JNK Inhibitors for Treatment of Skin Diseases

FIELD OF THE INVENTION

The present invention is in the field of skin inflammation. In particular, the invention relates to the use of JNK inhibitors in preventing and/or treating skin diseases, in particular inflammatory skin diseases and psoriasis

BACKGROUND OF THE INVENTION

Skin inflammation or inflammatory skin conditions/disorders are generally characterized histologically by epidermal edema and clinically by vesicles (when acute), poorly marginated redness, edema (swelling), oozing, crusting, scaling, usually pruritus, and lichenification caused by scratching or rubbing. Skin inflammation related disorders include, but are not limited to psoriasis, eczema, burning and dermatitis. Skin inflammation related disorders may be contact hypersensitivity disorders such as contact dermatitis, wherein acute or chronic inflammation is produced by substances contacting the skin and causing toxic (irritant) or allergic reactions.

Psoriasis

Psoriasis is an inflammatory skin disorder that affects between 1 and 2% of the population. It is a common chronic, recurrent disease characterised by an increased proliferation of the epidermis, and presents as well-defined thickened erythematous patches of various sizes typically covered with a silver scale.

Psoriasis varies in severity from one or two lesions to widespread dermatosis, sometimes associated with disabling arthritis or exfoliation. The cause is unknown, but the thick scaling has traditionally been attributed to increased epidermal cell proliferation and concomitant dermal inflammation. The response of psoriasis to the immunosuppressive drug cyclosporine suggests that the primary pathogenetic factor may be immunologic. Onset is usually between ages 10 and 40, but no age is exempt. A family history of psoriasis is common. Except for the psychologic stigma of an unsightly skin disease, general health is unaffected unless psoriatic arthritis, erythrodermic psoriasis, or pustular psoriasis develops.

Psoriatic arthritis (PsA), an inflammatory arthritis and the most serious disorder associated with psoriasis, affects an estimated 25% of patients with psoriasis. PsA typically involves the distal interphalangeal joints. Current therapies for psoriasis and PsA are unsatisfactory, as none are curative; moreover, the most effective agents are associated with potentially serious side effects. In all cases, psoriasis is a chronic condition that requires long-term medication.

Erythrodermic psoriasis (exfoliative psoriatic dermatitis) may be refractory to therapy. The entire cutaneous surface is red and covered with fine scales; typical psoriatic lesions may be obscured or absent. It may lead to general debility and a need for hospitalization.

Pustular psoriasis is characterized by sterile pustules and may be generalized (von Zumbusch type) or localized to the palms and soles (Barber's psoriasis); typical psoriatic lesions may be absent.

Although the aetiology and pathology of psoriasis is not well understood, the discovery that T-cells and inflammatory cytokines are centrally involved in the development of psoriasis and is leading to the development of new biological therapeutic agents to treat these conditions.

Present treatments for psoriasis, consisting of drug therapies and phototherapies, may clear lesions and relieve uncomfortable symptoms of the disease, but remissions are usually short-lived and most patients experience at least one exacerbation or relapse per year.

Topical therapies are often the initial therapeutic choice for mild-to-moderate psoriasis. Emollients and moisturisers are the first choice because they cause few side effects; they are also often used as pre-treatments for, or in combination with, other active topical agents. Keratolytic agents act by reducing hyperkeratosis and softening psoriatic scales, aiding in their removal. As with emollients, keratolytic agents are often used to supplement other therapies.

Corticosteroids are the most common treatment for psoriasis. Numerous forms of corticosteroids are available, depending on the required potency. Systemic absorption of very potent corticosteroids can cause skin atrophy, and abrupt withdrawal can cause the disease to flare. The relapse rate has been reported to vary from 35-80%, depending on the formulation and treatment regimen used.

Topical retinoids (vitamin A analogues) work by interacting with receptors that regulate gene expression within the cell, i.e., the fundamental mechanism of cell growth and differentiation. They are applied only once daily and approximately 50-60% of patients will achieve a good response after 12 weeks of treatment. The efficacy of topical retinoids can be enhanced with concomitant high-potency corticosteroids.

Systemic therapies are frequently the therapeutic choice for moderate-to-severe psoriasis. They include phototherapy, retinoids, methotrexate and immunosuppressive drugs such as cyclosporin.

Phototherapy with ultraviolet A or B light (PUVA or PUVB) is thought to block DNA replication, thereby decreasing skin proliferation. Phototherapy with UVA, has been shown to be effective; however, its use is associated with the development of skin cancer, and is therefore limited to carefully selected patients with extensively disabling psoriasis and to those over 50 years of age.

The use of systemic retinoids is mainly limited to the treatment of severe and less common forms of psoriasis. These drugs are anti-inflammatory agents that decrease skin proliferation. However, their use is associated with severe side effects, which include liver damage and foetal abnormalities.

Methotrexate is a folic acid analogue that inhibits DNA synthesis, thus stopping rapid cell division, such as that found in untreated psoriatic lesions. Oral methotrexate is the most effective treatment in severe disabling psoriasis, especially severe psoriatic arthritis or widespread erythrodermic or pustular psoriasis unresponsive to topical agents or PUVA. It is generally reserved for very severe and refractory psoriasis, as its use is associated with liver toxicity.

Immunosuppressive drugs such as cyclosporin function by inhibiting T-cells. Cyclosporin is generally used for severe plaque psoriasis; however, its use is limited to refractory patients because of its side effects, which include renal toxicity, paraesthesia and hirsutism.

Cyclosporine is extremely effective but it has potentially serious systemic side effects.

The humanized anti-CD11a antibody efalizumab or Raptiva® received marketing approval from the FDA in 2003 for the treatment for the treatment of psoriasis. It is an immunosuppressive agent that has the potential to increase the risk of infection and reactivate latent, chronic infections.

Dermatitis

Dermatitis is also called eczema. It relates to a superficial skin inflammation, characterized histologically by epidermal edema and clinically by vesicles (when acute), poorly marginated redness, edema, oozing, crusting, scaling, usually pruritus, and lichenification caused by scratching or rubbing.

Often, eczema refers to vesicular dermatitis, but sometimes the term is restricted eczema to mean chronic dermatitis. Some also refer to dermatitis as spongiotic dermatitis because spongiosis (intraepidermal edema) is a histologic feature.

Contact Dermatitis is an acute or chronic inflammation, often asymmetric or oddly shaped, produced by substances contacting the skin and causing toxic (irritant) or allergic reactions. It may be caused by a primary chemical irritant or by an allergen (ie, a type IV delayed hypersensitivity reaction).

Primary irritants may damage normal skin or irritate existing dermatitis. Clinically recognizable changes may occur within minutes of exposure to strong irritants (eg, acids, alkalis, phenol) or may take up to several days' exposure to weak or marginal irritants (eg, soap, detergents, acetone, or even water). The mechanisms by which these irritants damage the skin are different for different agents. For example, detergents activate keratinocytes, causing them to release inflammatory cytokines.

Allergic contact dermatitis patients may become allergic to substances that they have sometimes used for years or to drugs used to treat skin diseases. Allergens are captured by Langerhans' cells (a minor subpopulation of epidermal cells), which present them to T cells. Cytokines released from keratinocytes and Langerhans' cells may also contribute to sensitivity induction. It takes between 6 and 10 days (in the case of strong sensitizers, eg, poison ivy) to years (for weaker sensitizers) for patients to become sensitized. On reexposure to the sensitizer, patients may develop pruritus and dermatitis within 4 to 12 h.

Photoallergic and phototoxic contact dermatitides require exposure to light after topical application of certain chemicals. The chemicals (phototoxins) produce an exaggerated response to sunlight by acting as photosensitizers (see polymorphous light eruptions under Photosensitivity in Ch. 119). Aftershave lotions, sunscreens, and topical sulfonamides are commonly responsible for photoallergic contact dermatitis. Phototoxic contact dermatitis is commonly caused by certain perfumes, coal tar, psoralens, and oils used in manufacturing. Photoallergic and phototoxic contact dermatitides must be differentiated from photosensitivity reactions to systemic drugs.

Contact dermatitis ranges from transient redness to severe swelling with bullae pruritus and vesiculation are common. Any skin surface exposed to an irritant or sensitizing substance (including airborne ones) may be involved. Typically, the dermatitis is limited to the site of contact but may later spread.

The course varies. If the causative agent is removed, erythema disappears within a few days to weeks and blisters dry up. Vesicles and bullae may rupture, ooze, and crust. As inflammation subsides, scaling and some temporary thickening of the skin occur. Continued exposure to the causative agent or complications (eg, irritation from or allergy to a topical drug, excoriation, infection) may perpetuate the dermatitis.

Unless the causative agent is identified and removed, treatment may be ineffective. An oral corticosteroid may be given (if not contraindicated). Antihistamines are ineffective in suppressing allergic contact dermatitis but may blunt the itching.

c-Jun N-Terminal Kinases (JNKs)

Mammalian cells respond to some extracellular stimuli by activating signaling cascades which are mediated by various mitogen-activated protein kinases (MAPKs). Despite the differences in their response to upstream stimuli, the MAP kinase cascades are organized in a similar fashion, consisting of MAP kinase kinase kinases (MAPKKK or MEKK), MAP kinase kinases (MAPKK or MKK) and MAP kinases (MAPK). MAP kinases are a broad family of kinases, which includes c-Jun N-Terminal kinases (JNKs), also known as “stress-activated protein kinases” (SAPKs), as well as extracellular signal regulated kinases (ERKs) and p38 MAP kinases. Each of these three MAP kinases sub-families is involved in at least three different but parallel pathways conveying the information triggered by external stimuli. The JNK signaling pathway is activated by exposure of cells to environmental stress—such as chemical toxins, radiation, hypoxia and osmotic shock—as well as by treatment of cells with growth factors or pro-inflammatory cytokines—such as tumour necrosis factor alpha (TNF-α) or interleukin-1 beta (IL-1β).

Two MAP kinase kinases (known as MKKs or MAPKKs), i.e. MKK4 (known also as JNKK1) and MKK7, activate JNK by a dual phosphorylation of specific threonine and tyrosine residues located within a Thr-Pro-Tyr motif on the activation loop on the enzyme, in response to cytokines and stress signals. Even further upstream in the signaling cascade, MKK4 is known to be activated itself also by a MAP kinase kinase kinase, MEKK1 through phosphorylation at serine and threonine residues.

Once activated, JNK binds to the N-terminal region of transcription factor targets and phosphorylates the transcriptional activation domains resulting in the up-regulation of expression of various gene products, which can lead to apoptosis, inflammatory responses or oncogenic processes (Davis, 2000).

Some transcription factors known to be JNK substrates are the Jun proteins (c-jun, JunB and Jun D), the related transcription factors ATF2 and ATFa, Ets transcription factors such as Elk-1 and Sap-1, the tumor suppressor p53 and a cell death domain protein (DENN).

Three distinct JNK enzymes have been identified as products of the genes JNK1, JNK2 and JNK3 and ten different isoforms of JNK have been identified (Gupta et al., 1996). JNK1 and -2 are ubiquitously expressed in human tissues, whereas JNK3 is selectively expressed in the brain, heart and testes (2). Each isoform binds to the substrates with different affinities, suggesting, in vivo, a substrate specific regulation of the signaling pathways by the different JNK isoforms.

Activation of the JNK pathway has been documented in a number of disease processes, thus providing a rationale for targeting this pathway for drug discovery. In addition, molecular genetic approaches have validated the pathogenic role of this pathway in several diseases.

For example, auto-immune and inflammatory diseases derive from the inappropriate activation of the immune system. Activated immune cells express many genes encoding inflammatory molecules, including cytokines, growth factors, cell surface receptors, cell adhesion molecules and degradative enzymes. Many of these genes are known to be regulated by the JNK pathway, through the activation of the transcription factors c-Jun and ATF-2.

The inhibition of JNK activation in bacterial lipopolysaccharide-stimulated macrophages, effectively modulates the production of the key pro-inflammatory cytokine, TNFα (Dumitru et al., 2000).

The inhibition of JNK activation decreases the transcription factor activation responsible of the inducible expression of matrix metalloproteinases (MMPs) (Han et al., 2001), which are known to be responsible of the promotion of cartilage and bone erosion in rheumatoid arthritis and of generalized tissue destruction in other auto-immune diseases.

The JNK cascade is also activated in T cells by antigen stimulation and CD28 receptor co-stimulation (Nishina et al., 1997) and regulates the production of the IL-2 promoter (Kempiak et al., 1999). Inappropriate activation of T lymphocytes initiates and perpetuates many auto-immune diseases, including asthma, inflammatory bowel syndrome and multiple sclerosis.

In neurons vulnerable to damage from Alzheimer's disease and in CA1 neurons of patients with acute hypoxia (de la Monte et al., 2000), JNK3 protein is highly expressed. The JNK3 gene was also found to be expressed in the damaged regions of the brains of Alzheimer's patients (Zhu et al., 2001). In addition, neurons from JNK3 KO mice were found to become resistant to kainic acid induced neuronal apoptosis compared to neurons from wild-type mice.

ERK and JNK were shown to be activated in a tissue culture of psoriatic involved epidermis (Takahashi et al., 2002). However, from these in vitro data, a medical utility of JNK inhibition in psoriasis cannot be predicted

Several small molecules have been proposed as modulators of the JNK pathway.

Pyrazoloanthrones derivatives of formula (C) have been reported to inhibit JNK for the treatment of neurological degenerative diseases, inflammatory and autoimmune disorders as well as cardiovascular pathologies (WO 01/12609).

Tetrahydro-pyrimidine derivatives of formula (D) were reported to be JNK inhibitors useful in the treatment of a wide range of diseases including neurodegenerative diseases, inflammatory and autoimmune disorders, cardiac and destructive bone pathologies (WO 00/75118).

Other heterocyclic compounds of formula (E) have been proposed to inhibit protein kinases and especially c-un-N-Terminal kinases (WO 01/12621) for treating “JNK-mediated conditions” including proliferative diseases, neurodegenerative disorders, inflammatory and autoimmune disorders.

Benzazoles derivatives such as represented by formula (F) have been described as modulators of the JNK pathway for the treatment of neuronal disorders, autoimmune diseases, cancers, cardiovascular diseases (WO 01/47920, EP110957) and scleroderma (WO 03/047570) The use of similar compounds in combination with cyclosporin has been described for the treatment of a neuronal disorder, an autoimmune disease, an inflammatory disorder, cancer or a cardiovascular disease (WO 2005/097116).

Several sulfonamide derivatives of formula (G) (WO 01/23378), sulfonyl amino acid derivatives of formula (H) (WO 01/23379) and sulfonyl hydrazide derivatives of formula (J) (WO 01/23382), were also developed to inhibit JNKs for treating neurodegenerative diseases, autoimmune disorders, cancers and cardiovascular diseases.

“JNK” means a protein or an isoform thereof expressed by a JNK 1, JNK 2, or JNK 3 gene (Gupta et al. 1996).

“JNK-inhibitor” refers to a compound, a peptide or a protein that inhibits c-jun amino terminal kinase (JNK) phosphorylation of a JNK targeted transcription factor. The JNK-inhibitor is an agent capable of inhibiting the activity of JNK in vitro or in vivo. Such inhibitory activity can be determined by an assay or an animal model well-known in the art.

In the frame of the present invention it has been found that the administration of a JNK inhibitor has a beneficial effect in an animal model of psoriasis and allergic dermatitis.

The invention therefore relates to the use of a therapeutically effective amount of a JNK inhibitor for the manufacture of a medicament for treating and/or preventing a skin disease.

The terms “treating” and “preventing”, as used herein, should be understood as preventing, inhibiting, attenuating, ameliorating or reversing one or more symptoms or cause(s) of skin diseases, as well as symptoms, diseases or complications accompanying skin disease. When “treating” skin disease, the substances according to the invention are given after onset of the disease, “prevention” relates to administration of the substances before signs of disease can be noted in the patient.

In a preferred embodiment of the invention, the skin disease is an inflammatory skin disease.

Skin inflammation or inflammatory skin diseases are generally characterized histologically by epidermal edema and clinically by vesicles (when acute), poorly marginated redness, edema (swelling), oozing, crusting, scaling, usually pruritus, and lichenification caused by scratching or rubbing. Skin inflammation related disorders include, but are not limited to psoriasis, eczema, burning and dermatitis. Skin inflammation related disorders may be contact hypersensitivity disorders such as contact dermatitis, wherein acute or chronic inflammation is produced by substances contacting the skin and causing toxic (irritant) or allergic reactions.

In a further preferred embodiment of the invention, the skin disease is psoriasis.

“Psoriasis” refers to psoriasis in any classification and definition, as well as one or more of the symptoms of scleroderma. Psoriasis is an inflammatory skin disorder. It is a common chronic, recurrent disease characterised by an increased proliferation of the epidermis. Psoriasis is discussed in more details in the “Background of the invention” above.

In a further preferred embodiment, the skin disease is dermatitis in particular allergic dermatitis or allergic contact dermatitis.

“Allergic dermatitis” or allergic contact dermatitis is an itchy skin condition caused by an allergic reaction to material in contact with the skin. Dermatitis is discussed in more details in the “Background of the invention” above.

A “therapeutically effective amount” is such that when administered, the JNK inhibitor results in inhibition of the biological activity of JNK. The dosage administered, as single or multiple doses, to an individual will vary depending upon a variety of factor, including JNK inhibitor pharmacokinetic properties, the route of administration, patient conditions and characteristics (sex, age, body weight, health, size), extent of symptoms, concurrent treatments, frequency of treatment and the effect desired. Adjustment and manipulation of established dosage ranges are well within the ability of those skilled, as well as in vitro and in vivo methods of determining the inhibition of JNK in an individual.

The compounds of formula (III) may be obtained according to the methods described in any of WO 01/23378, WO 02/28856 and WO 02/26733.

In a further embodiment the JNK inhibitors may be a pyrazoloanthrone derivative as shown in formula (C) (WO 01/12609):

In a further embodiment the JNK inhibitors may have the formula (IV) (WO 03/018022):

The invention further relates to pharmaceutical compositions, particularly useful for prevention and/or treatment of skin diseases, preferably skin inflammatory skin diseases and more preferably psoriasis, which comprise a therapeutically effective amount of JNK inhibitor and a pharmaceutical excipient.

The invention also relates to a method of treatment comprising administering to a patient in need thereof a therapeutically effective amount of a JNK inhibitor.

The pharmaceutical compositions of the present invention can be administered by a variety of routes including oral, rectal, transdermal, subcutaneous, intravenous, intramuscular and intranasal. The compositions for oral administration can take the form of bulk liquid solutions or suspensions, or bulk powders. More commonly, however, the compositions are presented in unit dosage forms to facilitate accurate dosing. The term “unit dosage forms” refers to physically discrete units suitable as unitary dosages for human subjects and other mammals, each unit containing a predetermined quantity of active material calculated to produce the desired therapeutic effect, in association with a suitable pharmaceutical excipient. Typical unit dosage forms include prefilled, premeasured ampoules or syringes of the liquid compositions or pills, tablets, capsules or the like in the case of solid compositions. In such compositions, the JNK inhibitor is usually a minor component (from about 0.1 to about 50% by weight or preferably from about 1 to about 40% by weight) with the remainder being various vehicles or carriers and processing aids helpful for forming the desired dosing form.

The route of administration, which is preferred according to the invention is administration by oral route.

Liquid forms suitable for oral administration may include a suitable aqueous or nonaqueous vehicle with buffers, suspending and dispensing agents, colorants, flavors and the like.

Solid forms may include, for example, any of the following ingredients, or compounds of a similar nature: a binder such as microcrystalline cellulose, gum tragacanth or gelatine; an excipient such as starch or lactose, a disintegrating agent such as alginic acid, Primogel, or corn starch; a lubricant such as magnesium stearate; a glidant such as colloidal silicon dioxide; a sweetening agent such as sucrose or saccharin; or a flavoring agent such as pepper-mint, methyl salicylate, or orange flavoring.

Injectable compositions are typically based upon injectable sterile saline or phosphate-buffered saline or other injectable carriers known in the art. As above-mentioned, the JNK inhibitor in such compositions is typically a minor component, frequently ranging between 0.05 to 10% by weight with the remainder being the injectable carrier and the like.

The above-described components for orally administered or injectable compositions are merely representative. Further materials as well as processing techniques and the like are set out in Part 5 of Remington's Pharmaceutical Sciences, 20^thEdition, 2000, Marck Publishing Company, Easton, Pa., which is incorporated herein by reference.

The compounds of this invention can also be administered in sustained release forms or from sustained release drug delivery systems. A description of representative sustained release materials can also be found in the incorporated materials in Remington's Pharmaceutical Sciences.

The definition of “pharmaceutically acceptable” is meant to encompass any carrier, which does not interfere with effectiveness of the biological activity of the active ingredient and that is not toxic to the host to which it is administered. For example, for parenteral administration, JNK inhibitor may be formulated in a unit dosage form for injection in vehicles such as saline, dextrose solution, serum albumin and Ringer's solution.

For parenteral (e.g. intravenous, subcutaneous, intramuscular) administration, JNK inhibitors can be formulated as a solution, suspension, emulsion or lyophilized powder in association with a pharmaceutically acceptable parenteral vehicle (e.g. water, saline, dextrose solution) and additives that maintain isotonicity (e.g. mannitol) or chemical stability (e.g. preservatives and buffers). The formulation is sterilized by commonly used techniques.

The therapeutically effective amounts of a JNK inhibitor will be a function of many variables, including the type of inhibitor, the affinity of the inhibitor for JNK, any residual cytotoxic activity exhibited by the JNK inhibitor, the route of administration or the clinical condition of the patient.

It should also be understood that a specific dosage and treatment regimen for any particular patient will depend upon a variety of factors, including the activity of the specific compound employed, the age, body weight, general health, sex, diet, time of administration, rate of excretion, drug combination, and the judgment of the treating physician and the severity of the particular disease being treated. The amount of a compound of the present invention in the composition will also depend upon the particular compound in the composition.

Depending upon the particular condition, or disease, to be treated or prevented, additional therapeutic agents, which are normally administered to treat or prevent that condition, may also be present in the compositions of this invention. As used herein, additional therapeutic agents that are normally administered to treat or prevent a particular disease, or condition, are known as “appropriate for the disease, or condition, being treated”.

The dose of the JNK Inhibitor is adjusted between 10 and 100 mg/kg, preferably to 40-80 mg/kg of body weight.

In a preferred embodiment of the present invention, the JNK inhibitor is used in about 0.1 to 100 mg/kg of body weight, or about 1 to 50 mg/kg of body weight or about 5 to 10 mg/kg of body weight.

According to the invention, a JNK inhibitor can be administered prophylactically or therapeutically to an individual prior to, simultaneously or sequentially with other therapeutic regimens or agents (e.g. multiple drug regimens), in a therapeutically effective amount. Active agents that are administered simultaneously with other therapeutic agents can be administered in the same or different compositions.

Therefore, another aspect of the invention further related to a the use of a therapeutically effective amount a JNK inhibitor alone or in combination with an additional therapeutic agent selected from Methotrexate, efalizumab, Cyclosporine, Corticosteroids, Topical retinoids for the treatment of a skin disease.

A further aspect of the invention further relates to a method for treating a skin disease comprising administering to a patient in need thereof an effective amount of a JNK inhibitor optionally together with a pharmaceutically acceptable carrier.

The present invention will now be illustrated by the example, which is not intended to be limiting in any way.

Example 1
Contact Hypersensitivity Model in Mice (CHS)
Introduction

Contact hypersensitivity (CHS) is a T-cell mediated model of skin inflammation related disorders. The immune response is mediated by IFNγ-producing Th1/Tc1 cells and is a model of psoriasis and allergic dermatitis. In this model the hapten DNFB (dinitrofluorobenzene), which induces a type-1 cytokine response was used.

Psoriatic skin shows markedly increased keratinocyte proliferation and altered differentiation with various abnormal signaling pathways. Immunohistochemical and Western blot analyses studies showed increased mitogen activated kinases (MAPKs) expression in the nuclei of psoriatic patients epidermis. Since alterations in specific signal transduction pathways may explain the hyperproliferation and abnormal keratinocytes differentiation as well as the increased expression of inflammatory cytokines seen in skin diseases, was investigated the Contact hypersensitivity model (CHS) signaling and cytokine release during a time course.

Materials and Method

Balb/C female mice of about 8-12 weeks of age (18-22 g b.w.) were used for the Contact Hypersensitivity model. They were from Charles River Italia (Calco, Italy) and housed under the following constant environmental conditions: temperature 22° C.±2, relative humidity 55%±10, 15-20 air changes per hour (filtered on HEPA 99.99%) and artificial light with a 12-hour circadian cycle (7 a.m.-7 p.m.). All in vivo studies were performed according to the European Council Directive 86/609/EEC and the Italian Ministry guidelines for the care and use of experimental animals (decree #116/92). All the experimental protocols were authorized by the Italian Ministry of Health.

Chemicals and Reagents

All chemicals were purchased from Sigma-Aldrich (St. Louis, Mo., USA) unless otherwise specified. Antibodies used Western Blotting were obtained from Cell Signaling Technology (Beverly, Mass., USA). The JNK inhibitor 1,3-benzothiazol-2-yl(2-{[4-(morpholin-4-ylmethyl)benzyl]oxy}pyrimidin-4-yl)acetonitrile was from Serono Pharmaceutical Research Institute, Geneva, Switzerland. For the in vivo studies, the JNK inhibitor and dexamethasone were suspended in deionised water as vehicle.

Contact Hypersensitization Model (CHS)

For the induction of CHS, 8-12 weeks old Balb/C mice, were sensitized by applying once a sensitizing solution of 35 μl of 0.5% DNFB in acetone/olive oil (4:1) on the shaved back. 6 mice were used as negative control (unsensitized animals). After 5 days, sensitized and unsensitized control animals were challenged (CH) by applying 15 μl of 0.2% DNFB in acetone/olive oil (4:1) to the dorsal and ventral side of the right ear. As control, the left ear was challenged with an equal volume of vehicle (acetone/olive oil). Ear thickness was monitored using a caliper at day 0, at day 5 (4 h, 8 h), at day 6 (24 h) and at day 7 (48 h). A non-sensitized but challenged control group (n=6) was included. Ear thickness of both ears was measured at three point each, ear swelling was evaluated according to the following formula:

[(T_n−T₅)right ear]−[(T_n−T₅)left ear]

where T_nand T₅represent values of averaged ear thickness at day n of investigation and at day 5 pre challenge, respectively.

At every time point, 6 mice were sacrificed and challenged ear homogenated for cytokine detection and Western Blot analysis.

JNK Inhibitor in the Contact Hypersensitization Model (CHS)

Four groups (n=6) of mice were sensitized and 30 minutes before challenge treated respectively with vehicle (water for injection), JNK Inhibitor at 10 and 30 mg/kg p.o. and dexamethasone at 1 mg/kg s.c. as reference compound. A non-sensitized but challenged control group (n=6) was included. After 24 h mice were sacrificed and challenged ear snap frozen in liquid nitrogen and homogenated for cytokine detection and Western Blot analysis.

Cytokine Detection

Challenged ears were snap frozen, homogenated and resuspended with ice-cold lysis buffer (PBS 1×, 2% w/v SDS, 50 mM DTT). After sonication, lysates were centrifuged, protein concentration determined and 100 μg used for cytokine analysis with BD mouse CBA (Cytometric Bead Array, BD) Inflammation and Th1/Th2 kits and processed as described by the technical brochure. Samples were analysed using a FACS Calibur and Cell Quest software (BD Biosciences, San Jose, Calif., USA).

Western Blotting

Challenged ears were snap frozen, homogenated and resuspended with ice-cold lysis buffer (PBS 1×, 2% w/v SDS, 50 mM DTT). After sonication, lysates were centrifuged, protein concentration determined and 100 μg of proteins separated by electrophoresis on 10% SDS-PAGE and transferred onto a polyvinylidene difluoride-plus membrane. After blocking with 5% milk, the immunoblots were probed with a 1:1000 dilution anti phosphorylated- and total-AKT, ERK1/2, c-jun, p38MAPK, caspase-3 and cleaved caspase-3 antibody (Cell Signaling Technology) overnight at 4° C., followed by a 1 hour incubation at room temperature with the corresponding secondary antibodies. The blots were visualized with ECL-plus reagent. Phospho-immunoblots were then stripped with strip buffer at 50° C. for 30 minutes and reblotted for total protein (Cell Signaling Technology). The volume of the protein bands was quantified by a Bio-Rad ChemiDoc™ EQ densitometer and a Bio-Rad Quantity One® software (Bio-Rad Laboratories, Hercules, Calif., USA).

Statistical Analysis

All values in the text and figures are presented as mean±SEM of (n) independent experiments. All data were analysed by one-way ANOVA followed by Tukey test. P values <0.05 were considered statistically significant. S-Plus 2000 v. 4.6 statistical software was used (Mathsoft Inc., Seattle, Wash., USA).

Results
Contact Hypersensitivity Model: Ear Swelling and Cytokine Detection Time Course

Ear swelling and inflammatory cytokines presented the same trend of increase during the CHS time course. Ear thickness, IFNγ, MCP-1 and IL6 dramatically rose up (p<0.001) at 24 h and 48 h, TNFα and IL10 increased at 48 h (respectively p<0.05 and p<0.001, one-way ANOVA followed by Tukey test) (FIG. 1-2).

No variation in phosphorylation- and total-AKT, ERK and p38 MAPK along the whole time-course. On the contrary was observed that c-jun-phosphorylation status reached a peak 24 h after challenge (p<0.05) and caspase-3 cleavage was activated at 48 h after challenge. No differences in total-c-jun and caspase-3 were shown. (FIG. 3). These data suggested the pivotal role of c-jun-N terminal Kinase (JNK) in the inflammatory processes of the CHS model.

JNK Inhibitor in the Contact Hypersensitivity Model

In order to investigate the role of JNK in the CHS model, we administered 1,3-benzothiazol-2-yl(2-{[4-(morpholin-4-ylmethyl)benzyl]oxy}pyrimidin-4-yl)acetonitrile, a non JNK isoform specific inhibitor. Four groups (n=6) of mice were sensitized and 30 minutes before challenge treated respectively with vehicle (water for injection), JNK inhibitor at 10 and 30 mg/kg p.o. and dexamethasone at 1 mg/kg s.c. as reference compound. A non-sensitized but challenged control group (n=6) was included. JNK inhibitor at 30 mg/kg p.o. and dexamethasone significantly reduced ear swelling (p<0.05 and p<0.01 respectively). (FIG. 4)

This modulation can lead to therapeutic efficacy by e.g. release of soluble mediators. Extended analysis of immune responses after JNK inhibition should give insight of JNK involvement and potential therapeutic impact.
