PJ34 hydrochloride
PJ34 is a novel and potent inhibitor of poly(ADP-ribose) polymerase (PARP), an enzyme involved in DNA repair and cell proliferation, that dose-dependently inhibits purified PARP enzyme in a cell-free assay with half maximal effective concentration EC50 value of 20 nM. Unlike other PARP inhibitors (such as 3-AB), PJ34 does not possess any antioxidant properties but exhibits 10,000 times greater PARP inhibition than 3-AB (EC50 = 200 μM). PJ34 has been found to have neuro-protective effects and enhance the chemotherapeutic effects in several tumor types. Study results have shown that PJ34 inhibits peroxynitrite-induced cell necrosis with EC50 value of 20 nM and dose-dependently suppresses the growth of HepG2 cells.
