Descrição geral

Block copolymer micelles are widely used in drug delivery applications. PEG-PDLLA is a biodegradable polymeric micelle which is used as a carrier for hydrophobic drugs like Paclitaxel. The hydrophilic PEG and hydrophobic PDLLA form the micelle core wherein the hydrophobic drug is loaded. The incorporation of the 10-alkyl end cap (decane) increases the hydrophobicity of the micelle core and increases its solubilizing capability for hydrophobic drugs.†

Aplicação

Used as a carrier for the controlled and targeted release of anticancer hydrophobic drugs.

Características e benefícios

  • Good biocompatibility, low immunogenicity and good degradability.
  • Properties can be easily modulated by changing the block copolymer segment sizes to suit a particular application.

This work describes the synthesis and characterization of novel thermoresponsive highly branched polyamidoamine-polyethylene glycol-poly(D,L-lactide) (PAMAM-PEG-PDLLA) core-shell nanoparticles. A series of dendritic PEG-PDLLA nanoparticles were synthesized through conjugation of PEG of various chain lengths (1500, 6000 and 12,000 g mol(-1)) to

It is generally assumed that polymeric micelles, upon administration into the blood stream, carry drug molecules until they are taken up into cells followed by intracellular release. The current work revisits this conventional wisdom. The study using dual-labeled micelles containing

One of the common difficulties with intravenous drug delivery is low solubility of the drug. The requirement for large quantities of saline to dissolve such materials limits their clinical use, and one solution for this problem that has recently generated interest is the formation of drug-loaded micelles.

Local delivery of bioactive molecules using an implantable device can decrease the amount of drug dose required as well as non-target site toxicities compared to oral or systemic drug administration.

Aliphatic polyesters such as polylactide, poly(lactide-co-glycolide) and polycaprolactone, as well as their copolymers, represent a diverse family of synthetic biodegradable polymers that have been widely explored for medical uses and are commercially available.

The development of drugs that target specific locations within the human body remains one of the greatest challenges in biomedicine today.
