摘　　要：以紫苏醛结构为母体,设计合成了12个肟醚类化合物,其中6个为未见文献报道的化合物,并通过~1H-NMR、C-NMR和ESI-MS对其结构进行了表征。经体外抑菌活性数据表明,3C对白色假丝酵母和痤疮丙酸杆菌的MIC分别为800μg·mL^(-1)、250μg·mL^(-1),抑菌活性优于紫苏醛(1.200mg·mL^(-1)和0.740mg·mL^(-1))。化合物3C和6C对白色假丝酵母抑菌活性强于阳性对照药氟康唑。分子对接结果表明化合物与蛋白结合形成氢键、疏水作用和π-π共轭,从而增强抑菌活性。Twelve oxime ether compounds were designed and synthesized by using perillaldehyde as starting material,among them,six compounds were unreported in literature.Their structures were characterized by~1H-NMR、C-NMR and ESI-MS.The antibacterial activity data showed that The MIC values of 3 C against candida albicans and propionibacterium acnes were 800μg·mL^(-1)and 250μg·mL^(-1),respectively,which were stronger than that of perillaldehyde(1.200 mg·mL^(-1)and 0.740 mg·mL^(-1)).The antibacterial activities of compounds 3 C and 6 C against candida albicans were stronger than those of fluconazole.According to the results of molecular docking,compound established hydrogen bonds,hydrophobic interactions,andπ-πconjugates with protein,which improved their antibacterial activity.
