It was found that some of the synthesized compounds showed interesting antimicrobial activity (by agar diffusion method) against some gram-positive and gram-negative bacilli strains. GRAPHICAL ABSTRACT On the basis of some our previous results we have carried out the synthesis of several new polyheterocyclic compounds with
摘要 考虑到先前获得的一些多杂环化合物(含有不同杂原子)的生物学结果,特别是几种 8-氨基-5-异丙基-2,2-二甲基-10-(甲硫基)-1,4-二氢-2H- pyrano[4'',3'':4',5']pyrido[3',2':4,5]thieno[3,2-d]pyrimidines Ia-v 我们进行了二十一 8-氨基-5-异丁基-2,2-二甲基-10-(甲硫基)-1,4-二氢-2H-吡喃[4'',3'':4',5']吡啶并[3',2': 4,5]噻吩并[3,2-d]嘧啶 6. 因此,我们稍微修改了之前研究的 I 的结构,在 C-5 处引入了异丁基,而不是之前检查的异丙基,以查看这种变化(稍微改变亲脂性)会影响生物活性。此外还合成了噻吩并[3,2-d]嘧啶-8-硫酮7及其S-烷基化8。发现一些合成的化合物对一些革兰氏阳性和革兰氏阴性杆菌菌株显示出有趣的抗菌活性(通过琼脂扩散法)。图形摘要
