Definitions

  • the invention had the object of finding novel compounds having valuable properties, in particular those which can be used for the preparation of medicaments.
  • the present invention relates to tetrahydro-quinazoline derivatives which inhibit the activity of Tankyrases (TANKs) and poly(ADP-ribose)polymerase PARP-1.
  • TANKs Tankyrases
  • PARP-1 poly(ADP-ribose)polymerase PARP-1.
  • the compounds of this invention are therefore useful in treating diseases such as cancer, multiple sclerosis, cardiovascular diseases, central nervous system injury and different forms of inflammation.
  • the present invention also provides methods for preparing these compounds,
  • compositions comprising these compounds, and methods of treating diseases utilizing pharmaceutical compositions comprising these compounds.
  • the nuclear enzyme poly(ADP-ribose) polymerase-1 (PARP-1) is a member of the PARP enzyme family. This growing family of enzymes consist of PARPs such as, for example: PARP-1 , PARP-2, PARP-3 and Vault-PARP; and
  • Tankyrases such as, for example: TANK-1 and TANK-2.
  • PARP is also referred to as poly(adenosine 5'-diphospho-ribose) polymerase or PARS (poly(ADP-ribose) synthetase).
  • TANK-1 seems to be required for the polymerization of mitotic spindle- associated poly(ADP-ribose).
  • the poly(ADP-ribosyl)ation activity of TANK-1 might be crucial for the accurate formation and maintenance of spindle bipolarity.
  • PARP activity of TANK-1 has been shown to be required for normal telomere separation before anaphase. Interference with tankyrase PARP activity results in aberrant mitosis, which engenders a transient cell cycle arrest, probably due to spindle checkpoint activation, followed by cell death. Inhibition of tankyrases is therefore expected to have a cytotoxic effect on proliferating tumor cells (WO 2008/107478).
  • PARP inhibitors are described by M. Rouleau et al. in Nature Reviews, Volume 10, 293-301 in clinical cancer studies (Table 2, page 298).
  • PARP inhibitors enhance the cancer cell death primarily because they interfere with DNA repair on various levels. More recent studies have also demonstrated that PARP inhibitors inhibit angiogenesis, either by inhibiting growth factor expression, or by inhibiting growth factor-induced cellular proliferative responses. These findings might also have implications on the mode of PARP inhibitors' anticancer effects in vivo.
  • the Wnt pathway is a target for anti-cancer therapy.
  • a key feature of the Wnt pathway is the regulated proteolysis
  • the compound XAV939 inhibits growth of DLD-1- cancer cells. They found that XAV9393 blocked Wnt-stimulated accumulation of ⁇ -catenin by increasing the levels of the AXIN1 and AXIN2 proteins.
  • XAV939 regulates AXIN levels via inhibition of tankyrases 1 and 2 (TNKS1 and TNKS2), both of which are members of the poly(ADP-ribose) polymerase (PARP) protein family (S.J. Hsiao et al., Biochimie 90, 2008, 83-92).
  • PARP poly(ADP-ribose) polymerase
  • the present invention specifically relates to compounds of the formula I which inhibit Tankyrase 1 and 2, to compositions which comprise these compounds, and to processes for the use thereof for the treatment of TANK-induced diseases and complaints.
  • the compounds of the formula I can furthermore be used for the isolation and investigation of the activity or expression of TANKs. In addition, they are particularly suitable for use in diagnostic methods for diseases in connection with unregulated or disturbed TANK activity.
  • the host or patient can belong to any mammalian species, for example a primate species, particularly humans; rodents, including mice, rats and hamsters; rabbits; horses, cows, dogs, cats, etc. Animal models are of interest for experimental investigations, providing a model for treatment of human disease.
  • the susceptibility of a particular cell to treatment with the compounds according to the invention can be determined by in vitro tests.
  • a culture of the cell is combined with a compound according to the invention at various concentrations for a period of time which is sufficient to allow active agents such as anti IgM to induce a cellular response such as expression of a surface marker, usually between about one hour and one week.
  • In vitro testing can be carried out using cultivated cells from blood or from a biopsy sample. The amount of surface marker expressed are assessed by flow cytometry using specific antibodies recognising the marker.
  • the dose varies depending on the specific compound used, the specific disease, the patient status, etc.
  • a therapeutic dose is typically sufficient considerably to reduce the undesired cell population in the target tissue while the viability of the patient is maintained.
  • the treatment is generally continued until a considerable reduction has occurred, for example an at least about 50% reduction in the cell burden, and may be continued until essentially no more undesired cells are detected in the body.

Abstract

Description

TETRAHYDRO - QUINAZOLINONE DERIVATIVES AS TANK AND PARP INHIBITORS
BACKGROUND OF THE INVENTION
The invention had the object of finding novel compounds having valuable properties, in particular those which can be used for the preparation of medicaments.
The present invention relates to tetrahydro-quinazoline derivatives which inhibit the activity of Tankyrases (TANKs) and poly(ADP-ribose)polymerase PARP-1. The compounds of this invention are therefore useful in treating diseases such as cancer, multiple sclerosis, cardiovascular diseases, central nervous system injury and different forms of inflammation. The present invention also provides methods for preparing these compounds,
pharmaceutical compositions comprising these compounds, and methods of treating diseases utilizing pharmaceutical compositions comprising these compounds.
The nuclear enzyme poly(ADP-ribose) polymerase-1 (PARP-1) is a member of the PARP enzyme family. This growing family of enzymes consist of PARPs such as, for example: PARP-1 , PARP-2, PARP-3 and Vault-PARP; and
Tankyrases (TANKs), such as, for example: TANK-1 and TANK-2. PARP is also referred to as poly(adenosine 5'-diphospho-ribose) polymerase or PARS (poly(ADP-ribose) synthetase).
TANK-1 seems to be required for the polymerization of mitotic spindle- associated poly(ADP-ribose). The poly(ADP-ribosyl)ation activity of TANK-1 might be crucial for the accurate formation and maintenance of spindle bipolarity. Furthermore, PARP activity of TANK-1 has been shown to be required for normal telomere separation before anaphase. Interference with tankyrase PARP activity results in aberrant mitosis, which engenders a transient cell cycle arrest, probably due to spindle checkpoint activation, followed by cell death. Inhibition of tankyrases is therefore expected to have a cytotoxic effect on proliferating tumor cells (WO 2008/107478). PARP inhibitors are described by M. Rouleau et al. in Nature Reviews, Volume 10, 293-301 in clinical cancer studies (Table 2, page 298).
According to a review by Horvath and Szabo (Drug News Perspect 20(3), April 2007, 171-181) most recent studies demonstrated that PARP inhibitors enhance the cancer cell death primarily because they interfere with DNA repair on various levels. More recent studies have also demonstrated that PARP inhibitors inhibit angiogenesis, either by inhibiting growth factor expression, or by inhibiting growth factor-induced cellular proliferative responses. These findings might also have implications on the mode of PARP inhibitors' anticancer effects in vivo.
Also a study by Tentori et al. (Eur. J. Cancer, 2007, 43 (14) 2124-2133) shows that PARP inhibitors abrogate VEGF or placental growth factor-induced migration and prevent formation of tubule-like networks in cell-based systems, and impair angiogenesis in vivo. The study also demonstrates that growth factor-induced angiogenesis is deficient in PARP-1 knock-out mice. The results of the study provide evidence for targetting PARP for anti- angiogenesis, adding novel therapeutic implications to the use of PARP inhibitors in cancer treatment.
Defects in conserved signaling pathways are well known to play key roles in the origins and behavior of essentially all cancers (E.A.Fearon, Cancer Cell, Vol. 16, Issue 5, 2009, 366-368). The Wnt pathway is a target for anti-cancer therapy. A key feature of the Wnt pathway is the regulated proteolysis
(degradation) of β-catenin by the β-catenin destruction complex. Proteins like WTX, APC or Axin are involved in the degradation process. A proper degradation of β-catenin is important to avoid an inappropriate activation of the Wnt pathway which has been observed in many cancers. Tankyrases inhibit activity of Axin and hence inhibit the degradation of β-catenin.
Consequently, tankyrase inhibitors increase degradation of β-catenin. A recent paper in the journal Nature not only offers important new insights into proteins regulating Wnt signaling but also further supports the approach to antagonize β-catenin levels and localization via small molecules (Huang et al., 2009;
Nature, Vol 461 , 614-620). The compound XAV939 inhibits growth of DLD-1- cancer cells. They found that XAV9393 blocked Wnt-stimulated accumulation of β-catenin by increasing the levels of the AXIN1 and AXIN2 proteins.
Subsequent work by the authors established that XAV939 regulates AXIN levels via inhibition of tankyrases 1 and 2 (TNKS1 and TNKS2), both of which are members of the poly(ADP-ribose) polymerase (PARP) protein family (S.J. Hsiao et al., Biochimie 90, 2008, 83-92).
It has been found that the compounds according to the invention and salts thereof have very valuable pharmacological properties while being well tolerated.
The present invention specifically relates to compounds of the formula I which inhibit Tankyrase 1 and 2, to compositions which comprise these compounds, and to processes for the use thereof for the treatment of TANK-induced diseases and complaints.
The compounds of the formula I can furthermore be used for the isolation and investigation of the activity or expression of TANKs. In addition, they are particularly suitable for use in diagnostic methods for diseases in connection with unregulated or disturbed TANK activity.
The host or patient can belong to any mammalian species, for example a primate species, particularly humans; rodents, including mice, rats and hamsters; rabbits; horses, cows, dogs, cats, etc. Animal models are of interest for experimental investigations, providing a model for treatment of human disease.
The susceptibility of a particular cell to treatment with the compounds according to the invention can be determined by in vitro tests. Typically, a culture of the cell is combined with a compound according to the invention at various concentrations for a period of time which is sufficient to allow active agents such as anti IgM to induce a cellular response such as expression of a surface marker, usually between about one hour and one week. In vitro testing can be carried out using cultivated cells from blood or from a biopsy sample. The amount of surface marker expressed are assessed by flow cytometry using specific antibodies recognising the marker.
The dose varies depending on the specific compound used, the specific disease, the patient status, etc. A therapeutic dose is typically sufficient considerably to reduce the undesired cell population in the target tissue while the viability of the patient is maintained. The treatment is generally continued until a considerable reduction has occurred, for example an at least about 50% reduction in the cell burden, and may be continued until essentially no more undesired cells are detected in the body.

Moreover, the invention relates to pharmaceutically acceptable derivatives of compounds of formula I.
The term solvates of the compounds is taken to mean adductions of inert solvent molecules onto the compounds which form owing to their mutual attractive force. Solvates are, for example, mono- or dihydrates or
alkoxides.
It is understood, that the invention also relates to the solvates of the salts. The term pharmaceutically acceptable derivatives is taken to mean, for example, the salts of the compounds according to the invention and also so-called prodrug compounds.

Examples of prodrugs include, but are not limited to, derivatives and metabolites of a compound of formula I that include biohydrolyzable moieties such as biohydrolyzable amides, biohydrolyzable esters, biohydrolyzable carbamates, biohydrolyzable carbonates, biohydrolyzable ureides, and biohydrolyzable phosphate analogues. In certain embodiments, prodrugs of compounds with carboxyl functional groups are the lower alky! esters of the carboxylic acid. The carboxylate esters are conveniently formed by esterifying any of the carboxylic acid moieties present on the molecule. Prodrugs can typically be prepared using well- known methods, such as those described by Burger 's Medicinal Chemistry and Drug Discovery 6th ed. (Donald J. Abraham ed., 2001, Wiley) and Design and Application of Prodrugs (H.Bundgaard ed., 1985, Harwood Academic Publishers Gmfh).

The compounds of the formula I and also the starting materials for their preparation are, in addition, prepared by methods known per se, as described in the literature (for example in the standard works, such as Houben-Weyl, Methoden der organischen Chemie [Methods of Organic Chemistry], Georg-Thieme-Verlag, Stuttgart), to be precise under reaction conditions which are known and suitable for the said reactions. Use can also be made here of variants known per se which are not mentioned here in greater detail.
The starting compounds of the formulae II and III are generally known. If they are novel, however, they can be prepared by methods known per se.
Compounds of the formula I can preferably be obtained by reacting in a first step the compound of the formula II with a compound of the formula III.
Depending on the conditions used, the reaction time is between a few minutes and 14 days, the reaction temperature is between about -10° and 180°, normally between 30° and 170°, in particular between about 60° and about 160°.
Examples of suitable inert solvents are hydrocarbons, such as hexane, petroleum ether, benzene, toluene or xylene; chlorinated hydrocarbons, such as trichloroethylene, 1 ,2-dichloroethane, carbon tetrachloride, chloroform or dichloromethane; alcohols, such as methanol, ethanol, isopropa- nol, n-propanol, n-butanol or tert-butanol; ethers, such as diethyl ether, diisopropyl ether, tetrahydrofuran (THF) or dioxane; glycol ethers, such as ethylene glycol monomethyl or monoethyl ether, ethylene glycol dimethyl ether (diglyme); ketones, such as acetone or butanone; amides, such as acetamide, dimethylacetamide or dimethylformamide (DMF); nitriles, such as acetonitrile; sulfoxides, such as dimethyl sulfoxide (DMSO); carbon disulfide; carboxylic acids, such as formic acid or acetic acid; nitro compounds, such as nitromethane or nitrobenzene; esters, such as ethyl ace- tate, or mixtures of the said solvents.
Particular preference is given to isoamylalcohol.
Free amino groups can furthermore be acylated in a conventional manner using an acid chloride or anhydride or alkylated using an unsubstituted or substituted alkyl halide, advantageously in an inert solvent, such as di- chloromethane or THF, and/or in the presence of a base, such as triethyl- amine or pyridine, at temperatures between -60 and +30°.
Pharmaceutical salts and other forms
The said compounds according to the invention can be used in their final non-salt form. On the other hand, the present invention also encompasses the use of these compounds in the form of their pharmaceutically accept- able salts, which can be derived from various organic and inorganic acids and bases by procedures known in the art. Pharmaceutically acceptable salt forms of the compounds of the formula I are for the most part prepared by conventional methods. If the compound of the formula I contains a car- boxyl group, one of its suitable salts can be formed by reacting the compound with a suitable base to give the corresponding base-addition salt. Such bases are, for example, alkali metal hydroxides, including potassium hydroxide, sodium hydroxide and lithium hydroxide; alkaline earth metal hydroxides, such as barium hydroxide and calcium hydroxide; alkali metal alkoxides, for example potassium ethoxide and sodium propoxide; and various organic bases, such as piperidine, diethanolamine and N-methyl- glutamine. The aluminium salts of the compounds of the formula I are likewise included. In the case of certain compounds of the formula I, acid- addition salts can be formed by treating these compounds with pharmaceutically acceptable organic and inorganic acids, for example hydrogen halides, such as hydrogen chloride, hydrogen bromide or hydrogen iodide, other mineral acids and corresponding salts thereof, such as sulfate, nitrate or phosphate and the like, and alkyl- and monoarylsulfonates, such as ethanesulfonate, toluenesulfonate and benzenesulfonate, and other organic acids and corresponding salts thereof, such as acetate, trifluoro- acetate, tartrate, maleate, succinate, citrate, benzoate, salicylate, ascor- bate and the like. Accordingly, pharmaceutically acceptable acid-addition salts of the compounds of the formula I include the following: acetate, adi- pate, alginate, arginate, aspartate, benzoate, benzenesulfonate (besylate), bisulfate, bisulfite, bromide, butyrate, camphorate, camphorsulfonate, caprylate, chloride, chlorobenzoate, citrate, cyclopentanepropionate, diglu- conate, dihydrogenphosphate, dinitrobenzoate, dodecylsulfate, ethanesulfonate, fumarate, galacterate (from mucic acid), galacturonate, gluco- heptanoate, gluconate, glutamate, glycerophosphate, hemisuccinate, hemisulfate, heptanoate, hexanoate, hippurate, hydrochloride, hydro- bromide, hydroiodide, 2-hydroxyethanesulfonate, iodide, isethionate, iso- butyrate, lactate, lactobionate, malate, maleate, malonate, mandelate, metaphosphate, methanesulfonate, methylbenzoate, monohydrogenphos- phate, 2-naphthalenesulfonate, nicotinate, nitrate, oxalate, oleate, palmo- ate, pectinate, persulfate, phenylacetate, 3-phenylpropionate, phosphate, phosphonate, phthalate, but this does not represent a restriction.
Furthermore, the base salts of the compounds according to the invention include aluminium, ammonium, calcium, copper, iron(lll), iron(ll), lithium, magnesium, manganese(lll), manganese(ll), potassium, sodium and zinc salts, but this is not intended to represent a restriction. Of the above-mentioned salts, preference is given to ammonium; the alkali metal salts sodium and potassium, and the alkaline earth metal salts calcium and magnesium. Salts of the compounds of the formula I which are derived from pharmaceutically acceptable organic non-toxic bases include salts of primary, secondary and tertiary amines, substituted amines, also including naturally occurring substituted amines, cyclic amines, and basic ion ex- changer resins, for example arginine, betaine, caffeine, chloroprocaine, choline, Ν,Ν'-dibenzylethylenediamine (benzathine), dicyclohexylamine, diethanolamine, diethylamine, 2-diethylaminoethanol, 2-dimethylamino- ethanol, ethanolamine, ethylenediamine, N-ethylmorpholine, N-ethyl- piperidine, glucamine, glucosamine, histidine, hydrabamine, isopropyl- amine, lidocaine, lysine, meglumine, N-methyl-D-glucamine, morpholine, piperazine, piperidine, polyamine resins, procaine, purines, theobromine, triethanolamine, triethylamine, trimethylamine, tripropylamine and tris- (hydroxymethyl)methylamine (tromethamine), but this is not intended to represent a restriction.
Compounds of the present invention which contain basic nitrogen-containing groups can be quaternised using agents such as (Ci-C4)alkyl halides, for example methyl, ethyl, isopropyl and tert-butyl chloride, bromide and iodide; di(Ci-C4)alkyl sulfates, for example dimethyl, diethyl and diamyl sulfate; (Cio-Ci8)alkyl halides, for example decyl, dodecyl, lauryl, myristyl and stearyl chloride, bromide and iodide; and aryl(Ci-C4)alkyl halides, for example benzyl chloride and phenethyl bromide. Both water- and oil-soluble compounds according to the invention can be prepared using such salts.
The above-mentioned pharmaceutical salts which are preferred include acetate, trifluoroacetate, besylate, citrate, fumarate, gluconate, hemisucci- nate, hippurate, hydrochloride, hydrobromide, isethionate, mandelate, meglumine, nitrate, oleate, phosphonate, pivalate, sodium phosphate, stea- rate, sulfate, subsalicylate, tartrate, thiomalate, tosylate and tromethamine, but this is not intended to represent a restriction.
Particular preference is given to hydrochloride, dihydrochloride, hydrobromide, maleate, mesylate, phosphate, sulfate and succinate. The acid-addition salts of basic compounds of the formula I are prepared by bringing the free base form into contact with a sufficient amount of the desired acid, causing the formation of the salt in a conventional manner. The free base can be regenerated by bringing the salt form into contact with a base and isolating the free base in a conventional manner. The free base forms differ in a certain respect from the corresponding salt forms thereof with respect to certain physical properties, such as solubility in polar solvents; for the purposes of the invention, however, the salts otherwise correspond to the respective free base forms thereof.
As mentioned, the pharmaceutically acceptable base-addition salts of the compounds of the formula I are formed with metals or amines, such as alkali metals and alkaline earth metals or organic amines. Preferred metals are sodium, potassium, magnesium and calcium. Preferred organic amines are Ν,Ν'-dibenzylethylenediamine, chloroprocaine, choline, di- ethanolamine, ethylenediamine, N-methyl-D-glucamine and procaine.
The base-addition salts of acidic compounds according to the invention are prepared by bringing the free acid form into contact with a sufficient amount of the desired base, causing the formation of the salt in a conventional manner. The free acid can be regenerated by bringing the salt form into contact with an acid and isolating the free acid in a conventional manner. The free acid forms differ in a certain respect from the corresponding salt forms thereof with respect to certain physical properties, such as solubility in polar solvents; for the purposes of the invention, however, the salts otherwise correspond to the respective free acid forms thereof.
If a compound according to the invention contains more than one group which is capable of forming pharmaceutically acceptable salts of this type, the invention also encompasses multiple salts. Typical multiple salt forms include, for example, bitartrate, diacetate, difumarate, dimeglumine, di- phosphate, disodium and trihydrochloride, but this is not intended to represent a restriction.
With regard to that stated above, it can be seen that the expression "phar- maceutically acceptable salt" in the present connection is taken to mean an active ingredient which comprises a compound of the formula I in the form of one of its salts, in particular if this salt form imparts improved pharmacokinetic properties on the active ingredient compared with the free form of the active ingredient or any other salt form of the active ingredient used earlier. The pharmaceutically acceptable salt form of the active ingredient can also provide this active ingredient for the first time with a desired pharmacokinetic property which it did not have earlier and can even have a positive influence on the pharmacodynamics of this active ingredient with respect to its therapeutic efficacy in the body.
Isotopes
There is furthermore intended that a compound of the formula I includes isotope-labelled forms thereof. An isotope-labelled form of a compound of the formula I is identical to this compound apart from the fact that one or more atoms of the compound have been replaced by an atom or atoms having an atomic mass or mass number which differs from the atomic mass or mass number of the atom which usually occurs naturally.
Exam-pies of isotopes which are readily commercially available and which can be incorporated into a compound of the formula I by well-known methods include isotopes of hydrogen, carbon, nitrogen, oxygen, phos-phorus, fluo-rine and chlorine, for example 2H, 3H, 13C, 1 C, 15N, 180, 17Q 3i p 32p 35S ιβρ and 36Q| respective|y A compound of the formula I, a prodrug, thereof or a pharmaceutically acceptable salt of either which contains one or more of the above-mentioned isotopes and/or other iso-topes of other atoms is intended to be part of the present invention. An isotope-labelled compound of the formula I can be used in a number of beneficial ways. For example, an isotope-labelled compound of the formula I into which, for example, a radioisotope, such as 3H or 14C, has been incorporated is suitable for medicament and/or substrate tissue distribution assays. These radioisotopes, i.e. tritium (3H) and carbon-14 (14C), are particularly preferred owing to simple preparation and excellent detectability. Incor-po-ra-tion of heavier isotopes, for example deuterium (2H), into a compound of the formula I has therapeutic advantages owing to the higher metabolic stability of this isotope-labelled compound. Higher metabolic stability translates directly into an increased in vivo half-life or
10 lower dosages, which under most circumstances would represent a
preferred embodi-ment of the present invention. An isotope-labelled compound of the formula I can usually be prepared by carrying out the procedures dis-closed in the synthesis schemes and the related
^ description, in the example part and in the preparation part in the present text, replacing a non-isotope-labelled reactant by a readily available isotope-labelled reactant.
Deuterium (2H) can also be incorporated into a compound of the formula I
20
for the purpose in order to manipulate the oxidative metabolism of the compound by way of the primary kinetic isotope effect. The primary kinetic isotope effect is a change of the rate for a chemical reaction that results from exchange of isotopic nuclei, which in turn is caused by the change in
25 ground state energies necessary for covalent bond formation after this isotopic exchange. Exchange of a heavier isotope usually results in a lowering of the ground state energy for a chemical bond and thus cause a reduction in the rate in rate-limiting bond breakage. If the bond breakage
2Q occurs in or in the vicinity of a saddle-point region along the coordinate of a multi-product reaction, the product distribution ratios can be altered substantially. For explanation: if deuterium is bonded to a carbon atom at a non-exchangeable position, rate differences of kivi/ko = 2-7 are typical. If this rate difference is successfully applied to a corn-pound of the formula I
35
that is susceptible to oxidation, the profile of this compound in vivo can be drastically modified and result in improved pharmacokinetic properties. When discovering and developing therapeutic agents, the person skilled in the art attempts to optimise pharmacokinetic parameters while retaining desirable in vitro properties. It is reasonable to assume that many corn-pounds with poor pharmacokinetic profiles are susceptible to oxidative metabolism. In vitro liver microsomal assays currently available provide valuable information on the course of oxidative metabolism of this type, which in turn permits the rational design of deuterated compounds of the formula I with improved stability through resistance to such oxidative meta-bolism. Significant improvements in the pharmacokinetic profiles of compounds of the formula I are thereby obtained, and can be expressed quantitatively in terms of increases in the in vivo half-life (t/2),
concen-tra-tion at maximum therapeutic effect (Cmax), area under the dose response curve (AUC), and F; and in terms of reduced clearance, dose and materi-als costs.
The following is intended to illustrate the above: a compound of the formula I which has multiple potential sites of attack for oxidative
metabolism, for example benzylic hydrogen atoms and hydrogen atoms bonded to a nitrogen atom, is prepared as a series of analogues in which various combinations of hydrogen atoms are replaced by deuterium atoms, so that some, most or all of these hydrogen atoms have been replaced by deuterium atoms. Half-life determinations enable favourable and accurate determination of the extent of the extent to which the improve-ment in resistance to oxidative metabolism has improved. In this way, it is deter-mined that the half-life of the parent compound can be extended by up to 100% as the result of deuterium-hydrogen exchange of this type.
Deuterium-hydrogen exchange in a compound of the formula I can also be used to achieve a favourable modification of the metabolite spectrum of the starting compound in order to diminish or eliminate undesired toxic metabolites. For example, if a toxic metabolite arises through oxidative carbon-hydrogen (C-H) bond cleavage, it can reasonably be assumed that the deuterated analogue will greatly diminish or eliminate production of the unwanted metabolite, even if the particular oxidation is not a rate- determining step. Further information on the state of the art with respect to deuterium-hydrogen exchange may be found, for example in Hanzlik et al., J. Org. Chem. 55, 3992-3997, 1990, Reider et al., J. Org. Chem. 52, 3326- 3334, 1987, Foster, Adv. Drug Res. 14, 1-40, 1985, Gillette et al,
Biochemistry 33(10) 2927-2937, 1994, and Jarman et al. Carcinogenesis 16(4), 683-688, 1993.
The invention furthermore relates to medicaments comprising at least one compound of the formula I and/or pharmaceutically acceptable derivatives, solvates and stereoisomers thereof, including mixtures thereof in all ratios, and optionally excipients and/or adjuvants.
Pharmaceutical formulations can be administered in the form of dosage units which comprise a predetermined amount of active ingredient per dosage unit. Such a unit can comprise, for example, 0.5 mg to 1 g, preferably 1 mg to 700 mg, particularly preferably 5 mg to 100 mg, of a compound according to the invention, depending on the condition treated, the method of administration and the age, weight and condition of the patient, or pharmaceutical formulations can be administered in the form of dosage units which comprise a predetermined amount of active ingredient per dosage unit. Preferred dosage unit formulations are those which comprise a daily dose or part-dose, as indicated above, or a corresponding fraction thereof of an active ingredient. Furthermore, pharmaceutical formulations of this type can be prepared using a process which is generally known in the pharmaceutical art. Pharmaceutical formulations can be adapted for administration via any desired suitable method, for example by oral (including buccal or sublingual), rectal, nasal, topical (including buccal, sublingual or transdermal), vaginal or parenteral (including subcutaneous, intramuscular, intravenous or intradermal) methods. Such formulations can be prepared using all processes known in the pharmaceutical art by, for example, combining the active ingredient with the excipient(s) or adjuvant(s).
Pharmaceutical formulations adapted for oral administration can be administered as separate units, such as, for example, capsules or tablets; powders or granules; solutions or suspensions in aqueous or non-aqueous liquids; edible foams or foam foods; or oil-in-water liquid emulsions or water-in-oil liquid emulsions.
Thus, for example, in the case of oral administration in the form of a tablet or capsule, the active-ingredient component can be combined with an oral, non-toxic and pharmaceutically acceptable inert excipient, such as, for example, ethanol, glycerol, water and the like. Powders are prepared by comminuting the compound to a suitable fine size and mixing it with a pharmaceutical excipient comminuted in a similar manner, such as, for example, an edible carbohydrate, such as, for example, starch or mannitol. A flavour, preservative, dispersant and dye may likewise be present.
Capsules are produced by preparing a powder mixture as described above and filling shaped gelatine shells therewith. Glidants and lubricants, such as, for example, highly disperse silicic acid, talc, magnesium stearate, calcium stearate or polyethylene glycol in solid form, can be added to the powder mixture before the filling operation. A disintegrant or solubiliser, such as, for example, agar-agar, calcium carbonate or sodium carbonate, may likewise be added in order to improve the availability of the medicament after the capsule has been taken. ln addition, if desired or necessary, suitable binders, lubricants and disin- tegrants as well as dyes can likewise be incorporated into the mixture. Suitable binders include starch, gelatine, natural sugars, such as, for example, glucose or beta-lactose, sweeteners made from maize, natural and synthetic rubber, such as, for example, acacia, tragacanth or sodium alginate, carboxymethylcellulose, polyethylene glycol, waxes, and the like. The lubricants used in these dosage forms include sodium oleate, sodium stearate, magnesium stearate, sodium benzoate, sodium acetate, sodium
10 chloride and the like. The disintegrants include, without being restricted thereto, starch, methylcellulose, agar, bentonite, xanthan gum and the like. The tablets are formulated by, for example, preparing a powder mixture, granulating or dry-pressing the mixture, adding a lubricant and a disinteg-
^ 5 rant and pressing the entire mixture to give tablets. A powder mixture is prepared by mixing the compound comminuted in a suitable manner with a diluent or a base, as described above, and optionally with a binder, such as, for example, carboxymethylcellulose, an alginate, gelatine or polyvinylpyrrolidone, a dissolution retardant, such as, for example, paraffin, an ab-
20
sorption accelerator, such as, for example, a quaternary salt, and/or an absorbant, such as, for example, bentonite, kaolin or dicalcium phosphate. The powder mixture can be granulated by wetting it with a binder, such as, for example, syrup, starch paste, acadia mucilage or solutions of cellulose
25 or polymer materials and pressing it through a sieve. As an alternative to granulation, the powder mixture can be run through a tabletting machine, giving lumps of non-uniform shape, which are broken up to form granules. The granules can be lubricated by addition of stearic acid, a stearate salt,
2Q talc or mineral oil in order to prevent sticking to the tablet casting moulds.
The lubricated mixture is then pressed to give tablets. The compounds according to the invention can also be combined with a free-flowing inert excipient and then pressed directly to give tablets without carrying out the granulation or dry-pressing steps. A transparent or opaque protective layer
35
consisting of a shellac sealing layer, a layer of sugar or polymer material and a gloss layer of wax may be present. Dyes can be added to these coatings in order to be able to differentiate between different dosage units.
Oral liquids, such as, for example, solution, syrups and elixirs, can be pre- pared in the form of dosage units so that a given quantity comprises a pre- specified amount of the compound. Syrups can be prepared by dissolving the compound in an aqueous solution with a suitable flavour, while elixirs are prepared using a non-toxic alcoholic vehicle. Suspensions can be for-
10 mulated by dispersion of the compound in a non-toxic vehicle. Solubilisers and emulsifiers, such as, for example, ethoxylated isostearyl alcohols and polyoxyethylene sorbitol ethers, preservatives, flavour additives, such as, for example, peppermint oil or natural sweeteners or saccharin, or other
^ artificial sweeteners and the like, can likewise be added.
The dosage unit formulations for oral administration can, if desired, be encapsulated in microcapsules. The formulation can also be prepared in such a way that the release is extended or retarded, such as, for example,
20
by coating or embedding of particulate material in polymers, wax and the like.
The compounds of the formula I and salts, solvates and physiologically 25 functional derivatives thereof can also be administered in the form of liposome delivery systems, such as, for example, small unilamellar vesicles, large unilamellar vesicles and multilamellar vesicles. Liposomes can be formed from various phospholipids, such as, for example, cholesterol, 2Q stearylamine or phosphatidylcholines.
The compounds of the formula I and the salts, solvates and physiologically functional derivatives thereof can also be delivered using monoclonal antibodies as individual carriers to which the compound molecules are cou-
35
pled. The compounds can also be coupled to soluble polymers as targeted medicament carriers. Such polymers may encompass polyvinylpyrrolidone, pyran copolymer, polyhydroxypropylmethacrylamidophenol, polyhydroxy- ethylaspartamidophenol or polyethylene oxide polylysine, substituted by palmitoyl radicals. The compounds may furthermore be coupled to a class of biodegradable polymers which are suitable for achieving controlled release of a medicament, for example polylactic acid, poly-epsilon-capro- lactone, polyhydroxybutyric acid, polyorthoesters, polyacetals, polydihy- droxypyrans, polycyanoacrylates and crosslinked or amphipathic block copolymers of hydrogels.
Pharmaceutical formulations adapted for transdermal administration can be administered as independent plasters for extended, close contact with the epidermis of the recipient. Thus, for example, the active ingredient can be delivered from the plaster by iontophoresis, as described in general terms in Pharmaceutical Research, 3(6), 318 (1986).
Pharmaceutical compounds adapted for topical administration can be formulated as ointments, creams, suspensions, lotions, powders, solutions, pastes, gels, sprays, aerosols or oils.
For the treatment of the eye or other external tissue, for example mouth and skin, the formulations are preferably applied as topical ointment or cream. In the case of formulation to give an ointment, the active ingredient can be employed either with a paraffinic or a water-miscible cream base. Alternatively, the active ingredient can be formulated to give a cream with an oil-in-water cream base or a water-in-oil base.
Pharmaceutical formulations adapted for topical application to the eye include eye drops, in which the active ingredient is dissolved or suspended in a suitable carrier, in particular an aqueous solvent.
Pharmaceutical formulations adapted for topical application in the mouth encompass lozenges, pastilles and mouthwashes. Pharmaceutical formulations adapted for rectal administration can be administered in the form of suppositories or enemas.
Pharmaceutical formulations adapted for nasal administration in which the carrier substance is a solid comprise a coarse powder having a particle size, for example, in the range 20-500 microns, which is administered in the manner in which snuff is taken, i.e. by rapid inhalation via the nasal passages from a container containing the powder held close to the nose. Suitable formulations for administration as nasal spray or nose drops with a liquid as carrier substance encompass active-ingredient solutions in water or oil.
Pharmaceutical formulations adapted for administration by inhalation encompass finely particulate dusts or mists, which can be generated by various types of pressurised dispensers with aerosols, nebulisers or insufflators.
Pharmaceutical formulations adapted for vaginal administration can be administered as pessaries, tampons, creams, gels, pastes, foams or spray formulations.
Pharmaceutical formulations adapted for parenteral administration include aqueous and non-aqueous sterile injection solutions comprising antioxidants, buffers, bacteriostatics and solutes, by means of which the formula- tion is rendered isotonic with the blood of the recipient to be treated; and aqueous and non-aqueous sterile suspensions, which may comprise suspension media and thickeners. The formulations can be administered in single-dose or multidose containers, for example sealed ampoules and vials, and stored in freeze-dried (lyophilised) state, so that only the addition of the sterile carrier liquid, for example water for injection purposes, immediately before use is necessary. Injection solutions and suspensions pre- pared in accordance with the recipe can be prepared from sterile powders, granules and tablets.
It goes without saying that, in addition to the above particularly mentioned constituents, the formulations may also comprise other agents usual in the art with respect to the particular type of formulation; thus, for example, formulations which are suitable for oral administration may comprise flavours. A therapeutically effective amount of a compound of the formula I depends on a number of factors, including, for example, the age and weight of the animal, the precise condition that requires treatment, and its severity, the nature of the formulation and the method of administration, and is ultimate- ly determined by the treating doctor or vet. However, an effective amount of a compound according to the invention is generally in the range from 0.1 to 100 mg/kg of body weight of the recipient (mammal) per day and particularly typically in the range from 1 to 10 mg/kg of body weight per day. Thus, the actual amount per day for an adult mammal weighing 70 kg is usually between 70 and 700 mg, where this amount can be administered as a single dose per day or usually in a series of part-doses (such as, for example, two, three, four, five or six) per day, so that the total daily dose is the same. An effective amount of a salt or solvate or of a physiologically functional derivative thereof can be determined as the fraction of the effective amount of the compound according to the invention perse. It can be assumed that similar doses are suitable for the treatment of other conditions mentioned above.
A combined treatment of this type can be achieved with the aid of simultaneous, consecutive or separate dispensing of the individual components of the treatment. Combination products of this type employ the compounds according to the invention. The invention furthermore relates to medicaments comprising at least one compound of the formula I and/or pharmaceutically acceptable salts, solvates and stereoisomers thereof, including mixtures thereof in all ratios, and at least one further medicament active ingredient.
The invention also relates to a set (kit) consisting of separate packs of
(a) an effective amount of a compound of the formula I and/or pharmaceutically acceptable salts, solvates and stereoisomers thereof, in- eluding mixtures thereof in all ratios,
and
(b) an effective amount of a further medicament active ingredient.
The set comprises suitable containers, such as boxes, individual bottles, bags or ampoules. The set may, for example, comprise separate ampoules, each containing an effective amount of a compound of the formula I and/or pharmaceutically acceptable salts, solvates and stereoisomers thereof, including mixtures thereof in all ratios,
and an effective amount of a further medicament active ingredient in dissolved or lyophilised form.
"Treating" as used herein, means an alleviation, in whole or in part, of symptoms associated with a disorder or disease, or slowing, or halting of further progression or worsening of those symptoms, or prevention or prophylaxis of the disease or disorder in a subject at risk for developing the disease or disorder.
The term "effective amount" in connection with a compound of formula (I) can mean an amount capable of alleviating, in whole or in part, symptoms associated with a disorder or disease, or slowing or halting further progression or worsening of those symptoms, or preventing or providing prophylaxis for the disease or disorder in a subject having or at risk for developing a disease disclosed herein, such as inflammatory conditions, immunological conditions, cancer or metabolic conditions.

Biochemical activity testing of Tankyrase 1 and 2: Autoparsylation assay
The autoparsylation assay was run in two steps: the enzymatic reaction in which GST-tagged Tankyrase-1, resp Tankyrase-2 transferred biotinylated ADP-ribose to itself from biotinylated NAD as co-substrate and the detection reaction where a time resolved FRET between cryptate labelled anti-GST bound to the GST tag of the enzyme and Xlent® labelled- streptavidin bound the biotin-parsylation residue was analysed. The autoparsylation activity was detectable directly via the increase in HTRF signal.
The autoparsylation assay was performed as 384-well HTRF® (Cisbio, Codolet, France) assay format in Greiner low volume nb 384-well microtiter plates and was used for high throughput screen. 250 nM GST-tagged Tankyrase-1 (1023-1327 aa), respectively about 250 nM GST-tagged Tankyrase-2 (873-1166 aa) and 5 μΜ bio-NAD (Biolog, Life science Inst., Bremen, Germany) as co-substrate were incubated in a total volume of 5 μΙ (50 mM HEPES, 4 mM Mg-chloride, 0.05 % Pluronic F-68, 1.4 mM DTT, 0.5 % DMSO, pH 7.7) in the absence or presence of the test compound (10 dilution concentrations) for 90 min at 30°C. The reaction was stopped by the addition of 1 μΙ 50 mM EDTA solution. 2 μΙ of the detection solution (1.6 μΜ SA-Xlent® (Cisbio, Codolet, France), 7.4 nM Anti-GST-K® (Eu- labelled anti-GST, Cisbio, Codolet, France) in 50 mM HEPES, 800 mM KF, 0.1 % BSA, 20 mM EDTA, 0.1 % CHAPS, pH 7.0) were added. After 1h incubation at room temperature the HTRF was measured with an Envision multimode reader (Perkin Elmer LAS Germany GmbH) at excitation wavelength 340 nm (laser mode) and emission wavelengths 615 nm and 665 nm. The ratio of the emission signals was determined. The full value used was the inhibitor-free reaction. The pharmacological zero value used was XAV-939 (Tocris) in a final concentration of 5 μΜ. The inhibitory values (IC50) were determined using either the program Symyx Assay Explorer® or Condosseo® from GeneData.
Measurement of cellular inhibition of tankyrase
Since Tankyrases have been described to modulate cellular level of Axin2 (Huang et al., 2009; Nature) the increase of Axin2 level is used as read-out for determination of cellular inhibition of Tankyrases in a Luminex based assay.
Cells of the colon carcinoma cell line DLD1 are plated in 96 well plates with 1.5x104 cells per well. Next day, cells are treated with a serial-dilution of test compound in seven steps as triplicates with a final DMSO concentration of 0.3%. After 24 hours, cells are lysed in lysis buffer (20mM Tris/HCI pH 8.0, 150mM NaCI, 1% NP40, 10% Glycerol) and lysates are cleared by centrifugation through a 96 well filter plate (0.65μιη). Axin2 protein is isolated from cell lysates by incubation with a monoclonal anti- Axin2 antibody (R&D Systems #MAB6078) that is bound to fluorescent carboxybeads. Then, bound Axin2 is specifically detected with a polyclonal anti-Axin2 antibody (Cell Signaling #2151) and an appropriate PE- fluorescent secondary antibody. The amount of isolated Axin2 protein is determined in a Luminex200 machine (Luminex Corporation) according to the manufacturer's instruction by counting 100 events per well. Inhibition of Tankyrase by test compounds results in higher levels of Axin2 which directly correlates with an increase of detectable fluorescence. As controls cells are treated with solvent alone (neutral control) and with a Tankyrase reference inhibitor IWR-2 (3E-06 M) which refers as control for maximum increase of Axin2. For analysis, the obtained data were normalized against the untreated solvent control and fitted for determination of the EC50 values using the Assay Explorer software (Accelrys).
Biochemical activity testing of PARP-1: Autoparsylation assay
The autoparsylation assay was run in two steps: the enzymatic reaction in which His-tagged Parp- transferred biotinylated ADP-ribose/ADP-ribose to itself from biotinylated NAD/NAD as co-substrate and the detection reaction where a time resolved FRET between cryptate labelled anti-His antibody bound to the His tag of the enzyme and Xlent® labelled-streptavidin bound the biotin-parsylation residue was analysed. The autoparsylation activity was detectable directly via the increase in HTRF signal.
The autoparsylation assay was performed as 384-well HTRF® (Cisbio, Codolet, France) assay format in Greiner low volume nb 384-well microtiter plates. 35 nM His-tagged Parp-1 (human, recombinant, Enzo Life Sciences
GmbH, Lorrach, Germany) and a mixture of 125 nM bio-NAD (Biolog, Life science Inst., Bremen, Germany) and 800 nM NAD as co-substrate were incubated in a total volume of 6 μΙ (100 mM Tris/HCI, 4 mM Mg-chloride, 0.01 % IGEPAL® CA630, 1mM DTT , 0.5 % DMSO, pH 8, 13 ng/μΙ activated DNA (BPS Bioscience, San Diego, US)) in the absence or presence of the test compound (10 dilution concentrations) for 150 min at 23°C. The reaction was stopped by the addition of 4 μΙ of the Stop/detection solution (70 nM SA- Xlent® (Cisbio, Codolet, France), 2.5 nM Anti-His-K® (Eu-labelled anti-His, Cisbio, Codolet, France) in 50 mM HEPES, 400 mM KF, 0.1 % BSA, 20 mM EDTA, pH 7.0). After 1 h incubation at room temperature the HTRF was measured with an Envision multimode reader (Perkin Elmer LAS Germany GmbH) at excitation wavelength 340 nm (laser mode) and emission
wavelengths 615 nm and 665 nm. The ratio of the emission signals was determined. The full value used was the inhibitor-free reaction. The
pharmacological zero value used was Olaparib (LCIabs, Woburn, US) in a final concentration of 1 μΜ. The inhibitory values (IC50) were determined using either the program Symyx Assay Explorer® or Condosseo® from
GeneData.
Biochemical activity testing of TNKS 1 and 2: activity ELISA (Autoparsylation assay)
For analysis of autoparsylation activity of TNKS 1 and 2 an activity ELISA was performed: In the first step GST tagged TNKS was captured on a Glutathione coated plate. Then the activity assay with biotinylated NAD was performed in the absence/presence of the compounds.During the enzymatic reaction GST tagged TNKS transferred biotinylated ADP-ribose to itself from biotinylated NAD as co-substrate. For the detection streptavidin-HRP conjugate was added that bound to the biotinylated TNKS and was thereby captured to the plates. The amount of biotinylated resp autoparsylated TNKS was detected with a luminescence substrate for HRP. The level of the luminescence signal correlated directly with the amount of autoparsylated TNKS and therefore with activity of TNKS.
The acitivity ELISA was performed in 384 well Glutathione coated microtiter plates (Express capture Glutathione coated plate, Biocat, Heidelberg,
Germany). The plates were pre-equilibrated with PBS. Then the plates were incubated with 50 μΙ 20 ng/well GST-tagged Tnks-1 (1023-1327 aa, prepared in-house), respectively GST-tagged Tnks-2 (873-1166 aa, prepared in-house) in assay buffer (50 mM HEPES, 4 mM Mg-chloride, 0.05 % Pluronic F-68, 2 mM DTT, pH 7.7) overnight at 4°C. The plates were washed 3 times with PBS-Tween-20. The wells were blocked by incubation at room temperature for 20 minutes with 50 μΙ blocking buffer (PBS, 0.05 % Tween-20, 0.5 % BSA). Afterwards the plates were washed 3 times with PBS-Tween-20. The enzymatic reaction was performed in 50 μΙ reaction solution (50 mM HEPES, 4 mM Mg-chloride, 0.05 % Pluronic F-68, 1.4 mM DTT, 0.5 % DMSO, pH 7.7) with10 μΜ bio-NAD (Biolog, Life science Inst, Bremen, Germany) as co- substrate in the absence or presence of the test compound (10 dilution concentrations) for 1 hour at 30°C. The reaction was stopped by 3 times washing with PBS-Tween-20. For the detection 50 μΙ of 20ng/pl Streptavidin, HRP conjugate (MoBiTec, Gottingen, Germany) in PBS/0.05%Tween-
20/0.01 %BSA were added and the plates were incubated for 30 minutes at room temperature. After three times washing with PBS-Tween-20 50 μΙ of SuperSignal ELISA Femto Maximum sensitivity substrate solution
(ThermoFisherScientific (Pierce), Bonn, Germany) were added. Following a 1 minute incubation at room temperature luminescence signals were measured with an Envision multimode reader (Perkin Elmer LAS Germany GmbH) at 700 nm. The full value used was the inhibitor-free reaction. The
pharmacological zero value used was XAV-939 (Tocris) in a final
concentration of 5 μΜ. The inhibitory values (IC50) were determined using either the program Symyx Assay Explorer® or Condosseo® from GeneData.
