The present invention is directed to new bifunctional compounds and methods for treating HIV infections. The bifunctional small molecules, generally referred to as ARM-HI's, 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-HI'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.
本发明涉及治疗艾滋病毒感染的新型双功能化合物和方法。这种双功能小分子一般称为 ARM-HI,通过正交途径发挥作用,抑制 gp120 与 CD4 的相互作用,并将抗 DNP 抗体募集到表达 gp120 的细胞,从而防止细胞感染和 HIV 的传播。研究表明,ARM-HI 与 CD4 竞争性地结合到 gp120 和表达 gp-120 的细胞上,从而降低病毒的感染性,如 MT-2 细胞试验所示,这种结合通过招募抗 DNP 抗体与之结合而形成三元复合物,存在于三元复合物中的抗体可促进依赖补体的 gp120 表达细胞的破坏。本文描述了化合物和方法。
