  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.

Biological screening led to the identification of compounds with nanomolar activity toward both the highly purified recombinant human immunodeficiency virus type 1 (HIV-1) reverse transcriptase (RT) enzyme (wild-type and mutants)

  new series of S‐DABO/N‐DABO derivatives were synthesized to obtain additional SAR information on the C2‐position and in particular to improve ADME properties while maintaining a good activity profile against HIV‐1 RT. In vitro ADME properties (PAMPA permeation, water solubility, and metabolic stability) were also experimentally evaluated for the most interesting compounds to obtain a reliable indication

  以前旨在探索C2功能化S - DABOs SAR的研究表明，该位置的取代基在抑制野生型RT和耐药酶（尤其是K103N突变体）中起着关键作用。环丙基的引入使我们发现了一种有效的抑制剂，该抑制剂具有对野生型RT的皮摩尔活性和对许多关键突变体形式（如K103N）的纳摩尔活性。尽管该化合物具有出色的抗病毒特性，但它仍具有许多S- DABO类似物典型的次优ADME特性，但是，它可以作为抗HIV杀微生物剂的一种有前途的候选药物。在当前的工作中，新的S ‐DABO / N系列合成DABO衍生物以获得有关C2位置的其他SAR信息，尤其是在改善ADME特性的同时，还保持了针对HIV-1 RT的良好活性。还通过实验评估了最有趣的化合物的体外ADME特性（PAMPA渗透性，水溶性和代谢稳定性），以获得口服后血浆水平的可靠指示。
