Description

Technical Field

[0001] This specification provides KRAS G12C inhibitors, compositions thereof, and methods of using the same. These inhibitors are useful for treating a number of disorders including pancreatic cancer, colorectal cancer, and lung cancer.

Background Art

[0002] KRAS gene mutations are frequently found in pancreatic cancer, lung adenocarcinoma, colorectal cancer, gallbladder cancer, thyroid cancer, and cholangiocarcinoma. KRAS mutations are also observed in about 25% of NSCLC patients, and some studies have shown that KRAS mutations are poor prognostic factors for NSCLC patients. Recently, it has been found that V-Ki-ras2 Kirsten rat sarcoma viral oncogene homolog (KRAS) mutations confer resistance to therapies targeting epidermal growth factor receptor (EGFR) in colorectal cancer. Therefore, important information for prescribing TKI therapy can be obtained from the mutation status of KRAS. In summary, there is a need for new drug therapies for patients with pancreatic cancer, lung adenocarcinoma, or colorectal cancer, especially for patients diagnosed with such cancers characterized by KRAS mutations, including those who show progression after chemotherapy.

[0072] The disclosed compounds This specification provides KRAS inhibitors having one of the structures of Formulas I-V, which are discussed in detail below.

[0073] The compounds disclosed herein include all pharmaceutically acceptable isotopically labeled compounds in which one or more atoms of the disclosed compounds are replaced with atoms having the same atomic number but different atomic mass or mass number than the atomic mass or mass number typically found in nature. Examples of isotopes that can be incorporated into the disclosed compounds include isotopes of hydrogen, carbon, nitrogen, oxygen, phosphorus, fluorine, chlorine, and iodine, such as 2 H, 3 H, 11 C, 13 C, 14 C, 13 N, 15 N, 15 O, 17 O, 18 O, 31 P, 32 P, 35 S, 18 F, 36 Cl, 123 I, and 125 I, and the like. These radiolabeled compounds can be useful, for example, in elucidating characteristics such as the site or mechanism of action, or the binding affinity for a pharmacologically important site of action, and thereby can assist in determining or measuring the effectiveness of a compound. Certain isotopically labeled compounds of the present disclosure, for example, those incorporating a radioactive isotope, are useful in the study of the tissue distribution of drugs and / or substrates. For such purposes, the radioactive isotopes tritium, i.e., 3 H, and carbon-14, i.e., 14C is particularly useful considering its ease of incorporation and its immediate detection means.

Appropriate formulations depend on the selected route of administration.

[0166] In the case of oral administration, suitable compositions can be easily formulated by combining the compounds disclosed herein with pharmaceutically acceptable excipients such as carriers well-known in the art. Such excipients and carriers enable the formulation of the compounds of the present application for oral ingestion by the patient to be treated in the form of tablets, pills, dragees, capsules, solutions, gels, syrups, slurries, suspensions, etc. Oral pharmaceutical preparations can be prepared by adding the compounds disclosed herein using solid excipients, optionally grinding the resulting mixture, adding suitable auxiliaries as necessary, and then processing the granule mixture to obtain tablets or dragee cores. Suitable excipients include, for example, fillers and cellulose preparations. Disintegrants can be added as necessary. A wide variety of formulations are well-known as pharmaceutically acceptable raw materials, and they can be, for example, binders for various formulations (e.g., natural polymers or synthetic polymers), lubricants, surfactants, sweeteners and flavoring agents, coating materials, preservatives, pigments, thickeners, adjuvants, antibacterial agents, antioxidants, and carriers.

[0167] When administering a therapeutically effective amount of the compounds disclosed herein orally, the composition is typically in solid form (e.g., tablets, capsules, pills, powders, or lozenges) or in liquid form (e.g., aqueous suspensions, solutions, elixirs, or syrups).

[0168] When administered in tablet form, the composition can further contain functional solids and / or solid carriers, such as gelatin or adjuvants. Tablets, capsules, and powders can contain from about 1% to about 95% of the compound, preferably from about 15% to about 90% of the compound.

[0169] When administered in liquid or suspension form, functional liquids and / or liquid carriers such as water, petroleum, or oils of animal or plant origin can be added. The composition in liquid form can further contain physiological saline, sugar alcohol solutions, dextrose or other sugar solutions, or glycols. When administered in liquid or suspension form, the composition can contain from about 0.5 to about 90% by weight of the disclosed compounds herein, preferably from about 1 to about 50% of the disclosed compounds herein. In one intended embodiment, the liquid carrier is non-aqueous or substantially non-aqueous. For administration in liquid form, the composition can be provided as an immediate-dissolving solid formulation that is dissolved or suspended immediately prior to administration.

[0170] When a therapeutically effective amount of the disclosed compounds herein is administered by intravenous injection, intradermal injection, or subcutaneous injection, the composition is in the form of a pyrogen-free parenterally acceptable aqueous solution. The preparation of such parenterally acceptable solutions should be considered with respect to pH, isotonicity, stability, etc., but these are within the skill of those in the art. Preferred compositions for intravenous injection, intradermal injection, or subcutaneous injection typically contain an isotonic vehicle in addition to the compounds disclosed herein. Such compositions can be prepared for administration as an aqueous solution of the free base or a pharmaceutically acceptable salt, suitably mixed with a surfactant such as hydroxypropylcellulose. Dispersions can also be prepared in glycerol, liquid polyethylene glycols, and mixtures thereof, as well as in oils. Under normal storage and use conditions, these preparations can optionally contain preservatives to prevent the growth of microorganisms.

[0171] Injectable compositions can include sterile aqueous solutions, suspensions, or dispersions, and sterile powders for the extemporaneous preparation of sterile injectable solutions, suspensions, or dispersions. In all embodiments, such forms must be in a sterile form and be fluids that can easily pass through a hypodermic needle. They must be stable under manufacturing and storage conditions and, optionally, be resistant to the contaminating action of microorganisms such as bacteria and fungi by including preservatives. The carrier can be, for example, a solvent or dispersion medium containing water, ethanol, polyols (such as glycerol, propylene glycol, and liquid polyethylene glycol, etc.), suitable mixtures thereof, and vegetable oils. In one intended embodiment, the carrier is non-aqueous or substantially non-aqueous. Suitable fluidity can be maintained, for example, by using coatings such as lecithin, by maintaining the required particle size of the compounds in the dispersion embodiments, and by using surfactants. Prevention of microbial action can be provided by various antibacterial and antifungal agents such as parabens, chlorobutanol, phenol, sorbic acid, thimerosal, etc. In many embodiments, it would be preferable to include isotonic agents such as sugars or sodium chloride. Sustained absorption of injectable compositions can be brought about by using agents that delay absorption, such as aluminum monostearate and gelatin, in the composition.

[0172] Sterile injectable solutions are prepared by incorporating the active compound in the required amount, optionally with other various aforementioned ingredients, into a suitable solvent and then filtering and sterilizing. Generally, dispersions are prepared by incorporating various sterile active ingredients into a sterile vehicle containing a base dispersion medium and other required ingredients from the above. In the case of embodiments of sterile powders for the preparation of sterile injectable solutions, the preferred preparation methods are the vacuum drying method and the freeze-drying method, which result in a powder obtained by adding the active ingredient and any further desired ingredients obtained from the previous sterile filtered solution.

[0173] Sustained release or controlled release formulations may be prepared to achieve controlled release of the active compound upon contact with body fluids in the gastrointestinal tract and to substantially maintain and be effective in the plasma level of the active compound. For example, release can be controlled by one or more of dissolution, diffusion, and ion exchange. Further, by making a controlled release formulation, absorption through saturable or rate-limiting pathways in the gastrointestinal tract can be enhanced. For example, for this purpose, the compound may be embedded in a polymeric matrix of a biodegradable polymer, a water-soluble polymer or a mixture of both, and optionally a suitable surfactant. In this case, embedding means incorporating fine particles into the matrix of the polymer. The controlled release formulation can also be obtained by encapsulating dispersed fine particles or emulsified microdroplets by known dispersion or emulsion coating techniques.

[0174] For administration by inhalation, the compounds of the present invention are conveniently delivered in the form of an aerosol spray presented from a pressurized pack or a nebulizer using a suitable propellant.

[0177] The compounds disclosed herein can also be formulated into rectal compositions such as suppositories or retention enemas (e.g., containing conventional suppository bases). In addition to the formulations described above, the compounds can be formulated as depot preparations. Such long-acting formulations can be administered by implantation (e.g., subcutaneously or intramuscularly) or intramuscular injection. Thus, for example, the compound can be formulated using a suitable polymeric substance or a hydrophobic substance (e.g., as an emulsion in an acceptable oil) or an ion exchange resin, or as a slightly insoluble derivative, e.g., as a slightly insoluble salt.

[0178] In particular, the compounds disclosed herein can be administered orally, buccally, or sublingually in the form of tablets containing excipients such as starch or lactose, or in capsules or ovules (mixtures or single agents with excipients), or in the form of elixirs or suspensions containing flavoring or coloring agents. Such liquid preparations can be prepared using pharmaceutically acceptable additives such as suspending agents. The compound can also be administered parenterally, e.g., by intravenous, intramuscular, subcutaneous, or intracoronary injection.

The frequency of administration may also depend on the pharmacodynamic effect on the arterial oxygen pressure. However, the most preferred dosage can be adjusted to suit the individual subject, which can be understood and determined by those skilled in the art without undue experimentation. In this case, typically, an adjustment of the standard dosage (for example, a reduction in dosage if the patient has a low body weight) is made.

[0183] Although individual needs vary, determining the optimal range of the effective amount of a compound is within the skill of those in the art. For example, when administered to humans in the curative or prophylactic treatment of the conditions and disorders specified herein, typical dosages of the compounds of the invention are from about 0.05 mg / kg / day to about 50 mg / kg / day, for example, at least 0.05 mg / kg, at least 0.08 mg / kg, at least 0.1 mg / kg, at least 0.2 mg / kg, at least 0.3 mg / kg, at least 0.4 mg / kg, or at least 0.5 mg / kg, and preferably 50 mg / kg or less, 40 mg / kg or less, 30 mg / kg or less, 20 mg / kg or less, or 10 mg / kg or less, which can be, for example, from about 2.5 mg / day (0.5 mg / kg × 5 kg) to about 5000 mg / day (50 mg / kg × 100 kg). For example, the dosage of the compound can be from about 0.1 mg / kg / day to about 50 mg / kg / day, from about 0.05 mg / kg / day to about 10 mg / kg / day, from about 0.05 mg / kg / day to about 5 mg / kg / day, from about 0.05 mg / kg / day to about 3 mg / kg / day, from about 0.07 mg / kg / day to about 3 mg / kg / day, from about 0.09 mg / kg / day to about 3 mg / kg / day, from about 0.05 mg / kg / day to about 0.1 mg / kg / day, from about 0.1 mg / kg / day to about 1 mg / kg / day, from about 1 mg / kg / day to about 10 mg / kg / day, from about 1 mg / kg / day to about 5 mg / kg / day, from about 1 mg / kg / day to about 3 mg / kg / day, from about 3 mg / day to about 500 mg / day, from about 5 mg / day to about 250 mg / day, from about 10 mg / day to about 100 mg / day, from about 3 mg / day to about 10 mg / day, or from about 100 mg / day to about 250 mg / day. Such dosages may be administered in a single dose or divided into multiple doses.

[0184] Methods of using KRAS G12C inhibitors The present disclosure provides a method of inhibiting RAS-mediated cell signaling, which comprises contacting cells with an effective amount of one or more of the disclosed compounds herein.

[0242] The compounds described herein can be used in combination with the agents disclosed herein or other suitable agents depending on the condition to be treated. Thus, in some embodiments, one or more compounds of the disclosure will be co-administered with other agents as described above. When the compounds described herein are used in combination therapy, they are administered simultaneously or separately with the second agent. Such co-administration can include simultaneous administration of the two agents in the same dosage form, simultaneous administration in individual dosage forms, and separate administration. That is, the compounds described herein and any of the above agents can be formulated together in the same dosage form for simultaneous administration. Alternatively, the disclosed compounds and any of the above agents can be co-administered, where both agents are included in separate formulations. In another alternative, any of the above agents can be administered after administration of the compounds of the disclosure, or vice versa. In some embodiments of the separate administration protocol, the disclosed compounds and any of the above agents are administered at intervals of minutes, or hours, or days.

[0243] In one aspect of the invention, treatment of a disease / condition using a combination of pharmaceutically active compounds that can be administered separately is contemplated, and the invention further relates to packaging separate pharmaceutical compositions in kit form. The kit includes two separate pharmaceutical compositions, namely a compound of the invention and a second pharmaceutical compound. The kit includes a container for holding the separate compositions, such as a divided bottle or a divided foil packet. Further examples of containers include syringes, boxes, and bags. In some embodiments, the kit includes instructions for use of the separate components. The kit form is particularly convenient when it is preferred to administer the separate components in different dosage forms (e.g., oral and parenteral dosage forms), at different dosing intervals, or when the prescribing medical professional desires a titration of the individual components of the combination.

Examples

[0244] Method 1 Example 1-1: 1-(4-(6-(2-Bromo-5-hydroxyphenyl)-5-chloro-7-fluorobenzo[c]isothiazol-3-yl)piperazin-1-yl)prop-2-en-1-one

Chemical Structure

[0245] Step 2: 2-Amino-4-bromo-5-chloro-3-fluorobenzamide (Intermediate B). A mixed N,N-dimethylformamide solution (30 mL) of 2-amino-4-bromo-5-chloro-3-fluorobenzoic acid (Intermediate A, 3.96 g, 14.7 mmol) and TBTU (4.97 g, 15.5 mmol, Advanced ChemTech, Louisville, KY, USA) was sequentially added with ammonium chloride (1.10 g, 20.6 mmol) and diisopropylethylamine (5.13 mL, 29.5 mmol). The resulting mixture was stirred at room temperature for 30 minutes. Then, the reaction mixture was added to a saturated aqueous sodium bicarbonate solution and stirred for 15 minutes. The resulting precipitate was collected by filtration, washed with water, and dried under vacuum to obtain 2-amino-4-bromo-5-chloro-3-fluorobenzamide. 1 H NMR (400 MHz, DMSO-d6) δ 8.03 (1H, br s), 7.72 (1H, d, J = 2.0 Hz), 7.47 (1H, br s), 6.86 (2H, s). 19 F NMR (376 MHz, DMSO-d6) δ -120.79 (1F, s). m / z (ESI, +ve) 268.9 (M+H) + 。

[0246] Step 3: 2-Amino-4-bromo-5-chloro-3-fluorobenzothioamide Lawesson's reagent (2.81 g, 6.95 mmol) was added to a THF solution (77 mL) of 2-amino-4-bromo-5-chloro-3-fluorobenzamide (Intermediate B, 3.10 g, 11.59 mmol). The resulting mixture was stirred at room temperature for 1 hour. Then, the reaction mixture was diluted with EtOAc (75 mL) and washed successively with 2M aqueous HCl solution (50 mL), saturated aqueous sodium bicarbonate solution (50 mL), and brine (50 mL). Then, the organic extract was dried over Na2SO4, collected by filtration, and concentrated under reduced pressure. The residue was purified by chromatography (silica gel, DCM containing 0 - 3% MeOH) to obtain 2-amino-4-bromo-5-chloro-3-fluorobenzothioamide: 11H NMR (400 MHz, DMSO-d6) δ 9.93 - 10.15 (1H, m), 9.63 (1H, br s), 7.28 (1H, d, J = 1.96 Hz), 6.34 (2H, s). 19 19F NMR (376 MHz, DMSO-d6) δ -119.52 (1 F, s). m / z (ESI, +ve) 284.8 (M+H) + .
