Terbinafine (TDT 067) is a novel allylamine antifungal agent and a potent noncompetitive squalene cyclooxygenase inhibitor (Ki value is 30 nM) that selectively inhibits squalene cyclooxygenase, leading to a decrease in ergosterol, which interferes with membrane function and cell growth[1-2].
Terbinafine stimulates ROS production in HaCaT cells and induces a HaCaT Cytotoxic response with IC50 values of 12.5-25 μg/mL, and the Terbinafine group exhibited moderate cell rounding and cell shrinkage compared to untreated control and vector control[3]. Terbinafine (0, 30, 60 and 120 μM) concentration-dependently increased the activity of the p21 promoter in HUVEC and induced HUVEC cell cycle arrest by upregulating the p21 protein[4].
Terbinafine showed good antifungal activity against cutaneous fungal disease in guinea pigs caused by Trichophyton mentagrophytes or Microsporum canis[5]. After oral administration of Terbinafine at a dose of 30 mg/kg, the maximum plasma levels in cats, greyhounds and red-tailed eagles were 3.22, 4.01 and 1.2 μg/ml, respectively. The differences in the half-life of Terbinafine were not significant in cats (8.01 h), greyhounds (8.6 h), and horses (8.1 h), whereas it was significantly prolonged in the red-tailed eagles (17.5 h) and the African penguins ( 17.0 h) were significantly prolonged[2].

| Cell experiment [1]: | |
Cell lines | HaCaT cells |
Preparation Method | Terbinafine was incubated with HaCaT cells for 24 hours, and DMSO (1%) and doxorubicin were used as control and positive control, respectively. Sulforhodamine B protein (SRB) staining was used to evaluate the cytotoxicity of Terbinafine on HaCaT cells. |
Reaction Conditions | 50、25、12.5、6.25、3.125 and 1.56 μg/mL, 24 h |
Applications | The IC50 value of Terbinafine against HaCaT cells was 12.5-25 μg/mL. IC50 values of Terbinafine showed moderate degree of cell rounding and cell shrinkage compared with untreated and vehicle controls. |
| Animal experiment [2]: | |
Animal models | Guinea Pig Model of Skin Infection |
Preparation Method | For treatment, Terbinafine is suspended in 2% methylcellulose and 0.5% Tween 80. Treatment began on the day of inoculation with Trichophyton mentagrophytes and continued once daily for 9 consecutive days. Mycologic status was assessed 24 hours after the last treatment. |
Dosage form | 2, 4, 6 and 8 mg/kg/day, oral, 9 days |
Applications | Oral dose of 4 to 6 mg/kg per day from the day of infection for good activity against Trichophytsis for 9 consecutive days. |

| General tips | Please select the appropriate solvent to prepare the stock solution according to the
solubility of the product in different solvents; once the solution is prepared, please store it in
separate packages to avoid product failure caused by repeated freezing and thawing.Storage method
and period of the stock solution: When stored at -80°C, please use it within 6 months; when stored
at -20°C, please use it within 1 month. To increase solubility, heat the tube to 37°C and then oscillate in an ultrasonic bath for some time. |
