A biomimetic and pH-sensitive polymeric micelle as carrier for paclitaxel delivery
As nano-scale drug delivery systems, smart micelles that are sensitive to specific biological environment and allowed for target site-triggered drug release by reversible stabilization of micelle structure are attractive. In this work, a biocompatible and pH-sensitive copolymer is synthesized through bridging poly (2-methacryloyloxyethyl phosphorylcholine) (PMPC) block and poly (D, L-lactide) (...
متن کاملA fully absorbable biomimetic polymeric micelle loaded with cisplatin as drug carrier for cancer therapy
cis-dichlorodiammineplatinum(II) (CDDP)-loaded polymeric micelles for cancer therapy have been developed to reduce the serious side effects of cisplatin CDDP. Herein, polymeric micelles incorporated with cisplatin are prepared based on the complexation between CDDP and hydrophilic poly (L-glutamic acid)-b-poly (2-methacryloyloxyethyl phosphorylcholine) (PLG-b-PMPC) diblock copolymers. These CDD...
متن کاملLow molecular weight chitosan-coated polymeric nanoparticles for sustained and pH-sensitive delivery of paclitaxel.
Low molecular weight chitosan (LMWC) is a promising polymer for surface modification of nanoparticles (NPs), which can impart both stealth effect and electrostatic interaction with cells at mildly acidic pH of tumors. We previously produced LMWC-coated NPs via covalent conjugation to poly(lactic-co-glycolic) acid (PLGA-LMWC NPs). However, this method had several weaknesses including inefficienc...
متن کاملSuper pH-sensitive multifunctional polymeric micelle for tumor pH(e) specific TAT exposure and multidrug resistance.
As an alternative to cell specific cancer targeting strategies (which are often afflicted with the heterogeneity of cancer cells as with most biological systems), a novel polymeric micelle constitute of two block copolymers of poly(L-lactic acid)-b-poly(ethylene glycol)-b-poly(L-histidine)-TAT (transactivator of transcription) and poly(L-histidine)-b-poly(ethylene glycol) was developed. The mic...
متن کاملSodium cholate-enhanced polymeric micelle system for tumor-targeting delivery of paclitaxel
Purpose Polymeric micelles are attractive nanocarriers for tumor-targeted delivery of paclitaxel (PTX). High antitumor efficacy and low toxicity require that PTX mainly accumulated in tumors with little drug exposure to normal tissues. However, many PTX-loaded micelle formulations suffer from low stability, fast drug release, and lack of tumor-targeting capability in the circulation. To overcom...
