What antifungal inhibits squalene epoxidase?
allylamines terbinafine
Antifungal Agents The allylamines terbinafine and naftifine act by inhibiting squalene epoxidase, an enzyme in the pathway leading to the synthesis of ergosterol in the fungal cell membrane.
What is squalene in fungi?
Squalene is an ancient molecule. In plants, squalene is the precursor to stigmasterol. In certain fungi, it is the precursor to ergosterol.
Is squalene toxic to fungi?
Terbinafine is a selective inhibitor of fungal squalene epoxidase, thereby increasing the extracellular concentration of squalene to levels toxic to fungal cells and inhibiting cell wall function because of decreased synthesis of ergosterol.
How Lanosterol is formed from squalene?
The first recognizable steroid ring system is lanosterol; it is formed first by the epoxidation of the double bond of squalene that was originally derived from a DMAPP through farnesyl pyrophosphate, and then by the cyclization of squalene epoxide.
What is Lanosterol made from?
Lanosterol is a natural product found in Eleutherococcus sessiliflorus, Euphorbia mellifera, and other organisms with data available. A triterpene that derives from the chair-boat-chair-boat folding of 2,3-oxidosqualene. It is metabolized to CHOLESTEROL and CUCURBITACINS.
