Abstract:
Introduction. Gramicidin S has been conventionally manufactured as buccal tablets. However, in the past decade, the interest in the development of spray formulations has been growing. Those formulations contain excipients that enhance the solubility of the antibiotic in water solutions. However, the real structure of gramicidin S containing sprays remains unrevealed.Aim.

Abstract:
Two molecules of gramicidin S, a very rigid cyclic decapeptide rich in beta-sheet structure, can bind in a Ca2+-dependent way to a calmodulin molecule in the presence as well as in the absence of 4 M-urea. The flow-microcalorimetric titration of 25 microM-calmodulin with gramicidin S at 25 degrees C is endothermic for 21.3 kJ.mol-1; the enthalpy change is strictly linear up to a ratio of 2, indicating that the affinity constant for binding of the second gramicidin S is at least 10(7) M-1. In 4 M-urea the peptide quantitatively displaces seminalplasmin from calmodulin, as monitored by tryptopha

Abstract:
Background: Natural antimicrobial peptides are used in the fight against pathogens resistant to existing synthetic antibiotics. The non-specific mechanism of cytostatic action of antimicrobial peptides, in particular gramicidin S, against bacteria is also effective for damaging the cells of neoplasms. The existence of such a property in a registered antibiotic will indicate its antineoplastic potential and can be used to expand the spectrum of its therapeutic application. Aim of work is to clarify the possible antitumor effect of the antimicrobial peptide gramicidin S. Materials and Methods: U

Abstract:
Background/Objectives: Multidrug-resistant Gram-negative ESKAPE pathogens, including E. coli, K. pneumoniae, P. aeruginosa, and A. baumannii, pose a significant global health threat. Gramicidin S, a potent cyclic antimicrobial peptide, is largely ineffective against these bacteria, and its high haemolytic toxicity limits its clinical usage. This study reports on several novel gramicidin S analogues with improved efficacy and safety profiles against multidrug-resistant Gram-negative bacteria. Methods: A total of 19 gramicidin S derivatives were synthesised using Fmoc-based solid-phase peptide s

Abstract:
ABSTRACT Polymyxins B and E1 and gramicidin S are bacterium-derived cationic antimicrobial peptides. The polymyxins were more potent than gramicidin S against Pseudomonas aeruginosa, with MICs of 0.125 to 0.25 and 8 μg/ml, respectively. These peptides differed in their affinities for binding to lipopolysaccharide, but all were able to permeabilize the outer membrane of wild-type P. aeruginosaPAO1 strain H103, suggesting differences in their mechanisms of self-promoted uptake. Gramicidin S caused rapid depolarization of the bacterial cytoplasmic membrane at concentrations at which no killing wa

Abstract:
Enzymatically formed peptides show positional variations as well as highly conserved amino acids. In the cases of gramicidin S, tyrocidine, linear gramicidins, enniatins, echinocandins and viridogrisein in vivo and in vitro studies indicate substrate selection at the level of amino acid activation as a major control step. Evidence for proof-reading steps beyond activation has been obtained in penicillin and cyclosporin biosynthesis. Activated substrate analogues may promote the formation of side products such as dipeptides and cyclodipeptides. Modifications of intermediates, such as N-methylat

Much of the problem lies with the resistance that develops against conventional treatments due to the formation of mature biofilms. Thus the focus has shifted from the removal of biofilms to the prevention of initial attachment of organisms. This entails the use of antimicrobial surfaces tha

Abstract:
Cyclodextrins became famous for their ability to encapsulate chemical compounds, further modifying their properties. In present research, we focused on the mucoadhesion studies of gramicidin S and how it can be influenced by complex formation with hydroxypropyl-ß-cyclodextrin and chitosan. For the investigation, we applied the rheological method using the rotation viscometer. In accordance with the structural properties, hydroxypropyl-ß-cyclodextrin reduces the mucoadhesion of the peptide while chitosan increases. At the same time, both of these compositions can be considered as a possible way
