thiazolylhydrazone derivatives were designed, synthesized, and evaluated for their neuraminidase (NA) inhibitory activity against influenza virus H1N1 in vitro. Compounds 1 and 2 were synthesized via the one-pot reaction and compound 3 was synthesized in two steps. Pharmacological results showed that the majority of the target compounds 1, 2, and 3 exhibited moderate-to-good influenza NA inhibitory activity
设计,合成和合成了三个系列的噻唑并hydr衍生物,它们在体外对流感病毒H1N1具有神经氨酸酶(NA)抑制活性。化合物1和2通过一锅法合成,化合物3分两步合成。药理结果表明,大多数的目标化合物1,2,和3表现出中度至良好流感NA抑制活性。活性最高的化合物2g(IC 50 = 7.12μg/ ml)的NA抑制活性优于先导化合物A。进行了分子对接,以研究化合物2g与NA活性位点之间的可能相互作用。根据生物学结果,得出并讨论了初步的结构-活性关系(SAR)。此外,还进行了密度泛函理论(DFT)计算,以解释为何噻唑基hydr骨架具有NA抑制活性,尤其是具有最强抑制活性的化合物2g。
