the formation of alkylboronate esters and methane. Cyclic ethers are also amenable to catalytic hydroboronolysis. Mechanistic studies indicated the immediate in situ formation of a mono-hydridobridged dinuclear ruthenium complex [(η6-p-cymene)RuCl}2(μ–H−μ–Cl)] (2), which is highly active for hydroboronolysis of ethers. Over time, the dinuclear species decompose to produce ruthenium nanoparticles that

compounds characterized by the lowest minimum inhibitory concentration/minimum bactericidal concentration (MIC/MBC) values against H. pylori were also tested in order to verify a cytotoxic effect against AGS cells with respect to 5-fluorouracil and carvacrol. Three derivatives can be considered as new lead compounds alternative to current therapy to manage H. pylori infection, preventing the occurrence
在基于香芹酚的衍生物上采取类似的方法后,我们研究了针对八种幽门螺杆菌菌株的合成和微生物筛选,以及基于一系列结构的新型醚化合物对人胃腺癌(AGS)细胞的细胞毒活性。百里香酚。结构分析包括元素分析和1 H / 13 C / 19F NMR谱。在该分子库中对38种与结构相关的化合物进行的构效关系分析表明,百里酚OH基团的某些化学修饰导致所有分离物的广谱生长受到抑制。与烷基链相比,优选的取代基是苄基,并且在苄基部分对位的特定官能团(例如4-CN和4-Ph)的特定存在赋予了最低抑制浓度的所有菌株以最大的抗幽门螺杆菌活性(MIC)值高达4 µg / mL。苄基环上的多取代不是必需的。此外,几种化合物的特征在于针对幽门螺杆菌的最低最低抑菌浓度/最低杀菌浓度(MIC / MBC)值为了验证针对5-氟尿嘧啶和香芹酚的AGS细胞的细胞毒性作用,还测试了它们的含量。三种衍生物可被视为替代目前用于治疗幽门螺杆菌感
