(Rac)-Ketoconazole ((Rac)-R 41400) is an antifungal imidazole compound with oral activity. (Rac)-Ketoconazole interferes with ergosterol synthesis by inhibiting cytochrome P450-dependent 14α-sterol demethylase (CYP51), a key enzyme on the fungal cell membrane, leading to membrane dysfunction and ultimately inhibition of fungal growth and reproduction. (Rac)-Ketoconazole is indicated for studies of fungal infections[1].

ChEBI: 1-acetyl-4-(4-{[2-(2,4-dichlorophenyl)-2-(1H-imidazol-1-ylmethyl)-1,3-dioxolan-4-yl]methoxy}phenyl)piperazine is a dioxolane that is 1,3-dioxolane which is substituted at positions 2, 2, and 4 by imidazol-1-ylmethyl, 2,4-dichlorophenyl, and [para-(4-acetylpiperazin-1-yl)phenoxy]methyl groups, respectively. It is an ether, a member of imidazoles, a N-arylpiperazine, a dioxolane, a dichlorobenzene and a N-acylpiperazine.
