Crystal structure of catalytic domain of human poly(ADP-ribose) polymerase complexed with a quinoxaline-type inhibitor
Contents |
Overview
Two classes of quinazolinone derivatives and quinoxaline derivatives were identified as potent and selective poly(ADP-ribose) polymerase-1 and 2 (PARP-1) and (PARP-2) inhibitors, respectively. In PARP enzyme assays using recombinant PARP-1 and PARP-2, quinazolinone derivatives displayed relatively high selectivity for PARP-1 and quinoxaline derivatives showed superior selectivity for PARP-2. SBDD analysis via a combination of X-ray structural study and homology modeling suggested distinct interactions of inhibitors with PARP-1 and PARP-2. These findings provide a new structural framework for the design of selective inhibitors for PARP-1 and PARP-2.
