    • The present invention relates to the use of a Vif inhibitor and an APOBEC3G (A3G) activator in combination to inhibit HIV infectivity in a host cell and to treat or prevent HIV infection or AIDS in a patient. In one embodiment, the present invention relates to a method for inhibiting infectivity of HIV in a host cell, which method comprises contacting a host cell comprising A3G host defense factor with a combination of antiviral-effective amounts of a Vif inhibitor and an A3G activator, thereby inhibiting infectivity of HIV in the host cell by simultaneously inhibiting Vif-dependent degradation of A3G and activating A3G deaminase activity in the host cell, where the Vif inhibitor inhibits Vif-dependent degradation of A3G by disrupting or inhibiting dimerization of Vif in the host cell, and where the A3G activator activates A3G deaminase activity by disrupting or inhibiting A3G:nucleic acid molecule interaction in the host cell.
    • 本发明涉及组合的Vif抑制剂和APOBEC3G(A3G)激活剂在宿主细胞中抑制HIV感染性并在患者中治疗或预防HIV感染或AIDS的用途。 在一个实施方案中,本发明涉及一种抑制宿主细胞中HIV感染性的方法,该方法包括将包含A3G宿主防御因子的宿主细胞与抗病毒有效量的Vif抑制剂和A3G活化剂的组合物接触, 从而通过同时抑制宿主细胞中的A3G的Vif依赖性降解和激活A3G脱氨酶活性来抑制HIV宿主细胞的感染性,其中Vif抑制剂通过破坏或抑制宿主细胞中Vif的二聚化来抑制A3G的Vif依赖性降解 ,并且其中A3G活化剂通过破坏或抑制宿主细胞中的A3G:核酸分子相互作用来激活A3G脱氨酶活性。
