The synthesis of Yanglingmycin and its enantiomer, along with eighteen Yanglingmycin analogues is reported. The structures were confirmed mainly by analyses of NMR spectral data. Antibacterial activity assays showed that Yanglingmycin and some of its analogues exhibited significant antibacterial activities against two important agricultural pathogenic bacteria, Ralstonia solanacearum and Pseudomonas syringae pv. actinidiae, with minimum inhibitory concentration (MIC) values ranging from 3.91 to 15.62 µg/mL. The antibacterial activities exhibited by Yanglingmycin and its analogues are promising, suggesting potential in the development of compounds for novel bactericides.
报告了阳灵霉素及其对映体,以及十八种阳灵霉素类药物的合成。其结构主要通过核磁共振(NMR)光谱数据的分析得以确认。抗菌活性测定表明,阳灵霉素及其部分类药物对两种重要的农业病原菌——苏云金芽孢杆菌(Ralstonia solanacearum)和青枯病细菌(Pseudomonas syringae pv. actinidiae)具有显著的抗菌活性,最低抑菌浓度(MIC)值范围为3.91至15.62 µg/mL。阳灵霉素及其类药物表现出的抗菌活性具有潜力,建议在新型杀菌剂的化合物开发中具有应用前景。
