General description

Chemical structure: imidazole

Application

Ketoconazole is a broad spectrum antifungal agent used to treat candidiasis, chronic mucocutaneous candidiasis, oral thrush, candiduria, blastomycosis, coccidioidomycosis, histoplasmosis, chromomycosis, and paracoccidioidomycosis. It is used to identify p-glycoprotein/CYP3A-limited bioavailability in the monkey model[1], to study interleukin 1 mediated antitumor effects[2], and drug interactions in vivo[3]
CYP3A4 inhibitor

Biochem/physiol Actions

Ketoconazole interacts with 14-α demethylase, a cytochrome P-450 enzyme that is necessary for the conversion of lanosterol to ergosterol. This interaction inhibits ergosterol synthesis and results in increased fungal cellular permeability. Other possible mechanisms of action are the inhibition of endogenous respiration, interaction with membrane phospholipids, inhibition of yeast transformation to mycelial forms, inhibition of purine uptake, and impairment of triglyceride and/or phospholipid biosynthesis. Ketoconazole inhibits the synthesis of thromboxane and sterols such as aldosterone, cortisol, and testosterone .

Zanthoxylum chiloperone var. angustifolium was investigated. Alkaloids 1-3 from the canthin-6-one series were characterized. Derivatives 7-28 were prepared by hemisynthesis or total synthesis. All compounds were tested for in vitro antifungal activities against five pathogenic fungal strains. Analogues of canthin-6-one

Biotransformation of the tricyclic antidepressant desipramine (DMI) to its metabolite 2-hydroxy-desipramine (2-OH-DMI) was studied in vitro using microsomal preparations from human, monkey, mouse and rat liver. In all species 2-OH-DMI was the principal identified metabolite. Mean (+/- S.E.) reaction parameters
