Biological Activity

ARB-272572 is a potent small molecule PD-L1 inhibitor that inhibits the PD-1/PD-L1 axis by inducing cell-surface PD-L1 dimerization via a cis-interacting homodimer with an IC50 value of 400 pM.

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.
