The pyrimidine thiol acetamide ramification is a compound with a structure as shown in a general formula I or I' and pharmaceutically acceptable salt, ester or a prodrug thereof. The invention also provides a preparation method of the compound and application of a composition which contains one or more compounds in a medicament for curing and preventing HIV (Human Immunodeficiency Virus) injection. The general formula I is as shown the specification.

Description

technical field [0001] The invention relates to a derivative and its preparation method and application, in particular to pyrimidine thioacetamide derivatives and its preparation method and application, belonging to the technical field of medicine. Background technique [0002] Human immunodeficiency virus (HIV) is the pathogen that causes acquired immunodeficiency syndrome (AIDS, AIDS). In the HIV replication cycle, reverse transcriptase (reverse transcriptase, RT) plays a crucial role, responsible for the completion of RNA-directed DNA synthesis, RNA hydrolysis and DNA-directed DNA synthesis and other key links. Therefore, using RT as a target for drug design has the advantages of high inhibitory activity, good selectivity, and less toxic and side effects, and is an important strategy for the development of anti-HIV / AIDS drugs. According to the difference in chemical structure and interaction mechanism with enzymes, HIV reverse transcriptase inhibitors can be mainly divid...
