strongly suggested the synthesis of the designed amino-DABOs. F(2)-NH-DABOs were shown to be highly active in both anti-RT and anti-HIV biological assays with IC(50) and EC(50) comparable with that of the reference compound MKC-442. Interestingly, 2-cyclopentylamino-6-[1-(2,6-difluorophenyl)ethyl]-3,4-dihydro-5-methyl pyrimidin-4(3H)-one (9d) was active against the Y181C HIV-1 mutant strain at submicromolar
二氢-烷氧基-苄基-氧嘧啶(DABO)是在过去十年中开发的强大的NNRTIs系列。试图提高其效力和选择性的尝试导致了硫代DABO(S-DABO),DATNO和二氟硫代DABO(F(2)-S-DABO)。最近,我们报道了S-DABO系列新型构象受限亚型的合成和分子模型研究,其特征为在连接嘧啶环与芳基部分的亚甲基键上存在取代基(Mai,A.等。 J. Med。Chem。2001,44,2544-2554)。现在,我们报告四个新DABO原型(5-烷基-2-环戊基氨基-6- [1-(2,6-二氟苯基)烷基] -3,4-二氢嘧啶-4的计算机辅助设计,合成和生物学评估。 (3H)-ones,F(2)-NH-DABOs,其中相关的F(2)-S-DABOs的硫原子被氨基取代。对于这些研究,我们将共结晶的MKC-442 / RT复合物用作参考模型。新设计的F(2)-NH-DABOs与Autodock的对接研
