Product Information
Description: Lefamulin acetate (Xenleta, BC-3781 acetate) is a pleuromutilin antibiotic for community-acquired bacterial pneumonia (CABP) treatment. Lefamulin acetate inhibits protein synthesis by binding to the peptidyl transferase center of the 50S bacterial ribosome, thus preventing the binding of transfer RNA for peptide transfer.
   
Stability and Solubility Advice: Information concerning product stability, particularly in solution, has rarely been reported and in most cases we can only offer a general guide.
We recommend that stock solutions, once prepared, are stored aliquoted in tightly sealed vials and used within 1 month. Avoid repeated freeze and thaw cycles. Storage conditions for some special products should refer to their storage details.
