Abstract

The invention discloses a nucleotide analogue and a synthesis and a application thereof. The constitutional formula of the nucleotide analogue is that: Tetra-O-Acetyl-D-Ribose is adopted as a raw material and generates the nucleotide analogue containing a triazole ring formwork through four steps of reaction, wherein R is C2-C15 saturated or unsaturated alkyl, or C2-C10 saturated or unsaturated alkyl containing hetero atoms; or R is R1 which is hydroxyl, alkoxy, amino or substituent amido; or R is R2 which is aryl or saturated or unsaturated alkyl; or R is R3 which is halogen, amono, methoxyl, methyl or other substituent. The nucleotide analogue can restrain the growth of microorganism such as escherichia coli, and can be used as an inhibitor of dehydrogenase such as malate dehydrogenase.

Description

technical field [0001] The invention relates to a synthesis method of a class of nucleotide analogs, in particular to a synthesis method and application of a class of nucleotide analogs with a triazole ring structure, belonging to the field of chemical synthesis of organic compounds. Background technique [0002] Nucleoside and nucleotide analogues are used for the treatment of AIDS, hepatitis B virus, cancer, etc. et al. Chemical Reviews 2010, 110, 1828-1856) important drug. Among them, the base is a five-membered heterocyclic nucleoside with a triazole ring skeleton, which has the characteristics of simple synthesis and high biological activity. People have carried out more chemical synthesis and activity research on it (C.Najera et al.Organic & Biomolecular Chemistry 2009, 7 , 4567-4581). [0003] Under physiological conditions, nucleoside analogs must be converted into corresponding nucleotides in the cell, and then nucleoside triphosphates can be generated by nucleoti...
