BYK 204165 is a potent and selective poly(ADP-ribose) polymerase (PARP)-1 inhibitor with pIC50 values of 5.38 and 7.35 for PARP-2 and PARP-1 respectively [1].
PARP1 is a nuclear enzyme activated by strand breaks in DNA and involved in the regulation of various cell processes such as DNA repair, apoptosis, organ dysfunction or necrosis [1].
BYK 204165 (PARP inhibitor XIV) is a cell-permeable isoquinolinedione compound that potently and selectively inhibits PARP1. BYK 204165’s potency is similar or higher than most current standard PARP-1 inhibitors (just slightly lower than PJ34), and it is 100-fold selective for PARP-1 over PARP-2 [1].
BYK 204165 was not tested in vivo because of BYK its poor water solubility.
