In kinetic experiments with human PARP-1, BYK204165 exhibits potent and competitive inhibition of enzyme activity, yielding a pK
i
value of 7.05.
BYK204165 exhibits low potency of PARP inhibition in C4I cells (pIC
50
of 5.75).
BYK204165 is not investigated in vivo because of its short half-time (t 1/2 ) of 23 min measured at rat microsomes in vitro.
