Tetrandrine BiologicalActivity
| Description | Tetrandrine is a bis-benzyl-isoquinoline alkaloid, which inhibits voltage-gated Ca2+ current (ICa) and Ca2+-activated K+ current. |

| In Vitro | The effects of Tetrandrine, a bis-benzyl-isoquinoline alkaloid, on voltage-gated Ca2+ currents (ICa) and on Ca2+-activated K+ current (IK(Ca)) and channels in isolated nerve terminals of the rat neurohypophysis are investigated using patch-clamp techniques. The non-inactivating component of ICa is inhibited by external Tetrandrine in a voltage- and dose-dependent manner, with an IC50=10.1μM. Tetrandrine decreases the channel-open probability, within bursts, with an IC50=0.21 μM[1]. To evaluate the effects of Tetrandrine on HCC cells, Huh7, HCCLM9 and Hep3B cells are treated with 0 (DMSO), 0.5, 1, 2 or 4 μM of Tetrandrine for 24 h. The cell proliferation assay indicates that Tetrandrine exhibits almost no effect on the inhibition of HCC cell proliferation at 0.5-2 μM. However, Tetrandrine inhibits HCC cell migration in a dose-dependent manner. Furthermore, a wound-healing and transwell assay shows that 2 μM Tetrandrine significantly inhibits HCC cell migration and invasion[2]. |
| In Vivo | To evaluate the effect of Tetrandrine on the inhibition of tumor metastasis in vivo, HCCLM9 subcutaneous tumor xenograft models is established with athymic nude mice. When the tumor volume reach approximately 50 mm3, nude mice are orally administered vehicle or Tetrandrine (30 mg/kg) every other day for 37 days. Tetrandrine treatment inhibits tumor growth by reducing the tumor volume and weight[2]. |
| Cell Assay | Huh7, HCCLM9 and Hep3B cells are seeded in a 96-well plate at a cell density of 5 × 103 cells/well. The cells are treated with the indicated concentrations (0-4 μM) of Tetrandrine for 24 h. The cells are subsequently stained with 20 μL of MTS for 1-2 h, and the plates are read at 490 nm on a BioTek ELx800[2]. |
| Animal Admin | Mice[2] Four-week-old male athymic BALB/c nu/nu SPF mice (body weight range from 18 g to 20 g) are used. HCCLM9 WT and HCCLM9 ATG7 KO cells (5 million) resuspended in 0.2 mL of PBS are subcutaneously implanted into the right flank of each mouse. When the tumor volume reach approximately 50 mm3, the tumor-bearing mice are randomly divided into control and treatment groups (n = 6). The control and treatment groups are administered oral injection of vehicle (0.5% methylcellulose) and Tetrandrine at 30 mg/kg of body weight every other day for 37 days. During the treatment, the tumor volumes are measured every day and are calculated. |
