Three diazabicyclo analogs of BMS-378806, in which the axial methyl group present on its piperazine ring is replaced by a carbon bridge, were synthesized and tested, through a viral neutralization assay, on a panel of six pseudoviruses. The diazabicyclooctane and -nonane derivatives maintained a significant infectivity reduction power, whereas the diazabicycloheptane derivative was much less effective
BMS-378806 的三个二氮杂双环类似物,其中存在于其哌嗪环上的轴向甲基被碳桥取代,通过病毒中和试验在一组六个假病毒上合成和测试。二氮杂双环辛烷和壬烷衍生物保持了显着的降低传染性的能力,而二氮杂双环庚烷衍生物的效果要差得多。建模研究允许将抗病毒活性与化合物的构象偏好联系起来。此外,与 BMS-378806 类似,理论计算预测存在不同的构象族,对应于化合物的两个平面酰氨基功能的可能排列。高场 1 H NMR 光谱证实了这些结果,因为它们显示了两个不同的信号系列。
