Methoxypoly(ethylene glycol) Poly(caprolactone) (mPEG–PCL) copolymers are important synthetic biomedical materials with amphiphilicity, controlled biodegradability, and great biocompatibility. They have great potential application in the fields of nanotechnology, tissue engineering, pharmaceutics, and medicinal chemistry. mPEG–PCL copolymers are biodegradable, biocompatible, and semi-crystallin...

Objectives We aimed to develop a sustained release system for an anti-TNFa drug in treatment of chronic inflammatory arthritis. A novel form of intra-articularly injectable etanercept (ETN) loaded poly(ε-caprolactone) (PCL) or methoxy poly(ethylene glycol)-poly(ε-caprolactone)methoxy poly(ethylene glycol) (MPEG-PCL-MPEG) microspheres (patent pending) were prepared to provide long term controlle...

An in situ-forming gel system comprised of diblock copolymer formed from polyethylene glycol (PEG) and polycaprolactone (PCL) {MPEG-b-(PCL-ran-PLLA)} could be used in controlled drug delivery for tissue remodeling. The purpose of this study is to demonstrate favorable vocal folds (VF) regeneration by using MPEG-b-(PCL-ran-PLLA) diblock copolymers (C97L3; CL/LA ratio 97:3) incorporating hepatocy...

Dimethoxycurcumin (DMC) is an analog of curcumin with superior efficacy in various disease models. Currently, drug delivery system research on DMC is very limited, and it has become a huge challenge to realize further developments and clinical applications. In the present study, a kind of amphiphilic block copolymer, N-t-butoxycarbonyl-phenylalanine terminated monomethoxyl poly (ethylene glycol...

In this study the bioactivity of hydroxyapatite/poly(ε-caprolactone)–poly(ethylene glycol) bilayer coatings on Nitinol superelastic alloy was investigated. The surface of Nitinol alloy was activated by a thermo-chemical treatment and hydroxyapatite coating was electrodeposited on the alloy, followed by applying the polymer coating. The surface morphology of coatings was studied using FE-SEM and...

This work aimed to investigate the effects of curcumin (Cur) encapsulated in triblock copolymer nanomicelles on lncRNA GAS5 expression and NF-κB signalling pathway ischemic stroke rats. Using polycaprolactone (PCL), polyethylene (mPEG), polyglutamic acid (PLG), Cur as raw materials, Cur-PLG-mPEG-PCL nanoparticles were prepared. Its morphology, particle size, Zeta potential analyzed. Then sevent...
