Implication

In vitro study demonstrates enhanced stability of hydrazone ligation on colloidal onion vectors, highlighting their potential for targeted therapeutic delivery.

Key Points

To measure the kinetics and thermodynamic stability of α-oxohydrazone ligation bonds in solution and colloidal assemblies for targeting drug delivery vectors.
Characterized reaction kinetics and thermodynamic stability of model hydrazone formation across homogeneous solutions and self-organized colloidal systems, including micelles, liposomes, and multilamellar onion vectors.
Coupled RGD targeting peptides to onion vectors via hydrazone ligation and evaluated binding capacity toward endothelial cells in vitro.
Hydrazone bonds achieved submicromolar thermodynamic stability and prolonged half-lives lasting several weeks in aqueous solution.
Reaction rates and bond stability both increased in colloidal media relative to solution due to autoassociation effects.
RGD-functionalized onion vectors successfully maintained targeted binding affinity to endothelial cells in vitro.
