Biological Activity

BMS-582949 inhibits both p38 kinase activity and activation of p38. BMS-582949 treatment of cells in which p38 has been activated by LPS rapidly reversed p38 activation as shown by loss of phosphorylation of p38. BMS-582949 binding to p38a results in a conformational change of the activation loop which is phosphorylated by upstream kinases, therefore it inhibits phosphorylation of p38 by upstream MKK by inducing a less accessible conformation of the activation loop. 

In vivo, the mouse clearance rate for BMS-582949 is 4.4 mL/min/kg. BMS-582949 exhibited oral bioavailability values of 90% and 60% in mice and rats, 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.
