Description

Technical Field

[0001] This invention belongs to the field of pharmaceutical synthesis technology, specifically relating to indothiazole derivatives and their synthesis methods and applications. Background Technology

[0002] Piercing-sucking and chewing pests, such as aphids, spider mites, and armyworms, are among the major pests affecting most crops in agriculture. However, due to the long-term and frequent use of pesticides, they have developed particularly serious resistance. Therefore, there is an urgent need to develop new and better insecticides.

[0003] Indanones are a class of organic compounds with an indenyl ring skeleton and a ketone carbonyl group on the ring. They are the core structural unit of many natural products and synthetic drugs. Their basic structure consists of a benzene ring coupled to a five-membered carbon ring with a carbonyl group (C=O), forming a rigid, planar fused ring system. Their basic structures mainly include 1-indanone, 2-indanone, as well as 1,2-indanedione, 1,3-indanedione, and ninhydrine, among others. Indanone structures are widely found in many natural products with significant biological activity. For example, many indanone compounds isolated from plants such as algae, mosses, vines, or microorganisms like Streptomyces have excellent inhibitory activity against the growth of human vascular endothelial factor and are used to regulate tumor angiogenesis. In addition, indanone structures are also found in synthetic drugs, pesticides, dyes, amino acid colorimetric reagents, and various fine chemicals. Indanones have distinctive structural features, especially 1-indanone. Due to its unique electron distribution and ring strain, it can serve as a substrate for reactions, and its carbonyl ortho position is also prone to enolization, thus possessing rich chemical reactivity and providing a basis for structural derivatization.

[0004] Thiazole compounds are a class of five-membered aromatic heterocyclic compounds containing nitrogen and sulfur atoms. Their unique electronic structure and molecular properties make them a "preferred backbone" in pesticide molecule design. The thiazole ring readily interacts with various targets in organisms through hydrogen bonds, van der Waals forces, and metal ion coordination, thus exhibiting a wide range of biological activities. Since Merck successfully developed the first thiazole fungicide, thiabendazole, in 1962, these compounds have rapidly become a research hotspot in the field of green pesticide creation due to their outstanding advantages, including low toxicity to humans and warm-blooded animals, high bioactivity, environmental friendliness, and easy degradation in the environment. Over the past sixty years, domestic and international pesticide research institutions have successfully developed dozens of commercialized thiazole pesticide varieties, covering multiple fields such as insecticides, fungicides, and herbicides. In terms of insecticides, there are neonicotinoids such as imidacloprid, thiamethoxam, thiamethoxam, and thiamethoxam, as well as thiazophos and flufenoxuron; in terms of fungicides, there are thifluzamide, thiazoxamide, bensulfuron-methyl, and seed dressing agents; in terms of herbicides, there are also safeners based on the thiazole structure and herbicides such as thiamethoxam.

[0005] This invention is based on the rational drug design concept of "active structural unit splicing," aiming to innovatively fuse the promising natural indanone skeleton with a highly efficient and mature thiazole pharmacophore. We hypothesize that the organic combination of the two can not only retain their original active characteristics, but also potentially generate novel mechanisms of action and biological activities that transcend single structures through structural complementarity and synergistic effects.

[0409] Example 2: Study on the biological activity of indomethacin derivatives against wheat aphids, spider mites, and armyworms.

[0410] (1) Experiment on the effect of indomethacin derivatives on wheat aphid activity

[0411] The inhibitory activity of the indomethacin derivatives listed in Table 1 against aphids was determined using the slide immersion method. Specific method: A certain amount of the test compound was accurately weighed and dissolved in acetone. A solution with a concentration of 100 μg / mL was prepared by adding 0.1% Tween-80 aqueous solution. The solution was allowed to stand at room temperature for half an hour until completely dissolved before storage. The aphids and branches were immersed in the prepared solution for 5 seconds, then removed and blotted dry with absorbent paper. Thiamethoxam was used as the positive control, and 0.1% Tween-80 aqueous solution was used as the negative control. After 48 hours of humidified culture in petri dishes, the mortality rate was observed. The results are shown in Table 1.

[0420] (3) Experiment on the effect of indomethacin derivatives on the activity of *Armoria spp.*

[0421] The third instar larvae of the Eastern armyworm were used as test insects in a 24-hour starvation experiment. Chlorfenapyr was used as a positive control. The activity was determined using the leaf-dish method. In the initial screening stage, the test samples were prepared as 500 μg / mL / acetone solutions, and the control agent chlorfenapyr was prepared as a 100 μg / mL / acetone solution. Fresh wheat leaves were cut into 5 mm × 5 mm square pieces and immersed in the prepared solution for 5 s. Subsequently, after the acetone had evaporated, the leaf-dish pieces were added to the wells of a 24-well plate containing third instar larvae of the Eastern armyworm, one leaf-dish per well and one test insect per well. Each sample was tested in triplicate, with 12 test insects per group. Leaves treated with acetone served as blank controls. The number of live armyworms was recorded after 48 h, and the mortality rate was calculated. The results are shown in Table 3.
