analysis. By using the mycelium growth rate method, the compounds were evaluated for antifungal activities in vitro against six plant pathogenic fungi, and structure-activity relationships (SAR) were derived. Almost all of the compounds showed obvious inhibition activity on each of the fungi at 150 muM. For all of the fungi, 10 of the compounds showed average inhibition rates of >80% at 150 muM, and

生物,并通过光谱分析对其进行了表征。通过使用菌丝体生长速率方法,评估了这些化合物在体外对六种植物病原真菌的抗真菌活性,并推导了结构-活性关系(
SAR)。几乎所有化合物在150μM时对每种真菌均表现出明显的抑制活性。对于所有真菌,其中的10种化合物在150μM时显示出平均抑制率> 80%,并且大多数
EC50值在2.0-30.0μM的范围内。
SAR分析表明,N-芳基环的取代方式显着影响活性。N9烷基化可提高活性,而C环的芳构化则可降低活性。
