一般描述

它是聚乙二醇(PEG)大分子单体,具有由甲基醚组成的反应性链端。PEG链末端的醚化可以通过在碱性条件下使其与烷基卤化物进行反应来实现。mPEG可以进行交联以形成水凝胶;聚合反应可以通过氧化还原反应或自由基引发剂进行引发。

应用

插入聚(乙二醇)甲基醚结合的树状聚合物可作为抗癌药物的载体。这种新型药物载体具有生物相容性表面和药物的内部封装。

它可作为一种成孔剂,以制备用于去除大分子的超滤膜。

还可将其作为起始材料,用于制备生物可降解的聚(L-丙氨酸)与mPEG的两亲性共聚物。

特点和优势

插入聚(乙二醇)甲基醚(mPEG)侧链可增强聚合物基质的亲水性和柔韧性。

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

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

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
