Disufenton sodium (NXY-059, Cerovive) is the disulfonyl derivative of the neuroprotective spin trap phenylbutylnitrone or "PBN". It was under development at the drug company AstraZeneca. A 2005 phase-3 clinical trial[1][2] called "SAINT-1" reported some efficacy in the acute treatment of ischemia injury due to stroke. However, a 2006 attempt to repeat this trial indicated no significant activity. After ruling out other causes, the authors tentatively attributed the positive results in the first trial to "chance".[1] AstraZeneca then terminated the development programme.[3] PBN and its derivatives hydrolyze and oxidize in vitro to form respectively MNP-OH ( AKA, NtBHA ) and its parent spin-trap MNP.
