Abstract

The invention discloses a method for testing the content of tedizolid phosphate enantiomer through high performance liquid chromatography. The method comprises the following steps: (1) preparing a test solution, namely precisely weighing tedizolid phosphate, diluting with a mobile phase, and uniformly shaking so as to obtain the test solution; (2) preparing a control solution, namely precisely weighing the test solution, diluting with the mobile phase, and uniformly shaking so as to obtain the control solution; (3) testing the content, namely respectively injecting the control solution and thetest solution into a liquid chromatography meter, recording spectrums, and calculating the content of the tedizolid phosphate enantiomer by using a self-contrasted method, wherein the mobile phase ismethanol-acetonitrile-acetic acid-ammonium acetate. By selecting spectrum conditions, tedizolid phosphate and enantiomer impurities of the tedizolid phosphate can be simply, rapidly and accurately separated and detected, and controllable quality of tedizolid phosphate and a preparation of the tedizolid phosphate is achieved. Development of synthesis processes is instructed, and quality standard formulation of tedizolid phosphate raw material medicines can be facilitated.

Description

technical field [0001] The invention relates to a method for measuring the content of tedizolid phosphate enantiomers by high performance liquid chromatography, and belongs to the technical field of medicine. Background technique [0002] Tedizolid Phosphate is a new type of oxazolidinone antibiotic developed by Cubist Pharmaceuticals. Its chemical name is {(5R)-(3-{3-fluoro-4-[6-(2-methyl-2H- Tetrazol-5-yl)-pyridin-3-yl]phenyl}-2-oxooxazolidin-5-yl)}methyl phosphate. Approved by the FDA in 2014, it is clinically used to treat acute bacterial skin and skin structure infections. Tedizolid phosphate is a prodrug that can be rapidly converted into biologically active tedizolid by phosphatase in vivo, thereby inhibiting protein synthesis. Its mechanism of action is different from other antibiotics, and cross-resistance will not occur with other antibiotics. Clinically, it is mainly used for the treatment of acute bacterial skin and skin structures caused by Staphylococcus aur...
