From our research group, it was noticed that oseltamivir derivatives targeting 150-cavity of neuraminidase enzyme (NA) could significantly increase antiviral activity. Thus, we further enriched the C5-NH2 position of oseltamivir structure to obtain more potent oseltamivir derivatives. In this article a series of oseltamivir derivatives were synthesized by modifying C5-NH2 position of oseltamivir. All the compounds were evaluated for in vitro antiviral activity against H5N1 and H5N8. Encouragingly, compounds 9a and 11e were exhibited prominent activity, which is similar to oseltamivir carboxylate (OSC) and in NAs inhibitory assay, 11e showed remarkable potency against N1 (H5N1), N2 (H5N2), N6 (H5N6) and N8 (H5N8). In addition, 11e demonstrated low cytotoxicity and no obvious toxicity at the dose of 1500 mg/kg in mice. Molecular docking studies of 9a and 11e provided a plausible rationale for the high potency against group-1 NAs. This work provided new insights to design further neuraminidase inhibitors, which can help to investigate new potent inhibitors for group-1 and group-2 shortly.

发现新颖的“双位”结合奥司他韦衍生物作为有效的流感病毒神经氨酸酶抑制剂。

从我们的研究小组中注意到,靶向150腔神经氨酸酶(NA)的奥司他韦衍生物可以显着提高抗病毒活性。因此,我们进一步丰富了奥司他韦结构的C5-NH2位置,以获得更有效的奥司他韦衍生物。本文通过修饰奥司他韦的C5-NH2位置合成了一系列奥司他韦衍生物。评估了所有化合物对H5N1和H5N8的体外抗病毒活性。令人鼓舞的是,化合物9a和11e表现出显着的活性,与奥司他韦羧酸盐(OSC)相似,并且在NAs抑制试验中,11e对N1(H5N1),N2(H5N2),N6(H5N6)和N8(H5N8)表现出显着的效力。 。此外,11e在小鼠中以1500 mg / kg的剂量显示出低细胞毒性,没有明显的毒性。9a和11e的分子对接研究为针对第1组NA的高效力提供了合理的理由。这项工作为设计进一步的神经氨酸酶抑制剂提供了新的见识,可以帮助不久后研究第1组和第2组的新型有效抑制剂。
