Postulating that fusing a pyridine ring bearing hydrophobic substituents into the macrocyclic scaffold of CADA compounds may lead to potent compounds with improved properties, 17 macrocycles were synthesized, 14 with 12-membered rings having an isobutylene head group, two arenesulfonyl side arms, and fused pyridine rings bearing a para substituent. The analogs display a wide range of CD4 down-modulating
CADA 化合物选择性地下调人类细胞表面 CD4 蛋白,并作为 HIV 进入抑制剂和哮喘、类风湿性关节炎、糖尿病和某些癌症的药物受到关注。假设将带有疏水性取代基的吡啶环融合到 CADA 化合物的大环支架中可能会产生具有改进性能的有效化合物,合成了 17 个大环,14 个具有具有异丁烯头基团、两个芳烃磺酰基侧臂和稠合吡啶的 12 元环带有对位取代基的环。这些类似物显示出广泛的 CD4 下调和抗 HIV 效力,其中一些效力高于 CADA,证明效力不需要 12 元环中的强碱性氮原子,并且疏水取代基增强了抗 HIV 的效力吡啶稠合的 CADA 化合物。
