Abstract

We report an efficient therapeutic approach to inhibit the migration and growth of vascular smooth muscle cells (VSMCs) via a low-dose sustained elution of a water-insoluble drug, demethoxycurcumin (DMC), through a self-assembled amphiphilic carbomethyl-hexanol chitosan (CHC) nanomatrix. Manipulating the cellular internalization and controlled cytotoxic effect of DMC-CHC nanoparticles over the VSMCs was elucidated. The DMC-CHC nanoparticles, which were systematically characterized in terms of structural morphology, surface potential, encapsulation efficiency, and DMC nanocrystallite distribution, exhibited rapid cellular uptake efficiency and considerably improved cytotoxic potency by 2.8 times compared to the free DMC. Under a cytotoxic evaluation, an improved antiproliferative effect and effective inhibition of VSMC migration as a result of highly efficient intracellular delivery of the encapsulated DMC in comparison to free DMC was achieved, which also was confirmed with a subsequent protein analysis. Cellular drug release and distribution of DMC after internalization into VSMCs was experimentally determined. This work may open a potential intracellular medicinal strategy with improved biological and therapeutic efficacy using the DMC-CHC nanoparticles illustrated in this work.
