Described herein are small-molecule mimics of CD4, which both enter the Phe43 cavity and target Asp368 of gp120, the HIV-1 envelope protein. Also described herein are methods of using these compounds to inhibit the transmission or progression of HIV infection. These compounds exhibit antiviral potency greater than that of a known antiviral, NBD-556, with 100% breadth against clade B and C viruses. Importantly, the compounds do not activate HIV infection of CD4-negative, CCR5-positive cells, in contrast to NBD-556.
本文描述了C
D4的小分子模拟物,它们进入Phe43腔并靶向HIV-1包膜蛋白gp120的Asp368。本文还描述了使用这些化合物抑制HIV感染的传播或进展的方法。这些化合物表现出比已知抗病毒药物NB
D-556更强的抗病毒效力,对B和C类病毒具有100%的广度。重要的是,与NB
D-556相比,这些化合物不会激活C
D4阴性,CCR5阳性细胞的HIV感染。
