[0065] As used herein, "treatment" or "treating", or "palliating" or "ameliorating" are used interchangeably. These terms refer to an approach for obtaining a beneficial or desired result, including but not limited to a therapeutic and / or prophylactic effect. "Therapeutic effect" means the eradication or amelioration of a primary disease being treated. Also, a therapeutic effect is achieved by the eradication or amelioration of one or more physiological symptoms associated with the primary disease such that improvement is observed in the patient, even though the patient still suffers from the primary disease. For a prophylactic effect, the composition is administered, in some embodiments, to a patient at risk of developing a particular disease, or a patient in whom one or more physiological symptoms of the disease have been reported, even if the disease has not been diagnosed. Poly(ADP-ribose) glycohydrolase
[0066] Single-strand DNA breaks (SSBs) are the most frequently occurring type of lesion in cells, and poly(ADP-ribose) glycohydrolase (PARG), together with poly(ADP-ribose) polymerase (PARP), is involved with numerous other proteins in another repair mechanism called single-strand break repair and base excision repair. PARG and PARP are involved in DNA replication and repair, and cells in which PARG is depleted or inhibited show high sensitivity to DNA-damaging agents. PARG can reverse the action of the PARP enzyme by hydrolyzing the ribose linkage present in poly(ADP-ribose) (PAR). PARG is a primary hydrolase involved in the degradation of PAR, using both endoglycohydrolase and exoglycohydrolase activities, and is one of the hydrolases responsible for the rapid removal of the ADP-ribose moiety from modified proteins to recycle NAD + back to the cell system.
[0065]
[0067] PARG inhibition may confer a therapeutic advantage in PARP inhibitor-resistant cells. Furthermore, PARG depletion has been reported to lead to a gene expression pattern that is significantly different from that of PARP depletion in breast cancer cells. Current models indicate that PARG depletion leads to PARP-dependent effects in DNA repair, but recent studies have shown a mechanistic divergence from PARP inhibition. After genotoxic stimulation, PARG depletion leads to a decrease in NAD levels, in contrast to PARP depletion, which results in lung cancer cell death that can lead to energy deficiency.
[0066]
[0068] PARG exists as a single gene with isoforms in the nucleus, mitochondria, and cytosol. The only other known protein with glycohydrolase activity that is localized to the mitochondria is ARH3. Although mainly known for its direct role in DNA repair, PARG strongly affects PAR signaling in the splicing, transcription, and epigenetic pathways. PARG can also play a role in preventing the accumulation of cytoplasmic PAR and parthanatos, a PAR-mediated type of cell death. The accumulation of perturbed replication intermediates can lead to synthetic lethality in certain situations. PARG inhibitors can be used as a cancer treatment, either as a single agent or in combination with therapeutic agents or radiotherapy.
[0067]
[0069] When other mechanisms of DNA repair are non-functional, cancer cells may proliferate by utilizing specific DNA repair pathways. Tumors carrying mutations in proteins involved in double-strand break repair are often highly sensitive to PARP inhibitors for SSB repair. There is already some evidence that PARG depletion inhibits SSB repair and reduces the survival rate of BRCA2-deficient cells. However, other tumor mutations can result in deficiencies in the double-strand DNA repair machinery (so-called "BRCA-ness"), thereby making tumor cells sensitive to PARG inhibition.
[0068]
[0070] PARG depletion has been studied in many mouse and human model systems. Mouse cells lacking or depleted of PARG show high sensitivity to experimental and clinical DNA-damaging agents. However, this suggests specificity for PARG function in certain pathways of DNA damage repair and chemotherapy and radiotherapy, as a lack of PARG does not make cells sensitive to all agents (e.g., gemcitabine, camptothecin). In humans, PARG depletion makes cells from lung, cervical, and pancreatic cancers sensitive to γ-irradiation or experimental DNA-damaging agents (e.g., hydrogen peroxide, methyl methanesulfonate).
[0069]
[0071] In humans, the PARG gene is located on a single chromosome at locus 10q11.23 - 21, but may undergo alternative splicing, and PARG 111 , PARG 102 , PARG 99 , PARG 60 , PARG 55 and so on, resulting in various PARG isoforms. The various PARG isoforms can be localized to various intracellular locations. For example, the largest isoform, PARG - 111 is localized in the nucleus and can be translocated to the cytoplasm. PARG 111 has four domains, namely, the PARG catalytic domain, the macrodomain, the region controlling natural denaturation, and the hinge domain. PARG 102 and PARG 99 lacking a part of the N - terminal domain can be localized in the cytoplasm and have a perinuclear distribution that can translocate to the nucleus. PARG 102 and PARG 99 have a higher degree of overall cell activity. PARG 60 and PARG 55 can be localized within mitochondria and lack catalytic activity.
[0070]
[0072] PARG can function together with PARP for DNA repair. The PARP family of enzymes has at least 17 members, among which PARP1 - 3 are localized in the nucleus and are involved in many cellular processes. Nuclear PARP enzymes are part of DNA repair and are also involved in transcription, chromatin modification, and cell death pathways. PARP1 - 3 contain DNA - binding domains to facilitate interaction with DNA and are activated by DNA damage. One way in which PARP1 - 3 function is by adding large - scale post - translational modifications to other proteins and themselves, and PARG can reverse this. By inhibiting PARG, the reaction rate of depolymerization can be changed, and as a result, proteins are inappropriately modified.
[0071] PARG enzyme function
[0073] PARG and PARP can work together to promote downstream cellular processes. The exoglycohydrolase activity of PARG involves binding to the two most distal ADP-ribose residues within the PARG chain, resulting in free PAR and mono-ADP-ribose moieties. Mono-ADP-ribose is metabolized to AMP and ribose 5'-phosphate by ADP-ribose pyrophosphohydrolase. Subsequently, AMP is utilized in cell signaling pathways while ribose can be utilized for other biomolecules such as, but not limited to, DNA and RNA. PARG endoglycohydrolase activity can occur via excessive PARP activity which would result in the generation of free PAR chains. Free PAR chains may be associated with apoptosis and function to signal cell death.
[0072]
[0074] PARG also functions to maintain a stable level of PAR to protect cells against parthanatos, which is triggered by the release of apoptosis-inducing factor (AIF) from mitochondria to the nucleus. Within the nuclear chromatin environment, AIF can cause large-scale DNA fragmentation and chromatin condensation, potentially leading to cell death. Depletion of PARG can prevent the release of AIF from mitochondria to protect against oxidative stress-induced parthanatos. PARG can also have a useful function in telomere maintenance by negatively regulating access to telomeric DNA by reversing the ADP-ribosylation of the telomere-specific protein TRF1. This leads to PARG contributing to the repair and replication control of telomeres.
[0073]
[0075] PARP enzymes can fulfill many functions of DNA repair, such as, but not limited to, single-strand DNA breaks. Therefore, PARP inhibitors have been studied for cancers with defects in the DNA damage response mechanism (Pilger et al., Genes Dev. 2021). The immune response of PARP is related to DNA repair, and DNA lesions can activate antitumor immunity. (Pilger et al., Genes Dev. 2021). Studies have shown that PARP inhibitors can affect the innate and adaptive immune responses of cells through DNA damage and repair mechanisms, highlighting the relationship between PARP inhibitors for use in DNA damage responses, their therapeutic use with immune checkpoint inhibitors, or their use as biomarkers.
[0074]
[0076] PARP enzymes can catalyze the addition of PAR subunits to receptor proteins and themselves. PARP inhibitors have been studied for cancer treatment and have been successful in treatment of ovarian, breast, and prostate cancers. PARP inhibitors have been found to treat defects in the homologous recombination DNA repair pathway, particularly BRCA1 and BRCA2 mutant tumors (Ding et al., Cell Reports 2018; Reislander et al., Nature Comm. 2019). Thus, BRCA mutant cells are dependent on PARP-mediated DNA repair and survival and may therefore be sensitive to PARP inhibition.
[0075]
[0077] PARP inhibitors have also shown clinical efficacy in subjects with BRCA mutations. PARP inhibitors that can elicit local and systemic anti-tumor immunity can participate in the innate immune response through the stimulator of interferon genes (STING)-dependent pathway (Ding et al., Cell Reports 2018; Reislander et al., Nature Comm. 2019). Studies have found that STING-dependent type I interferon (IFN) signaling may mediate the therapeutic effect of PARP inhibition in BRCA1-deficient tumors. Furthermore, treatment with PARP inhibitors can stimulate the upregulation of IFN signaling genes in vitro and in vivo, and it has been found that it can promote the upregulation of the innate immune response in BRCA1-deficient tumors or BRCA2-deficient tumors (Reislander et al., Nature Comm. 2019).
[0076]
[0078] PARP inhibitors exhibit synthetic lethality associated with loss of BRCA function and can be used for therapeutic treatment of ovarian cancer for monotherapy treatment in patients with germline or somatic BRCA1 mutations and BRCA2 mutations, or can be used as maintenance therapy after platinum chemotherapy in subjects with platinum-sensitive recurrent disease (Ding et al., Cell Reports 2018). Further studies suggest that adding a PD-1 blocker can extend the activity of PARP inhibitors by overcoming the increase in the expression of PD-L1 in tumor cells that occurs when cells are treated with PARP inhibitors alone (Ding et al., Cell Reports 2018). Prior art PARG inhibitors
[0079] PARG inhibitors have not been studied to the extent of PARP inhibitors. Clinical resistance to PARP inhibitors has already been explained, and therefore, it is necessary to discover alternative inhibitors that target the DNA damage repair pathway. The aforementioned PARG inhibitors include bicyclic aryl compounds and heteroaryl compounds described in WO2016 / 092326, WO2016 / 097749, WO2021 / 055744, WO2018 / 237296, WO2020 / 023802, and WO2020 / 205646. There remains a need to find alternative PARG inhibitors that have strong independent efficacy regarding the DNA cleavage repair cycle and a synergistic effect with PARP inhibitors.

[0152] General synthetic scheme
[0114] The PARG inhibitory compounds disclosed herein can be prepared by a variety of synthetic routes including, but not limited to, the routes described in Scheme I or II below.
[0153]
Chemical formula
[0154]
[0115] When 2,4 - quinazolinone derivative 1.1 is reacted with chlorosulfonic acid, chlorosulfonyl derivative 1.2 is obtained. Reacting compound 1.2 with a substituted amine gives sulfonamide 1.3. Chlorinating compound 1.3 gives dichloroquinazoline derivative 1.4, which undergoes selective hydrolysis at the 4 - position when treated with an aqueous base. 2 - chloroquinazoline 1.5 is substituted at the amide nitrogen by treatment with a suitable electrophile under basic conditions to give compound 1.6. The cyclization of the 5 - membered imidazole ring is initiated by substitution of the chloro group by reaction with a suitable amino alcohol to give 2 - aminoquinazoline derivative 1.7. The ring - closure of the imidazole ring to obtain the target compound 1.8 is achieved under Mitsunobu conditions (e.g., DEAD, PPh3), or alternatively, by activation of the alcohol as a suitable leaving group such as conversion to a methanesulfonate or chlorination with SOCl2, followed by ring - closure by treatment with a base. One of ordinary skill in the art will recognize that using a 1,2 - amino alcohol gives a 5 - membered imidazole compound 1.8, while using a 1,3 - amino alcohol gives a similar 6 - membered compound. Similarly, using a 1,4 - amino alcohol gives a similar 7 - membered compound. In this case, a single stereoisomer of the target compound is desired, and chiral chromatography using supercritical fluid chromatography can be used. Alternatively, if necessary, a non - racemic chiral starting material such as an amino alcohol may be used.
[0155]
Chem.
[0156]
[0116] Anthranilic acid derivative 2.1 is condensed with alkyl isothiocyanate to obtain 2-thioxo-2,3-dihydroquinazolin-4(1H)-one derivative 2.2. Chlorination gives compound 2.3, which undergoes substitution with amino alcohol to obtain quinazolinone derivative 2.4. The ring closure of the imidazole ring to obtain compound 2.5 is achieved under Mitsunobu conditions (e.g., DIAD, PPh3), or alternatively, by activation of the alcohol as a suitable leaving group with a reagent such as methanesulfonyl chloride (MeSO2Cl) or thionyl chloride (SOCl2), followed by ring closure with treatment with a base. One skilled in the art will recognize that using a 1,2-amino alcohol gives a 5-membered imidazole compound 2.5, while using a 1,3-amino alcohol gives a similar 6-membered compound. Similarly, using a 1,4-amino alcohol gives a similar 7-membered compound. Palladium-catalyzed thiolation of imidazole compound 2.5 gives sulfide 2.6, which undergoes oxidative chlorination to obtain sulfonyl chloride 2.7. Reacting the sulfonyl chloride with a suitable amine gives the target compound 2.8.
[0157]
[0117] One skilled in the synthesis of organic compounds will recognize that depending on the nature of the substituents in groups R 1 ~R 5 and R 7 , modifications of Scheme I or II may be required. Such changes may include, for example, the use of protecting groups to change the reactivity of the substituents or to change the time and temperature for the reaction. Further modifications of the compounds of formula 1.8 or 2.8 can be carried out to reach the desired PARG inhibitory compound. In this event, a single stereoisomer of the target compound is desired, and chiral chromatography using supercritical fluid chromatography can be used. Alternatively, a non-racemic chiral starting material such as an amino alcohol may be used if necessary.
[0158]
[0118] When using appropriate starting materials, the PARG inhibitory compounds according to formula (I) or (Ia), or described herein in Tables 1 or 2A - 2I, can be synthesized using the methods described in Schemes I or II.

[0331] II. Biological evaluation
[0250] Example 1: Nuclear PAR accumulation assay
[0251] The IC of the compound for the inhibition of cellular PARG was determined using an immunofluorescence high-content imaging assay for nuclear PAR accumulation 50Values were determined. The day before compound treatment, HeLa cells were seeded in 96-well plates at 15,000 cells / well, then treated with various concentrations of the test compound and incubated at 37 °C + 5% CO2 for 1 hour. Following the test compound treatment, methyl methanesulfonate (MMS) was added at a final concentration of 50 μg / mL and the cells were incubated for an additional 1 hour. After treatment, the cells were fixed with ice-cold 95% methanol, the plates were sealed and placed at -20 °C for 15 minutes. The cells were then washed once with phosphate-buffered saline (PBS) and permeabilized with 0.1% Triton-X100 for 20 minutes at room temperature. The cells were washed again once with PBS and incubated overnight at 4 °C with an anti-poly ADP ribose (PAR) monoclonal antibody (Millipore Part# AM80 clone 10H) diluted 1:1,000 in 5% fetal bovine serum + 0.1% Tween-20 + PBS. The cells were then washed three times with PBS before incubation for 1 hour at room temperature with a fluorescently conjugated goat anti-mouse antibody (Invitrogen A32723) diluted 1:500 in 5% FBS + 0.1% Tween-20 + PBS. The cells were washed three times again with PBS and the nuclei were labeled by incubating with 1 μg / mL of DAPI (4’,6-diamidino-2-phenylindole). High-content fluorescence microscopy was used to evaluate PAR accumulation in the nuclei. Four fields per well were acquired at 20x magnification, resulting in at least 1,000 cells being analyzed per well. High-content software (CellReporterXpress) was used to detect the nuclei, segment using the DAPI channel, and quantify the fluorescence intensity in the PAR-Alexa488 channel within the nuclear region. Both the mean intensity of each nucleus and the percentage of PAR-positive cells were quantified. The percentage of PAR-positive cells was identified by having an anti-PAR label greater than the threshold set by the DMSO-treated control cells of the vehicle. The data were normalized by the control values of 0.1% DMSO and the reference compound, representing 0% to 100% inhibition of enzyme activity, respectively, to calculate the percentage of inhibition of PARG by the test compound. A four-parameter logistic curve fitting software was used to generate the concentration-response curve and IC 50 values.
