Description_x000D_ Packaging_x000D_ 5, 25 mg in glass bottle_x000D_ Biochem/physiol Actions_x000D_ ME0328 is a selective inhibitor of ADP-ribosyltransferase-3/poly(ADP-ribose) polymerase-3 (ARTD3/PARP3), a PARP family member involved in DNA repair. ME0328 is the most potent isomer of the four ARTD3 ADP-ribosyltransferase inhibitors. ME0328 selectively inhibits ARTD3 (IC50 of 890 nM) with weaker activity against ARTD1 and ARTD2 (IC50 6.3 and 10.8 μM, respectively), and no significant activity (IC50 >30 μM) against any other ARTD enzyme. ME0328 appears to be the first selective inhibitor of ARTD3/PARP3._x000D_ Features and Benefits_x000D_ This compound is a featured product for Apoptosis research.
