Conversion of different model animals based on BSA (PMID: 27057123)
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 Compound A used for a mouse (20 mg/kg) to a dose based on the BSA for a rat, multiply 20 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 Compound A of 10 mg/kg.

Astressin 2B

Astressin 2B is a potent and selective corticotropin-releasing factor receptor 2 (CRF2) antagonist, with the IC50 values of 1.3 nM and > 500 nM for CRF2 and CRF1, respectively.


Deutivacaftor is a potentiator that improves the flow of salt and water across cell membranes by increasing the probability of channel opening of CFTR proteins delivered to the cell surface.Deutivacaftor can be used in cystic fibrosis (CF) related studies.


Vanzacaftor is a cystic fibrosis transmembrane conductance regulator (CFTR) corrector that increases the number of CFTR proteins on the cell surface by facilitating the processing and transport of CFTR proteins, and can be used in cystic fibrosis (CF) related studies.
