WZ811 is a highly potent competitive antagonist of CXCR4. WZ811 shows subnanomolar potency (EC50 = 0.3 nM) in an affinity binding assay. WZ811 inhibits CXCR4/stromal cell-derived factor-1 (SDF-1)-mediated modulation of cyclic adenosine monophophate (cAMP) levels (EC50 = 1.2 nM). In addition, WZ811 efficiently inhibits SDF-1 induced Matrigel invasion (EC50 = 5.2 nM).

For example, to modify the dose of resveratrol used for a mouse (22.4 mg/kg) to a dose based on the BSA for a rat, multiply 22.4 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 resveratrol of 11.2 mg/kg.
