Description

RELATED APPLICATIONS

[0001] This application claims priority to U.S. Provisional Patent Application No. 60/844,902 filed Sep. 15, 2006, the contents of which are incorporated by reference in their entirety.

BACKGROUND

[0002] Sunitinib is a potent multi-targeted kinase inhibitor that is efficacious in the treatment of cancers, most notably renal cell carcinoma and GI stroma tumor as approved by FDA. It is also undergoing clinical trials in a number of other cancers. Its structure is an indolinone derivative characterized by a basic diethylaminoethyl side chain. Although Sunitinib is very efficacious, its application is hampered by the side effects. The most common and severe toxicity in clinic is neutropenia and fatigue.

[0003]

[0004] This invention describes a novel class of Sunitinib derivatives with a cyclic side chain replacing the diethylaminiethyl side chain of Sunitinib. They are designed to overcome the fatigue problem of Sunitinib by improving its selectivity. Recently, a proteomic study of a Sunitinib analog, SU6668 found that SU6668 inhibits, among other proteins, AMPK (Godl et al, Cancer Res 2005, 65, 6919). Since AMPK is a key sensor of fuel and energy status in skeletal muscle (see review by Hardie and Sakamoto, Physiology 2006, 21, 48-60), it is hypothesized that inhibition of AMPK might be the cause of the clinically observed fatigue toxicity of Sunitinib. Thus, the cyclic derivatives of Sunitinib are designed to reduce the inhibitory activity of AMPK, thereby alleviating the fatigue problem of Sunitinib

When aqueous suspensions and/or emulsions are administered orally, the active ingredient may be suspended or dissolved in an oily phase is combined with emulsifying and/or suspending agents. If desired, certain sweetening and/or flavoring and/or coloring agents may be added.

[0298] The pharmaceutical compositions of this invention may also be administered in the form of suppositories for rectal administration. These compositions can be prepared by mixing a compound of this invention with a suitable non-irritating excipient which is solid at room temperature but liquid at the rectal temperature and therefore will melt in the rectum to release the active components. Such materials include, but are not limited to, cocoa butter, beeswax and polyethylene glycols.

[0299] Topical administration of the pharmaceutical compositions of this invention is useful when the desired treatment involves areas or organs readily accessible by topical application. For application topically to the skin, the pharmaceutical composition should be formulated with a suitable ointment containing the active components suspended or dissolved in a carrier. Carriers for topical administration of the compounds of this invention include, but are not limited to, mineral oil, liquid petroleum, white petroleum, propylene glycol, polyoxyethylene polyoxypropylene compound, emulsifying wax and water. Alternatively, the pharmaceutical composition can be formulated with a suitable lotion or cream containing the active compound suspended or dissolved in a carrier with suitable emulsifying agents. Suitable carriers include, but are not limited to, mineral oil, sorbitan monostearate, polysorbate 60, cetyl esters wax, cetearyl alcohol, 2-oetyldodecanol, benzyl alcohol and water. The pharmaceutical compositions of this invention may also be topically applied to the lower intestinal tract by rectal suppository formulation or in a suitable enema formulation. Topically-transdermal patches are also included in this invention.

[0300] The pharmaceutical compositions of this invention may be administered by nasal aerosol or inhalation. Such compositions are prepared according to techniques well-known in the art of pharmaceutical formulation and may be prepared as solutions in saline, employing benzyl alcohol or other suitable preservatives, absorption promoters to enhance bioavailability, fluorocarbons, and/or other solubilizing or dispersing agents known in the art.

[0301] A composition having the compound of the formulae herein and an additional agent (e.g., a therapeutic agent) can be administered using an implantable device. Implantable devices and related technology are known in the art and are useful as delivery systems where a continuous, or timed-release delivery of compounds or compositions delineated herein is desired. Additionally, the implantable device delivery system is useful for targeting specific points of compound or composition delivery (e.g., localized sites, organs). Negrin et al., Biomaterials, 22(6):563 (2001). Timed-release technology involving alternate delivery methods can also be used in this invention. For example, timed-release formulations based on polymer technologies, sustained-release techniques and encapsulation techniques (e.g., polymeric, liposomal) can also be used for delivery of the compounds and compositions delineated herein.

[0302] Also within the invention is a patch to deliver active chemotherapeutic combinations herein. A patch includes a material layer (e.g., polymeric, cloth, gauze, bandage) and the compound of the formulae herein as delineated herein. One side of the material layer can have a protective layer adhered to it to resist passage of the compounds or compositions. The patch can additionally include an adhesive to hold the patch in place on a subject. An adhesive is a composition, including those of either natural or synthetic origin, that when contacted with the skin of a subject, temporarily adheres to the skin. It can be water resistant. The adhesive can be placed on the patch to hold it in contact with the skin of the subject for an extended period of time. The adhesive can be made of a tackiness, or adhesive strength, such that it holds the device in place subject to incidental contact, however, upon an affirmative act (e.g., ripping, peeling, or other intentional removal) the adhesive gives way to the external pressure placed on the device or the adhesive itself, and allows for breaking of the adhesion contact. The adhesive can be pressure sensitive, that is, it can allow for positioning of the adhesive (and the device to be adhered to the skin) against the skin by the application of pressure (e.g., pushing, rubbing,) on the adhesive or device.

[0303] When the compositions of this invention comprise a combination of a compound of the formulae described herein and one or more additional therapeutic or prophylactic agents, both the compound and the additional agent should be present at dosage levels of between about 1 to 100%, and more preferably between about 5 to 95% of the dosage normally administered in a monotherapy regimen. The additional agents may be administered separately, as part of a multiple dose regimen, from the compounds of this invention. Alternatively, those agents may be part of a single dosage form, mixed together with the compounds of this invention in a single composition.

[0304] The recitation of a listing of chemical groups in any definition of a variable herein includes definitions of that variable as any single group or combination of listed groups. The recitation of an embodiment for a variable herein includes that embodiment as any single embodiment or in combination with any other embodiments or portions thereof.

[0305] The invention will be further described in the following examples. It should be understood that these examples are for illustrative purposes only and are not to be construed as limiting this invention in any manner.

EXAMPLES

[0306] The general procedure for the preparation of many examples is shown below:

[0307]

[0308] Step 1: A mixture of 5-fluoro-1,3-dihydroindol-2-one (A2) (20 g, 132 mmol), 5-formyl-2,4-dimethylpyrrole-3-carboxylic acid (A1) (21.1 g, 126 mmol), pyrrolidine (5 ml) and absolute ethanol (400 mL) were heated to reflux for 3 hours. Then the mixture was cooled to room temperature and the solid was collected by filtration, washed with ethanol (100 mL). The solid was stirred in ethanol (350 ml) at reflux for 0.5 h again. The mixture was cooled to room temperature and the solid was collected by filtration, washed with ethanol (100 mL) and dried under vacuum overnight to give (Z)-5-((5-fluoro-2-oxoindolin-3-ylidene)methyl)-2,4-dimethyl-1H-pyrrole-3-carboxylic acid (A3) (35.3 g, 93%) as orange solid. LC-MS observed [M−H]⁺: 299.2.

[0309] Step 2: (Z)-5-((5-fluoro-2-oxoindolin-3-ylidene)methyl)-2,4-dimethyl-1H-pyrrole-3-carboxylic acid (A3) (5 g, 16.7 mmol) was suspended in DMF (25 mL) with stirring for 5 min. DIEA (4.4 mL, 25 mmol) was then added and the mixture was stirred for 10 min. HART (6.32 g, 16.6 mmol) was added and the reaction mixture was stirred at room temperature for several hours. LC/MS was used to detect the completion of the reaction. Most DMF was evaporated under vacuum and the residue was suspended in ACN and stirred for another 30 min. The solid was collected via filtration and washed with ACN, dried under vacuum to provide (Z)-3H-[1,2,3]triazolo[4,5-b]pyridin-3-yl-5-((5-fluoro-2-oxoindolin-3-ylidene)methyl)-2,4-dimethyl-1H-pyrrole-3-carboxylate (A4) (5.36 g, 77%). LC-ESIMS observed [M−H]⁺: 417.3.

[0310] Step 3: To the solution of (Z)-3H-[1,2,3]triazolo[4,5-b]pyridin-3-yl 5-((5-fluoro-2-oxoindolin-3-ylidene)methyl)-2,4-dimethyl-1H-pyrrole-3-carboxylate (A4) (1.0 eq) in DMF solution was added the appropriate amine (1.2 eq) and DIEA (2.0 eq). The reaction mixture was stirred at room temperature for several hours. LC/MS detection was applied to determine completion of the reaction. After removal of most DMF under vacuum the mixture was precipitated with 5% diethylamine/methanol (25 mL) with stirring. The solid was collected by filtration and washed with methanol (5 mL) for several times, dried under high vacuum to provide the final compound (40-85% yields).
