    • PURPOSE: A pseudin-derived antibacterial peptide analog Ps-6 is provided to increase cationic property and ensure antibacterial activity without cytotoxicity. CONSTITUTION: A peptide Ps-6 of sequence number 2 is prepared by substituting 11th glycin of pseudin-2 peptide into proline, and 10th, 14th, 18th, 24th residues to lysine. An antibacterial composition contains a peptide of sequence number 2 as an active ingredient. The antibacterial composition has effects to gram positive bacteria, gram negative bacteria or fungi. A pharmaceutical composition for anti-cancer contains the peptide of sequence number 2 as an active ingredient. The composition contains a peptide having 90% or more homology with a sequence in which 11th amino acid is preserved to a proline.
    • 目的:提供假性衍生的抗菌肽类似物Ps-6以增加阳离子性质,并确保抗细菌活性而不具有细胞毒性。 构成:将序列号2的肽Ps-6通过将第十一甘氨酸的假蛋白-2肽取代成脯氨酸,将第十,第十四,第十八,第二十四残基替换为赖氨酸。 抗菌组合物含有序列号2的肽作为活性成分。 抗菌组合物具有革兰氏阳性细菌,革兰氏阴性菌或真菌的作用。 用于抗癌的药物组合物含有序列号2的肽作为活性成分。 该组合物含有与将第11位氨基酸保留在脯氨酸中的序列具有90%以上同源性的肽。
