ABTS) radical scavenging activity assay, and a hexapeptide with sequence of GMCCSR was identified. Its anti-oxidant activity was measured based on ABTS, 1,1’-diphenyl-2-picrylhydrazyl (DPPH), and ferric reducing ability of plasma (FRAP) assays. Hemolysis inhibition on human erythrocytes and collagen-stimulating activities on human skin fibroblasts (HSFs) were investigated. Results showed that its radical scavenging effect could compete with ascorbic acid. Intracellular assays revealed the reduction of reactive oxygen species (ROS) and malondialdehyde (MDA) contents and the increase in activities of superoxide dismutase (SOD), catalase (CAT), and glutathione peroxidase (GSH-Px) in erythrocytes pretreated with hexapeptide, demonstrating that the peptide could protect erythrocytes from lipid peroxidation and protein oxidation. Moreover, results from HSFs showed that it could promote proliferation and collagen production of HSFs pro-damaged by UVB. These results suggest the potential of the hexapeptide in food and pharmaceutical industries.
