FIELD OF INVENTION

The present invention provides 4,5-a-annulated 1,2,4-triazolone compounds of general formula (I) as described and defined herein, methods of preparing said compounds, intermediate compounds useful for preparing said compounds, pharmaceutical compositions and combinations comprising said compounds, and the use of said compounds for manufacturing pharmaceutical compositions for the treatment or prophylaxis of diseases, in particular of hyperproliferative and/or inflammatory disorders, as a sole agent or in combination with other active ingredients.


BACKGROUND

The present invention provides 4,5-annulated 1,2,4-triazolone compounds of general formula (I) which inhibit Dihydroorotate Dehydrogenase (DHODH).


Acute myeloid leukemia (AML) is the most common acute leukemia in humans with a 5 year survival of only about 30%. AML is a malignancy of the myeloid line of blood cells. The incidence rates and chances of cure are highly age dependent. The chemotherapy standard of care for AML has not changed significantly over the last decades highlighting the need for novel therapies. A major hallmark of AML is differentiation arrest of the leukemic cells at early stages of cellular differentiation. The potential of leukemic differentiation therapy can be seen with the success of ATRA or arsenic trioxide inducing differentiation in acute promyelocytic leukemia (APL). Around 10% of AML belong to the APL subtype where leukemic cells are harbouring a chromosomal translocation resulting in fusions of oncoproteins involving the retinoic acid receptor. While treatment with ATRA or arsenic trioxide leads to a dramatic increase of patient survival, with overall survival rates of over 70%, unfortunately a comparable differentiation therapy for the non-APL AMLs is lacking (Management of acute promyelocytic leukemia: recommendations from an expert panel on behalf of the European LeukemiaNet, Sanz M. A. et al, Blood 2009, 113(9), 1875-1891). Therefore new therapies inducing differentiation of AML cells are of high interest and medical need.


Dihydroorotate Dehydroqenase (DHODH)


DHODH is located in the mitochondria and the enzyme responsible for the 4th and rate limiting step in de novo pyrimidine synthesis converting dihydroorotate to orotate (Dihydroorotat-ubiquinone oxidoreductase links mitochondria in the biosynthesis of pyrimidine nucleotides, Löffler M. et al, Molecular and Cellular Biochemistry 1997, 174, 125-129).


As pyrimdine production is essential for DNA and RNA synthesis DHODH is highly important for cellular proliferation. The enzyme is considered an attractive drug target for cancer, immunological, parasitic and viral diseases and DHODH small molecule inhibitors like Leflunomide/Teriflunomide and Brequinar have been approved for clinical use in Rheumatoid Arthritis and Multiple Sclerosis. Additionally, preclinical studies indicate that DHODH inhibitors may be useful for the treatment of haematological cancer indications, for the treatment of solid tumors (e.g., neuroblastoma, melanoma, colon, breast and lung tumors), for the treatment of parasitic diseases (e.g., malaria), and for viral disease therapy.


U.S. Pat. No. 6,444,613 B1 relates to the field of defoliants, in particular thidiazuron-comprising mixtures, and their use in crops of cotton. These mixtures comprise among others 2,4,5-trisubstituted 1,2,4-triazolone compounds as herbicides, which inhibit the enzyme protoporphyrinogen-(IX) oxidase (PPO inhibitors).


WO199802422 describes substituted aromatic carbonyl compounds, among others 2,4,5-trisubstituted 1,2,4-triazolone compounds, as herbicides.


From CN106543139 some triazolone compounds are known as agrochemicals.


US 2016/0251341 A1 describes triazole compounds as serine protease inhibitors useful for the inhibition of thrombin and/or kallikrein.


WO 2013/186692 A1 describes triazolone compounds as mPGES-1 inhibitors, useful in the treatment of pain and/or inflammation from a variety of diseases or conditions, such as asthma, osteoarthritis, rheumatoid arthritis, acute or chronic pain and neurodegenerative diseases.


WO2010/077686 A1 describes sirtuin-modulating compounds, e.g. isoindolinone and related compounds, and methods of use thereof. The sirtuin-modulating compounds may be used for increasing the lifespan of a cell, and treating and/or preventing a wide variety of diseases and disorders including, for example, diseases or disorders related to aging or stress, diabetes, obesity, neurodegenerative diseases, cardiovascular disease, blood clotting disorders, inflammation, cancer, and/or flushing as well as diseases or disorders that would benefit from increased mitochondrial activity.







DESCRIPTION OF THE INVENTION

It has now been found, and this partially constitutes the basis of the present invention, that the compounds of the present invention (e.g., 4,5-annulated 1,2,4-triazolone compounds of general formula (I)) have surprising and advantageous properties.


In particular, the compounds of the present invention have surprisingly been found to effectively inhibit DHODH and may therefore be used for the treatment or prophylaxis of disease including hyperproliferative and/or inflammatory disorders, such as cancer, for example.


In accordance with one aspect, the present invention provides compounds of general formula (I):

Definitions

The term “substituted” means that one or more hydrogen atoms on the designated atom or group are replaced with a selection from the indicated group, provided that the designated atom's normal valency under the existing circumstances is not exceeded. Combinations of substituents and/or variables are permissible.


The term “optionally substituted” means that the number of substituents can be equal to or different from zero. Unless otherwise indicated, it is possible that optionally substituted groups are substituted with as many optional substituents as can be accommodated by replacing a hydrogen atom with a non-hydrogen substituent on any available carbon or nitrogen atom. Commonly, it is possible for the number of optional substituents, when present, to be 1, 2, 3, 4 or 5, in particular 1, 2 or 3.


As used herein, the term “one or more”, e.g. in the definition of the substituents of the compounds of general formula (I) of the present invention, means “1, 2, 3, 4 or 5, particularly 1, 2, 3 or 4, more particularly 1, 2 or 3, even more particularly 1 or 2”.


As used herein, an oxo substituent represents an oxygen atom, which is bound to a carbon atom or to a sulfur atom via a double bond.


The term “ring substituent” means a substituent attached to an aromatic or nonaromatic ring which replaces an available hydrogen atom on the ring.


Should a composite substituent be composed of more than one parts, e.g. (C1-C3-alkoxy)-(C1-C6-alkyl)-, it is possible for the position of a given part to be at any suitable position of said composite substituent, i.e. the C1-C3-alkoxy part can be attached to any carbon atom of the C1-C6-alkyl part of said (C1-C3-alkoxy)-(C1-C6alkyl)- group. A hyphen at the beginning or at the end of such a composite substituent indicates the point of attachment of said composite substituent to the rest of the molecule. Should a ring, comprising carbon atoms and optionally one or more heteroatoms, such as nitrogen, oxygen or sulfur atoms for example, be substituted with a substituent, it is possible for said substituent to be bound at any suitable position of said ring, be it bound to a suitable carbon atom and/or to a suitable heteroatom.

As used herein, the term “leaving group” means an atom or a group of atoms that is displaced in a chemical reaction as stable species taking with it the bonding electrons. In particular, such a leaving group is selected from the group comprising: halide, in particular fluoride, chloride, bromide or iodide, (methylsulfonyl)oxy, [(trifluoromethyl)sulfonyl]oxy, [(nonafluorobutyl)-sulfonyl]oxy, (phenylsulfonyl)oxy, [(4-methylphenyl)sulfonyl]oxy, [(4-bromophenyl)sulfonyl]oxy, [(4-nitrophenyl)sulfonyl]oxy, [(2-nitrophenyl)sulfonyl]oxy, [(4-isopropylphenyl)sulfonyl]oxy, [(2,4,6-triisopropylphenyl)sulfonyl]oxy, [(2,4,6-trimethylphenyl)sulfonyl]oxy, [(4-tert-butyl-phenyl)sulfonyl]oxy and [(4-methoxyphenyl)sulfonyl]oxy.


The term “substituent” refers to a group “substituted” on, e.g. an alkyl, haloalkyl, cycloalkyl, heterocyclyl, heterocycloalkenyl, cycloalkenyl, aryl, or heteroaryl group at any atom of that group, replacing one or more hydrogen atoms therein. In one aspect, the substituent(s) on a group are independently any one single, or any combination of two or more of the permissible atoms or groups of atoms delineated for that substituent. In another aspect, a substituent may itself be substituted with any one of the above substituents. Further, as used herein, the phrase “optionally substituted” means unsubstituted (e.g., substituted with an H) or substituted.


It will be understood that the description of compounds herein is limited by principles of chemical bonding known to those skilled in the art. Accordingly, where a group may be substituted by one or more of a number of substituents, such substitutions are selected so as to comply with principles of chemical bonding with regard to valencies, etc., and to give compounds which are not inherently unstable. For example, any carbon atom will be bonded to two, three, or four other atoms, consistent with the four valence electrons of carbon.


By “subject” is meant a mammal, including, but not limited to, a human or non-human mammal, such as a bovine, equine, canine, ovine, rodent, or feline


It is possible for the compounds of general formula (I) to exist as isotopic variants. The invention therefore includes one or more isotopic variant(s) of the compounds of general formula (I), particularly deuterium-containing compounds of general formula (I).


The term “isotopic variant” of a compound or a reagent is defined as a compound exhibiting an unnatural proportion of one or more of the isotopes that constitute such a compound.


The expression “unnatural proportion” in relation to an isotope means a proportion of such isotope which is higher than its natural abundance. The natural abundances of isotopes to be applied in this context are described in “Isotopic Compositions of the Elements 1997”, Pure Appl. Chem., 70(1), 217-235, 1998.


Examples of such isotopes include stable and radioactive isotopes of hydrogen, carbon, nitrogen, oxygen, phosphorus, sulfur, fluorine, chlorine, bromine and iodine, such as 2H (deuterium), 3H (tritium), 11C, 13C, 14C 15N, 18O, 32P, 33P, 33S, 34S 35S, 36S, 18F, 36Cl, 82Br, 123I, 124I, 125I, 129I and 131I, respectively.


With respect to the treatment and/or prophylaxis of the disorders specified herein the isotopic variant(s) of the compounds of general formula (I) preferably contain deuterium (“deuterium-containing compounds of general formula (I)”). Isotopic variants of the compounds of general formula (I) in which one or more radioactive isotopes, such as 3H or 14C, are incorporated are useful e.g. in drug and/or substrate tissue distribution studies. These isotopes are particularly preferred for the ease of their incorporation and detectability. Positron emitting isotopes such as 18F or 11C may be incorporated into a compound of general formula (I). These isotopic variants of the compounds of general formula (I) are useful for in vivo imaging applications. Deuterium-containing and 13C-containing compounds of general formula (I) can be used in mass spectrometry analyses in the context of preclinical or clinical studies.


Isotopic variants of the compounds of general formula (I) can generally be prepared by methods known to a person skilled in the art, such as those described in the schemes and/or examples herein, by substituting a reagent for an isotopic variant of said reagent, preferably for a deuterium-containing reagent. Depending on the desired sites of deuteration, in some cases deuterium from D2O can be incorporated either directly into the compounds or into reagents that are useful for synthesizing such compounds. Deuterium gas is also a useful reagent for incorporating deuterium into molecules. Catalytic deuteration of olefinic bonds and acetylenic bonds is a rapid route for incorporation of deuterium. Metal catalysts (i.e. Pd, Pt, and Rh) in the presence of deuterium gas can be used to directly exchange deuterium for hydrogen in functional groups containing hydrocarbons. A variety of deuterated reagents and synthetic building blocks are commercially available from companies such as for example C/D/N Isotopes, Quebec, Canada; Cambridge Isotope Laboratories Inc., Andover, Mass., USA; and CombiPhos Catalysts, Inc., Princeton, N.J., USA.


The term “deuterium-containing compound of general formula (I)” is defined as a compound of general formula (I), in which one or more hydrogen atom(s) is/are replaced by one or more deuterium atom(s) and in which the abundance of deuterium at each deuterated position of the compound of general formula (I) is higher than the natural abundance of deuterium, which is about 0.015%. Particularly, in a deuterium-containing compound of general formula (I) the abundance of deuterium at each deuterated position of the compound of general formula (I) is higher than 10%, 20%, 30%, 40%, 50%, 60%, 70% or 80%, preferably higher than 90%, 95%, 96% or 97%, even more preferably higher than 98% or 99% at said position(s). It is understood that the abundance of deuterium at each deuterated position is independent of the abundance of deuterium at other deuterated position(s).


The selective incorporation of one or more deuterium atom(s) into a compound of general formula (I) may alter the physicochemical properties (such as for example acidity [C. L. Perrin, et al., J. Am. Chem. Soc., 2007, 129, 4490], basicity [C. L. Perrin et al., J. Am. Chem. Soc., 2005, 127, 9641], lipophilicity [B. Testa et al., Int. J. Pharm., 1984, 19(3), 271]) and/or the metabolic profile of the molecule and may result in changes in the ratio of parent compound to metabolites or in the amounts of metabolites formed. Such changes may result in certain therapeutic advantages and hence may be preferred in some circumstances. Reduced rates of metabolism and metabolic switching, where the ratio of metabolites is changed, have been reported (A. E. Mutlib et al., Toxicol. Appl. Pharmacol., 2000, 169, 102). These changes in the exposure to parent drug and metabolites can have important consequences with respect to the pharmacodynamics, tolerability and efficacy of a deuterium-containing compound of general formula (I). In some cases deuterium substitution reduces or eliminates the formation of an undesired or toxic metabolite and enhances the formation of a desired metabolite (e.g. Nevirapine: A. M. Sharma et al., Chem. Res. Toxicol., 2013, 26, 410; Efavirenz: A. E. Mutlib et al., Toxicol. Appl. Pharmacol., 2000, 169, 102). In other cases the major effect of deuteration is to reduce the rate of systemic clearance. As a result, the biological half-life of the compound is increased. The potential clinical benefits would include the ability to maintain similar systemic exposure with decreased peak levels and increased trough levels. This could result in lower side effects and enhanced efficacy, depending on the particular compound's pharmacokinetic/pharmacodynamic relationship. ML-337 (C. J. Wenthur et al., J. Med. Chem., 2013, 56, 5208) and Odanacatib (K. Kassahun et al., WO2012/112363) are examples for this deuterium effect. Still other cases have been reported in which reduced rates of metabolism result in an increase in exposure of the drug without changing the rate of systemic clearance (e.g. Rofecoxib: F. Schneider et al., Arzneim. Forsch./Drug. Res., 2006, 56, 295; Telaprevir: F. Maltais et al., J. Med. Chem., 2009, 52, 7993). Deuterated drugs showing this effect may have reduced dosing requirements (e.g. lower number of doses or lower dosage to achieve the desired effect) and/or may produce lower metabolite loads.


A compound of general formula (I) may have multiple potential sites of attack for metabolism. To optimize the above-described effects on physicochemical properties and metabolic profile, deuterium-containing compounds of general formula (I) having a certain pattern of one or more deuterium-hydrogen exchange(s) can be selected. Particularly, the deuterium atom(s) of deuterium-containing compound(s) of general formula (I) is/are attached to a carbon atom and/or is/are located at those positions of the compound of general formula (I), which are sites of attack for metabolizing enzymes such as e.g. cytochrome P450.


In another embodiment the present invention concerns a deuterium-containing compound of general formula (I) having 1, 2, 3 or 4 deuterium atoms, particularly with 1, 2 or 3 deuterium atoms.


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. The terms “a” or “an,” as used in herein means one or more.


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 the present invention optionally contain one or more asymmetric centres, depending upon the location and nature of the various substituents desired. It is possible that one or more asymmetric carbon atoms are present in the (R) or (S) configuration, which can result in racemic mixtures in the case of a single asymmetric centre, and in diastereomeric mixtures in the case of multiple asymmetric centres. In certain instances, it is possible that asymmetry 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.


Preferred isomers are those which produce the more desirable biological activity. These separated, pure or partially purified isomers or racemic 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., HPLC columns using a chiral phase), with or without conventional derivatisation, optimally chosen to maximise the separation of the enantiomers. Suitable HPLC columns using a chiral phase are commercially available, such as those manufactured by Daicel, e.g., Chiracel OD and Chiracel OJ, for example, among many others, which are all routinely selectable. Enzymatic separations, with or without derivatisation, are also useful. The optically active compounds of the present invention can likewise be obtained by chiral syntheses utilizing optically active starting materials.


In order to distinguish different types of isomers from each other reference is made to IUPAC Rules Section E (Pure Appl Chem 45, 11-30, 1976).


Isolation of a single stereoisomer, e.g. a single enantiomer or a single diastereomer, of a compound of the present invention is achieved by any suitable state of the art method, such as chromatography, especially chiral chromatography, for example.


Further, it is possible for the compounds of the present invention to exist as tautomers. For example, any compound of the present invention which contains an imidazopyridine moiety as a heteroaryl group for example can exist as a 1H tautomer, or a 3H tautomer, or even a mixture in any amount of the two tautomers, namely:

The compounds of the present invention can exist as a hydrate, or as a solvate, wherein the compounds of the present invention contain polar solvents, in particular water, methanol or ethanol for example, as structural element of the crystal lattice of the compounds. It is possible for the amount of polar solvents, in particular water, to exist in a stoichiometric or non-stoichiometric ratio. In the case of stoichiometric solvates, e.g. a hydrate, hemi-, (semi-), mono-, sesqui-, di-, tri-, tetra-, penta- etc. solvates or hydrates, respectively, are possible. The present invention includes all such hydrates or solvates.


Further, it is possible for the compounds of the present invention to exist in free form, e.g. as a free base, or as a free acid, or as a zwitterion, or to exist in the form of a salt. Said salt may be any salt, either an organic or inorganic addition salt, particularly any pharmaceutically acceptable organic or inorganic addition salt, which is customarily used in pharmacy, or which is used, for example, for isolating or purifying the compounds of the present invention.


The term “pharmaceutically acceptable salt” refers to an inorganic or organic acid addition salt of a compound of the present invention. For example, see S. M. Berge, et al. “Pharmaceutical Salts,” J. Pharm. Sci. 1977, 66, 1-19.

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.


Generally, the use of chemotherapeutic agents and/or anti-cancer agents in combination with a compound or pharmaceutical composition of the present invention will serve to:

    • 1. yield better efficacy in reducing the growth of a tumour or even eliminate the tumour as compared to administration of either agent alone,
    • 2. provide for the administration of lesser amounts of the administered chemotherapeutic agents,
    • 3. provide for a chemotherapeutic treatment that is well tolerated in the patient with fewer deleterious pharmacological complications than observed with single agent chemotherapies and certain other combined therapies,
    • 4. provide for treating a broader spectrum of different cancer types in mammals, especially humans,
    • 5. provide for a higher response rate among treated patients,
    • 6. provide for a longer survival time among treated patients compared to standard chemotherapy treatments,
    • 7. provide a longer time for tumour progression, and/or
    • 8. yield efficacy and tolerability results at least as good as those of the agents used alone, compared to known instances where other cancer agent combinations produce antagonistic effects.


In addition, the compounds of general formula (I) of the present invention can also be used in combination with radiotherapy and/or surgical intervention.


In a further embodiment of the present invention, the compounds of general formula (I) of the present invention may be used to sensitize a cell to radiation, i.e. 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 present invention. In one aspect, the cell is treated with at least one compound of general formula (I) of the present invention.


Thus, the present invention also provides a method of killing a cell, wherein a cell is administered one or more compounds of the present 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 general formula (I) of the present 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 general formula (I) of the present 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 other embodiments of the present invention, a cell is killed by treating the cell with at least one DNA damaging agent, i.e. after treating a cell with one or more compounds of general formula (I) of the present 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. cis platin), ionizing radiation (X-rays, ultraviolet radiation), carcinogenic agents, and mutagenic agents.


In other embodiments, 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 general formula (I) of the present 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 general formula (I) of the present 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 general formula (I) of the present 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.

One example of a “fixed combination” is a pharmaceutical composition wherein a first active ingredient and a further 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 a first active ingredient and a further 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 a first active ingredient and a further 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 first active ingredient and the further active ingredient are present separately. It is possible for the components of the non-fixed combination or kit-of-parts to be administered separately, sequentially, simultaneously, concurrently or chronologically staggered.


The compounds of the present invention can be administered as the sole pharmaceutical agent or in combination with one or more other pharmaceutically active ingredients where the combination causes no unacceptable adverse effects.

Based upon standard laboratory techniques known to evaluate compounds useful for the treatment of hyperproliferative and/or inflammatory 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 active ingredients or medicaments that are used to treat these conditions, the effective dosage of the compounds of the present 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, it is possible for “drug holidays”, in which a patient is not dosed with a drug for a certain period of time, to be beneficial to the overall balance between pharmacological effect and tolerability. It is possible for a unit dosage to contain from about 0.5 mg to about 1500 mg (e.g. about 0.5 mg to about 5 mg, about 5 mg to about 50 mg, about 50 mg to about 500 mg, about 500 mg to about 1500 mg, etc.) 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.


In other embodiments of the invention the total amount of the active ingredient to be administered will generally range from 0.001 mg/kg to 200 mg/kg body weight per day, and preferably from 0.01 mg/kg to 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, it is possible for “drug holidays”, in which a patient is not dosed with a drug for a certain period of time, to be beneficial to the overall balance between pharmacological effect and tolerability. It is possible for a unit dosage to contain from 0.5 mg to 1500 mg of active ingredient, and can be administered one or more times per day or less than once a day.


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.


EXPERIMENTAL SECTION

NMR peak forms are stated as they appear in the spectra, possible higher order effects have not been considered.


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 H-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 http://www.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%.


Chemical names were generated using the ACD/Name software from ACD/Labs. In some cases generally accepted names of commercially available reagents were used in place of ACD/Name generated names.

The various aspects and embodiments of the invention described in this application are illustrated by the following examples which are not meant to limit the invention in any way.


The example testing experiments described herein serve to illustrate the present invention and the invention is not limited to the examples given.


EXPERIMENTAL SECTION—GENERAL PART

All reagents, for which the synthesis is not described in the experimental part, are either commercially available, or are known compounds or may be formed from known compounds by known methods by a person skilled in the art.


The compounds and intermediates produced according to the methods of the invention may require purification. Purification of organic compounds is well known to the person skilled in the art and there may be several ways of purifying the same compound. In some cases, no purification may be necessary. In some cases, the compounds may be purified by crystallization.


In some cases, impurities may be stirred out using a suitable solvent. In some cases, the compounds may be purified by chromatography, particularly flash column chromatography, using for example prepacked silica gel cartridges, e.g. Biotage SNAP cartidges KP-Sil® or KP-NH® in combination with a Biotage autopurifier system (SP4® or Isolera Four®) and eluents such as gradients of hexane/ethyl acetate or DCM/methanol. In some cases, the compounds may be purified by preparative HPLC using for example a Waters autopurifier equipped with a diode array detector and/or on-line electrospray ionization mass spectrometer in combination with a suitable prepacked reverse phase column and eluents such as gradients of water and acetonitrile which may contain additives such as trifluoroacetic acid, formic acid or aqueous ammonia.


In some cases, purification methods as described above can provide those compounds of the present invention which possess a sufficiently basic or acidic functionality in the form of a salt, such as, in the case of a compound of the present invention which is sufficiently basic, a trifluoroacetate or formate salt for example, or, in the case of a compound of the present invention which is sufficiently acidic, an ammonium salt for example. A salt of this type can either be transformed into its free base or free acid form, respectively, by various methods known to the person skilled in the art, or be used as salts in subsequent biological assays. It is to be understood that the specific form (e.g. salt, free base etc.) of a compound of the present invention as isolated and as described herein is not necessarily the only form in which said compound can be applied to a biological assay in order to quantify the specific biological activity.

To a solution of 4-bromo-2-{[(2S)-1,1,1-trifluoropropan-2-yl]oxy}benzoic acid (intermediate 13) (2.6 g, 8.3 mmol) in dichloromethane (42 ml) was added N,N-dimethylformamide (870 μl), followed by dropwise addition of ethanedioyl dichloride (870 μl, 10 mmol). The reaction mixture was stirred at room temperature for one hour, and concentrated under reduced pressure. The title compound was obtained as brown oil (15.84 g, quantitative), which was used for the next step without purification. For analytic, a small amount of the product was treated with methanol, to yield the corresponding methyl ester, which was detected by LC-MS.

To a −10° C. stirred solution of (S)-(+)-2-pentanol (1.16 g, 13.2 mmol) in anhydrous tetrahydrofuran (13.2 ml) was added a 1.0 M solution of potassium 1,1,1,3,3,3-hexamethyldisilazan-2-ide in tetrahydrofuran dropwise (7.20 ml, 7.20 mmol). The resulting mixture was then stirred at −10° C. for 1 hour, after which the resulting alkoxide solution was added dropwise to a stirred solution of tert-butyl 2,5-difluoro-4-(3-oxo-5,6,7,8-tetrahydro[1,2,4]triazolo[4,3-a]pyridin-2(3H)-yl)benzoate (intermediate 2) (2.11 g, 6.00 mmol) in anhydrous tetrahydrofuran (6.00 ml). The resulting orange solution was stirred at −10° C. for 2 hours and then concentrated under reduced pressure to give a orange solid. The residue was purified by flash column chromatography to give a mixture of esters as a colourless oil. The residue was suspended in a 4:1 ration of 1,4-dioxane/water (30.0 ml) after which lithium hydroxide (2.16 g, 90.0 mmol) was added in one portion. The resulting mixture was heated at 70° C. for 16 hours and cooled to room temperature. Water (20 ml) was added to the mixture followed by washing with diethyl ether (20 ml). The aqueous layer was acidified to pH 2.0 with concentrated hydrochloric acid and then extracted with diethyl ether (3×20 ml). The combined organic extracts were washed with brine (20 ml), dried over magnesium sulfate, filtered and concentrated under reduced pressure to give a cream solid. The residue was purified by flash column chromatography to give 5-fluoro-4-(3-oxo-5,6,7,8-tetrahydro[1,2,4]triazolo[4,3-a]pyridin-2(3H)-yl)-2-[(2S)-pentan-2-yloxy]benzoic acid as a cream solid (1.06 g, 48%).

The resulting mixture was warmed to room temperature, stirred for 90 minutes and concentrated under reduced pressure. A solution of the crude acid chloride in dichloromethane (1.0 ml) was then added dropwise to a 0° C. stirred solution of 2,6-difluoroaniline (29 mg, 226 μmol) and triethylamine (32 μl, 230 μmol) in anhydrous dichloromethane (2.0 ml). Following complete addition, the mixture was warmed to room temperature, stirred for 2 hours and concentrated under reduced pressure. The residue was dissolved in DMSO, filtered through a teflon filter and purified by reverse phase column chromatography (acetonitrile, 0.1% aqueous formic acid) to give the amide as a white solid (88 mg, 86%).

Plasmid 1: pACYC_pelB_POR:


The pACYC_pelB_POR-plasmid is a derivate of the commercially available pACYC(Duet)-plasmid of the company Novagen. To generate this plasmid two fragments, pACYC_mod and pelB_POR were ligated.


Creation of the pelB_POR Fragment:


The human NAPDH hemoprotein reductase (POR) was amplified via two primer containing the restriction sites BamHI (GAGGATCCGATGGGAGACTCCCACGTG) (SEQ ID NO: 3) and SalI (GAGAGTCGACCTAGCTCCACACGTCCAG) (SEQ ID NO: 4) out of the plasmid pMPSV-CMV::hOR. pMPSV-CMV::hOR plasmid (1 μL) was mixed with MilliQ water (51.5 μL), expand buffer with MgCl2 (7.5 μL), dNTPs (6 μL), Taq-Expand (1 μL), forward primer (4 μL) and reverse primer (4 μL). The PCR was performed according to the following procedure: 1) 94° C. for 5 minutes, 2) 94° C. for 30 seconds, 3) 60° C. for 30 seconds, 4) 72° C. for 90 seconds, 5) go back to step 2 (30 cycles), 6) 72° C. for 5 minutes, 7) 15° C. forever. To combine the POR with an upstream pelB-sequence, the POR has to be cloned into the empty vector pET22b+. As well as the amplified PCR fragment the empty vector pET22b+, provided by the company Novagen, was digested with the restriction enzymes BamHI and SalI. The first digestion was performed with BamHI. Either the empty vector pET22b+ or the amplified PCR fragment (30 μL) was mixed with 10× buffer NEB3.1 (4 μl), BSA solution (10 mg/mL, 0.4 μL), BamHI restriction enzyme (1 μL) and MilliQ water (5 μL). After incubation at 37° C. for 1 hour the reaction was stopped by incubating for 20 minutes at 65° C. The digested PCR fragment and empty vector pET22b+ were purified via the QIAquick PCR Purification kit from Qiagen. Afterwards the second digestion was performed with SalI. Either the BamHI digested empty vector pET22b+ or the BamHI digested PCR fragment (30 μL) was mixed with 10× buffer NEB3.1 (4 μl), BSA solution (10 mg/mL, 0.4 μL), SalI restriction enzyme (1 μL) and MilliQ water (5 μL). After incubation at 37° C. for 1 hour the reaction was stopped by incubating for 20 minutes at 65° C. For the double-digested vector a dephosphorylation with a shrimp alkaline phosphatase followed. The double-digested empty vector pET22b+(40 μL) was mixed with 10×SAP buffer (5 μl), SAP enzyme (2 μL) and MilliQ water (3 μL). After incubation at 37° C. for 30 minutes the reaction was stopped by incubating for 20 minutes at 65° C. The double-digested PCR fragment and the dephosphorylated double-digested empty vector were purified via the QIAquick PCR Purification kit from Qiagen. Afterwards a gel extraction with the QIAquick Gel Extraction Kit from Qiagen followed. The ligation of the double-digested POR and the double-digested pET22b+-vector was performed with T4 DNA Ligase. Cut vector (1 μL) was mixed with PCR product (1 μL), 10× Ligase buffer with 10 mM ATP (1.5 μL), T4 DNA Ligase (1 μL) and MilliQ water (10.5 μL). After incubation for 30 minutes at room temperature the ligated DNA was purified by ethanol precipitation. Ligated DNA (15 μL) was mixed with glycogen (1 μL), ammonium acetate (7.5 μL) and 100% ethanol (37.5 μL). After 5 minutes at room temperature a centrifugation at 14000 rpm for 5 minutes was used to precipitate the DNA. The supernatant was removed and the DNA washed with 75% ethanol (100 μL), before the DNA was air-dried and resuspended in MilliQ water (12 μL). The ligated DNA was digested with the restriction enzymes NdeI und XhoI. The first digestion was performed with NdeI. The ligated DNA (30 μL) was mixed with 10× buffer NEB4 (4 μl), NdeI restriction enzyme (1 μL) and MilliQ water (5 μL). After incubation at 37° C. for 1 hour the reaction was stopped by incubating for 20 minutes at 65° C. The digested vector was purified via the QIAquick PCR Purification kit from Qiagen. Afterwards the second digestion was performed with XhoI. The NdeI digested DNA (30 μL) was mixed with 10× buffer NEB4 (4 μl), BSA solution (10 mg/mL, 0.4 μL), XhoI restriction enzyme (1 μL) and MilliQ water (5 μL). After incubation at 37° C. for 1 hour the reaction was stopped by incubating for 20 minutes at 65° C. The double-digested DNA was purified via the QIAquick PCR Purification kit from Qiagen. Afterwards a gel extraction with the QIAquick Gel Extraction Kit from Qiagen followed to isolate the pelB_POR fragment.


Creation of the pACYC_mod Fragment:


To change the upstream promotor of the pACYC(Duet)-vector, the pACYC(Duet)-vector as well as the pCW_CYP1A2 vector, provided by the company Oxford Biomedical Research, was digested with the restriction enzymes MluI and XhoI.


The first digestion was performed with MluI. Either the pACYC(Duet)-vector or the pCW_CYP1A2 vector (30 μL) was mixed with 10× buffer NEB3.1 (4 μl), BSA solution (10 mg/mL, 0.4 μL), MluI restriction enzyme (1 μL) and MilliQ water (5 μL).

The double-digested CYP1A2 fragment and the dephosphorylated double-digested pACYC(Duet) vector were purified via the QIAquick PCR Purification kit from Qiagen. Afterwards a gel extraction with the QIAquick Gel Extraction Kit from Qiagen followed. The ligation of the double-digested CYP1A2 fragment and the double-digested pACYC(Duet)-vector was performed with T4 DNA Ligase. The cut vector (1 μL) was mixed with cut CYP1A2 fragment (1 μL), 10× Ligase buffer with 10 mM ATP (1.5 μL), T4 DNA Ligase (1 μL) and MilliQ water (10.5 μL).

The human monooxygenase CYP2C19 was amplified via two primer containing the restriction sites NdeI (CCATCGATCATATGGCTCGACAATCTTCTGGACGAGGAAAACTCCCT) (SEQ ID NO: 5) and XhoI (ATTGAGACTCGAGTCAGACAGGAATGAAGCACA) (SEQ ID NO: 6) out of the plasmid pBLUESCRIPTS SK+_2C19. Using the forward primer containing the NdeI restriction site the first 20 amino acids of the CYP2C19 enzymes were deleted und lead to the Δ3_CYP2C19 fragment.


pBLUESCRIPTS SK+_2C19 (1 μL) was mixed with MilliQ water (51.5 μL), expand buffer with MgCl2 (7.5 μL), dNTPs (6 μL), Taq-Expand (1 μL), forward primer (4 μL) and reverse primer (4 μL). The PCR was performed after following program: 1) 94° C. for 5 minutes, 2) 94° C. for 30 seconds, 3) 60° C. for 30 seconds, 4) 72° C. for 90 seconds, 5) go back to step 2 (30 cycles), 6) 72° C. for 5 minutes, 7) 15° C. forever. The amplified PCR fragment was then digested with the restriction enzymes NdeI and XhoI. The first digestion was performed with NdeI. The amplified 25 PCR fragment (30 μL) was mixed with 10× buffer NEB4 (4 μl), NdeI restriction enzyme (1 μL) and MilliQ water (5 μL). After incubation at 37° C. for 1 hour the reaction was stopped by incubating for 20 minutes at 65° C. The digested PCR fragment was purified via the QIAquick PCR Purification kit from Qiagen. Afterwards the second digestion was performed with XhoI.


The NdeI digested PCR fragment (30 μL) was mixed with 10× buffer NEB4 (4 μl), BSA solution (10 mg/mL, 0.4 μL), XhoI restriction enzyme (1 μL) and MilliQ water (5 μL). After incubation at 37° C. for 1 hour the reaction was stopped by incubating for 20 minutes at 65° C. The double-digested PCR fragment was purified via the QIAquick PCR Purification kit from Qiagen. Afterwards a gel extraction with the QIAquick Gel Extraction Kit from Qiagen followed to isolated the Δ3_CYP2C19 fragment.


Creation of the pETDuet_mod Fragment:


To change the upstream promotor of the pETDuet-1-vector, the pETDuet-1-vector as well as the pCW_CYP1A2 vector, provided by the company Oxford Biomedical Research, was digested with the restriction enzymes MluI and XhoI.


The first digestion was performed with MluI. Either the pETDuet-1-vector or the pCW_CYP1A2 vector (30 μL) was mixed with 10× buffer NEB4 (4 μl), BSA solution (10 mg/mL, 0.4 μL), MluI restriction enzyme (1 μL) and MilliQ water (5 μL). After incubation at 37° C. for 1 hour the reaction was stopped by incubating for 20 minutes at 65° C. The digested vector was purified via the QIAquick PCR Purification kit from Qiagen. Afterwards the second digestion was performed with XhoI. Either the MluI digested pETDuet-1-vector or the MluI digested pCW_CYP1A2 (30 μL) was mixed with 10× buffer NEB4 (4 μl), BSA solution (10 mg/mL, 0.4 μL), XhoI restriction enzyme (1 μL) and MilliQ water (5 μL). After incubation at 37° C. for 1 hour the reaction was stopped by incubating for 20 minutes at 65° C. For the double-digested pETDuet-1-vector a dephosphorylation with a shrimp alkaline phosphatase followed. The double-digested pETDuet-1 vector (40 μL) was mixed with 10×SAP buffer (5 μl), SAP enzyme (2 μL) and milliQ water (3 μL). After incubation at 37° C. for 30 minutes the reaction was stopped by incubating for 20 minutes at 65° C. The double-digested CYP1A2 fragment and the dephosphorylated double-digested pETDuet-1 vector were purified via the QIAquick PCR Purification kit from Qiagen. Afterwards a gel extraction with the QIAquick Gel Extraction Kit from Qiagen followed. The ligation of the double-digested CYP1A2 fragment and the double-digested pETDuet-1-vector was performed with T4 DNA Ligase. The cut vector (1 μL) was mixed with cut CYP1A2 fragment (1 μL), 10× Ligase buffer with 10 mM ATP (1.5 μL), T4 DNA Ligase (1 μL) and MilliQ water (10.5 μL). After incubation for 30 minutes at room temperature the ligated DNA was purified by ethanol precipitation. Ligated DNA (15 μL) was mixed with glycogen (1 μL), ammonium acetate (7.5 μL) and 100% ethanol (37.5 μL). After 5 minutes at room temperature a centrifugation at 14000 rpm for 5 minutes was used to precipitate the DNA. The supernatant was removed and the DNA washed with 75% ethanol (100 μL), before the DNA was air-dried and resuspended in MilliQ water (12 μL). The ligated DNA was digested with the restriction enzymes NdeI und XhoI. The first digestion was performed with NdeI. The ligated DNA (30 μL) was mixed with 10× buffer NEB4 (4 μl), NdeI restriction enzyme (1 μL) and MilliQ water (5 μL). After incubation at 37° C. for 1 hour the reaction was stopped by incubating for 20 minutes at 65° C. The digested vector was purified via the QIAquick PCR Purification kit from Qiagen. Afterwards the second digestion was performed with XhoI. The NdeI digested DNA (30 μL) was mixed with 10× buffer NEB4 (4 μl), BSA solution (10 mg/mL, 0.4 μL), XhoI restriction enzyme (1 μL) and MilliQ water (5 μL). After incubation at 37° C. for 1 hour the reaction was stopped by incubating for 20 minutes at 65° C. Afterwards the double-digested pETDuet_mod-vector was a dephosphorylated with a shrimp alkaline phosphatase. The vector (40 μL) was mixed with 10×SAP buffer (5 μl), SAP enzyme (2 μL) and milliQ water (3 μL). After incubation at 37° C. for 30 minutes the reaction was stopped by incubating for 20 minutes at 65° C. It followed a PCR purification via the QIAquick PCR Purification kit from Qiagen.

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.


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.


The in vitro activity of the compounds of the present invention can be demonstrated in the following assays:


In Vitro Assay 1: DHODH Enzymatic Assay-1


The enzymatic assay couples DHODH activity with bleaching of the dye 2,6-dichlorophenolindophenol (DCIP) (Knecht and Loffler, 1998; Miller et al., 1968). The assay was conducted in buffer containing 50 mM Tris, 0.1% Triton X-100, 150 mM potassium chloride, 2 nM DHODH, 1 mM dihydroorotate, 0.1 mM decylubiquinone, 0.06 mM DCIP, and 2% DMSO at pH 8.0 at 32 degree celsius. The reaction was initiated by addition of substrates. Enzyme activity was monitored kinetically by the reduction in DCIP absorbance at 600 nm. Purified recombinant human DHODH enzyme was purchased from Novus (cat. no. NBP1-98916). Other chemicals were purchased from Sigma-Aldrich. Absorbance measurements were obtained using a BMG clarion star plate-reading spectrophotometer.


In Vitro Assay 2: DHODH Enzymatic Assay-2


The enzymatic assay couples DHODH activity with bleaching of the dye 2,6-Dichlorophenolindophenol (DCIP) (Knecht and Loffler, 1998; Miller et al., 1968). The assay was conducted in aqueous buffer containing 50 mM Tris, 0.1% Triton X-100, 150 mM potassium chloride, 0.4 μg/mL DHODH, 1 mM dihydroorotate, 0.1 mM decylubiquinone, 0.06 mM DCIP, and 0.17% DMSO at pH 8.0 at room temperature. Compounds were added via pin transfer or via D300 digital dispenser, and the reaction was initiated by addition of substrates. Enzyme activity was monitored kinetically by the reduction in DCIP absorbance at 600 nm. Purified recombinant human DHODH (full-length, C-terminal MYC/DDK-tag) enzyme was purchased from Origene (cat. no. TP039034). Other chemicals, including leflunomide and teriflunomide, were purchased from Sigma-Aldrich. Absorbance measurements were obtained using a Molecular Devices Spectramax M5 plate-reading spectrophotometer.


In Vitro Assay 3: H460 (Lung Cancer)


Alamar Blue:


4000 cells/well of NCI-H460 cells were seeded in 90% RPMI 1640 (Invitrogen, #22400-089) and 10% fetal bovine serum (Invitrogen, #10099-141) and Penicillin/Streptomycin in 96 well plates. The next day, cells were incubated with different concentrations of test compounds for 72h. Cellular viability was analysed incubating cells with 12 μl of Alamar Blue (Invitrogen) per well for 2 hours at 37° C. Finally the plate was analysed using excitation wavelength: 544 nm and emission wavelength: 590 nm.


CellTiter-Glo®:


250 cells/well of NCI-H460 cells were seeded in 90% RPMI 1640 (Invitrogen, #22400-089) and 10% fetal bovine serum (Invitrogen, #10099-141) and Penicillin/Streptomycin in 96 well plates. The next day, cells were incubated with different concentrations of test compounds for 72h. Cellular viability was analyzed using CellTiter-Glo® Luminescent Cell Viability Assay (Promega, #G7572) according to manufacturer's instructions.


In Vitro Assay 4: THP-1 Proliferation Assay-1 (AML)


2000 cells/well of THP-1 cells were seeded in RPMI 1640 with Glutamax (Gibco, #11875-093) and 10% fetal calf serum (Biochrom, #S0615) in 384-well plates.

In Vitro Assay 5: THP-1 Proliferation Assay-2


Tumor and normal cells are cultivated in their respective media (ATCC recommended media). On day 1 of the assay, adherent cells are detached from the culture vessels by trypsinization. Suspension cells are centrifuged at 300×g and resuspended in fresh media. Cells are seeded at densities of 300-1000 cells/30 μL/well in the inner wells of white 384-well plates (Perkin Elmer). The outer wells of each plate are filled with 60 μL PBS/well to reduce evaporation. One plate is used for treatment of cells, the second plate is the start plate. All plates are incubated at 37° C., 5% CO2 for 24 hrs. On day 2, 30 μL/well of CellTiter Glow (CTG, Promega) is added to the start plate, the plate is shaken at rt for 10 min on a laboratory plate shaker and then the plate is read in a Infinite M200 Pro MTP Reader (Tecan, Luminescence, 0.1s). Compounds from a 10 mM stock (in DMSO) are added in triplicates to the treatment plate in tenfold dilutions (from 1E−6M to 1E−12M) with a HP D300 Digital Dispenser (the dispenser adds substances to wells in nanoliter volumes, therefore any volume added with this device does not count toward the final volume in the well). For rescue/specificity experiments with uridine, 100 μM uridine/well (diluted from a 10 mM stock solution in DMSO; Sigma-Aldrich) are added with the HP D300 Digital Dispenser. Treatment plates are incubated for a further 72 hrs at 37° C., 5% carbon dioxide, On day 5 of the assay, 30 μL/well of CellTiter Glow (CTG, Promega) is added to the treatment plate, the plate is shaken at rt for 10 min on a laboratory plate shaker and then the plate is read in a Infinite M200 Pro MTP Reader (Tecan, Luminescence, 0.1s).

Briefly, cells are harvested from exponential phase cultures, counted and plated in 96-well flat-bottom microtiter plates at a cell density of 4,000-60,000 cells/well depending on the cell line's growth rate. After a 24 h recovery period to allow the cells to resume exponential growth, 10 μl of culture medium (four control wells/plate) or of culture medium with test compound are added. The compound is applied at 10 concentrations in duplicate in half-log increments up to 30 μM and treatment is continued for three days. After three days treatment of cells, 20 μl/well CellTiter-Blue® reagent is added. Following an incubation period of up to four hours, fluorescence (FU) is measured by using the Enspire Multimode Plate Reader (excitation λ=531 nm, emission λ=615 nm).
