Probing alamethicin channels with water-soluble polymers

Channel access resistance has been measured to estimate the characteristic size of a single ion channel. We compare channel conductance in the presence of nonpenetrating water-soluble polymers with that obtained for polymer-free electrolyte solution. The contribution of the access resistance to the total alamethicin channel resistance is 10% for first three open channel levels. The open alameth...

Phase behavior of temperature-responsive polymers with tunable LCST: An equation-of-state approach

The aqueous solution phase behavior of (ethylene oxide)/ethylene copolymers with varying degree of hydrophobicity is explored using an equation of state approach. The general formalism of the lattice-fluid with hydrogen-bonding theory is employed after a minor adjustment to account for multiple types of hydrogen bonds. The theoretical model is shown to be effective in describing the phase behav...

Water soluble polymers in tumor targeted delivery.

The rationales for the use of water soluble polymers for anticancer drug delivery include: the potential to overcome some forms of multidrug resistance, preferential accumulation in solid tumors due to enhanced permeability and retention (EPR) effect, biorecognizability, and targetability. The utility of a novel paradigm for the treatment of ovarian carcinoma in an experimental animal model, wh...

Hydration, phase separation and nonlinear rheology of temperature-sensitive water-soluble polymers.

The collapse of a poly(N-isopropylacrylamide) (PNIPAM) chain upon heating and the phase diagrams of aqueous PNIPAM solutions with a very flat lower critical solution temperature (LCST) phase separation line are theoretically studied on the basis of cooperative dehydration (simultaneous dissociation of bound water molecules in a group of correlated sequence), and compared with the experimental o...

The Effect of Water Soluble Polymers on Felodipine Aqueous Solubility and Complexing Abilities with Natural and Modified β-Cyclodextrin

       Purpose of this study was to investigate the effect of the presence of the water soluble polymers viz HPMC, PVP and PEG 6000 on aqueous solubility and complexation abilities of felodipine with or without presence of β-cyclodextrin (βCD) and HPβCD by phase solubility studies. The data revealed the initial increase in drug solubility followed by plateau in t...
