合成了带有咪唑,金刚烷和相关结构的抑制剂,并针对WT,S31N和S31N-L26I突变M2通道进行了测试。尽管金刚烷胺(1)仅抑制WT M2通道,但含有咪唑和金刚烷基团的化合物6对WT和突变M2通道显示出良好的抑制活性。α-胺的立体化学和碱性p K a对抑制剂的活性很重要,我们的数据表明,天然组氨酸的衍生物对M2通道的活性比非天然组氨酸的衍生物高。我们当前结果的意义在于,我们已经建立了一种针对WT和突变型M2通道针对甲型流感的药物发现的前瞻性策略。

Provided are compounds according to formula (Ia) or (Ib) as described herein, that are capable of modulating the activity of influenza viruses (e.g., influenza A virus), for example, via interaction with the M2 transmembrane protein, and other similar viroporins. Also provided are methods for treating an influenza A-affected disease state or infection comprising administering a composition comprising one or more compounds according to according to formulas (Ia′) or (Ib), as described herein.
Inhibitors bearing the imidazole, adamantane and related structures were synthesized and tested against WT, S31N and S31N‐L26I mutantM2channels. Although amantadine (1) only inhibited WT M2channel, compound 6 containing the imidazole and adamantane groups showed good inhibitory activity to WT and mutantM2channels. The stereochemistry and basic pKa of α‐amine are important for the activity of inhibitors
