In order to apply curcumin as a photosensitizer in photodynamic therapy (PDT) one needs a formulation that can solubilize and stabilize the compound. Pluronics® (Pluronic) are reported to both solubilize and stabilize curcumin against hydrolytic degradation. The aim of the present work was therefore to investigate the influence of Pluronic formulation on the photocytotoxicity of curcumin. Inter...
Colonization of roots by Pseudomonas chlororaphis O6 (PcO6) involves root surface coverage through surface motility and biofilm formation. Root colonization and the production of antifungal phenazines are important in the ability of the bacterium to protect plants against pathogens. In this in vitro study we report that both biofilm formation and phenazine production are differentially influenc...
Multidrug resistance (MDR) remains one of the biggest obstacles for effective cancer therapy. Currently there are only few methods that are available clinically that are used to bypass MDR with very limited success. In this review we describe how MDR can be overcome by a simple yet effective approach of using amphiphilic block copolymers. Triblock copolymers of poly(ethylene oxide) (PEO) and po...
Pluronic block copolymer P85 was shown to inhibit the P-glycoprotein (Pgp) drug efflux system and to increase the permeability of a broad spectrum of drugs in the blood-brain barrier (BBB). However, there is an entire series of Pluronics varying in lengths of propylene oxide and ethylene oxide and overall lipophilicity. This study identifies those structural characteristics of Pluronics require...
The surface of nanoparticles is often functionalised with polymeric surfactants, in order to increase systemic circulation time. This has been investigated mainly for intravenously administered nanoparticles. This study aims to elucidate the effect of surface coating with various concentrations of polymeric surfactants (PEG and Pluronics F127) on the in vitro protein binding as well as the tiss...
Pluronic/bile salt/phospholipid mixed micelles (Pluronic/BS/PS-MM) drug carrier system for solubilization hydrophobic drugs was developed. A typical hydrophobic compound, pyrene, was selected as a representative hydrophobic compound to model the hydrophobic drugs. Five Pluronics, F68, F88, F98, F108, and F127 with different PPO chain length were studied. CMC data and solubilization capacities w...
A simple approach to enhancing the activity and stability of organophosphorus hydrolase (OPH) is developed based on interactions between the hydrophobic poly(propylene oxide) (PPO) block of amphiphilic Pluronics and the enzyme. This strategy provides an efficient route to new formulations for decontaminating organophosphate neurotoxins.
