4-[(1-Methyl-1H-pyrrol-2-yl)methylene]-1,3(2H,4H)-isoquinolinedione Chemical Properties,Usage,Production

Uses

BYK 204165 is an inhibitor of the poly(ADP-?ribose) polymerase (PARP), and it is 100-fold more selective for PARP-1.

Biochem/physiol Actions

BYK204165 is a potent and selective inhibitor of poly(ADP-ribose) polymerase 1 (PARP1). It is 100-fold selective for PARP-1 over PARP-2.

in vivo

BYK204165 is not investigated in vivo because of its short half-time (t1/2) of 23 min measured at rat microsomes in vitro[1].

IC 50

hPARP-1: 7.35 (pIC50); mPARP-2: 5.38 (pIC50)
