Biological Activity

NXY-059 is a free radical-trapping neuroprotectant that has been reported to reduce infarct size and preserve brain function in experimental models of acute ischemic stroke. NXY-059-treated animals significantly reduced the loss of hemispheric tissue compared to brain-injured controls (43.0 +/- 11 mm3 versus 74.4 +/- 19 mm3, respectively; p < 0.01). NXY-059 significantly attenuated the loss of injured brain tissue and improved cognitive outcome, suggesting a major role for ROS in the pathophysiology of TBI. NXY-059 is now under the Phase 2 clinical trial in patients with prelapsed or refractory multiple myeloma.

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.
