Evaluation of cationic peptide-based nanogels as delivery systems for negatively charged molecules: a formulative study.

ABSTRACT: Peptide-based nanogels (NGs) represent a cutting-edge class of nanoscale drug delivery systems. Due to their structural properties, NGs platforms can encapsulate and protect therapeutic agents (e.g. peptides, proteins, and nucleic acids), while allowing for controlled and stimuli-responsive release. These pharmacokinetic and pharmacodynamic features can be specifically tuned by including peptide functional elements as NG components. This study explores the formulation, decoration strategies, and structural properties of NGs derived from mixed hydrogel (HG) matrices of Fmoc-diphenylalanine (Fmoc-FF) with cationic amphiphilic peptides (CAPs). CAPs, composed by cationic hexapeptide (GK)3 sequence decorated at its N-terminus with alkyl chain, were found able to confer a net positive charge to
