Abstract:Die Entwicklung Redox-ausgelöster Peptidhydrogele ist mit fundamentalen Herausforderungen verknüpft, da hoch spezifische Peptidarchitekturen benötigt werden, was unvermeidlich in einer Limitierung der Vielseitigkeit solcher Materialien resultiert. Ein vielversprechender, jedoch selten genutzter Ansatz, um diese Hürden zu überwinden, ist die Nutzung einer vermittelnden Redoxreaktion zur kontrollierten Absenkung des pH-Werts während der Hydrogelbildung. Hier beschreiben wir eine vielseitige Strategie zum Auslöse… Show more
“…They can be incorporated as side chains, terminal groups, or linkages connected with conjugates using the amino acid l -methionine or through the etherification of l -cysteine. 23,55–57 The oxidation of ROS-sensitive polypeptides also modulates the hydrophobicity and assembly properties leading to different aggregate states, secondary structures and micro/macro-structural properties of the final material. Deming and co-workers studied the self-assembly of amphiphilic peptides consisting of poly( l -methionine) 65 - b -poly( l -leucine 0.5 - stat - l -phenylalanine 0.5 ) 20 , named M 65 (L 0.5 /F 0.5 ) 20 , which showed α-helix conformation in this hydrophobic state.…”

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
