Biological Activity

Razuprotafib (AKB-9778) is an effective selective inhibitor of ve-PTP (HPTPß) catalytic activity (IC50=17 pM), which promotes TIE2 activation, enhances ANG1-induced TIE2 activation, and stimulates phosphorylation of signal molecules in TIE2 pathway. Including AKT, eNOS, and ERK. Razuprotafib inhibited structure-related phosphatase PTP1B with an IC50 of 780 nM. Besides HPTPη (IC50=36 pM) and HPTPγ (100 pM), Razuprotafib showed good selectivity to VE-PTP.

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.
