Phenotypic screening identifies a new oxazolone inhibitor of necroptosis and neuroinflammation.

ABSTRACT: Necroptosis is a regulated form of necrosis, which may be critical in the pathogenesis of neurodegenerative diseases. Neuroinflammation, characterized by the activation of glial cells such as microglia, is closely linked with neurodegenerative pathways and constitutes a major mechanism of neural damage and disease progression. Importantly, inhibition of necroptosis results in disease improvement, unveiling an alternative approach for therapeutic intervention. In the present study, we screened a small library of new molecules, potentially inhibitors of necroptosis, using two cellular models of necroptosis. A new oxazolone, Oxa12, reduced tumour necrosis factor α (TNF-α)-induced necroptosis in mouse L929 fibrosarcoma cells. Notably, Oxa12 strongly inhibited zVAD-fmk-induced necroptosis in mu
