Membrane Transport Inhibition as Mode of Action of Polyene Antimycotics: Recent Data Supported by Old Ones
نویسندگان
چکیده
Recent studies demonstrate that the actual interactions of polyenes with membrane sterols are the basis for their antimycotic toxicity and not, as previously assumed, their potential to form pores. Therefore, sterols must play a vital role in membranes and this function is seriously disturbed once polyenes bind to and/or sequester them. Essential membrane proteins obviously require sterols for their activity. Among the various membrane protein/ergosterol interactions discussed herein, transport proteins of the plasma membrane are most likely the primary target for polyenes. All data available which support this notion are summarized in this review. Even data obtained almost 40 years ago could be useful in guiding future research.

Polyene antibiotic that inhibits membrane transport proteins.
The limited therapeutic arsenal and the increase in reports of fungal resistance to multiple antifungal agents have made fungal infections a major therapeutic challenge. The polyene antibiotics are the only group of antifungal antibiotics that directly target the plasma membrane via a specific interaction with the main fungal sterol, ergosterol, often resulting in membrane permeabilization. In ...

This article evaluates the effect of membrane active channel-forming polyene antibiotic (PA) of levorin and its alkyl derivatives on the muscle performance. The membrane channels of muscle cells are capable to transport ions of potassium, sodium, and calcium. In the period of an intensive muscle exercise, the necessity for organic substrates increases and these channels start to work with the g...

متن کاملEffect of Complexation Reaction Constant on the Separation of Propylene/Propane by Supported Liquid Membrane
Traditional systems for olefin/paraffin separation, like low-temperature distillation, are expensive and very energy consuming, and therefore, alternative separation methods are desired. Facilitated transport membranes are new tools for this separation to be substituted in large scale separation of olefin-paraffin mixtures. To design a membrane process for olefin-paraffin separation, equilibriu...
