Chemistry

Disufenton sodium is the disulfonyl derivative of the neuroprotective nitrone spin trap phenylbutylnitrone or "PBN". PBN and its derivatives hydrolyze and oxidize in vitro to form respectively MNP-OH (AKA, NtBHA) and its parent spin-trap MNP.

Research

Disufenton sodium was under development at the drug company AstraZeneca. A 2005 phase-3 clinical trial^[4][5] 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".^[4] AstraZeneca then terminated the development programme.^[6]

Disufenton sodium has been researched as a potential treatment for use in brain tumors and cancers, including diffuse intrinsic pontine glioma (DIPG)^[7][8] and glioblastoma.^[9][10]

A compound (NHPN-1010) containing a combination of disufenton sodium and acetylcysteine has been researched as a potential treatment for tinnitus and hearing loss.^{[11][12][13][14]}
