A new synthetic route to obtain symmetric disubstituted alkyl/arylaminopyrimidines under mild conditions is presented, which can be used to generate newpurine libraries for drug discovery. We investigated the unexpected reaction of 6-alkoxy-4-chloro-5-nitropyrimidines with primary amines, which produced disubstituted dialkyl/arylamine pyrimidines instead of the expected 6-alkoxy-4-alkylamine-5-nitropyrimidines

group in position 5. In particular, the reactions of II with alkoxybenzylamines, 4-piperidinyl-, and 4-morpholinylpropylamines are completed within 6 h at room temperature or 1 h in a boiling ethanol solution of the initial reagents. Note that monoaminopyrimidines could not be isolated even in the former case. The rate of chlorine displacement depends also on the degree of nucleophilicity of the amine
之前,我们合成并表征了一系列在嘧啶循环中含有各种官能团的 5-(对烷氧基苄基)和 5-(3-碳乙氧基-4-烷氧基苄基)嘧啶(参见 [1] 和其中的参考文献)。在继续这些研究的过程中,并考虑到在嘧啶循环的第 5 位取代硝基和磺基可能有利于抗肿瘤活性,我们通过该方案进行了 5-硝基嘧啶 I lia IIIj 和 Va Vf 的合成。用于合成化合物 1II 和 V 的初始试剂是 5-硝基-4,6-二氯嘧啶 (II),通过在二甲基苯胺的存在下,在 100 I IO - 下加热化合物 I [2] 与过量的磷酰氯而获得。在这些条件下,II 的产率从公布的 55% [3] 水平增加到 60 65%。二氯嘧啶 II 的胺化是由电子受体 - 5 位硝基的存在促进的。 特别是,II 与烷氧基苄胺、4-哌啶基-和 4-吗啉基丙胺的反应在室温下 6 小时内完成或在初始试剂的沸腾乙醇溶液中放置 1 小时。请注意

activity of 23 purine analogs with different substitutions in the complementary chains of their purine rings. We sequentially screened the compounds' capacity to inhibit parasite growth, their toxicity in Vero and HepG2 cells, and their specific capacity to inhibit the development of amastigotes. We then used in-silico docking to identify their likely targets.ResultsEight compounds showed specific anti-parasitic
