## Background
FIELD OF THE INVENTION
The present invention is directed to imidazolin-5-one derivatives, pharmaceutical compositions containing them, and their use as FASN inhibitors, in for example, the treatment of cancer, obesity related disorders, and liver related disorders.
BACKGROUND OF THE INVENTION
Fatty acid synthase (FASN) is a key enzyme for the synthesis of long-chain fatty acids from acetyl-coenzyme A (CoA) and malonyl-CoA that uses reduced nicotinamide adenine dinucleotidephosphate as a cofactor. The final step in the de novo synthesis of fatty acids in mammalians is carried out by FASN, a 250 kDa protein containing 7 functional domains. Through an iterative enzymatic reaction, FASN produces palmitate starting from the substrates acetylCoA and malonylCo, using NADPH as a cofactor (See, MAIER, T., et al., “Architecture of mammalian fatty acid synthase at 4.5 Å resolution”, Science, 2006, pp 1258-1262, Vol. 311).
FASN is minimally expressed in most normal human tissues except the liver and adipose tissue, where it is expressed at high levels. Except for these lipogenic tissues (such as liver, lactating breast, fetal lung, and adipose tissue), FASN has a low expression in normal cells which use fatty acids from the diet, while tumor cells largely depend on de novo fatty acid synthesis. FASN expression is highly up-regulated in various tumors, e.g. prostate, breast, colon, and lung cancer (See, SWINNEN, J. V., et al., “Stimulation of tumor-associated fatty acid synthase expression by growth factor activation of the sterol regulatory element-binding protein pathway”. Oncogene, 2000, pp 5173-5181, Vol 19; KUHAJA, F. P., “Fatty-acid synthase and human cancer: new perspectives on its role in tumor biology”, Nutrition, 2000, pp 202-208, Vol. 16).
FASN overexpression leads to growth and survival advantage to the tumors achieved through multiple mechanisms. Firstly, it provides lipids for membrane synthesis. Moreover, the more saturated lipid composition of the membranes increases resistance to chemotherapy. FASN also contributes to improved growth factor receptor expression in lipid rafts (See, SWINNEN, J. V., et al., “Fatty acid synthase drives the synthesis of phospholipids partitioning into detergent resistant membrane microdomains”, Biochem. Biophys. Res. Commun., 2000, pp 898-903, Vol. 302; MENENDEZ, J. A., et al., “Inhibition of fatty acid synthase (FAS) suppresses HER2/neu (erbB-2) oncogene overexpression in cancer cells”, Proc. Natl Acad. Sci. USA, 2004, pp 10715-10720, Vol. 101), and improved cell signaling. Lastly, the NAPDPH consumption during palmitate synthesis in tumor cells keeps the redox balance in check.
In tumor cells, but not in normal cells, siRNA knock down or pharmacological inhibition of FASN results in apoptosis in vitro, and in a delayed tumor growth in vivo. The role of FASN as a potential oncogene has been further established in mouse models. Transgenic mouse models with FASN over expression in the prostate develop invasive prostate cancer in the presence of AR (See, MIGITA, et al., “Fatty Acid Synthase: A Metabolic Enzyme and Candidate Oncogene in Prostate Cancer”, J Natl. Cancer Inst., 2009, pp 519-532, Vol. 101). It has been proposed that FASN exerts its oncogenic effect by inhibiting the intrinsic pathway of apoptosis. Androgens and epidermal growth factor (EGF) up-regulate FASN expression and activity. In addition, FASN is also over expressed in androgen-independent prostate cancers most likely through activation of the PI3K/Akt pathway (See, BANDYOPADHYAY, S., et al., “FAS expression inversely correlates with PTEN level in prostate cancer and a PI-3 kinase inhibitor synergizes with FAS siRNA to induce apoptosis”, Oncogene, 2005, pp 5389-5395, Vol. 24; VAN DE DANDE, T., et al., “Role of the phosphatidylinositol 3′-kinase/PTEN/Akt kinase pathway in the overexpression of fatty acid synthase in LNCaP prostate cancer cells”, Cancer Res., 2002, pp 642-646, Vol. 62; PORTSMANN, T., et al., “PKB/AKT induces transcription of enzymes involved in cholesterol and fatty acid biosynthesis via activation of SREBP”, Oncogene, 2005, pp 6465-6481, Vol. 24). Thus, FASN is emerging as an important target for cancer therapy.
Since FASN expression is markedly increased in several human cancers compared with the corresponding normal tissue, and FASN over-expression in tumors has been associated with a poor prognosis, FASN inhibitors are viewed as potential therapeutics for the treatment of cancer. There remains a need for pharmaceutical agents for the treatment of a variety of cancers, including breast, prostate, head, neck, skin, lung, ovary, endometrium, thyroid, colon, rectum, esophagus, stomach, kidney, liver, bladder, pancreas, brain, blood, bone, and others.
FASN inhibitors have also shown promise in the treatment of other FASN-mediated diseases, disorders or conditions, such as obesity lack of appetite control and inflammatory conditions. Additionally, FASN has been implicated in diabetes and/or regulation of the general wellness of the liver, and therefore has potential in the treatment of obesity, Type II diabetes mellitus, Syndrome X and disorders of the liver; for the treatment of which there remains a need for pharmaceutical agents.

The compounds may also be resolved by formation of diastereomeric esters or amides, followed by chromatographic separation and removal of the chiral auxiliary. Alternatively, the compounds may be resolved using a chiral HPLC column.
Additionally, chiral HPLC against a standard may be used to determine percent enantiomeric excess (% ee). The enantiomeric excess may be calculated as follows

[(Rmoles−Smoles)/(Rmoles+Smoles)]×100%

where Rmoles and Smoles are the R and S mole fractions in the mixture such that Rmoles+Smoles=1. The enantiomeric excess may alternatively be calculated from the specific rotations of the desired enantiomer and the prepared mixture as follows:

For preparing solid compositions such as tablets, the principal active ingredient is mixed with a pharmaceutical carrier, e.g. conventional tableting ingredients such as corn starch, lactose, sucrose, sorbitol, talc, stearic acid, magnesium stearate, dicalcium phosphate or gums, and other pharmaceutical diluents, e.g. water, to form a solid preformulation composition containing a homogeneous mixture of a compound of the present invention, or a pharmaceutically acceptable salt thereof. When referring to these preformulation compositions as homogeneous, it is meant that the active ingredient is dispersed evenly throughout the composition so that the composition may be readily subdivided into equally effective dosage forms such as tablets, pills and capsules. This solid preformulation composition is then subdivided into unit dosage forms of the type described above containing from about 0.01 mg to about 1,000 mg, or any amount or range therein, of the active ingredient of the present invention. The tablets or pills of the novel composition can be coated or otherwise compounded to provide a dosage form affording the advantage of prolonged action. For example, the tablet or pill can comprise an inner dosage and an outer dosage component, the latter being in the form of an envelope over the former. The two components can be separated by an enteric layer which serves to resist disintegration in the stomach and permits the inner component to pass intact into the duodenum or to be delayed in release. A variety of material can be used for such enteric layers or coatings, such materials including a number of polymeric acids with such materials as shellac, cetyl alcohol and cellulose acetate.
The liquid forms in which the novel compositions of the present invention may be incorporated for administration orally or by injection include, aqueous solutions, suitably flavored syrups, aqueous or oil suspensions, and flavored emulsions with edible oils such as cottonseed oil, sesame oil, coconut oil or peanut oil, as well as elixirs and similar pharmaceutical vehicles. Suitable dispersing or suspending agents for aqueous suspensions, include synthetic and natural gums such as tragacanth, acacia, alginate, dextran, sodium carboxymethylcellulose, methylcellulose, polyvinyl-pyrrolidone or gelatin.
The method of treating disorders described in the present invention may also be carried out using a pharmaceutical composition comprising, consisting of and/or consisting essentially of any of the compounds as defined herein and a pharmaceutically acceptable carrier. The pharmaceutical composition may contain between about 0.01 mg and about 1000 mg of the compound, or any amount or range therein; preferably from about 1.0 mg to about 500 mg of the compound, or any amount or range therein, and may be constituted into any form suitable for the mode of administration selected. Carriers include necessary and inert pharmaceutical excipients, including, but not limited to, binders, suspending agents, lubricants, flavorants, sweeteners, preservatives, dyes, and coatings. Compositions suitable for oral administration include solid forms, such as pills, tablets, caplets, capsules (each including immediate release, timed release and sustained release formulations), granules, and powders, and liquid forms, such as solutions, syrups, elixers, emulsions, and suspensions. Forms useful for parenteral administration include sterile solutions, emulsions and suspensions.
Advantageously, compounds of the present invention may be administered in a single daily dose, or the total daily dosage may be administered in divided doses of two, three or four times daily. Furthermore, compounds for the present invention can be administered in intranasal form via topical use of suitable intranasal vehicles, or via transdermal skin patches well known to those of ordinary skill in that art. To be administered in the form of a transdermal delivery system, the dosage administration will, of course, be continuous rather than intermittent throughout the dosage regimen.
For instance, for oral administration in the form of a tablet or capsule, the active drug component can be combined with an oral, non-toxic pharmaceutically acceptable inert carrier such as ethanol, glycerol, water and the like. Moreover, when desired or necessary, suitable binders; lubricants, disintegrating agents and coloring agents can also be incorporated into the mixture. Suitable binders include, without limitation, starch, gelatin, natural sugars such as glucose or beta-lactose, corn sweeteners, natural and synthetic gums such as acacia, tragacanth or sodium oleate, sodium stearate, magnesium stearate, sodium benzoate, sodium acetate, sodium chloride and the like. Disintegrators include, without limitation, starch, methyl cellulose, agar, bentonite, xanthan gum and the like.
The liquid forms in suitably flavored suspending or dispersing agents such as the synthetic and natural gums, for example, tragacanth, acacia, methylcellulose and the like. For parenteral administration, sterile suspensions and solutions are desired. Isotonic preparations which generally contain suitable preservatives are employed when intravenous administration is desired.
To prepare a pharmaceutical composition of the present invention, a compound of formula (I) as the active ingredient is intimately admixed with a pharmaceutical carrier according to conventional pharmaceutical compounding techniques, which carrier may take a wide variety of forms depending of the form of preparation desired for administration (e.g. oral or parenteral). Suitable pharmaceutically acceptable carriers are well known in the art. Descriptions of some of these pharmaceutically acceptable carriers may be found in The Handbook of Pharmaceutical Excipients, published by the American Pharmaceutical Association and the Pharmaceutical Society of Great Britain.
Methods of formulating pharmaceutical compositions have been described in numerous publications, including Pharmaceutical Dosage Forms: Tablets, Second Edition, Revised and Expanded, Volumes 1-3, edited by Lieberman et al; Pharmaceutical Dosage Forms: Parenteral Medications, Volumes 1-2, edited by Avis et al; and Pharmaceutical Dosage Forms: Disperse Systems, Volumes 1-2, edited by Lieberman et al; published by Marcel Dekker, Inc.
Compounds of this invention may be administered in any of the foregoing compositions and according to dosage regimens established in the art whenever treatment of disorders mediated by inhibition of fatty acid synthase (FASN) enzyme, as described herein, is required.
The daily dosage of the products may be varied over a wide range from about 0.01 mg to about 1,000 mg per adult human per day, or any amount or range therein. For oral administration, the compositions are preferably provided in the form of tablets containing about 0.01, 0.05, 0.1, 0.5, 1.0, 2.5, 5.0, 10.0, 15.0, 25.0, 50.0, 100, 150, 200, 250, 500 and 1000 milligrams of the active ingredient for the symptomatic adjustment of the dosage to the patient to be treated. An effective amount of the drug is ordinarily supplied at a dosage level of from about 0.01 mg/kg to about 300 mg/kg of body weight per day, or any amount or range therein. Preferably, the range is from about 0.5 to about 50.0 mg/kg of body weight per day, or any amount or range therein. More preferably, from about 0.75 to about 15.0 mg/kg of body weight per day, or any amount or range therein. More preferably, from about 1.0 to about 7.5 mg/kg of body weight per day, or any amount or range therein. The compounds may be administered on a regimen of 1 to 4 times per day.
Optimal dosages to be administered may be readily determined by those skilled in the art, and will vary with the particular compound used, the mode of administration, the strength of the preparation, the mode of administration, and the advancement of the disease condition. In addition, factors associated with the particular patient being treated, including patient age, weight, diet and time of administration, will result in the need to adjust dosages.
One skilled in the art will recognize that, both in vivo and in vitro trials using suitable, known and generally accepted cell and/or animal models are predictive of the ability of a test compound to treat or prevent a given disorder.
One skilled in the art will further recognize that human clinical trails including first-in-human, dose ranging and efficacy trials, in healthy patients and/or those suffering from a given disorder, may be completed according to methods well known in the clinical and medical arts.
The following Examples are set forth to aid in the understanding of the invention, and are not intended and should not be construed to limit in any way the invention set forth in the claims which follow thereafter.

Biological Example 1
Fatty Acid Synthase (FASN) Inhibition Scintillation Proximity Assay
In this assay, inhibition of FASN activity is measured using 3H-acetyl-CoA and malonyl-CoA as substrates. 3H-Acetyl CoA is converted to 3H-palmitate through a series of reactions by the FASN protein, which contains 7 functional domains and carries out 7 enzymatic reactions to ultimately produce 3H-palmitate. The assay principle is based upon the fact that 3H-acetyl-CoA is hydrophilic and the end product, 3H-palmitate is hydrophobic. The hydrophobic 3H-palmitate binds to scintillation proximity assay (SPA) imaging beads (resulting in light emission from the imaging beads) whereas the hydrophilic 3H-acetyl-CoA does not bind to the imaging beads (and therefore does not result in light emission from the imaging beads).
10 μL assay buffer (100 mM KH2PO4 pH 7.5, 1 mM DTT) (20 μL in blanks) was added to a 384-well white Opti Plate plate (Perkin Elmer). 0.9 μL test compound (at concentrations of 30 μM, 10 μM, 3 μM, 1 μM, 0.30 μM, 0.10 μM, 0.03 μM and 0.01 μM)/DMSO and 10 μL hFASN enzyme (full length, 300 ng, purified in house) or 10 μL assay buffer was added to the wells. Then 10 μL 450 μM NADPH (Sigma N7505), 18.75 μM [3H]-acetyl-CoA (Perkin Elmer NET-290L), 150 μM malonyl-CoA (Sigma M4263) were added, mixed and incubated at room temperature for 60 minutes. The reaction was stopped by adding 20 μL Streptavidin coupled imaging beads (25 mg/ml). After incubation for 30 minutes at room temperature in the dark, the 384 well plate was centrifuged at 1500 rpm for 3 minutes and was measured after at least 24 hrs by the LEADseekerTM, measuring emission using a 610±20 nm pass filter. (Bays, N. W., et al., “A simplified scintillation proximity assay for fatty acid synthase activity: development and comparison with other FAS activity assays”, J. Biomol. Screen., 2009, pp 636-642, Vol. 14(6).)
Raw data generated by the instrument were normalized to % Controlmin values, which were calculated as:

% Controlmin=100*(x−mLC)/(mHC−mLC)

where mLC and mHC were the means of the low control wells and high control wells on the plate, after manual exclusion of outliers. A plot of Controlmin versus test compound concentration was fitted to a 4-parameter logistic curve using a non-linear least squares regression method. From the plot, an IC50 (concentration at which 50% inhibition is achieved) was calculated. pIC50 values were calculated as −log(IC50), when IC50 is expressed in molar units.
Representative compounds of formula (I) the present invention were tested according to the procedure as described in Biological Example 1 above, with results as listed in Table BIO-1, below. Where a compound was tested more than once, the pIC50 value listed below represents the mean of the measurements. Wherein the results listed below, the pIC50 value is preceded with a “ ̃”, the “ ̃” indicates that the standard error of the pIC50 value, as estimated by the non-linear regression algorithm, is larger than 0.5. This corresponds to a factor of uncertainly on the pIC50 that is larger than square root of 10 (>3.162).

Biological Example 2
Fatty Acid Synthase Keto-reductase Domain (FASN KR) Inhibition
10 μL assay buffer (100 mM KH2PO4 pH 7.5) was added to a 384-well clear plate (costar 3702). 0.3 μL compound (at concentrations of 30 μM, 10 μM, 3 μM, 1 μM, 0.30 μM, 0.10 μM, 0.03 μM and 0.01 μM)/DMSO, 10 μL hFASN enzyme (full length, 300 ng, purified in house) and 360 μM NADPH (except in blank) were then added. Then, 10 μL 180 mM ethyl acetoacetate (Aldrich 688983) was added, mixed and immediately thereafter, the absorbance at 340 nm (T1) by Multiscan (Labsystems) was measured. After 20 minutes incubation at room temperature the plate was measured again (T2).
Enzymatic activity of FASN KR was measured as the oxidation of NADPH to NADP+ (a decrease in NADPH signal was observed at OD 340 nm). The decrease in absorbance was calculated as (Absorbance before incubation T1)−(Absorbance following incubation T2).
Raw data generated by the instrument were normalized to % Controlmin values, which were calculated as:

% Controlmin=100*(x−mLC)/(mHC−mLC)

where mLC and mHC were the means of the low control wells and high control wells on the plate, after manual exclusion of outliers. A plot of Controlmin versus test compound concentration was fitted to a 4-parameter logistic curve using a non-linear least squares regression method. From the plot, an IC50 (concentration at which 50% inhibition is achieved) was calculated. pIC50 values were calculated as −log(IC50), when IC50 is expressed in molar units.

Biological Example 3
A2780 Ovarian Cell Proliferation Assay in Lipid Reduced Medium, with and without Palmitate
The biological assays described below correspond to comparative assays for ovarian cell proliferation. The assay procedure described below which includes addition of added palmitate correspond to the control relative to the assay procedure which does not include addition of the palmitate. Compounds active in the absence of palmitate would not be expected to be active in the control.
With Palmitate:
2500 cells were seeded in a 96-well clear well plate in 200 μL RPM11640 with 10% Fetal Calf Serum (Hyclone), and incubated at 37° C., 5% CO2. Blanks were wells without cells. The next day the culture medium was aspirated and replaced by 160 μL culture medium with 10% Lipid-Reduced Serum (LRS, Hyclone). 20 μL test compound (at concentrations of 30 μM, 10 μM, 3 μM, 1 μM, 0.30 μM, 0.10 μM, 0.03 μM and 0.01 μM)/DMSO dilution followed by 20 μL palmitate-BSA solution were added to a final concentrations of 0.2% DMSO, 25 μM palmitate (Sigma, P0500, 10 mM stock solution in ethanol) 0.2% fatty-acid-free BSA, 0.25% ethanol. After 96 h incubation, an MTT assay was performed. The absorbance was measured at 544 nm on a SPECTRAMAX.
A best fit curve was fitted by a minimum sum of squares method, plotting Controlmin versus test compound concentration. From the plot, an IC50 (concentration at which 50% inhibition is achieved) was calculated. pIC50 values, presented in the Table below, were calculated as −log(IC50).
Without Palmitate:
2500 cells were seeded in a 96-well clear well plate in 200 μL RPM11640 with 10% Fetal Calf Serum (Hyclone), and incubated at 37° C., 5% CO2. Blanks were wells without cells. The next day the culture medium was aspirated and replaced by 160 μL culture medium with 10% Lipid-Reduced Serum (LRS, Hyclone). 20 μL test compound (at concentrations of 30 μM, 10 μM, 3 μM, 1 μM, 0.30 μM, 0.10 μM, 0.03 μM and 0.01 μM)/DMSO dilution followed by 20 μL ethanol-BSA solution were added to a final concentrations of 0.2% DMSO, 0.2% fatty-acid-free BSA, 0.25% ethanol. After 96 h incubation an MTT assay was performed. The absorbance was measured at 544 nm on a SPECTRAMAX.
Raw data generated by the instrument were normalized to % Controlmin values, which were calculated as:

% Controlmin=100*(x−mLC)/(mHC−mLC)

Representative compounds of the present invention were tested according to the procedure as described in Biological Example 3 above, with results as listed in Table BIO-3, below. Where a compound was tested more than once, the pIC50 value listed below represents the mean of the measurements. Wherein the results listed below, the pIC50 value is preceded with a “ ̃”, the “ ̃” the “ ̃” indicates that the standard error of the pIC50 value, as estimated by the non-linear regression algorithm, is larger than 0.5.

For the proliferation experiment 1500 LNCaP_Vancouver cells per well were seeded in a 384-well black with clear bottom plate (costar 3712BC) in 40 μl RPMI-1640, 10% Lipid reduced serum (LRS, Hyclone), 50 μg/ml Gentamicin and 2 mM Glutamine and incubated at 37° C., 5% CO2. The next day 10 μl of test compound/DMSO diluted in medium was added (3E-5M, 1E-5M, 3E-6M, 1E-6M, 3E-7M, 1E-7M, 3E-8M, 1E-8M final concentration). Compounds were tested in duplicate. After 96 h incubation at 37° C., 5% CO2 25 μl ATP-glow mix was added. The plate was incubated for 30 min at 37° C. and luminescence was measured with the Envision.
Example 4b
In Vitro PC-3M-Luc-C6 Prostate Cell Proliferation Assay in Lipid Reduced Medium
PC-3M-Luc-C6 prostate cells were obtained from Xenogen Corporation. Cells were maintained in MEM supplementend with 10% Fetal Calf Serum (FCS, Hyclone), 2 mM glutamine, 1 mM sodium pyruvate, 1% BME vitamins (available from for example, Sigma Aldrich), 0.1 mM non Essential Amino Acid and 50 μg/ml Gentamicin. The cells were passaged twice a week.
1000 PC-3M-Luc-C6 prostate cells (Xenogen) were seeded in a 384-well black with clear bottom plate (costar 3712BC) in 40 μl MEM, 10% LRS (Hyclo ne), 50 μg/ml Gentamicin, 2 mM Glutamine, 1 mM Sodium pyruvaat, 1% BME vitamins and 0.1 mM non Essential Amino Acid and incubated at 37° C., 5% CO2. The next day 10 μl test compound/DMSO diluted in medium was added (3E-5M, 1E-5M, 3E-6M, 1E-6M, 3E-7M, 1E-7M, 3E-8M, 1E-8M final concentration). Compounds were tested in duplicate. After 96 h incubation at 37° C., 5% CO2 25 μl ATP-glow mix was added. The plate was incubated for 30 min at 37° C. and luminescence was measured with the Envision.
Analysis: Determination of pIC50 Values
pIC50 values were calculated as follows. Raw data generated by the instruments were normalized to % Controlmin values, which were calculated as:

% Controlmin=100*(x−mLC)/(mHC−mLC),

where mLC and mHC are the means of the low control wells and high control wells on the plate, after manual exclusion of outliers. The relation between the % Controlmin values and concentration was fitted to a 4-parameter logistic curve using a non-linear least squares regression method to determine the pIC50 value. Outlying data points were excluded manually to get a correct fit. The pIC50 corresponds to −log 10(IC50), if the IC50 is expressed in molar units (http://www.ncbi.nlm.nih.qov/books/NBK91994). The IC50 parameter was always determined by non-linear regression, but one or more of the other parameters may have been held fixed on a relevant input value, such as 0 for the bottom values.
For dose response curves with FASN inhibitors in LNCaP_Vancouver or PC-3M-Luc_C6 cells the curves bottom out around 30 to 40% of the control value. A standard fit PL2, forcing the lower bound to this level was used. For those test compounds which did not exhibit FASN related toxicities (but other non-target related cellular toxicity), the % control value may go to 0, and curve fit was calculated using 0% as lower bound.
Representative compounds of the present invention were tested according to the procedure as described in Biological Example 4a and 4b above, with results as listed in Table BIO-4, below. Where a compound was tested more than once, the pIC50 value listed below represents the mean of the measurements. Wherein the results listed below, the pIC50 value is preceded with a “ ̃”, the “ ̃” the “ ̃” indicates that the standard error of the pIC50 value, as estimated by the non-linear regression algorithm, is larger than 0.5. This corresponds to a factor of uncertainly on the pIC50 that is larger than square root of 10 (>3.162).

Biological Example 5
Prophetic Example
14C-acetate Incorporation in HEPG2 Liver Cells
HepG2 liver cells are obtained from the American Type Culture Collection. Cells are seeded in a 24-well plate at 7.105 cells/well in 400 μL MEM with 10% FCS (Hyclone). 100 μL of test compound dilution (25 μM to 5 μM final) is added and plates are incubated for 4 hours at 37° C. in 5% CO2. 50 μL of 14C-acetic acid (Acetic acid, sodium salt (1,2-14C): Amersham CFA13; 50-62 mCi/mMol, 200 μCi/ml (7.4 mBq/ml)) diluted 1/50 in medium is added and plates are incubated for another 2 h at 37° C. in 5% CO2. Medium is aspirated, and lipids are extracted from the cells by 3 rounds of chloroform:methanol:MgSO4 mixture and centrifugation steps (2 min at 10000 rpm). Each time the upper layer is removed. Finally the remaining organic layer is evaporated under nitrogen gas, the pellet are dissolved in 500 μL heptanes and in 3 ml of scintillation fluid added to scintillation tubes. Incorporated 14C-labelled is counted in a Pachard, Tri-Carb Liquid scintillation counter. (2 minutes)
Biological Example 6
Prophetic Example Analysis of Intact Phospholipid Species by Electrospray Ionization Tandem Mass Spectrometry
PC-3 prostate and A2780 ovarian cells are obtained from the American Type Culture Collection. Cells are cultured in HamF12 or RPMI 1640 respectively, supplemented with 10% FCS (Invitrogen). Palmitic acid (Sigma) is complexed to fatty acid-free bovine serum albumin (Invitrogen). Cells are cultured for 72 hours in the presence or absence of test compound (10 μM to 0.1 μM). Xenografts are collected after 21 days treatment with or without compound (100-10 mg/kg).
Tissue or cells are homogenized in 1 N HCl/CH3OH (1:8, v/v). CHCl3, 200 μg/mL of the antioxidant 2,6-di-tert-butyl-4-methylphenol (Sigma; ref. 29), and lipid standards are added. The organic fractions are evaporated and reconstituted in CH3OH/CHCl3/NH4OH (90:10:1.25, v/v/v). Phospholipids are analyzed by electrospray ionization tandem mass spectrometry (ESI-MS/MS) on a hybrid quadrupole linear ion trap mass spectrometer (4000 QTRAP system, Applied Biosystems) equipped with a robotic nanoflow/ion source (Advion Biosciences). The collision energy is varied as follows: precursor ion m/z 184, 50 eV; neutral loss of 141, 35 eV; neutral loss of 87, −40 eV; precursor ion m/z 241, −55 eV. The system is operated in the multiple reaction monitoring (MRM) mode for quantification of individual species. Typically, a 3-minute period of signal averaging is used for each spectrum. Data are corrected for 13C isotope effects if the contribution is >10%. Corrected data were presented as heat maps using the HeatMap Builder software (Clifton Watt, Stanford University).
Biological Example 7
Prophetic Example Xenograft Hematological Assay
Animals:
Male NMRI-nude mice (obtained from Janvier) are used for the study. Mice with an initial weight of approximately 20 to 25 g are obtained. The animals are habituated for one week prior to any experimental protocols/procedures being performed.
All animals are maintained under SPF (specific pathogen-free) “full barrier” conditions with free access to food and water. Mice are group housed under a 12-h light:dark cycle (lights on at 06:00 h) at a temperature of 19 to 22° C. and 35 to 40% humidity in Techniplast type-3 IVC cages. Mice are fed a standard Laboratory chow. All experiments are carried out in accordance with the European Communities Council Directives (86/609/EEC) and are approved by the local ethical committee.
Prostate Tumor Cells:
The human PC3 prostate tumor cells are cultured at 37° C. in a humidified atmosphere (5% CO2, 95% air), in F12-Ham medium supplemented with 2 mM Sodium Pyruvate, 50 μg/ml Gentamycin, 1.5 g/l Sodium Bicarbonate, 0.1 mM Non Essential Amino Acids and 10% fetal bovine calf serum. Cells are maintained as cell monolayer cultures, passaged twice weekly at 3×106 cells per T175 flask, according to the following procedure. Cells are washed with PBS (w/o Mg2+, Ca2+), before addition of trypsin-EDTA to the culture flasks. After detachment of cells, the trypsin-EDTA is inactivated by addition of complete medium. The cell suspension is then transferred to 50 ml Falcon tube and centrifuged for 3 min at 1200 rpm. Medium is aspirated, with the cells being re-suspended in an appropriate volume of complete medium. The cells are counted in a haemocytometer and their viability is assessed by 0.25% trypan blue exclusion. An appropriate volume of cell suspension is then added to either a new T175 culture flask(s) or roller bottle containing fresh medium. For large scale-up growth of PC3 prostate tumor cells, an appropriate number of roller bottles are seeded with 1.2×107 cells 1 week prior to inoculation of the mice. The medium is changed twice during this period, with the last change being the day prior to cell injection. Cells are collected as described above, with the exception that after centrifugation, the cells are re-suspended in cold (4° C.) serum free medium at 5×107 cells/ml.
Experimental Design:
Human PC3 prostate tumor cells are injected directly into the inguinal region of the male NMRI Nude mice (1×107 cells/200 μl/animal) on day 0. Approximately 35 days after inoculation, when tumor volumes reach an approximate average of 200 mm3, mice are randomized into test groups according to tumor volume, and treated for 21 days with either control (no test compound) or test compound at one of three dosage levels: 10 mg/kg, 30 mg/kg or 100 mg/kg.
Data Analysis:
For each individual animal, body weight and tumor size [using the commonly accepted formula: Tumor Volume (mm3)=(a×b2/2); where ‘a’ represents the length, and ‘b’ the width of the tumor as determined by caliper measurements], are monitored twice weekly throughout the study. A sustained body weight loss greater than 15% of the initial body weight is considered as clinical toxicity, with the animal removed from the study and sacrificed. Clinical signs of toxicity include, but are not limited to, persistent anorexia or dehydration, posture, moribund, lethargy, hypothermia and/or labored respiration (according to the UKCCCR guidelines for welfare of animals in preclinical in vivo tumor models)
A time-course of tumor growth is expressed as median values, or normalized to initial tumor volume on the day treatment started and expressed as mean±SEM (8 to 10 animals per group). For pre-established tumors, relative tumor volumes is calculated for each mouse (treated tumor volume/tumor volume on day 0) and expressed as mean±SEM for each treatment group. Twenty-four hours after the last treatment, animals are sacrificed, tumors excised and weighed. The anti-tumor effect of test compound versus control is determined and represented by a bar chart of median values ±25/75 and 10/90 percentiles. Statistical significance is indicated by one-sided p-values from Wilcoxon-Mann-Whitney analysis (Wilcoxon rank sum test), with p<0.05 considered statistically significant. Treatment/control (T/C) ratios are calculated based on final relative tumor volumes, using the NCI criteria—“The effective criteria for T/C ratios is 42%”.
Biological Example 8
In Vivo MaCoA Determination in NCI-H460 Xenografts
Test System
All experiments will be carried out in accordance with the European Communities Council Directives (86/609/EEC) and were approved by the local ethical committee.
Human NCI-H460 tumor cells (ATCC) were cultured at 37° C. in a humidified atmosphere (5% CO2, 95% air), in RPMI 1640 Medium supplemented with 10 mM HEPES, Glucose 4.5 g/l, 50 μg/ml Gentamycin, 1 mM Sodium Pyruvate, L-glutamine 2 mM and 10% fetal bovine calf serum (FBS). Cells were maintained as adherent epithelial cells being passaged once weekly at 10×10E6 cells per T300 using the following procedure. Briefly cells were washed with PBS (w/o Mg2+, Ca2+), before addition of trypsin-EDTA to the culture flasks. After detachment of cells the trypsin-EDTA was inactivated by addition of complete medium. Cell suspension was transferred to 50 ml Falcon tube and centrifuged for 3 min at 1200 rpm. Medium was aspirated, with the cells re-suspended in an appropriate volume of complete medium. The cells were counted in a cell counter (haemocytometer) and their viability assessed by 0.25% trypan blue exclusion. Last change of medium was performed 24 hours before cell collection. Cells were collected as described above except re-suspending after centrifugation in cold (4° C.) serum free medium at 5×107 cells/ml.
Male NMRI-nude mice (obtained from Janvier) were injected subcutaneously with 1×107 cells total in a 200 μl volume. Mice were dosed when tumors reach an average size of 300 mm3, with 3 and 30 mg/kg compound, orally, BID1.5× (n=3 per condition). 4 hours after the last dose tumors were excised and divided in two pieces of about 100 to 150 mg. One portion was used for MaCoA determination, the other portion was used for compound concentration. MaCoA induction was determined as fold induction versus the solvent treatment.
Analytical Procedure for the Quantification of Malonyl Coenzyme A in Tumor Tissue by LC/MS/MS (Calibration Range 5-5000 ng/mL in Tissue Homogenate)
The raw tissue samples were kept on dry ice at all times. Tumor tissue was weighed and homogenized with 2.0 mL of 5% trifluoroacetic acid (TFA) in water with an automated homogenizer (Bertin Precellys 24 tissue homogenizer). After centrifugation, a portion of the supernatant was combined with the internal standard (Malonyl CoA 13C3 Lithium Salt).
The supernatant was subjected to solid-phase extraction (SPE). Samples were eluted with 0.1% TFA in methanol into a clean round-bottom plastic tubes. The eluent was evaporated under nitrogen, and the residue reconstituted and transferred in an HPLC vial. The standards were neat standards and the concentration applied was the final concentration for the standards in the HPLC vial.
The samples were analyzed by LC/MS/MS using a Zorbax Eclipse XDB-C8 column coupled with a triple quadrupole mass spectrometer (MDS Sciex API 5000 with TurbolonSprayTM, Negative Polarity mode). Instrument was run in MRM mode choosing appropriate transitions for analyte and internal standard.
Chromatogram peaks were integrated using the Analyst version 1.4.2 software package. A weighted (1/x2 where x equals concentration) linear regression analysis was used. The peak area ratio of malonyl CoA to the internal standard versus the nominal concentration was plotted. The slope, intercept and the correlation coefficient were calculated. The unknown concentration (x) was then calculated with the following formula:

x=(y−b)/m 

where y is the peak area ratio of unknown malonyl CoA to internal standard, b is the y intercept and m is the slope.
Compound #72 was dissolved in a 9:1 mixture of PEG400:ethanol at a concentration of 3 mg/mL, and tested according to the procedure as described above, with results as listed in Table BIO-8, below.
