| Name | Tetrandrine |
| Description | Tetrandrine (Sinomenine A) is a naturally occurring biphenylisoquinoline alkaloid, a calcium channel inhibitor. Tetrandrine inhibits voltage-gated calcium channels (ICa) and Ca2+-activated potassium channels. |
| In vitro | METHODS: Leukemia cell lines K562, THP-1, U937, and HL60 were treated with Tetrandrine (1-3 µM) for 24-72 h, and cell numbers were measured.
RESULTS: 2 µM and 3 µM Tetrandrine significantly inhibited cell proliferation. [1]
METHODS: A panel of GFP-LC3-expressing tumor cell lines MCF-7, PLC-5, SK-Hep1, HeLa, and PC3 cells were treated with Tetrandrine (5 µM) for 16 h and GFP-LC3 spots were detected.
RESULTS: Tetrandrine significantly induced GFP-LC3 spot formation with similar potency (5 µM) in all cell lines tested.Tetrandrine induced autophagy in multiple cell lines. [2] |
| In vivo | METHODS: To detect anti-tumor activity in vivo, athymic nude mice bearing THP-1 xenografts were administered Tetrandrine (25-50 mg/kg, 0.5% methylcellulose) by gavage once daily for 13 days.
RESULTS: Tetrandrine treatment reduced tumor growth. [1] |
