bicyclam AMD3100(分子式重量 830)通过 CXCR4 共受体阻断 HIV-1 进入和膜融合,但不通过 CCR5。 AMD3100 阻止单克隆抗体 12G5 与 CXCR4 结合,但对单克隆抗体 2D7 与 CCR5 结合没有影响。它还抑制 CXC 趋化因子 SDF-1 α 与 CXCR4 的结合以及随后的信号转导,但 bur 本身不会引起信号传导,并且对通过 CCR5 的 RANTES 信号传导没有影响。因此,AMD3100 阻止 CXCR4 作为 HIV-1 辅助受体和 CXC 趋化因子受体发挥作用。开发HIV-1进入的小分子抑制剂是可行的。
The bicyclam AMD3100 (formula weight 830) blocks HIV-1 entry and membrane fusion via the CXCR4 co-receptor, but not via CCR5. AMD3100 prevents monoclonal antibody 12G5 from binding to CXCR4 but has no effect on binding of monoclonal antibody 2D7 to CCR5. It also inhibits binding of the CXC-chemokine, SDF-1 alpha, to CXCR4 and subsequent signal transduction, bur does not itself cause signaling and has no effect on RANTES signaling via CCR5. Thus, AMD3100 prevents CXCR4 functioning as both a HIV-1 co-receptor and a CXC-chemokine receptor. Development of small molecule inhibitors of HIV-1 entry is feasible.
