Biological Activity

[Description]:

Efinaconazole(KP-103) is a novel triazole antifungal drug currently under development as a topical treatment for onychomycosis.IC50 value: 0.0039 ug/ml (MIC for T. mentagrophytes SM-110) [1]Target: antifungal agentin vitro: Efinaconazole was 4-fold more active than itraconazole against T. mentagrophytes SM-110 (MICs of 0.0039 and 0.016 μg/ml, respectively). Similarly, efinaconazole was 8-fold more active than clotrimazole against C. albicans ATCC 10231 (MICs of 0.00098 and 0.0078 μg/ml, respectively) [1]. In a comprehensive survey of 1,493 isolates, efinaconazole MICs against T. rubrum and T. mentagrophytes ranged from ≤ 0.002 to 0.06 μg/ml, with 90% of isolates inhibited (MIC90) at 0.008 and 0.015 μg/ml, respectively. Efinaconazole MICs against 105 C. albicans isolates ranged from ≤ 0.0005 to >0.25 μg/ml, with 50% of isolates inhibited (MIC50) by 0.001 and 0.004 μg/ml at 24 and 48 h, respectively [2].in vivo: The therapeutic efficacy of KP-103, a triazole derivative, for 10 guinea pigs with interdigital tinea pedis or tinea corporis was investigated. Topical KP-103 solution (0.25 to 1%) was dose-dependently effective in treating both dermatophytoses. A 1% KP-103-treatment rendered all infected skins culture-negative on day-2 posttreatment [3].
