产品描述:
Efinaconazole-d4 is intended for use as an internal standard for the quantification of efinaconazole (Item No. 23839) by GC- or LC-MS. Efinaconazole is a broad-spectrum triazole antifungal agent with activity against Acremonium, Aspergillus, Candida, Cryptococcus, Epidermophyton, Fusarium, Microsporum, Paecilomyces, Pseudallescheria, Scopulariopsis, Trichophyton, and Trichosporon.{41490} It inhibits the growth of T. rubrum and T. mentagrophytes clinical isolates with MIC values ranging from ≤2.0 to 60 ng/ml and of C. albicans isolates with MIC values ranging from ≤0.5 to >250 ng/ml. Efinaconazole inhibits sterol 14α-demethylase, which arrests ergosterol (Item No. 19850) biosynthesis at the fungal membrane.{41491} It inhibits ergosterol biosynthesis in T. mentagrophytes and C. albicans with IC50 values of 7.0 and 0.40 ng/ml, respectfully. Topical formulations containing efinaconazole have been used for the treatment of onychomycosis.
