Idarubicin-loaded methoxy poly(ethylene glycol)-b-poly(l-lactide-co-glycolide) nanoparticles for enhancing cellular uptake and promoting antileukemia activity.

ABSTRACT:

Purpose

Nanoparticle (NP)-based drug delivery approaches have tremendous potential for enhancing treatment efficacy and decreasing doses of chemotherapeutics. Idarubicin (IDA) is one of the most common chemotherapeutic drugs used in the treatment of acute myeloid leukemia (AML). However, severe side effects and drug resistance markedly limit the application of IDA.

Methods

In this study, we encapsulated IDA in polymeric NPs and validated their antileukemia activity in vitro and in vivo.

Results

NPs with an average diameter of 84 nm was assembled from a methoxy poly(ethylene glycol)-b-poly(l-lactide-co-glycolide) (mPEG-PLGA). After loading of IDA, IDA-loaded mPEG-PLGA NPs (IDA/mPEG-PLGA NPs) were formed. The in vitro release data showed that the IDA/mPEG-PLGA NP
