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.

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
