Tetrandrine, isolated from the root of Stephania tetrandra S Moore, is a traditional Chinese clinical agent for silicosis, autoimmune disorders, inflammatory pulmonary diseases, cardiovascular diseases and hypertension. Tetrandrine is a potent MDR-reversing agent and is an ABCB1/ABCC1 inhibitor. Tetrandrine (CBT-1) is being developed by CBA Pharma, as an adjunctive therapy to chemotherapy in various cancer types with multiple drug resistance (MDR), including acute myelogenous leukemia , Breast, Non-Hodgkin’s Lymphoma, Hodgkin’s disease, Non-Small Cell Lung Cancer, Multiple Myeloma, Gallbladder, Pancreatic, Gastrointestinal Tract, Small Cell Lung Cancer, Bladder, Head & Neck, and Sarcoma.

Route of Administration:
Oral
It was investigated the effect of combined treatment of irradiation and maximum non-cytotoxic doses of tetrandrine on the nasopharyngeal carcinoma cell lines CNE1 and CNE2. The maximum non-cytotoxic doses of tetrandrine in CNE1 and CNE2 cells were assessed using the MTT (3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide) assay. The maximum non-cytotoxic doses of tetrandrine in CNE1 and CNE2 cells were 1.5 μmol/L and 1.8 μmol/L, respectively. When cells were exposed to irradiation and the maximum non-cytotoxic doses of tetrandrine, the survival fraction was decreased.
