amines such as amantadine are well-characterized M2 channel blockers, useful for treating influenza. Herein we report our surprising findings that charge-neutral, bulky isocyanides exhibit activities similar to--or even higher than--that of amantadine. We also demonstrate that these isocyanides have potent growth inhibitory activity against the H5N1 virus. The -NH2 to -N≡C group replacement within current
碱性笨重胺(如金刚烷胺)是特征明确的M2通道阻滞剂,可用于治疗流感。在本文中,我们报告了令人惊讶的发现,即电荷中性的大体积异氰酸酯显示出与金刚烷胺相似或什至更高的活性。我们还证明了这些异氰化物对H5N1病毒具有有效的生长抑制活性。发现当前抗流感药物中的-NH2至-N≡C基团取代可在低微摩尔浓度下提供具有高活性的化合物。例如,通过MTT和噬斑减少测定法测定的1-异氰基金刚烷(27)的效力提高了十倍,对金刚烷胺敏感的H5N1病毒的EC50值为0.487μm,而未显示出细胞毒性。此外,
