Neospiramycin I is a macrolide antibiotic that targets bacterial ribosomes, inhibiting protein synthesis. It demonstrates significant antibacterial activity against macrolide-sensitive strains of Staphylococcus aureus, with a minimum inhibitory concentration (MIC) of 3.12 µg/mL, and exhibits effectiveness against various Gram-positive bacteria, including Bacillus cereus and Bacillus subtilis, along with Gram-negative bacteria such as Escherichia coli and Klebsiella pneumoniae, at MIC values ranging from 0.2 to 50 µg/mL. In vivo, Neospiramycin I protects mice in a type III S. pneumoniae infection model, with an effective dose 50 (ED50) of 399.8 mg/kg, making it a valuable tool for studies on bacterial resistance and antibiotic efficacy.
