Application

Biocompatible, amphiphilic block copolymer composed of a hydrophilic PEG block and a hydrophobic poly(D,L-lactide) (PLA) block. These materials have been used in control release and nanoparticle formulation for drug encapsulation and delivery applications. Well-defined materials with varying properties can be prepared by controlling the relative length of each polymer block. Hydroxyl termination allows for facile further chemical modification of these materials.

Somatostatin analogue octreotide (OCT)-modified PEG-b-PLA micelles were constructed to bind to somatostatin receptors (SSTRs) overexpressed on tumor cells for enhanced intracellular drug delivery and improved therapeutic efficacy for malignant tumors. Copolymers conjugated with octreotide (OCT-PEG₆₀₀₀-b-PLA₅₀₀₀) were synthesized. The fluorescent probe

To develop an efficient tumor vasculature-targeted polymeric micelle delivery system for combretastatin A4 (CA4), a novel antivascular agent. CA4-loaded micelles were prepared from poly (ethylene glycol)-b-poly (d, l-lactide) copolymers. RGD peptides that target integrins alphavbeta3 and alphavbeta5, markers of angiogenic

Current clinical and preclinical anticancer formulations are limited by their use of toxic excipients and stability issues upon combining different drug formulations. We have found that poly(ethylene glycol)-block-poly(d,l lactic acid) (PEG-b-PLA) micelles can deliver multiple poorly water-soluble drugs at clinically
