BACKGROUND OF THE INVENTION
Cancer is the leading cause of death in developed countries and the second leading cause of death in developing countries. Deaths from cancer worldwide are projected to continue rising, with an estimated 12 million deaths in 2030. While substantial progress has been made in developing effective therapies, there is a need for additional therapeutic modalities that target cancer and related diseases.
The complexity of cancer disease arises after a selection process for cells with acquired functional capabilities to enhance survival and/or resistance towards apoptosis and a limitless proliferative potential. In addition, bi-direction interaction of cancer cells and stromal cells provides further advantage of cancer cell survival and distant metastasis to the secondary organs and tissues [Liotta L A, Kohn E C. The microenvironment of the tumour-host interface. Nature 411:375, 2001]. Furthermore, cancer stem cells (CSCs) represent the apex in the hierarchical model of tumor genesis, heterogeneity and metastasis. CSCs possess the capacity for unlimited selfrenewal, the ability to give rise to progeny cells, and also an innate resistance to cytotoxic therapeutics [Corbin E. Meacham and Sean J. Morrison. Tumour heterogeneity and cancer cell plasticity. [Nature 501:328, 2013]. Thus, there is need to develop drugs for cancer therapy addressing distinct features of established tumors.
The discovery that Drosophila segment polarity gene Wingless had a common origin with the murine oncogene Int-1 led to intensive studies on Wnt signalling pathway and identification of 19 mammalian Wnts and 10 Wnt receptors [Rijsewijk F, Schuermann M, Wagenaar E, Parren P, Weigel D, Nusse R. The Drosophila homolog of the mouse mammary oncogene int-1 is identical to the segment polarity gene wingless. Cell. 1987; 50: 649-57.]. Wnts are secreted glycoproteins which bind to cell surface receptors to initiate signaling cascades. Wnt signaling cascades have classified into two categories: canonical and non-canonical, differentiated by their dependence on β-catenin. Non-canonical Wnt pathways, such as the planar cell polarity (PCP) and Ca2+ pathway, function through β-catenin independent mechanisms. Canonical Wnt signalling is initiated when a Wnt ligand engages co-receptors of the Frizzled (Fzd) and low-density lipoprotein receptor related protein (LRP) families, ultimately leading to β-catenin stabilization, nuclear translocation and activation of target genes [Angers S, Moon R T. Proximal events in Wnt signal transduction. Nat Rev Mol Cell Biol. 2009; 10: 468-77. 68. Cadigan K M, Liu Y I. Wnt signaling: complexity at the surface. J Cell Sci. 2006; 119: 395-402. 69.

In the absence of Wnt stimulus, β-catenin is held in an inactive state by a multimeric “destruction” complex comprised of adenomatous polyposis coli (APC), Axin, glycogen synthase kinase 3β (GSK3β) and casein kinase 1α (CK1α). APC and Axin function as a scaffold, permitting GSK3β- and CK1α-mediated phosphorylation of critical residues within β-catenin. These phosphorylation events mark β-catenin for ubiquitination recognition by the E3 ubiquitin ligase β-transducin-repeat-containing protein and lead to subsequent proteasomal degradation [He X, Semenov M, Tamai K, Zeng X. LDL receptor-related proteins 5 and 6 in Wnt/beta-catenin signaling: arrows point the way. Development. 131:1663, 2004. Kimelman D, Xu W. beta-catenin destruction complex: insights and questions from a structural perspective. Oncogene 25: 7482, 2006.].
In the presence of Wnt stimulus, Axin, GSK3β and Dvl are recruited to the co-receptor complex Fzd and LRP5/6 and lead to disruption of the β-catenin destruction complex. Therefore, β-catenin is stabilized and translocated to nucleus. Once in the nucleus, β-catenin forms a complex with members of the T-cell factor/lymphoid enhancer factor (TCF/LEF) family of transcription factors, recruiting co-factors such as CBP, p300, TNIK, Bcl9 and Pygopus, and ultimately driving transcription of target genes including c-myc, Oct4, cyclin D, survivin. [Joshua C. Curtin and Matthew V. Lorenzi. Drug Discovery Approaches to Target Wnt Signaling in Cancer Stem Cells. Oncotarget 1: 552, 2010].
Tankyrases play a key role in the destruction complex by regulating the stability of the rate-limiting AXIN proteins, RNF146 and tankyrase itself. The E3 ubiquitin ligase RNF146 recognizes tankyrase-mediated PARsylation and eartags AXIN, tankyrase and itself for proteasome-mediated degradation. Thus, tankyrases control the protein stability and turnover of key components of the destruction complex, and consequently the cellular levels of β-catenin [Shih-Min A. Huang, Yuji M. Mishina, Shanming Liu, Atwood Cheung, Frank Stegmeier, et al. Tankyrase inhibition stabilizes axin and antagonizes Wnt signalling. Nature 461:614, 2009, Yue Zhang, Shanming Liu, Craig Mickanin, Yan Feng, Olga Charlat, et al. RNF146 is a poly(ADP-ribose)-directed E3 ligase that regulates axin degradation and Wnt signalling. Nature Cell Biology 13:623-629, 2011].
Aberrant regulation of the Wnt/β-catenin signaling pathway is a common feature across a broad spectrum of human cancers and evolves as a central mechanism in cancer biology. First of all, Wnt overexpression could lead to malignant transformation of mouse mammary tissue [Klaus A, Birchmeier W. Wnt signalling and its impact on development and cancer. Nat Rev Cancer 8: 387-398, 2008]. Second, tumor genome sequencing discovered the mutations in Wnt/β-catenin pathway components as well as epigenetic mechanisms that altered the expression of genes relevant to Wnt/β-catenin pathway [Ying, Y. et al. Epigenetic disruption of the WNT/beta-catenin signaling pathway in human cancers. Epigenetics 4:307, 2009]. Third, Wnt/β-catenin pathway also cooperates with other oncogenic signaling pathways in cancer and regulates tumorigenesis, growth, and metastasis [Klaus A, Birchmeier W. Wnt signalling and its impact on development and cancer. Nat Rev Cancer 8: 387-398, 2008]. In addition, there is an additional role of WNT signaling between tumor and stromal cell interaction leading to tumorigenesis and metastasis [Shahi P, Park D, Pond A C, Seethammagari M, Chiou S-H, Cho K, et al. Activation of Wnt signaling by chemically induced dimerization of LRP5 disrupts cellular homeostasis. PLoS ONE 7: e30814, 2012]. Furthermore, growing body of evidence indicates a critical role of β-catenin in CSCs [Eaves C J, Humphries R K. Acute myeloid leukemia and the Wnt pathway. N Engl J Med. 362: 2326-7, 2010; Nusse R, Fuerer C, Ching W, Harnish K, Logan C, Zeng A, ten Berge D, Kalani Y. Wnt signaling and stem cell control. Cold Spring Harb Symp Quant Biol. 73: 59-66, 2008; Reya T, Clevers H. Wnt signalling in stem cells and cancer. Nature 434: 843-50, 2005]. For example, stem-like colon cells with a high level of β-catenin signaling have a much greater tumorigenic potential than counterpart cells with low β-catenin signaling [Vermeulen L, De Sousa E M F, van der Heijden M, Cameron K, de Jong J H, Borovski T, Tuynman J B, Todaro M, Merz C, Rodermond H, Sprick M R, Kemper K, Richel D J, Stassi G, Medema J P. Wnt activity defines colon cancer stem cells and is regulated by the microenvironment. Nat Cell Biol. 12: 468-76, 2010]. Finally, activation of Wnt/β-catenin signalling pathway is also one of the major mechanism causing tumor recurrence and drug resistance. All these provide clear rationale to develop therapeutics targeting Wnt/β-catenin signaling pathway for the treatment of cancer.
One of the approaches to inhibit Wnt/β-catenin signaling pathway is to target druggable tankyrases. Tankyrase 1 (TNKS1) and tankyrase 2 (TNKS2) are poly(ADP-ribosyl)ases that are distinguishable from other members of the enzyme family by the structural features of the catalytic domain, and the presence of a sterile a-motif multimerization domain and an ankyrin repeat protein-interaction domain. Inhibition of TNKS blocks PARsylation of AXIN1 and AXIN2 and prevents their proteasomal degradation. As the consequence, TNKS inhibition enhances the activity of the β-catenin destruction complex and suppresses β-catenin nuclear transclocation and the expression of β-catenin target genes.
In addition to its function in Wnt signaling through modulation of β-catenin destruction, tankyrases are also implicated in other cellular functions, including telomere homeostasis, mitotic spindle formation, vesicle transport linked to glucose metabolism, and viral replication. In these processes, tankyrases interact with target proteins, catalyze poly (ADP-ribosyl)ation, and regulate protein interactions and stability. For example, TNKS1 controls telomere homeostasis, which promotes telomeric extension by PARsylating TRF1. TRF1 is then targeted for proteasomal degradation by the E3 ubiquitin ligases F-box only protein 4 and/or RING finger LIM domain-binding protein (RLIM/RNF12), which facilitates telomere maintenance [Donigian J R and de Lange T. The role of the poly(ADP-ribose) polymerase tankyrase1 in telomere length control by the TRF1 component of the shelterin complex. J Biol Chem 282:22662, 2007]. In addition, telomeric end-capping also requires canonical DNA repair proteins such as DNA-dependent protein kinase (DNAPK) TNKS1 stabilizes the catalytic subunit of DNAPK (DNAPKcs) by PARsylation [Dregalla R C, Zhou J, Idate R R, Battaglia C L, Liber H L, Bailey S M. Regulatory roles of tankyrase 1 at telomeres and in DNA repair: suppression of T-SCE and stabilization of DNA-PKcs. Aging 2(10):691, 2010]. Altered expression of TNKS1 and/or TNKS2, as well as genetic alterations in the tankyrase locus, have been detected in multiple tumors, e.g. fibrosarcoma, ovarian cancer, glioblastoma, pancreatic adenocarcinoma, breast cancer, astrocytoma, lung cancer, gastric cancer, and colon cancer [Lari Lehti, Nai-Wen Chi and Stefan Krauss. Tankyrases as drug targets. FEBS Journal 280: 3576, 2013]. In addition, tankyrases appear to have impact on viral infections. For example, HSV infection, it was shown that the virus cannot replicate efficiently in cells that with depletion of both TNKS1 and TNKS2.
Furthermore, a connection between tankyrases and glucose metabolism has been indicated. Thus, DNA polymorphism in a chromosomal region encoding tankyrase/methionine sulfoxide reductase A is robustly associated with early-onset obesity. TNKS1 knockout mice appeared to have reduced fat pads, suggesting a potential connection of TNKS and obesity. TNKS may also play a role in tissue fibrosis.
In summary, tankyrases are promising drug targets in regulating WNT signalling, telomere length (e.g. telomere shortening and DNA damage induced cell death), lung fibrogenesis, myelination and viral infection. The invention presented here describes a novel class of tankyrase inhibitors and their potential clinical utility for the treatment of various diseases, such as cancer, aging, metabolic diseases (e.g. diabetes and obesity), fibrosis (e.g. lung fibrogenesis) and viral infection.

The invention also includes all suitable isotopic variations of a compound of the invention. An isotopic variation of a compound of the invention is defined as one in which at least one atom is replaced by an atom having the same atomic number but an atomic mass different from the atomic mass usually or predominantly found in nature. Examples of isotopes that can be incorporated into a compound of the invention include isotopes of hydrogen, carbon, nitrogen, oxygen, phosphorus, sulphur, fluorine, chlorine, bromine and iodine, such as 2H (deuterium), 3H (tritium), 11C, 13C, 14C, 15N, 17O, 18O, 32P, 33P, 33S, 34S, 35S, 36S, 18F, 36Cl, 82Br, 123I, 124I, 125I, 129I and 131I, respectively. Certain isotopic variations of a compound of the invention, for example, those in which one or more radioactive isotopes such as 3H or 14C are incorporated, are useful in drug and/or substrate tissue distribution studies. Tritiated and carbon-14, i.e., 14C, isotopes are particularly preferred for their ease of preparation and detectability. Further, substitution with isotopes such as deuterium may afford certain therapeutic advantages resulting from greater metabolic stability, for example, increased in vivo half-life or reduced dosage requirements and hence is preferred in some circumstances. Isotopic variations of a compound of the invention can generally be prepared by conventional procedures known by a person skilled in the art such as by the illustrative methods or by the preparations described in the examples hereafter using appropriate isotopic variations of suitable reagents.
Where the plural form of the word compounds, salts, polymorphs, hydrates, solvates and the like, is used herein, this is taken to mean also a single compound, salt, polymorph, isomer, hydrate, solvate or the like.
By “stable compound’ or “stable structure” is meant 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.
The compounds of this invention optionally contain one or more asymmetric centre, depending upon the location and nature of the various substituents desired. Asymmetric carbon atoms is present in the (R) or (S) configuration, resulting in racemic mixtures in the case of a single asymmetric centre, and diastereomeric mixtures in the case of multiple asymmetric centres. In certain instances, asymmetry may also be present due to restricted rotation about a given bond, for example, the central bond adjoining two substituted aromatic rings of the specified compounds.
The compounds of the present invention optionally contain sulphur atoms which are asymmetric, such as an asymmetric sulfoxide, of structure:




for example,

in which * indicates atoms to which the rest of the molecule can be bound.

Substituents on a ring may also be present in either cis or trans form. It is intended that all such configurations (including enantiomers and diastereomers), are included within the scope of the present invention.
Preferred compounds are those which produce the more desirable biological activity. Separated, pure or partially purified isomers and stereoisomers or racemic or diastereomeric mixtures of the compounds of this invention are also included within the scope of the present invention. The purification and the separation of such materials can be accomplished by standard techniques known in the art.
The optical isomers can be obtained by resolution of the racemic mixtures according to conventional processes, for example, by the formation of diastereoisomeric salts using an optically active acid or base or formation of covalent diastereomers. Examples of appropriate acids are tartaric, diacetyltartaric, ditoluoyltartaric and camphorsulfonic acid. Mixtures of diastereoisomers can be separated into their individual diastereomers on the basis of their physical and/or chemical differences by methods known in the art, for example, by chromatography or fractional crystallisation. The optically active bases or acids are then liberated from the separated diastereomeric salts. A different process for separation of optical isomers involves the use of chiral chromatography (e.g., chiral HPLC columns), with or without conventional derivatisation, optimally chosen to maximise the separation of the enantiomers. Suitable chiral HPLC columns are manufactured by Daicel, e.g., Chiracel OD and Chiracel OJ among many others, all routinely selectable. Enzymatic separations, with or without derivatisation, are also useful. The optically active compounds of this invention can likewise be obtained by chiral syntheses utilizing optically active starting materials.
In order to limit different types of isomers from each other reference is made to IUPAC Rules Section E (Pure Appl Chem 45, 11-30, 1976).
The present invention includes all possible stereoisomers of the compounds of the present invention as single stereoisomers, or as any mixture of said stereoisomers, e.g. R- or S-isomers, or E- or Z-isomers, in any ratio.

1. SYNTHESES OF COMPOUNDS (OVERVIEW)
The compounds of the present invention can be prepared as described in the following section. Schemes 1 to 5 and the procedures described below illustrate general synthetic routes to the compounds of general formula (I) of the invention and are not intended to be limiting. It is clear to the person skilled in the art that the order of transformations as exemplified in Schemes 1 to 5 can be modified in various ways. The order of transformations as exemplified in the Schemes 1 to 5 are therefore not intended to be limiting. In addition, interconversion of any of the substituents, R1, R2, R5 and R8 can be achieved before and/or after the exemplified transformations. These modifications can be such as the introduction of protecting groups, cleavage of protecting groups, exchange, reduction or oxidation of functional groups, halogenation, metallation, substitution or other reactions known to the person skilled in the art. These transformations include those which introduce a functionality which allows for further interconversion of substituents. Appropriate protecting groups and their introduction and cleavage are well-known to the person skilled in the art (see for example T. W. Greene and P. G. M. Wuts in Protective Groups in Organic Synthesis, 3rd edition, Wiley 1999). Specific examples are described in the subsequent paragraphs. Further, it is possible that two or more successive steps may be performed without work-up being performed between said steps, e.g. a “one-pot” reaction, as is well-known to the person skilled in the art.
All reagents used for the preparation of the compounds of the invention are either commercially available or can be prepared as described.

NMR Data:
The 1H-NMR data of selected examples are listed in the form of 1H-NMR peaklists. For each signal peak the δ value in ppm is given, followed by the signal intensity, reported in round brackets. The δ value-signal intensity pairs from different peaks are separated by commas. Therefore, a peaklist is described by the general form: δ1 (intensity1), δ2 (intensity2), . . . , δi (intensityi), . . . , δn (intensityn).
The intensity of a sharp signal correlates with the height (in cm) of the signal in a printed NMR spectrum. When compared with other signals, this data can be correlated to the real ratios of the signal intensities. In the case of broad signals, more than one peak, or the center of the signal along with their relative intensity, compared to the most intense signal displayed in the spectrum, are shown. A 1H-NMR peaklist is similar to a classical 1H-NMR readout, and thus usually contains all the peaks listed in a classical NMR interpretation. Moreover, similar to classical 1H-NMR printouts, peaklists can show solvent signals, signals derived from stereoisomers of target compounds (also the subject of the invention), and/or peaks of impurities. The peaks of stereoisomers, and/or peaks of impurities are typically displayed with a lower intensity compared to the peaks of the target compounds (e.g., with a purity of >90%). Such stereoisomers and/or impurities may be typical for the particular manufacturing process, and therefore their peaks may help to identify the reproduction of our manufacturing process on the basis of “by-product fingerprints”. An expert who calculates the peaks of the target compounds by known methods (MestReC, ACD simulation, or by use of empirically evaluated expectation values), can isolate the peaks of target compounds as required, optionally using additional intensity filters. Such an operation would be similar to peak-picking in classical 1H-NMR interpretation. A detailed description of the reporting of NMR data in the form of peaklists can be found in the publication “Citation of NMR Peaklist Data within Patent Applications” (cf. Research Disclosure Database Number 605005, 2014, 1 Aug. 2014, or researchdisclosure.com/searching-disclosures). In the peak picking routine, as described in the Research Disclosure Database Number 605005, the parameter “MinimumHeight” can be adjusted between 1% and 4%. Depending on the chemical structure and/or depending on the concentration of the measured compound it may be reasonable to set the parameter “MinimumHeight”<1%.

Pharmaceutical Compositions of the Compounds of the Invention
This invention also relates to pharmaceutical compositions containing one or more compounds of the present invention. These compositions can be utilised to achieve the desired pharmacological effect by administration to a patient in need thereof. A patient, for the purpose of this invention, is a mammal, including a human, in need of treatment for the particular condition or disease. Therefore, the present invention includes pharmaceutical compositions that are comprised of a pharmaceutically acceptable carrier and a pharmaceutically effective amount of a compound, or salt thereof, of the present invention. A pharmaceutically acceptable carrier is preferably a carrier that is relatively non-toxic and innocuous to a patient at concentrations consistent with effective activity of the active ingredient so that any side effects ascribable to the carrier do not vitiate the beneficial effects of the active ingredient. A pharmaceutically effective amount of compound is preferably that amount which produces a result or exerts an influence on the particular condition being treated. The compounds of the present invention can be administered with pharmaceutically-acceptable carriers well known in the art using any effective conventional dosage unit forms, including immediate, slow and timed release preparations, orally, parenterally, topically, nasally, ophthalmically, optically, sublingually, rectally, vaginally, and the like.
For oral administration, the compounds can be formulated into solid or liquid preparations such as capsules, pills, tablets, troches, lozenges, melts, powders, solutions, suspensions, or emulsions, and may be prepared according to methods known to the art for the manufacture of pharmaceutical compositions. The solid unit dosage forms can be a capsule that can be of the ordinary hard- or soft-shelled gelatine type containing, for example, surfactants, lubricants, and inert fillers such as lactose, sucrose, calcium phosphate, and corn starch.
In another embodiment, the compounds of this invention may be tableted with conventional tablet bases such as lactose, sucrose and cornstarch in combination with binders such as acacia, corn starch or gelatine, disintegrating agents intended to assist the break-up and dissolution of the tablet following administration such as potato starch, alginic acid, corn starch, and guar gum, gum tragacanth, acacia, lubricants intended to improve the flow of tablet granulation and to prevent the adhesion of tablet material to the surfaces of the tablet dies and punches, for example talc, stearic acid, or magnesium, calcium or zinc stearate, dyes, colouring agents, and flavouring agents such as peppermint, oil of wintergreen, or cherry flavouring, intended to enhance the aesthetic qualities of the tablets and make them more acceptable to the patient. Suitable excipients for use in oral liquid dosage forms include dicalcium phosphate and diluents such as water and alcohols, for example, ethanol, benzyl alcohol, and polyethylene alcohols, either with or without the addition of a pharmaceutically acceptable surfactant, suspending agent or emulsifying agent. Various other materials may be present as coatings or to otherwise modify the physical form of the dosage unit. For instance tablets, pills or capsules may be coated with shellac, sugar or both.
Dispersible powders and granules are suitable for the preparation of an aqueous suspension. They provide the active ingredient in admixture with a dispersing or wetting agent, a suspending agent and one or more preservatives. Suitable dispersing or wetting agents and suspending agents are exemplified by those already mentioned above. Additional excipients, for example those sweetening, flavouring and colouring agents described above, may also be present.
The pharmaceutical compositions of this invention may also be in the form of oil-in-water emulsions. The oily phase may be a vegetable oil such as liquid paraffin or a mixture of vegetable oils. Suitable emulsifying agents may be (1) naturally occurring gums such as gum acacia and gum tragacanth, (2) naturally occurring phosphatides such as soy bean and lecithin, (3) esters or partial esters derived form fatty acids and hexitol anhydrides, for example, sorbitan monooleate, (4) condensation products of said partial esters with ethylene oxide, for example, polyoxyethylene sorbitan monooleate. The emulsions may also contain sweetening and flavouring agents.
Oily suspensions may be formulated by suspending the active ingredient in a vegetable oil such as, for example, arachis oil, olive oil, sesame oil or coconut oil, or in a mineral oil such as liquid paraffin. The oily suspensions may contain a thickening agent such as, for example, beeswax, hard paraffin, or cetyl alcohol. The suspensions may also contain one or more preservatives, for example, ethyl or n-propyl p-hydroxybenzoate; one or more colouring agents; one or more flavouring agents; and one or more sweetening agents such as sucrose or saccharin.
Syrups and elixirs may be formulated with sweetening agents such as, for example, glycerol, propylene glycol, sorbitol or sucrose. Such formulations may also contain a demulcent, and preservative, such as methyl and propyl parabens and flavouring and colouring agents.
The compounds of this invention may also be administered parenterally, that is, subcutaneously, intravenously, intraocularly, intrasynovially, intramuscularly, or interperitoneally, as injectable dosages of the compound in preferably a physiologically acceptable diluent with a pharmaceutical carrier which can be a sterile liquid or mixture of liquids such as water, saline, aqueous dextrose and related sugar solutions, an alcohol such as ethanol, isopropanol, or hexadecyl alcohol, glycols such as propylene glycol or polyethylene glycol, glycerol ketals such as 2,2-dimethyl-1,1-dioxolane-4-methanol, ethers such as poly(ethylene glycol) 400, an oil, a fatty acid, a fatty acid ester or, a fatty acid glyceride, or an acetylated fatty acid glyceride, with or without the addition of a pharmaceutically acceptable surfactant such as a soap or a detergent, suspending agent such as pectin, carbomers, methylcellulose, hydroxypropylmethylcellulose, or carboxymethylcellulose, or emulsifying agent and other pharmaceutical adjuvants. Illustrative of oils which can be used in the parenteral formulations of this invention are those of petroleum, animal, vegetable, or synthetic origin, for example, peanut oil, soybean oil, sesame oil, cottonseed oil, corn oil, olive oil, petrolatum and mineral oil. Suitable fatty acids include oleic acid, stearic acid, isostearic acid and myristic acid. Suitable fatty acid esters are, for example, ethyl oleate and isopropyl myristate. Suitable soaps include fatty acid alkali metal, ammonium, and triethanolamine salts and suitable detergents include cationic detergents, for example dimethyl dialkyl ammonium halides, alkyl pyridinium halides, and alkylamine acetates; anionic detergents, for example, alkyl, aryl, and olefin sulfonates, alkyl, olefin, ether, and monoglyceride sulfates, and sulfosuccinates; non-ionic detergents, for example, fatty amine oxides, fatty acid alkanolamides, and poly(oxyethylene-oxypropylene)s or ethylene oxide or propylene oxide copolymers; and amphoteric detergents, for example, alkyl-beta-aminopropionates, and 2-alkylimidazoline quarternary ammonium salts, as well as mixtures.
The parenteral compositions of this invention will typically contain from about 0.5% to about 25% by weight of the active ingredient in solution. Preservatives and buffers may also be used advantageously. In order to minimise or eliminate irritation at the site of injection, such compositions may contain a non-ionic surfactant having a hydrophile-lipophile balance (HLB) preferably of from about 12 to about 17. The quantity of surfactant in such formulation preferably ranges from about 5% to about 15% by weight. The surfactant can be a single component having the above HLB or can be a mixture of two or more components having the desired HLB.
Illustrative of surfactants used in parenteral formulations are the class of polyethylene sorbitan fatty acid esters, for example, sorbitan monooleate and the high molecular weight adducts of ethylene oxide with a hydrophobic base, formed by the condensation of propylene oxide with propylene glycol.
The pharmaceutical compositions may be in the form of sterile injectable aqueous suspensions. Such suspensions may be formulated according to known methods using suitable dispersing or wetting agents and suspending agents such as, for example, sodium carboxymethylcellulose, methylcellulose, hydroxypropylmethylcellulose, sodium alginate, polyvinylpyrrolidone, gum tragacanth and gum acacia; dispersing or wetting agents which may be a naturally occurring phosphatide such as lecithin, a condensation product of an alkylene oxide with a fatty acid, for example, polyoxyethylene stearate, a condensation product of ethylene oxide with a long chain aliphatic alcohol, for example, heptadeca-ethyleneoxycetanol, a condensation product of ethylene oxide with a partial ester derived form a fatty acid and a hexitol such as polyoxyethylene sorbitol monooleate, or a condensation product of an ethylene oxide with a partial ester derived from a fatty acid and a hexitol anhydride, for example polyoxyethylene sorbitan monooleate.
The sterile injectable preparation may also be a sterile injectable solution or suspension in a non-toxic parenterally acceptable diluent or solvent. Diluents and solvents that may be employed are, for example, water, Ringer's solution, isotonic sodium chloride solutions and isotonic glucose solutions. In addition, sterile fixed oils are conventionally employed as solvents or suspending media. For this purpose, any bland, fixed oil may be employed including synthetic mono- or diglycerides. In addition, fatty acids such as oleic acid can be used in the preparation of injectables.
A composition of the invention may also be administered in the form of suppositories for rectal administration of the drug. These compositions can be prepared by mixing the drug with a suitable non-irritation excipient which is solid at ordinary temperatures but liquid at the rectal temperature and will therefore melt in the rectum to release the drug. Such materials are, for example, cocoa butter and polyethylene glycol.
Another formulation employed in the methods of the present invention employs transdermal delivery devices (“patches”). Such transdermal patches may be used to provide continuous or discontinuous infusion of the compounds of the present invention in controlled amounts. The construction and use of transdermal patches for the delivery of pharmaceutical agents is well known in the art (see, e.g., U.S. Pat. No. 5,023,252, issued Jun. 11, 1991, incorporated herein by reference). Such patches may be constructed for continuous, pulsatile, or on demand delivery of pharmaceutical agents.
Controlled release formulations for parenteral administration include liposomal, polymeric microsphere and polymeric gel formulations that are known in the art.
It may be desirable or necessary to introduce the pharmaceutical composition to the patient via a mechanical delivery device. The construction and use of mechanical delivery devices for the delivery of pharmaceutical agents is well known in the art. Direct techniques for, for example, administering a drug directly to the brain usually involve placement of a drug delivery catheter into the patient's ventricular system to bypass the blood-brain barrier. One such implantable delivery system, used for the transport of agents to specific anatomical regions of the body, is described in U.S. Pat. No. 5,011,472, issued Apr. 30, 1991.
The compositions of the invention can also contain other conventional pharmaceutically acceptable compounding ingredients, generally referred to as carriers or diluents, as necessary or desired. Conventional procedures for preparing such compositions in appropriate dosage forms can be utilized. Such ingredients and procedures include those described in the following references, each of which is incorporated herein by reference: Powell, M.

A mixture of active ingredient in a digestible oil such as soybean oil, cottonseed oil or olive oil is prepared and injected by means of a positive displacement pump into molten gelatin to form soft gelatin capsules containing 100 mg of the active ingredient. The capsules are washed and dried. The active ingredient can be dissolved in a mixture of polyethylene glycol, glycerin and sorbitol to prepare a water miscible medicine mix.
Tablets:
A large number of tablets are prepared by conventional procedures so that the dosage unit is 100 mg of active ingredient, 0.2 mg. of colloidal silicon dioxide, 5 mg of magnesium stearate, 275 mg of microcrystalline cellulose, 11 mg of starch, and 98.8 mg of lactose. Appropriate aqueous and non-aqueous coatings may be applied to increase palatability, improve elegance and stability or delay absorption.
Immediate Release Tablets/Capsules:
These are solid oral dosage forms made by conventional and novel processes. These units are taken orally without water for immediate dissolution and delivery of the medication. The active ingredient is mixed in a liquid containing ingredient such as sugar, gelatin, pectin and sweeteners. These liquids are solidified into solid tablets or caplets by freeze drying and solid state extraction techniques. The drug compounds may be compressed with viscoelastic and thermoelastic sugars and polymers or effervescent components to produce porous matrices intended for immediate release, without the need of water.
Combination Therapies
The term “combination” in the present invention is used as known to persons skilled in the art and may be present as a fixed combination, a non-fixed combination or kit-of-parts.
A “fixed combination” in the present invention is used as known to persons skilled in the art and is defined as a combination wherein the said first active ingredient and the said second active ingredient are present together in one unit dosage or in a single entity. One example of a “fixed combination” is a pharmaceutical composition wherein the said first active ingredient and the said second active ingredient are present in admixture for simultaneous administration, such as in a formulation. Another example of a “fixed combination” is a pharmaceutical combination wherein the said first active ingredient and the said second active ingredient are present in one unit without being in admixture.
A non-fixed combination or “kit-of-parts” in the present invention is used as known to persons skilled in the art and is defined as a combination wherein the said first active ingredient and the said second active ingredient are present in more than one unit. One example of a non-fixed combination or kit-of-parts is a combination wherein the said first active ingredient and the said second active ingredient are present separately. The components of the non-fixed combination or kit-of-parts may be administered separately, sequentially, simultaneously, concurrently or chronologically staggered.

Methods of Sensitizing Cells to Radiation
In a distinct embodiment of the present invention, a compound of the present invention may be used to sensitize a cell to radiation. That is, treatment of a cell with a compound of the present invention prior to radiation treatment of the cell renders the cell more susceptible to DNA damage and cell death than the cell would be in the absence of any treatment with a compound of the invention. In one aspect, the cell is treated with at least one compound of the invention.
Thus, the present invention also provides a method of killing a cell, wherein a cell is administered one or more compounds of the invention in combination with conventional radiation therapy.
The present invention also provides a method of rendering a cell more susceptible to cell death, wherein the cell is treated with one or more compounds of the invention prior to the treatment of the cell to cause or induce cell death. In one aspect, after the cell is treated with one or more compounds of the invention, the cell is treated with at least one compound, or at least one method, or a combination thereof, in order to cause DNA damage for the purpose of inhibiting the function of the normal cell or killing the cell.
In one embodiment, a cell is killed by treating the cell with at least one DNA damaging agent. That is, after treating a cell with one or more compounds of the invention to sensitize the cell to cell death, the cell is treated with at least one DNA damaging agent to kill the cell. DNA damaging agents useful in the present invention include, but are not limited to, chemotherapeutic agents (e.g., cisplatinum), ionizing radiation (X-rays, ultraviolet radiation), carcinogenic agents, and mutagenic agents.
In another embodiment, a cell is killed by treating the cell with at least one method to cause or induce DNA damage. Such methods include, but are not limited to, activation of a cell signalling pathway that results in DNA damage when the pathway is activated, inhibiting of a cell signalling pathway that results in DNA damage when the pathway is inhibited, and inducing a biochemical change in a cell, wherein the change results in DNA damage. By way of a non-limiting example, a DNA repair pathway in a cell can be inhibited, thereby preventing the repair of DNA damage and resulting in an abnormal accumulation of DNA damage in a cell.
In one aspect of the invention, a compound of the invention is administered to a cell prior to the radiation or other induction of DNA damage in the cell. In another aspect of the invention, a compound of the invention is administered to a cell concomitantly with the radiation or other induction of DNA damage in the cell. In yet another aspect of the invention, a compound of the invention is administered to a cell immediately after radiation or other induction of DNA damage in the cell has begun.
In another aspect, the cell is in vitro. In another embodiment, the cell is in vivo.
As mentioned supra, the compounds of the present invention have surprisingly been found to effectively inhibit tankyrases and may therefore be used for the treatment or prophylaxis of diseases of uncontrolled cell growth, proliferation and/or survival, inappropriate cellular immune responses, or inappropriate cellular inflammatory responses, or diseases which are accompanied with uncontrolled cell growth, proliferation and/or survival, inappropriate cellular immune responses, or inappropriate cellular inflammatory responses, particularly in which the uncontrolled cell growth, proliferation and/or survival, inappropriate cellular immune responses, or inappropriate cellular inflammatory responses are affected by inhibition of tankyrases, such as, for example, haematological tumours, solid tumours, and/or metastases thereof, e.g. leukaemias and myelodysplastic syndrome, malignant lymphomas, head and neck tumours including brain tumours and brain metastases, tumours of the thorax including non-small cell and small cell lung tumours, gastrointestinal tumours, endocrine tumours, mammary and other gynaecological tumours, urological tumours including renal, bladder and prostate tumours, skin tumours, and sarcomas, and/or metastases thereof.

The term “treating” or “treatment” as stated throughout this document is used conventionally, e.g., the management or care of a subject for the purpose of combating, alleviating, reducing, relieving, improving the condition of, etc., of a disease or disorder, such as a carcinoma.
Methods of Treating Angiogenic Disorders
The present invention also provides methods of treating disorders and diseases associated with excessive and/or abnormal angiogenesis.
Inappropriate and ectopic expression of angiogenesis can be deleterious to an organism. A number of pathological conditions are associated with the growth of extraneous blood vessels. These include, e.g., diabetic retinopathy, ischemic retinal-vein occlusion, and retinopathy of prematurity [Aiello et al. New Engl. J. Med. 1994, 331, 1480; Peer et al. Lab. Invest. 1995, 72, 638], age-related macular degeneration [AMD; see, Lopez et al. Invest. Opththalmol. Vis. Sci. 1996, 37, 855], neovascular glaucoma, psoriasis, retrolental fibroplasias, angiofibroma, inflammation, rheumatoid arthritis (RA), restenosis, in-stent restenosis, vascular graft restenosis, etc. In addition, the increased blood supply associated with cancerous and neoplastic tissue, encourages growth, leading to rapid tumour enlargement and metastasis. Moreover, the growth of new blood and lymph vessels in a tumour provides an escape route for renegade cells, encouraging metastasis and the consequence spread of the cancer. Thus, compounds of the present invention can be utilized to treat and/or prevent any of the aforementioned angiogenesis disorders, e.g., by inhibiting and/or reducing blood vessel formation; by inhibiting, blocking, reducing, decreasing, etc. endothelial cell proliferation or other types involved in angiogenesis, as well as causing cell death or apoptosis of such cell types.
Dose and Administration
Based upon standard laboratory techniques known to evaluate compounds useful for the treatment of hyper-proliferative disorders and angiogenic disorders, by standard toxicity tests and by standard pharmacological assays for the determination of treatment of the conditions identified above in mammals, and by comparison of these results with the results of known medicaments that are used to treat these conditions, the effective dosage of the compounds of this invention can readily be determined for treatment of each desired indication. The amount of the active ingredient to be administered in the treatment of one of these conditions can vary widely according to such considerations as the particular compound and dosage unit employed, the mode of administration, the period of treatment, the age and sex of the patient treated, and the nature and extent of the condition treated.
The total amount of the active ingredient to be administered will generally range from about 0.001 mg/kg to about 200 mg/kg body weight per day, and preferably from about 0.01 mg/kg to about 20 mg/kg body weight per day. Clinically useful dosing schedules will range from one to three times a day dosing to once every four weeks dosing. In addition, “drug holidays” in which a patient is not dosed with a drug for a certain period of time, may be beneficial to the overall balance between pharmacological effect and tolerability. A unit dosage may contain from about 0.5 mg to about 1500 mg of active ingredient, and can be administered one or more times per day or less than once a day. The average daily dosage for administration by injection, including intravenous, intramuscular, subcutaneous and parenteral injections, and use of infusion techniques will preferably be from 0.01 to 200 mg/kg of total body weight. The average daily rectal dosage regimen will preferably be from 0.01 to 200 mg/kg of total body weight. The average daily vaginal dosage regimen will preferably be from 0.01 to 200 mg/kg of total body weight. The average daily topical dosage regimen will preferably be from 0.1 to 200 mg administered between one to four times daily. The transdermal concentration will preferably be that required to maintain a daily dose of from 0.01 to 200 mg/kg. The average daily inhalation dosage regimen will preferably be from 0.01 to 100 mg/kg of total body weight.
Of course the specific initial and continuing dosage regimen for each patient will vary according to the nature and severity of the condition as determined by the attending diagnostician, the activity of the specific compound employed, the age and general condition of the patient, time of administration, route of administration, rate of excretion of the drug, drug combinations, and the like. The desired mode of treatment and number of doses of a compound of the present invention or a pharmaceutically acceptable salt or ester or composition thereof can be ascertained by those skilled in the art using conventional treatment tests.
Preferably, the diseases of said method are haematological tumours, solid tumour and/or metastases thereof.
The compounds of the present invention can be used in particular in therapy and prevention, i.e. prophylaxis, of tumour growth and metastases, especially in solid tumours of all indications and stages with or without pre-treatment of the tumour growth.
Methods of testing for a particular pharmacological or pharmaceutical property are well known to persons skilled in the art.
The example testing experiments described herein serve to illustrate the present invention and the invention is not limited to the examples given.
Biological Assays:
Examples were tested in selected biological assays one or more times. When tested more than once, data are reported as either average values or as median values, wherein

    
    
        the average value, also referred to as the arithmetic mean value, represents the sum of the values obtained divided by the number of times tested, and
        the median value represents the middle number of the group of values when ranked in ascending or descending order. If the number of values in the data set is odd, the median is the middle value. If the number of values in the data set is even, the median is the arithmetic mean of the two middle values.
    
    


When no meaningful calculation of average values or median values is possible due to the existence of measurement values falling outside of the detection range of the assay (indicated by < or > in the tables below) all individual measurement values are indicated.
Examples were synthesized one or more times. When synthesized more than once, data from biological assays represent average values or median values calculated utilizing data sets obtained from testing of one or more synthetic batch.
6 BIOCHEMICAL ASSAYS
In general the potency assessment of the compounds of the present invention reveal consistent data applying orthogonal biochemical test formats (compare identical example Nos. in the tables below showing results for the TNKS1 Assay 1, Modified TNKS1 Assay 2 and Modified TNKS1 Assay 3, or for the TNKS2 Assay 1, Modified TNKS2 Assay 2 and Modified TNKS2 Assay 3). For those particular cases where the correlation of test results between different assays is less good, it could not be excluded that any differences may be due to different potencies of the compound dependent on the assay setup itself. Another factor to explain any potency differences between assays may be the use of different batches of the particular test compound applied in those orthogonal tests. Here, in some cases the test compound has been supplied as stock solution in DMSO, and in other cases the compound has been taken from solid material and dissolved freshly in DMSO solvent prior to the experiment. A different solubilization would have resulted in different apparent concentrations used for testing and would have translated into different apparent potencies.
6.1 TNKS1 Assays
TNKS1 Assay 1
The potency of the compounds according to the invention was assessed by applying an in vitro inhibition assay. The TNKS1 catalyzed NAD+-dependent ribosylation of a suitable protein substrate was detected using a commercially available biotin/streptavidin binding based assay format [TNKS1 Histone Ribosylation Assay Kit (Biotin-labeled NAD+), Catalog #80579; BPS Bioscience, San Diego, USA]. Here, the incorporation of a biotin-labeled NAD+ during the TNKS1 catalyzed ribosylation reaction was detected with a streptavidin-HRP coupled chemi-luminescent readout. The intensity of the readout signal is proportional to the incorporated NAD+. Inhibition of TNKS1 leads to a decreased incorporation of NAD+ and consequently to a lower readout signal intensity. The concentration of a test compound which inhibits the enzyme activity by 50% (corresponds to half of the normed readout signal intensity) is reported as IC50.

Modified TNKS1 Assay 2

The potency of selected compounds according to the invention was assessed applying an modified in vitro inhibition assay. Here, the TNKS1 catalyzed NAD+-dependent ribosylation of the enzyme itself (auto-parsylation) was detected using [3H]-NAD+ as substrate and applying the scintillation proximity assay (SPA) method to detect tritium-labeled, parsylated TNKS1. The intensity of the readout signal is proportional to the incorporated [3H]-NAD+. Inhibition of TNKS1 leads to a decreased incorporation of [3H]-NAD+ and consequently to a lower readout signal intensity. The concentration of a test compound which inhibits the enzyme activity by 50% (corresponds to half of the normed readout signal intensity) is reported as IC50.
Protocol Auto-Parsylation Assay
The assay was conducted in a 96 well MTP format with the identical TNKS1 enzyme sample and NAD+ sample as in the histone ribosylation assay with the following modifications: TNKS1 enzyme sample was diluted with a modified assay buffer (50 mM MES pH 7.0, 1 mM DTT, 0.01% Triton X-100) to a final concentration of 6 nM TNKS1 and 10×NAD+ solution was diluted with the modified assay buffer (s. above) to a final 0.445×NAD+ solution doped with 100 Bq/ul [3H]-NAD+[Catalog #NET443H050UC, Perkin Elmer, Waltham, Mass., USA]. Substrate solution (10 ul) was incubated with different test compound concentrations (2.5 ul in 10% DMSO in modified assay buffer) or control (2.5 ul 10% DMSO in modified assay buffer only) and enzyme (10 ul) over night at room temperature. Incorporated tritium was measured after addition of 50 ul SPA beads (1 mg/ml) [Catalog #RPNQ0095 20 mg/ml, Perkin Elmer, Waltham, Mass., USA; diluted 1:10 with Dulbecco's phosphate buffered saline, PBS Catalog #D8537, Sigma-Aldrich, Steinheim, Germany] and detection of the photon emission with a beta count plate reader [Wallac MicroBeta®, Perkin Elmer, Waltham, Mass., USA].
Modified TNKS1 Assay 3
The potency of the compounds against human TNKS1 according to the invention was assessed using a commercially available biotin/streptavidin binding assay kits from BPS Bioscience, San Diego, USA (Catalog #80573 for TNKS1). The incorporation of a biotin-labeled NAD+ during the PAPR1 catalyzed ribosylation of a suitable protein substrate was detected using with a streptavidin-HRP coupled chemi-luminescent readout. The intensity of the readout signal is proportional to the incorporated NAD+. Inhibition of TNKS1 leads to a decreased incorporation of NAD+ and consequently to a lower readout signal intensity in the corresponding TNKS1 assays. The concentration of a test compound that inhibits the enzyme activity by 50% (corresponds to half of the normed readout signal intensity) is reported as IC50. The assay was conducted in a 96 well MTP format according to the manufacturer's protocol and using a BMG Pherastar MTP reader [BMG-Labtech, Offenburg, Germany].

6.2 TNKS2 Assays

TNKS2 Assay 1

The potency of the compounds according to the invention was assessed applying an in vitro inhibition assay. The TNKS2 catalyzed NAD+-dependent ribosylation of a suitable protein substrate was detected using a commercially available biotin/streptavidin binding based assay format [TNKS2 Histone Ribosylation Assay Kit (Biotin-labeled NAD+), Catalog #80572; BPS Bioscience, San Diego, USA]. Here, the incorporation of a biotin-labeled NAD+ during the TNKS2 catalyzed ribosylation reaction was detected with a streptavidin-HRP coupled chemi-luminescent readout. The intensity of the readout signal is proportional to the incorporated NAD+. Inhibition of TNKS2 leads to a decreased incorporation of NAD+ and consequently to a lower readout signal intensity. The concentration of a test compound which inhibits the enzyme activity by 50% (corresponds to half of the normed readout signal intensity) is reported as IC50.
Protocol
The assay was conducted in a 384 well MTP format according to the manufacturer's protocol [bpsbioscience.com/poly-adp-ribose-polymerase/assay-kit/tnks2-histone-ribosylation-assay-kit-biotin-labeled-nad-80572 referencing: Brown, J. A., Marala, R. B. J. Pharmacol. Toxicol. Methods 2002 47:137-41]. and using a BMG Pherastar MTP reader [BMG-Labtech, Offenburg, Germany].

6.3 PARP1 Assay

The potency of the compounds according to the invention was assessed using a commercially available biotin/streptavidin binding assay kits from BPS Bioscience, San Diego, USA (Catalog #80551). The incorporation of a biotin-labeled NAD+ during the PARP1 catalyzed ribosylation of a suitable protein substrate was detected using with a streptavidin-HRP coupled chemi-luminescent readout. The intensity of the readout signal is proportional to the incorporated NAD+. Inhibition of PARP1 leads to a decreased incorporation of NAD+ and consequently to a lower readout signal intensity. The concentration of a test compound that inhibits the enzyme activity by 50% (corresponds to half of the normed readout signal intensity) is reported as IC50.
Protocol
The assay was conducted in a 96 well MTP format according to the manufacturer's protocol (Catalog No. 80551) and using a BMG Pherastar MTP reader [BMG-Labtech, Offenburg, Germany].

7 CELLULAR ASSAYS
7.1 Measurement of the Inhibitory Activity of Selected Compounds on the Wildtype Wnt Signaling Cascade: HEK293 TOP/FOP Assay
In order to discover and characterize small molecules which inhibit the wildtype Wnt pathway, a cellular reporter assay was employed. The corresponding assay cell was generated by transfection of the mammalian cell line HEK293 (ATCC, #CRL-1573) with the Super TopFlash vector (Morin, Science 275, 1997, 1787-1790; Molenaar et al., Cell 86 (3), 1996, 391-399). The HEK293 cell line is cultivated at 37° C. and 5% CO2 in DMEM (Life Technologies, #41965-039), supplemented with 2 mM glutamine, 20 mM HEPES, 1.4 mM pyruvate, 0.15% Na-bicarbonate and 10% foetal bovine serum (GIBCO, #10270). Stable transfectants were generated by selection with 300 μg/ml Hygromycin.
In a parallel approach, HEK293 cells were cotransfected with the FOP control vector and pcDNA3. The FOP vector is identical to the TOP construct, but it contains instead of functional TCF elements a randomized, non-functional sequence. For this transfection a stable transfected cell line was generated as well, based on selection with Geneticin (1 mg/ml).
In preparation of the assay, the two cell lines were plated 24 hrs before beginning the test at 10000 cells per well in a 384 micro titre plate (MTP) in 30 μl growth medium. Before compound testing a dose response curve for the Wnt dependent luciferase expression was recorded by stimulating the assay cell line with human recombinant Wnt-3a (R&D, #5036-WN-010) at different concentrations for 16 hrs at 37° C. and 5% CO2 followed by subsequent luciferase measurement, to determine the Wnt-3a EC50 for the HEK293 TOP cell line on the day of testing. The recombinant human Wnt-3a was thereby applied between 2500 and 5 ng/ml in two-fold dilution steps.
Selective inhibitory activity for small molecules on the wildtype Wnt pathway was determined after parallel incubation of both (TOP and FOP) HEK293 reporter cell lines with a compound dilution series from 50 μM to 15 nM in steps of 3.16-fold dilutions in CAFTY buffer (130 mM sodium chloride, 5 mM potassium chloride, 20 mM HEPES, 1 mM magnesium chloride, 5 mM sodium bicarbonate, pH 7.4) containing 2 mM Ca2+ and 0.01% BSA.
The compounds were thereby serially prediluted in 100% DMSO and thereafter 50 fold into the CAFTY compound dilution buffer (described above). From this dilution 10 μl were added in combination with the EC50 concentration of recombinant Wnt3a to the cells in 30 μl growth medium and incubated for 16 hours at 37° C. and 5% CO2. Thereafter luciferase assay buffer (1:1 mixture of luciferase substrate buffer (20 mM Tricine, 2.67 mM magnesium sulfate, 0.1 mM EDTA, 4 mM DTT, 270 μM Coenzyme A, 470 μM Luciferin, 530 μM ATP, ph adjusted to pH 7.8 with a sufficient volume of 5M sodium hydroxide) and Triton buffer (30 ml Triton X-100, 115 ml glycerol, 308 mg Dithiothreitol, 4.45 g disodium hydrogen phosphate 2H2O, 3.03 g Tris.HCL, ad 1 l H2O, pH 7.8) was added in an equal volume to determine luciferase expression as a measure of Wnt signaling activity in a luminometer. The Wnt inhibitory activity was determined as IC50 of resulting dose response curves.

7.2 Axin Stabilization Assay

The in vitro and in vivo effect of Tankyrase inhibition on the stabilization of cellular Axin was assessed using Peggy Simple Western assay with size-based separation and immunodetection of Axin2. 5W403 cells (but not limited to) were seeded at 50000 cells per well in 96-well plates. After overnight incubation, cells were treated with testing compounds and vehicle at 37° C. for 24 hours. Thereafter, cells were washed with PBS and then lysed in 15 μL of lysis buffer (M-PER buffer, Thermo Scientific #78505) with complete proteinase and phosphatase inhibitors (Roche, #11836153001 and #04906837001). The lysates were centrifuged and the supernatants were harvested for analysis. Tumor xenografts from in vivo studies were homogenized in a 2 mL tubes of Precellys®24 (Bertin Technologies, Villeurbanne, France) following with centrifugation to obtain tumor lysates. Capillary electrophoresis-based Simple Western assays were carried out with Peggy SueTM NanoPro 1000 (ProteinSimple, California, USA). The protein amounts of Axin2 (but not limited to) were detected using anti-Axin2 antibody (Cell Signaling, Catalog #2151), quantified using the area under the curve, and normalized against GAPDH (anti-GAPDH, Zytomed Systems GmbH, Catalog #RGM2-6C5, Berlin, Germany).
7.3 Real-Time RT-PCR for Quantitative Analysis of Gene Transcription
Real-time RT-PCR using a TaqMan fluorogenic detection system is a simple and sensitive assay for quantitative analysis of gene transcription. The TaqMan fluorogenic detection system can monitor PCR in real time using a dual-labeled fluorogenic hybridization probe (TaqMan probe) and a polymerase with 5′-3′ exonuclease activity.
Cells from different cancer cell lines (as HCT116, but not limited to) were grown at 500-1000 cells/well in 384 well cell culture plates. For cell lysis the cell medium was carefully removed. The cells were washed carefully once with 50 μl/well PBS. Then 9.75 μl/well cell lysis buffer (50 mM Tris HCl pH 8.0, 40 mM sodium chloride, 1.5 mM magnesium chloride, 0.5% IGEPAL CA 630, 50 mM Guanidium thiocyanate) and 0.25 μl RNASeOUT (40 U/μl, Invitrogen, 10777-019)) per well were added. The plate was incubated for 5 min at room temperature. Then 30 μl DNAse/RNAse-free water per well was added and the lysates mixed. Isolation of total RNA from tumor tissues was conducted using InviTrape Spin Tissue RNA Mini Kit (#1062100300, STRATEC MOLECULAR).
For the One-Step RT-PCR 2 μl lysate (each) was transferred to a 384 well PCR plate. The PCR reaction was composed by 5 μl 2× One Step RT qPCR MasterMix Plus, 0.05 μl Euroscript RT/RNAse Inhibitor (50 U/μl, 20 U/μl) and 200 nM of the appropriate Primer/Hydrolysis Probe mix (primer sequences of forward, reverse and probe are given below for each analysed gene of interest or house keeping gene). 10 μl water were added per well. The plate was sealed with an adhesive optical film. The RT-PCR protocol was setup with 30 min 48° C., then 10 min 95° C. followed by 50 cycles of 15 sec 95° C./1 min 60° C. and a cooling step of 40° C. for 30 sec using a Lightcycler LS440 from Roche. Relative expression was calculated using CP values from the gene of interest (e.g. AXIN2, but not limited to) and a house keeping gene (L32).

8 IN VIVO EFFICACY IN XENOGRAFT MODELS
Subcutaneous xenograft models in immunocompromised mice were used to evaluate in vivo anti-tumor efficacy of the compounds.
8.1 Maximum Tolerable Dose (MTD) Studies
Prior to efficacy studies, the maximal tolerable dose (MTD) was determined by the following protocol: Female nude mice (NMRI (nu/nu), Taconic M&B A/S) received a defined oral dose of the test compound daily or bi-daily for 7 consecutive days followed by a 7 day observation period without dosing. Individual body weight and lethality were monitored daily.
The MTD is defined as the maximal applicable dose with a) no animal losing more than 10% body weight compared to initial body weight and b) no lethality during treatment phase.
8.2 In Vivo Efficacy Studies
To measure anti-tumor efficacy, the test compounds were analysed in xenograft models on mice. Test compounds were dosed orally at their respective MTD as well as at sub-MTD dosages. In case the MTD could not be determined in previous MTD studies, the compounds were dosed at a maximum daily dose of 200 mg/kg (applied either in one single dose or split in 2 doses at 100 mg/kg).
Compounds were primarily analyzed in an ovarian teratocarcinoma model (PA-1) and in various colorectal cancer models on female immunocompromised mice.
For this purpose, 1-5×106 tumor cells (suspended in 0.1 ml of 50% cell culture medium/50% Matrigel) were subcutaneously injected into the flank of each animal. Animals were randomized into treatment groups when tumors had reached an average area of 20-30 mm2 and treatment was started. Body weight and tumor area of each animal were measured 2-3 times weekly, depending on tumor growth. Studies were terminated, when animals in the control groups (receiving only compound vehicle solutions) or treatment groups reached tumor areas −150 mm2. At that time point, all groups in the study were terminated, tumors were isolated and weighed.
As primary parameter for anti-tumor efficacy the Treatment/Control (T/C) ratio of the final tumor weights were calculated (mean tumor weight of treatment group divided by mean tumor weight of vehicle group).
8.3 In Vivo Mode of Action Studies
To determine in vivo Mode of Action (MoA) of the test compounds, the same in vivo models as described under 8.2 were utilized. Tumor-bearing animals were treated for at least 3 days at MTD and also sub-MTD dosages. At study end, tumors were isolated and snap frozen in liquid N2. Total RNA and protein were isolated from tumor samples following standard protocols.
Wnt/β-catenin target gene expression and Axin2 protein abundance were measured by standard qRT-PCR and Western blotting methods (see 7.2 and 7.3).
