Biological Activity

Tosedostat (CHR2797) is an aminopeptidase inhibitor with IC50 of 100, 150, 220, <1000, <5000, <10000 and <30000 nM for LAP, PuSA, aminopeptidase N, aminopeptidase B, PILSAP, LTA4 hydrolase and MetAP2, respectively. It has demonstrated anti-tumour activity in a number of models of cancer, both as a single agent and in synergy with cytotoxic agents such as carboplatin and paclitaxel.

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.
