Sphingosine-1-phosphate is a endogenous second messenger involved in the control of cell proliferation and motility, and Ca2+ mobilization. Acts as an agonist at sphingosine-1-phosphate receptors (S1P1-5) and as an activator of GPR3, GPR6 and GPR12. Effectors regulated include p38 MAP kinase, PLC, adenylyl cyclase, myosin light chain phosphatase and focal adhesion kinase.

|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.
