Embodiment 1

[0025] Example 1 : 5-ethyl-6-cyclohexylmethyl-2-[(4-benzoyloxy)phenylcarbonylmethylthio]pyrimidine-4(3 H )-ketone synthesis, concrete operation is as follows:

[0026] Dissolve 3 mmol of 5-ethyl-6-(cyclohexylmethyl)-2-thiouracil in 10 ml of dry N,N -Dimethylformamide solution, add K 2 CO 3 (3 mmol), stirred at room temperature for 0.5 hours, added α-bromo-4-benzoyloxyacetophenone (3.3 mmol), continued to stir at 40°C, TLC traced the disappearance of the raw material point for about 18 hours, and stopped the reaction , pour the reaction solution into 50 ml of ice water, stir to precipitate the precipitate, filter, wash the precipitate with water, suction filter and dry at 70°C to obtain the crude product, which is subjected to column chromatography (petroleum ether: ethyl acetate = 2:1) , to obtain white crystal 1a, the detection results are as follows:

[0027] 1a

Abstract

The invention discloses 2-(4-alkylformyloxyphenylcarbonylmethylthio)pyrimidine compounds shown as a general formula I, pharmaceutically acceptable salts or N-oxides thereof, or N-oxides of the salts, or pharmaceutically acceptable prodrugs of the compounds. The compounds have high activity of resisting HIV-1 virus, low toxicity and high selectivity index and can be applied to preparing related medicines for treating and preventing Aids.

Description

technical field [0001] The invention belongs to the technical field of medicines, and in particular relates to a class of 2-(4-hydrocarbylformyloxyphenylcarbonylmethylthio)pyrimidinone compounds, which have good anti-HIV-1 virus activity and low toxicity , high selectivity index, can be used in the treatment of AIDS and other related drugs. Background technique [0002] AIDS (Acquired Immune Deficiency Syndrome) is an epidemic infectious disease caused by Human Immunodeficiency Virus (HIV). [0003] Reverse transcriptase (Reverse transcriptase, RT) plays a decisive role in the process of HIV reverse transcription from mRNA to DNA, so it has become one of the important targets for the design of anti-AIDS drugs. [0004] In the existing anti-HIV drug research, non-nucleoside reverse transcriptase inhibitors (NNRTIs) have become one of the hotspots of medicinal chemists in various countries because of their high efficiency and low toxicity. Currently, there are four anti-HIV ...
