Studies on modified chitosan membranes. II. Dialysis of low molecular weight metabolites

Abstract

SYNOPSISThe permeabilities of low molecular weight metabolites were determined through chitosan and a series of chitosan-poly (vinyl pyrrolidone) ( P V P ) membranes. The dialysis studies were carried out in uitro using a diaphragm-type test cell. The basic metabolites (urea, creatinine, and glucose) show higher permeation rates than do the acidic metabolites (uric acid and phosphate) through all the modified membranes. The hydrophilicity of the membranes, molecular weight, and chemical nature of the metabolites were important parameters in determining transport properties of the membranes. It was observed that higher permeation rates can be obtained by manipulating the amount of PVP in the blended membranes. The PVP weight loss in the aqueous medium was negligible.

Paclitaxel‐Loaded β‐Cyclodextrin‐Modified Poly(Acrylic Acid) Nanoparticles through Multivalent Inclusion for Anticancer Therapy

“…Since the hydrophobic interior of β ‐CD can encapsulate PTX molecules and significantly enhance the solubility of PTX in water through host–guest interactions and maintain its biological activity in vitro, the influence of β ‐CD on the solubility of PTX was studied, and a series of feeding molar ratios of β ‐CD to PTX were used to measure the PTX solubility and loading efficiency (Figure ). Compared to the very low aqueous solubility (0.34 μg mL −1 ) of pure PTX, its solubitity could be greatly increased to 36.02 μg mL −1 through the formation of multivalent inclusion complexes with PCDAA, which was over 100 times than that of pure PTX, suggesting the great enhancement of PTX solubility.…”

Biomedical-Grade Chitosan in Wound Management and Its Biocompatibility In Vitro

“…Therefore, several chemically modified chitosan derivatives have been synthesized and examined to improve solubility and versatility (Jayakumar et al, 2005;Prabaharan & Mano, 2007). Chemically modified chitosan structures may result in improved solubility in general organic solvents (Qurashi et al, 1992). For example, phosphorylated chitosan is a water-soluble derivative of chitosan, which is potentially important for drug delivery systems.…”

Miscible chitosan/tertiary amide polymer blends

“…It is therefore likely that PVP may also interact with the hydroxyl and amino groups of chitosan to achieve miscibility. Qurashi et al 18,19 used chitosan/PVP blends as membranes for dialysis. They reported that the membranes were transparent and there was no separation of PVP at any temperature based on differential scan-ning calorimetric (DSC) measurements.…”
