Penetration of Lipid Monolayers by Polyene Antibiotics CORRELATIOS WITH SELECTIVE TOXICITY AND MODE OF ACTION*
Previous studies have shown that polyene antibiotics alter permeability in sensitive fungi and thus lead to the loss of essential cytoplasmic constituents, which ultimately culminates in cell death (l-3). Subsequent investigations have led to the contention that the selective toxicity of the polyene antibiotics is due to interaction with a component present only in the membrane of sensitive org...

متن کاملLateral pressure profiles in lipid monolayers.
We have used molecular dynamics simulations with coarse-grained and atomistic models to study the lateral pressure profiles in lipid monolayers. We first consider simple oillair and oil/water interfaces, and then proceed to lipid monolayers at air/water and oil/water interfaces. The results are qualitatively similar in both atomistic and coarse-grained models. The lateral pressure profile in a ...
متن کاملLateral tensions and pressures in membranes and lipid monolayers.
The effects of lateral tension on the properties of membranes are often explained in comparison with analogous experiments on monolayers, which yield more detailed data. To calculate the effects of changes in tension on the composition of, or incorporation of amphiphiles into membranes we examine (i) the fidelity of the monolayer analogy, (ii) the range of possible tensions in a membrane, and t...
متن کاملCritical and off-critical miscibility transitions in model extracellular and cytoplasmic myelin lipid monolayers.
Monolayers based on the composition of the cytoplasmic (CYT) or extracellular (EXT) sides of the myelin bilayer form coexisting immiscible liquid phases similar to the liquid-ordered/liquid-disordered phases in phospholipid/cholesterol monolayers. Increasing the temperature or surface pressure causes the two liquid phases to mix, although in significantly different fashion for the CYT and EXT m...
