Abstract BACKGROUND To find efficient agricultural fungicides, 29 new 4‐thioquinazoline‐containing acetohydrazide derivatives were prepared and tested for their fungicidal properties. RESULTS All of the target compounds characterized by 1 H 13 C nuclear magnetic resonance high‐resolution mass spectrometry techniques, molecular structure compound A2 was verified single‐crystal X‐ray diffraction measurement. The experimental results revealed that many from this series had impressive inhibition efficacies in vitro against fungi. For example, A25 identified as best agent Rhizoctonia solani with an EC 50 (half‐maximal effective concentration) value 0.66 μg mL −1 , superior to those commercial fungicides chlorothalonil, carbendazim boscalid. Additionally, displayed favorable protection curative activities vivo rice sheath blight caused R . Antifungal mechanistic studies on indicated exerted its strong anti ‐R effects probably through fungal succinate dehydrogenase activity [half‐maximal inhibitory concentration (IC ) = 4.88 μ m ] impairment cell membrane integrity, based enzymatic bioassays, docking studies, scanning transmission electron microscopy observations.

With fungal diseases posing a major threat to agricultural production, the application of fungicides control related is often considered necessary ensure world's food supply. The search for new bioactive agents has long been priority in crop protection due continuous development resistance against currently used types active compounds. Heterocyclic compounds are an inseparable part core structures numerous lead compounds, these rings constitute pharmacophores significant number developed over past decade by agrochemists. Among heterocycles, nitrogen-based play essential role. To date, diazole (imidazole and pyrazole) diazine (pyrimidine, pyridazine, pyrazine) derivatives make up important series synthetic fungicides. In recent years, many reports have published on design, synthesis, study fungicidal activity scaffolds, but there was lack comprehensive classified review nitrogen-containing scaffolds. Regarding this issue, here we reviewed articles families. current review, molecules synthesized so far based size ring.

Oxysterol binding protein (OSBP) is a new target for oomycide development. To find more fungicidal active compounds targeting OSBP, series of carboxamides containing spiropiperidinyl-α-methylene-γ-butyrolactone and heterocyclic carboxylic acids were rationally designed synthesized by using computer-aided pesticide design method. The in vitro bioassay found that compound 5o showed broad-spectrum activity with EC50 values falling between 0.50 20.85 μg/mL against Phytophthora capsici Fusarium verticillioides, respectively, which was potent than 7c natural lead xanthatin. Compound also 44% vivo efficacy Pseudoperonospora cubensis, even at concentration 0.5 μg/mL. Fluorescence quenching microscale thermophoresis determination suggested bound to Osh4p stronger interactions oxathiapiprolin. RNA sequencing analysis discovered the ergosterol (ERG) gene cluster ribosome biogenesis eukaryotes downregulated. as good candidate OSBP deserving further studies.

Lepidopteran species cause significant harm to agricultural yields and food quality. In this study, a series of innovative isoxazoline derivatives incorporating pyrazolamide moieties were carefully designed synthesized as potential insecticidal agents. Among these, compound F16 demonstrated an LC50 value 0.01 mg/L against Plutella xylostella, surpassing that the lead fluxametamide (LC50 = 0.15 mg/L). Furthermore, exhibited broad-spectrum activity Pyrausta nubilalis, Spodoptera frugiperda, Chilo suppressalis, Aphis craccivora, Sogatella furcifera. Notably, possessed low toxicity Danio rerio, whereas displayed moderate toxicity. molecular docking analysis potent is likely mediated by its specific interactions with γ-GABA receptors primarily through formation hydrogen bonds key residues. Density functional theory calculations electrostatic potentials also performed gain insights into behavior F16. These findings suggest promising candidate for further investigation novel pesticide.

Abstract A series of novel 3‐(6‐methyltriazinone)‐3,4‐dihydrobenzo[ b ][1,5]diazin‐2(1 H )‐one derivatives was designed and synthesized as conformationally restricted analogues insecticide pymetrozine. Conformational physicochemical properties analyses indicated the rationality in reducing energy barrier between lowest‐energy predicted bioactive conformations, well pesticide‐likeness. Insecticidal bioassays showed that optimal compound VI‐6b exhibited a mortality rate 67.7% against Aphis craccivora at 400 mg L −1 . The molecular docking study within Nilaparvata lugens TRPV channel elucidated binding mode, wherein forms hydrogen bonds with Arg646 Glu727, while engaging π‐π interactions Phe688. However, revealed low lipophilicity poor aqueous solubility limited insecticidal efficacy these compounds. This provides valuable insights for future design insecticides targeting channel.
