peptide gramicidinS (GS) is an effective topical antibacterial agent that is toxic for human red blood cells (hemolysis). Herein, we present a series of amphiphilic derivatives of GS with either two or four positive charges and characteristics ranging between very polar and very hydrophobic. Screening of this series of peptide derivatives identified a compound that combines effective antibacterial activity
The present disclosure relates to peptidic compounds of Formula A, A-II, A-III, B, or C, or salt or solvate thereof, compositions thereof, and methods of use thereof. The compounds of the present disclosure are useful for targeting CXCR4 for purposes such as imaging and/or therapeutics.
The present invention relates to antimicrobial cyclic peptides, which display a reduced hemolytic activity and optionally antimicrobial activity in comparison to parent antimicrobial cyclic peptides from which they are derived. In one embodiment the parent cyclic peptide is gramicidin S. There is also provided a method of providing novel derivative antimicrobial cyclic peptides which have been developed from a parent antimicrobial cyclic peptide and which display a reduced haemolytic activity and/or antimicrobial activity compared to the parent molecule from which they are derived.
