Biological Activity

KPT-9274, also known as PAK4-IN-1, is a potent, selective and dual PAK4/NAMPT inhibitor with IC50s less than 100 and 120 nM, respectively. KPT-9274 interferences with PAK4/NAMPT signaling pathways, which results in reduction of G2-M transit as well as induction of apoptosis and decrease in cell invasion and migration in several human RCC cell lines. KPT-9274 demonstrated the expected on-target effects in this mouse model. KPT-9274 (oral administation; 100mg/kg or 200 mg/kg; twice a day; 14 days) demonstrates a decrement of xenograft growth and exists no significant weight loss in animals receiving KPT-9274. 8 hours after, KPT-9274 are measured at the end of the experiment in mouse plasma and tumors with 10757 ng/ml and 10647 ng/ml, respectively.

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 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.
