Metabolite Identification
Common Name(R)-miconazole
Description(R)-miconazole is a member of the imidazole antifungal class, characterized by its chiral nature and specific stereochemistry. The chemical structure of (R)-miconazole features a 1-(2,4-dichlorobenzyl)-2-(1H-imidazol-1-yl)methanol framework, which is critical for its interaction with biological targets. This compound is primarily involved in inhibiting the enzyme lanosterol 14α-demethylase, a key player in the ergosterol biosynthetic pathway in fungi, thereby disrupting cell membrane integrity and function. Studies have shown that (-)-(R)-miconazole achieves higher plasma concentrations compared to its enantiomer (+)-(S)-miconazole, with a concentration ratio ranging from 1.3 to 1.7 (PMID:28852798 ). Furthermore, biological evaluations indicate that (R)-miconazole accounts for the majority of the antifungal activity observed in racemic miconazole against various microorganisms, highlighting its efficacy in combating fungal infections (PMID:21384803 ). The distinct pharmacokinetic and pharmacodynamic properties of (R)-miconazole underscore its significance in antifungal therapy.
