Gramicidin S (Gramicidin soviet) is a cationic cyclic peptide antibiotic that selectively targets bacterial cell membranes and has anticancer activity. Gramicidin S also exerts antibacterial activity by destroying membrane integrity and interfering with membrane protein function. Gramicidin S inserts into the phospholipid bilayer through hydrophobic amino acid residues, specifically binds to negatively charged membrane lipids and disrupts membrane structure, thereby inhibiting cell division and cell wall synthesis, and ultimately causing bacterial death. Gramicidin S also inhibits ion channels, with IC50s of 41 μM, 24 μM, and 3 μM for Na +/K +-ATPase, tobacco leaf plasma membrane Mg 2+/K +-ATPase, and rat heart plasma membrane Ca 2+-ATPase, respectively .

L17E is an attenuated cationic amphiphilic lytic (ACAL) peptide that can be used to deliver a variety of macromolecules, including proteins, antibodies, and DNA nanostructures. L17E inserts and cleaves the membrane structure through electrostatic interaction, enabling intracellular escape. The efficiency of L17E-mediated delivery is strongly correlated with the expression level of KCNN4 (the gene encoding the calcium-activated potassium channel KCa3.1). L17E also promotes the cellular uptake of macromolecules by inducing micropinocytosis. L17E can be further optimized and improved through dimerization strategies and in combination with other delivery systems, such as nuclear localization signal peptides and cell membrane-coated nanoparticles .
