varied with substituents in different positions. This gave a range of CD4 down-modulation potencies that correlated well with anti-HIV-1 activities. The side arms of 21 of the new benzyl-tailed analogues were modeled by means of quantum mechanical calculations. For CADA analogues with arenesulfonamide side arms, the pIC50 values for CD4 down-modulation correlated with the component of the electric dipole
环三氮杂二磺酰胺通过与C
D4信号肽结合来下调表面C
D4受体的表达,从而防止HIV进入细胞。根据两点结合模型,已经设计并合成了28个带有苄基尾基的新的不对称类似物和9个带有环己基甲基尾巴的不对称类似物。最有效的新型C
D4下调器(40(CK147); IC50 63 nM)具有4-二甲基
氨基苯磺酰基侧臂。两个侧臂之一在不同位置具有取代基。这给出了一系列与抗HIV-1活性很好相关的C
D4减量调节能力。通过量子力学计算对21种新的苄基尾类似物的侧臂进行建模。对于带有
芳烃磺酰胺侧臂的C
ADA类似物,
