FATTY ACID SYNTHASE INHIBITOR FOR USE IN THE TREATMENT OF DRUG RESISTANT CANCER

FIELD

The present disclosure relates generally to modulators of lipid synthesis, e.g., fatty acid synthase inhibitors, and methods of use thereof. The present modulators of lipid synthesis can be used for the treatment of paclitaxel-resistant cancers. The present modulators of lipid synthesis can also be used to increase the sensitivity of a cancer to treatment with paclitaxel or Nab-paclitaxel.

BACKGROUND

The dominant therapeutic approaches that are currently employed to treat cancer include surgical removal of primary tumors, tumor irradiation, and parenteral application of anti-mitotic cytotoxic agents. The continued dominance of long established therapies is mirrored by the lack of improvement in survival rates for most cancers. Surgical intervention often results in a release of tumor cells into the circulation or lymph systems from which metastatic tumors can subsequently be established.

Resistance of tumor cells to chemotherapeutic drugs is an important problem in the clinical management of cancer. Paclitaxel is an anti-mitotic cytotoxic agent that has provided improvement in patient outcomes. Unfortunately, despite this success, many patients will eventually progress to a phase of the disease that becomes resistant or unresponsive to treatment with paclitaxel and other traditional chemotherapeutic drugs.

The compounds useful in the present invention have been disclosed as inhibitors of fatty acid synthesis in U.S. Publication No. 2012/0264737, International PCT Publication No. WO 2015/105860, and International PCT Publication No. WO 2014/008197, which are incorporated herein by reference in their entirety. Surprisingly, the compounds of the present disclosure have been found to be useful to resensitize paclitaxel-resistant cancers to treatment with paclitaxel or Nab-paclitaxel.

In addition, each of the foregoing substituents may also be optionally substituted with one or more of the above substituents.

“Prodrug” is meant to indicate a compound that may be converted under physiological conditions or by solvolysis to a biologically active compound of the invention. Thus, the term “prodrug” refers to a metabolic precursor of a compound of the invention that is pharmaceutically acceptable. A prodrug may be inactive when administered to a subject in need thereof, but is converted in vivo to an active compound of the invention. Prodrugs are typically rapidly transformed in vivo to yield the parent compound of the invention, for example, by hydrolysis in blood. The prodrug compound often offers advantages of solubility, tissue compatibility or delayed release in a mammalian organism (see. Bundgard, H., Design of Prodrugs (1985), pp. 7-9, 21-24 (Elsevier, Amsterdam)). A discussion of prodrugs is provided in Higuchi, T., et al., A.C.S. Symposium Series, Vol. 14, and in Bioreversible Carriers in Drug Design, Ed. Edward B. Roche, American Pharmaceutical Association and Pergamon Press, 1987.

The term “prodrug” is also meant to include any covalently bonded carriers, which release the active compound of the invention in vivo when such prodrug is administered to a mammalian subject. Prodrugs of a compound of the invention may be prepared by modifying functional groups present in the compound of the invention in such a way that the modifications are cleaved, either in routine manipulation or in vivo, to the parent compound of the invention. Prodrugs include compounds of the invention wherein a hydroxy, amino or mercapto group is bonded to any group that, when the prodrug of the compound of the invention is administered to a mammalian subject, cleaves to form a free hydroxy, free amino or free mercapto group, respectively. Examples of prodrugs include, but are not limited to, acetate, formate and benzoate derivatives of alcohol or amide derivatives of amine functional groups in the compounds of the invention and the like.

The invention disclosed herein is also meant to encompass the in vivo metabolic products of the disclosed compounds. Such products may result from, for example, the oxidation, reduction, hydrolysis, amidation, esterification, and the like of the administered compound, primarily due to enzymatic processes. Accordingly, the invention includes compounds produced by a process comprising administering a compound of this invention to a subject for a period of time sufficient to yield a metabolic product thereof. Such products are typically identified by administering a radiolabelled compound of the invention in a detectable dose to an animal, such as rat, mouse, guinea pig, monkey, or to human, allowing sufficient time for metabolism to occur, and isolating its conversion products from the urine, blood or other biological samples.

“Stable compound” and “stable structure” are meant to indicate a compound that is sufficiently robust to survive isolation to a useful degree of purity from a reaction mixture, and formulation into an efficacious therapeutic agent.

“Subject” or “patient” includes mammals, which includes humans and both domestic animals such as laboratory animals and household pets (e.g., cats, dogs, swine, cattle, sheep, goats, horses, rabbits), and non-domestic animals such as wildlife and the like. Accordingly, the term “subject” or “patient” as used herein means any mammalian patient or subject to which the compounds of the invention can be administered. In an exemplary aspect of the present invention, to identify subject patients for treatment according to the methods of the invention, accepted screening methods are employed to determine risk factors associated with a targeted or suspected disease or condition or to determine the status of an existing disease or condition in a subject. These screening methods include, for example, conventional work-ups to determine risk factors that are associated with the targeted or suspected disease or condition. These and other routine methods allow the clinician to select patients in need of therapy using the methods and formulations of the present invention.

“Optional” or “optionally” means that the subsequently described event or circumstances may or may not occur, and that the description includes instances where said event or circumstance occurs and instances in which it does not. For example, “optionally substituted aryl” means that the aryl radical may or may not be substituted and that the description includes both substituted aryl radicals and aryl radicals having no substitution.

“Pharmaceutically acceptable carrier, diluent or excipient” includes without limitation any adjuvant, carrier, excipient, glidant, sweetening agent, diluent, preservative, dye/colorant, flavor enhancer, surfactant, wetting agent, dispersing agent, suspending agent, stabilizer, isotonic agent, solvent, or emulsifier which has been approved by the United States Food and Drug Administration as being acceptable for use in humans or domestic animals.

Often crystallizations produce a solvate of the compound of the invention. As used herein, the term “solvate” refers to an aggregate that comprises one or more molecules of a compound of the invention with one or more molecules of solvent. The solvent may be water, in which case the solvate may be a hydrate. Alternatively, the solvent may be an organic solvent. Thus, the compounds of the present invention may exist as a hydrate, including a monohydrate, dihydrate, hemihydrate, sesquihydrate, trihydrate, tetrahydrate and the like, as well as the corresponding solvated forms. The compound of the invention may be true solvates, while in other cases, the compound of the invention may merely retain adventitious water or be a mixture of water plus some adventitious solvent.

“Effective amount” or “therapeutically effective amount” refers to that amount of a compound of the invention which, when administered to a subject, preferably a human, is sufficient to treat a paclitaxel-resistant cancer, or to re-sensitize a paclitaxel-resistant cancer to treatment with paclitaxel or Nab-paclitaxel. The amount of a compound of the invention which constitutes a “therapeutically effective amount” will vary depending on the compound, the condition and its severity, the manner of administration, and the age or weight of the subject to be treated, but can be determined routinely by one of ordinary skill in the art having regard to his own knowledge and to this disclosure.

“Treating” or “treatment” as used herein covers the treatment of the disease or condition of interest in a subject, preferably a human, having the disease or condition of interest, and includes:

(i) preventing the disease or condition from occurring in a subject, in particular, when such subject is predisposed to the condition but has not yet been diagnosed as having it, or when a subject has had the disease and reoccurrence is possible or likely;

(ii) inhibiting the disease or condition, i.e., arresting its development;

(iii) relieving the disease or condition, i.e., causing regression of the disease or condition;

(iv) relieving the symptoms resulting from the disease or condition, i.e., relieving pain or side effects without addressing the underlying disease or condition. As used herein, the terms “disease” and “condition” may be used interchangeably or may be different in that the particular malady or condition may not have a known causative agent (so that etiology has not yet been worked out) and it is therefore not yet recognized as a disease but only as an undesirable condition or syndrome, wherein a more or less specific set of symptoms have been identified by clinicians; or

(v) resensitization of disease cells to treatment with a compound to which the disease is resistant or refractory.

The compounds of the invention, or their pharmaceutically acceptable salts may contain one or more asymmetric centers and may thus give rise to enantiomers, diastereomers, and other stereoisomeric forms that may be defined, in terms of absolute stereochemistry, as (R)- or (S)- or, as (D)- or (L)- for amino acids. The present invention is meant to include all such possible isomers, as well as their racemic and optically pure forms. Optically active (+) and (−), (R)- and (S)-, or (D)- and (L)-isomers may be prepared using chiral synthons or chiral reagents, or resolved using conventional techniques, for example, chromatography and fractional crystallization. Conventional techniques for the preparation/isolation of individual enantiomers include chiral synthesis from a suitable optically pure precursor or resolution of the racemate (or the racemate of a salt or derivative) using, for example, chiral high pressure liquid chromatography (HPLC).

Example 6
FASN Inhibition in Combination with Nab-Paclitaxel Induces Sensitivity to Paclitaxel in Paclitaxel Resistant Tumor Cell Lines

For drug treatment, MIA PaCa-2 or BxPC-3 cells were plated in %-well plates in RPMI medium plus 10% FBS. Parental (paclitaxel sensitive) or AbR (paclitaxel resistant) variants of the MIA PaCa-2 or BxPC-3 cell lines were used. Compound 5 was prepared in DMSO and further diluted 1:10 in RPMI medium for addition to the assay solution at a final concentration of either 0.2 or 2.0 μM. Serial dilutions of Nab-paclitaxel were prepared in DMSO and further diluted 1:10 in RPMI medium for addition to the assay solution. RPMI-diluted compounds were added to each well 24-hours after cell plating. Assays were done in triplicate for each drug concentration, with cell viability measured at 3 or 7 days after compound addition. The number of viable cells was measured using the CellTiter-Glo assay (Promega) according to the manufactures instructions. Luminosity per well was determined and the signal intensity was analyzed versus drug concentration. For each FASN inhibitor, the concentration of drug resulting in 50% inhibition of the maximum signal was determined, and this value was reported as the IC₅₀.

Compound 2 was tested in an in-vitro model of paclitaxel-resistant pancreatic cancer to evaluate whether FASN inhibition can reverse resistance in tumor cells with acquired drug resistance. Compound 2 or DMSO was added to MIA PaCa-2 or BxPC-3 pancreatic cancer cells at either 0.2 or 2.0 μM. A 3-fold serial-dilution dose response of Nab-paclitaxel was added to the cells 1 hour after Compound 2 addition. In the paclitaxel resistant cells (AbR), Compound 2 shifted the Nab-paclitaxel IC₅₀value between 2.2 and 3.1 fold. The Nab-paclitaxel IC₅₀value was not significantly affected in the parental (paclitaxel sensitive) cell lines. Compound 2 shifted the BxPC-3 Nab-paclitaxel IC₅₀value 2.2 fold. Similarly, the MIA PaCa-2 Nab-paclitaxel IC₅₀value was shifted 3.1 fold (Table 1).

Compound 5 was tested in an in-vitro model of paclitaxel-resistant pancreatic cancer to evaluate whether FASN inhibition can reverse resistance in tumor cells with acquired drug resistance. Compound 5 or DMSO was added to MIA PaCa-2 or BxPC-3 pancreatic cancer cells at either 0.2 or 2.0 μM. A 3-fold serial-dilution dose response of Nab-paclitaxel was added to the cells 1 hour after Compound 5 addition. In the paclitaxel resistant cells (AbR), Compound 5 shifted the Nab-paclitaxel IC₅₀value between 2.7 and 5.6 fold. The Nab-paclitaxel IC₅₀value was not significantly affected in the parental (paclitaxel sensitive) cell lines. Compound 5 shifted the BxPC-3 Nab-paclitaxel IC₅₀value 4.0 and 5.6 fold. Similarly, the MIA PaCa-2 Nab-paclitaxel IC₅₀value was shifted 2.7 and 3.4 fold (Table 2). When BxPC-3 cells are treated with Nab-paclitaxel and Compound 5 in the presence of 50 μM exogenous palmitate (the product of FASN) the IC₅₀value is not shifted (Table 3) demonstrating that Compound 5 is acting through inhibition of FASN to sensitize the cells to Nab-paclitaxel.
