Isoconazole nitrate also exerts several other effects on the fungal membrane, which are independent of inhibition of the ergosterol synthesis. Isoconazole nitrate (ISN) causes a rapid reduction of cellular adenosine triphosphate (ATP) within 10 min of in vitro exposure.
Isoconazole nitrate (1, 10 μg/mL) induces a blockade of cell division in vitro by its action on synthesis and organisation of the cell membrane. Isoconazole nitrate (50, 100 μg/mL), ISN induced necrosis and death of fungal cells.
