Preparation and in vivo pharmacokinetics of curcumin-loaded PCL-PEG-PCL triblock copolymeric nanoparticles
BACKGROUND Curcumin (CUR) has been linked with antioxidant, anti-inflammatory, antimicrobial, anti amyloid, and antitumor effects, but its application is limited because of its low aqueous solubility and poor oral bioavailability. METHODS To improve its bioavailability and water solubility, we synthesized two series of poly (ε-Caprolactone)-poly (ethylene glycol)-poly (ε-Caprolactone) tribloc...
متن کاملEstimation of the poly (ε-caprolactone) [PCL] and α-cyclodextrin [α-CD] stoichiometric ratios in their inclusion complexes [ICs], and evaluation of porosity and fiber alignment in PCL nanofibers containing these ICs
This paper describes the utilization of Proton-Nuclear Magnetic Resonance spectroscopy ((1)H NMR) to quantify the stoichiometric ratios between poly (ε-caprolactone) [PCL] and α-cyclodextrin (α-CD) present in their non-stoichiometric inclusion complexes [(n-s)-ICs]. This paper further describes the porosity and fiber alignment of PCL nanofibers nucleated by the [(n-s)-ICs] during electrospinnin...
متن کاملPreparation and evaluation of PCL-PEG-PCL micelles as potential nanocarriers for ocular delivery of dexamethasone
Objective(s): Micelles have been studied as nanoparticulate drug delivery systems for improving the topical ocular delivery of hydrophobic drugs. The objective of this study was to develop and characterize dexamethasone-loaded polycaprolactone-polyethylene glycol-polycaprolactone (PCL-PEG-PCL) micelles to improve patient compliance and enhance the ocular bioavailability of poorly water-soluble ...

متن کاملPreparation and Characterization of PCL-PEG-PCL Copolymeric Nanoparticles as Polymersomes for Delivery Hydrophilic Drugs
Background: A novel drug delivery system using poly (ε-caprolactone) - poly (ethylene glycol) -poly (ε-caprolactone) (PCL-PEG-PCL) was established in this study. Methods: Ceftriaxone (CTX) was encapsulated within PCL-PEG-PCL nanoparticles by a double emulsion technique (w/o/w), leading to creation of ceftriaxone-loaded PCL-PEG-PCL (CTX/PCL-PEG-PCL) polymersomes. The resulting polymersomes...
متن کاملPreparation and characterization of PCL-PEG-PCL polymersomes for delivery of clavulanic acid
The Clavulanic acid (CLV) is a suicide inhibitor of bacterial beta-lactamase enzymes from Streptomyces clavuligerus. In the present study, a reliable drug delivery system using poly (ε-caprolactone)-poly (ethylene glycol)-poly (ε-caprolactone) (PCL-PEG-PCL) was synthesized and the release profile of the CLV from the drug-loaded polymersomes was evaluated. In this study, CLV was encapsulated wit...
