Their structures were characterized by melting points, 1H nuclear magnetic resonance(IH NMR) and high-resolution mass spectrometry(HRMS). The bioassay tests indicate that their insecticidal activities were weak to moderate. Antibacterial tests indicate that some of the compounds showed favourable activity in vitro against Physa- lospora piricola, Alternaria solani, Cercospora arachidicola, Gibberella sanbinetti and Phytophthora infestans at a dosage of 50 mg/L.展开更多
