Lefamulin acetate

Catalog No. T11836Cas No. 1350636-82-6
Alias BC-3781 acetate

Lefamulin acetate (BC-3781 acetate) (formally BC-3781 acetate) is a novel pleuromutilin antibiotic and is the first to be used for the systemic treatment of bacterial infections in humans. Lefamulin acetate (BC-3781 acetate) inhibits protein synthesis by binding to the peptidyl transferase center of the 50S bacterial ribosome, preventing the binding of transfer RNA for peptide transfer. Lefamulin acetate (BC-3781 acetate) is an orally active antibiotic for community-acquired bacterial pneumonia (CABP) treatment.

In vitro
Lefamulin has activity against gram-negative organisms, including Haemophilus influenza (MIC50=1 μg/ml; MIC90=0.12 μg/ml) and Moraxella cotarrhali (MIC50=2 μg/ml; MIC90=0.25 μg/ml)[1].Lefamulin acetate (BC-3781 acetate) has activity against the resistant gram-postive organisms, including taphylococcus aureus (MRSA) (MIC50=0.12 μg/ml; MIC90=0.25 μg/ml); β-Hemolytic strepococcus (MIC50=0.03 μg/ml; MIC90=0.03 μg/ml); Viridans group Streptococcus (MIC50=0.12 μg/ml; MIC90=0.5 μg/ml), Enterocossus faecium (MIC50=0.12 μg/ml; MIC90=4 μg/ml), Streptococcus pneumonia (MIC50=0.12 μg/ml; MIC90 =0.25 μg/ml)[1].

In Vivo Formulation Calculator (Clear solution)

Please enter your animal experiment information in the following box and click Calculate to obtain the mother liquor preparation method and in vivo formula preparation method:
TargetMol | Animal experimentsFor example, your dosage is 10 mg/kg Each animal weighs 20 g, and the dosage volume is 100 μL . TargetMol | Animal experiments A total of 10 animals were administered, and the formula you used is 5% TargetMol | reagent DMSO+30% PEG300+5% Tween 80+60% ddH2O. So your working solution concentration is 2 mg/mL。
Mother liquor preparation method: 2 mg of drug dissolved in 50 μL DMSOTargetMol | reagent (mother liquor concentration of 40 mg/mL), if you need to configure a concentration that exceeds the solubility of the product, please contact us first.
Preparation method for in vivo formula: Take 50 μL DMSOTargetMol | reagent main solution, add 300 μLPEG300TargetMol | reagent mix well and clarify, then add 50 more μL Tween 80, mix well and clarify, then add 600 more μLddH2OTargetMol | reagent mix well and clarify
For Reference Only. Please develop an appropriate dissolution method based on your laboratory animals and route of administration.
