Synthesis of isoquinolinone-based tricycles as novel poly(ADP-ribose) polymerase-1 (PARP-1) inhibitors

The isoquinolinone-based tricyclic compounds were designed and synthesized. Preliminary biological study of these compounds provided potent compounds 17a, 33b, 33c, 33d, and 33g with low nanomolar IC50s against PARP-1 enzyme.
