Application

EB-47 has been used as a poly [ADP-ribose] polymerase 1 (PARP/PARP1/PARPi) inhibitor:
  • to investigate its effect on the activity of matrix metalloproteinase-2 (MMP-2) and compare its inhibitory potencies with the MMP inhibitors
  • in treating human acute monocytic leukemia cells to confirm if PARP1 is responsible for the decrease in high mobility group box protein 1 (HMGB1) supernatant levels
  • to study chromosomal aberrations in response to ionizing radiation (IR) and PARPi in BRCA1-deficient cells that overcome growth arrest (BOGA) cells

Biochem/physiol Actions

1-piperazineacetamide-4-[1-(6-amino-9H-purin-9-yl)-1-deoxy-d-ribofuranuron]-N-(2,3-dihydro-1H-isoindol-4-yl)-1-one (EB-47) can mimic the substrate NAD+ binding. This inhibitor targets the nicotinamide (NI) and adenosine (AD)-subsite within the tankyrase 2 (TNKS2) catalytic domain. EB-47 is one of the most effective TNKS2 inhibitors, with an IC50 of 32 nM, in the presence of piperazine and succinyl linkers that connect the adenosine and isoindolinone cores.
Potent inhibitor of poly (ADP-ribose) polymerase (PARP).

Tankyrases, an enzyme subfamily of human poly(ADP-ribosyl)polymerases, are potential drug targets especially against cancer. We have evaluated inhibition of tankyrases by known PARP inhibitors and report five cocrystal structures of the most potent compounds in complex with human tankyrase 2.

The poly(ADP-ribose) polymerase (PARP) family represents a new class of therapeutic targets with diverse potential disease indications. PARP1 and PARP2 inhibitors have been developed for breast and ovarian tumors manifesting double-stranded DNA-repair defects, whereas tankyrase 1 and 2 (TNKS1 and

Matrix metalloproteinase-2 (MMP-2), a ubiquitously expressed zinc-dependent endopeptidase, and poly(ADP-ribosyl) polymerase (PARP), a nuclear enzyme regulating DNA repair, are activated by nitroxidative stress associated with various pathologies. As MMP-2 plays a detrimental role in heart injuries resulting from enhanced nitroxidative

The success of poly(ADP-ribose) polymerase-1 (PARP-1) inhibitors (PARPi) to treat cancer relates to their ability to trap PARP-1 at the site of a DNA break. Although different forms of PARPi all target the catalytic center of the enzyme, they have

Loss of 53BP1 rescues BRCA1 deficiency and is associated with BRCA1-deficient and triple-negative breast cancers (TNBC) and with resistance to genotoxic drugs. The mechanisms responsible for decreased 53BP1 transcript and protein levels in tumors remain unknown. Here, we demonstrate that
