Design, Synthesis And Evaluation Of Potential Inhibitors For Poly(Adp-Ribose) Polymerase Members 1 And 14

Poly(ADP-ribose) polymerase (PARP) members PARP1 and PARP14 belong to an 18-member superfamily of post-translational modifying enzymes. A library of 9 novel non-NAD analog amine compounds was designed, synthesized and evaluated for inhibitory activity against PARP1 and PARP14. Both in silico studies and in vitro assays identified compound 2 as a potential PARP1 inhibitor, inhibiting activity by 93 +/- 2% (PARP14 inhibition: 0 +/- 6%), and 7 as a potential PARP14 inhibitor, inhibiting activity by 91 +/- 2% (PARP1 inhibition: 18 +/- 4%), at 10-mu m concentration. Key in silico interactions with TYR907 in PARP1 and TYR1620 and TYR1646 in PARP14 have been identified. Compound 2 and compound 7 have been identified as potential leads for the development of selective PARP inhibitors.
