Abstract

The present invention relates to the field of polymer chemistry and more particularly to multiblock copolymers and micelles comprising the same. Compositions herein are useful for drug-delivery applications.

Claims (14)

1. A micelle comprising a triblock copolymer, wherein said micelle has a drug-loaded inner core, a crosslinked outer core, and a hydrophilic shell, wherein the triblock copolymer is of formula VII:

wherein:

n is 20-500;

m is 1 or 2;

x 1 is 1-20;

x 2 is 0-20;

y is 5 to 100;

R y is selected from one or more natural or unnatural amino acid side chain groups such that the overall block is hydrophobic;

M is a metal ion;

R T is OCH 3 ; and

wherein the drug is a molecularly targeted therapeutic.

2. The micelle according to claim 1 , wherein the drug is a tyrosine kinase inhibitor.

3. The micelle according to claim 1 , wherein the drug is:

4. The micelle according to claim 1 , wherein the drug is:
