The interaction between the HIV-1 transactivator protein Tat and RNA response element (TAR) plays a critical
role in HIV-1 transcription. Based on the pharmacophore model of reported inhibitors, a series of novel substituted
guanidine indole derivatives was designed, synthesized and evaluated for their in vitro HIV-1 and HIV-2 inhibitory activity
using the IIIB strain and ROD strain, respectively. Preliminary biological evaluation indicated that three compounds
exhibited marked inhibitory activity against HIV-1 IIIB. Quite unexpectedly, compound a-7 was also endowed with the
moderate anti-HIV-2 potency (EC50 = 58.14 µM). In addition, preliminary discussion on the activity results and molecular
modeling of these new analogues were presented in this manuscript.

生物评估表明,三种化合物对 HIV-1 IIIB 具有明显的抑制活性。出乎意料的是,化合物 a-7 还具有中等程度的抗 HIV-2 效力(
EC50 = 58.14 µM)。此外,本手稿还对这些新类似物的活性结果和分子模型进行了初步讨论。
