  摘要：

  摘要 我们比较了57种金刚烷胺及其类似物对具有丝氨酸-31 M2质子通道（通常称为WT M2通道，对金刚烷胺敏感）的甲型流感病毒的抗流感病毒效力。我们还测试了其中一部分化合物对金刚烷胺耐药的 L26F、V27A、A30T、G34E M2 突变通道病毒的抑制作用。四种化合物在体外抑制 WT M2 病毒的效力为中等纳摩尔，27 种化合物的效力为亚微摩尔至低微摩尔。有几种化合物在体外以亚微摩尔至低微摩尔的效力抑制 L26F M2 病毒，但根据电生理学（EP）测定，只有三种化合物阻断了 L26F M2 介导的质子电流。通过 EP 试验发现，一种化合物是 WT、L26F 和 V27A M2 通道的三重阻断剂，但在体外不抑制 V27A M2 病毒；一种化合物在体外抑制 WT、L26F 和 V27A M2，但不阻断 V27A M2 通道。一种化合物通过 EP 只阻断了 L26F M2 通道，但没有抑制病毒复制。分子动力学模拟显示，这种三重阻断剂化合物的长度与利曼他定相当，但由于其周长更大，可以结合并阻断 V27A M2 通道，而 MAS NMR 则显示了该化合物与 M2(18-60) WT 或 L26F 或 V27A 的相互作用。

  Aminoadamantanes with Persistent in Vitro Efficacy against H1N1 (2009) Influenza A

  摘要：

  A series of 2-adamantanamines with alkyl adducts of various lengths were examined for efficacy against strains of influenza A including those having an S31N mutation in M2 proton channel that confer resistance to amantadine and rimantadine. The addition of as little as one CH2 group to the methyl adduct of the amantadine/rimantadine analogue, 2-methyl-2-aminoadamantane, led to activity in vitro against two M2 S31N viruses A/Calif/07/2009 (H1N1) and A/PR/8/34 (H1N1) but not to a third A/WS/33 (H1N1). Solid state NMR of the transmembrane domain (TMD) with a site mutation corresponding to S31N shows evidence of drug binding. But electrophysiology using the full length S31N M2 protein in HEK cells showed no blockade. A wild type strain, A/Hong Kong/1/68 (H3N2) developed resistance to representative drugs within one passage with mutations in M2 TMD, but A/Calif/07/2009 S31N was slow (>8 passages) to develop resistance in vitro, and the resistant virus had no mutations in M2 TMD. The results indicate that 2-alkyl-2-aminoadamantane derivatives with sufficient adducts can persistently block p2009 influenza A in vitro through an alternative mechanism. The observations of an HA1 mutation, N160D, near the sialic acid binding site in both 6-resistant A/Calif/07/2009(H1N1) and the broadly resistant A/WS/33(H1N1) and of an HA1 mutation, I325S, in the 6-resistant virus at a cell-culture stable site suggest that the drugs tested here may block infection by direct binding near these critical sites for virus entry to the host cell.

  We compared the anti‐influenza potencies of 57 adamantyl amines and analogs against influenza A virus with serine‐31 M2 proton channel, usually termed as WT M2 channel, which is amantadine sensitive. We also tested a subset of these compounds against viruses with the amantadine‐resistant L26F, V27A, A30T, G34E M2 mutant channels. Four compounds inhibited WT M2 virus in vitro with mid‐nanomolar potency, with 27 compounds showing sub‐micromolar to low micromolar potency. Several compounds inhibited L26F M2 virus in vitro with sub‐micromolar to low micromolar potency, but only three compounds blocked L26F M2‐mediated proton current as determined by electrophysiology (EP). One compound was found to be a triple blocker of WT, L26F, V27A M2 channels by EP assays, but did not inhibit V27A M2 virus in vitro, and one compound inhibited WT, L26F, V27A M2 in vitro without blocking V27A M2 channel. One compound blocked only L26F M2 channel by EP, but did not inhibit virus replication. The triple blocker compound is as long as rimantadine, but could bind and block V27A M2 channel due to its larger girth as revealed by molecular dynamics simulations, while MAS NMR informed on the interaction of the compound with M2(18–60) WT or L26F or V27A.
