antiviral potency or increased cytotoxicity to MT-4 cells. Finally, we synthesized a series of analogues in which the ring size of the bis-pyridyl macrocycles was varied between 12 and 16 members per ring including the py[iso-14]aneN(4) ring system, an isomer of the py[14]aneN(4) macrocycle. The p-phenylenebis(methylene)-linked dimer of the py[iso-14]aneN(4) (AMD3329) displayed the highest antiviral activity
Bis-tetraazamacrocycles,例如bicyclam AMD3100,是一类有效的和选择性的抗HIV-1和HIV-2药剂,它们通过结合趋化因子受体CXCR4(X4病毒进入的共同受体)而抑制病毒复制。为了优化双氮杂双环类化合物的抗HIV-1和HIV-2活性,合成了一系列类似物,这些类似物包含中性杂原子(氧,硫)或杂芳香族(pK(a)比仲胺低)替代AMD3100的氨基。将一个或多个杂原子(例如氧或硫)引入对亚苯基双(亚甲基)连接的二聚体的大环中(生成N(3)X或N(2)X(2)双大环),得到类似物大大降低了抗HIV-1(III(B))和抗HIV-2(ROD)的效力。此外,双硫类似物对MT-4细胞也有明显的细胞毒性。然而,具有掺入大环骨架中的单个吡啶基团的双-四氮杂大环化合物显示出与其饱和的脂族对应物相当的抗HIV-1和HIV-2效能。py [14] aneN(4)大环的对亚苯基
