To yield potent neuraminidase inhibitors with improved drug resistance and favorable drug-like properties, two series of novel oseltamivir derivatives targeting the 150-cavity of neuraminidase were designed, synthesized, and biologically evaluated. Among the synthesized compounds, the most potent compound 43b bearing 3-floro-4-cyclopentenylphenzyl moiety exhibited weaker or slightly improved inhibitory
为了产生具有改善的耐药性和良好的类药特性的强效神经氨酸酶抑制剂,设计、合成和生物学评估了两个系列的靶向 150 腔神经氨酸酶的新型奥司他韦衍生物。在合成的化合物中,与羧酸奥司他韦 ( OSC ) 相比,具有 3-氟-4-环戊烯基苯基部分的最有效化合物 43b 对 H1N1、H5N1 和 H5N8 的野生型神经氨酸酶 (NA) 的抑制活性较弱或略有改善。令人鼓舞的是,43b针对 H5N1–H274Y 和 H1N1–H274Y 突变体 NA 的活性分别比OSC高 62.70 倍和 5.03 倍。在细胞抗病毒试验中,43b与OSC相比,对 H1N1、H5N1 和 H5N8 具有等效或更有效的活性,在高达 200 μM 时没有明显的细胞毒性。值得注意的是,43b在含胚卵模型中显示出强大的抗病毒功效,其中对 H5N1 和 H5N8 的保护作用类似于OSC。实施分子对接研究以揭示结合口袋中43b的结合
