Abstract
Pesticides play an important role in the development of agriculture, as they can prevent and control crop diseases and pests, improve crop yield and quality. However, the abuse and improper use of pesticides can lead to negative impacts such as environmental pollution and pest resistance issues. There is an urgent need to develop green, safe, and efficient pesticides. In this work, natural product arecoline was selected as parent structure, a series of arecoline derivatives were designed, synthesized, and systematically investigated antiviral activities against tobacco mosaic virus (TMV). These compounds were found to have good to excellent anti-TMV activities for the first time. The antiviral activities of 4a, 4 h, 4 l, 4p, 6a, 6c, and 6f are higher than that of ningnanmycin. Compounds 4 h (EC50 value 146 µg/mL) and 4p (EC50 value 161 µg/mL) with simple structures and excellent activities emerged as new antiviral candidates. We chose 4 h to further investigate the antiviral mechanism, which revealed that it can cause virus fragmentation by acting on the viral coat protein (CP). We further validated this result through molecular docking. These compounds also displayed broad-spectrum fungicidal activities against 8 plant pathogenic fungi. This work lays the theoretical foundation for the application of arecoline derivatives in the agricultural field.

Abstract
Derivatives of morpholine are biologically active organic compounds with special structures discovered in multiple drugs. As a result of the terminal pharmacophore of action and extraordinary activity, they attracted fair attention with regard to pesticide innovation and development. Analysis of brief structure-activity relationships and the summarization of the characteristics of pesticides containing morpholine fragments with efficient activity are key steps in the development of novel pesticides. This review primarily overviews morpholine compounds with insecticidal, fungicidal, herbicidal, antiviral, and plant growth regulation properties to provide educational insight for the creation of new morpholine-containing compounds.

Abstract
Multidrug resistance (MDR) caused by ATP-Binding Cassette Subfamily B Member 1 (ABCB1, P-glycoprotein, P-gp) is a major barrier for the success of chemotherapy in clinics. In this study, we designed and synthesized a total of 19 Lissodendrins B analogues and tested their ABCB1-mediated MDR reversal activity in doxorubicin (DOX)-resistant K562/ADR and MCF-7/ADR cells. Among all derivatives, compounds D1, D2, and D4 with a dimethoxy-substituted tetrahydroisoquinoline fragment possessed potent synergistic effects with DOX and reversed ABCB1-mediated drug resistance. Notably, the most potent compound D1 merits multiple activities, including low cytotoxicity, the strongest synergistic effect, and effectively reversing ABCB1-mediated drug resistance of K562/ADR (RF = 1845.76) and MCF-7/ADR cells (RF = 207.86) to DOX. As a reference substance, compound D1 allows for additional mechanistic studies on ABCB1 inhibition. The synergistic mechanisms were mainly related to the increased intracellular accumulation of DOX via inhibiting the efflux function of ABCB1 rather than from affecting the expression level of ABCB1. These studies suggest that compound D1 and its derivatives might be potential MDR reversal agents acting as ABCB1 inhibitors in clinical therapeutics and provide insight into a design strategy for the development of ABCB1 inhibitors.

Abstract
Pesticides are essential for the development of agriculture. It is urgent to develop green, safe and efficient pesticides. Bisindole alkaloids have unique and concise structures and broad biological activities, which make them an important leading skeleton in the creation of new pesticides. In this work, we synthesized bisindole alkaloid barakacin in a simple seven-step process, and simultaneously designed and synthesized a series of its derivatives. Biological activity research indicated that most of these compounds displayed good antiviral activities against tobacco mosaic virus (TMV). Among them, compound 14b exerted a superior inhibitory effect in comparison to commercially available antiviral agent ribavirin, and could be expected to become a novel antiviral candidate. Molecular biology experiments and molecular docking research found that the potential target of compound 14b was TMV coat protein (CP). These compounds also showed broad-spectrum anti-fungal activities against seven kinds of plant fungi.

Abstract
Fungal and viral diseases account for 70-80% of agricultural production losses caused by microbial diseases. Synthetic fungicides and antiviral agents have been used to treat plant diseases caused by plant pathogenic fungi and viruses, but their use has been criticized due to their adverse side effects. As alternative strategies, natural fungicides and antiviral agents have attracted many researchers' interest in recent years. Herein, we designed and synthesized a series of novel polycarpine simplified analogues. Antiviral activity research against tobacco mosaic virus (TMV) revealed that most of the designed compounds have good antiviral activities. The virucidal activities of 4, 6d, 6f, 6h, and 8c are higher than that of polycarpine and similar to that of ningnanmycin. The structure simplified compound 8c was selected for further antiviral mechanism research which showed that compound 8c could inhibit the formation of 20S protein discs by acting on TMV coat protein. These compounds also displayed broad-spectrum fungicidal activities against 7 kinds of plant fungi. This work lays the foundation for the application of polycarpine simplified analogues in crop protection.

Abstract
Plant virus diseases, also known as “plant cancers”, cause serious harm to the agriculture of the world and huge economic losses every year. Antiviral agents are one of the most effective ways to control plant virus diseases. Ningnanmycin is currently the most successful anti-plant virus agent, but its field control effect is not ideal due to its instability. In recent years, great progress has been made in the research and development of antiviral agents, the mainstream research direction is to obtain antiviral agents or lead compounds based on structural modification of natural products. However, no antiviral agent has been able to completely inhibit plant viruses. Therefore, the development of highly effective antiviral agents still faces enormous challenges. Therefore, we reviewed the recent research progress of anti-plant virus agents based on natural products in the past decade, and discussed their structure-activity relationship (SAR) and mechanism of action. It is hoped that this review can provide new inspiration for the discovery and mechanism of action of novel antiviral agents.

Abstract
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.

Abstract
With the increasing severity of plant diseases and the emergence of pathogen resistance, there is an urgent need for the development of new efficient and environment-friendly pesticides. Marine natural product (MNP) resources are rich and diverse. Structural simplification based on MNPs is an important strategy to find novel pesticide candidates. In this work, the marine natural product 6″-debromohamacanthin A (1a) was efficiently prepared and selected as the parent structure. A series of hamacanthin derivatives were designed, synthesized, and studied on the antiviral and antifungal activities. Most of these compounds displayed higher antiviral activities than ribavirin. The antiviral activities of compounds 1a and 13e-13h are similar to or higher than that of ningnanmycin (perhaps the most efficient anti-plant-virus agent). Compound 13h was selected for further antiviral mechanism research via transmission electron microscopy, molecular docking, and fluorescence titration. The results showed that compound 13h could bind to TMV CP and interfere with the assembly process of TMV CP and RNA. In addition, these hamacanthin derivatives also exhibited broad-spectrum inhibitory effects against eight common agricultural pathogens. Compounds 1a, 12b, and 12f with excellent fungicidal activities can be considered as new fungicidal candidates for further research. These results provide a basis for the application of hamacanthin alkaloids in crop protection.

Abstract
New diseases are emerging as the environment changes, so drug manufacturers are always on the lookout for new resources to develop effective and safe drugs. In recent years, many bioactive substances have been produced in the marine environment, which represents an alternative resource for new drugs used to combat major diseases such as cancer or inflammation. Many marine-derived medicinal substances are in preclinical or early stage of clinical development, and some marine drugs have been put on the market, such as ET743 (Yondelis®). This review presents the sources, activities, mechanisms of action and syntheses of bioactive substances based on marine natural products in clinical trials and on the market, which is helpful to understand the progress of drug research by application of marine natural products.

Abstract
Plant diseases have been threatening food production. Controlling plant pathogens has become an important strategy to ensure food security. Although chemical control is an effective disease control strategy, its application is limited by many problems, such as environmental impact and pathogen resistance. In order to overcome these problems, it is necessary to develop more chemical reagents with new functional mechanisms. Due to their special living environment, marine organisms have produced a variety of bioactive compounds with novel structures, which have the potential to develop new fungicides. In the past two decades, screening marine bioactive compounds to inhibit plant pathogens has been a hot topic. In this review, we summarize the screening methods of marine active substances from plant pathogens, the identification of marine active substances from different sources, and the structure and antibacterial mechanism of marine active natural products. Finally, the application prospect of marine bioactive substances in plant disease control was prospected.

Abstract
Plant diseases are seriously endangering agricultural production. The emergence of drug resistance has brought great challenges to the prevention and control of plant diseases. There is an urgent need for the emergence of new drug candidates. In this work, we achieved the efficient synthesis of pulmonarins A and B in 64% and 59% overall yield, respectively. Pulmonarins A and B were found to have good antiviral activities against tobacco mosaic virus (TMV) for the first time. A series of pulmonarin derivatives were designed, synthesized, and evaluated for their antiviral and fungicidal activities systematically. Most compounds displayed higher anti-TMV activities than commercial ribavirin. Compounds 6a, 6c, and 6n with better inactivation effects than ningnanmycin emerged as new antiviral candidates. We selected 6c for further antiviral mechanism research, which revealed that it could inhibit virus assembly by interacting with TMV coat protein (CP). The molecular docking results further confirmed that these compounds could interact with CP through hydrogen bonding. These compounds also displayed broad spectrum fungicidal activities. Especially compound 6u with prominent antifungal activity emerged as a new fungicidal candidate for further research. The current work provides a reference for understanding the application of pulmonarin alkaloids in plant protection.

Marine-natural-products for biocides development: first discovery of meridianin alkaloids as antiviral and anti-phytopathogenic-fungus agents. PEST MANAGEMENT SCIENCE 2020; 76:3369-3376. [PMID: 31756256 DOI: 10.1002/ps.5690] [Citation(s) in RCA: 10] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 08/12/2019] [Revised: 11/07/2019] [Accepted: 11/12/2019] [Indexed: 06/10/2023]
Abstract
BACKGROUND Food is an important strategic material related to national economy and people's livelihood. Plant diseases seriously affect crop yield and quality. Marine natural products are an important source for novel drugs discovery. In this work, meridianin alkaloids were selected as the parent structure. A series of meridianin alkaloid analogues were rationally designed, synthesized and evaluated for their antiviral activities and fungicidal activities. RESULT These compounds were found to have good antiviral and fungicidal activities for the first time. The structure-activity relationship (SAR) research revealed that introducing bromine atom at the 5-position of indole ring is beneficial to antiviral activity, but introducing methoxy group is not conducive. Introducing bromine atom at the 6-position of indole ring or nitrogen atom at the 7-position of the indole ring resulted in lower antiviral activity. Most of the meridianin derivatives showed higher anti-TMV activities at 500 μg mL-1 than Ribavirin, especially for compounds 6c, 8a and 10a. All of the compounds also displayed broad spectrum fungicidal activities against 14 kinds of phytopathogenic fungi at 50 μg mL-1 . CONCLUSION Compound 6c with relatively simple structure and excellent antiviral activity, which is similar to that of Ningnanmycin, emerged as novel anti-TMV lead compound. Compound 5d with broad spectrum and high effect fungicidal activity emerged as a new fungicidal lead compound. Current research lays a solid foundation for the application of meridianin alkaloids in crop protection. © 2019 Society of Chemical Industry.

Abstract
Plant diseases caused by plant viruses and pathogens seriously affect the production and storage of food crops. With the emergence of drug resistance, it is very difficult to control. Natural products are the source of new drug discovery. Here, the natural product streptindole was found to have good antiviral activity against tobacco mosaic virus (TMV) and fungicidal activities against 14 kinds of phytopathogenic fungi. A series of derivatives of streptindole were designed, synthesized, and evaluated for their antiviral and fungicidal activities. Compounds 4, 5, 11, 12c, 12d, 13d, and 13i-13l showed higher anti-TMV activities than ribavirin (inhibitory rate: 38, 37, and 40% at 500 μg/mL for inactivation, curative, and protection activity in vivo, respectively), among which compound 12d (inhibitory rate: 57, 55, and 53% at 500 μg/mL for inactivation, curative, and protection activity in vivo, respectively) with excellent antiviral activity was further evaluated for the mode of action. The mechanism research revealed that 12d can break the three-dimensional structure of TMV coat protein (CP) through hydrogen bonds, thus inhibiting the assembly of virus particles. The molecular docking result showed that compound 12d did exhibit strong interaction with TMV CP. The derivatives of streptindole also displayed broad-spectrum fungicidal activities. The current study provided valuable insights into the antiviral and fungicidal activities of streptindole derivatives.

Abstract
Previously, we reported for the first time that harmala alkaloids harmine and tetrahydroharmine exhibit activity against plant viruses, and we developed an analogue, designated NK0209, that efficiently prevents and controls plant virus diseases. Here, to investigate the influence of the spatial configuration of NK0209 on its antiviral activities, we synthesized its four optical isomers, determined their configurations, and evaluated their activities against tobacco mosaic virus. All four isomers were significantly more active than ningnanmycin, which is one of the most successful commercial antiviral agents, with in vivo inactivation, cure, and protection rates of 57.3 ± 1.9, 54.2 ± 3.3, and 55.0 ± 4.1% at 500 μg/mL. Furthermore, analysis of structure-activity relationships demonstrated for the first time that the spatial conformation of NK0209 is an important determinant of its antiviral activity, and our results provide information about the possible optimum configuration for interaction of this molecule with its target protein.

Abstract
Plant diseases seriously affect crop yield and quality and are difficult to control. Marine natural products (MNPs) have become an important source of drug candidates with new biological mechanisms. Marine natural product essramycin (1) was found to have good anti-tobacco mosaic virus (TMV) and anti-phytopathogenic fungus activities for the first time. A series of essramycin derivatives were designed, synthesized, and evaluated for their bioactivity. Most of these compounds exhibited antiviral effects that are greater than that of the control ribavirin. Compounds 7e and 8f displayed antiviral activities that are greater than that of ningnanmycin (the most widely used antiviral agent at present), thus emerging as novel antiviral lead compounds. As the lead compound, 7e was selected for further antiviral mechanism research. The results indicated that 7e could inhibit virus assembly and promote 20S disk protein aggregation. Fungicidal activity tests against 14 kinds of phytopathogenic fungi revealed that essramycin analogues displayed broad-spectrum fungicidal activities. Compound 5b displayed more than 50% inhibition rate against most of the 14 kinds of phytopathogenic fungi at 50 μg/mL. The current research lays a solid foundation for the application of essramycin alkaloids in crop protection.

Abstract
Lissodendrin B is a 2-aminoimidazole alkaloid bearing a (p-hydroxyphenyl) glyoxal moiety that was isolated from the Indonesian sponge Lissodendoryx (Acanthodoryx) fibrosa. We reported the first efficient total synthesis of Lissodendrin B. The precursor 4,5-disubstituted imidazole was obtained through Suzuki coupling and Sonogashira coupling reactions from 4-iodoimidazole. C2-azidation and reduction of the azide then provided the core structures of Lissodendrin B. Subsequent triple-bond oxidation, demethylation, and deacetylation gave the final product. The synthesis approach consists of ten steps with an overall yield of 1.1% under mild reaction conditions, and it can be applied for future analog synthesis and biological studies.

Abstract
Plant viral diseases cause tremendous decreases in crop yield and quality. Natural products have always been a valuable source for lead discovery in medicinal and agricultural chemistry. A series of pimprinine alkaloids and their derivatives were prepared and identified by nuclear magnetic resonance (NMR) spectroscopy and high-resolution mass spectrometry (HR-MS). The antiviral activities of these alkaloids against tobacco mosaic virus (TMV) were systematically investigated for the first time. Most of the compounds exhibited higher antiviral activities than ribavirin. Compounds 5l, 9h, and 10h, which had similar or higher antiviral activities than ningnanmycin (perhaps the most widely used antiviral agent at present), emerged as new antiviral pilot compounds. This systematic structure-activity-relationship research lays the foundation for simplifying the structure of these alkaloids. The ring-open products, acylhydrazones 9a-9u, were also found to possess good antiviral activities. Moreover, all the synthesized compounds displayed broad-spectrum fungicidal activities. This study provides important information for the research and development of pimprinine alkaloids as novel antiviral agents.
