Biological Activity

Lefamulin (BC-3781) acetate is a pleuromutilin class of antimicrobial agent, inhibits bacterial protein synthesis by selectively binding to the peptidyl transferase center of the bacterial ribosome, prevents the correct positioning of the 3′-CCA ends of tRNAs for peptide transfer.
Lefamulin (BC-3781) exhibits a log-normal MIC distribution against the population of S. pneumoniae, with modal MIC, MIC50, and MIC90 results of 0.12, 0.12, and 0.25 μg/ml, respectively.
Lefamulin (BC-3781) exhibits potent antibacterial activity against the most important respiratory and skin pathogens, including Streptococcus spp. and Staphylococcus spp., fastidious Gram-negative organisms, such as Haemophilus influenzae, and atypical respiratory pathogens, including Mycoplasma pneumoniae, Chlamydophila pneumoniae, and Legionella pneumophila.
