Terbinafine-d₃is intended for use as an internal standard for the quantification of terbinafine by GC- or LC-MS. Terbinafine is a broad-spectrum antifungal agent that has activity againstT. rubrum,T. mentagrophytes,T. verrucosum,E. floccosum,M. canis,A. fumigatus, andS. schenckii(MIC₅₀s = 0.003-0.8 μg/ml).¹It selectively inhibitsC. albicanssqualene epoxidase over rat liver epoxidase (IC₅₀s = 0.03 and 77 μM, respectively).²Terbinafine (90-120 µM) induces cell cycle arrest at the G₀/G₁phase in COLO 205 tumor cells and human umbilical vein endothelial cells (HUVECs).^3,4Formulations containing terbinafine have been used in the treatment of nail and skin fungal infections.
