标题:不同阳离子类型和烷基链长度的新型季铵盐和季鏻盐对抗耐药金黄色葡萄球菌的功效
摘要:抗菌素耐药性对公共卫生构成严重威胁,对细菌感染的预防和治疗提出了挑战.对创新抗菌剂的探索激发了人们对季杂鎓盐 (Qhs) 的浓厚兴趣,例如季铵和鏻化合物作为潜在的候选者.在这项研究中,合成了 49 个结构相关的 Qhs 库,不同的阳离子类型和烷基链长度.通过测定最低抑制/杀菌浓度 (Mic/mbc) <= 64 µg/ml 来评估它们对金黄色葡萄球菌(包括抗生素耐药菌株)的抗菌活性.结构-活性关系分析强调烷基三苯基鏻盐和烷基甲基咪唑盐对金黄色葡萄球菌 Cect 976 最有效.烷基侧链的长度显着影响抗菌活性,最佳链长度在 C10 和 C14 之间.对选定的 Qhs 的剂量反应关系进行了评估,显示出遵循非线性模式的剂量依赖性抗菌活性.生存曲线表明低浓度的 Qhs,特别是化合物 1E,3E 和 5E,可以有效根除金黄色葡萄球菌 Cect 976.此外,体外人体细胞数据表明,化合物 2E,4E 和

摘要:Provided are a solid catalyst which gives a cyclic carbonate at a high yield and a high selectivity, which is stable and which may be readily separated after reaction; and a method of industrially advantageous, inexpensive and safe production of a cyclic carbonate by the use of the catalyst. The catalyst contains an inorganic solid substance having a surface modified with an ionic substance containing a Group 15 element; or contains an ionic substance containing a Group 15 element, and an inorganic solid substance. The modifying group for surface modification of an inorganic solid substance is an ionic substance containing a Group 15 element. The ionic substance containing a Group 15 element is at least one substance selected from organic phosphonium salts, organic ammonium salts, organic arsonium salts and organic antimonium salts.
