  BIFUNCTIONAL MOLECULES WITH ANTIBODY-RECRUITING AND ENTRY INHIBITORY ACTIVITY AGAINST THE HUMAN IMMUNODEFICIENCY VIRUS

  摘要：

  本发明涉及新的双功能化合物和治疗HIV感染的方法。这些双功能小分子通常被称为ARM-H'，通过抑制gp120-CD4相互作用和招募抗DNP抗体到gp120表达细胞上，从而通过正交途径发挥作用，防止细胞感染和HIV的传播。已经证明ARM-H与gp120和gp-120表达的细胞竞争性地结合CD4，从而通过MT-2细胞测定减少病毒的感染性，结合导致三元复合物的形成，招募抗DNP抗体结合到其中，三元复合物中的抗体促进gp120表达细胞的补体依赖性破坏。本文描述了化合物和方法。

  HIV/AIDS is a global pandemic for which new treatment strategies are desperately needed. We have designed a novel small molecule, designated as ARM-H, that has the potential to interfere with HIV survival through two mechanisms: (1) by recruiting antibodies to gp120-expressing virus particles and infected human Celts, thus enhancing their uptake and destruction by the human immune system, and (2) by binding the viral glycoprotein gp120, inhibiting its interaction with the human protein CD4 and preventing virus entry. Here we demonstrate that ARM-H is capable of simultaneously binding gp120, a component of the Env surface viral glycoprotein (found on the surface of both HIV and virus-infected cells) and anti-2,4-dinitrophenyl antibodies (already present in the human bloodstream). The ternary complex formed between the antibody, ARM-H, and gp120 is immunologically active and leads to the complement-mediated destruction of Env-expressing cells. Furthermore, ARM-H prevents virus entry into human T-cells and should therefore be capable of inhibiting virus replication through two mutually reinforcing mechanisms (inhibition of virus entry and antibody-mediated killing). These studies demonstrate the viable anti-HIV activity of antibody-recruiting small molecules and have the potential to initiate novel paradigms in HIV treatment.
