A series of chromone derivatives containing substituted pyrazole were designed and synthesized. Preliminary bioassays showed that most of the synthesized compounds exhibited good nematicidal activity in vivo against Meloidogyne incognita at 10 mg/L. Among the tested compounds, A10 and All exhibited 100% inhibition rates. In addition, the molecular docking results indicated that both compound A10 and All interacts with amino acid residue Tyr121, Trp279, Tyr70, Trp84 and Phe330 of AChE via hydrogen bond and pi-pi stacking. This investigation suggested that the chromone containing substituted pyrazole scaffold could be further optimized to explore novel, high-bioactivity nematicidal leads.
