Permeability coefficients (Pm) across planar egg lecithin/decane bilayers and bulk hydrocarbon/water partition coefficients (Kw→hc) have been measured for 24 solutes with molecular volumes, V, varying by a factor of 22 and Pm values varying by a factor of 107 to explore the chemical nature of the bilayer barrier and the effects of permeant size on permeability. A proper bulk solvent which correctly mimics the microenvironment of the barrier domain was sought. Changes in Pm/Kw→hc were then… Expand
Permeability of fluid-phase phospholipid bilayers: assessment and useful correlations for permeability screening and other applications.
TLDR
The results serve as a starting point for estimating passive permeability of cell membranes to nonionized solutes as a function of temperature and cholesterol content of the membrane. Expand
Phospholipid surface density determines the partitioning and permeability of acetic acid in DMPC:cholesterol bilayers
TLDR
The results suggest that dehydration, previously considered to be a dominant component, is a minor factor in determining Ea, and chain ordering is a major determinant for molecular partitioning and transport across lipid bilayers, regardless of whether it is varied by lipid composition or temperature. Expand
Independence of substituent contributions to the transport of small-molecule permeants in lipid bilayer
TLDR
Functional group contributions to transport across egg lecithin bilayers appear to be independent of the compound to which they are attached, even though the thickness of the barrier domain in lipid bilayers is approximately the same as the extended length of the permeant. Expand
Structural Determinants of Water Permeability through the Lipid Membrane
TLDR
It is found that water permeability correlates most strongly with the area/lipid and is poorly correlated with bilayer thickness and other previously determined structural and mechanical properties of these single component bilayers. Expand
Local partition coefficients govern solute permeability of cholesterol-containing membranes.
TLDR
The simulations indicate that cholesterol does not affect the diffusion constant inside the membrane, and local partition coefficients at the lipid headgroups and at the cholesterol tails are modulated oppositely by cholesterol, explaining the experimental findings. Expand
Structural Determinants of Drug Partitioning in n-Hexadecane/Water System
TLDR
Observations indicate that the headgroups stratum, albeit well hydrated, does not have solvation characteristics similar to water and is also poorly described by the O/W partition characteristics. Expand

TLDR
A mathematical model is developed that can predict skin permeability to small (MW < 500 Da), hydrophobic solutes based on the fundamental transport properties of skin lipid bilayers and molecular properties of the solute. Expand
Permeability of drugs and hormones through a lipid bilayer: insights from dual-resolution molecular dynamics†
The unassisted permeation process of β-blocker drugs (alprenolol, atenolol, pindolol) and steroid hormones (progesterone, testosterone) through a lipid membrane is simulated by a novelExpand
Simple Predictive Models of Passive Membrane Permeability Incorporating Size-Dependent Membrane-Water Partition
TLDR
Investigation of the relationship between passive permeability and molecular size, in the context of solubility-diffusion theory, using a diverse compound set with molecular weights, suggests that these measurements are not size selective, a possible reason for their sometimes weak correlation with cell-based permeability.

Transport methods for probing the barrier domain of lipid bilayer membranes.
TLDR
The permeability of acetamide was found to be independent of bilayer thickness, suggesting that the barrier region of the bilayer does not resemble the hydrogen-bonding environment found in octanol, but is somewhat less selective than a hydrocarbon solvent. Expand
Monocarboxylic acid permeation through lipid bilayer membranes
TLDR
The exceptionally high permeability of formic acid and the high correlation of the other permeabilities to the hexadecane/water partition coefficient is a pattern that conforms with other nonelectrolyte permeabilities through bilayers, similar to other homologous solutes in other membrane systems. Expand
Permeability of small nonelectrolytes through lipid bilayer membranes
TLDR
Diffusion of small nonelectrolytes through planar lipid bilayer membranes was examined by correlating the permeability coefficients of 22 solutes with their partition coefficients between water and four organic solvents, and the molecular volume dependence of solute permeability suggests that the membrane barrier behaves more like a polymer than a liquid hydrocarbon.

Diffusion of lonizable Solutes Across Planar Lipid Bilayer Membranes: Boundary-Layer pH Gradients and the Effect of Buffers
TLDR
A theoretical model has been developed to describe the diffusion of both permeant and buffer species and predicted that membrane-permeable buffers significantly reduce boundary layer pH gradients through a feedback effect due to buffer cotransport. Expand

TLDR
The premeabilities of planar lipid bilayer membranes to butyric and formic acids were measured by tracer and pH electrode techniques to establish criteria for the applicability of each method and to resolve a discrepancy between previously published permeabilities determined using the different techniques.

TLDR
The general conclusion of this study is that H2O and nonelectrolytes cross lipid bilayer membranes by a solubility- diffusion mechanism, and that the bilayer interior is much more like an oil than a rubber-like polymer. Expand
Solute structure-permeability relationships in human stratum corneum.
TLDR
Although uptake into human stratum corneum was relatively insensitive to solute lipophilicity, reflecting the predominant role of proteins in the uptake, permeability coefficients were found to be more sensitive to lipophilicities, suggesting that transport is by a lipid pathway. Expand

Lipid composition and permeability of liposomes.
TLDR
Comparisons of the permeability of the liposomes of phospholipids with asymmetric chains are much more permeable than those of lecithins with chains of equal length but with the same total number of paraffin carbon atoms suggests that, certainly at lower temperatures, the model structures are muchMore permeable.

TLDR
The ability to form bilayers essentially free of the solvent used in the forming solution makes it possible to determine the area per molecule of the surface active lipid in the bilayer. Expand
