The design, synthesis, thermodynamic and crystallographic characterization of a potent, broad spectrum, second-generation HIV-1 entry inhibitor that engages conserved carbonyl hydrogen bonds within gp120 has been achieved. The optimized antagonist exhibits a sub-micromolar binding affinity (110 nM) and inhibits viral entry of clade B and C viruses (IC50 geometric mean titer of 1.7 and 14.0 muM, respectively)
设计,合成,热力学和晶体学表征了一种有效的,广谱的,第二代HIV-1进入抑制剂,该抑制剂与gp120中的保守羰基氢键结合。优化的拮抗剂表现出亚微摩尔结合亲和力(110 nM),并抑制进化枝B和C病毒的病毒进入(IC50几何平均滴度分别为1.7和14.0μM),而不会促进CD4依赖性病毒的进入。热力学特征表明(R,R)-对(S,S)-对映体的结合偏好。小分子-gp120配合物的晶体结构揭示了结晶水的置换以及与桥接片的主链羰基形成的氢键。因此,针对高度保守和结构特征化的CD4的基于结构的设计和合成:
