Abstract

The synthesis, activity and physical properties of two series of novel potent tetrahydro-1(2H)-isoquinolinone based PARP-1 inhibitors are described. The new structural classes with a non-planar ring system interact specifically with the PARP-1 protein at the nicotinamide-binding site.

  • 13 The catalytic fragment of chicken PARP-1 was obtained from Prof. DeMurcia of the Ecole Supérieure de Biotechnology de Strasbourg. Native PARP-1 was crystallized at pH 8.5 with 18% PEG 4000 and 8% i-PrOH as precipitant, following the protocol of Jung et al.: Jung S. Miranda EA. De Murcia JM. Niedergang C. Delarue M. Schulz GE. DeMurcia GM. J. Mol. Biol.  1994,  244:  114 . Inhibitor complexes were obtained by soaking native crystals with the appropriate inhibitors. The space group and cell dimensions of the crystals obtained were the same as in the published crystal structures. We obtained well diffracting crystals, diffracting to 2.2 and 2.1 Å resolutions, respectively. We did not observe any major differences between our PARP structures and the PARP structures present in the PDB
