Abstract

The invention discloses a method for detecting the content of optical isomers of bortezomib. The method is a high-performance liquid chromatography and comprises the steps as follows: a normal-phase chromatographic column with an amylase tris(3,5-dimethylphen-ylcarbamate) chiral stationary phase serving as a filler is adopted for coating the surface of silica gel, a mixed solvent of n-hexane, alcohol and an organic amine polarity modifier serves as a mobile phase, wherein the volume ratio of the n-hexane, the alcohol and the organic amine polarity modifier is (97-95):(3-5):(0-0.5), an ultraviolet detector is used for detection, the flow velocity is in a range of 1.0-1.4ml / min, and the temperature of the chromatographic column is in a range of 25-45 DEG C. According to the method, four optical isomers of the bortezomib can be well separated, so that the content of each optical isomer in the bortezomib can be measured accurately. The method is stable, reliable, high in sensitivity and applicable to quality control of bortezomib active ingredients and preparations of the bortezomib active ingredients in the research and production processes.

Description

technical field [0001] The invention relates to a method for detecting the content of bortezomib optical isomers, belonging to the field of drug analysis. Background technique [0002] Bortezomib (bortezomib) is a new type of anti-tumor drug developed by Millennium Corporation of the United States, and its trade name is Velcade. It is the first proteasome inhibitor to enter clinical application. Both the U.S. Food and Drug Administration and the European Agency for Drug Evaluation have approved Velcade for the clinical treatment of multiple myeloma. [0003] Bortezomib reversibly inhibits the chymotrypsin / trypsin activity of protease 26S subunit in mammalian cells by selectively binding to threonine in the proteasome active site, thereby inhibiting the expression of genes related to cell proliferation, Reduce the secretion of myeloma cell growth factors and the expression of adhesion factors, eventually leading to tumor cell apoptosis. Clinical studies have confirmed that ...
