General description
A cell-permeable, water-soluble phenanthridinone-derivative that acts as a potent inhibitor of poly(ADP-ribose) polymerase (PARP; EC50 = 20 nM). Shown to be about 10,000 times more potent than the prototypical PARP inhibitor, 3-Aminobenzamide (Cat. No. 165350; EC50 = 200 µM). Does not act as an antioxidant at higher concentrations (1 µM to 10 mM). Exhibits neuroprotection in in vivo and in vitro models of stroke. Also available as a 20 mM solution in H2O(Cat. No. 528151).
A water-soluble phenanthridinone-derivative that acts as a potent anti-inflammatory agent and an inhibitor of poly(ADP-ribose) polymerase (PARP; EC50 = 20 nM). Shown to be about 10,000-fold more potent than the prototypical PARP inhibitor, 3-Aminobenzamide (Cat. No. 165350) (EC50 = 200 µM). Suppresses neutrophil infiltration and nitric oxide production in peritonitis. Does not act as an antioxidant even at higher concentrations (1 µM to 10 µM). PJ34 inhibits peroxynitrite-induced cell necrosis with an (EC50 = 20 nM). Exhibits neuroprotective effects in in vivo and in vitro models of stroke.

In recent years, new therapies have been developed based on molecules that target molecular mechanisms involved in both the initiation and maintenance of the oncogenic process. Among these molecules are the poly(ADP-ribose) polymerase 1 (PARP1) inhibitors. PARP1 has emerged as

Stroke prognosis is negatively associated with an elevation of serum bilirubin, but how bilirubin worsens outcomes remains mysterious. We report that post-, but not pre-, stroke bilirubin levels among inpatients scale with infarct volume. In mouse models, bilirubin increases neuronal

Mass spectrometry-enabled ADP-ribosylation workflows are developing rapidly, providing researchers a variety of ADP-ribosylome enrichment strategies and mass spectrometric acquisition options. Despite the growth spurt in upstream technologies, systematic ADP-ribosyl (ADPr) peptide mass spectral annotation methods are lacking. HCD-dependent ADP-ribosylome studies
