金黄色葡萄球菌是导致皮肤和脆弱组织疾病的主要原因,从浅表皮肤到
深部侵袭性感染等多种临床重要感染都和金黄色葡萄球菌有关(T. Horino.; S.Hori. Metastatic infection during Staphylococcus aureus bacteremia. J. Infect. Chemother. 2020, 26 (2), 162-169.,S. Gatadi.; J. Gour.; S. Nanduri.Natural product derived promising anti-MRSA drug leads: A review. Bioorg. Med. Chem. 2019, 27, 3760-3774.)。由于长期和过量使用抗生素,金黄色葡萄球
菌可以通过多种机制避免抗菌药物的作用,对其治疗的选择构成严重障碍,已成为威胁21世纪全球的主要医疗问题之一,(H. L. Qin.; J. Liu.; W.Y. Fang.; L.Ravindar.; K.P. Rakesh. Indole-based derivatives as potential antibacterialactivity against methicillin-resistance Staphylococcus aureus (MRSA). Eur. J. Med. Chem. 2020, 194, 112245; Y. G. Cong.; S.J. Yang.; X.C. Rao. Vancomycinresistant Staphylococcus aureusinfections: a review of case updating andclinical features. J. Adv. Res. 2020, 21, 169-176.; X. Zhi. 1,2,3-Triazole-containing hybrids with potential antibacterial activity against methicillin-resistant Staphylococcus aureus (MRSA). Eur. J. Med. Chem. 2020, 206,112686.)迫切需要开发新型抗菌剂。

将样品用DMSO配成溶液后加到滤纸片上,每片含药量为200 µg。将
滤纸片分别贴于涂布了细菌(大肠杆菌、金黄色葡萄球菌)的固体平板上,于孵化箱内37 ℃培养24-36 h,记录实验结果,以盐酸环丙沙星作为阳性对照,以抑菌圈直径(单位:mm)的大小表示样品抑菌活性的大小,实验重复三次,抑菌结果取其平均值。
通过以上实验证实本发明的如通式Ⅰ所示化合物对金黄色葡萄球菌具有很强的抑菌活性,抑制作用超过了阳性对照,因此该类化合物可用于临床使用的新型抑菌药物。
本发明取得的有益效果是:
