摘 要:设计合成了9个N-(1,4-取代吡唑-5-基)-1,2,3-噻二唑酰胺类化合物,测试了化合物对小麦赤霉病菌(Gibberella zeae)、辣椒枯萎病菌(Fusarium oxysporum)和苹果腐烂病菌(Cytospora mandshurica)的抑制活性。初步结果表明,目标化合物在50 μg/mL浓度下对小麦赤霉病菌、辣椒枯萎病菌和苹果腐烂病菌有一定的抑制作用,其中化合物8j对小麦赤霉病菌的抑制率达到47.6%,接近对照药剂恶霉灵;化合物8d对苹果腐烂病菌的抑制率达到56.8%,与对照药剂恶霉灵相当,具有进一步研究的价值。

Abstract:A series of N-(1,4 disubstituted pyrazole-yl)-1,2,3-thiadiazole carboxamide derivatives were synthesized. All target compounds were bioassayed in vitro against three kinds of phytopathogenic fungi (Gibberella zeae,Fusarium oxysporum,Cytospora mandshurica). The results indicated that most of the synthesized compounds possessed antifungal activities to a certain extent,among which compound 8d displayed 56.8% inhibition against C. mandshurica at 50 μg/mL,and compound 8j displayed 47.6% inhibition against G. zeae at 50 μg/mL. The structures of the target compounds could be further optimized based on the designed compounds.
