产品描述

Poly (ADP-ribose) polymerase (PARP) 1 is an essential molecule in DNA damage response by sensing DNA damage and docking DNA repair proteins on the damaged DNA site through a type of posttranslational modification, poly (ADP-Ribosyl)ation (PARylation). PARP inhibitors, which inhibit PARylation through competitively binding to NAD+ binding site of PARP1 and PARP2, have improved clinical benefits for BRCA mutated tumors, leading to their accelerated clinical application. XAV-939 is a potent tankyrase inhibitor that targets Wnt/β-catenin signaling. XAV-939 stabilizes axin by inhibiting tankyrase 1 and tankyrase 2 (IC50s of 5 and 2 nM, respectively), thereby stimulating β-catenin degradation. XAV939 binds tightly to the catalytic (PARP) domains of TNKS1 and TNKS2 (Kds of 99 and 93 nM, respectively).XAV939 (0.5 μM, 1.0 μM) reduces DNA-PKcs protein levels 50% of the relative DMSO control in human lymphoblasts. XAV939 induces a second wave of pro-cardiomyocyte gene expression as shown by increased Mesp1 and Isl1expression 2 to 4 days after Wnt inhibition, and by increased Nkx2.5 expression 4 to 6 days after XAV939 addition. XAV-939 (10 nM) has a suppressive effect on elevated MMP-13 levels in both IL-1β-induced SW 1353 cells. XAV-939 (3 mL, 10 nM) has a suppressive effect on elevated MMP-13 levels in the rat OA model.XAV-939(1mg/mL,i.p.) ameliorates the psoriasiform skin disease induced by IMQ. XAV-939 results in a significant decrease in the IMQ-induced epidermal hyperplasia (indicated by acanthosis) and dermal inflammatory infiltrates in mice.
