Novel heterocyclic NF-κB Inhibitors

The present invention relates to compounds of the general formula (Ia), (Ib), (Ic), (Di), (II), or (III) or a stereoisomer thereof or possible pharmaceutically acceptable salts thereof with an acid or a base, or pharmaceutically acceptable prodrugs of these compounds. The compounds of the invention can be used as a medicament and are exceptionally useful for the treatment of diseases associated with abnormal and hyperproliferation of cells in mammals, especially in humans, hi particular, they are useful for the treatment of diseases characterized by a hyperproliferation of T-cells. The present invention relates to compounds which are suitable for the therapy of diseases that can be treated by modulating cellular pathways in eukaryotes, e.g. cancer, immunological or inflammatory disorders, and viral infections, to processes for the preparation of these compounds, and to their use.

T-cell homeostasis is critical for the maintenance of immune tolerance. Defects in T-cell homeostasis can lead to autoimmune pathology. Autoimmune diseases include a large spectrum of clinically distinct entities that share a common aetiology, a misguided, self- directed immune response. This immune response can also be the consequence of an organ transplant. Evidence suggests a prime role of T-cell reactivity in autoimmune diseases. Measuring proliferative responses in T-lymphocytes is a widely used assay to measure immune competence (Killestein, J. et al. J. Neuroimmunol. 133,217-24, 2002).

We used a nonradioactive technique for the measurement of in vitro T-cell proliferation (Messele, T. et al. Clinical and Diagnostic Laboratory Immunology 687-692, 2000). Peripheral blood mononuclear cells (PBMCs) were isolated from human blood obtained from volunteer donators. PBMCs were isolated by centrifugation in ACCUSPIN tubes using HISTOPAQUE. PBMCS were stimulated with PHA and cell proliferation was measured with a Roche colorimetric BromUridin incorporation ELISA kit.

Regulation of the immune response is controlled by a variety of signalling pathways such as T-cell or TNF receptor signalling (Chen, G. et al. Science 296, 1634-1635, 2002). To further characterize targets of compounds which we found active in the T-cell proliferation assay, we tested the compounds on their ability to inhibit the human proteasome.

The major neutral proteolytic activity in the cytosol and nucleus is the proteasome, a 2OS (700 kDa) particle with multiple peptidase activities. The continual turnover of cellular proteins by the ubiquitin-proteasome pathway is used by the immune system to screen for the presence of abnormal intracellular proteins (Dantuma, N.P. et al. Nat. Biotechnol. 2000, 18(5), 538-43; Goldberg, AL. et al. Nature 357, 375, 1993). The ubiquitin- proteasome pathway plays an essential role in the regulation of NF-κB activity, being responsible for the degradation of the inhibitor IκB-α. In order to be targeted for degradation by the proteasome, IκB-α must first undergo selective phosphorylation at serine residues 32 and 36, followed by ubiquitinylation (Chen, ZJ. et al. Cell 84, 853-862, 1996; Brown, K. et al. Science 267, 1485, 1995). NF-κB, a transcription factor, regulates the transcription of an important set of genes, involved in inflammatory responses (Baeuerle, PA. et al. Cell 87, 1, 13-20, 1996). Proteasome inhibitors block IκB-α degradation and NF-κB activation (Traeckner et al. EMBOJ. 13, 5433, 1994).

Literature describing proteasome inhibitors has been described in reviews (Adams, J. et al. Ann. Rev. Med. Chem. 31, 279-288, 1996) and in patents US 6117887, US 5834487, WO 00/004954, WO 00/04954, WO 00/170204, WO 00/33654, WO 00/64863, WO 00/114324, WO 99/15183, WO 99/37666.

Here we describe novel chemical entities with proteasome inhibitory activity.

NF-κB (Nuclear Factor- KB) is a eukaryotic transcription factor of the rel family, which is located in the cytoplasm in an inactive complex, as a homo- or heterodimer. Predominantly it exists as a heterodimer composed of p50 and p65 subunits, bound to inhibitory proteins of the IKB family, usually IκB-α (D. Thanos et al, Cell 80, 529, 1995). NF-KB is activated in response to different stimuli, among which inflammatory cytokines, UV radiation,

phorbol esters, bacterial and viral infections. Stimulation triggers the release of NF-κB from IKB in consequence of the phosphorylation and the following degradation of the IKB- α protein (P. A. Baeuerle et al, Annu. Rev. Immunol. 12, 141, 1995) by the proteasome. Once it is set free, NF-κB translocates in the nucleus where it binds to the DNA at specific κB-sites and induces the transcription of a variety of genes encoding proteins involved in controlling the immune and inflammatory responses, amongst others interleukins, TNF-α, the NO-synthase and the cyclooxygenase 2 (S. Grimm et al, J. Biochem. 290, 297, 1993). Accordingly, NF-κB is considered an early mediator of the immune and inflammatory responses and it is involved in the control of cell proliferation and in the pathogenesis of various human diseases, such as rheumatoid arthritis (H. Beker et al, Clin. Exp. Immunol. 99, 325, 1995), ischemia (A. Salminen et al, Biochem. Biophys. Res. Comm. 212, 939, 1995), arteriosclerosis (A.S. Baldwin, Annals Rev. Immunol. 212, 649, 1996), as well as in the pathogenesis of AIDS. Inhibition of NF-κB mediated gene transcription can be accomplished through inhibition of phosphorylation of the inhibitory protein IKB, inhibition of IKB degradation, inhibition of NF-κB (p50/p65) nuclear translocation, the inhibition of NF-KB-DNA binding or NF-κB-mediated DNA transcription (J.C. Epinat et al, Oncogene 18, 6896, 1999).

Piperidin-4yl-thiazole-4-carboxamide can be prepared by various methodes described in the literature. One such example is the oxidation of the appropriate 2,5-dihydrothiazoles as described in Houben-Weyl, 2002, 730. The dihydrothiazoles can also be synthesised by methodes described in the same reference or described in You, S., Razavi, H., Kelly, J. W. Angew. Chem. 2003, 115, 87 or Katritzky, AR., Cai, C, Suzuki, K., Singh, SK. J. Org. Chem. 2004, 69, 811-814 and references in both papers. Alternative methods were described by Yasuchika, S. et. al. Heterocycles, Vol. 57, No. 5, 2002.

The compounds of formula (II), (Ic), and (III) carrying a further substituent on the heterocycle can be obtained via various methods described in Organic Syntheses, Coll, Vol.9, p.155; and Vol.74, p.229; J. Org. Chem., 1975, VoUO, No.10, page 1521, J. Am. Chem. Søc.96:19/September 18,1974; J. Org.

One possibility for the synthesis of substituted benzimindazole-substituent of formula (III) is described in Synthesis, 2006, 4, 597-602.

One possibility for the synthesis of compounds of formula (Ilia, c and Ha, b) (see scheme 1) comprises a step of reacting a compound of formula (V) with a compound of formula

(VI) under classical amide coupling conditions, like e.g. HBTU, iPr ₂ NEt, DMF, 0°C to r.t. to obtain intermediate (VII). Another alternative for this step might be the reaction of (V) with the corresponding acid chloride of (VI) to yield (VII). In a second step, compound

(VII) is saponified with a 1 M NaOH solution, obtaining the expected acid (VIII) in almost quantitative yield. This step could be realized under acidic conditions as well. Finally, another amide coupling step (with primary or secondary amines), which works similarily to step 1 described above, completes the synthesis for compounds of type (Ilia, c and Ha, and b).

Scheme 1 Synthesis of derivatives of type (Ilia, c) and (Ha, b)

Compounds dealing with structure (HIb, d, e, f) and (Hc, d) can be synthesized according to the procedure displayed in scheme 2. Herein, a heterocycle (DC) is reacted with a bromocompound (X), by means of a nucleophilic substitution reaction, to gain a bicyclic ester (XI), which is then saponified under standard and well-known conditions to acid (XII), completing the synthesis with another coupling step as described in scheme 1 above.

Scheme 2 Synthesis of derivatives of type (HIb, d, e, f) and (Hc, d), with Z = N

hi case of Z = CH, structure (HIb, d, e, f) and (Hc, d) type compounds can easily be synthesized following a protocol outlined in scheme 3, wherein a heterocycle (XIII) is converted to compound (XV) by a cyclokondensation step. After saponification, (XVI) is coupled with an amine to yield the desired product (HIb, d, e, f) or (Hc, d).

Compounds of the present invention carrying a piperidin-4-yl substituent in the 2-position of the thiazole ring can, for example, be prepared as shown in the following scheme. This synthetic route is partially described in WO 2004/058750.

2-(l-(tert-butoxycarbonyl)piperidin-4-yl)thiazole-4-carboxyl ic acid can be converted to the appropriate R ¹ amide by coupling with HBTU, DIPEA in DMF. The different R ¹ -amines are either commercially available or can be readily synthesized. The Boc-protection group can be removed under standard conditions, such as treatment with TFA for 2 to 3 hours at 0° or with 4 N HCl in dioxane for 2 to 3 hours. The deprotected piperidinoderivative HCl salt can then be converted to the corresponding amides, ureas and N-heterocyclic analogs as follows.

Urea substituted piperidino compounds can be synthesized by coupling with commercially available isocyanates in the presence of DIPEA. Piperidino compounds substituted with heterocycles can be synthesized by standard procedures, such as coupling with the corresponding chloroheterocycle in the presence of a base. Alternatively, piperidino compounds substituted with heterocycles can be obtained by palladium-mediated cross coupling. As a further alternative, hydroxypyridine derivatives can be coupled to the piperidino compound by the HBTU coupling method.

An alternative route to compounds of the present invention carrying a piperidin-4-yi substituent in the 2-position of the thiazole ring is shown in the following scheme.

The Boc-protection group can be removed under standard conditions, such as treatment with TFA for 2 to 3 hours at 0° or with 4 N HCl in dioxane for 2 to 3 hours. The deprotected piperidinoderivative HCl salt can then be converted to the corresponding N- heterocyclic analog by various methods as described as described above.

For the compounds of the formula (Ia), (Ib), (Ic), (Ih), (II), or (III) above, the term "stereoisomer" means cis/trans or E/Z isomerism.

The compounds of formula (Ia), (Ib), (Ic), (Di), (II), or (III) and their pharmacologically acceptable salts can be administered to animals, preferably to mammals, and in particular to humans, dogs and chickens as therapeutics per se, as mixtures with one another or in the form of pharmaceutical preparations which allow enteral or parenteral use and which as active constituent contain an effective dose of at least one compound of the formula (Ia), (Ib), (Ic), (Ih), (II), or (III) or a salt thereof, in addition to customary pharmaceutically innocuous excipients and additives. The compounds of formula (Ia), (Ib), (Ic), (Di), (II), or (III) can also be administered in form of their salts, which are obtainable by reacting the respective compounds with physiologically acceptable acids and bases.

The production of medicaments containing the compounds of formula (Ia), (Ib), (Ic), (Di), (II), or (III) according to the invention and their application can be performed according to well-known pharmaceutical methods.

While the compounds of formula (Ia), (Ib), (Ic), (Di), (II), or (III) according to the invention for use in therapy may be administered in the form of the raw chemical compound, it is preferred to introduce the active ingredient, optionally in the form of a physiologically acceptable salt in a pharmaceutical composition together with one or more adjuvants, excipients, carriers, buffers, diluents, and/or other customary pharmaceutical auxiliaries. Such salts of the compounds may be anhydrous or solvated.

In a preferred embodiment, the invention provides medicaments comprising compounds of formula (Ia), (Ib), (Ic), (Ih), (II), or (III) according to the invention, or a pharmaceutically

acceptable salt or pharmaceutically acceptable prodrugs or a stereoisomer thereof, together with one or more pharmaceutically acceptable carriers thereof, and. optionally, other therapeutic and/or prophylactic ingredients. The carrier(s) must be "acceptable" in the sense of being compatible with the other ingredients of the formulation and not harmful to the recipient thereof.

A medicament of the invention may be those suitable for oral, rectal, bronchial, nasal, topical, buccal, sub-lingual, transdermal, vaginal or parenteral (including cutaneous, subcutaneous, intramuscular, intraperitoneal, intravenous, intraarterial, intracerebral, intraocular injection or infusion) administration, or those in a form suitable for administration by inhalation or insufflation, including powders and liquid aerosol administration, or by sustained release systems. Suitable examples of sustained release systems include semipermeable matrices of solid hydrophobic polymers containing the compound of the invention, which matrices may be in form of shaped articles, e.g. films or microcapsules.

The compounds according to the invention, together with a conventional adjuvant, carrier, or diluent, may thus be placed into the form of medicament and unit dosages thereof. Such forms include solids, and in particular tablets, filled capsules, powder and pellet forms, and liquids, in particular aqueous or non-aqueous solutions, suspensions, emulsions, elixirs, and capsules filled with the same, all for oral use, suppositories for rectal administration, and sterile injectable solutions for parenteral use. Such Medicament and unit dosage forms thereof may comprise conventional ingredients in conventional proportions, with or without additional active compounds or principles, and such unit dosage forms may contain any suitable effective amount of the active ingredient commensurate with the intended daily dosage range to be employed.

The compound useable according to the invention can be administered in a wide variety of oral and parenteral dosage forms. It will be obvious to those skilled in the art that the following dosage forms may comprise, as the active component, either a compound of formula (Ia), (Ib), (Ic), (Ih), (II), or (III) according to the invention or a pharmaceutically acceptable salt or stereosomer thereof.

For preparing a medicament from a compounds of formula (Ia), (Ib), (Ic), (Ih), (II), or (III) pharmaceutically acceptable carriers can be either solid or liquid. Solid form preparations include powders, tablets, pills, capsules, cachets, suppositories, and dispersible granules. A solid carrier can be one or more substances which may also act as diluents, flavouring agents, solubilizers, lubricants, suspending agents, binders, preservatives, tablet disintegrating agents, or an encapsulating material.

In powders, the carrier is a finely divided solid which is in a mixture with the finely divided active component. In tablets, the active component is mixed with the carrier having the necessary binding capacity in suitable proportions and compacted in the shape and size desired. Suitable carriers are magnesium carbonate, magnesium stearate, talc, sugar, lactose, pectin, dextrin, starch, gelatin, tragacanth, methylcellulose, sodium carboxymethylcellulose, a low melting wax, cocoa butter, and the like. The term "preparation" is intended to include the formulation of the active compound with encapsulating material as carrier providing a capsule in which the active component, with or without carriers, is surrounded by a carrier, which is thus in association with it. Similarly, cachets and lozenges are included. Tablets, powders, capsules, pills, cachets, and lozenges can be used as solid forms suitable for oral administration.

For preparing suppositories, a low melting wax, such as a mixture of fatty acid glyceride or cocoa butter, is first melted and the active component is dispersed homogeneously therein, as by stirring. The molten homogenous mixture is then poured into convenient sized moulds, allowed to cool, and thereby to solidify. Compositions suitable for vaginal administration may be presented as pessaries, tampons, creams, gels, pastes, foams or sprays containing in addition to the active ingredient such carriers as are known in the art to be appropriate. Liquid preparations include solutions, suspensions, and emulsions, for example, water or water-propylene glycol solutions. For example, parenteral injection liquid preparations can be formulated as solutions in aqueous polyethylene glycol solution.

The compounds of formula (Ia), (Ib), (Ic), (Di), (II), or (III) according to the present invention may thus be formulated for parenteral administration (e.g. by injection, for example bolus injection or continuous infusion) and may be presented in unit dose form in ampoules, pre-filled syringes, small volume infusion or in multi-dose containers with an

added preservative. The compositions may take such forms as suspensions, solutions, or emulsions in oily or aqueous vehicles, and may contain formulation agents such as suspending, stabilising and/or dispersing agents. Alternatively, the active ingredient may be in powder form, obtained by aseptic isolation of sterile solid or by lyophilization from solution, for constitution with a suitable vehicle, e.g. sterile, pyrogen-free water, before use.

Aqueous solutions suitable for oral use can be prepared by dissolving the active component in water and adding suitable colorants, flavours, stabilising and thickening agents, as desired. Aqueous suspensions suitable for oral use can be made by dispersing the finely divided active component in water with viscous material, such as natural or synthetic gums, resins, methylcellulose, sodium carboxymethylcellulose, or other well known suspending agents.

Also included are solid form preparations which are intended to be converted, shortly before use, to liquid form preparations for oral administration. Such liquid forms include solutions, suspensions, and emulsions. These preparations may contain, in addition to the active component, colorants, flavours, stabilisers, buffers, artificial and natural sweeteners, dispersants, thickeners, solubilizing agents, and the like.

hi one embodiment of the present invention, the medicament is applied topically or systemically or via a combination of the two routes.

In an especially preferred embodiment of the present invention the medicament is applied topically. This reduces possible side effects and limits the necessary treatment to those areas affected.

Preferably the medicament is prepared in form of an ointment, a gel, a plaster, an emulsion, a lotion, a foam, a cream of a mixed phase or amphiphilic emulsion system (oil/water-water/oil mixed phase), a liposome, a transfersome, a paste or a powder.

Ointments and creams may, for example, be formulated with an aqueous or oily base with the addition of suitable thickening and/or gelling agents. Lotions may be formulated with

an aqueous or oily base and will in general also contain one or more emulsifying agents, stabilising agents, dispersing agents, suspending agents, thickening agents, or colouring agents.

Compositions suitable for topical administration in the mouth include lozenges comprising the active agent in a flavoured base, usually sucrose and acacia or tragacanth; pastilles comprising the active ingredient in an inert base such as gelatin and glycerine or sucrose and acacia; and mouthwashes comprising the active ingredient in a suitable liquid carrier.

Solutions or suspensions are applied directly to the nasal cavity by conventional means, for example with a dropper, pipette or spray. The compositions may be provided in single or multi-dose form. In the latter case of a dropper or pipette, this may be achieved by the patient administering an appropriate, predetermined volume of the solution or suspension. In the case of a spray, this may be achieved for example by means of a metering atomising spray pump.

Administration to the respiratory tract may also be achieved by means of an aerosol formulation in which the active ingredient is provided in a pressurised pack with a suitable propellant such as a chlorofluorocarbon (CFC) for example dichlorodifluoromethane, trichlorofluoromethane, or dichlorotetrafluoroethane, carbon dioxide, or other suitable gas. The aerosol may conveniently also contain a surfactant such as lecithin. The dose of drug may be controlled by provision of a metered valve.

Alternatively the active ingredients may be provided in the form of a dry powder, for example a powder mix of the compound in a suitable powder base such as lactose, starch, starch derivatives such as hydroxypropylmethyl cellulose and polyvinylpyrrolidone (PVP).

Conveniently the powder carrier will form a gel in the nasal cavity The powder composition may be presented in unit dose form for example in capsules or cartridges of, e.g., gelatin, or blister packs from which the powder may be administered by means of an inhaler.

In compositions intended for administration to the respiratory tract, including intranasal compositions, the compound will generally have a small particle size for example of the

order of 5 microns or less. Such a particle size may be obtained by means known in the art, for example by micronization.

When desired, compositions adapted to give sustained release of the active ingredient may be employed.

The pharmaceutical preparations are preferably in unit dosage forms. In such form, the preparation is subdivided into unit doses containing appropriate quantities of the active component. The unit dosage form can be a packaged preparation, the package containing discrete quantities of preparation, such as packaged tablets, capsules, and powders in vials or ampoules. Also, the unit dosage form can be a capsule, tablet, cachet, or lozenge itself, or it can be the appropriate number of any of these in packaged form. Tablets or capsules for oral administration and liquids for intravenous administration and continuous infusion are preferred compositions.

Further details on techniques for formulation and administration may be found in the latest edition of Remington's Pharmaceutical Sciences (Maack Publishing Co. Easton, Pa.).

Pharmaceutical compositions can also contain two or more compounds of the formula (Ia), (Ib), (Ic), (Ih), (II), or (III) or their pharmacologically acceptable salts and also other therapeutically active substances.

Thus, the compounds of the present invention can be used in the form of one compound alone or in combination with other active compounds - for example with medicaments already known for the treatment of the aforementioned diseases, whereby in the latter case a favorable additive, amplifying effect is noticed. Suitable amounts to be administered to humans may range from 5 to 500 mg.

To prepare the pharmaceutical preparations, pharmaceutically inert inorganic or organic excipients can be used. To prepare pills, tablets, coated tablets and hard gelatin capsules, for example, lactose, corn starch or derivatives thereof, talc, stearic acid or its salts, etc. can be used. Excipients for soft gelatin capsules and suppositories are, for example, fats, waxes, semi-solid and liquid polyols, natural or hardened oils etc. Suitable excipients for

the production of solutions and syrups are, for example, water, sucrose, invert sugar, glucose, polyols etc. Suitable excipients for the production of injection solutions are, for example, water, alcohols, glycerol, polyols or vegetable oils.

The dose can vary within wide limits and is to be suited to the individual conditions in each individual case. For the above uses the appropriate dosage will vary depending on the mode of administration, the particular condition to be treated and the effect desired. In general, however, satisfactory results are achieved at dosage rates of about 1 to 100 mg/kg animal body weight preferably 1 to 50 mg/kg. In general, suitable dosage rates for larger mammals, for example humans, may be of the order of from about 10 mg to 3 g/day, conveniently administered once, in divided doses 2 to 4 times a day, or in sustained release form.

In general, a daily dose of approximately 10 mg to 5000 mg, preferably 50 to 500 mg, per human individual is appropriate in the case of the oral administration. In the case of other administration forms too, the daily dose is in similar ranges. For topical delivery, depending on the permeability of the skin, the type and the severity of the disease and dependent on the type of formulation and frequency of application, different concentrations of active compounds within the medicament can be sufficient to elicit a therapeutic effect by topical application. Preferably the concentration of an active compound or a pharmaceutically acceptable salt thereof or a physiologically functional derivative or a stereoisomer thereof within a medicament according to the invention is in the range of between 1 μmol/1 and 100 mmol/1.

Proteasome assay:

The chymotryptic activity of the 2OS proteasome (Immatics, Tubingen) was determined using a Tecan Ultra plate reader and Suc-LL VT-AMC as substrate (Bachem). In the wells of a black 96 well polypropylene plate, 2 μl of the respective inhibitor dissolved in DMSO were mixed with 50 μl substrate solution (25 mM HEPES pH 7.5 at 2O ⁰ C, 0.5 mM EDTA and Suc-LL VT- AMC (in the appropriate concentration) and the reaction was initiated by adding 150 μl proteasome solution (1.3 μg/ml 2OS proteasome in 25 mM HEPES pH 7.5 at 20°C, 0.5 mM EDTA, 0.033% (w/v) SDS). Substrate hydrolysis was followed by fluorescence spectroscopy (excitation wavelength: 360 nm; emission wavelength: 465 nm) for 20 min at 30 ⁰ C and initial velocities were calculated and expressed as change in relative fluorescence units (RFU) per second.

For the determination of the IC ₅₀ values (concentration of inhibitor required for 50% inhibition) at least four different inhibitor concentrations were applied. Each data point was recorded in triplicates. Curves were fitted with the a suitable program.

T-Lymphocyte Proliferation Assay:

Inhibition of stimulated peripheral blood monocytes (PBMC).

PBMCs were isolated from the blood of healthy volunteers with the help of ACCUSPIN™ System Histopaque ^® -1077 tubes, washed and resuspended with 10 ⁶ cells/ml in Dulbecco's modified eagles medium, containing 10 % fetal calf serum and 2 mM glutamine. The cells were stimulated with 2 μg/ml phytohemoagglutinin in the presence of test compound or blank vehicle for 72 h. 4 h prior to the end of the incubation period, 5-bromo-2'- desoxyuridine (BrdU) was added to label the proliferating cells. After the incubation, the cells were separated by centrifugation and the culture supernatant removed. Incorporated

BrdU was quantified with the help of an enzyme-linked immunosorbent assay. For the determination of the IC ₅₀ values (concentration of inhibitor required for 50% inhibition) at least four different inhibitor concentrations were applied. Each data point was recorded in triplicates. Curves were fitted with the a suitable program. Based on results obtained in the T-lymphocyte proliferation assay, the compounds of the present invention are suitable for treating inflammatory diseases or diseases associated with T-cells.

Inhibition of NF-κB-induced inflammation: For the determination of anti-inflammatory activity of the compounds the PRINCESS® NINA Instant Assay from Cell Culture Service GmBH was used. This assay is based on recombinant A549-NF-KB-SEAP reporter cells preseeded in 96-well flat bottom plates. As the transfected reporter gene for SEAP (secreted embryonic alkaline phosphatase) is under transcriptional control of a NF-κB-responsive element, the expression of this reporter is activated upon stimulation with TNF-α. SEAP secretion into the culture supernatant can be detected by the chemiluminescent substrate CSPD®. Test compounds that inhibit the NF- KB activation show reduced SEAP activity and reduced luminescent readout. Following 18 h of reactivation at 37 °C, 5 % CO ₂ and 90 % relative humidity, the cells were incubated with 0.01 up to 100 μM of test compound for 4.5 h before stimulation with 2ng/ml TNF-α. After stimulation with TNF-α for 22 h endogenous phosphatases were inactivated and CSPD® substrate was supplied for 40 min. SEAP activity then was quantified by measuring luminescence as relative light units (RLU) using a Tecan Ultra reader. Each data point was recorded in quadruplicates and EC50 values were calculated via fitting function and the Microsoft Excel Solver.
