Abstract

Official abstract text for this publication.

The present invention relates to a broken or kinked helical peptide or peptide analogue and the use thereof, and more particularly to a Gram-negative bacterial membrane-penetrating peptide or peptide analogue wherein an alpha-helical amphipathic peptide composed of hydrophobic amino acids and hydrophilic amino acids has a kinked structure, or an antimicrobial composition employing the specific activity of the peptide against the Gram-negative bacterial membrane, or an antimicrobial composition for co-administration, or a conjugate comprising a drug linked to the peptide or peptide analogue, or an antibiotic comprising the same.

First claim

Opening claim text (preview).

The invention claimed is: 1. A method for killing Gram-negative bacteria, comprising administering i) a Gram-negative bacterial membrane-penetrating peptide comprising the sequence of SEQ ID NO: 14, 19, 22 or 30 and ii) an antibiotic, wherein the antibiotic has an antimicrobial activity for Gram-positive bacteria. 2. The method of claim 1 , wherein the antibiotic having an antimicrobial activity for Gram-positive bacteria is cloxacillin or linezolid. 3. A method for killing Gram-negative bacteria, comprising administering i) a Gram-negative bacterial membrane-penetrating peptide comprising the sequence of SEQ ID NO: 14, 19, 22 or 30 and ii) a drug, wherein the drug is resveratrol, curcumin, ibuprofen, quercetin, simvastatin, lovastatin or atorvastatin.
