Bioactivity Comments
In fungi and yeast the molecular target of tioconazole is the cytochrome P450 enzyme lanosterol 14-α demethylase (CYP51 or ERG11) which converts lanosterol to the crucial cell wall component ergosterol. Without ergosterol the pathogens are unable to survive. Tioconazole also inhibits activity of the human P450 enzyme CYP8B1 that participates in a branch of the bile acid biosynthesis pathway [2].
