TRAF2 protects against cerebral ischemia-induced brain injury by suppressing necroptosis.

Necroptosis contributes to ischemia-induced brain injury. Tumor necrosis factor (TNF) receptor associated factor 2 (TRAF2) has been reported to suppress necroptotic cell death under several pathological conditions. In this study, we investigated the role of TRAF2 in experimental stroke using a mouse middle cerebral artery occlusion (MCAO) model and in vitro cellular models.

Synthesis and biological evaluation of novel hydrogen sulfide releasing nicotinic acid derivatives.

Twelve novel hybrids of slowly releasing hydrogen sulfide donor ADT-OH combined with nicotinic acid were synthesized. All of their structures had been confirmed by H NMR, C NMR and MS spectra. The target compounds were evaluated for their neuroprotective effects on hippocampal neuron HT22 cells against glutamate-induced injury at the concentrations of 1-100μM with MTT assay, and their toxicity on HT22 cells untreated by glutamine at the concentration of 100μM.
