Problems solved by technology

[0006] In the long-term research and development process, the inventors of the present application found that in the process of preparing abacavir (VI), due to the relationship of chemical reaction balance, there is always a small amount of raw material residues, which are brought into the subsequent reaction steps and will interact with The raw materials or products in the follow-up reaction react, so many impurities are produced in the process of synthesizing abacavir, which will affect the purity of abacavir products. At present, some impurities have been disclosed, and there are related detection and control methods , and some impurities have not been disclosed, and there is no good method to detect and control these impurities, so there is an urgent need for a scientific and effective analysis method to detect and control impurities

Description

technical field [0001] The application relates to the technical field of drug analysis, in particular to a high-performance liquid phase detection method for impurities of abacavir. Background technique [0002] Abacavir (ABC) is a new anti-AIDS drug. It is a new carbocyclic 2'-deoxyguanosine nucleoside drug. It has high oral bioavailability and easily penetrates into the central nervous system. Like other nucleoside reverse transcriptase inhibitors, it is an inactive prodrug that is metabolized into an active triphosphate through four steps in the body, and inhibits human immunodeficiency virus (HIV) through the following two pathways: ) The role of reverse transcriptase: ① Competitively inhibit 2'-deoxyguanosine triphosphate (dGTP) (one of the DNA synthesis fragments) from incorporation into the nucleic acid chain. ② Effectively terminate DNA chain synthesis by preventing the addition of new bases. The chemical structural formula of abacavir is as follows: [0003] ...
