  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：

  二氢烷氧基苄基氧嘧啶（DABOs），一种新型的非核苷类逆转录酶抑制剂的各种硫代类似物，在体外选择性地抑制了HIV-1的繁殖。在C-5 H取代的6-苄基-3,4-二氢-4-氧嘧啶中，在嘧啶环的C-2处引入烷硫基或环烷硫基取代基导致衍生物（S-DABO）最多达到10个-强于烷氧基或环烷氧基的对应物。在2-（烷硫基）-6-苄基尿嘧啶的苄基部分的3'-位处进一步引入甲基，降低了细胞毒性，从而导致更具选择性的化合物。在C-5甲基取代的S-DABO中，许多衍生物显示的EC50值低至0.6 microM，并且在高至300 microM的剂量下没有细胞毒性。在C-5双甲基取代的系列中，观察到更明显的细胞毒性，并且在亚苄基的3'-位处进一步引入甲基导致抗病毒活性完全丧失。S-DABO，即2-（烷硫基）-6-苄基-3,4-二氢-4-氧嘧啶，是通过使适当的（苯基乙酰基）乙酸甲酯或它们的2-甲基化合物与硫脲反应生成6-苄基-4合成的-氧代-1

  double methyl-substituted series, a more pronounced cytotoxicity was observed and the further introduction of a methyl at the 3'-position in the benzylidene group resulted in total loss of antiviral activity. S-DABOs, namely 2-(alkylthio)-6-benzyl-3,4-dihydro-4-oxopyrimidines, were synthesized by reacting proper methyl (phenylacetyl)acetates or their 2-methyl compounds with thiourea to afford 6-benzyl-4-oxo-1
