Abstract
Stearic acid esters of poly(ethylene oxide)-block-poly(hydroxyethyl L-aspartamide) and poly(ethylene oxide)-block-poly(hydroxyhexyl L-aspartamide) have been synthesized from poly(ethylene oxide)-block-poly(beta-benzyl L-aspartate) by polymer-analogous reactions and self-assembled into a micelle. Transmission electron microscopy and fluorescent probe studies reveal that the micelle mimics structural features of serum lipoproteins: it is nanoscopic, spherical, and has a supramolecular core-shell architecture, where the core is rich in fatty acid esters. As a result, the polymeric micelles effectively solubilize amphotericin B, a key drug for systemic mycoses. Serum lipoproteins solubilize many hydrophobic drugs as a biological transport system besides amphotericin B. A synthetic polymeric analogue may achieve the same aim, but with the ease of structural modification, safety, and stability.
