Description:
Treatment and prevention of viral diseases with 2,3-dihydrobenzofuran-5-yl compounds BACKGROUND OF THE INVENTION

Viral infections are usually treated with substances targeting viral proteins. For example, influenza is treated with M2-membrane protein inhibitors (adamantin and rimantadin) or neuraminidase inhibitors (oseltamivir and zanamivir). HIV is treated with HIV protease inhibitors, reverse transcriptase inhibitors (nucleoside and non-nuc!eoside analoga), fusion inhibitors (blocking the viral transmembrane protein gp41 ) or cell entry inhibitors. HCV is usually treated by a combination of ribavirin and interferone alpha, where ribavirin as a nucleoside analogue inhibits the viral polymerase and interferone alpha activates the host immune system; also viral protease inhibitors and viral RNA polymerase inhibitors have been recently approved for treatment. HBV is treated with pegylated interferone alpha and/or nucleoside or nucleotide analoga. Herpes and human cytomegalovirus infections are treated with ganciclovir or structurally related substances like acyclovir and penciclovir, respectively, which also are analogs of the nuclein base guanine. However, these approaches to the treatment of viral diseases are not satisfactory due to the high mutation rate of viruses and the thus resulting lack of efficacy of presently known medications. Moreover, severe side effects caused by interaction with host factors or by incompatibility of treatments for patients who are infected with two or several different viruses occur regularly. In view of rising numbers of infections, especially with opportunistic viruses like HSV and HCMV in the background of immunocompromised patients (e.g organ transplant recipients or HIV infected persons) and taking into account the viruses' abilities to quickly adapt to new selection pressures caused by substances targeting viral proteins, new treatment options for viral diseases are urgently required. A rarely used approach to circumvent the selection pressure on viruses and thus avoid the generation of resistences is the targeting of host cell factors vital for the viral replication cycle. An example for inhibition of host: targets constitutes the small molecule CLK inhibitor TG003 ((Z)-l -(3-Ethyl-5-methoxy-2,3- dihydrobenzothiazol-2-ylidene)propan-2-one). TG003 has been tested against influenza viruses i in vitro assays and its activity was attributed to its interference with the splicing of viral M2 messanger RNA (Karlas A et al. (2010) Nature 463, 818-822). In this way, the cellular machinery required for production of virus progeny is inhibited and thus can be exploited to suppress the replication of certain viruses. However, Karlas A et al (Nature (2010) 463, 818-822) tested TG003 in a viral model and found that TG003 inhibited viral replication by about only one order of magnitude at a concentration of about 50μΜ, thus rendering this compound unsuitable for effectively treating subjects suffering from viral infections. Even a complete knockdown of CLK1 did not stop viral replication entirely. These results indicate that inhibition of CI.K 1 alone is insufficient to inhibit viral replication.

WO 2014/202638 Al describes certain compounds of the present Formula. (I) and that they interact with DYRK kinase, suggesting their applicability in prevention and/or therapy o medical conditions wherein the function o DYRK kinase plays a role.

BRIEF SUMMARY OF THE INVENTION

It has now been found that the compounds of below Formula (I) surprisingly also display activity against certain viruses. Moreover, said compounds show inhibition of viral replication, although the entire mechnism by which said inhibition is achieved is currently not known.

Suitable examples of controlled 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 or colloidal drug carriers e.g. polymeric nanoparticles, or controlled release solid dosage forms, e.g. core tablets or multi-layer tablets.

The production of medicaments or pharmaceutical compositions comprising the compounds according to the present invention and their application can be performed according to methods which are well-known to the medical practitioner.

Pharmaceutically acceptable carriers used in the preparation of a pharmaceutical composition or medicament comprising a compound according to the present invention, a pharmacologically acceptable salt or physiologically functional derivative thereof, can be either solid or liquid. Solid form pharmaceutical compositions comprising a compound according to the present invention, a pharmacological 1 y acceptable salt or physiologically functional derivative thereof, include powders, tablets, pills, capsules, sachets, suppositories, and dispersible granules. A solid carrier may comprise one or more components, 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. The tabletting mixture can be granulated, sieved and compressed or direct compressed. Suitable carriers are magnesium carbonate, magnesium stearate, talc, sugar, lactose, pectin, dextrin, starch, gelatine, tragacanth, methylcellulose, sodium carboxymcthylccllulose, 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, sachets and lozenges are included. Tablets, powders, capsules, pills, sachets, 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 conveniently sized moulds, allowed to cool, and thereby to solidify. Compositions suitable for vaginal administration may be presented as peccaries, 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- propylcnc glycol solutions. For example, parenteral injection liquid preparations can be formulated as solutions in aqueous polyethylene glycol solution. The compounds according to the present invention may 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, stabilizing 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 re-constitution with a suitable vehicle, e.g. sterile, pyrogen- free water, before use. Aqueous solutions suitable for oral administration can be prepared by dissolving the active component in water and adding for example suitable colorants, flavours, stabilizing 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 administration, 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, for example colorants, flavours, stabilizers, buffers, artificial and natural sweeteners, dispersants, thickeners, solubilizing agents, and the like.

In an embodiment f the present invention the medicament is applied topically, e.g. in the form of transdermal therapeutic systems (e.g. patches) or topical formulations (e.g. liposomes, cremes, ointment, lotion, gels, dispersion, suspension, spray, solution, foam, powder). This may be suitable to reduce possible side effects and. where appropriate, limit the necessary treatment to those areas affected.

Particularly the medicament may comprise carrier materials or excipients, including but not limited to a lipophilic phase (as for example Vaseline, paraffines, triglycerides, waxes, polyalcylsiloxanes), oils (olive oil, peanut oil. castor oil, triglyceride oil), cmulsificr (as for example lecithin, phosphat idylgl ycerol es, alkyl alcohols, sodium lauryl sulfate, polysorbats, Cholesterol, sorbitan fatty acid ester, polyoxyethylene fatty acid glycerol and -ester, poloxamers), preservatives (for instance benzalkonium chloride, chlorobutanol, parabene or fhiomersal), flavouring agents, buffer substances (for example salts of acetic acid, citric acid, boric acid, phosphoric acid, tatric acid, trometamole or trolamine), solvents (for instance po 1 yethyi eng) ycol s, glycerol, ethanol, isopropanol or propyleneglycol) or solubilizers, agents for achieving a depot effect, salts for modifying the osmotic pressure, carrier materials for patches (for instance polypropylene, ethy!ene-vinylacetat-copolymer, polyacrylates, silicon) or antioxidants (for example ascorbate, tocopherol, butylhydroxyanisole, gallic acid esters or butylhydroxytoluol). 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 fonnulated with an aqueous or oily base and will in general also contain one or more emulsifying agents, stabilizing 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 gelatine and glycerine or sucrose and acacia; and mouthwashes comprising the active ingredient in a suitable liquid carrier.

Solutions or suspensions may be 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 atomizing 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 pressurized pack with a suitable propel] ant such as a chlorofluorocarbon (CFC), for example dichlorodiftuoromcthane, trichlorofluoromethane, or dichlorotetrafluoroethane, carbon dioxide, or other suitable gas. The aerosol may conveniently also contain a surfactant such as lecithin. The dose f drug may be controlled by provision of a metered valve.

Alternatively the medicament may be provided in the form of a dry powder, for example a powder mix o 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., gelatine, or blister packs from which the powder may be administered by means of an inhaler. in compositions 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 microni/.ation.

When desired, compositions adapted to give sustained release of the active ingredient may be employed. The pharmaceutical preparations are particularly 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, sachet, 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 particular compositions.

Further details on techniques for formulation and administration may be found in the 21 st edition of Remington's Pharmaceutical Sciences (Maack Publishing Co. Easton, Pa.).

The compounds of the present invention may be used in combination with radiation therapy, or in combination with radiation therapy and other active compounds, already known for the treatment of the medical conditions disclosed herein, whereby a favourable additive or amplifying effect is noticed. To prepare the pharmaceutical preparations, pharmaceutically inert inorganic or organic excipients can be used. To prepare pills, tablets, coated tablets and hard gelatine capsules, for example, lactose, cornstarch or derivatives thereof, talc, stearic acid or its salts, etc. can be used. Excipients for soft gelatine 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 symps 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 particularly 1 to 50 mg/kg. Suitable dosage rates for larger mammals, for example humans, are of the order of from about 10 mg/day to 500 mg/day, conveniently administered once, in divided doses 2 to 4 times a day, or in sustained release form. The compounds of the present invention are suitable for the treatment or prevention of a disease or medical condition caused by a viral infection. It is apparent that the embodiments of the present invention as described herein may be combined to form further particular embodiments of the present invention.

Examples Methods for the synthesis of compounds of the present invention is known to the skilled person and described in WO 2014/202638 Al , as well as their potency in the inhibition of DYRK Kinase, and the hedgehog pathway.

Cell culture and virus: Primary human foreskin fibroblasts (HFF) were cultivated in minimal essential medium (MEM) containing 5% (vol/vol) fetal calf serum. Infection analysis was restricted to cell passage numbers below 20. HCMV strain AD 169 was grown in HFF and quantitated for infectivity by a plaque reduction assay. Aliquots were stored at -80°C.

GFP-based antiviral assay:

HFF were cultivated in 12-well plates to 90% confluency and used for infection with AD 169- GFP virus at a tissue culture infective dose of 0.5 (GFP-TCID50 0.5, referring to an MOI of 0.002 as determined by plaque assay titration). Virus inoculation was performed as described above. Then infected cell layers were incubated with 2.5 ml of MEM containing 5% (vol/vol) fetal calf serum with or without the respective test compound. Infected cells were incubated at 37°C under a 5% CO: atmosphere for 7 days. For lysis, 200 ml of lysis buffer (25 mM Tris [pH 7.8], 2 mM dithiothreitol [DTT], 2 mM trans- 1,2-di minocyclohexane-N,N,N9,N9- tetraacetic acid, 1% Triton X-100, 10% glycerol) was added to each well and incubated for 10 min at 37°C, followed by a 30-miii incubation at room temperature on a shaker. Lysates were eentriftiged for 5 min at 15,000 rpm in an Eppendorf centrifuge to remove cell debris. One hundred microliters of the supernatants was transferred to an opaque 96-well plate for automated measuring of GFP signals in a Victor 1420 Multilabel Counter (Wallac). The efficacy of the test compounds against virus was determined by comparing the compound- treated samples with the untreated infection control. Cytotoxicity assay:

HFF were cultivated in 48-well plates until contluency was reached. Antiviral compounds were added and cells were incubated at 37°C for 7 days, before a measurement of the lactate dehydrogenase (LDH) activity in the residual cell layer was performed by use of the CytoTox 96 Non-Radioactive Cytotoxicity Assay (Promega). For this, culture media were removed, and cells were rinsed with PBS and lysed in a concentration of the kit lysis buffer (100 ml per well). After incubation for 45 min at 37°C, the cell debris was removed by centrifugation and 10 ml of each lysate was diluted in a total of 50 ml of PBS for the determination of LDH activity. Fifty microliters of substrate mix was added to each well and incubated for 30 min at room temperature in the dark. Thereafter, 50 ml of stop buffer was added, and the color reaction was quantitated by use of an enzyme-linked immunosorbent assay (ELISA) reader (optical density [OD] at 490 nm).

11SV virus neutralization assay:

Neutralizing activities of the antiviral compound were determined by endpoint dilution assay as described previously (Krawczyk A. et al., J Virol. 201 1 ;85(4): 1793-803). Briefly, one day before infection. Vcro cells (2 x 10 4 per well) were seeded into a culture plate in Dulbecco's modified Eagle's medium (DMEM) supplemented with 10% heat-inactivated FBS, 100 U/rnl penicillin and 100 ^πιΐ streptomycin. Next day, serial dilutions of Aciclovir (Ratiopharm, Ulm, Germany) or compound 5 (3-400μΜ) in Dulbecco ' s modified Eagle's medium (DMEM) supplemented with 2% heat-inactivated FBS, 100 U/nil penicillin and 100 g/ml streptomycin were incubated with 100 TCID 50 of HSV-1 F, HSV-2 G or an Aciclovir- resistant clinical isolate for 2 days at 37°C on Vero cell monolayers. After two days, cell cultures were screened for plaque formation. The drug concentration required for reducing virus-induced cytopathic effect (CPE) by 100% was determined as the complete

neutralization titer.

For control purposes, virus without Aciclovir/compound 5 or Aciclovir/compound 5 alone, respectively, were used to induce maximal CPE and no CPE, respectively. Virus

neutralization assays were repeated at least twice with similar results.

The following HSV-strains were used: HSV-1 F: Herpes simplex virus type 1 , strain F: Aciclovir-sensitive wild-type lab strain. HSV-1 RIO: Herpes simplex virus type 1, clinical isolate: shows resistance to Aciclovir,

Foscarnet and Cidofovir.

HSV-2 G: Herpes simplex virus type 2, strain G: Aciclovir-sensitive wilde-type lab strain. HSV-2 R6: Herpes simplex virus type 2 clinical isolate: Aciclovir-resistant.

The results are shown in the following tables, wherein an X marks plaque format ion and thus cell lysis by viral infection, whereas an empty space indicates absence of cell lysis and thus virus neutralization :

Table l a: HSV- 1 F vs. Aciclovir

Table 3b: HSV-2 G vs. Cpd. 5 Table 4a: HSV-2 R6 vs. Aciclovir

Table 4b: HSV-2 R6 vs. Cpd. 5

It is shown that, in addition to Aciclovir-sensitive strains, compound 5 is able to neutralize Aciclovir-resistant HSV-1 and HSV-2 strains.
