Description

DESCRIPTION OF THE FIGURES

[0530] FIG. 1 shows the increase in cellular protein-bound PAR levels following PARG inhibitor treatment.

[0531] FIG. 1A: Kuramochi HGSOC cells were treated for 8 hours either with the compound vehicle DMSO, or with increasing concentrations of Examples 1, 5, 7 or 8, followed by cell extraction and detection of cellular PAR levels by Western blotting. -tubulin was blotted for as a loading control. FIG. 1B: NCI-H1650 NSCLC cells were treated for 8 hours either with the compound vehicle DMSO, or with increasing concentrations of Examples 1, 5, 7 or 8, followed by Western blotting as described above.

EXAMPLES

[0532] All reagents and solvents are generally used as received from the commercial supplier.

[0533] Reactions are routinely performed with anhydrous solvents in well-dried glassware under an argon or nitrogen atmosphere, unless otherwise specified.

[0534] Evaporations are carried out by rotary evaporation under reduced pressure and work-up procedures are carried out after removal of residual solids by filtration.

[0535] All temperatures are given in degree Celsius ( C.) and are approximate temperatures; unless otherwise noted, operations are carried out at room temperature (rt), that is typically in the range 18 C.-25 C.

[0536] Column chromatography (by the flash procedure) is used to purify compounds.

[0537] Classical flash chromatography is often replaced by automated systems. This does not change the separation process per se. A person skilled in the art will be able to replace a classical flash chromatography process by an automated one, and vice versa. Typical automated systems can be used, as they are provided by Buchi, Biotage or Isco (combiflash) for instance.

[0538] A reaction mixture can often be separated by preparative HPLC using e.g. water and acetonitrile as system of eluents, unless otherwise stated. A person skilled in the art will find suitable conditions for each separation; the compounds are isolated after purification as a parent compound or in a form of the corresponding trifluoroacetic acid (TFA) salt or the respective formic acid salt.

[0539] Reactions, which required higher temperature, are usually performed using classical heating instruments; but can also be performed using microwave apparatus (CEM Explorer) at a power of 250 W, unless otherwise noted.

[0540] Hydrogenation or hydrogenolysis reactions can be performed using hydrogen gas in balloon or using Parr-apparatus system or other suitable hydrogenation equipment.

[0541] Concentration of solutions and drying of solids are performed under reduced pressure unless otherwise stated.

[0542] In general, the course of reactions is followed by TLC, HPLC, or LC/MS and reaction times are given for illustration only; yields are given for illustration only and are not necessarily the maximum attainable.

[0543] The structure and purity of the final products of the invention are generally confirmed by NMR spectroscopy, HPLC and mass spectral techniques.

[0544] Proton NMR spectra are recorded on a Brucker 400 MHz spectrometer. Chemical shifts () are reported in ppm relative to Me.sub.4Si or the solvent peak as internal standard, and NMR coupling constants (J values) are in Hertz (Hz). Each peak is denoted as a broad singlet (br), singlet (s), doublet (d), triplet (t), quadruplet (q), doublet of doublets (dd), triplet of doublets (td) or multiplet (m).

[0545] HPLC of the final products are generated using (Method A) a Dionex Ultimate 3000 instrument coupled with Dionex MSQ ESI mode and the following conditions:

[0546] The gradient described could be altered in function of the physico-chemical properties of the compound analysed and is in no way restrictive.

[0547] Mass spectra are generated using a q-Tof Ultima (Waters AG or Thermo Scientific MSQ Plus) mass spectrometer in the positive or negative ESI mode. The system is equipped with the standard Lockspray interface.

[0548] Each intermediate is purified to the standard required for the subsequent stage and is characterized in sufficient detail to confirm that the assigned structure is correct.

[0549] Analytical and preparative HPLC on non-chiral phases are performed using RP-C18 based columns.

PARG Enzymatic Assay

[0743] Inhibition of PARG enzymatic activity by compounds was determined as follows: Recombinant His-tagged human PARG protein expressed in Sf21 insect cells (Adipogen AG, #40T-0022) was aliquoted and stored at 80 C. until use. The artificial enzyme substrate 4-(trifluoromethyl)umbelliferone (TFMU)-ADPr was prepared essentially as described (Drown B S et al, Cell Chemical Biology 2018) and stored at 20 C. as 10 mM stock solutions in DMSO (dimethyl sulfoxide) until use. For reactions, typical final concentration of the enzyme was 1 nM and of the TFMU-ADPr 200 M. Reactions were carried out in black 384-well low volume round bottom assay plates (Corning, #4514) in a final volume of 10 L. To this end, PARG was diluted to 1.67 nM in reaction buffer (50 mM K.sub.2HPO.sub.4, 50 mM KCl, 10 mM -mercaptoethanol, pH 7.4) and 6 L were dispensed per assay well using a multichannel pipette. Then compound was dispensed into each well using an Echo dispenser (BeckmanCoulter) to yield the pre-specified final concentration of the range of concentrations to be tested (typically 8-point serial concentrations ranging from either from 0.01 to 10 M, or from 0.001 to 1 M, or from 0.0001 to 0.1 M), and being volume-corrected with 100% DMSO (0.5% final DMSO concentration in reaction mixtures). Plates were mixed, and after 15 minutes 4 L TFMU-ADPr was added into each well using a multichannel pipette followed by brief mixing. Fluorescence intensity signals were then measured after 30 minutes on an EnVision microplate reader (PerkinElmer) using 380/10 nm and 535/25 nm filters for the excitation and emission, respectively (gain: 150). The assay window was set using DMSO control (top) and a control containing no PARG enzyme (bottom). Delta values were plotted as concentration-response curves fitted to a sigmoidal 4-parameter logistic model to calculate IC.sub.50 values (Scigilian Analyze).

PARG NanoBRET-Based Cellular Target Engagement Assay

[0744] PARG Nano-luciferase construct: The PARG-NanoLuc fusion vector was generated by Promega, by inserting the full length human PARG cDNA sequence encoding the 976 amino acid protein (Gene ID: 8505, UniProt: Q86W56) into the pNLF1-C [CMV/Hygro] vector (C-terminal fusions with NanoLuc enzyme).

[0745] PARG target engagement tracer synthesis: The NanoBRET tracer for PARG was prepared following a previously reported general tracer synthesis procedure.

[0746] PARG Probe Displacement Assay Using NanoBRET: HEK293T (DSMZ #ACC 635) cells transiently transfected with the PARG-NanoLuc fusion construct were resuspended in phenol red-free OptiMEM (Gibco #11058-021) to a concentration of 2.410.sup.5 cells/mL. 9 L per well were then added to a white 384-well low volume microplate (Greiner #784080) and incubated for 24 hours under standard growth conditions.

[0747] Then compound was dispensed into each well using an Echo dispenser (BeckmanCoulter) to yield the pre-specified final concentration of the range of concentrations to be tested (typically 8-point serial concentrations ranging from either from 0.01 to 10 M, or from 0.001 to 1 M, or from 0.0001 to 0.1 M), and being volume-corrected with 100% DMSO (0.5% final DMSO concentration in reaction mixtures).

[0748] After mixing and an incubation at room temperature for 15 min 1 l of the NanoBRET probe (at 0.89 M final concentration) was added to the microplate using a multichannel pipette. The plate was mixed and incubated in a 5% CO.sub.2 environment at 37 C. for 2 hours, and then 5 L per well of a solution consisting of a 1:31.25 dilution of Nano-Glo substrate (Promega) and a 1:500 dilution of NanoLuc extracellular inhibitor (Promega) in phenol red-free OptiMEM was added to each well followed by another mixing step. Filtered luminescence was measured on an EnVision plate reader (PerkinElmer) equipped with a 460 nm filter (donor) and a 645 nm filter (acceptor). BRET ratios were plotted as concentration-response curves fitted to a sigmoidal 4-parameter logistic model to calculate IC.sub.50 values (Scigilian Analyze). Results are shown in Table 2 below.

Detection of Cellular PAR Levels by Western Blotting

[0749] Kuramochi high grade serous ovarian cancer (HGSOC) (JCRB, #JCRB0098) or NCI-H.sub.1650 non-small cell lung cancer (NSCLC) (ATCC, #CRL-5883) cells were cultured in RPMI (BioConcept, #1-41F03-I) containing 10% FCS (Sigma #F9665) and 1% Penicillin-Streptomycin (BioConcept, #4-01F00-H). When cells reached a density of 70% in 6-well plates (TPP, #92006), they were treated either with the test compound vehicle DMSO, or with test compounds at indicated final concentrations for either 4, 6 or 8 hours. Thereafter, the culture medium was removed and cells were collected by scraping in Lysis Buffer (20 mM Tris HCl pH 7.5, 150 mM NaCl, 1 mM EGTA, 1 mM EDTA, 1% Triton and 1% NP-40) containing protease and phosphatase inhibitors (Halt Protease&Phosphatase inhibitor cocktail 100 ThermoScientific, #1861281) and 1 mM PMSF (Fluka, #93482). Cleared lysates were stored in Eppendorf Tubes at 80 C. until use, and protein concentration in lysates was determined using Pierce 660 nm Protein Assay Reagent (ThermoScientific, #22660). 20 g proteins were diluted in 4 Laemmli buffer (Biorad, #161-0747) containing 10% -mercaptoethanol, separated by SDS-PAGE using 10% gels, and then transferred to PVDF membranes (Trans Blot Turbo Transfer Pack BioRad, #1704156) by Trans-Blot Turbo System semidry blotting methodology (BioRad). Primary antibodies were incubated in TBS-0.1% Tween-20 buffer containing 3% bovine serum albumin (Millipore, #81-053-3) overnight at 4 C. The following primary antibodies were used: anti-PAR (Ab-1) mouse monoclonal antibody (10H) (Millipore, #AM80-100UG), Poly/Mono-ADP ribose (PAR/MAR) (E6F6A) rabbit monoclonal antibody (Cell Signaling, #83732), and rabbit anti-GAPDH clone 14C10 (Cell Signaling, #2118S) diluted 1:2000 or mouse -tubulin (Sigma, #T5168) diluted 1:5000 to control for equal protein loading. Horseradish peroxidase (HRP)-conjugated secondary antibodies were incubated one hour at room temperature diluted 1:5000 in TBS-0.1% Tween-20 buffer containing 5% nonfat-dried bovine milk (Sigma, #M7409). The following secondary antibodies were used: Goat anti-mouse-HRP (Jackson, #115-035-146) and goat anti-rabbit-HRP (Jackson, #111-035-144). Membranes were incubated with enhanced chemiluminescence (ECL) Prime Western Blot Detection Reagent (Amersham, #RPN2236) to detect specific signals using the Fusion SOLO S imaging system (Vilber Lourmat). Results are shown in FIG. 1.

Cell Proliferation Assays

[0750] For Examples 1-11, RMUG-S mucinous cystadenocarcinoma (JCRB, #IF050320) and TOV-112D endometrioid adenocarcinoma (ATCC, #CRL-11731) ovarian cancer cell lines were grown in DMEM/F-12 with glutamine (BioConcept, #1-26F09-I) and RPMI with glutamine (BioConcept, #1-41F03-1), respectively, and both media containing 10% FBS (Sigma-Aldrich, #F9665) and supplemented with 1% Penicillin-Streptomycin (BioConcept, #4-01F00-H) using standard cell culture techniques. RMUG-S and TOV-112D ovarian cancer cell lines were selected as highly PARG dependent and having low PARG dependency, respectively, based on their publically available PARG shRNA (short hairpin ribonucleic acid) dropout profiles in the Cancer Dependency Map (DepMap) data portal (Broad Institute DepMap Project; Cheung H W et al, Proceedings of the National Academy of Sciences 2011; Cowley G S et al, Scientific Data 2014; McDonald E R et al, Cell 2017). PARG dependency of these cell lines was independently verified and confirmed by genetic and pharmacological means using shRNA-mediated PARG depletion, and the previously reported cell-permeable quinazolinedione PARG inhibitor tool compound PDD00017273 (Pillay N et al, Cancer Cell 2019). Thus, growth inhibition of the RMUG-S cell line serves as a functional on-target inhibition readout, while observing potent growth inhibition of TOV-112D is indicative of compound off-target activity. Cells were seeded in 96-well plates with clear bottom (Huberlab, #7.655 090) at a seeding density of 5000 cells per well in 100 L of medium, and the plates were incubated overnight at 37 C. with 5% CO.sub.2 prior to treatment with compounds. Experimental compounds were prepared in DMSO at a concentration of 10 mM. Compounds were distributed at the desired final concentrations using the Tecan D300e Digital Dispenser (TECAN) and normalized to the highest DMSO volume. The plates were incubated for 120 hours and cell numbers were then measured using CellTiter-Glo (Promega, #G9241), essentially as recommended by the manufacturer. Briefly, for the CellTiter-Glo proliferation readout, 50 L of the reconstituted CellTiter-Glo 2.0 Reagent were added to 100 L of medium containing cells. The plates were incubated at room temperature for 10 minutes to stabilize the luminescent signal, and luminescence intensity signals were then measured with a Synergy 4 microplate reader (BioTek Instruments). Relative proliferation values were calculated by normalizing the raw data using DMSO-treated cells (100% proliferation) and the signals obtained from cells that were evaluated at the time of compound addition (0% proliferation). The concentration-response data were fitted to a sigmoidal 4-parameter logistic model with the maximum constrained to 100%. GI.sub.50 values were calculated from the curves as the compound concentrations reducing proliferation to 50%. Results are shown in Table 2 below.

[0751] The cell proliferation assay protocol was modified and used for RMUG-S for Examples 12-44, and subsequently used to test Examples 1-44 in the NCI-H1650 cell line.

Modified Cell Proliferation Assays

[0752] NCI-H1650 (ATCC, #CRL-5883) or RMUG-S were seeded on day 1 at 300 cells per well in a 384-well plate (Greiner, #781080) that assure assay linearity and optimal signal intensity in 25 L of RPMI1640 media (Pan Biotech, #P04-22100) containing 10% FCS (Capricorn, #FBS-11A; Lot. CP22-5141) and 1% Glutamine (Pan Biotech, #P04-80100). After incubation for 24 h in humidified chambers at 37 C./5% CO.sub.2, compounds/DMSO were dispensed at different concentrations using an Echo 520 (Beckman Coulter). Cells were further incubated for 120 h at 37 C. and 5% CO.sub.2. Cells treated with the compound vehicle DMSO were used as negative controls and cells treated with 10 M Staurosporine (LC Laboratories, #S-9300) served as positive controls.

[0753] At day 6 the CellTiter Glo Reagent was prepared according to the instructions of the kit (Promega Inc.): Reagent was mixed 1:1 with cell culture medium. Thereon, mixture and assay plates were equilibrated at room temperature for 20 min. Equal volumes of the reagent-medium-mixture were added to the volume of culture medium present in each well. The plates were mixed at 200 rpm for 2 minutes on an orbital shaker (Timix5, Edmund Buehler GmbH). The microplates were then incubated at room temperature for 10 minutes for stabilization of the luminescent signal. Following incubation, the luminescence was recorded on a Victor X5 microplate reader (Perkin Elmer) using a 200 ms integration time. The data was then analyzed with Excel using the XLFIT Plugin (dose response Fit 205) for determination of the concentration necessary for half-maximal inhibition (i.e. the inflection point of the fitted curve).

[0754] As quality control the Z-factor was calculated from 16 positive and negative control values. Only assay results showing a Z-factor0.5 were used for further analysis.
