Biological Activity

Description NXY-059 (Cerovive, Disufenton Sodium) is a novel nitrone, shows efficacious neuroprotective effects. Phase 3.
In vitro

NXY-059 is more soluble than the spin trapping agent α-phenyl-N-tert-butyl nitrone (PBN). [1] In an in vitro blood-brain barrier (BBB) model, 250 mM of NXY-059 administered at the onset or up to 4 h after oxygen glucose deprivation (OGD) produces a significant reduction in the increased BBB permeability caused by OGD. Furthermore, OGD produces a huge influx of tissue plasminogen activator across the BBB, which is substantially reduced by NXY-059. [2]

In vivo NXY-059 reduces infarct volume in rats subjected to 2 hours of middle cerebral artery occlusion in a dose-dependent manner. At equimolar doses (3.0 mg/kg for NXY-059 and 1.4 mg/kg for PBN), NXY-059 is more efficacious than PBN. Similar results are obtained when a recovery period of 7 days is allowed. The window of therapeutic opportunity for NXY-059 is 3 to 6 hours after the start of recirculation. [1] NXY-059, a free radical-trapping agent, has a substantial protective effect, lessening the disability caused by an experimentally induced stroke in a primate species. NXY-059 treatment reduces the overall amount of brain damage by >50% of saline-treatment values, with similar levels of protection afforded to both white and gray matter. [3] Treatment with NXY-059 (50 mg/kg subcutaneous plus 8.8 mg/kg/h for 3 days subcutaneous delivered via implanted osmotic pumps) significantly decreases neurological impairment following intracerebral hemorrhage in rat, and reduces the neutrophil infiltrate observed 48 hours post-hemorrhage in the vicinity of the hematoma, and the number of TUNEL-positive cells 48 hours post-hemorrhage at the hematoma margin.

Method for preparing DMSO master liquid: mg drug pre-dissolved in μL DMSO ( Master liquid concentration mg/mL, Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug. )

Method for preparing in vivo formulation: Take μL DMSO master liquid, next addμL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH2O, mix and clarify.

Method for preparing in vivo formulation: Take μL DMSO master liquid, next add μL Corn oil, mix and clarify.

Note: 1. Please make sure the liquid is clear before adding the next solvent.
2. Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such
as vortex, ultrasound or hot water bath can be used to aid dissolving.
