substituent (R) attached at the N-6 position of 9. This study describes the syntheses and anti-HIV-1 testing of analogues with variations of the five-membered urea ring of the 4,5,6,7-tetrahydro-5-methylimidazo[4,5,1-jk] [1,4]benzodiazepin-2(1H)-one (TIBO) structures. Although many different rings were synthesized to replace the cyclic urea of TIBO, most were found to be inactive in inhibiting the replication
在该系列的第一篇论文中,揭示了一种具有抗HIV-1活性的新结构,并合成了类似物以探讨9位N-6位上连接的取代基(R)的变化与构效关系。描述了具有4,5,6,7-四氢-5-甲基咪唑[4,5,1-jk] [1,4]的五元脲环变异的类似物的合成和抗HIV-1测试苯并二氮杂-2-2(1H)-一(TIBO)结构。尽管合成了许多不同的环来取代TIBO的环状脲,但发现大多数环在抑制MT-1细胞中HIV-1病毒的复制方面没有活性。例外是用硫或硒代替尿素氧,得到相应的硫脲或硒脲。发现它们比氧气对应物更具活性。合成并测试了一小部分类似物,可以直接比较尿素和硫脲衍生物。毫无例外,后者总是比前者更加活跃。发现该系列(8d)中活性最高的化合物抑制HIV-1病毒,其IC50为0.012 microM,与AZT相当。
