Tertiary amides of Salinomycin: A new group of antibacterial agents against Bacillus anthracis and methicillin-resistant Staphylococcus epidermidis.

For the first time, a series of tertiary amides of polyether antibiotic-Salinomycin have been obtained and screened for their antibacterial activity against different strains of bacteria, including Bacillus anthracis and clinical methicillin-resistant Staphylococcus epidermidis (MRSE). Moreover, biofilm inhibition of MRSE and genotoxicity tests against Bacillus subtilis have been performed. Our studies show that Salinomycin and its some derivatives are active against tested bacteria and exhibited definitely bacteriostatic, not bactericidal activity.
