EB 47, PARP-1 inhibitor

Names

[ CAS No. ]:
1190332-25-2

[ Name ]:
EB 47, PARP-1 inhibitor

[Synonym ]:
2-(4-{[(2R,3R,4S,5S)-5-(6-Amino-9H-purin-9-yl)-3,4-dihydroxytetrahydro-2-furanyl]carbonyl}-1-piperazinyl)-N-(1-oxo-2,3-dihydro-1H-isoindol-4-yl)acetamide dihydrochloride

Biological Activity

[Description]:

EB-47 dihydrochloride, a potent and selective PARP-1/ARTD-1 inhibitor with an IC50 value of 45 nM, shows modest potency against ARTD5 with an IC50 value of 410 nM. EB-47 mimics the substrate NAD+ and extends from the nicotinamide to the adenosine subsite[1].

Signaling Pathways >> Cell Cycle/DNA Damage >> PARP

[In Vitro]

EB-47 dihydrochloride shows inhibition in excess of 50% with CdPARP, and it is able to inhibit CdPARP and HsPARP with IC50 values of 0.86 and 1.0 µM, respectively[1].

[In Vivo]

EB-47 dihydrochloride (2 μM; 5 days) decreases the number of embryo implantation sites and blastocysts at day 5. PARP1 participates in the process of embryo implantation[3].
