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 A11 exhibited 100% inhibition rates. In addition, the molecular docking results indicated that both compound A10 and A11 interacts
摘要设计合成了一系列含取代吡唑的色酮衍生物。初步的生物测定表明,大多数合成的化合物在体内对10 mg / L的根结线虫都有良好的杀线虫活性。在测试的化合物中,A10和A11表现出100%的抑制率。此外,分子对接结果表明,化合物A10和A11都通过氢键和π-π堆积与AChE的氨基酸残基Tyr121,Trp279,Tyr70,Trp84和Phe330相互作用。这项研究表明,可以进一步优化含有色酮的取代吡唑支架,以探索新型的,具有高生物活性的杀线虫剂。
