Novel acylurea derivatives 7a-7ab were designed and synthesized by linking the active substructures trifluoromethylpyridine and anthranilic diamide via an acylurea bridge. Most of the title compounds exhibited good activity against tobacco mosaic virus (TMV), particularly compound 7x (EC50 of 211.8 μg/mL), which showed much higher curative activity than ningnanmycin (EC50 of 389.8 μg/mL), and compound 7ab, which showed excellent inactivation activity (EC50 of 36.1 μg/mL), similar to ningnanmycin (EC50 of 23.2 μg/mL). The preliminary mechanism of these derivatives was investigated. Autodocking analysis revealed that compounds 7x and 7ab had good affinity for TMV coat protein (TMV CP), with low binding energies (-7.86 and -8.59 kcal/mol) comparable to ningnanmycin (-8.75 kcal/mol). Molecular dynamics simulation showed that compound 7x had a stable system structure with a better binding free energy (-32.94 kcal/mol) than ningnanmycin (-25.62 kcal/mol). Microscale thermophoresis showed that compound 7x bound more strongly to TMV CP (Kd of 19.8 ± 7.3 μM) than ningnanmycin (Kd of 21.2 ± 7.3 μM). Transmission electron microscopy and self-assembly experiments demonstrated that compounds 7x and 7ab significantly obstructed the self-assembly of TMV RNA and TMV CP. This new acylurea derivative has excellent antiviral activity by targeting TMV CP and inhibiting TMV self-assembly and can be considered a candidate for antiviral applications.

A series of novel phenylpyrazole carboxylic acid derivatives containing fluorine moiety, i.e., diamides 11, simple aryl-bearing amides 12 and acylthioureas 14 were successfully synthesized based on the key fluoro-containing phenylpyrazole acid intermediate. The new compounds were identified and confirmed by melting point, 1H NMR, 13C NMR and elemental analysis or HRMS. The bioassay results indicated that some of the compounds possessed excellent insecticidal activities towards oriental armyworm, diamondback moth and corn borer at low concentrations. For examples, compounds 11a, 11e?g and 14b exhibited remarkable larvicidal activities with LC50 values of 0.13 ? 0.39 mg/L and 0.0002 ? 0.0014 mg/L against oriental armyworm and diamondback moth, respectively, were comparable with those of the control chlorantraniliprole. Particularly, 11e were found superior to chlorantraniliprole in oriental armyworm tests (LC50: 0.23 mg/L vs. 0.26 mg/L); 11a, 11e, 11f and 14c in diamondback moth tests with LC50 values of 0.0002 mg/L, 0.0002 mg/L, 0.0008 mg/L and 0.0005 mg/L, respectively, were more effective than that of chlorantraniliprole. In addition, 12a also showed a promising insecticidal potential and development/optimization advantage. Compounds 11a, 11e–g, 12a, 14b and 14c could be considered as possible new leading structures for further study. The SAR investigation indicated that the compounds with fluorine motif (e.g., -F, -CF2H, -CF3) held apparently favorable insecticidal potentials, which provided useful guidance for further design/development of new phenylpyrazole-containing agrochemicals.

A series of novel 1,2,3-benzotriazin-4-one derivatives containing 4,5-dihydrothiazole-2-thiol were synthesized and characterized by 1H NMR, 13C NMR, 19F NMR and HRMS. The bioassay results showed that compounds 3-(3-((4,5-dihydrothiazol-2-yl)thio)propyl)-7-methoxybenzo[d][1–3]triazin-4(3H)-one, 3-(3-((4,5-dihydrothiazol-2-yl)thio)propyl)-6-nitrobenzo[d][1–3]triazin-4(3H)-one, 7-chloro-3-(3-((4,5-dihydrothiazol-2-yl)thio)propyl)benzo[d][1–3]triazin-4(3H)-one exhibited good control efficacy against the cucumber root-knot nematode disease caused by Meloidogyne incognita at the concentration of 10.0 mg L?1 in vivo. Compound 7-chloro-3-(3-((4,5-dihydrothiazol-2-yl)thio)propyl)benzo[d][1–3]triazin-4(3H)-one showed excellent nematicidal activity with inhibition 68.3% at a concentration of 1.0 mg L?1. It suggested that the structure of 1,2,3-benzotriazin-4-one containing 4,5-dihydro-thiazole-2-thiol could be optimized further.

To explore new skeleton with nematicidal activity, a series of novel 1,2,3-benzotriazin-4-one derivatives containing piperazine as linker were synthesized and varied fragments were also introduced to increase structure diversity of the new skeleton. Their inhibitory activities in vivo were evaluated against Meloidogyne incognita. The newly prepared compounds A6, A8, A21, A28 and A38 exhibited more than 50% inhibition at the concentration of 20 mg/L. Especially compound A6 displayed 71.4% inhibition against Meloidogyne incognita at the concentration of 20 mg/L. The nematicidal activities varied significantly depending on the types and positions of the substituents, which provided guidance for further structure modification.
