Sodium fusidate

Methyl methacrylate (MMA, Alfa Aesar, Warsaw, Poland) and [2-(methacryloyl-oxy)ethyl]trimethylammonium chloride (TMAMA, 80% aq. solution, Sigma-Aldrich, Poznan, Poland) were dried using molecular sieves or under vacuum, respectively. Copper(I) chloride (CuCl, Fluka, 98%, Steinheim, Germany) was purged according to procedures described previously [39 (link)]. Methanol was obtained from Chempur (Piekary Śląskie, Poland). Rifampicin (RIF, 97%) and sodium fusidate (FUS, 98.8%) were purchased from Alfa Aesar (Warsaw, Poland) and used without prior purification. Phosphate-buffered saline (PBS), 2,2′-bipyridine (bpy), and tetrahydrofuran (THF) were obtained from Sigma-Aldrich (Poznań, Poland).

The methyl methacrylate (MMA; Alfa Aesar, Warsaw, Poland) was dried using molecular sieves (type 4Å, Chempur, Piekary Śląskie, Poland). The [2-(methacryloyloxy)ethyl]-trimethylammonium chloride (TMAMA/Cl; 80% aq. solution, Sigma-Aldrich, Poznań, Poland) was dried to a constant weight under reduced pressure. Methanol and tetrahydrofuran (THF) were purchased from Chempur (Piekary Śląskie, Poland) and dried over the same molecular sieves as MMA. Copper(I) bromide (CuBr; Fluka, 98%, Steinheim, Germany) was purified using a procedure described previously in the literature [42 (link)]. N,N,N′,N″,N″-pentamethyldiethylenetriamine (PMDETA, 98%), ethyl 2-bromoisobutyrate (EBiB, 98%), potassium clavulanate (KCLV), and bis(trifluoromethane)sulfonimide lithium salt (LiTf₂N) were obtained from Sigma Aldrich (Poznań, Polska). Sodium p-aminosalicylate (NaPAS, 98%), sodium piperacillin (NaPIP, 99%), and sodium fusidate (NaFUS, 98.8%) were purchased from Alfa Aesar (Warsaw, Poland) and used without further purification.
