Le staphylocoque doré est une des bactéries la plus présente dans notre environnement et elle peut causer diverses pathologies. L'Homme a mis au point des molécules biocides afin de contrer les bactéries pathogènes qui constitue la classe des antibiotiques. A cause de la résistance bactérienne, les antibiotiques ont des applications de plus en plus limitées et il est nécessaire de trouver des alternatives. Une alternative est l'utilisation de peptide antimicrobien et un peptide antimicrobien en particulier est la Pro3-TL. Néanmoins, ces peptides ne peuvent pas être administrés directement par voie orale, il est donc nécessaire d'encapsuler ceux-ci dans des microgels afin de les protéger des enzymes de la sphère intestinale. Par soucis environnemental, ces microgels sont synthétisés en CO2 supercritique qui est une technique permettant de se passer de solvant. Néanmoins, un agent de stabilisation doit être préalablement synthétisé afin de permettre la bonne dispersion de ces microgels. Cet agent de stabilisation possède une partie poly(oxyde d'éthylène) (PEO) et une partie poly(acrylate de perfluorodécyle) (PFDA) avec, entre ces deux parties, un groupement photo-clivable qui aura sont importance dans la suite. Une fois ces microgels synthétisés, des tests antibactériens vont être effectués afin de déterminer la cinétique de relargage du peptide au travers les pores du microgels. Dans un deuxième temps, grâce au clivage du bloc fluoré, il est possible de réalisé une amination réductrice, à la surface des microgels, entre l'amine terminale d'un peptide et l'aldéhyde formée à la surface des microgels lors du clivage de la partie fluorée. Il sera donc possible de cibler spécifiquement les staphylocoques dorés en greffant un peptide de ciblage à leur surface.

This Special Issue Book, “Marine Bioactive Peptides: Structure, Function, andTherapeutic Potential"" includes up-to-date information regarding bioactivepeptides isolated from marine organisms. Marine peptides have been found invarious phyla, and their numbers have grown in recent years. These peptidesare diverse in structure and possess broad-spectrum activities that have greatpotential for medical applications. Various marine peptides are evolutionaryancient molecular factors of innate immunity that play a key role in host defense.A plethora of biological activities, including antibacterial, antifungal, antiviral,anticancer, anticoagulant, endotoxin-binding, immune-modulating, etc., makemarine peptides an attractive molecular basis for drug design. This Special IssueBook presents new results in the isolation, structural elucidation, functionalcharacterization, and therapeutic potential evaluation of peptides found inmarine organisms. Chemical synthesis and biotechnological production of marinepeptides and their mimetics is also a focus of this Special Issue Book.
