  摘要：

  Molecular modeling analysis of compounds belonging to the recently published series of dihydroalkoxy-benzyl-oxopyrimidines (DABOs), such as S-DABOs and DATNOs, gave support to the design of new 2,6-disubstituted benzyl-DABO derivatives as highly potent and specific inhibitors of the HIV-1 reverse transcriptase (RT). To follow up on the novel DABO derivatives, we decided to investigate the effect of electron-withdrawing substituents in the benzyl unit of the S-DABO skeleton versus their anti-HIV-1 activity. Such chemical modifications impacted the inhibitory activity, especially when two halogen units were introduced at positions 2 and 6 in the phenyl portion of the benzyl group bound to C-6 of the pyrimidine ring. Various 5-alkyl-2-(alkyl(or cycloalkyl)thio)-6-(2,B-dichloro(or 2, 6-difluoro)phenylmethyl)-3,4-dihydropyrimidin-4(3H)-ones were then synthesized and tested as anti-HIV-1 agents in both cell-based and enzyme (recombinant reverse transcriptase, rRT) assays. Among the various mono- and disubstituted phenyl derivatives, the most potent were those containing a 6-(2,6-difluorophenylmethyl) substituent (F-DABOs), which showed EC50's ranging between 40 and 90 nM and selectivity indexes up to greater than or equal to 5000. An excellent correlation was found between EC50 and IC50 values which confirmed that these compounds act as inhibitors of the HIV-1 RT. The structure-activity relationships of the newly synthesized pyrimidinones are presented herein.

  摘要：

  已经建立了用于平行溶液相合成的简单而有效的方法，以获得一系列硫尿嘧啶，然后在微波辐射下选择性地将S-苄基化，得到新的S-DABO。生物筛选导致鉴定出对高度纯化的重组人免疫缺陷病毒1型（HIV-1）逆转录酶（RT）酶（野生型和突变型）和野生型（wt）和突变型HIV具有纳摩尔活性的化合物-1株。特别是，发现20种是迄今为止报道的最有效的S-DABO（针对分离的wt酶的ID50 = 26 nM），对wt和多抗性病毒（IRLL98）HIV-1菌株均具有亚纳摩尔活性（EC50 <0.14 nM和EC50分别为0.22 nM）。

  A simple and straightforward methodology for the parallel, solution-phase synthesis of a new series of S-DABO derivatives 1 and 2, bearing aromatic substituents at the C2 and C6 positions, has been developed. Starting from potassium ethyl malonates 3, thiouracil intermediates 5 were prepared through parallel synthesis and isolated as pure products by simple extraction with ethyl acetate. Selective

  and their in vitro anti-hepatitis C virus activities have been evaluated using Huh 7.5.1 cells. Some of the compounds showed moderate anti-hepatitis C virus activities, with EC50 range from 7.53 to 0.13 μM. Among all the compounds, 6-(cyclohexylmethyl)-5-ethyl-2-((2-hydroxy-2-phenylethyl)thio)-pyrimidin-4 (3H)-one (3a) had the most promising potential in inhibiting hepatitis C virus with an EC50 value
