[ Name ]:
BYK204165

[Synonym ]:
4-(1-methyl-1H-pyrrol-2-ylmethylene)-4H-isoquinolin-1,3-dione

Biological Activity

[Description]:

BYK204165 is a potent PARP inhibitor. BYK204165 inhibits cell-free recombinant human PARP-1 (hPARP-1) with a pIC50 of 7.35 (pKi=7.05), and murine PARP-2 (mPARP-2) with a pIC50 of 5.38, respectively. BYK204165 displays 100-fold selectivity for PARP-1[1].

[Target]

hPARP-1:7.35 (pIC50)

mPARP-2:5.38 (pIC50)

[In Vitro]

In kinetic experiments with human PARP-1, BYK204165 exhibits potent and competitive inhibition of enzyme activity, yielding a pKi value of 7.05[1]. BYK204165 exhibits low potency of PARP inhibition in C4I cells (pIC50 of 5.75)[1].

[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].
