A set of dimeric analogues of known rhinovirus capsid-binders Pleconaril 1 and Pirodavir 55 has been synthesized and tested against two representative human rhinovirus (HRV) strains. Dimers with linker lengths ranging from five atoms up to approximately 60 atoms were prepared by coupling various functionalized monomeric precursors. Many of the dimers showed activity against HRV, with the most active compounds being those with the shorter linking groups. The lower activity of all the dimers relative to similar monomeric compounds, and especially the low activity of the longest dimers, suggests that cooperative bivalent binding is not occurring with any of these compounds.
我们合成了一组已知鼻病毒荚膜结合剂 Pleconaril 1 和 Pirodavir 55 的二聚体类似物,并针对两种具有代表性的人类鼻病毒(HRV)毒株进行了测试。通过偶联各种功能化单体前体,制备出了链接长度从 5 个原子到约 60 个原子不等的二聚体。许多二聚体都显示出了抗 HRV 的活性,其中连接基团较短的化合物活性最高。与类似的单体化合物相比,所有二聚体的活性都较低,尤其是最长二聚体的活性较低,这表明这些化合物都没有发生合作性二价结合。
