Biological Activity

Antibacterial Solithromycin binds to the large 50S subunit of the ribosome and inhibits protein biosynthesis. The mean 50% inhibitory concentrations (IC50s) for Solithromycin inhibition of cell viability, protein synthesis, and growth rate were 7.5, 40, and 125 ng/ml for Streptococcus pneumoniae,Staphylococcus aureus, and Haemophilus influenzae, respectively.

Cell Experiment
Cell lines S. aureus cells
Preparation method For S. pneumoniae, 12 9-ml cultures of cells comprised of one control set and one set with solithromycin at 7.5 ng/ml were grown to a Klett reading of 15.
Concentrations 7.5 ng/ml
Incubation time 15-min
Animal Experiment
Animal models donor mic
Formulation DMSO
Dosages 100 mg/kg
Administration i.v.
Conversion of different model animals based on BSA (Value based on data from FDA Draft Guidelines)
Species Mouse Rat Rabbit Guinea pig Hamster Dog
Weight (kg) 0.02 0.15 1.8 0.4 0.08 10
Body Surface Area (m2) 0.007 0.025 0.15 0.05 0.02 0.5
Km factor 3 6 12 8 5 20
Animal A (mg/kg) = Animal B (mg/kg) multiplied by  Animal B Km
Animal A Km

For example, to modify the dose of resveratrol used for a mouse (22.4 mg/kg) to a dose based on the BSA for a rat, multiply 22.4 mg/kg by the Km factor for a mouse and then divide by the Km factor for a rat. This calculation results in a rat equivalent dose for resveratrol of 11.2 mg/kg.
