MedKoo CAT#: 406128

CAS#: 344458-15-7 (HCl)

Description: PJ-34 is a novel and potent PARP-1 inhibitor with potential anticancer activity. PJ34 has a high affinity for PARP-1 (IC(50) = 20 nM). PJ-34 inhibits PARP-1 expression and ERK phosphorylation in glioma-conditioned brain microvascular endothelial cells. PJ-34 reduces mesenteric vascular injury induced by experimental cardiopulmonary bypass with cardiac arrest. PJ-34 reduce cell inflammation and damage that follow PARP-1 overexpression. PJ-34 negatively modulate proinflammatory commitment of human glioblastoma cells.
