as potential anti-HIV-1 and antimicrobial agents. Also, from the literature, S-substituted pyrimidin-4-ones A and B exhibited interesting anti-HIV-1 activity. To further investigate the synthesis, tools and biological activities, we synthesized several new thienopyrimidine derivatives derived from thieno[2,3-d]-pyrimidine-2,4-dithione (3a,b) The compounds were designed to comprise the heterocyclic substituents
以前,我们合成并评估了几种噻吩并嘧啶衍生物,它们含有通过2至4个原子的间隔基与C-2处的嘧啶-2-硫酮核连接的杂环取代基,作为潜在的抗HIV-1和抗菌剂。同样,从文献中,S-取代的嘧啶-4-酮A和B表现出令人感兴趣的抗HIV-1活性。为了进一步研究其合成,工具和生物学活性,我们合成了几种新的衍生自噻吩并[2,3- d ]-嘧啶-2,4-二硫酮(3a,b)这些化合物被设计为包含在C-2处直接连接至噻吩并嘧啶核的杂环取代基。此外,还制备了衍生自2-硫代噻吩并嘧啶的各种相关的三唑并[4,3- a ]苯并噻吩并[2,3- d ]嘧啶作为等排物。中合成的衍生物3 - 18,化合物3a中,图8A,图10A,13A和14A分别示出了在128毫克/毫升或更少完全抑制。
