Self-assembly of amphiphilic helical-coiled peptide nanofibers and inhibition of fibril formation with curcumin
Bioorg Med Chem Lett. 2024 Mar 1:129682. doi: 10.1016/j.bmcl.2024.129682. Online ahead of print.ABSTRACTAmphiphilic peptide sequences are conducive to secondary structures that self-assemble into higher-ordered peptide nanostructures. A select set of amphiphilic polycationic peptides displayed stable helical-coiled structures that self-assembled into peptide nanofibers. The progression of peptide fibril formation revealed short protofibrils that extended into thin filaments and into an entangled network of nanofibers over an extended (5 days) incubation period. Ligand binding with 8-anilinonaphthalene-1-sulfonic acid (ANS)...

Double network self-healing hydrogels based on carboxyethyl chitosan/oxidized sodium alginate/Ca < sup > 2+ < /sup > : Preparation, characterization and application in dye absorption
Int J Biol Macromol. 2024 Feb 29:130564. doi: 10.1016/j.ijbiomac.2024.130564. Online ahead of print.ABSTRACTThis paper presents the formation of a self-healing hydrogel prepared by carboxyethyl modification of chitosan and crosslinking with oxidized sodium alginate. Concurrently, the incorporation of Ca2+ facilitated the formation of "calcium bridges" through intricate coordination with carboxyl moieties, bolstering the attributes of the hydrogel. Various characterization methods, including scanning electron microscopy, texture analysis, and rheological measurements, demonstrated that the introduction of carboxyethyl group...
