The lack of inhibitors that are selective for individual poly-ADP-ribose polymerase (PARP) family members has limited our understanding of their roles in cells. Here, we describe a chemical genetics approach for generating selective inhibitors of an engineered variant of PARP10. We synthesized a series of C-7 substituted 3,4-dihydroisoquinolin-1(2H)-one (dq) analogues designed to selectively inhibit a mutant of PARP10 (LG-PARP10) that contains a unique pocket in its active site. A dq analogue containing a bromo at the C-7 position demonstrated a 10-fold selectivity for LG-PARP10 compared to its WT counterpart. This study provides a platform for the development of selective inhibitors of individual PARP family members that will be useful for decoding their cellular functions.
