    摘要: In some embodiments, the disclosure provides a hazelnut-derived peptide with an inhibitory activity against a 2019 novel coronavirus main protease (2019-nCoV M-pro), including an amino acid sequence of Trp-Trp-Asn-Leu-Asn (WWNLN). In other embodiments, the disclosure provides use of the hazelnut-derived peptide with an inhibitory activity against a 2019-nCoV M-pro in preparation of a drug, a health product, or a food supplementary for inhibiting a 2019-nCoV infection. In further embodiments, the derived peptide WWNLN in the disclosure has a high 2019-nCoV M-pro inhibitory activity, with an inhibition rate of 74.13%±1.93% and a half maximal inhibitory concentration (IC50) value of 6.695 μM. In some embodiments, the derived peptide may be used to prepare drugs, health products, or foods supplementary that inhibit 2019-nCoV infections, and may show desirable application prospects.
