AROMATIC NITROGEN-CONTAINING COMPOUNDS, PREPARATION METHODS AND MEDICINAL USES THEREOFFIELD OF THE INVENTION
[0001] The present invention belongs to the field of medicine, and relates to aromatic nitrogen-containing compound, preparation methods thereof, pharmaceutical compositions comprising the compounds, and medical uses thereof.
[0002] BACKGROUD OF THE INVENTION
[0003] Cells in any living organism possess multiple DNA repair machineries to maintain the genome stability and integrity, which is essential for survival. DNA mismatch repair (MMR) is a highly conserved pathway that plays a critical role in maintaining genomic stability by correcting errors occurred during DNA replication, recombination, and repairing processes. (Pecina-Slaus, N., Kafka, A., Salamon, I. &Bukovac, A. Mismatch Repair Pathway, Genome Stability and Cancer. Front Mol. Biosci. 7, 122 (2020) ) . Deficiency in MMR machinery creates genomic hypermutation and instability, manifested as the high frequency of insertion and deletions at short tracts of repetitive DNA sequences (microsatellites) throughout the genome, a phenomenon known as microsatellite instability (MSI) . (Kim, T.M., Laird, P.W. &Park, P.J. The landscape of microsatellite instability in colorectal and endometrial cancer genomes. Cell 155, 858–868 (2013) , Vernole, P. et al. Common fragile sites in colon cancer cell lines: role of mismatch repair, RAD51 and poly (ADP-ribose) polymerase-1. Mutat. Res 712, 40–48 (2011) ) . . Microsatellites are generated by DNA polymerase slippage during replication or mismatch repair and are susceptible to misalignment and frame shift mutation, which can be recognized and corrected by MMR process in normal cells. However, in cancer cells lacking normal MMR machinery, errors occurred during replication or repair processes are accumulated and the mutation rate in genome is increased (Lower, S.S., McGurk, M.P., Clark, A.G., et al, Satellite DNA evolution: old ideas, new approaches. Curr. Opin. Genet. Dev., 2018; 49: 70-78) . High frequency of deletion and insertion in microsatellites lead to MSI, which contributes to the development of 10-30%of ovarian, colon, gastric and endometrial cancers (Aaltonen, L.A. et al. Clues to the pathogenesis of familial colorectal cancer, Science 260, 812-816 (1993) , Bonneville R et al., Landscape of Microsatellite Instability Across 39 Cancer Types. JCO Precis Oncol. 1: PO. 17.00073 (2017) ) . While MSI-high (MSI-H) cancer patients show a better overall prognosis and reduced metastatic potential with higher tumor mutation burden and immunogenicity comparing to MSS cancers (Kang, S. et al. The significance of microsatellite instability in colorectal cancer after controlling for clinicopathological factors. Med. (Baltim. ) 97, e0019 (2018) ) , MSI-H tumors tend to develop resistance to immunotherapy and chemotherapy (Le, D.T. et al. Phase II Open-Label Study of Pembrolizumab in Treatment-Refractory, Microsatellite Instability-High / Mismatch Repair-Deficient Metastatic Colorectal Cancer: KEYNOTE-164. J. Clin. Oncol. 38, 11–19 (2020) , Overman, M.J. et al. Nivolumab in patients with metastatic DNA mismatch repair-deficient or microsatellite instability-high colorectal cancer (CheckMate 142) : an open-label, multicentre, phase 2 study. Lancet Oncol. 18, 1182–1191 (2017) , Fuca, G. et al. Ascites and resistance to immune checkpoint inhibition in dMMR / MSI-H metastatic colorectal and gastric cancers. J. Immunother. Cancer 10, 4001 (2022) ) .
[0004] Recently, multiple independent large scale functional genomics screen using more than 300 human cancer cell lines identified Werner syndrome RecQ helicase (WRN) as being selectively required for survival of MSI-H cells (Behan, F.M. et al. Prioritization of cancer therapeutic targets using CRISPR-Cas9 screens. Nature 568, 511–516 (2019) , McDonald E.R. et al., Project DRIVE: A Compendium of Cancer Dependencies and Synthetic Lethal Relationships Uncovered by Large-Scale, Deep RNAi Screening. Cell 170 (3) : 577-592 (2017) , Chan, E.M. et al. WRN helicase is a synthetic lethal target in microsatellite unstable cancers. Nature 568, 551–556 (2019) ) . WRN, one of 5 RecQ-like helicases in human, is a multifunctional enzyme with helicase and exonuclease activities and plays important roles in multiple pathways of DNA repair and maintenance of genome integrity including DNA replication, transcription, DNA repair, and telomere maintenance (Bohr, V.A. Rising from the RecQ-age: the role of human RecQ helicases in genome maintenance. Trends Biochem Sci. 33, 609–620 (2008) , Singh, D.K., Ahn, B. &Bohr, V.A. Roles of RECQ helicases in recombination based DNA repair, genomic stability and aging. Biogerontology 10, 235–252 (2009) , Rossi, M.L., Ghosh, A.K. &Bohr, V.A. Roles of Werner syndrome protein in protection of genome integrity. DNA Repair (Amst. ) 9, 331–344 (2010) ) .
[0005] Deletion of WRN leads various defects in cell and genomic structure including cell cycle arrest, DNA breaks, mitotic defects, chromosome shattering, and apoptosis in MSI but not MSS cell lines. (Behan, F.M. et al. Prioritization of cancer therapeutic targets using CRISPR-Cas9 screens. Nature 568, 511–516 (2019) , McDonald E.R. et al., Project DRIVE: A Compendium of Cancer Dependencies and Synthetic Lethal Relationships Uncovered by Large-Scale, Deep RNAi Screening. Cell 170 (3) : 577-592 (2017) , Chan, E.M. et al. WRN helicase is a synthetic lethal target in microsatellite unstable cancers. Nature 568, 551–556 (2019) ) . In addition, loss-of-function mutation and deletion studies on WRN further pinpoint the helicase function of WRN as indispensable for the survival MSI cells (Lieb, S. et al. Werner syndrome helicase is a selective vulnerability of microsatellite instability-high tumor cells. Elife 8, e43333 (2019) ) . These results clearly show that targeting WRN, in particular, the Helicase domain can be a promising strategy for the treatment of for MSI-high cancers.SUMMARY OF THE INVENTION

[0155] Where used as a medicament, the compound of the present disclosure can be administered in the form of a pharmaceutical composition. Said composition can be prepared using methods well known in the art of pharmacy and can be administered through a variety of routes, depending on whether topical or systemic treatment is needed and on the area to be treated. The administration may be topical administration (e.g., transdermal, dermal, ocular and mucosal administration, including intranasal, vaginal and rectal delivery) , pulmonary administration (e.g., inhalation or insufflation of powders or aerosols, including using a nebulizer; intratracheal or intranasal administration) , oral administration or parenteral administration. Parenteral administration comprises intravenous administration, intraarterial administration, subcutaneous administration, intraperitoneal administration or intramuscular injection or infusion; or intracranial administration, e.g., intrathecal or intraventricular administration. Parenteral administration may be performed at a single large dose, or may be performed using, for example, a continuous infusion pump. Pharmaceutical compositions and formulations for topical administration may comprise transdermal patches, ointments, lotions, creams, gels, drops, suppositories, sprays, liquids and powders. Conventional pharmaceutical carriers, water, powdered or oily bases and thickeners and the like may be necessary or desirable.
[0156] In preparing the composition of the present disclosure, the active ingredient is typically mixed with an excipient, diluted with an excipient or enclosed within such a carrier as capsules, sachets, paper or other container forms. Where the excipient serves as a diluent, it may be a solid, semi-solid, or liquid substance used as a vehicle, carrier, or medium for the active ingredient. Thus, the composition may be in the following forms: tablets, pills, powders, lozenges, sachets, cachets, elixirs, suspensions, emulsions, solutions, syrups, aerosols (solid or dissolved in a liquid vehicle) ; ointments, soft and hard gelatin capsules, suppositories, sterile solutions for injection and sterile packaged powders comprising, for example, up to 10%by weight of active compound.
[0157] Some examples of suitable excipients comprise lactose, glucose, sucrose, sorbitol, mannitol, starch, acacia, calcium phosphate, alginate, tragacanth, gelatin, calcium silicate, microcrystalline cellulose, polyvinylpyrrolidone, cellulose, water, syrup, and methylcellulose.

The composition of the present disclosure can be formulated using known methods in the art so as to provide immediate release, sustained release or delayed release of the active ingredient upon being administered to patients.
[0158] The composition may be formulated in unit dosage form. Each dose comprises about 5-1000 mg, more typically about 100-500 mg, of the active ingredient. The term “unit dosage form” refers to physically isolated, single dosage units suitable for human patients and other mammals, each unit comprising a predetermined amount of active substance that can produce the desired therapeutic effects according to calculation and is mixed with a suitable pharmaceutical excipient.
[0159] The effective dose of the active compound may range widely. The active compound is generally administered in a pharmaceutically effective amount. It will be understood, however, that the amount of compound actually administered is generally determined by a physician in light of the relevant circumstances, including the condition to be treated, the chosen route of administration, the actual compound administered; the age, weight and response of the individual patient; the severity of symptoms in the patient, etc.
[0160] In preparing solid compositions such as tablets, the main active ingredient is mixed with pharmaceutical excipients to form a solid preformulation composition of a homogeneous mixture comprising the compound of the present disclosure. Where referring to these preformulation compositions as being homogeneous, it is meant that the active ingredient is generally distributed evenly throughout the composition so the compositions may be readily divided into equally effective unit dosage forms such as tablets, pills and capsules. The solid preformulation is then divided into unit dosage forms of the type described above comprising, for example, about 0.1-1000 mg of the active ingredient of the present disclosure.
[0161] The tablets or pills of the present disclosure may be coated or compounded to give a dosage form affording the advantage of prolonged action. For example, a tablet or pill comprises an inner dosage component and an outer dosage component, the latter being the coated form of the former. The two components can be separated by an enteric coating layer, which serves to resist disintegration in the stomach so that the inner component passes through the duodenum intact or that release is delayed. A variety of substances may be used for such enteric coating layers or coating agents. Such substances comprise various polymeric acids and mixtures of polymeric acids and such substances as shellac, cetyl alcohol and cellulose acetate.
[0162] Liquid forms for oral administration or injection administration in which the compound and composition of the present disclosure may be incorporated comprise aqueous solutions, a suitable flavoring syrup, aqueous or oil suspensions; and emulsions flavored with edible oils such as cottonseed oil, sesame oil, coconut oil or peanut oil: as well as elixirs and similar pharmaceutical vehicles.

Liquid or solid compositions may comprise suitable pharmaceutically acceptable excipients as described above. In certain embodiments, the composition is administered through the oral or nasal respiratory route to achieve topical or systemic effects. The composition may be nebulized using an inert gas. Nebulized solution can be inhaled directly via a nebulizing device, or the nebulizing device can be connected to a mask or an intermittent positive pressure ventilator. Solution, suspension or powder compositions can be administered orally, or nasally via a device that delivers a formulation in a suitable manner.
[0164] The amount of the compound or composition administered to a patient is not fixed and depends on the drug administered, the purpose of the administration such as prevention or treatment; the condition of the patient, the route of administration, etc. In therapeutic applications, the composition may be administered to a patient that is suffering from a disease in an amount sufficient to cure or at least partially suppress the symptoms of the disease and its complications. The effective dosage should depend on the state of the disease to be treated and the judgment of the attending clinician, and the judgment depends on factors such as the severity of the disease, the age, weight and general condition of the patient, etc.
[0165] The composition administered to the patient may be in the form of the pharmaceutical composition described above. These compositions can be sterilized by using conventional sterilization techniques or by filtration. Aqueous solutions can be packaged for use as is, or lyophilized. The lyophilized formulation is mixed with a sterile aqueous carrier prior to administration. The pH of the compound formulation is usually 3-11, more preferably 5-9, and most preferably 7-8. It can be understood that the use of a certain excipient, carrier or stabilizer described above may result in the formation of a pharmaceutical salt.
[0166] The therapeutic dosage of the compound of the present disclosure can be determined, for example, according to: the specific use of the treatment, the route of administration of the compound, the health and condition of the patient, and the judgment of the prescriber. The proportion or concentration of the compound of the present disclosure in the pharmaceutical composition may vary and depends on a variety of factors including the dosage, the chemical properties (e.g., hydrophobicity) , and the route of administration. For example, the compound of the present disclosure can be provided by a physiological buffered aqueous solution comprising about 0.1-10%w / v of the compound parenteral administration. Certain typical dosage ranges are from about 1 μg / kg to about 1 g / kg of body weight / day. In certain embodiments, the dosage range is from about 0.01 mg / kg to about 100 mg / kg of body weight / day. The dosage is likely to depend upon such variables as the type and extent of progression of the disease or condition, the general health of the particular patient, the relative biological potency of the compound selected, the excipient formulation and its route of administration. The effective dosage can be extrapolated from a dose-response curve derived from an in vitro or animal model test system.DETAILED DESCRIPTION OF THE INVENTION

Notwithstanding this variation, the concentration of naturally abundant stable hydrogen isotopes is small and immaterial as compared to the degree of stable isotopic substitution of deuterated derivatives described herein. Thus, unless otherwise stated, when a reference is made to a “deuterated derivative” of a compound of the disclosure, at least one hydrogen is replaced with deuterium at a level that is well above its natural isotopic abundance, which is typically about 0.015%. In some embodiments, the deuterated derivatives disclosed herein have an isotopic enrichment factor for each deuterium atom, of at least 3500 (52.5%deuterium incorporation at each designated deuterium) , at least 4500 (67.5%deuterium incorporation at each designated deuterium) , at least 5000 (75%deuterium incorporation at each designated deuterium) , at least 5500 (82.5%deuterium incorporation at each designated deuterium) , at least 6000 (90%deuterium incorporation at each designated deuterium) , at least 6333.3 (95%deuterium incorporation at each designated deuterium) , at least 6466.7 (97%deuterium incorporation at each designated deuterium) , or at least 6600 (99%deuterium incorporation at each designated deuterium) . The term “isotopic enrichment factor” as used herein means the ratio between the isotopic abundance and the natural abundance of a specified isotope.

[0720] BIOLOGICAL ASSAYS
[0721] WRN Helicase Assay
[0722] To assess the inhibition properties of the invented compounds on WRN helicase activity, a fluorescent assay using forked DNA was set up. In the helicase assay, in-house produced His-WRN527-1072 was used. The fluorescent forked DNA, prepared by annealing of OLIGOA-BHQ2 (TTTTTTTTTTTTTTTTTTTTTTTTTTTTTTCGTACCCGATGTGTTCGTTC-BHQ2) and OLIGOB-TAMRA (TAMRA-GAACGAACACATCGGGTACGTTTTTTTTTTTTTTTTTTTTTTTTTTTTTT) , was used as the substrate. 2.5-fold serial dilution of test compounds were prepared for 7 gradient points with DMSO, and then 1.5 μl of each concentration were added to 48.5 μl of assay buffer (25mM Tris-HCl (pH 8.0) , 50 mM NaCl, 2 mM MgCl2, 1 mM DTT, 0.05%Tween-20, and 2.5 μg / ml BSA) for further dilution. 5 μl of 45 nM WRN protein and 5μl of each diluted compound solution were transferred to 384-well assay plate, and pre-incubated at room temperature for 30 minutes. Each concentration of the compounds was added as triplicate in the plate. Controls were included in the test to validate the assay. Instead of compound solution, assay buffer containing 3%DMSO were added to the positive control (no inhibition) , and no proteins were added to the negative control (maximal inhibition) . Forked DNA and ATP were diluted into 300 nM and 6 mM, respectively, with assay buffer. To initiate the reaction, 5μl of the dsDNA and ATP solution were added to the assay plate. After 60 minutes room temperature incubation, the plate was transferred to Victor Nivo multimode plate reader (Perkin Elmer, Waltham, MA) and the fluorescence outputs were monitored. GraphPad Prism 9 (GraphPad Software, San Diego, CA) was used to carry out the dose-response curves, deriving IC50s.
[0723] WRN ATPase Assay
[0724] To evaluate the inhibition properties of the invented compounds on DNA dependent WRN ATPase activity, an ATPase assay using ADP-Glo assay kit (Promega, Madison, WI) was established. In the ATPase assay, the same WRN protein and DNA substrate as described in helicase assay were used. The serial dilution of the compounds in DMSO was same as helicase assay. In further dilution, 2 μl of each concentration were transferred to 48 μl of assay buffer. 5 μl of 100nM WRN proteins and 2.5 μl of each diluted compound solution were pre-incubated at room temperature for 30 minutes in the 384-well assay plate. All the test wells were set as triplicate. Afterwards, 2.5 μl of assay buffer containing 400 nM DNA substrate and 4 mM ATP were added to each well and incubated for 60 minutes. The protein-free control (maximal inhibition) and no-compound control (no inhibition) were included in the test. To stop the reaction and deplete the excessive ATP, 10 μl of the ADP-GloTM Reagent from the assay kit were added and incubated for 40 minutes. Then, 20 μl of the ATP detection reagent was added. After 30 minutes incubation, the luminescence was measured using Victor Nivo multimode plate reader (Perkin Elmer, Waltham, MA) . Dose-response curves, spanning IC50s, were generated by GraphPad Prism 9 (GraphPad Software, San Diego, CA) .
[0725] Cell Viability Assay
[0726] High microsatellite instability (MSI) cell line SW48 and microsatellite stable MSS cell line SW480 were purchased from ATCC and cultured in DMEM-GlutaMax medium (Gibco, 10564-011) composed of penicillin-streptomycin (Gibco, 15140122) and 10%fetal calf serum (Gibco, 10082-147) at 37℃ in a humidified 5%CO2 incubator.
[0727] Cells were seeded at 3000 cells / well into white-clear-bottom 384 well plates (PerkinElmer) . Next day, twelve 3-fold serial dilutions of 10mM compound stock in DMSO were added into each duplicate well. Blank well contained medium without cells, and DMSO control well contained cells and DMSO only. After 72 hours-treatment, cell viability was analyzed by using 2.0 Assay (Promega, G9243) and luminescent signal was detected on a VICTOR NivoTM multimode plate reader (PerkinElmer) following 10-minute incubation at room temperature. For data analysis, all data points were normalized via subtracting the blank value and calculated a ratio of DMSO control value. The IC50 values were calculated using GraphPad Prism 9.

Mice were injected with 3 million SW48 cells / Matrigel (356234, Corning) mixture subcutaneously into the upper right flank of mice. After the inoculation, tumor bearing mice were monitored regularly and randomly enrolled into treatment groups (n=6 or 7 / group) when tumor reached appropriate volume.
[0731] The test compounds were dissolved in 10%2-hydroxypropyl-beta-cyclodextrin (HPBCD) solution. Mice were treated with vehicle, 10mpk, 20mpk or 40mpk of a test compound by oral gavage (PO) daily (QD) .
[0732] Mice were weighed and tumor volume was measured twice per week. Tumor volume (mm3) was calculated according to 0.5*D*d2, where D=length and d=width of the tumor. Tumor growth inhibition (TGI%) was calculated according to [1- (△ tumor volume treated / △tumor volume control) *100 and tumor regression was calculated according to – (△tumor volume treated / tumor volume treated at day 0) *100 where △ tumor volume represents tumor volume on the measure day minus tumor volume at day 0. Efficacy was calculated according to (△ tumor volume treated / △tumor volume control) *100. Data of tumor growth and body weight change were analyzed using GraphPad Prism 10.
[0733] At the sampling time points after the last dose of the experiment, the blood samples were collected into 1.5ml EDTA-K2 tubes. The sampling time points are 0.25, 0.5, 1, 2, 4, 6, 8 and 24h. The blood samples were centrifuged at 8000rpm for 5 minutes at room temperature. The plasma samples were transferred into pre-labeled tubes and stored at -80℃. For blood PK analysis, an aliquot of 5μl plasma sample was added with 100μl IS (Glipizide, 50 ng / ml) in MeOH. The mixture was vortexed for 1 minute and centrifuged at 5228g for 10 minutes. The supernatant was analyzed by LC-MS / MS-24 (Triple Quad6500) . Data of PK data were analyzed using GraphPad Prism 10.

[0735] For tumor PK analysis, tumor samples were homogenized with 3 volumes (v / w) of PBS. An aliquot of 20μl sample was added with 400μl IS (Glipizide, 50 ng / ml) in MeOH. The mixture was vortexed for 1 minute, and centrifuged at 5228g for 10 min. The supernatant was analyzed by LC-MS / MS-24 (Triple Quad6500) . Data of PK data were analyzed using GraphPad Prism 10.
[0736] For tumor PD analysis, tumor tissue was prepared in 3x volume of RIPA buffer containing phosphatase / protease inhibitors and smashed on ice with homogenizer. Homogenized Sample was mixed several time and place on ice for 30 minutes. After centrifuging at 14, 000g for 20 minutes at 4℃ to pellet down cell debris, supernatants were transferred to a fresh tube for protein quantification using Piece BCA protein Assay Kit (#23225) and western blotting analysis.
[0737] 30μg of tumor protein lysate was loaded and separated by pre-cast gels (4-12%Bis-Tris Midi Gels, Thermofisher, WG1403BOX) , transferred onto polyvinylidene difluoride (PVDF) membrane or pre-wetting Nitrocellulose (NC) membrane, blocked with 5%milk diluted with Tris-buffered saline / Tween (TBST) for 1 h, and then incubated with diluted primary antibody overnight at 4 ℃. The antibodies for detecting protein targets, WRN antibody (8H3, #4665) , phospho-histone H2A. X Ser139 antibody (20E3 #9718) , phospho-Chk2 Thr68 antibody (C13C1 #2197) , p21 Waf1 / Cip1 antibody (12D1 #2947) , were obtained from Cell Signaling Technology. After washing in 0.1%TBST for 5 minutes three times, membrane was incubated with secondary appropriate antibodies diluted in TBST with 5%mild for 1 hour at room temperature on a nutator. After washing membrane, target proteins were detected with Tanon 5200 chemiluminescence image system using the ECL method. Loading control is scanned with Odyssey Infrared Imager. Data of target protein expression level in tumor were analyzed using GraphPad Prism 10.
