A series of bis(indolyl)-hydrazide-hydrazone derivatives were synthesised, and their structures were characterised using H-NMR and HRMS. The antifungal activity of the prepared compounds was evaluated against Cav., Penz., Pers.: Fr. and Kühn using the mycelial growth rate method. The preliminary bioassays revealed that most of the synthesised compounds exhibited antifungal activity against the four tested fungi and displayed a remarkable inhibitory effect on the mycelium growth of . In particular, compounds 3b, 3c, and 3k demonstrated significant antifungal activity against , with EC values of 26.42, 20.74, and 22.41 μM, respectively, outperforming the positive control shenqinmycin (47.18 μM) and carvacrol (49.13 μM).
合成了一系列双(吲哚基)-酰肼腙衍生物,并使用氢核磁共振(H-NMR)和高分辨质谱(HRMS)对其结构进行了表征。采用菌丝生长速率法,对所制备化合物针对辣椒疫霉(Phytophthora capsici Leonian)、稻瘟病菌(Magnaporthe oryzae (T.T. Hebert) Barr)、核盘菌(Sclerotinia sclerotiorum (Lib.) de Bary)和禾谷镰刀菌(Fusarium graminearum Schwabe)的抗真菌活性进行了评估。初步生物测定表明,大多数合成化合物对四种受试真菌均表现出抗真菌活性,并对稻瘟病菌的菌丝生长显示出显著的抑制作用。特别是,化合物3b、3c和3k对稻瘟病菌表现出显著的抗真菌活性,其半数效应浓度(EC)值分别为26.42、20.74和22.41μM,优于阳性对照申嗪霉素(47.18μM)和香芹酚(49.13μM)。
