[0124] Suitable diluents for forming a table or capsule composition containing the compounds include, but are not limited to, lactose (as, for example, the monohydrate, spray-dried monohydrate or anhydrous form), chitosan polymers and chitosan derivatives (e.g. N-trimethylene chloride chitosan, chitosan esters, chitosan modified with hydrophilic groups, such as amino groups, carboxyl groups, sulfate groups, etc.), N-sulfonated derivatives of chitosan, quatemarized derivatives of chitosan, carbosyalkylated chitosan, microcrystalline chitosan, mannitol, xylitol, dextrose, sucrose, sorbitol, microcrystalline cellulose, starch and dibasic calcium phosphate dihydrate. Tablet or capsule composition containing the compounds may also contain surface active agents, such as sodium lauryl sulfate and polysorbate 80, and glidants such as silicon dioxide and talc, in the coating. When present, surface active agents can have a concentration in a range from about 0.2 wt% to 5 wt% of the tablet or capsule formulation.

[0125] Tablet or capsule compositions containing the compounds also generally contain lubricants, such as magnesium stearate, calcium stearate, zinc stearate, sodium stearyl fumarate, and mixtures of magnesium stearate with sodium lauryl sulphate. Lubricants can have a concentration in a range from about 0.25 wt% to 10 wt%, from about 0.5 wt% to about 3 wt% of the tablet or capsule composition.

[0126] Other possible excipients included in a tablet or capsule formulation containing the compounds include glidants (e.g. Talc or colloidal anhydrous silica at about 0.1 wt% to about 3 wt% of the table or capsule formulation), antioxidants, colourants, flavouring agents, preservatives and taste-masking agents. When present, glidants can have a concentration in a range from about 0.2 wt% to 1 wt% of the tablet or capsule composition.

[0127] An exemplary tablet composition contains up to about 80 wt% of the compounds described herein, from about 10 wt% to about 90 wt% binder, from about 0 wt% to about 85 wt% diluent, from about 2 wt% to about 10 wt% disintegrant, and from about 0.25 wt% to about 10 wt % lubricant.

[0128] Tablet or capsule blends, including the compounds and one or more suitable excipients, may be compressed directly or by roller to form tablets. Tablet or capsule blends or portions of the blends may alternatively be wet-, dry-, or melt-granulated, melt congealed, or extruded before tableting. The final table or capsule composition may contain one or more layers and may be coated or uncoated; it may even be encapsulated in a particle, such as a polymeric particle or a liposomal particle.

[0129] Solid formulations containing the compounds for oral administration may be formulated to be immediate and / or modified release. Modified release formulations include delayed, sustained, pulsed, controlled, targeted and programmed release formulations. b. Mucosal Formulation

[0130] The disclosed compounds can be formulated for pulmonary or mucosal administration. The administration can include delivery of the composition to the lungs, nasal, oral (sublingual, buccal), vaginal, or rectal mucosa.

[0131] For example, the compounds can also be administered intranasally or by oral inhalation, typically in the form of a dry powder (either alone, as a mixture, for example, in a dry blend with lactose, or as a mixed component particle, for example, mixed with phospholipids, such as phosphatidylcholine) from a dry powder inhaler or as an aerosol spray from a pressurised container, pump, spray, atomiser (optionally an atomiser using electrohydrodynamics to produce a fine mist), or nebuliser, with or without the use of a suitable propellant, such as water, ethanol -water mixture, 1,1,1,2-tetrafluoroethane or 1,1,1,2,3,3,3-heptafluoropropane. For intranasal or oral inhalation use, the powder may contain a bioadhesive agent, for example, chitosan or cyclodextrin. The term “aerosol” as used herein refers to any preparation of a fine mist of particles, which can be in solution or a suspension, whether or not it is produced using a propellant. Aerosols can be produced using standard techniques, such as ultrasonication or high-pressure treatment.

[0132] The pressurized container, pump, spray, atomizer, or nebulizer contains a solution or suspension of one or more of the compounds including, for example, ethanol, aqueous ethanol, or a suitable alternative agent for dispersing, solubilising, or extending release of the active, a propellant(s) as solvent and an optional surfactant, such as sorbitan trioleate, oleic acid, or an oligolactic acid.

[0133] Capsules (made, for example, from gelatin or hydroxypropylmethylcellulose), blisters and cartridges for use in an inhaler or insufflator may be formulated to contain a powder mix of the compounds described herein, a suitable powder base such as lactose or starch and a performance modifier such as 1 -leucine, mannitol, or magnesium stearate. The lactose may be anhydrous or in the form of a monohydrate, preferably the latter. Other suitable excipients include dextran, glucose, maltose, sorbitol, xylitol, fructose, sucrose, and trehalose.

[0134] A suitable solution formulation for use in an atomizer using electrohydrodynamics to produce a fine mist may contain from 1 pg to 20 mg of one or more of the compounds per actuation and the actuation volume may vary from 1 pl to 100 pl. A typical formulation may contain a plurality of the compounds disclosed herein, propylene glycol, sterile water, ethanol and sodium chloride. Alternative solvents that may be used instead of propylene glycol include glycerol and polyethylene glycol.

[0135] Suitable flavors, such as menthol and levomenthol, or sweeteners, such as saccharin or saccharin sodium, may be added to those formulations intended for inhaled / intranasal administration.

[0136] Formulations for inhaled / intranasal administration may be formulated to be immediate and / or modified release using for example, PGLA. Modified release formulations include delayed, sustained, pulsed, controlled, targeted, and programmed release formulations.

[0137] In the case of dry powder inhalers and aerosols, the dosage unit is determined by means of a valve which delivers a metered amount. Units in accordance with the compounds are typically arranged to administer a metered dose or "puff". The overall daily dose will be administered in a single dose or, more usually, as divided doses throughout the day.

[0138] In some forms, the compounds can be formulated for pulmonary delivery, such as intranasal administration or oral inhalation. Carriers for pulmonary formulations can be divided into those for dry powder formulations and for administration as solutions. Aerosols for the delivery of therapeutic agents to the respiratory tract are known in the art. For administration via the upper respiratory tract, the compounds can be formulated into an aqueous solution, e.g., water or isotonic saline, buffered or un-buffered, or as an aqueous suspension, for intranasal administration as drops or as a spray. Such aqueous solutions or suspensions may be isotonic relative to nasal secretions and of about the same pH, ranging e.g., from about pH 4.0 to about pH 7.4 or, from pH 6.0 to pH 7.0. Buffers should be physiologically compatible and include, simply by way of example, phosphate buffers. One skilled in the art can readily determine a suitable saline content and pH for an innocuous aqueous solution for nasal and / or upper respiratory administration.

[0139] In some forms, the aqueous solution is water, physiologically acceptable aqueous solutions containing salts and / or buffers, such as phosphate buffered saline (PBS), or any other aqueous solution acceptable for administration to an animal or human. Such solutions are well known to a person skilled in the art and include, but are not limited to, distilled water, de-ionized water, pure or ultrapure water, saline, phosphate-buffered saline (PBS). Other suitable aqueous vehicles include, but are not limited to, Ringer’s solution and isotonic sodium chloride. Aqueous suspensions may include suspending agents such as cellulose derivatives, sodium alginate, polyvinyl-pyrrolidone and gum tragacanth, and a wetting agent such as lecithin. Suitable preservatives for aqueous suspensions include ethyl and n-propyl p-hydroxybenzoate.

[0140] In some forms, solvents that are low toxicity organic (i.e. nonaqueous) class 3 residual solvents, such as ethanol, acetone, ethyl acetate, tetrahydrofuran, ethyl ether, and propanol may be used for the formulations. The solvent is selected based on its ability to readily aerosolize the formulation. The solvent should not detrimentally react with the compounds. An appropriate solvent should be used that forms a suspension of the compounds. The solvent should be sufficiently volatile to allow formation of an aerosol of the solution or suspension. Additional solvents or aerosolizing agents, such as freons, can be added as desired to increase the volatility of the solution or suspension.

[0141] In some forms, the pharmaceutical formulations may contain minor amounts of surfactants or other excipients well known to those of the art. In this context, “minor amounts” means no excipients are present that might affect or mediate penetration of the compounds in tissues and that the excipients that are present in amount that do not adversely affect penetration of the compounds in tissues.

[0142] In some forms, the pharmaceutical formulations containing one or more of the compounds can be administered directly to the mucous membranes (including the surface membranes of the nose, lungs and mouth), such that compounds cross the mucosal layer and enters the underlying tissues.

[0143] Such formulations for direct application on the mucous membrane generally contain a dermatologically acceptable carrier that is suitable for application to the mucous membrane, has good aesthetic properties, is compatible with the active agents and any other components, and will not cause any untoward safety or toxicity concerns.

[0144] The carrier can be in a wide variety of forms. For example, emulsion carriers, including, but not limited to, oil-in-water, water-in-oil, water-in-oil-in-water, and oil-in-water-in-silicone emulsions, are useful herein. These emulsions can cover a broad range of viscosities, e.g., from about 100 cps to about 200,000 cps. These emulsions can also be delivered in the form of sprays using either mechanical pump containers or pressurized aerosol containers using conventional propellants. These carriers can also be delivered in the form of a mousse or a transdermal patch. Other suitable topical carriers include anhydrous liquid solvents such as oils, alcohols, and silicones (e.g., mineral oil, ethanol isopropanol, dimethicone, cyclomethicone, and the like); aqueous-based single phase liquid solvents (e.g., hydro- alcoholic solvent systems, such as a mixture of ethanol and / or isopropanol and water); and thickened versions of these anhydrous and aqueous-based single phase solvents (e.g. where the viscosity of the solvent has been increased to form a solid or semi-solid by the addition of appropriate gums, resins, waxes, polymers, salts, and the like). Examples of topical carrier systems useful in the present formulations are described in the following four references all of which are incorporated herein by reference in their entirety: “Sun Products Formulary” Cosmetics & Toiletries, vol. 105, pp. 122-139 (December 1990); “Sun Products Formulary,” Cosmetics & Toiletries, vol. 102, pp. 117-136 (March 1987); U.S. Pat. No. 5,605,894 to Blank et al., and U.S. Pat. No. 5,681,852 to Bissett.

[0145] Formulations for direct application on the mucous membrane may be formulated to be immediate and / or modified release. Modified release formulations include delayed, sustained, pulsed, controlled, targeted and programmed release formulations. Thus, the compounds may be formulated as a solid, semi-solid, or thixotropic liquid for administration as an implanted depot providing modified release of the active agents. Examples of such formulations include drug-coated stents. c. Parenteral Formulations

[0146] Optionally, the pharmaceutical composition containing one or more of the disclosed compounds is in a form suitable for administration directly into the blood stream, into muscle, or into an internal organ. Suitable routes for such parenteral administration include intravenous, intraarterial, intraperitoneal, intrathecal, epidural, intracerebroventricular, intraurethral, intrasternal, intracranial, intramuscular, and subcutaneous delivery. Suitable means for parenteral administration include needle (including microneedle) injectors, needle-free injectors, and infusion techniques.

[0147] For example, the pharmaceutical formulation containing one or more of the compounds is in a form suitable for intramuscular administration, intravenous administration, intraperitoneal administration, or subcutaneous administration, or a combination thereof.

[0148] Parenteral formulations containing the compounds described herein are typically aqueous solutions which can contain excipients such as salts, carbohydrates and buffering agents (e.g., from about pH 6.5 to about pH 8.0, from about pH 6.5 to about pH 7.4, from about pH 6.5 to about pH 7.0, from about pH 7.0 to pH 8.0, or from about pH 7.0 to about pH 7.4), but, for some applications, they may be more suitably formulated as a sterile aqueous solution or as a dried form to be used in conjunction with a suitable vehicle such as sterile, pyrogen-free water.

[0149] The liquid compositions containing the compounds for parenteral administration may be a solution, a suspension, or an emulsion.

[0150] The liquid pharmaceutically acceptable carrier forming the parenteral composition containing the compounds can include one or more physiologically compatible buffers, such as a phosphate buffers. One skilled in the art can readily determine a suitable saline content and pH for an aqueous carrier for administration (e.g., from about pH 6.5 to about pH 8.0, from about pH 6.5 to about pH 7.4, from about pH 6.5 to about pH 7.0, from about pH 7.0 to pH 8.0, or from about pH 7.0 to about pH 7.4).

[0151] Liquid compositions containing the compounds for parenteral administration may include one or more suspending agents, such as cellulose derivatives, sodium alginate, polyvinylpyrrolidone, gum tragacanth, or lecithin. The liquid compositions may also include one or more preservatives, such as ethyl or n-propyl p-hydroxybenzoate.

[0152] Optionally, the liquid composition containing the compounds contains one or more solvents that are low toxicity organic (i.e., nonaqueous) class 3 residual solvents, such as ethanol, acetone, ethyl acetate, tetrahydofuran, ethyl ether, and propanol, and a combination thereof. Any such solvents included in the liquid formulation should not detrimentally react with the compounds or any additional active agents in the liquid composition. Solvents such as freon, alcohol, glycol, polyglycol, or fatty acid, can also be included in the liquid composition containing the compounds as desired to increase the volatility of the solution or suspension.

[0153] Liquid compositions containing the compounds for parenteral administration may also contain minor amounts of polymers, surfactants, or other pharmaceutically acceptable excipients known to those in the art. In this context, "minor amounts" means an amount that is sufficiently small to avoid adversely affecting uptake of the compounds by the targeted cells, such as pituitary gonadotrophs.

[0154] The preparation of parenteral compositions containing the compounds is typically under sterile conditions, for example, by lyophilisation, which can be accomplished using standard pharmaceutical techniques known to those skilled in the art.

[0155] Compositions for parenteral administration containing the compounds may be formulated to provide immediate and / or modified release of the active agent. Modified release formulations include delayed, sustained, pulsed, controlled, targeted and programmed release formulations. d. Topical Formulations

[0156] The compounds can be administered directly to the external surface of the skin or the mucous membranes (including the surface membranes of the nose, lungs and mouth), such that the compounds can cross the external surface of the skin or mucous membrane and enters the underlying tissues.

[0157] Formulations for topical administration generally contain a dermatologically acceptable carrier that is suitable for application to the skin, has good aesthetic properties, is compatible with the active agents and any other components, and will not cause any untoward safety or toxicity concerns.

[0158] The carrier can be in a wide variety of forms. For example, emulsion carriers, including, but not limited to, oil-in-water, water-in-oil, water-in-oil-in-water, and oil-in-water-in-silicone emulsions, are useful herein. These emulsions can cover a broad range of viscosities, e.g., from about 100 cps to about 200,000 cps. These emulsions can also be delivered in the form of sprays using either mechanical pump containers or pressurized aerosol containers using conventional propellants. These carriers can also be delivered in the form of a mousse or a transdermal patch. Other suitable topical carriers include anhydrous liquid solvents such as oils, alcohols, and silicones (e.g., mineral oil, ethanol isopropanol, dimethicone, cyclomethicone, and the like); aqueous-based single phase liquid solvents (e.g., hydro- alcoholic solvent systems, such as a mixture of ethanol and / or isopropanol and water); and thickened versions of these anhydrous and aqueous-based single phase solvents (e.g. where the viscosity of the solvent has been increased to form a solid or semi-solid by the addition of appropriate gums, resins, waxes, polymers, salts, and the like). Examples of topical carrier systems useful in the present formulations are described in the following four references all of which are incorporated herein by reference in their entirety: “Sun Products Formulary” Cosmetics & Toiletries, vol. 105, pp. 122-139 (December 1990); “Sun Products Formulary,” Cosmetics & Toiletries, vol. 102, pp. 117-136 (March 1987); U.S. Pat. No. 5,605,894 to Blank et al., and U.S. Pat. No. 5,681,852 to Bissett.

[0159] Formulations containing the compounds for topical administration may be formulated to be immediate and / or modified release. Modified release formulations include delayed, sustained, pulsed, controlled, targeted and programmed release formulations. Thus, the compounds may be formulated as a solid, semi-solid, or thixotropic liquid for administration as an implanted depot providing modified release of the compounds. Examples of such formulations include drug-coated stents and poly(dl-lactic-coglycolic)acid (PGLA) microspheres. e. Amount of Curcumin-Based Compounds

[0160] Pharmaceutical compositions typically contain an effective amount of the compound(s) and one or more pharmaceutically acceptable carriers and / or excipients. As used herein, the term “effective amount” means any amount of the compounds that is sufficient to achieve the desired therapeutic, prophylactic, and / or diagnostic effect on a biological sample or in a subject to which it is administered. Depending on the specific condition to be treated and / or the route of administration, such an effective amount of the compounds can be from about 0.01 mg / kg to about 250 mg / kg body weight, from about 0.1 mg / kg to about 250 mg / kg body weight, from about 0.01 mg / kg to about 200 mg / kg body weight, from about 0. 1 mg / kg to about 200 mg / kg body weight, from about 0.01 mg / kg to about 150 mg / kg body weight, from about 0.1 mg / kg to about 150 mg / kg body weight, from about 0.01 mg / kg to about 100 mg / kg body weight, from about 0.1 mg / kg to about 100 mg / kg body weight, from about 0.01 mg / kg to about 50 mg / kg body weight, from about 0. 1 mg / kg to about 50 mg / kg body weight, from about 0.01 mg / kg to about 10 mg / kg body weight, from about 0.1 mg / kg to about 10 mg / kg body weight, from about 0.2 mg / kg to about 20 mg / kg body weight, or from about 0.5 mg / kg to about 50 mg / kg body weight, of the subject per day, which can be administered as a single daily dose, divided over one or more daily doses.

[0161] For example, the effective amount of the compounds is about 0.1 mg / kg, about 0.5 mg / kg, about 1 mg / kg, about 10 mg / kg, about 20 mg / kg, about 30 mg / kg, about 40 mg / kg, about 50 mg / kg, about 60 mg / kg, about 70 mg / kg, about 80 mg / kg, about 90 mg / kg, about 100 mg / kg, about 110 mg / kg, about 120 mg / kg, about 130 mg / kg, about 140 mg / kg, about 150 mg / kg, about 160 mg / kg, about 170 mg / kg, about 180 mg / kg, about 190 mg / kg, about 200 mg / kg, about 210 mg / kg, about 220 mg / kg, about 230 mg / kg, about 240 mg / kg, or about 250 mg / kg, of the subject per day, which can be administered as a single daily dose, divided over one or more daily doses. The amount of the compounds administered, the route of administration, and the further treatment regimen can be determined by the treating clinician or testing technologies, depending on factors such as the age, gender and general condition of the subject, the nature and severity of the disease / symptoms being prevented, treated, or diagnosed, and / or the samples being tested.

[0162] In some forms, the pharmaceutical composition is in a unit dosage form, and can be suitably packaged, for example in a box, blister, vial, bottle, sachet, ampoule or in any other suitable singledose or multi-dose holder or container (which can be properly labeled); optionally with one or more leaflets containing product information and / or instructions for use. Generally, such unit dosages can contain from 0.01 to 1000 mg, such as from 0.01 to 500 mg, from 0.01 to 100 mg, from 0.01 to 50 mg, from 0.01 to 10 mg, from 0.01 to 1 mg, from 0.1 to 500 mg, from 0.1 to 100 mg, from 0.1 to 50 mg, from 0.1 to 10 mg, or from 0.1 to 1 mg, of the disclosed compounds, e.g., about 0.1, 0.2, 0.5, 1, 5, 10, 25, 50, 100, 200, 300 or 400 mg per unit dosage. f. Additional Active Agent

[0163] In some forms, the pharmaceutical composition containing the compounds also contains one or more additional active agent(s), such as one or more additional anticancer agent(s) and / or antiinflammatory agents. For example, one or more additional active agents is formulated into the same pharmaceutical composition containing one or more of the compounds described herein as a single dosage unit or as multiple dosage units for coordinated, combination, or concomitant administration, or into separate pharmaceutical compositions for combinational therapy.

[0164] Alternatively, the one or more additional active agents may be formulated as separate pharmaceutical compositions, for example, as a single dosage unit or as multiple dosage units, for co-administration with the pharmaceutical composition containing one or more of the compounds described herein. When formulated into a pharmaceutical composition that is separated from the pharmaceutical composition containing the disclosed compounds, the one or more additional active agents may be formulated in various formulations, for example, injectable formulations, lyophilized formulations, liquid formulations, or oral formulations. The formulation can be selected based upon the suitable administration route.

Additional anti-inflammatory agents that can be included in the pharmaceutical compositions or formulations are described, for example, on WebMD, “Anti-inflammatory Drugs,” web site webmd.com / arthritis / anti- inflammatory -drugs; Barnes, Nature, 402(6760): 31-38 (1999); and Rainsford, Inflammation in the pathogenesis of chronic diseases 3:27 (2007).

[0167] III. Methods of Use

[0168] The disclosed compounds are suitable for use in treating cancer and / or anti-inflammatory disease / disorder. In some forms, the compounds are particularly useful in cancer therapy. In some forms, the cancer being treated using the disclosed method is a solid cancer, such as breast cancer and / or colon cancer.

[0169] “Treatment” or “treating” refers to the medical management of a patient with the intent to cure, ameliorate, stabilize, or prevent a disease, pathological condition, or disorder, such as a cancer. This term includes active treatment, that is, treatment directed specifically toward the improvement of a disease, pathological condition, or disorder, such as a cancer; and also includes causal treatment, that is, treatment directed toward removal of the cause of the associated disease, pathological condition, or disorder, such as a cancer. In addition, this term includes palliative treatment, that is, treatment designed for the relief of symptoms rather than the curing of the disease, pathological condition, or disorder, such as a cancer; preventative treatment, that is, treatment directed to minimizing or partially or completely inhibiting the development of the associated disease, pathological condition, or disorder, such as a cancer; and supportive treatment, that is, treatment employed to supplement another specific therapy directed toward the improvement of the associated disease, pathological condition, or disorder, such as a cancer.

[0170] Generally, the method for treating cancer includes a step of administering the compounds or pharmaceutical composition thereof to a subject in need thereof.

[0171] The administration in step (i) can be performed using any suitable technique, such as oral administration, intranasal administration, intramuscular administration, intravenous administration, intraperitoneal administration, subcutaneous administration, or topical administration, or a combination thereof.

[0172] Step (i) (administration of the pharmaceutical composition) of the disclosed method may occur one or more times. When more than one administration step is performed, each administration can be performed regularly every 5 mins, every 10 mins, every 20 mins, every 30 mins, every hour, every 2 hours, every day, every two days, every 3 days, every week, every two weeks, every month, etc.; or irregularly with a time interval of 5 mins, 10 mins, 20 mins, 30 mins, 1 hour, 2 hours, 1 day, 2 days, 3 days, 5 days, 1 week, 2 weeks, etc. The specific number of treatment and time interval for the treatment can be determined by the treating clinician or testing technologies, depending on factors such as the age, gender and general condition of the subject, the nature and severity of the disease / symptoms being prevented, treated, or diagnosed, and / or the samples being tested.

[0173] In some forms, following the administration step or all of the administration steps, an effective amount of the compounds in the pharmaceutical formulation is administered to the subject to ameliorate one or more symptoms associated with the cancer in the subject. In some forms, the treatment effect is achieved by the anticancer property of the compounds, such as by killing cancer cells and / or reducing or preventing growth or proliferation of the cancer cells. In some forms, the treatment effect is achieved by the anti-inflammatory property of the compounds, such as by inhibiting one or more inflammation markers, e.g., COX-1, COX-2, TNF-a, NO, and / or IL-6. In some forms, the treatment effect is achieved by both the anticancer property and the antiinflammatory property of the compounds. In some forms, the disclosed compounds are more effective in treating the cancer compared to a corresponding curcumin mimic alone and / or a corresponding anti-inflammatory drug alone.

[0174] For example, following the administration step or all of the administration steps (if the administration occurs more than one time), an effective amount of the compounds is administered to the subject, such that the tumor weight (such as a breast cancer or a colon cancer) and / or tumor volume in the subject is at least 10%, at least 20%, at least 30%, at least 40%, or at least 50% less than a control that is administered with the pharmaceutical formulation but contains the corresponding curcumin mimic alone.

[0175] For example, following the administration step or all of the administration steps (if the administration occurs more than one time), an effective amount of the compounds is administered to the subject, such that one or more symptoms associated with a cancer-related inflammation in the subject is at least 10%, at least 20%, at least 30%, at least 40%, or at least 50% less severe than a control that is administered with the pharmaceutical formulation but contains the corresponding anti-inflammatory drug alone.

[0176] In some forms, following the administration step or all of the administration steps, the effective amount of the compounds administered to the subject is from about 0.1 pg to about 1000 pg, from about 0.1 pg to about 500 pg, from about 0.1 pg to about 100 pg, from about 0.5 pg to about 50 pg, from about 1 pg to about 1000 pg, from about 1 pg to about 500 pg, from about 1 pg to about 100 pg, from about 1 pg to about 50 pg, from about 1 pg to about 25 pg, from about 1 pg to about 10 pg, from about 2 pg to about 20 pg, or from about 5 pg to about 50 pg, per g of the subject.

[0255] Results

[0256] Characterization ofN-( 2-( 3, 5-Bis( (E)-4-methylbenzylidene )-4-oxopiperidin-l -yl )-2-oxoethyl )- 2,2-dichloroacetamide ( DHld)

[0257] The structure of DHld was first confirmed with]H-NMR (Data not shown). There are 24 total protons, which is expected from the structure of the compound. The two alkene protons can be seen furthest downfield at 7.89 and 7.86 ppm. These peaks are shifted far downfield due to their position in being on the P-carbon of an a,P-unsaturated ketone. The amide N-H proton can be seen as a broad singlet at 7.51 ppm. The 8 aromatic protons can be seen in the 7.37 to 7.25 ppm range. The presence of the DCA proton can be seen as a singlet at 5.89 ppm. The two sets of piperidone alkane protons can be seen as two singlets at 4.95 and 4.68 ppm. The protons present from the amino acid glycine can be seen as a doublet at 3.98 ppm. Lastly, the presence of the methyl substituents can be seen as two singlets at 2.43 and 2.40 ppm. A13C-NMR spectra was then taken to confirm the identity and location of carbons in compound DHld (Data not shown). The spectra contained 20 unique carbons, which is in agreement with the expected number as the two carbons ortho to the methyl group and the two carbons meta to the methyl are equivalent carbons on their respective rings. The carbon for the ketone in the piperidone ring can be seen at 186.0 ppm. The two amide carbonyl carbons can be seen at 166.0 and 164.1 ppm. The DCA carbon attached to the chlorines can be seen at 66.2 ppm. The two carbons corresponding to the two alkane carbons in the piperidone ring can be seen at 45.7 and 44.1 ppm. The amino acid alkane carbon can be seen at 41.7 ppm. Lastly, the methyl substituent carbons show up as an identical carbon at 21.7 ppm.

[0258] Physical characteristics began with IR spectroscopy (Data not shown). The N-H stretch can be seen at 3295 cm1. The presence of alkane carbons can be seen in the C-H stretch at 2990 cm1. The C=C stretch can be identified at 1702 cm1. The presence of the amide C=O can be seen at the peak at 1644 cm1. The ketone stretch for the a, P-unsaturated ketone C=O stretch is seen at 1605 cm1. The C-N stretch can be seen at 1172 cm1. Lastly, the stretch corresponding to the C-Cl bond can be seen at 809 cm1. The compound was synthesized in an excellent yield of 87% and had a melting point range of 179-183 °C.

[0259] Characterization of N-(3-( 3, 5-Bis( ( E )-4-methoxybenzylidene )-4-oxopiperidin-l -yl )-3- oxopropyl)-2,2-dichloroacetamide (DH2e)

[0260] The spectra obtained of1H-NMR were similar to that of all the other spectra obtained, with again 26 protons similar to DH2d (Data not shown). The methoxy protons were visible as two singlets 3.89 and 3.86 ppm. The13C-NMR was again similar to that of the other spectra with 22 total carbon peaks present, containing an extra carbon due to the methoxy carbons showing up as non-equivalent similar to the glycine compound DHle, which can be seen at 55.6 and 55.5 ppm (Data not shown).

[0261] The IR spectra obtained contained all the functional groups present as seen in the other compounds’ spectra (Data not shown). The product was obtained in an excellent yield of 96% and had a melting point range of 168-170 °C. Characterization of N-( 4-(3, 5-Bis( ( E )-4-methylbenzylidene)-4-oxopiperidin-l -yl)-4- oxobutyl )-2,2-dichloroacetamide (DH3d)

[0262] The characterizations of DH3d began with1H-NMR in which 28 total protons were present due to the use of y- Aminobutyric acid for this compound (Data not shown). The proton signals were again in agreement with the other spectra, and the protons from the use of y- Aminobutyric acid can be seen as a quartet at 3.23 ppm being split by the two protons on the middle alkane chain carbon and the proton attached to the nitrogen. The next signal from the amino acid was seen as a triplet at 2.25 ppm, which was being split by the two protons on the middle alkane carbon. The final peak from the amino acid is for the middle alkane carbon and appeared as a quintet at 1.80 ppm, being split by the 4 total protons on the carbons adjacent to it. The13C-NMR spectra contained 22 total carbons as expected (Data not shown). The shifts were similar to those of all the spectra obtained, with the carbons from the amino acid being seen at 40.4, 30.6, and 23.5 ppm. Additionally, the methyl carbons were again equivalent and were at 21.7 ppm.

[0263] The IR spectra shared the same commonalities as the IR from all the other compounds (Data not shown). The compound was obtained in a yield of 47% and had a melting point range of 177- 179 °C.

[0264] Biological Data

[0265] From the synthesized compounds, a set of compounds prepared from the CUR-mimic scaffold, DCA, and glycine (DHla-e, NCMC1-5), were chosen for the initial biological investigation. The antitumor potential of NCMC1-5 drug candidates was tested in a human normal immortalized mammary epithelial cell line (MCF-10A), human ER+ BC cells (MCF-7), and TNBC cells (MDA-MB-231) using MTT proliferation assays, as discussed above. The results indicated that the candidates inhibited cell proliferation at sub micromolar concentrations in MCF-7 and MDA-MB-231 cells while they did not inhibit cell proliferation in MCF-10A cells (Figures 1A- 1C). MTT assay was carried out in MCF-10A (A), MCF-7 (B), and MDA-MB-231 (C) cells with NCMC1-5 at different concentrations (0, 0.01, 0.0316, 0.1, 0.316, 1, 3.16, 10, and 31.6 pM). Values are expressed as a mean ± SD of six replicates.

[0266] IC50 values were then obtained from the biological data for the compounds which can be seen in Table 1.

[0267] Table 1. IC50 values for DHla-e against two BC cell lines

[0268] As shown in the data, the activity of the compounds with the fluorine and methoxy substituents (DHlc & DHle) was greater than the other compounds tested. In the case of the methoxy group, it can be theorized that this is due to some hydrogen bond accepting interaction of the oxygen in the binding pocket, as the methoxy substituent is retained from the original structure of CUR. Fluorine can be beneficial as a substituent for multiple reasons, and is present in around 20% of all FDA approved pharmaceuticals. Firstly, fluorine is highly electronegative, which can lead to increased dipole interactions while also improving metabolic stability. Additionally, fluorine is relatively small, with a comparable radius to that of a hydrogen atom, and thus will not be likely to cause any steric hinderance with interactions in the binding pocket. Lastly, fluorine’s ability to act as a hydrogen bond acceptor could be contributing to its activity against the cell lines, similar to the hydrogen bond acceptor present in natural CUR.

[0269] Biological Studies of Compounds JI to J 17

[0270] Overall, the proposed products composed of ibuprofen, an amino acid linker, and a curcumin mimic (Figure 2) is a formidable approach to the formation of the new generation of NSAIDs. By linking these residues each with a benefit of its own, the end goal of producing a compound with higher selectivity (thus, lower side effects) and higher potency than chemotherapeutic drugs available in the market is within reach.
