ines has been accomplished by the cyclization of the corresponding intermediate 5-amino-4-chloro-6-(alkylamino)pyrimidines promoted by alkoxides and various N,N-dimethyl amides, where the latter act as solvent–reagents. By this three-component condensation reaction we are able to introduce an alkyl group in the 8 position of the purine ring with the concomitant nucleophilic replacement of the 6-chloro

Purines are heterocyclic aromatic organic compounds consisting of two 5‐ and 6‐membered fused rings containingnitrogen. They are present in numerous compounds, including natural products, with potent biological activity. Purine analogs are used for the treatment of acute leukemias. Thiopurine derivatives are effective antiviral (acyclovir and ganciclovir) or antitumor agents such as vidarabine, among
嘌呤是杂环芳香族有机化合物,由两个含氮的 5 元和 6 元稠环组成。它们存在于许多具有强大生物活性的化合物中,包括天然产物。嘌呤类似物用于治疗急性白血病。硫嘌呤衍生物是有效的抗病毒剂(阿昔洛韦和更昔洛韦)或抗肿瘤剂,例如阿糖腺苷,以及其他临床用途。多年来,嘌呤核已成为一个重要的药效团。它能够干扰酶和核酸的合成和功能。它也经常用于开发蛋白激酶抑制剂。我们的研究小组开发了生产嘌呤文库的新途径。其中一种途径是一锅法合成以获得 6-、8-、来自 4-烷基氨基-5-氨基-6-氯嘧啶、醇和 N,N-二甲基酰胺的 9-取代嘌呤。我们还提出了一种获得三取代嘌呤的新方法。我们能够制备多取代嘌呤库。发现该文库中的一些化合物是死亡相关蛋白激酶-1 的特异性抑制剂。该文库的主要化合物是肿瘤淋巴细胞凋亡的有效诱导剂,也降低锥虫的活力。我们在此报告了这些新嘌呤衍生物子集的 H 和 C 的明确分配。在化合物 3k 和 3n
