  5-Alkyl-2-(alkylthio)-6-(2,6-dihalophenylmethyl)-3,4-dihydropyrimidin-4(3H)-ones:  Novel Potent and Selective Dihydro-alkoxy-benzyl-oxopyrimidine Derivatives

  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.

  取代的 1-苄基-1-甲氧基-2-硝基乙烯的动力学和热力学酸度。与其他硝基烷烃相比，显着降低了过渡态不平衡

  摘要：

  六个取代的 1-苄基-1-甲氧基-2-硝基乙烯（2-Z 与 Z = m-NO(2)、m-CF(3)、m-Cl、H、p-Me、p-MeO）的酸度常数) 及其各自的硝基酸在 20 摄氏度的 50% DMSO-50% 水 (v/v) 中测定。获得了所有六个 2-Z 由 OH(-) 和哌啶可逆去质子化的动力学数据，以及哌嗪、1-（2-羟乙基）哌嗪和吗啉在同一溶剂中对 2-NO(2)() 进行可逆去质子化。这些数据可以确定 Brønsted 系数 alpha（取决于 2-Z 的酸度）和 beta（取决于胺碱度）。α > β 的事实表明存在过渡态不平衡，然而，这比芳基硝基甲烷的去质子化要小得多。

  Acidity constants of six substituted 1-benzyl-1-methoxy-2-nitroethylenes (2-Z with Z = m-NO(2), m-CF(3), m-Cl, H, p-Me, p-MeO) and their respective nitronic acids were determined in 50% DMSO-50% water (v/v) at 20 degrees C. Kinetic data were obtained on the reversible deprotonation of all six 2-Z by OH(-) and piperidine and on the reversible deprotonation of 2-NO(2)() by piperazine, 1-(2-hydroxyethyl)piperazine

  An operationally simple, and cost efficient conversion of carboxylic acids into hydroxamic acid derivatives via a high‐energy mechanochemical activation is presented. This ball milling methodology was applied to a wide variety of carboxylic acids dramatically improving purification issues associated with this class of molecules, which still remain one of the main bottlenecks of classical methodologies
