FIELD OF THE INVENTION

The disclosure provides compounds as well as their compositions and methods of use. The compounds modulate KRAS activity and are useful in the treatment of various diseases including cancer.

BACKGROUND OF THE INVENTION

Ras proteins are part of the family of small GTPases that are activated by growth factors and various extracellular stimuli. The Ras family regulates intracellular signaling pathways responsible for growth, migration, survival and differentiation of cells. Activation of RAS proteins at the cell membrane results in the binding of key effectors and initiation of a cascade of intracellular signaling pathways within the cell, including the RAF and PI3K kinase pathways. Somatic mutations in RAS may result in uncontrolled cell growth and malignant transformation while the activation of RAS proteins is tightly regulated in normal cells (Simanshu, D. et al. Cell 170.1 (2017): 17-33).

The Ras family is comprised of three members: KRAS, NRAS and HRAS. RAS mutant cancers account for about 25% of human cancers. KRAS is the most frequently mutated isoform accounting for 85% of all RAS mutations whereas NRAS and HRAS are found mutated in 12% and 3% of all Ras mutant cancers respectively (Simanshu, D. et al. Cell 170.1 (2017): 17-33). KRAS mutations are prevalent amongst the top three most deadly cancer types: pancreatic (97%), colorectal (44%), and lung (30%) (Cox, A.D. et al. Nat Rev Drug Discov (2014) 13:828-51). The majority of RAS mutations occur at amino acid residue 12, 13, and 61. The frequency of specific mutations varies between RAS gene isoforms and while G12 and Q61 mutations are predominant in KRAS and NRAS respectively, G12, G13 and Q61 mutations are most frequent in HRAS. Furthermore, the spectrum of mutations in a RAS isoform differs between cancer types. For example, KRAS G12D mutations predominate in pancreatic cancers (51%), followed by colorectal adenocarcinomas (45%) and lung cancers (17%) while KRAS G12 V mutations are associated with pancreatic cancers (30%), followed by colorectal adenocarcinomas (27%) and lung adenocarcinomas (23%) (Cox, A.D. et al. Nat Rev Drug Discov (2014) 13:828-51). In contrast, KRAS G12C mutations predominate in non-small cell lung cancer (NSCLC) comprising 11-16% of lung adenocarcinomas, and 2-5% of pancreatic and colorectal adenocarcinomas (Cox, A.D. et al. Nat. Rev. Drug Discov. (2014) 13:828-51). Genomic studies across hundreds of cancer cell lines have demonstrated that cancer cells harboring KRAS mutations are highly dependent on KRAS function for cell growth and survival (McDonald, R. et al. Cell 170 (2017): 577- 592). The role of mutant KRAS as an oncogenic driver is further supported by extensive in vivo experimental evidence showing mutant KRAS is required for early tumour onset and maintenance in animal models (Cox, A.D. et al. Nat Rev Drug Discov (2014) 13:828-51).

Taken together, these findings suggest that KRAS mutations play a critical role in human cancers; development of inhibitors targeting mutant KRAS may therefore be useful in the clinical treatment of diseases that are characterized by a KRAS mutation.

Scheme 1 Compounds of formula 1-22 and 1-23 can be prepared via the synthetic route outlined in Scheme 1. Starting material 1-1 can undergo iodination with /V-iodo-succinimide (NIS) to form intermediate 1-2, which can then be subjected to carbonylation conditions with palladium catalyst and carbon monoxide in methanol to give intermediate 1-3. Treating intermediate 1-3 with ethyl malonyl chloride can afford compound 1-4, which can cyclize to give intermediate 1-5 in the presence of sodium ethoxide.

Nitration of compound 1-6 with nitric acid in acetic acid can deliver the nitro compound 1-7, which can be converted into the common intermediate 1-8 by POCh. A SNAr reaction of intermediate 1-8 with amine 1-9 (PG is an appropriate protecting group, such as Boc) can be carried out to generate compound 1-10, which can undergo another SNAr reaction with sodium thiomethoxide to yield intermediate 1-11. Compound 1-13 can be prepared from intermediate 1-11 by Boc protection and subsequent reduction of the nitro group to NH2 with reducing agents (e.g. Fe powder or sodium dithionite). The NH2 group of compound 1-13 can be converted to iodo atom when subjected to Sandmeyer reaction conditions to give intermediate 1-14, of which the Boc group can be removed by trifluoroacetic acid to deliver compound 1-15. A cross-coupling reaction between 1-15 and alkynes of formula 1-16, in which X is a hydrogen atom or an appropriately substituted metal [e.g. Sn(Alkyl)s] under standard Sonogashira coupling conditions (e.g., in the presence of a palladium catalyst), or standard Stille cross-coupling conditions (e.g., in the presence of a palladium catalyst), can generate intermediate 1-17, which can cyclize to form the pyrrole ring in the presence of a gold catalyst to deliver compound 1-18. Intermediate 1-20 can be prepared by a crosscoupling reaction between 1-18 and an adduct of formula 1-19, in which Cy ¹ -M is a boronic acid, boronic ester or an appropriately substituted metal reagent [e.g., M is B(OR)2, Sn(Alkyl)s, or Zn-Hal], or a NH-containing heterocycle, under standard Suzuki cross-coupling conditions (e.g., in the presence of a palladium catalyst and a suitable base), or standard Stille cross-coupling conditions (e.g., in the presence of a palladium catalyst), or standard Negishi cross-coupling conditions (e.g., in the presence of a palladium catalyst), or standard Buchwald-Hartwig cross-coupling conditions (e.g., in the presence of a palladium catalyst and a suitable base).

A SNAr reaction of intermediate 1-8 with amine 3-1 (PG is an appropriate protecting group, such as Boc) can be carried out to generate compound 3-2, which can undergo another SNAr reaction with a nucleophile Nu-H [e.g. amine, alcohol, or phenol] to yield intermediate 3-3. Compound 3-4 can be prepared from intermediate 3-3 by reduction of the nitro group to NH2 with reducing agents (e.g. Fe powder or sodium dithionite). Cyclization between 3-4 and an aldehyde 3-5 can generate intermediate 3-6, which can undergo a cross-coupling reaction with an adduct of formula 3-7, in which Cy ¹ -M is a boronic acid, boronic ester or an appropriately substituted metal reagent [e.g., M is B(OR)2, Sn(Alkyl)s, or Zn-Hal], or a NH-containing heterocycle, under standard Suzuki cross-coupling conditions (e.g., in the presence of a palladium catalyst and a suitable base), or standard Stille cross-coupling conditions (e.g., in the presence of a palladium catalyst), or standard Negishi cross-coupling conditions (e.g., in the presence of a palladium catalyst), or standard Buchwald-Hartwig cross-coupling conditions (e.g., in the presence of a palladium catalyst and a suitable base), to yield compound 3-8. Removal of the protecting group in 3-8 can afford the desired product 3-9. The free NH group in 3-9 can also be capped by various moieties as illustrated in Scheme 1.

Scheme 5. Halogenation of starting material 5-1 with an appropriate reagent, such as N- chloro-succinimide (NCS), /V-Bromo-succinimide (NBS), or /V-lodo-succinimide (NIS), affords intermediate 5-2 (Hal is a halide, such as F, Cl, Br, or I). Compound 5-4 can then be prepared by a amide coupling reaction of 5-2 with appropriate acyl chloride 5-3. Condensation of 5-4 followed by decarboxylation can deliver intermediate 5-6. Nitration of intermediate 5-6 gives the nitro adduct 5-7, which upon treatment with a reagent, such as POCh, yields intermediate 5-8. A SNAr reaction of 5-8 with an amine of formula 5-9 (PG is an appropriate protecting group, such as Boc) followed by a second SNAr with another nucleophile generate compound 5-11. The nitro functionality in 5-11 can be reduced to -NH2 under suitable conditions (such as using Fe in acetic acid), followed by a cyclization reaction to deliver compound 5-13. Compound 5-19 can be prepared via sequential coupling reactions (and/or SNAr reactions) of intermediate 5-13 using appropriate coupling partners, in which Cy ¹ -M is a boronic acid, boronic ester or an appropriately substituted metal reagent [e.g., M is B(0R)2, Sn(Alkyl)3, or Zn-Hal, Li, Na, K], or a NH-containing heterocycle, under standard Suzuki Cross-Coupling conditions {e.g., in the presence of a palladium catalyst and a suitable base), or standard Stille cross-coupling conditions (e.g., in the presence of a palladium catalyst), or standard Negishi cross-coupling conditions (e.g., in the presence of a palladium catalyst), or standard Buchwald-Hartwig cross-coupling conditions (e.g., in the presence of a palladium catalyst and a suitable base). Removal of the protecting group in 5- 19 affords the desired product 5-20. The free NH group in 5-20 can also be capped by various moieties as illustrated in Scheme 1. The order of the above described chemical reactions can be rearranged or omitted as appropriate to suit the preparation of different analogues.

KRAS Protein

The Ras family is comprised of three members: KRAS, NRAS and HRAS. RAS mutant cancers account for about 25% of human cancers. KRAS is the most frequently mutated isoform in human cancers: 85% of all RAS mutations are in KRAS, 12% in NRAS, and 3% in HRAS (Simanshu, D. et al. Cell 170.1 (2017):17-33). KRAS mutations are prevalent amongst the top three most deadly cancer types: pancreatic (97%), colorectal (44%), and lung (30%) (Cox, A.D. et al. Nat Rev Drug Discov (2014) 13:828-51). The majority of RAS mutations occur at amino acid residues/codons 12, 13, and 61; Codon 12 mutations are most frequent in KRAS. The frequency of specific mutations varied between RAS genes and G12D mutations are most predominant in KRAS whereas Q61R and G12R mutations are most frequent in NRAS and HRAS. Furthermore, the spectrum of mutations in a RAS isoform differs between cancer types. For example, KRAS G12D mutations predominate in pancreatic cancers (51%), followed by colorectal adenocarcinomas (45%) and lung cancers (17%) (Cox, A.D. et al. Nat Rev Drug Discov (2014) 13:828-51). In contrast, KRAS G12C mutations predominate in non-small cell lung cancer (NSCLC) comprising 11-16% of lung adenocarcinomas (nearly half of mutant KRAS is G12C), as well as 2-5% of pancreatic and colorectal adenocarcinomas, respectively (Cox, A.D. et al. Nat. Rev. Drug Discov. (2014) 13:828-51). Using shRNA knockdown thousands of genes across hundreds of cancer cell lines, genomic studies have demonstrated that cancer cells exhibiting KRAS mutations are highly dependent on KRAS function for cell growth (McDonald, R. et al. Cell 170 (2017): 577-592). Taken together, these findings suggested that KRAS mutations play a critical role in human cancers, therefore development of the inhibitors targeting mutant KRAS may be useful in the clinical treatment of diseases that have characterized by a KRAS mutation. Methods of Use

The cancer types in which KRAS harboring G12C, G12V, and G12D mutations are implicated include, but are not limited to: carcinomas (e.g., pancreatic, colorectal, lung, bladder, gastric, esophageal, breast, head and neck, cervical skin, thyroid); hematopoietic malignancies (e.g., myeloproliferative neoplasms (MPN), myelodysplastic syndrome (MDS), chronic and juvenile myelomonocytic leukemia (CMML and JMML), acute myeloid leukemia (AML), acute lymphocytic leukemia (ALL) and multiple myeloma (MM)); and other neoplasms (e.g., glioblastoma and sarcomas). In addition, KRAS mutations were found in acquired resistance to anti-EGFR therapy (Knickelbein, K.et al. Genes & Cancer, (2015): 4- 12). KRAS mutations were found in immunological and inflammatory disorders (Fernandez- Medarde, A. et al. Genes & Cancer, (2011): 344-358) such as Ras-associated lymphoproliferative disorder (RALD) or juvenile myelomonocytic leukemia (JMML) caused by somatic mutations of KRAS or NRAS.

Combination Therapies I. Cancer therapies

Cancer cell growth and survival can be impacted by dysfunction in multiple signaling pathways. Thus, it is useful to combine different enzyme/protein/receptor inhibitors, exhibiting different preferences in the targets which they modulate the activities of, to treat such conditions. Targeting more than one signaling pathway (or more than one biological molecule involved in a given signaling pathway) may reduce the likelihood of drug-resistance arising in a cell population, and/or reduce the toxicity of treatment.

One or more additional pharmaceutical agents such as, for example, chemotherapeutics, anti-inflammatory agents, steroids, immunosuppressants, immune- oncology agents, metabolic enzyme inhibitors, chemokine receptor inhibitors, and phosphatase inhibitors, as well as targeted therapies such as Bcr-Abl, Flt-3, EGFR, HER2, JAK, c-MET, VEGFR, PDGFR, c-Kit, IGF-1 R, RAF, FAK, and CDK4/6 kinase inhibitors such as, for example, those described in WO 2006/056399 can be used in combination with the compounds of the present disclosure for treatment of CDK2-associated diseases, disorders or conditions. Other agents such as therapeutic antibodies can be used in combination with the compounds of the present disclosure for treatment of CDK2-associated diseases, disorders or conditions. The one or more additional pharmaceutical agents can be administered to a patient simultaneously or sequentially.

In some embodiments, the polyethylene oxide is polyethylene oxide WSR 1105 (e.g., Polyox WSR 1105™).

In some embodiments, a wet granulation process is used to produce the composition. In some embodiments, a dry granulation process is used to produce the composition.

The compositions can be formulated in a unit dosage form, each dosage containing from about 5 to about 1,000 mg (1 g), more usually about 100 mg to about 500 mg, of the active ingredient. In some embodiments, each dosage contains about 10 mg of the active ingredient. In some embodiments, each dosage contains about 50 mg of the active ingredient. In some embodiments, each dosage contains about 25 mg of the active ingredient. The term “unit dosage forms” refers to physically discrete units suitable as unitary dosages for human subjects and other mammals, each unit containing a predetermined quantity of active material calculated to produce the desired therapeutic effect, in association with a suitable pharmaceutical excipient.

The components used to formulate the pharmaceutical compositions are of high purity and are substantially free of potentially harmful contaminants (e.g., at least National Food grade, generally at least analytical grade, and more typically at least pharmaceutical grade). Particularly for human consumption, the composition is preferably manufactured or formulated under Good Manufacturing Practice standards as defined in the applicable regulations of the U.S. Food and Drug Administration. For example, suitable formulations may be sterile and/or substantially isotonic and/or in full compliance with all Good Manufacturing Practice regulations of the U.S. Food and Drug Administration.

The active compound may be effective over a wide dosage range and is generally administered in a therapeutically effective amount. It will be understood, however, that the amount of the compound actually administered will usually be determined by a physician, according to 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 the patient's symptoms and the like.

The therapeutic dosage of a compound of the present disclosure can vary according to, e.g., the particular use for which the treatment is made, the manner of administration of the compound, the health and condition of the patient, and the judgment of the prescribing physician. The proportion or concentration of a compound provided herein in a pharmaceutical composition can vary depending upon a number of factors including dosage, chemical characteristics (e.g., hydrophobicity), and the route of administration. For example, the compounds disclosed herein can be provided in an aqueous physiological buffer solution containing about 0.1 to about 10% w/v of the compound for parenteral administration. Some typical dose ranges are from about 1 pg/kg to about 1 g/kg of body weight per day. In some embodiments, the dose range is from about 0.01 mg/kg to about 100 mg/kg of body weight per day. The dosage is likely to depend on such variables as the type and extent of progression of the disease or disorder, the overall health status of the particular patient, the relative biological efficacy of the compound selected, formulation of the excipient, and its route of administration. Effective doses can be extrapolated from dose-response curves derived from in vitro or animal model test systems.

For preparing solid compositions such as tablets, the principal active ingredient is mixed with a pharmaceutical excipient to form a solid preformulation composition containing a homogeneous mixture of a compound of the present disclosure. When referring to these preformulation compositions as homogeneous, the active ingredient is typically dispersed evenly throughout the composition so that the composition can be readily subdivided into equally effective unit dosage forms such as tablets, pills and capsules. This solid preformulation is then subdivided into unit dosage forms of the type described above containing from, e.g., about 0.1 to about 1000 mg of the active ingredient of the present disclosure.

The tablets or pills of the present disclosure can be coated or otherwise compounded to provide a dosage form affording the advantage of prolonged action. For example, the tablet or pill can comprise an inner dosage and an outer dosage component, the latter being in the form of an envelope over the former. The two components can be separated by an enteric layer which serves to resist disintegration in the stomach and permit the inner component to pass intact into the duodenum or to be delayed in release. A variety of materials can be used for such enteric layers or coatings, such materials including a number of polymeric acids and mixtures of polymeric acids with such materials as shellac, cetyl alcohol and cellulose acetate.

The liquid forms in which the compounds and compositions of the present disclosure can be incorporated for administration orally or by injection include aqueous solutions, suitably flavored syrups, aqueous or oil suspensions, and flavored emulsions with edible oils such as cottonseed oil, sesame oil, coconut oil, or peanut oil, as well as elixirs and similar pharmaceutical vehicles.

Compositions for inhalation or insufflation include solutions and suspensions in pharmaceutically acceptable, aqueous or organic solvents, or mixtures thereof, and powders. The liquid or solid compositions may contain suitable pharmaceutically acceptable excipients as described supra. In some embodiments, the compositions are administered by the oral or nasal respiratory route for local or systemic effect. Compositions can be nebulized by use of inert gases. Nebulized solutions may be breathed directly from the nebulizing device or the nebulizing device can be attached to a face mask, tent, or intermittent positive pressure breathing machine. Solution, suspension, or powder compositions can be administered orally or nasally from devices which deliver the formulation in an appropriate manner.

Topical formulations can contain one or more conventional carriers. In some embodiments, ointments can contain water and one or more hydrophobic carriers selected from, e.g., liquid paraffin, polyoxyethylene alkyl ether, propylene glycol, white Vaseline, and the like. Carrier compositions of creams can be based on water in combination with glycerol and one or more other components, e.g., glycerinemonostearate, PEG- glycerinemonostearate and cetylstearyl alcohol. Gels can be formulated using isopropyl alcohol and water, suitably in combination with other components such as, e.g., glycerol, hydroxyethyl cellulose, and the like. In some embodiments, topical formulations contain at least about 0.1 , at least about 0.25, at least about 0.5, at least about 1 , at least about 2 or at least about 5 wt % of the compound disclosed herein. The topical formulations can be suitably packaged in tubes of, e.g., 100 g which are optionally associated with instructions for the treatment of the select indication, e.g., psoriasis or other skin condition.

The amount of compound or composition administered to a patient will vary depending upon what is being administered, the purpose of the administration, such as prophylaxis or therapy, the state of the patient, the manner of administration and the like. In therapeutic applications, compositions can be administered to a patient already suffering from a disease in an amount sufficient to cure or at least partially arrest the symptoms of the disease and its complications. Effective doses will depend on the disease condition being treated as well as by the judgment of the attending clinician depending upon factors such as the severity of the disease, the age, weight and general condition of the patient and the like.

The compositions administered to a patient can be in the form of pharmaceutical compositions described above. These compositions can be sterilized by conventional sterilization techniques, or may be sterile filtered. Aqueous solutions can be packaged for use as is, or lyophilized, the lyophilized preparation being combined with a sterile aqueous carrier prior to administration. The pH of the compound preparations typically will be between 3 and 11 , more preferably from 5 to 9 and most preferably from 7 to 8. It will be understood that use of certain of the foregoing excipients, carriers or stabilizers will result in the formation of pharmaceutical salts.

The therapeutic dosage of a compound of the present disclosure can vary according to, e.g., the particular use for which the treatment is made, the manner of administration of the compound, the health and condition of the patient, and the judgment of the prescribing physician. The proportion or concentration of a compound provided herein in a pharmaceutical composition can vary depending upon a number of factors including dosage, chemical characteristics (e.g., hydrophobicity), and the route of administration. For example, the compounds of the present disclosure can be provided in an aqueous physiological buffer solution containing about 0.1 to about 10% w/v of the compound for parenteral administration. Some typical dose ranges are from about 1 pg/kg to about 1 g/kg of body weight per day. In some embodiments, the dose range is from about 0.01 mg/kg to about 100 mg/kg of body weight per day. The dosage is likely to depend on such variables as the type and extent of progression of the disease or disorder, the overall health status of the particular patient, the relative biological efficacy of the compound selected, formulation of the excipient, and its route of administration. Effective doses can be extrapolated from doseresponse curves derived from in vitro or animal model test systems.

Labeled Compounds and Assay Methods

Another aspect of the present disclosure relates to labeled compounds of the disclosure (radio-labeled, fluorescent-labeled, etc.) that would be useful not only in imaging techniques but also in assays, both in vitro and in vivo, for localizing and quantitating KRAS protein in tissue samples, including human, and for identifying KRAS ligands by inhibition binding of a labeled compound. Substitution of one or more of the atoms of the compounds of the present disclosure can also be useful in generating differentiated ADME (Adsorption, Distribution, Metabolism and Excretion). Accordingly, the present disclosure includes KRAS binding assays that contain such labeled or substituted compounds. The present disclosure further includes isotopically-labeled compounds of the disclosure. An “isotopically” or “radio-labeled” compound is a compound of the disclosure where one or more atoms are replaced or substituted by an atom having an atomic mass or mass number different from the atomic mass or mass number typically found in nature (i.e., naturally occurring). Suitable radionuclides that may be incorporated in compounds of the present disclosure include but are not limited to ² H (also written as D for deuterium), ³ H (also written as T for tritium), ¹¹ C, ¹³ C, ¹⁴ C, ¹³ N, ¹⁵ N, ¹⁵ O, ¹⁷ O, ¹⁸ 0, ¹⁸ F, ³⁵ S, ³⁶ CI, ⁸² Br, ⁷⁵ Br, ⁷⁶ Br, ⁷⁷ Br, ¹²³ l, ¹²⁴ l, ¹²⁵ l and ¹³¹ 1. For example, one or more hydrogen atoms in a compound of the present disclosure can be replaced by deuterium atoms (e.g., one or more hydrogen atoms of a Ci-6 alkyl group of Formula I, II, or any formulae provided herein can be optionally substituted with deuterium atoms, such as -CDs being substituted for -CHs). In some embodiments, alkyl groups in Formula I, II, or any formulae provided herein can be perdeuterated.

One or more constituent atoms of the compounds presented herein can be replaced or substituted with isotopes of the atoms in natural or non-natural abundance. In some embodiments, the compound includes at least one deuterium atom. In some embodiments, the compound includes two or more deuterium atoms. In some embodiments, the compound includes 1-2, 1-3, 1-4, 1-5, or 1-6 deuterium atoms. In some embodiments, all of the hydrogen atoms in a compound can be replaced or substituted by deuterium atoms.

Synthetic methods for including isotopes into organic compounds are known in the art (Deuterium Labeling in Organic Chemistry by Alan F. Thomas (New York, N.Y., Appleton- Century-Crofts, 1971 ; The Renaissance of H/D Exchange by Jens Atzrodt, Volker Derdau, Thorsten Fey and Jochen Zimmermann, Angew. Chem. Int. Ed. 2007, 7744-7765; The Organic Chemistry of Isotopic Labelling by James R. Hanson, Royal Society of Chemistry, 2011). Isotopically labeled compounds can be used in various studies such as NMR spectroscopy, metabolism experiments, and/or assays.

Substitution with heavier isotopes, such as deuterium, may afford certain therapeutic advantages resulting from greater metabolic stability, for example, increased in vivo half-life or reduced dosage requirements, and hence may be preferred in some circumstances, (see e.g., A. Kerekes et. al. J. Med. Chem. 2011 , 54, 201-210; R. Xu et. al. J. Label Compd. Radiopharm. 2015, 58, 308-312). In particular, substitution at one or more metabolism sites may afford one or more of the therapeutic advantages.

The radionuclide that is incorporated in the instant radio-labeled compounds will depend on the specific application of that radio-labeled compound. For example, for in vitro adenosine receptor labeling and competition assays, compounds that incorporate ³ H, ¹⁴ C, ⁸² Br, ¹²⁵ l, ¹³¹ l or ³⁵ S can be useful. For radio-imaging applications ¹¹ C, ¹⁸ F, ¹²⁵ l, ¹²³ l, ¹²⁴ l, ¹³¹ l, ⁷⁵ Br, ⁷⁶ Br or ⁷⁷ Br can be useful. It is understood that a “radio-labeled” or “labeled compound” is a compound that has incorporated at least one radionuclide. In some embodiments, the radionuclide is selected from ³ H, ¹⁴ C, ¹²⁵ l, ³⁵ S and ⁸² Br.

The present disclosure can further include synthetic methods for incorporating radioisotopes into compounds of the disclosure. Synthetic methods for incorporating radioisotopes into organic compounds are well known in the art, and an ordinary skill in the art will readily recognize the methods applicable for the compounds of disclosure.

A labeled compound of the present disclosure can be used in a screening assay to identify and/or evaluate compounds. For example, a newly synthesized or identified compound (/.e., test compound) which is labeled can be evaluated for its ability to bind a KRAS protein by monitoring its concentration variation when contacting with the KRAS, through tracking of the labeling. For example, a test compound (labeled) can be evaluated for its ability to reduce binding of another compound which is known to bind to a KRAS protein (/.e., standard compound). Accordingly, the ability of a test compound to compete with the standard compound for binding to the KRAS protein directly correlates to its binding affinity. Conversely, in some other screening assays, the standard compound is labeled and test compounds are unlabeled. Accordingly, the concentration of the labeled standard compound is monitored in order to evaluate the competition between the standard compound and the test compound, and the relative binding affinity of the test compound is thus ascertained.

Kits

The present disclosure also includes pharmaceutical kits useful, e.g., in the treatment or prevention of diseases or disorders associated with the activity of KRAS, such as cancer or infections, which include one or more containers containing a pharmaceutical composition comprising a therapeutically effective amount of a compound of Formula I, II, or any of the embodiments thereof. Such kits can further include one or more of various conventional pharmaceutical kit components, such as, e.g., containers with one or more pharmaceutically acceptable carriers, additional containers, etc., as will be readily apparent to those skilled in the art. Instructions, either as inserts or as labels, indicating quantities of the components to be administered, guidelines for administration, and/or guidelines for mixing the components, can also be included in the kit.

The present disclosure will be described in greater detail by way of specific examples. The following examples are offered for illustrative purposes, and are not intended to limit the disclosure in any manner. Those of skill in the art will readily recognize a variety of non-critical parameters which can be changed or modified to yield essentially the same results. The compounds of the Examples have been found to inhibit the activity of KRAS according to at least one assay described herein.

Example A. GDP-GTP exchange assay.

The inhibitor potency of the exemplified compounds was determined in a fluorescence based guanine nucleotide exchange assay, which measures the exchange of bodipy-GDP (fluorescently labeled GDP) for GppNHp (Non-hydrolyzable GTP analog) to generate the active state of KRAS in the presence of SOS1 (guanine nucleotide exchange factor). Inhibitors were serially diluted in DMSO and a volume of 0.1 L was transferred to the wells of a black low volume 384-well plate. 5 L/well volume of bodipy-loaded KRAS G12D diluted to 2.5 nM in assay buffer (25 mM Hepes pH 7.5, 50 mM NaCI, 10 mM MgCh and 0.01% Brij-35) was added to the plate and pre-incubated with inhibitor for 4 hours at ambient temperature. Appropriate controls (enzyme with no inhibitor or with a G12D inhibitor) were included on the plate. The exchange was initiated by the addition of a 5 L/well volume containing 1 mM GppNHp and 300 nM SOS1 in assay buffer. The 10 L/well reaction concentration of the bodipy-loaded KRAS G12D, GppNHp, and SOS1 were 2.5 nM, 500 uM, and 150 nM, respectively. The reaction plates were incubated at ambient temperature for 2 hours, a time estimated for complete GDP-GTP exchange in the absence of inhibitor. For the KRAS G12V mutant, similar guanine nucleotide exchange assays were used with 2.5nM as final concentration for the bodipy loaded KRAS proteins and 3 hours incubation after adding GppNHp-SOS1 mixture. A cyclic peptide described to selectively bind G12D mutant (Sakamoto et al., BBRC 484.3 (2017), 605-611) or internal compounds with confirmed binding were used as positive controls in the assay plates. Fluorescence intensities were measured on a PheraStar plate reader instrument (BMG Labtech) with excitation at 485 nm and emission at 520 nm.

Table 4 Example G: In vivo efficacy studies

Mia-Paca-2 human pancreatic cancer cells are obtained from the American Type Culture Collection and maintained in RPMI media supplemented with 10% FBS. For efficacy studies experiments, 5 x 10 ⁶ Mia-Paca-2 cells are inoculated subcutaneously into the right hind flank of 6- to 8-week-old BALB/c nude mice (Charles River Laboratories, Wilmington, MA, USA). When tumor volumes are approximately 150-250 mm3, mice are randomized by tumor volume and compounds are orally administered. Tumor volume is calculated using the formula (L x W ² )^, where L and W refer to the length and width dimensions, respectively. Tumor growth inhibition is calculated using the formula (1 - (VT/VC)) ^X 100, where VT is the tumor volume of the treatment group on the last day of treatment, and Vc is the tumor volume of the control group on the last day of treatment. Two-way analysis of variance with Dunnett’s multiple comparisons test is used to determine statistical differences between treatment groups (GraphPad Prism). Mice are housed at 10-12 animals per cage, and are provided enrichment and exposed to 12-hour light/dark cycles. Mice whose tumor volumes exceeded limits (10% of body weight) are humanely euthanized by CO2 inhalation. Animals are maintained in a barrier facility fully accredited by the Association for Assessment and Accreditation of Laboratory Animal Care, International. All of the procedures are conducted in accordance with the US Public Service Policy on Human Care and Use of Laboratory Animals and with Incyte Animal Care and Use Committee Guidelines.
