The present invention is directed to new bifunctional compounds and methods for treating HIV infections. The bifunctional small molecules, generally referred to as ARM-H′ function through orthogonal pathways, by inhibiting the gp120-CD4 interaction, and by recruiting anti-DNP antibodies to gp120-expressing cells, thereby preventing cell infection and spread of HIV. It has been shown that ARM-H's bind to gp120 and gp-120 expressing cells competitively with CD4, thereby decreasing viral infectivity as shown by an MT-2 cell assay, the binding leading to formation of a ternary complex by recruiting anti-DNP antibodies to bind thereto, the antibodies present in the ternary complex promoting the complement-dependent destruction of the gp120-expressing cells. Compounds and methods are described herein.
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。
