新型二氢异喹啉酮类化合物及其作为制备抗植物病原真菌杀 菌剂的应用Novel dihydroisoquinolinone compounds and their application in the preparation of anti-plant pathogenic fungicides

技术领域Technical Field

本发明涉及农药领域和植物保护领域,尤其是新型二氢异喹啉酮类化合物及其作为制备抗植物病原真菌杀菌剂的应用。The invention relates to the field of pesticides and plant protection, in particular to novel dihydroisoquinolinone compounds and applications thereof in preparing anti-plant pathogenic fungicide.

背景技术Background Art

植物病原真菌是导致农作物减产欠收的主要因素之一,并且其分泌的多种代谢产物具有严重的毒副作用,已严重威胁粮食安全。由于农作物抗性品种匮乏、生物防治见效缓慢,化学杀菌剂仍是防治农作物真菌病害的主要手段。然而,随着化学杀菌剂的长期大量使用,农药残留、真菌的抗药性等问题日益暴露,亟需创制新型的绿色农药用以防治植物真菌病害,保障粮食安全。Plant pathogenic fungi are one of the main factors leading to crop yield reduction and poor harvest, and the various metabolites they secrete have serious toxic side effects, which have seriously threatened food security. Due to the lack of crop resistant varieties and the slow effectiveness of biological control, chemical fungicides are still the main means of preventing and controlling fungal diseases of crops. However, with the long-term and large-scale use of chemical fungicides, problems such as pesticide residues and fungal resistance have become increasingly exposed. There is an urgent need to create new green pesticides to prevent and control plant fungal diseases and ensure food security.

异喹啉酮类生物碱是自然界中一类常见的含氮杂环天然产物,主要分布于罂粟科、石蒜科、防己科等植物。异喹啉酮类生物碱结构类型多样,具有显著的生物活性,如具有强效抗癌活性的水鬼蕉碱,抗肿瘤活性的水仙环素等。近年来,围绕异喹啉酮类生物碱的结构优化和生物活性筛选一直是新药开发的重点。另外,异喹啉酮骨架也是构成药物分子的重要活性单元,存在于多种医药分子和农药化学品中。基于前期研究结果,申请人采用仿生合成策略,以异喹啉酮为活性母核,通过药效团拼接和生物电子等排的原理,设计并合成了一系列结构新颖的二氢异喹啉酮类化合物。结果证明,本发明中所涉及的二氢异喹啉酮类化合物对多种植物病原真菌具有抑菌活性。Isoquinolinone alkaloids are a common type of nitrogen-containing heterocyclic natural products in nature, mainly distributed in plants such as Papaveraceae, Amaryllidaceae, and Menispermaceae. Isoquinolinone alkaloids have diverse structural types and significant biological activities, such as aquabine with strong anticancer activity and narcissin with antitumor activity. In recent years, the structural optimization and biological activity screening of isoquinolinone alkaloids have always been the focus of new drug development. In addition, the isoquinolinone skeleton is also an important active unit that constitutes drug molecules and exists in a variety of pharmaceutical molecules and pesticide chemicals. Based on the results of previous studies, the applicant adopted a biomimetic synthesis strategy, using isoquinolinone as the active parent nucleus, and designed and synthesized a series of novel dihydroisoquinolinone compounds through the principle of pharmacophore splicing and bioisostericity. The results show that the dihydroisoquinolinone compounds involved in the present invention have antibacterial activity against a variety of plant pathogenic fungi.

本发明所涉及的新型二氢异喹啉酮类化合物都为未见文献报道的新化合物。本专利是申请人首次对此类二氢异喹啉酮类化合物的抗植物病原真菌活性报道。The novel dihydroisoquinolinone compounds involved in the present invention are all new compounds that have not been reported in the literature. This patent is the first report by the applicant on the anti-plant pathogenic fungi activity of such dihydroisoquinolinone compounds.

The compound is dissolved in DMSO to prepare a 10 mg/mL solution, and diluted with 0.5% Tween 20 to a test solution with a concentration of 1 mg/mL. Take 0.75mL of the above test solution and add it to a 45mL centrifuge tube. Then add PDA medium to 15mL while it is hot. Pour it into a culture dish after mixing evenly. After cooling and solidification, inoculate the test bacteria. Use an equal amount of test solution without the target compound as a blank control. Each group was cultured in an inverted manner at 25±1℃ for 3 times in parallel. The average value was taken when the results were statistically analyzed. The colony diameter was measured using the cross method. The results of the anti-plant pathogenic fungi test are shown in Table 2.
