The unreasonable use or long-term use of a single variety of pesticide has led to drug resistance and made the pesticides ineffective. Therefore, the creation of new, efficient, and low-risk pesticides is imminent. Marine natural products play a vital role in serving as new lead compounds. In this work, we realized the efficient preparation of nine marine sesquiterpenes with the Stork–Danheiser reaction as the key step and designed and synthesized a series of their derivatives. The antiviral activity and antifungal activity research showed that these compounds exhibited good to excellent biological activities. Compounds 7b and 8e displayed significantly higher antiviral activities against tobacco mosaic virus (TMV) than ribavirin and could be used as new antiviral candidates. The antiviral mode of action research indicated that compound 8e inhibited the formation of the 20S protein disk by acting on the TMV coat protein and therefore inhibited the assembly of TMV particles. This work provides a new idea for the development of new pesticides based on marine sesquiterpenes.

用于植物保护的海洋倍半萜：发现 Laurene 倍半萜及其衍生物作为新型抗病毒和抗植物病原真菌剂
不合理使用或长期使用单一品种的农药，导致产生耐药性，使农药失效。因此，开发新型、高效、低风险的农药迫在眉睫。海洋天然产物作为新的先导化合物发挥着至关重要的作用。在这项工作中，我们以Stork-Danheiser反应为关键步骤实现了九种海洋倍半萜的高效制备，并设计合成了一系列衍生物。抗病毒活性和抗真菌活性研究表明，这些化合物具有良好的生物活性。化合物7b和8e对烟草花叶病毒 (TMV) 的抗病毒活性显着高于利巴韦林，可用作新的抗病毒候选药物。抗病毒作用模式研究表明，化合物8e通过作用于TMV外壳蛋白抑制20S蛋白盘的形成，从而抑制TMV颗粒的组装。该工作为开发基于海洋倍半萜的新型农药提供了新思路。
