摘 要:設計合成了9個(gè)N-(1,4-取代吡唑-5-基)-1,2,3-噻二唑酰胺類(lèi)化合物,測試了化合物對小麥赤霉病菌(Gibberella zeae)、辣椒枯萎病菌(Fusarium oxysporum)和蘋(píng)果腐爛病菌(Cytospora mandshurica)的抑制活性。初步結果表明,目標化合物在50 μg/mL濃度下對小麥赤霉病菌、辣椒枯萎病菌和蘋(píng)果腐爛病菌有一定的抑制作用,其中化合物8j對小麥赤霉病菌的抑制率達到47.6%,接近對照藥劑惡霉靈;化合物8d對蘋(píng)果腐爛病菌的抑制率達到56.8%,與對照藥劑惡霉靈相當,具有進(jìn)一步研究的價(jià)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. |
