Customer Product Validations & Biological Datas
Source Arterioscler Thromb Vasc Biol (2013). Figure 3. KRP-203
Method i.v.
Cell Lines LDL-R-/- mice
Concentrations 3.0 mg/kg
Incubation Time 16 weeks
Results In addition, reduced production of interleukin (IL)-2 and interferon (IFN)-γ, 2 cytokines released from activated CD4+ T cells in response to concanavalin A or phytohaemagglutinin, was noted in splenocytes obtained from KRP-203–treated mice
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.
