BYK 49187 is a potent inhibitor of PARP-1 and PARP-2 with pIC50 value pIC50 values of 8.36 and 7.50 for cell-free recombinant PARP-1 and murine PARP-2 respectively .
Poly (ADP-ribose) polymerase (PARP) is a family of proteins involved in a number of cellular processes involving mainly DNA repair and programmed cell death .
BYK 49187 is a potent inhibitor of human PARP and displays no selectivity for PARP1/2 . PAR formation in A549, C4I, and H9c2 cells was inhibited by BYK49187 with pIC50 values of 7.80, 7.02, and 7.65, respectively. BYK 49187 displays potent inhibitory activity against human PARP-1 in cell-free and cellular assays in vitro .
In the test of effect of BYK 49187 on myocardial infarct size in the rat, intravenous administration of the lower dose of BYK 49187 was nearly ineffective (only 6% reduction in infarct size), whereas the higher dose (3 mg/kg followed by 3 mg/kg/h) caused a significant reduction in infarct size of 22% compared with vehicle. Blood samples of rats treated with 3 mg/kg i.v. BYK49187 significantly inhibited PARP-1 by 80% compared with sham operation .
