Abstract
Marine natural products have attracted more and more attention in drug research and development due to their unique structure, diverse biological activities, and novel mode of action. Using antiviral alkaloid aldisine as the lead compound and drawing on the hydrogen bond effect widely used in drug design, derivatives containing oxime and hydrazone moieties were designed and synthesized by introducing functional groups with hydrogen-bond receptors or donors into molecules. The configuration of derivatives was systematically studied through nuclear Overhauser effect (NOE) spectroscopy and single crystal analysis. The antiviral activity test result showed that most derivatives had antiviral activity against tobacco mosaic virus (TMV), and some compounds had better activity than the commercial antiviral drug ribavirin, especially compounds 2 and 24, which had comparable activity to the most effective commercial antiviral drug ningnanmycin. Preliminary mode of action studies showed that compound 2 could affect the assembly of rod-shaped TMVs by promoting the aggregation and fragmentation of TMV coat proteins. Molecular docking experiments demonstrated that the introduction of oxime and hydrazone moieties could indeed increase the hydrogen bond between molecules and target proteins. In addition, we conducted fungicidal and larvicidal activities study of these derivatives. Most of these derivatives had good larvicidal activities against Mythimna separata and Plutella xylostella and showed broad-spectrum fungicidal activities.

Abstract
Based on the widespread use of hydrogen bonds in drug design, a series of aldisine derivatives containing oxime, oxime ether, and hydrazone moieties were designed and synthesized, and their antiviral, larvicidal, and fungicidal activities were evaluated for the first time. The bioassay results showed that most of these derivatives were active against tobacco mosaic virus (TMV). Hydrazone derivative 12 showed in vivo inactivation, curative, and protection activities of 52 ± 4, 49 ± 1, and 52 ± 3% at 500 mg/L, which are comparable to that of the commercial antiviral drug ningnanmycin (57 ± 3, 56 ± 2, and 59 ± 1%, respectively) at the same dose. The antiviral mechanism study showed that compound 12 could cause 20S CP (coating protein) disk fusion and disintegration, thus affecting the assembly of virus particles. The result of molecular docking indicated that there were obvious hydrogen bonds between compound 12 and TMV CP. Most derivatives were active against larvae of lepidopteran pests, such as Mythimna separata, Pyrausta nubilalis, and Plutella xylostella. Some compounds also exhibited larvicidal activities against Culex pipiens; among them compounds 9 and 13 exhibited larvicidal activities of 0.81 and 1.54 mg/L (LC50), respectively. Moreover, most of the derivatives showed broad-spectrum fungicidal activities against 14 kinds of phytopathogenic fungi at 50 mg/L.
