(Formula Removed)
in which A and B have the meanings indicated below, and to processes and intermediates for the preparation of, compositions containing and the uses of such derivatives.
f$2 adrenergic agonists and cholinergic muscarinic antagonists are well-established therapeutic agents for the treatment of obstructive respiratory diseases such as COPD and Asthma. Currently used inhaled ß2 agonists include both short acting agents such as salbutamol (q.i.d.), and terbutaline (t.i.d) and longer acting agents such as salmeterol, and formoterol (b.i.d.) and produce bronchodilation via stimulation of adrenergic receptors on airway smooth muscle. Inhaled Muscarinic antagonists in clinical use include the short acting ipratropium bromide (q.i.d.), oxitropium bromide (q.i.d) and the long acting tiotropium (q.d.). Muscarinic antagonists produce bronchodilation by inhibiting the cholinergic tone of airways primarily by antagonising the action of acetylcholine on muscarinic receptors present on airway smooth muscle. A number of published studies have demonstrated that the combined administration of inhaled ß2 agonists with inhaled muscarinic antagonists (whether short or long acting) to patients with obstructive lung disease results in superior improvements in lung function, symptoms and quality of life measures compared to patients receiving either single class of agent alone. Studies to date have been restricted to combination studies with single pharmacology agents, however combination of both pharmacologies within a single molecule would be desirable as this could yleld increased bronchodilertor efficacy with similar therapeutic index to the single agents or similar efficacy with superior therapeutic index. In addition, combining both pharmacologies in a single molecule would allow the potential for combination with anti-inflammatory agents thus giving a triple therapy from a single inhaler.

For a review on suitable salts, see "Handbook of Pharmaceutical Salts: Properties, Selection, and Use" by Stahi and Wermuth (Wiley-VCH, Weinheim, Germany, 2002).
Pharmaceutical^ acceptable salts of compounds of formula (1) and quaternary ammonium salt
thereof may be prepared by one or more of three methods:
(i) by reacting the compound of formula (1) with the desired acid or base;
(ii) by removing an acid- or base-labile protecting group from a suitable precursor of the
compound of formula (1) or by ring-opening a suitable cyclic precursor, for example, a
lactone or lactam, using the desired acid or base; or (iii) by converting one salt of the compound of formula (1) to another by reaction with an
appropriate acid or base or by means of a suitable ion exchange column.
All three reactions are typically carried out in solution. The resulting salt may precipitate out and be collected by filtration or may be recovered by evaporation of the solyent. The degree of ionisation in the resulting salt may vary from completely ionised to almost non-ionised.
The compounds of the invention may exist in both unsolyated and solyated forms. The term 'solyate' is used herein to describe a molecular complex comprising the compound of the invention and a stoichiometric amount of one or more pharmaceutically acceptable solyent molecules, for example, ethanol. The term 'hydrate' is employed when said solyent is water.
Included within the scope of the invention are complexes such as clathrates, drug-host inclusion complexes wherein, in contrast to the aforementioned solyates, the drug and host are present in stoichiometric or non-stoichiometric amounts. Also included are complexes of the drug containing two or more organic and/or inorganic components which may be in stoichiometric or non-stoichiometric amounts. The resulting complexes may be ionised, partially ionised, or non-ionised. For a review of such complexes, see J Pharm Sci, 64 (8), 1269-1288 by Haleblian (August 1975).
Hereinafter all references to compounds of formula (1) include references to salts, solyates and complexes thereof and to solyates and complexes of salts thereof.
The compounds of the invention include compounds of formula (1) as hereinbefore defined, including all polymorphs and crystal habits thereof, prodrugs and isomers thereof (including optical, geometric and tautomeric isomers) as hereinafter defined and isotopically-labeled compounds of formula (1).
As indicated, so-called 'pro-drugs' of the compounds of formula (1) are also within the scope of the invention. Thus certain derivatives of compounds of formula (1) which may have little or no pharmacological activity themselyes can, when administered into or onto the body, be converted into compounds of formula (1) having the desired activity, for example, by hydrolylic cleavage. Such derivatives are referred to as 'prodrugs'. Further information on the use of prodrugs may be found in 'Pro-drugs as Novel Delivery Systems, Vol. 14, ACS Symposium Series (T. Higuchi and W. Stella) and 'Bioreversible Carriers in Drug Design', Pergamon Press, 1987 (ed. E. B Roche, American Pharmaceutical Association).
Prodrugs in accordance with the invention can, for example, be produced by replacing appropriate functionalities present in the compounds of formula (1) with certain moieties known to those skilled in the art as 'pro-moieties' as described, for example, in "Design of Prodrugs" by H. Bundgaard (Elsevier, 1985).
Some examples of prodrugs in accordance with the invention include:
(i) where the compound of formula (1) contains a methyl group, an hydroxymethyl
derivative thereof (-CH3 → -CH2OH):
(ii) where the compound of formula (1) contains an alkoxy group, an hydroxy derivative
thereof (-OR →-OH); (iii) where the compound of formula (1) contains a tertiary amino group, a secondary amino
derivative thereof (-NR1R2 → -NHR1 or -NHR2); (iv) where the compound of formula (1) contains a secondary amino group, a primary
derivative thereof (-NHR1 -»-NH2); (v) where the compound of formula (1) contains a phenyl moiety, a phenol derivative
thereof (-Ph -»-PhOH); and (vi) where the compound of formula (1) contains an amide group, a carboxylic acid
derivative thereof (-CONH2 → COOH).
Further examples of replacement groups in accordance with the foregoing examples and examples of other prodrug types may be found in the aforementioned references.
Moreover, certain compounds of formula (1) may themselyes act as prodrugs of other compounds of formula (1).
Also included within the scope of the invention are metabolites of compounds of formula (1), that is, compounds formed in wo upon administration of the drug. Some examples of metabolites in accordance with the invention include
(i) where the compound of formula (1) contains a secondary amino group, a primary derivative thereof (-NHR1 →-NH2), and
(ii) where the compound of formula (1) contains a phenyl moiety, a phenol derivative thereof (-Ph → -PhOH).
Included within the scope of the present invention are all stereoisomers, geometric isomers and tautomeric forms of the compounds of formula (1), including compounds exhibiting more than one type of isomerism, and mixtures of one or more thereof. Also included are acid addition or base salts wherein the counterion is optically active, for example, d-lactate or /-lysine, or racemic, for example, dl-tartrate or dl-arginine.
Cis/trans isomers may be separated by conventional techniques well known to those skilled in the art, for example, chromatography and fractional crystallisation.
Conventional techniques for the preparation/isolation of individual enantiomers include chiral synthesis from a suitable optically pure precursor or resolution of the racemate (or the racemate of a salt or derivative) using, for example, chiral high pressure liquid chromatography (HPLC).
Alternatively, the racemate (or a racemic precursor) may be reacted with a suitable optically active compound, for example, an alcohol, or, in the case where the compound of formula (1) contains an acidic or basic moiety, an acid or base such as tartaric acid or 1-phenylethylamine. The resulting diastereomeric mixture may be separated by chromatography and/or fractional crystallization and one or both of the diastereoisomers converted to the corresponding pure enantiomer(s) by means well known to a skilled person.
Chiral compounds of the invention (and chiral precursors thereof) may be obtained in enantiomerically-enriched form using chromatography, typically HPLC, on an asymmetric resin with a mobile phase consisting of a hydrocarbon, typically heptane or hexane, containing from 0 to 50% by volume of isopropanol, typically from 2% to 20%, and from 0 to 5% by volume of an alkylamine, typically 0.1% diethylamine. Concentration of the eluate affords the enriched mixture.
Stereoisomeric conglomerates may be separated by conventional techniques known to those skilled in the art - see, for example, "Stereochemistry of Organic Compounds" by E. L Eliel (Wiley, New York, 1994).
The present invention includes all pharmaceutically acceptable isotopically-labelled compounds of formula (1) wherein one or more atoms are replaced by atoms having the same atomic number, but an atomic mass or mass number different from the atomic mass or mass number which predominates in nature.
Examples of isotopes suitable for inclusion in the compounds of the invention include isotopes of hydrogen, such as 2H and 3H, carbon, such as 11C, 13C and 14C, chlorine, such as 38Cl, fluorine, such as 1flF, iodine, such as 123l and 12SI, nitrogen, such as 13N and 15N, oxygen, such as 15O, 170 and 180, phosphorus, such as 32P, and sulphur, such as 36S.
Certain isotopically-labelled compounds of formula (1), for example those incorporating a radioactive isotope, are useful in drug and/or substrate tissue distribution studies. The radioactive isotopes tritium, i.e. 3H, and carbon-14, i.e. 14C, are particularly useful for this purpose in view of their ease of incorporation and ready means of detection.
Substitution with heavier isotopes such as deuterium, i.e. 2H, may afford certain therapeutic advantages resulting from greater metabolic stability, for example, increased in vivo half-life or reduced dosage requirements, and hence may be preferred in some circumstances.
Substitution with positron emitting isotopes, such as 11C, 18F, 150 and 13N, can be useful in Positron Emission Topography (PET) studies for examining substrate receptor occupancy.
Isotopically-labeled compounds of formula (1). can generally be prepared by conventional techniques known to those skilled in the art or by processes analogous to those described in the accompanylng Examples and Preparations using an appropriate isotopically-labeled reagents in place of the non-labeled reagent previously employed.
Pharmaceutically acceptable solyates in accordance with the invention include those wherein the solyent of crystallization may be isotopically substituted, e.g. D2O, d6-acetone, d6-DMSO.
The compounds of formula (1), their pharmaceutically acceptable salts and/or derived forms, are valuable pharmaceutically active compounds, which are suitable for the therapy and prophylaxis of numerous disorders in which agonism of the ß2 receptor and antagonism of the muscarinic receptor may induce benefit, in particular the allergic and non-allergic airways diseases.
Compounds of the invention intended for pharmaceutical use may be administered as crystalline or amorphous products. They may be obtained, for example, as solid plugs, powders, or films by methods such as precipitation, crystallization, freeze drylng, spray drylng, or evaporative drylng. Microwave or radio frequency drylng may be used for this purpose.
They may be administered alone or in combination with one or more other compounds of the invention or in combination with one or more other drugs (or as any combination thereof). Generally, they will be administered as a formulation in association with one or more pharmaceutically acceptable excipients. The term "excipient" is used herein to describe any ingredient other than the compound(s) of the invention. The choice of excipient will to a large extent depend on factors such as the particular mode of administration, the effect of the excipient on solubility and stability, and the nature of the dosage form.
Pharmaceutical compositions suitable for the delivery of compounds of the present invention and methods for their preparation will be readily apparent to those skilled in the art. Such compositions and methods for their preparation may be found, for example, in "Remington's Pharmaceutical Sciences', 19th Edition (Mack Publishing Company, 1995).

Parenteral formulations are typically aqueous solutions which may contain excipients such as salts, carbohydrates and buffering agents (preferably to a pH of from 3 to 9), but, for some applications, they may be more suitably formulated as a sterile non-aqueous solution or as a dried form to be used in conjunction with a suitable vehicle such as sterile, pyrogen-free water.
The preparation of parenteral formulations under sterile conditions, for example, by lyophilisation, may readily be accomplished using standard pharmaceutical techniques well known to those skilled in the art.
The solubility of compounds of formula (1) used in the preparation of parenteral solutions may be increased by the use of appropriate formulation techniques, such as the incorporation of solubility-enhancing agents.
Formulations for parenteral administration may be formulated to be immediate and/or modified release. Modified release formulations include, delayed-, sustained-, pulsed-, controlled-, targeted and programmed release. Thus compounds of the invention may be formulated as a solid, semi-solid, or thixotropic liquid for administration as an implanted depot providing modified release of the active compound. Examples of such formulations include drug-coated stents and poly(dH actic-coglycolic)acid (PGLA) microspheres.
The compounds of the invention may also be administered topically to the skin or mucosa, that is, dermally or transdermally. Typical formulations for this purpose include gels, hydrogels, lotions, solutions, creams, ointments, dusting powders, dressings, foams, films, skin patches, wafers, implants, sponges, fibres, bandages and microemulsions. Liposomes may also be used. Typical carriers include alcohol, water, mineral oil, liquid petrolatum, white petrolatum, glycerin, polyethylene glycol and propylene glycol. Penetration enhancers may be incorporated - see, for example, J Pharm Sci, 88 (10), 955-958 by Finnin and Morgan (October 1999).
Other means of topical administration include delivery by electroporation, iontophoresis, phonophoresis, sonophoresis and microneedle or needle-free (e.g. Powderject™, Bioject™, etc.) injection.
Formulations for topical administration may be formulated to be immediate and/or modified release. Modified release formulations include delayed-, sustained-, pulsed-, controlled-, targeted and programmed release.
The compounds of the invention can also be administered intranasally or by inhalation, typically in the form of a dry powder (either alone, as a mixture, for example, in a dry blend with lactose,
or as a mixed component particle, for example, mixed with phospholipids, such as phosphatidylcholine) from a dry powder inhaler or as an aerosol spray from a pressurised container, pump, spray, atomiser (preferably an atomiser using electrohydrodynamics to produce a fine mist), or nebuliser, with or without the use of a suitable propellant, such as 1,1,1,2-tetrafluoroethane or 1,1,1,2,3,3,3-heptafluoropropane. For intranasal use, the powder may comprise a bioadhesive agent, for example, chitosan or cyclodextrin.
The pressurised container, pump, spray, atomizer, or nebuliser contains a solution or suspension of the compound(s) of the invention comprising, for example, ethanol, aqueous ethanol, or a suitable alternative agent for dispersing, solubilising, or extending release of the active, a propellant(s) as solyent and an optional surfactant, such as sorbitan trioleate, oleic acid, or an oligolactic acid.
Prior to use in a dry powder or suspension formulation, the drug product is micronised to a size suitable for delivery by inhalation (typically less than 5 microns). This may be achieved by any appropriate comminuting method, such as spiral jet milling, fluid bed jet milling, supercritical fluid processing to form nanoparticles, high pressure homogenisation, or spray drylng.
Capsules (made, for example, from gelatin or hydroxypropylmethylcellulose), blisters and cartridges for use in an inhaler or insufflator may be formulated to contain a powder mix of the compound of the invention, a suitable powder base such as lactose or starch and a performance modifier such as Weucine, mannitol, or magnesium stearate. The lactose may be anhydrous or in the form of the monohydrate, preferably the latter. Other suitable excipients include dextran, glucose, maltose, sorbitol, xylitol, fructose, sucrose and trehalose.
A suitable solution formulation for use in an atomiser using electrohydrodynamics to produce a fine mist may contain from 1µg to 20mg of the compound of the invention per actuation and the actuation volume may vary from 1µl to 100ul. A typical formulation may comprise a compound of formula (1), propylene glycol, sterile water, ethanol and sodium chloride. Alternative solyents which may be used instead of propylene glycol include glycerol and polyethylene glycol.
Suitable flavours, such as menthol and levomenthol, or sweeteners, such as saccharin or saccharin sodium, may be added to those formulations of the invention intended for inhaled/intranasal administration.
Formulations for inhaied/intranasal administration may be formulated to be immediate and/or modified release using, for example, PGLA. Modified release formulations include delayed-, sustained-, pulsed-, controlled-, targeted and programmed release.
In the case of dry powder inhalers and aerosols, the dosage unit is determined by means of a valye which delivers a metered amount. Units in accordance with the invention are typically arranged to administer a metered dose or "puff" containing from 0.001 mg to 10mg of the compound of formula (1). The overall daily dose will typically be in the range 0.001 mg to 40mg which may be administered in a single dose or, more usually, as divided doses throughout the day.
The compounds of formula (1) are particularly suitable for an administration by inhalation.
The compounds of the invention may be administered rectally or vaginally, for example, in the form of a suppository, pessary, or enema. Cocoa butter is a traditional suppository base, but various alternatives may be used as appropriate.
Formulations for rectal/vaginal administration may be formulated to be immediate and/or modified release. Modified release formulations include delayed-, sustained-, pulsed-, controlled-, targeted and programmed release.
The compounds of the invention may also be administered directly to the eye or ear, typically in the form of drops of a micronised suspension or solution in isotonic, pH-adjusted, sterile saline. Other formulations suitable for ocular and aural administration include ointments, biodegradable {e.g. absorbable gel sponges, collagen) and non-biodegradable (e.g. silicone) implants, wafers, lenses and particulate or vesicular systems, such as niosomes or liposomes. A polymer such as crossed-linked poiyacrylic acid, polyvinylalcohol, hyaluronic acid, a cellulosic polymer, for example, hydroxypropylmethylcellulose, hydroxyethylcellulose, or methyl cellulose, or a heteropolysaccharide polymer, for example, gelan gum, may be incorporated together with a preservative, such as benzalkonium chloride. Such formulations may also be delivered by iontophoresis.
Formulations for ocular/aura) administration may be formulated to be immediate and/or modified release. Modified release formulations include delayed-, sustained-, pulsed-, controlled-, targeted, or programmed release.
The compounds of the invention may be combined with soluble macrornolecular entities, such as cyclodextrin and suitable derivatives thereof or polyethylene glycol-containing polymers, in order to improve their solubility, dissolution rate, taste-masking, bioavailability and/or stability for use in any of the aforementioned modes of administration.
Drug-cyclodextrin complexes, for example, are found to be generally useful for most dosage forms and administration routes. Both inclusion and non-inclusion complexes may be used. As
an alternative to direct complexation with the drug, the cyclodextrin may be used as an auxiliary additive, i.e. as a carrier, diluent, or solubiliser. Most commonly used for these purposes are alpha-, beta- and gamma-cyclodextrins, examples of which may be found in International Patent Applications Nos. WO 91/11172, WO 94/02518 and WO 98/55148.
Inasmuch as It may desirable to administer a combination of active compounds, for example, for the purpose of treating a particular disease or condition, it is within the scope of the present invention that two or more pharmaceutical compositions, at least one of which contains a compound in accordance with the invention, may conveniently be combined in the form of a kit suitable for coadministration of the compositions.
Thus the kit of the invention comprises two or more separate pharmaceutical_cornpositions, at least one of which contains a compound of formula (1) in accordance with the invention, and means for separately retaining said compositions, such as a container, divided bottle, or divided foil packet. An example of such a kit is the familiar blister pack used for the packaging of tablets, capsules and the like.
The kit of the invention is particularly suitable for administering different dosage forms, for example parenteral, for administering the separate compositions at different dosage intervals, or for titrating the separate compositions against one another. To assist compliance, the kit typically comprises directions for administration and may be provided with a so-called memory aid.
For administration to human patients, the total daily dose of the compounds of the invention is typically in the range 0.001 mg to 5000mg depending, of course, on the mode of administration. For example, an intravenous daily dose may only require from 0.001 mg to 40mg. The total daily dose may be administered in single or divided doses and may, at the physician's discretion, fall outside of the typical range given herein.
These dosages are based on an average human subject having a weight of about 65kg to 70kg. The physician will readily be able to determine doses for subjects whose weight falls outside this range, such as infants and the elderly.
For the avoidance of doubt, references herein to "treatment" include references to curative, palliative and prophylactic treatment.
