A series of d(5′TGGGAG3′) sequences, 5′-conjugated with a variety of aromatic groups through phosphodiester linkages, were synthesized, showing CD spectra diagnostic of parallel-stranded, tetramolecular G-quadruplex structures. When tested for anti-HIV-1 and HIV-2 activity, potent inhibition of HIV-1 infection in CEM cell cultures was found, associated with high selectivity index values. Surface Plasmon Resonance assays revealed specific binding to HIV-1 gp120 and gp41.
我们合成了一系列 d(5′TGGGAG3′)序列,这些序列的 5′通过
磷酸二酯连接与各种芳香基团共轭,显示出平行链、四分子 G-四联结构的 CD 光谱诊断。在对其进行抗 HIV-1 和 HIV-2 活性测试时,发现它对 C
EM 细胞培养物中的 HIV-1 感染有很强的抑制作用,并具有很高的选择性指数值。表面等离子共振检测显示,它与 HIV-1 gp120 和 gp41 有特异性结合。
