Descrizione generale
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.
Applicazioni
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.

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

The microcosmic mechanisms of protein (recombinant human growth hormone, rhGH) incomplete release and stability from amphiphilic poly(monomethoxypolyethylene glycol-co-D,L-lactide) (mPEG-PLA, PELA) microspheres were investigated. PELA with different hydrophilicities (PELA-1, PELA-2, and PELA-3) based on various ratios of mPEG to PLA were

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
