US Patent No. 9,872,825 B2; Osaka University of Japan has been awarded a US patent for a peptide consisting of the amino acid sequence ELKLIFLHRLKRLRKRLKRK (SEQ ID NO: 1), or a derivative or salt of the peptide. The derivative has a modification selected from C-terminal amidation or esterification, protection of an N-terminal amino group with a protecting group, protection of a substituent on an amino acid side chain in the molecule with a protecting group, a combination of C-terminal amidation or esterification and protection of an N-terminal amino group with a protecting group, a combination of C-terminal amidation or esterification and protection of a substituent on an amino acid side chain in the molecule with a protecting group, a combination of protection of an N-terminal amino group with a protecting group and protection of a substituent on an amino acid side chain in the molecule with a protecting group, and a combination of C-terminal amidation or esterification, protection of an N-terminal amino group with a protecting group and protection of a substituent on an amino acid side chain in the molecule with a protecting group.
