Plant diseases seriously endanger plant health, and it is very difficult to control them. A series of nortopsentin analogues were designed, synthesized, and evaluated for their antiviral activities and fungicidal activities. Most of these compounds displayed higher antiviral activities than ribavirin. Compounds 1d, 1e, and 12a, with excellent antiviral activities, emerged as novel antiviral lead compounds
植物病害严重危害植物健康,很难控制。设计,合成和评估了一系列降钙素原类似物的抗病毒活性和杀真菌活性。这些化合物大多数显示出比病毒唑更高的抗病毒活性。具有优异抗病毒活性的化合物1d,1e和12a出现为新型抗病毒先导化合物,其中1e被选择用于进一步的抗病毒机制研究。机制研究结果表明,这些化合物可能通过聚集病毒颗粒来阻止其在植物中的移动,从而发挥抗病毒作用。进一步的杀真菌活性测试表明,降钙素原类似物具有广谱杀真菌活性。与商业杀菌剂多菌灵和百菌清相比,化合物2p和2f表现出更高的抗黑斑病菌的抗真菌活性。当前的研究为降钙素原类似物在植物保护中的应用奠定了基础。
