Biological Activity

MS645 is a BET bromodomains (BrD) inhibitor for K of BRD4-BD1/BD2i The value is 18.4 nM. MS645 spatially limits the divalent inhibition of BRD4 BrDs, resulting in sustained inhibition of BRD4 transcriptional activity in solid tumor cells.

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.
