![عکس صفحه اول مقاله: Synthesis and antimicrobial activity of amide derivatives of polyether antibiotic—salinomycin Synthesis and antimicrobial activity of amide derivatives of polyether antibiotic—salinomycin](/preview/png/1369623.png)
For the first time a direct and practical approach to the synthesis of eight amide derivatives of polyether antibiotic—salinomycin is described. The structure of allyl amide (3a) has been determined using X-ray diffraction. Salinomycin and its amide derivatives have been screened for their in vitro antimicrobial activity against the typical Gram-positive cocci, Gram-negative rods and yeast-like organisms, as well as against a series of clinical isolates of methicillin-resistant Staphylococcus aureus and methicillin-sensitive S. aureus. Amides of salinomycin have been found to show a wide range of activities, from inactive at 256 μg/mL to active with MIC of 2 μg/mL, comparable with salinomycin. As a result, phenyl amide (3b) was found to be the most active salinomycin derivative against Gram-positive bacteria, MRSA and MSSA.
