  发现二氢-烷氧基-苄基-氧嘧啶作为有前途的抗流感病毒剂

  摘要：

  合成了一系列新颖的二氢-烷氧基-苄基-氧嘧啶衍生物，并评估了它们在Madin-Darby犬肾细胞中对流感病毒的活性。四个二氢-烷氧基苄基oxopyrimidine衍生物（4A1，4A2，4A3，和4D1）显示对流感病毒有效的活性。其中，化合物4A3与抗流感A宽的活性最有前途的引线（抗病毒EC 50倍的图9和18的值 μ米分别用于A / H1N1和A / H3N2亚型）和B型流感病毒（EC 50：33  μ米）。这些二氢-烷氧基-苄基-氧嘧啶衍生物的抗病毒作用机制必须与目前批准的针对病毒M2或神经氨酸酶蛋白的抗流感病毒药物完全不同。二氢烷氧基苄基氧嘧啶衍生物代表了进一步优化和开发新型抗流感病毒剂的新途径。

  摘要：

  A series of dihydro-alkylthio-benzyl-oxopyrimidines (S-DABOs) bearing a 2-aryl-2-oxoethylsulfanyl chain at pyrimidine C2, an alkyl group at C5, and a 2,6-dichloro-, 2-chloro-6-fluoro-, and 2,6-difluoro-benzyl substitution at C6 (oxophenethyl-S-DABOs, 6-8) is here described. The new compounds showed low micromolar to low nanomolar (in one case subnanomolar) inhibitory activity against wt HIV-1. Against clinically relevant HIV-1 mutants (K103N, Y181C, and Y188L) as well as in enzyme (wt and K103N, Y181I, and L1001 mutated RTs) assays, compounds carrying an ethylliso-propyl group at C5 and a 2,6-dichloro-/2-chloro-6-fluoro-benzyl moiety at C6 were the most potent derivatives, also characterized by low fold resistance ratio. Interestingly, the structure-activity relationship (SAR) data drawn from this DABO series are more related to HEPT than to DABO derivatives. These findings were at least in part rationalized by the description of a fair superimposition between the 6-8 and TNK-651 (a HEPT analogue) binding modes in both WT and Y181C RTs.

  A series of new 5‐alkyl‐2‐phenylaminocarbonylmethylthiopyrimidin‐4(3H)‐ones bearing variously substituted arylmethyl moieties at the C6 position of the pyrimidine ring were synthesized and evaluated for anti‐HIV activity in MT‐4 cells. Most of these new congeners exhibited moderate to good activities against the wild‐type virus, with EC50 values in the range of 1.40–0.19 μM. Among them, 2‐[(4‐cyan

  A series of novel S-DABO analogues, characterized by different substitution patterns at positions 2, 5, and 6 of the heterocyclic ring, were synthesized in a straightforward fashion by means of parallel synthesis and evaluated as inhibitors of human immunodeficiency virus type-1 (HIV-1). Most of the compounds proved to be highly active on the wild-type enzyme both in enzymatic and cellular assays, with one of them emerging as the most active reverse transcriptase inhibitor reported so far (EC50wt = 25 pM). The general loss of potency displayed by the compounds toward clinically relevant mutant strains was deeply studied through a molecular modeling approach, leading to the evidence that the dynamic of the entrance in the non-nucleoside binding pocket could represent the basis of the inhibitory activity of the molecules.
