OUL35 is an inhibitor of poly(ADP-ribose) polymerase 10 (PARP10; IC50 = 329 nM).1 It is selective for PARP10 over a panel of 15 PARP enzymes, including PARP4, PARP14, and PARP16 (IC50s = 22.6, 23.4, and 4.17 μM, respectively). OUL35 (10 μM) reverses inhibition of HeLa cell proliferation induced by PARP10 overexpression. It sensitizes HeLa cells to hydroxyurea , increasing hydroxyurea-induced inhibition of cell proliferation when used at a concentration of 5 μM.

Potent 2,3-dihydrophthalazine-1,4-dione derivatives as dual inhibitors for mono-ADP-ribosyltransferases PARP10 and PARP15
Eur J Med Chem 2022 Jul 5;237:114362.PMID:35500474DOI:10.1016/j.ejmech.2022.114362.
While human poly-ADP-ribose chain generating poly-ARTs, PARP1 and 2 and TNKS1 and 2, have been widely characterized, less is known on the pathophysiological roles of the mono-ADP-ribosylating mono-ARTs, partly due to the lack of selective inhibitors. In this context, we have focused on the development of inhibitors for the mono-ART PARP10, whose overexpression is known to induce cell death. Starting from OUL35 (1) and its 4-(benzyloxy)benzamidic derivative (2) we herein report the design and synthesis of new analogues from which the cyclobutyl derivative 3c rescued cells most efficiently from PARP10 induced apoptosis. Most importantly, we also identified 2,3-dihydrophthalazine-1,4-dione as a new suitable nicotinamide mimicking PARP10 inhibitor scaffold. When it was functionalized with cycloalkyl (8a-c), o-fluorophenyl (8h), and thiophene (8l) rings, IC50 values in the 130-160 nM range were obtained, making them the most potent PARP10 inhibitors reported to date. These compounds also inhibited PARP15 with low micromolar IC50s, but none of the other tested poly- and mono-ARTs, thus emerging as dual mono-ART inhibitors. Compounds 8a, 8h and 8l were also able to enter cells and rescue cells from apoptosis. Our work sheds more light on inhibitor development against mono-ARTs and identifies chemical probes to study the cellular roles of PARP10 and PARP15.
Evaluation of 3- and 4-Phenoxybenzamides as Selective Inhibitors of the Mono-ADP-Ribosyltransferase PARP10
ChemistryOpen 2021 Oct;10(10):939-948.PMID:34145784DOI:10.1002/open.202100087.
Intracellular ADP-ribosyltransferases catalyze mono- and poly-ADP-ribosylation and affect a broad range of biological processes. The mono-ADP-ribosyltransferase PARP10 is involved in signaling and DNA repair. Previous studies identified OUL35 as a selective, cell permeable inhibitor of PARP10. We have further explored the chemical space of OUL35 by synthesizing and investigating structurally related analogs. Key synthetic steps were metal-catalyzed cross-couplings and functional group modifications. We identified 4-(4-cyanophenoxy)benzamide and 3-(4-carbamoylphenoxy)benzamide as PARP10 inhibitors with distinct selectivities. Both compounds were cell permeable and interfered with PARP10 toxicity. Moreover, both revealed some inhibition of PARP2 but not PARP1, unlike clinically used PARP inhibitors, which typically inhibit both enzymes. Using crystallography and molecular modeling the binding of the compounds to different ADP-ribosyltransferases was explored regarding selectivity. Together, these studies define additional compounds that interfere with PARP10 function and thus expand our repertoire of inhibitors to further optimize selectivity and potency.
4-(Phenoxy) and 4-(benzyloxy)benzamides as potent and selective inhibitors of mono-ADP-ribosyltransferase PARP10/ARTD10
Eur J Med Chem 2018 Aug 5;156:93-102.PMID:30006177DOI:10.1016/j.ejmech.2018.06.047.
Human Diphtheria toxin-like ADP-ribosyltranferases (ARTD) 10 is an enzyme carrying out mono-ADP-ribosylation of a range of cellular proteins and affecting their activities. It shuttles between cytoplasm and nucleus and influences signaling events in both compartments, such as nuclear factor kappa-light-chain-enhancer of activated B cells (NF-κB) signaling and S phase DNA repair. Furthermore, overexpression of ARTD10 induces cell death. We recently reported on the discovery of a hit compound, OUL35 (compound 1), with 330 nM potency and remarkable selectivity towards ARTD10 over other enzymes in the human protein family. Here we aimed at establishing a structure-activity relationship of the OUL35 scaffold, by evaluating an array of 4-phenoxybenzamide derivatives. By exploring modifications on the linker between the aromatic rings, we identified also a 4-(benzyloxy)benzamide derivative, compound 32, which is potent (IC50 = 230 nM) and selective, and like OUL35 was able to rescue HeLa cells from ARTD10-induced cell death. Evaluation of an enlarged series of derivatives produced detailed knowledge on the structural requirements for ARTD10 inhibition and allowed the discovery of further tool compounds with submicromolar cellular potency that will help in understanding the roles of ARTD10 in biological systems.
Analogs of TIQ-A as inhibitors of human mono-ADP-ribosylating PARPs
Bioorg Med Chem 2021 Dec 15;52:116511.PMID:34801828DOI:10.1016/j.bmc.2021.116511.
The scaffold of TIQ-A, a previously known inhibitor of human poly-ADP-ribosyltransferase PARP1, was utilized to develop inhibitors against human mono-ADP-ribosyltransferases through structure-guided design and activity profiling. By supplementing the TIQ-A scaffold with small structural changes, based on a PARP10 inhibitor OUL35, selectivity changed from poly-ADP-ribosyltransferases towards mono-ADP-ribosyltransferases. Binding modes of analogs were experimentally verified by determining complex crystal structures with mono-ADP-ribosyltransferase PARP15 and with poly-ADP-ribosyltransferase TNKS2. The best analogs of the study achieved 10-20-fold selectivity towards mono-ADP-ribosyltransferases PARP10 and PARP15 while maintaining micromolar potencies. The work demonstrates a route to differentiate compound selectivity between mono- and poly-ribosyltransferases of the human ARTD family.
Small-Molecule Chemical Probe Rescues Cells from Mono-ADP-Ribosyltransferase ARTD10/PARP10-Induced Apoptosis and Sensitizes Cancer Cells to DNA Damage
Cell Chem Biol 2016 Oct 20;23(10):1251-1260.PMID:27667561DOI:10.1016/j.chembiol.2016.08.012.
Members of the human diphtheria toxin-like ADP-ribosyltransferase (ARTD or PARP) family play important roles in regulating biological activities by mediating either a mono-ADP-ribosylation (MARylation) of a substrate or a poly-ADP-ribosylation (PARylation). ARTD10/PARP10 belongs to the MARylating ARTDs (mARTDs) subfamily, and plays important roles in biological processes that range from cellular signaling, DNA repair, and cell proliferation to immune response. Despite their biological and disease relevance, no selective inhibitors for mARTDs are available. Here we describe a small-molecule ARTD10 inhibitor, OUL35, a selective and potent inhibitor for this enzyme. We characterize its selectivity profile, model its binding, and demonstrate activity in HeLa cells where OUL35 rescued cells from ARTD10 induced cell death. Using OUL35 as a cell biology tool we show that ARTD10 inhibition sensitizes the cells to the hydroxyurea-induced genotoxic stress. Our study supports the proposed role of ARTD10 in DNA-damage repair and provides a tool compound for selective inhibition of ARTD10-mediated MARylation.
