摘　　要：为了发现高活性的抗病毒化合物,以蓝刺头碱为先导,运用骨架跃迁策略,设计合成了15个含有酰腙吲哚片段的蓝刺头碱衍生物,并通过^(1)H NMR、^(13)C NMR和HRMS确证了其结构,研究了其对烟草花叶病毒(TMV)的钝化、治疗和保护活性。结果表明,部分化合物具有较高的抗TMV活性。其中,化合物4n(43.5%,40.1%,38.7%)抗TMV的钝化、治疗和保护活性高于病毒唑和先导化合物L2。化合物4d(40.8%)、4f(42.0%)对TMV的钝化活性优于病毒唑(38.6%)和先导化合物L2(40.5%)。化合物4I(38.4%)对TMV的钝化活性与病毒唑(38.6%)相当。化合物4f对TMV的保护活性(36.4%)与病毒唑(37.2%)相当。化合物4n有望成为一种潜在的抗病毒农药。In order to discover highly active antiviral compounds,echinopsine was used as the lead and 15 echinopsine derivatives containing the acylhydrazone indole fragments were designed and synthesized by scaffold hopping strategy.Their structures were characterized using^(1)H NMR,^(13)C NMR and HRMS.The in vivo antiviral activities against tobacco mosaic virus(TMV)were evaluated in three modes(inactivation,curative,and protective).Bioassay results revealed that some compounds exhibit high anti-TMV activities.The inactivation,curative and protective activites of compound 4n(43.5%,40.1%,38.7%)are superior to ribavirin and lead compound L2.The inactivation activities of compounds 4d(40.8%)and 4f(42.0%)are higher than that of ribavirin(38.6%)and lead compound L2(40.5%).The inactivation activity of compound 4I(38.4%)is equivalent to ribavirin(38.6%).The protective activity of compound 4f(36.4%)is equivalent to ribavirin(37.2%).Compound 4n is expected to become a potential antiviral pesticide.
