Clear solution	5%DMSO 1 40%PEG300 2 5%Tween80 3 50%ddH2O	5.0mg/ml	Taking the 1 mL working solution as an example, add 50 μL of 100 mg/ml clarified DMSO stock solution to 400 μL of PEG300, mix evenly to clarify it; add 50 μL of Tween80 to the above system, mix evenly to clarify; then continue to add 500 μL of ddH2O to adjust the volume to 1 mL. The mixed solution should be used immediately for optimal results.
Clear solution	5% DMSO 1 95% Corn oil	0.65mg/ml	Taking the 1 mL working solution as an example, add 50 μL of 13 mg/ml clear DMSO stock solution to 950 μL of corn oil and mix evenly. The mixed solution should be used immediately for optimal results.

* <1 mg/ml means slightly soluble or insoluble.
* Please note that Selleck tests the solubility of all compounds in-house, and the actual solubility may differ slightly from published values. This is normal and is due to slight batch-to-batch variations.
* Room temperature shipping (Stability testing shows this product can be shipped without any cooling measures.)

Biological Activity

Description	Lefamulin (BC-3781), is a pleuromutilin antibiotic, inhibits protein synthesis by binding to the peptidyl transferase center of the 50S bacterial ribosome. It is effective against a range of gram-positive pathogens involved in community-acquired bacterial pneumonia (CABP), including Streptococcus pneumoniae, Haemophilus influenzae, Mycoplasma pneumoniae, Legionella pneumophila, Chlamydophila pneumoniae, Staphylococcus aureus (including methicillin-resistant and vancomycin-intermediate strains), and vancomycin-resistant Enterococcus faecium.
