Oral chemotherapy is a key step towards 'chemotherapy at home', a dream of cancer patients, which will radically change the clinical practice of chemotherapy and greatly improve the quality of life of the patients. In this research, three types of nanoparticle formulation from commercial PCL and self-synthesized d-α-tocopheryl polyethylene glycol 1000 succinate (PLA-PCL-TPGS) random copolymer w...

Lacrimal duct obstruction disease (LDOD) is a common ophthalmologic disease. Stent implantation surgery is one of the most effective therapies. In this study, we intended to find out the satisfactory biodegradable stents containing poly-L-lactic acid-polycaprolactone-polyethylene glycol (PLLA- PCL- PEG) complexes for therapeutic application in LDOD. Stents made of PLLA- PCL- PEG complexes in va...

BACKGROUND The combination of biliary stent with photodynamic and chemotherapy seemed to be a beneficial palliative treatment of unresectable cholangiocarcinoma. However, by intravenous delivery to the target tumor the distribution of the drug had its limitations and caused serious side effect on non-target organs. Therefore, in this study, we are going to develop a localized eluting stent, nam...

Angiogenesis is an essential process for disease progression in many solid tumors. There are several major cascade events in the angiogenic process that can be targeted to inhibit new blood vessel formation in the tumor tissue. The purpose of this work is to evaluate the inhibitory effect of paclitaxel (PTX) and rapamycin (RAP) as individual and in dual drug-loaded poly(ethylene glycol)-block-p...

Nucleic acid ligands (aptamers) are potentially well suited for the therapeutic targeting of drug encapsulated controlled release polymer particles in a cell- or tissue-specific manner. We synthesized a bioconjugate composed of controlled release polymer nanoparticles and aptamers and examined its efficacy for targeted delivery to prostate cancer cells. Specifically, we synthesized poly(lactic ...

Many tumor cells specifically overexpress somatostatin receptors, in particular, subtype 2 (SSTR2). Lanreotide, a somatostatin analogue with high affinity for SSTR2, can be exploited as a ligand for tumor targeted therapy. In this study, lanreotide was first conjugated to poly(ethylene glycol)-b-poly(ε-caprolactone) (PEG-b-PCL) copolymer, and the active targeting micelles with paclitaxel (lanre...

Abstract AIMS Synergistic combinations of doxorubicin and gemcitabine have been assessed for post-surgical treatment IDH1 wild-type glioblastoma (GBM). As a complementary drug carrier, hyperbranched micellar nanoparticles are being investigated to enable enhanced loading sustained release. METHOD 2D 3D spheroid in vitro models generated from patient-derived cells resected tumour core invasive m...
