Polyene antifungals bind to ergosterol, the main sterol in the fungal cell membrane, and cause depolarization of the membrane. This increases the membrane permeability and leads to cell death. They are not absorbed when given orally, so are used to treat fungal infections of the gastrointestinal tract, such as oral thrush .

Polyene antimycotics, sometimes referred to as polyene antibiotics, are a class of antimicrobial polyene compounds that target fungi. [1] These polyene antimycotics are typically obtained from certain species of Streptomyces bacteria.

Polyenes are a class of broad spectrum antifungal compounds with a cyclic amphiphilic macrolide substructure which are derived from a species of Streptomyces bacteria. 11 The polyenes are antifungal by virtue of binding to ergosterol, which is a prevalent steroid in the fungal cell wall, resulting in depolarization of the membrane leading to inc...

2020年12月1日 · AmB is an old and most widely used polyene drug and has an irreplaceable role in cryptococcal meningitis treatment because of its high efficacy and low drug resistance. It is also used for treating aspergillosis and candidiasis.

In microbiology, polyenes are a type of antifungal medication. They work by binding to ergosterol, a component of the fungal cell membrane, creating pores that cause the cell to leak, eventually leading to the cell's death.

They are a reduced form of POLYYNES. A vitamin important for retinal function that is used clinically to correct vitamin A deficiency. An oral retinoid used in the treatment of severe psoriasis.
