To further explore the structure-activity relationship(SAR) of amide bridge moeity of anthranilic diamides derivatives, a series of N -pyridylpyrazole derivatives was designed, synthesized and their biological activities were evaluated. The chemical structures of novel target compounds were confirmed by 1 H nuclear magnetic resonance (NMR), 13 C NMR and elemental analyses(EA). Bioassay results of insecticidal activity demonstrated that the target compound 6 h displayed 70% lethality rate against oriental armyworms at 200 mg/L. Moreover, most compounds displayed moderate to excellent antifungicidal activities against Fusarium oxysporum f. sp . cucumerinum , Cercospora arachidicola Hori , Botryosphaeria dothidea , Alternaria solani , Gibberella zeae and Phytophthora capsici at 50 mg/L. In particular, compound 6 e showed 61.5% and 92.3% inhibition rate against Cercospora arachidicola Hori and Botryosphaeria dothidea , which was superior to the commercial positive control Chlorothalonil . These results will provide a potential clue for exploring novel high-effective agrochemicals.
