Description générale

It is a Polyethylene glycol (PEG) macromer with a reactive chain end consisting of methyl ether. Etherification of the PEG chain ends can be undertaken in basic conditions by reacting it with alkyl halides. mPEG can undergo cross linking to form hydrogels; polymerization can be initiated by redox reaction or free radical initiator.

Application

Poly(ethylene glycol) methyl ether-attached dendrimers can be used as carriers for anticancer drugs. This novel drug carrier has a biocompatible surface and an interior for the encapsulation of drugs.

It can be used as a pore-forming agent in the preparation of ultrafiltration membranes which are used in the removal of macromolecules.

It can also be used as a starting material in the preparation of a biodegradable amphiphilic copolymer of poly(L-alanine) with mPEG.

Caractéristiques et avantages

Inserting poly(ethylene glycol) methyl ether (mPEG) side chain enhances the hydrophilicity and flexibility of the polymer matrix.

To promote the application of methoxy poly(ethylene glycol)-cholesterol (mPEG-Chol), mPEG-Chol was used to prepare core-shell micelles encapsulating poorly water-soluble docetaxel (DTX-PM) by modified cosolvent evaporation method. Approaches to enhance DTX entrapment efficiency (EE) and minimize particle size were investigated in

A functionalized poly(amidoamine) (PAMAM) nanocarrier was designed and prepared to deliver anticancer drugs. The nanocarrier is a copolymer with a core-shell structure with 3.0 G PAMAM as the core and sequentially conjugated poly(2-(N,N-diethylamino)ethyl methacrylate) (pDEA) and methoxy-poly(ethylene glycol) 2000 (mPEG)

Although targeted delivery mediated by ligand modified or tumor microenvironment sensitive nanocarriers has been extensively pursued for cancer chemotherapy, the efficiency is still limited by premature drug release after systemic administration. Herein we report a highly blood-stable, tumor-adaptable drug carrier
