    PJ34 purchased from MedChemExpress. Usage Cited in: Nat Aging. 2024 May 9. [Abstract]

    Customer Validation
     IMR-90 human fibroblasts were incubated with the indicated death inhibitor or vehicle for 2 h, followed by H2O2 treatment (1 mM). Cell survival was measured using an MTS assay 24 h after 1 h H2O2 treatment of cells. The results showed that PJ34 (10 µM; pretreated for 2 h before applying H2O2) protected cells from oxidative stress-induced death, while no rescue was observed for other death inhibitors such as QVD (apoptosis), necrosulfonamide (necroptosis), ferrostatin-1 (ferroptosis), VX-765 (pyroptosis), pepstatin A (cathepsin D and E-induced death) and E64d (cathepsin B and L-induced, and calpain-induced death).

    Customer Validation
     IMR-90 human fibroblasts were incubated with the indicated death inhibitor or vehicle for 2 h, followed by H2O2 treatment (1 mM). Cells were stained for PAR polymers after 15 min H2O2 exposure; n = 152 from three independent experiments. Quantification was performed on single cells with images taken from multiple microscopic fields of view. The results showed that cells exposed toH2O2 showed a strong nuclear poly-ADP-ribose (PAR) signal that was significantly suppressed by PJ34 (10 µM; pretreated for 2 h before applying H2O2), indicating an on-target effect of the inhibitor. Scale bar, 150 µm.

    Customer Validation
     IMR-90 human fibroblasts were incubated with the indicated death inhibitor (PJ34 (10 µM)) or vehicle for 2 h, followed by H2O2 treatment (1 mM). Fourteen days after treatment cells were analyzed using quantitative PCR with reverse transcription (RT–qPCR) for expression of the indicated mRNAs relative to the housekeeping gene (tubulin); n = 6.

    Customer Validation
     Immunofluorescence staining with TOM20 and endogenous HK-II of IMR-90 cells pretreated with vehicle or PJ34 exposed to H2O2 (1 mM); control, n = 94, H2O2 and H2O2 +  PJ34 (10 µM; pretreated for 2 h before applying H2O2), n = 87 from three independent experiments, Scale bar, 10 µm. The results showed that incubation with PJ34 in cells exposed to H2O2 was sufficient to retain the mitochondrial pool of HK-II.

    Customer Validation
     Mice underwent unilateral kidney IRI with the administration of the PARP inhibitor PJ34 (10 mg/kg) or vehicle. Three days after induction of IRI, kidney tissues were collected for histological and molecular analysis. Periodic acid–Schiff staining was used to detect the necrotic area (defined by a red line), n = 5 for vehicle-treated and n = 6 for PJ34-treated mice. Scale bar, 100 µm. The results showed that IRI was characterized by an increased necrotic area, which was considerably reduced by PJ34 treatment.
