PARP [1]
(Cell-free assay)
20 nM(EC50)
In vitro

PJ34 is a potent, phenanthridinone PARS inhibitor, which is approximately 10,000 times more potent than the prototypical PARS inhibitor 3-aminobenzamide. PJ34 inhibited peroxynitrite-induced cell necrosis with EC50 of 20 nM. PJ34 provides cardioprotection by decreasing myocardial infarct size and enhancing postischemic regional and global functional recovery. [1]

In vivo PJ34 suppresses the development of clinical signs of EAE in MBP-immunized PLSJL mice. PJ34 exerted therapeutic effects at the onset of EAE that are associated with reduced CNS inflammation and the maintenance of neurovascular integrity. PJ34 partially inhibits the expression of TNF-α and ICAM-1 in the Spinal Cord Tissues of MBP-Immunized Mice.[2] PJ34 provides significant, dose-dependent, anti-inflammatory effects in a variety of local inflammation models. PJ34 dose-dependently suppresses neutrophil infiltration and nitric oxide (but not KC and IL-1β) production in peritonitis. In a model of systemic endotoxemia, PJ34 pretreatment significantly reduces plasma levels of TNF-α, IL-1β and nitrite/nitrate (breakdown products of nitric oxide) production. PJ34 treatment (oral gavage) induces a significant suppression of the inflammatory response in dextran sulfate colitis, multiple low dose streptozotocin diabetes and cyclophosphamide-accelerated autoimmune diabetes in the non-obese diabetic mice, and reduces the degree of mononuclear cell infiltration into the iris in an endotoxin-induced uveitis model.

Method for preparing DMSO master liquid: mg drug pre-dissolved in μL DMSO ( Master liquid concentration mg/mL, Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug. )

Method for preparing in vivo formulation: Take μL DMSO master liquid, next addμL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH2O, mix and clarify.

Method for preparing in vivo formulation: Take μL DMSO master liquid, next add μL Corn oil, mix and clarify.

Note: 1. Please make sure the liquid is clear before adding the next solvent.
2. Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such
as vortex, ultrasound or hot water bath can be used to aid dissolving.
