Abstract

The invention discloses tetrandrine derivatives and a preparation method thereof. The structural general formula of the compounds is as shown in the specification. The method comprises the following steps: dissolving bisbenzylisoquinoline compounds used as raw materials in a certain solvent, adding a reactant Y, mixing, reacting for 0.1-72 hours at a temperature ranging from minus 20 to 300 DEG C and under a neutral or alkaline condition, adding an acid to a solution obtained after reacting and neutralizing, and then carrying out separation and purification to obtain target products. The tetrandrine derivatives prepared by the method have an outstanding inhibition effect on the proliferation of the human hepatocarcinoma cell line HepG2 and the human colon cancer cells HT29, and thus can be applied to preparing anti-tumor medicines.

Description

technical field [0001] The invention relates to a novel tetrandrine derivative, its preparation method and its application in the preparation of antitumor drugs. Background technique [0002] Tetrandrine, also known as Tetrandrine or Tetrandrine, is a bisbenzylisoquinoline compound. It is mainly used clinically for rheumatic pain, arthralgia, neuralgia, and also for silicosis. Hanjisong (dimethyl iodide tetrandrine, the quaternary ammonium salt of tetrandrine) is a striated muscle relaxant, which can be used clinically to relax striated muscles during surgery. Experimental studies have proved that tetrandrine has certain effects on lung cancer, chronic myelogenous leukemia, liver cancer, neuroblastoma, breast cancer, etc., and its mechanism is related to the reversal of multidrug resistance, induction of apoptosis, radiosensitization, Inhibition of tumor angiogenesis. It has been proved by in vitro experiments (Xu Meng, et al. Experimental study on the reversal of chemothe...
