The present invention concerns compounds, compositions and methods for the treatment of cancer.
Acute Lymphoblastic Leukemia (ALL) is the most common malignancy in children and common varieties are cured by chemotherapy in 75%-85% of the cases. Collectively the less common T cell and rare B cell subsets represent less than 2000 cases yearly and thus can be classified as a rare disease; these subsets have a poorer prognosis. Unfortunately with either subset, resistance to and relapse from therapy is a major cause of pediatric cancer death. In addition, ALL chemotherapies can cause late complications that are increasingly recognized in pediatric survivor populations. In fact, in pediatric cancer survivors, the incidence of severe late effects (neurocognitive sequelae, auditory complications, cardiovascular dysfunction, gastrointestinal/hepatic dysfunction, growth delay, secondary malignancies, and infertility) directly related to therapy is approximately 25%. A better understanding of therapeutic resistance and its reversal could not only help those who relapse but may help lower the dose of chemotherapy needed in ALL patients thus reducing long-term toxicity for future survivors.
The ectopic expression of Mer receptor tyrosine kinase (Mer) has been identified as a tumor cell survival gene product in Acute Lymphoblastic Leukemia (ALL) cells and a potential cause of ALL chemoresistance. Hence, we investigated whether the development of small molecule Mer inhibitors was possible.

“Treat” as used herein refers to any type of treatment that imparts a benefit to a patient afflicted with a disease, including improvement in the condition of the patient (e.g., in one or more symptoms), delay in the progression of the disease, delay in onset of the disease, etc.
“Pharmaceutically acceptable” as used herein means that the compound or composition is suitable for administration to a subject to achieve the treatments described herein, without unduly deleterious side effects in light of the severity of the disease and necessity of the treatment.
Active compounds of the present invention may optionally be administered in conjunction with other compounds useful in the treatment of cancer. The other compounds may optionally be administered concurrently. As used herein, the word “concurrently” means sufficiently close in time to produce a combined effect (that is, concurrently may be simultaneously, or it may be two or more events occurring within a short time period before or after each other).

Active compounds as described herein can be prepared in accordance with known procedures, or variations thereof that will be apparent to those skilled in the art.
2. Pharmaceutical Formulations.
The active compounds described above may be formulated for administration in a pharmaceutical carrier in accordance with known techniques. See, e.g., Remington, The Science And Practice of Pharmacy (9th Ed. 1995). In the manufacture of a pharmaceutical formulation according to the invention, the active compound (including the physiologically acceptable salts thereof) is typically admixed with, inter alia, an acceptable carrier. The carrier must, of course, be acceptable in the sense of being compatible with any other ingredients in the formulation and must not be deleterious to the patient. The carrier may be a solid or a liquid, or both, and is preferably formulated with the compound as a unit-dose formulation, for example, a tablet, which may contain from 0.01 or 0.5% to 95% or 99% by weight of the active compound. One or more active compounds may be incorporated in the formulations of the invention, which may be prepared by any of the well known techniques of pharmacy comprising admixing the components, optionally including one or more accessory ingredients.
The formulations of the invention include those suitable for oral, rectal, topical, buccal (e.g., sub-lingual), vaginal, parenteral (e.g., subcutaneous, intramuscular, intradermal, or intravenous), topical (i.e., both skin and mucosal surfaces, including airway surfaces), transdermal administration, and intraventricular injection (injection into a ventricle of the brain, e.g., by an implanted catheter or omman reservoir, such as in the case of morbid obesity) and although the most suitable route in any given case will depend on the nature and severity of the condition being treated and on the nature of the particular active compound which is being used.
Formulations suitable for oral administration may be presented in discrete units, such as capsules, cachets, lozenges, or tablets, each containing a predetermined amount of the active compound; as a powder or granules; as a solution or a suspension in an aqueous or non-aqueous liquid; or as an oil-in-water or water-in-oil emulsion. Such formulations may be prepared by any suitable method of pharmacy which includes the step of bringing into association the active compound and a suitable carrier (which may contain one or more accessory ingredients as noted above). In general, the formulations of the invention are prepared by uniformly and intimately admixing the active compound with a liquid or finely divided solid carrier, or both, and then, if necessary, shaping the resulting mixture. For example, a tablet may be prepared by compressing or molding a powder or granules containing the active compound, optionally with one or more accessory ingredients. Compressed tablets may be prepared by compressing, in a suitable machine, the compound in a free-flowing form, such as a powder or granules optionally mixed with a binder, lubricant, inert diluent, and/or surface active/dispersing agent(s). Molded tablets may be made by molding, in a suitable machine, the powdered compound moistened with an inert liquid binder.
Formulations suitable for buccal (sub-lingual) administration include lozenges comprising the active compound in a flavoured base, usually sucrose and acacia or tragacanth; and pastilles comprising the compound in an inert base such as gelatin and glycerin or sucrose and acacia.
Formulations of the present invention suitable for parenteral administration comprise sterile aqueous and non-aqueous injection solutions of the active compound, which preparations are preferably isotonic with the blood of the intended recipient. These preparations may contain anti-oxidants, buffers, bacteriostats and solutes which render the formulation isotonic with the blood of the intended recipient. Aqueous and non-aqueous sterile suspensions may include suspending agents and thickening agents. The formulations may be presented in unit\dose or multi-dose containers, for example sealed ampoules and vials, and may be stored in a freeze-dried (lyophilized) condition requiring only the addition of the sterile liquid carrier, for example, saline or water-for-injection immediately prior to use. Extemporaneous injection solutions and suspensions may be prepared from sterile powders, granules and tablets of the kind previously described. For example, in one aspect of the present invention, there is provided an injectable, stable, sterile composition comprising a compound of Formula (I), or a salt thereof, in a unit dosage form in a sealed container. The compound or salt is provided in the form of a lyophilizate which is capable of being reconstituted with a suitable pharmaceutically acceptable carrier to form a liquid composition suitable for injection thereof into a subject. The unit dosage form typically comprises from about 10 mg to about 10 grams of the compound or salt. When the compound or salt is substantially water-insoluble, a sufficient amount of emulsifying agent which is physiologically acceptable may be employed in sufficient quantity to emulsify the compound or salt in an aqueous carrier. One such useful emulsifying agent is phosphatidyl choline.
Formulations suitable for rectal administration are preferably presented as unit dose suppositories. These may be prepared by admixing the active compound with one or more conventional solid carriers, for example, cocoa butter, and then shaping the resulting mixture.
Formulations suitable for topical application to the skin preferably take the form of an ointment, cream, lotion, paste, gel, spray, aerosol, or oil. Carriers which may be used include petroleum jelly, lanoline, polyethylene glycols, alcohols, transdermal enhancers, and combinations of two or more thereof.
Formulations suitable for transdermal administration may be presented as discrete patches adapted to remain in intimate contact with the epidermis of the recipient for a prolonged period of time. Formulations suitable for transdermal administration may also be delivered by iontophoresis (see, for example, Pharmaceutical Research 3 (6):318 (1986)) and typically take the form of an optionally buffered aqueous solution of the active compound. Suitable formulations comprise citrate or bis\tris buffer (pH 6) or ethanol/water and contain from 0.1 to 0.2M active ingredient.
Further, the present invention provides liposomal formulations of the compounds disclosed herein and salts thereof. The technology for forming liposomal suspensions is well known in the art. When the compound or salt thereof is an aqueous-soluble salt, using conventional liposome technology, the same may be incorporated into lipid vesicles. In such an instance, due to the water solubility of the compound or salt, the compound or salt will be substantially entrained within the hydrophilic center or core of the liposomes. The lipid layer employed may be of any conventional composition and may either contain cholesterol or may be cholesterol-free. When the compound or salt of interest is water-insoluble, again employing conventional liposome formation technology, the salt may be substantially entrained within the hydrophobic lipid bilayer which forms the structure of the liposome. In either instance, the liposomes which are produced may be reduced in size, as through the use of standard sonication and homogenization techniques.
Of course, the liposomal formulations containing the compounds disclosed herein or salts thereof, may be lyophilized to produce a lyophilizate which may be reconstituted with a pharmaceutically acceptable carrier, such as water, to regenerate a liposomal suspension.
Other pharmaceutical compositions may be prepared from the water-insoluble compounds disclosed herein, or salts thereof, such as aqueous base emulsions. In such an instance, the composition will contain a sufficient amount of pharmaceutically acceptable emulsifying agent to emulsify the desired amount of the compound or salt thereof. Particularly useful emulsifying agents include phosphatidyl cholines, and lecithin.
In addition to compounds of formula (I) or their salts, the pharmaceutical compositions may contain other additives, such as pH-adjusting additives. In particular, useful pH-adjusting agents include acids, such as hydrochloric acid, bases or buffers, such as sodium lactate, sodium acetate, sodium phosphate, sodium citrate, sodium borate, or sodium gluconate. Further, the compositions may contain microbial preservatives. Useful microbial preservatives include methylparaben, propylparaben, and benzyl alcohol. The microbial preservative is typically employed when the formulation is placed in a vial designed for multidose use. Of course, as indicated, the pharmaceutical compositions of the present invention may be lyophilized using techniques well known in the art.
3. Dosage and Routes of Administration.
As noted above, the present invention provides pharmaceutical formulations comprising the active compounds (including the pharmaceutically acceptable salts thereof), in pharmaceutically acceptable carriers for oral, rectal, topical, buccal, parenteral, intramuscular, intradermal, or intravenous, and transdermal administration.
The therapeutically effective dosage of any specific compound, the use of which is in the scope of present invention, will vary somewhat from compound to compound, and patient to patient, and will depend upon the condition of the patient and the route of delivery. As a general proposition, a dosage from about 0.1 to about 50 mg/kg will have therapeutic efficacy, with all weights being calculated based upon the weight of the active compound, including the cases where a salt is employed. Toxicity concerns at the higher level may restrict intravenous dosages to a lower level such as up to about 10 mg/kg, with all weights being calculated based upon the weight of the active base, including the cases where a salt is employed. A dosage from about 10 mg/kg to about 50 mg/kg may be employed for oral administration. In some embodiments, a dosage from about 0.5 mg/kg to 5 mg/kg may be employed for intramuscular injection. In some embodiments, dosages are 1 μmol/kg to 50 mol/kg, and more preferably 22 μmol/kg and 33 mol/kg of the compound for intravenous or oral administration. The duration of the treatment can be once per day for a period of two to three weeks or until the condition is essentially controlled.
As noted above, the active compounds described herein are useful for the treatment of cancer. Example cancers that may be treated by the compounds and methods of the invention include, but are not limited to, myeloid leukemia, lymphoblastic leukemia, melanoma, breast, lung, colon, liver, gastric, kidney, ovarian, uterine, and brain cancer.
The present invention is explained in greater detail in the following non-limiting Examples.

To a suspension of 6-(methylthio)-1H-pyrazolo[3,4-d]pyrimidin-3(2H)-one (0.50 g, 2.7 mmol) in CH3CN (15 mL) was added a CH3CN solution of P(O)Br3 (1.57 g, 5.5 mmol) in a pressure vessel. The mixture was sonicated for 30 min before being heated to 100° C. for 16 h (overnight). After it was cooled to 0° C., H2O and aqueous ammonium hydroxide were added to basify the mixture. The mixture was stirred at 0° C. for 1 h. The aqueous layer was extracted with EtOAc (10×). The combined EtOAc layer was dried (Na2SO4), and concentrated to give 3-bromo-6-(methylthio)-1H-pyrazolo[3,4-d]pyrimidine (0.51 g, 77%) as a brown solid. 1H NMR (400 MHz, DMSO-d6) δ: 9.00 (s, 1H), 5.57 (s, 311); MS m/z 245.00 [M+H]+.
A 10 mL microwave tube was charged with 3-bromo-6-(methylthio)-1H-pyrazolo[3,4-d]pyrimidine (0.3 g, 1.22 mmol), K2CO3 (0.51 g, 3.66 mmol), and DMSO (2 mL). The mixture was stirred for 20 min before 4-(bromomethyl)cyclohexylcarbamate (0.45 g, 1.53 mmol) and THF (4 mL) was added. The resulting mixture was heated at 150° C. for 10 minutes in microwave. The reaction mixture was poured into water and extracted with Et2O (3×). The combined ether layer was dried (Na2SO4) and concentrated. The crude mixture was purified by Isco to provide tert-butyl 4-((3-bromo-6-(methylthio)-1H-pyrazolo[3,4-d]pyrimidin-1-yl)methyl)cyclohexylcarbamate (0.46 g, 83%) as a white solid. MS m/z 478.10 [M+Na]+.
To a solution of tert-butyl 4-((3-bromo-6-(methylthio)-1H-pyrazolo[3,4-d]pyrimidin-1-yl)methyl)cyclohexylcarbamate (0.91 g, 2.0 mmol) in CH2Cl2 (30 mL) was added meta-Chloroperoxybenzoic acid (1.34 g, 77%, 6 mmol) at room temperature. The color of the solution changed to light purple from colorless. After 2 h, the reaction was diluted with EtOAc. The organic solution was then washed with 1 N NaOH (3×), dried (NaSO4), and concentrated. The resulting residue was dissolved in THF (10 mL) before a 2.0 M methylamine solution in THF (10 mL, 20 mmol) was added at room temperature. The resulting solution was heated at 60° C. for 2 h. After removal of the solvent, it was purified by Isco to provide tert-butyl 4-((3-bromo-6-(methylamino)-1H-pyrazolo[3,4-d]pyrimidin-1-yl)methyl)cyclohexylcarbamate (0.75 g, 85%) as a white solid. MS m/z 439.2 [M+H]+.
A 30 mL microwave tube was charged with tert-butyl 4-((3-bromo-6-(methylamino)-1H-pyrazolo[3,4-d]pyrimidin-1-yl)methyl)cyclohexylcarbamate (0.070 g, 0.16 mmol), p-tolylboronic acid (0.065 g, 0.48 mmol), potassium phosphonate (0.10 g, 0.48 mmol), tetrakis(triphenylphosphine)palladium (0.018 g, 0.016 mmol), dioxane (2 mL) and water (0.5 mL). After stirring for 5 min, the reaction was heat at 150° C. for 10 min in microwave. The reaction was diluted with EtOAc and washed with water. The aqueous layer was extracted with EtOAc (3×). The combined organic layers were dried (Na2SO4), concentrated, and purified by Isco to provide tert-butyl 4-((6-(methylamino)-3-p-tolyl-1H-pyrazolo[3,4-d]pyrimidin-1-yl)methyl)cyclohexylcarbamate (0.064 g, 89%) as a white solid.
To a solution of tert-butyl 4-((6-(methylamino)-3-p-tolyl-1H-pyrazolo[3,4-d]pyrimidin-1-yl)methyl)cyclohexylcarbamate (0.064 g, 0.14 mmol) in CH2Cl2 (2 mL) was added trifluoroacetic acid (0.6 mL) at ambient temperature. After stirring for 2 h, the solvent was evaporated. The residue was purified by preparative HPLC to provide 1-((4-aminocyclohexyl)methyl)-N-methyl-3-p-tolyl-H-pyrazolo[3,4-d]pyrimidin-6-amine (UNC00000478A) as a yellow solid (TFA salt) (0.063 g, 95%). MS m/z 351.3 [M+H]+.

General Procedure E:
To a solution of 3-bromo-N-butyl-1H-pyrazolo[3,4-d]pyrimidin-6-amine (122 mg, 0.45 mmol) and 4-hydroxy-cyclohexyl chloride (260 mg, 1.9 mmol) in DMF (6.0 mL) was added K2CO3 (270 g, 2.0 mmol). The mixture was heated at 150° C. for overnight. After the reaction was cooled to room temperature, the reaction was quenched with H2O. The reaction mixture was partitioned in H2O and EtOAc. The aqueous phase was extracted with EtOAc (3×). The combined organic phase were dried (Na2SO4) and concentrated. The residue was purified by Isco to provide a mixture of cis- and trans-1-(4-hydroxy-cyclohexyl)-3-bromo-N-butyl-1H-pyrazolo[3,4-d]pyrimidin-6-amine (90 mg, 54%) as a yellow solid.
A 10 mL microwave tube was charged with 1-(4-hydroxy-cyclohexyl)-3-bromo-N-butyl-1H-pyrazolo[3,4-d]pyrimidin-6-amine (0.070 g, 0.19 mmol), (4-piperidinsulfonyl) phenyl boronic acid (0.10 g, 0.40 mmol), potassium carbonate (0.086 g, 0.62 mmol), tetrakis(triphenylphosphine)palladium (0.025 g, 0.022 mmol), DMF (2.0 mL) and water (0.50 mL). After stirring for 5 min, the reaction was heat at 150° C. for 10 min in microwave. The reaction was diluted with EtOAc and washed with water. The aqueous layer was extracted with EtOAc (3×). The combined organic layers were dried (Na2SO4), concentrated, and purified by Isco and HPLC to provide cis-1-(4-hydroxy-cyclohexyl)-3-(4-piperidinsulfonyl-phenyl)-1H-pyrazolo[3,4-d]pyrimidin)-6-amine (UNC1065A) (0.011 g, 12%) as a white solid, 1H NMR (400 MHz, CD3OD). δ 9.21 (s, 1H), 8.22 (d, J=8.4 Hz, 2H), 7.98 (d, J=8.4 Hz, 2H), 4.79-4.69 (m, 1H), 4.08-4.02 (m, 1H), 3.55 (t, J=7.1 Hz, 2H), 3.32-3.25 (m, 4H), 2.62-2.46 (m, 2H), 2.07-1.96 (m, 2H), 1.89-1.65 (m, 10H), 1.48 (qd, J=14.5, 7.3 Hz, 2H), 1.01 (t, J=7.4 Hz, 3H); MS m/z 499.0 [M+1]+, and trans-1-(4-hydroxy-cyclohexyl)-3-(4-piperidinsulfonyl-phenyl)-1H-pyrazolo[3,4-d]pyrimidin-6-amine (UNC1064A) (0.009 g, 10%) as a white solid. 1H NMR (400 MHz, CD3OD). δ 9.20 (s, 1H), 8.20 (d, J=8.5 Hz, 2H), 7.98 (d, J=8.5 Hz, 2H), 4.75-4.64 (m, 1H), 3.78-3.67 (m, 1H), 3.55 (t, J=7.1 Hz, 2H), 3.32-3.23 (m, 4H), 2.30-2.02 (m, 6H), 1.85-1.64 (m, 6H), 1.62-1.42 (m, 4H), 1.02 (t, J=7.4 Hz, 3H); MS m/z 499.0 [M+1]+.
