Description

SOLUBLE AZOLES IN WATER AS WIDE ANTIFUNGICOS OF SPECTRUM The present invention relates to water soluble azoles as broad spectrum antifungals, as well as to their preparation; it also refers to the compositions that contain them, and also to their use as a medicine. Systemic fungal infections in man are relatively rare in temperate countries and many of the fungi that can become pathogenic live normally in the body or are common in the environment. In recent decades there has been an increasing incidence of numerous systemic fungal infections with risk to life worldwide and these now represent a significant threat to many susceptible patients, especially those who are already hospitalized. Most of the increase can be attributed to the longer survival of immunocompromised patients and the chronic use of antimicrobial agents. In addition, the typical flora of numerous fungal infections is also changing and this represents an epidemiological challenge of increasing importance. Patients at increased risk include those with impaired immune functioning, either directly as a result of immunosuppression caused by cytotoxic drugs or by HIV infection, or that which occurs as a consequence of other debilitating diseases such as cancer, acute leukemia , aggressive surgical techniques or Iu | ^ prolonged exposure to antimicrobial agents. The most common fungal infections in man are candidosis, aspergillosis, histoplasmosis, coccidioidomycosis, paracoccidioidomycosis, blastomycosis and cryptococcosis. Antifungals such as ketoconazole, itraconazole and fluconazole are used for the treatment and prophylaxis of systemic fungal infections in immunocompromised patients. However, there is growing concern about fungal resistance to some of these agents, especially those with a relatively narrow spectrum, for example fluconazole. Worse yet, in the medical world it is a recognized fact that approximately 40% of people suffering from severe systemic fungal infections can barely, if they can, receive medication orally. This disability is due to the fact that these patients are in a coma or suffer from severe gastroparesis. Therefore, the use of insoluble or poorly soluble antifungals such as itraconazole, which are difficult to administer intravenously, is extremely difficult in this group of patients. In addition, the treatment of onychomycosis can be facilitated by potent water-soluble antifungals. For some time it has been desired to treat onychomycosis by the transungual route. The problem that arises then is to ensure that antifungal agents penetrate the nail and below it. Mertin and Lippold (J. Pharm. Pharmacol. (1997), 49, 30-34) stated that to trace drugs (drugs) for topical application to the nail plate, attention should be paid primarily to the water solubility of the compound. The maximum flow through the nail is beneficially influenced by the increase in the water solubility of the antifungal. Naturally, the efficacy in the treatment of onychomycosis by the transungual route also depends on the potency of the antifungal agent. Consequently, there is a need to have new antifungals, preferably broad spectrum antifungals, against which there is no resistance and which can be administered intravenously or transungueally. Preferably, the antifungal should be presented in a pharmaceutical composition suitable for oral administration. This allows the doctor to continue the treatment with the same drug once the patient has recovered from the state that justifies the intravenous or transungual administration of said drug. U.S. Patent No. 4,267,179 describes heterocyclic derivatives of (4-phenylpiperzin-1-yl-aryloxy-methyl-1,3-dioxolan-2-yl) -methyl-1 H-imidazoles and 1 -1, 2,4-triazoles useful as antifungal agents.
This patent covers itraconazole, which is available as a broad-spectrum antifungal agent throughout the world. WO 93/19061 describes the stereospecific isomers of itraconazole [2R- [2a, 4a, 4 (R *)] j, [2í- [2a, 4a, 4 (S *)] j, [2S- [2, 4 , 4 (S *)] j and [2S- [2a, 4a, 4 (*)] j, of which it is known that they have greater solubility in water than the respective diastereomeric mixtures thereof.
WO 95/19983, describes derivatives of [[4- [4- (4-phenyl-1-piperazinyl) phenoxy-methyl] -1, 3-dioxolan-2-yl] methyl] -1H-imidazoles and 1H-1 , 2,4-triazoles, which are structurally related to some of the compounds of the present invention, and which are described as water-soluble antimicrobial agents. WO 95/17407 describes tetrahydrofuran antifungals, as well as WO 96/38443 and WO 97/00255. These two last publications describe tetrahydrofuran antifungals, which are described as soluble and / or suspensible in an aqueous medium suitable for intravenous administration, which contain substitution groups easily convertible in vivo to hydroxy groups. Saksena et al., In Bioorganic & Medicinal Chemistry Letters (1995), 5 (2), 127-132, discloses some azole antifungals based on tetrahydrofuran such as (3R-c / s) -4- [4- [4- [4 - [[5- (2,4-difluorophenyl) tetrahydro-5- (1H-1, 2,4-triazol-1-ylmethyl) -3-furanyl] methoxy] phenyl] -1-piperazinyl] phenyl] -2- [2- (dimethylamino ) ethyl] -2,4-dihydro-3H-1, 2,4-triazol-3-one. Saksena et al. Stated that said azole, in comparison with SCH 51048, was extremely less active as an antifungal agent. Surprisingly, the compounds of the present invention are potent broad spectrum antifungals with good solubility in water.

The above-mentioned pharmaceutically acceptable addition salts should comprise the non-toxic therapeutically active acid addition salt forms which the compounds of the formula (I) can form. The latter can be conveniently obtained by treating the base form with appropriate acids such as inorganic acids, for example, hydrohalic acids, for example hydrochloric, hydrobromic and the like; sulfuric acid; nitric acid; phosphoric acid and the like; or organic acids, for example, acetic, propanoic, hydroxyacetic, 2-hydroxypropanoic, 2-oxopropanoic, oxalic, malonic, succinic, maleic, fumaric, malic, tartaric, 2-hydroxy-1, 2,3-propanetricarboxylic, methanesulfonic, ethanesulfonic, benzenesulfonic, 4- _____________ _! _ methylbenzenesulfonic, cyclohexanesulfamic, 2-hydroxybenzoic, 4-amino-2-hydroxybenzoic acid and similar acids. Conversely, the salt form can be converted by treatment with an alkali to the free base form. The compounds of the formula (I) containing acidic protons can be converted to their therapeutically active non-toxic metal or amine addition salt forms by treatment with the appropriate organic and inorganic bases. Suitable basic salt forms include, for example, the ammonium salts, alkali metal and alkaline earth metal salts, for example the lithium, sodium, potassium, magnesium, calcium salts and the like, salts such as organic bases, for example benzathine, ? / - methyl-D-glucamine, 2-amino-2 (hydroxymethyl) -1, 3-propanediol, hydrabamine salts and salts with amino acids such as, for example, arginine, lysine and the like. Conversely, the salt form can be converted by acid treatment to the free acid form. The term addition salt also includes the hydrates and solvent addition forms that the compounds of the formula (I) can form. Examples of such forms are, for example, hydrates, alcoholates and others. The term "stereochemically isomeric forms" used above defines all possible stereoisomeric forms in which the compounds of the formula (I) exist; therefore, all enantiomers, enantiomeric mixtures and diastereomeric mixtures are also included. Unless otherwise mentioned or indicated, the Chemical designation of the compounds denotes the mixture of all possible stereoisomeric forms, said mixtures contain all the diastereomers and enantiomers of the basic molecular structure. The same applies to the intermediates described herein, used to prepare the final products of the formula (I). The pure stereoisomeric forms of the compounds and intermediates mentioned herein are defined as isomers substantially free of other enantiomeric or diastereomeric forms of the same molecular basic structure of said compounds or intermediates. In particular, the term "stereoisomerically pure", which is equivalent to "chirally pure" refers to compounds or intermediates having a stereoisomeric excess of at least 80% (ie, a minimum of 90% of an isomer and a maximum from 10% of the other possible isomers) to a stereoisomeric excess of 100% (ie, 100% of an isomer and nothing of the other), more specifically, compounds or intermediates having a stereoisomeric excess of 90% to 100%, even more in particular those having a stereoisomeric excess of 94% up to 100% and very particularly those having a stereoisomeric excess of 97% up to 100%. The terms "enantiomerically pure" and "diastereomerically pure" should be interpreted in a similar manner, only with respect to the enantiomeric excess, respectively the diastereomeric excess of the mixture in question. The terms cis and trans are used in the present in accordance with the Chemical Abstracts nomenclature and refer to the position of the substituents on a portion of the ring, more specifically on the dioxolane ring of the compounds of the formula (I). For example, when the cis or trans configuration of the dioxolane ring is established in a radical of the formula (Dt), the substituent with the highest priority is considered to be the carbon atom in the 2-position of the dioxolane ring and the substituent with the highest priority over the carbon atom in the 4 position of the dioxolane ring (the priority of a substituent is determined according to the rules of the Cahn-Ingold-Prelog sequence). When said two substituents with the highest priority are on the same side of the ring, then the configuration is designated cis; otherwise, the configuration is considered trans. All compounds of the formula (I) contain at least 2 asymmetric centers which may have the R- or S- configuration. In the present, the stereochemical descriptors that indicate the stereochemical configuration of each of the 2 or more asymmetric centers are also in accordance with the Chemical Abstracts nomenclature. For example, the absolute configuration of the asymmetric carbon atoms of compound 86, ie, [2S- [2a, 4a [(R *, S *) (S *)]]] - 4- [4- [4- [4 - [[2- (2,4-difluorophenyl) -2- (1H-1, 2,4-triazol-1-yl-methyl) -1, 3-dioxolan-4-yl] methoxy] phenyl] - 1-piperazinyl] phenyl] -2,4-dihydro-2- [2 - [(1-phenylethyl) amino] -1-methylpropyl] -3H-1, 2,4-triazol-3-one, it is as illustrated below. The dioxolane ring in this compound has the cis configuration.
The ring numbering in the dioxolane ring is presented according to the Chemical Abstracts nomenclature for the Di and D radicals that appear immediately below.
The absolute stereochemical configuration of some compounds of the formula (I) and of the intermediates used in their preparation has not been determined experimentally. In those cases, the stereoisomeric form isolated in the first place receives the designation "A", the second "B" and if there are more stereogenic forms, the third is "C", the fourth "D" and so on, without further reference to the actual stereochemical configuration. However, the stereogenic forms called "A", "B", "C", "D" and so on can be characterized unequivocally. By example, if "A" and "B" have an enantiomeric relationship, can be unequivocally characterized by their optical rotation. One skilled in the art can determine the absolute configuration of such compounds using methods known in the art such as, for example, X-ray diffraction. If "A" and "B" are stereoisomeric mixtures, they can be further separated, so which the respective first isolated fractions are designated "A1" and "B1" and the second "A2" and "B2", without further reference to the actual stereochemical configuration. The N-oxide forms of the present compounds should encompass the compounds of the formula (I) in which one or several nitrogen atoms are oxidized to the so-called N-oxide. Each time it is used hereafter, the term "compound of formula (I)" must also include its N-oxide forms, its pharmaceutically acceptable addition salts and its stereochemically isomeric forms.

The compounds of the present invention in which Rβ and R7 are not hydrogen, said Rβ and R7 being represented by R6 and R7 and said compounds represented by the formula (I '), can be prepared by reacting an intermediate of the formula ( II) in which W1 is a suitable leaving group such as, for example, a halogen, for example iodine, an arylsulphonyloxy or alkanesulfonyloxy group, for example p-toluenesulfonyloxy, naphthylsulfonyloxy or methanesulfonyloxy, with an intermediate of the formula (III) in a reaction-inert solvent such as, for example, N, N-dimethylformamide,? /,? / - dimethylacetamide, 1-methyl-2-pyrrolidinone, 1,3-dimethyl-2-imidazolidinone, sulfolane or the like, and in the presence of a suitable base such as, for example, sodium hydroxide or sodium hydride.
In this and the following preparations, the reaction products can be isolated from the reaction medium and, if necessary, further purified according to the methodologies generally known in the art such as, for example, extraction, crystallization, trituration and chromatography. In particular, stereoisomers can be isolatedchromatographically used a chiral stationary phase such as, for example, Chiralpak AD (3,5-dimethylphenylcarbamate amylose) or Chiralpak AS, both purchased from Daicel Chemical Industries, Ltd., in Japan. The compounds of the formula (I ') can also be prepared by N-alkylating an intermediate of the formula (IV) with an intermediate of the formula (V) in which W2 is a suitable leaving group such as, for example, a halogen and in which the reactive amino groups in L such as primary and secondary amines, if present, are protected with a protecting group P such as, for example, a C 1-4 alkyloxycarbonyl group, in a solvent inert to the reaction such as, for example, dimethyl sulfoxide, in the presence of a base such as, for example, potassium hydroxide. If L were protected, deprotection techniques known in the art could be employed to reach the compounds of the formula (I ') after the N-alkylation reaction.
+ L-W2 (.) (IV) (V) The compounds of the formula (I ') in which L is a radical of the formula (a), said compounds are represented by the formula (l'-a), can be prepared by the reaction of an intermediate of the formula (VI) in which W3 is a suitable leaving group such as, for example, a halogen, an arylsulfonyloxy group or an alkanesulfonyloxy group, for example p- toluenesulfonyloxy, naphthylisulfonyloxy or methanesulfonyloxy, with an intermediate of the formula (VII) optionally in the presence of a suitable base such as, for example, sodium or potassium carbonate, triethylamine or the like, and optionally in a reaction-inert solvent such as, for example, N, N-dimethylformamide? /,? / - dimethylacetamide, 1-methyl-2-pyrrolidinone, 1,3-dimethyl-2-imidazolidinone, sulfolane or the like. In case R1 and R2 form, together with the nitrogen atom to which they are attached, an azido radical, it can be used Na 3 as an intermediary of the formula (VII). (fa) The compounds of the formula (I) in which at least one of R6 or R7 is hydrogen, said R6 and R7 being represented by R6 and R7 and said compounds being represented by the formula (I "), can be Prepare following the reaction procedure illustrated in scheme 1.

The intermediates of the formula (VI 11-b) thus obtained can be deprotected according to deprotection techniques known in the art, thereby obtaining an amine derivative of the formula (Vlll-c). In case NP2 is a nitro group, reduction techniques known in the art can be used to obtain amines of the formula (Vlll-c). The amine derivatives of the formula (Vlll-c) can then be reacted with phenyl chloroformate or a functional derivative thereof. To obtain the compounds of the formula (I ") in which R6" is alkyl Ci. 4, the amine derivatives of the formula (Vlll-c) can first be reacted with where W4 is a suitable leaving group such as, for example, a halogen, and then reacting them with phenyl chloroformate. The intermediates of the formula (Vlll-e) thus obtained can be reacted with an intermediate of the formula (IX) in which the reactive amino groups in L such as primary and secondary amines, if present, are protected with a protecting group P such as, for example, a C 1-4 alkyloxycarbonyl group. Conveniently, the amino reactive group can be deprotected using deprotection techniques known in the art to reach the desired compound of the formula (I ".) The compounds of the formula (I) can also be converted to each other following transformations known in the art. For example, compounds of the formula (I ') in which L is a radical of the formula (b), compounds that are represented by the formula (l'-b), can be prepared using known acylation methods in the technique, for example those described in "Principies of Peptide Synthesis", M. Bodanszky, Springer-Verlag Berlin Heidelberg, 1984.
A special acylation process involves the acylation of a compound of the formula (1-a) in which R 1 is hydrogen, which compound is represented by the formula (1-a-1), with an intermediate of the formula ( Xb) in which W5 is a suitable leaving group such as, for example, a halogen or a hydroxy group, in the presence of a suitable base such as, for example, sodium bicarbonate or? /,? / - dimethylaminopyridine or a functional derivative thereof, and in a solvent inert to the reaction such as, for example, dichloromethane, dichloroethane, tetrahydrofuran or the like.

If W5 is hydroxy, it may be convenient to activate the carboxylic acid of the formula (Xb) by the addition of a diimide such as, for example,? /,? / '- dicyclohexylcarbodiimide, 1- (3-dimethylaminoporyl) -3-ethylcarbodiimide or a functional derivative thereof. On the other hand, the carboxylic acid of the formula (X-b) can be activated by adding carbonyldiimidazole or a functional derivative thereof. In case of using a chirally pure intermediate of the formula (X-b), quick couplings can be made without enantiomerization by the addition of hydroxybenzotriazole, benzotriazolyloxytris (d? methylamino) phosphonium hexafluorophosphate, tetrapyrrolidinophosphonium hexafluorophosphate, bromotripyrrolidinophosphonium hexafluorophosphate or a functional derivative thereof (D. Hudson, J. Org. Chem., 1988, 53, page 617/1999 Novabiochem catalog &peptide Synthesis Handbook). An acylation process analogous to that of the preparation of the compounds of the formula (l'-b) can be used for the preparation of the compounds of the formula (I ') in which L is a radical of the formula (c) , said compounds are represented by the formula (l'-c). In said analogous reaction procedure, the intermediate of the formula (Xb) is replaced by a carbonate of the formula alk? IC? 4-0-C (= 0) -0-R1 (Xc-1), a chloroformate of the formula CI-C (= 0) -0-R1 (Xc-2) or alkylCM-0-C (= 0) -0-C (= 0) -0-alkyl CM (Xc-3). An acylation process analogous to that of the preparation of the compounds of the formula (I-b) can be used for the preparation of the compounds of the formula (I ') in which L is a radical of the formula (d) , said compounds are represented by the formula (l'-d). In said analogous reaction process, the intermediate of the formula (Xb) is replaced by an isocyanate of the formula 0 = C = N-R1 (Xd-1), an isothiocyanate of the formula S = C = N-R1 (Xd) -2), a phenylcarbamate of the formula fera / -0-C (= 0) -NR1R2 (Xd-3), a phenylthiocarbamate of the formula phenyl-0-C (= S) -NR R2 (Xd-4) or an intermediate of the formula alkyl ^ SC (= NR2) -NR1R2 (Xd-5).
Reductive N-alkylation of the compounds of the formula (l'-a-1) can also be carried out with an aldehyde or ketone of the formula R1aC (= 0) R1b (XI) in which R1a and R1b are defined as Thus, the radical -CHR1aR1b is encompassed by the definition of R1, thus forming the compounds of the formula (l'-a-2). This reductive N-alkylation can be carried out in a solvent inert to the reaction such as, example, toluene, methanol, tetrahydrofuran or a mixture thereof, and in the presence of a reducing agent such as, for example, a borohydride, for example, sodium borohydride, zinc borohydride, lithium borohydride, sodium cyanoborohydride or borohydride of tpacetoxy In case of using borohydride as a reducing agent, it may be advantageous to use a catalyst such as, for example, titanium (IV) isopropoxide according to that described in J Org Chem 1990, 55, 2552-2554 It may also be convenient to use hydrogen as a reducing agent in combination with a suitable catalyst such as, for example, palladium on carbon or platinum on carbon The formation of a Schiff base in the first step of the reductive N-alkylation can be increased by the addition of a suitable reagent to the reaction mixture, such as, for example, aluminum urea-butoxide, calcium oxide, calcium hydride or a titanium (IV) alkoxide, for example titanium (IV) isopropoxide or titanium (IV) n-butoxide. A poison can also be added catalyst, for example, thiophene, butanediol or quinoline-sulfur to the reaction mixture to prevent further harmful hydrogenation of certain functional groups in the reactants and the reaction products. Agitation and, optionally, elevated temperatures and / or pressures may increase the rate of reaction. or AA • ""? f? TO.
The compounds of the formula (I ') in which L is a radical of the formula (a) and R1 is a substituent -CH2-CH (OH) in which the substituent belongs to the group of substituents composed of C1.6 alkyl , in the definition of R1, compounds that are represented by the formula (l'-a-3), can be prepared by reacting an intermediate of the formula (l'-a-1) with an epoxide of the formula (XII) in a solvent inert to the reaction such as, for example, 2-propanol. listener or,,,. II 2 OH 'l - N N -? - N N- Alk- N-CH2-? H \ - * - '^ ß- ¿- substituent (r-a-3) The compounds of the formula (I) which contain an alkyloxycarbonylamino C 1 - moiety can be converted to the compounds of the formula (I) which contain the corresponding amino moiety using techniques _j _? ________ i_l ___? __ i known in the art such as, for example, the reaction in dichloromethane and in the presence of trifluoroacetic acid. The compounds of the formula (I ') which contain a primary amine may be monomethylated by first protecting the primary amine with a suitable protecting group such as, for example, an arylalkyl group, for example benzyl, and then methylating the secondary amine employing techniques of methylation known in the art such as, for example, the reaction with paraformaldehyde. The tertiary amine thus obtained can be deprotected using deprotection techniques known in the art such as, for example, the reaction with hydrogen in tetrahydrofuran or methanol and in the presence of a catalyst such as, for example, palladium on carbon, to thereby obtain the secondary methylated amine. The compounds of the formula (I) can also be converted to the corresponding forms of? -oxides following art-known procedures for converting a trivalent nitrogen to its N-oxide form. Said? / -oxidation reaction can be carried out generally by reacting the starting material of the formula (I) with an appropriate organic or inorganic peroxide. Suitable inorganic peroxides include, for example, hydrogen peroxide, alkali metal or alkaline earth metal peroxides, for example sodium peroxide, potassium peroxide; suitable organic peroxides may include peroxyacids such as, for example, benzenecarboperoxoic acid or benzenecarboperoxoic acid substituted with halogen, for example 3-chlorobenzenecarboperoxoic acid, peroxoalkanoic acids, for example, peroxoacetic acid, alkylhydroperoxides, for example ferro-butyl hydroperoxide. Suitable solvents are, for example, water, lower alkanes, for example ethanol and the like, hydrocarbons, for example toluene, ketones, for example 2-butanone, halogenated hydrocarbons, for example dichloromethane and mixtures of the mentioned solvents. Some of the intermediates and starting materials used in the said processes can be obtained commercially, or they can be synthesized according to procedures described in other documents, for example US 4,791,111, US 4,931,444 and US 4,267,179. Further, in the present document, some methods of preparing the intermediates according to the present invention are described. For example, the intermediates of the formula (III) in which L is a radical of the formula (a), intermediates which are represented by the formula (III-a), can be prepared by reducing amination with a carbonyl-containing intermediate of the formula (XIII) in which Alk = 0 is equal to Alk substituted with an oxo group, with an intermediate of the formula (VII) following the same reaction procedures described for the reductive? -alkylation of the compounds of the formula (l'-a-1) with the intermediaries of the formula (XI).
(XIII) (VII) (III-a) The reaction procedure described can be carried out with chirally pure starting materials, employing stereoselective reaction procedures, to thereby obtain chirally pure intermediates of the formula (III-a). For example, a stereoselective reductive amination of a chirally pure form of an intermediate of the formula (XIII) with a chirally pure form of the formula (VII) can be a reaction using hydrogen on palladium on carbon as a reducing agent in the presence of a thiophene solution and titanium (IV) isopropoxide. The resulting stereoisomeric forms can be separated using chromatographic or other techniques known in the art. It may also be convenient to carry out the reaction described in the alkylphenoxy derivatives of the intermediates of the formula (XIII). The intermediates of the formula (III-a) in which R1 is an arylalkyl group Ci-β can be reduced using reduction techniques known in the art such as, for example, a reduction with hydrogen in the presence of palladium on activated carbon, to get like this intermediates of the formula (III-a) in which R is hydrogen, intermediates that are represented by the formula (III-a-1).
Said intermediates of the formula (III-1) can be converted to the intermediates of the formula (III) in which L is a radical of the formula (b), (c) or (d), which are represented by the formula (III-B), (III-C) and (III-D) respectively, using acylation methods known in the art, for example those described in "Principies of Peptide Synthesis", M. Bodanszky, Springer-Verlag Berlin Heidelberg, 1984 and 1999 Novabiochem Catalog & Peptide Synthesis Handbook. In addition, the amides of the formula (III-b) can be hydrolyzed using a suitable acid such as, for example, hydrochloric acid, to thereby obtain the intermediates of the formula (III-a-1). The stereoisomerically pure forms of the compounds and intermediates of the present invention can be obtained by the application of procedures known in the art. The diastereomers can be separated by physical separation methods such as selective crystallization and chromatographic techniques, for example liquid chromatography using chiral stationary phases. The enantiomers can be separated one of another by selective crystallization of its diastereomeric salts with optically active acids. On the other hand, the enantiomers can be separated by chromatographic techniques using chiral stationary phases. Said pure stereoisomeric forms can also be obtained from the corresponding pure stereoisomeric forms of the suitable starting materials, provided that the reaction occurs stereoselectively or stereospecifically. Preferably, if a specific stereoisomer is desired, said compound is synthesized by stereoselective or stereospecific methods of preparation. These methods will conveniently employ chirally pure starting materials. As is evident, the stereoisomeric forms of the compounds of the formula (I) should be considered included within the scope of the present invention. The chirally pure forms of the compounds of the formula (I) form a preferred group of compounds. It is for that reason that the chirally pure forms of the intermediates of the formulas (II), (III) and (VI), their forms of? Oxide and its addition salt forms are of particular utility in the preparation of the chirally pure compounds of the formula (I). The enantiomeric mixtures and the diastereomeric mixtures of the intermediates of the formulas (II), (III) and (VI), are also useful for the preparation of the compounds of the formula (I) with the corresponding configuration. Said chirally pure forms and also the enantiomeric mixtures and The diastereomers of the intermediates of the formula (III) are considered novel. A specific way of stereoselectively preparing the intermediates of the formula (III-a) in which R1 and R2 are hydrogen and Alk is -CH (CH3) -CH (CH3) - where both asymmetric carbon atoms have the S configuration -, and are represented by the formula (SS) (III-a-2), or the alkoxyphenyl analogs thereof, is the one illustrated in scheme 2a.
SCHEME 2a The reaction of an intermediate of the formula (XIV) with (4R-frans) -4,5-dimethyl-2,2-dioxide-1,2,2-dioxathiolane can be carried out in a suitable solvent, preferably a solvent polar aprotic such as, for example, dimethylacetamide or? /,? / - dimethylformamide and in the presence of a base such as, for example, potassium ferc-butanolate, potassium hydroxide or potassium hydride. Next, an acid such as sulfuric acid can be added to the reaction mixture, to thereby obtain an intermediate of the formula (SR) (XV) whereby the 2-hydroxy-1-methylpropyl portion has the erythro form. Then, the carbon atom carrying the alcohol function of said 2-hydroxy-1-methylpropyl portion is epimerized, preferably 100% inverted, to obtain the intermediary (SS) (XVII) whereby the 2-amino-1-methylpropyl portion has the threo form. Two roads are convenient. A first path includes the transformation of the alcohol function into a suitable leaving group O-LG, for example, by derivatizing the hydroxy group with an organic acid such as, for example, a sulfonic acid, for example p-toluenesulfonic acid or acid methanesulfonic acid, to thereby obtain an intermediate of the formula (SR) (XVI). The carbon atom carrying the leaving group in said intermediate (SR) (XVI) can then be epimerized, preferably 100% inverted, by a SN2-type reaction with a nucleophilic reagent such as, for example, NaN3, which can then be be reduced to the primary amine of the formula (SS) (XVII). On the other hand, the synthesis of Gabriel, its modification of Ing-Manske or another functional modification thereof can be used to prepare a primary amine of the formula (SS) (XVII). An alternative change to reverse the stereochemistry of the carbon atom that carries the alcohol function is the use of the Mitsunobu reaction. The alcohol function of an intermediate of the formula (SR) (XV) is active with diisopropyl azodicarboxylate or a functional derivative thereof such as diethylazodicarboxylate, in the presence of triphenylphosphine and in a polar aprotic solvent such as, for example, dimethylacetamide or dimethylformamide. The activated alcohol thus obtained is then reacted with an amide such as, for example, 2,2,2-trifluoroacetamide or a functional derivative thereof. Then the amide thus obtained, whereby the 2-hydroxy-1-methylpropyl portion has been transformed to the threo form can be hydrolyzed using hydrolysis techniques known in the art, to thereby obtain an intermediate of the formula (SS) (XVII). In order to obtain the intermediates of the formula (SR) (XVII), an additional investment step can be introduced as illustrated in scheme 2b.
SCHEME 2b The intermediaries of the formula (SR) (XV) are converted to an intermediate of the formula (SS) (XV) using two possible paths. A first path includes the transformation of the alcohol function into a suitable output group O-LG according to what has been described above, to obtain thus an intermediate of the formula (SR) (XVI). The carbon atom carrying the starting group in said intermediate (SR) (XVI), preferably 100% inverted, can then be epimerized by means of a SN2-type reaction with a suitable nucleophilic reagent such as, for example, an alcoholate, example a benzyloxy group; a hydroxy salt of an alkali metal, for example sodium hydroxide or potassium hydroxide; an acetate, for example sodium acetate. Said reaction is carried out in a suitable solvent, preferably a polar aprotic solvent such as, for example, dimethylacetamide, α / - methylpyrrolidone, dimethylimidazolidinone or sulfolane. In case of using an alcoholate or an acetate in the SN2 reaction; the intermediary thus obtained can be deprotected using deprotection techniques known in the art, to thereby obtain an alcohol intermediate of the formula (SS) (XV). Another path consists of Mitsunobu's reaction. The alcohol function of an intermediate of the formula (SR) (XV) is activated in the manner described above. The activated alcohol thus obtained is then reacted with a carboxylic acid such as, for example, 4-nitrobenzoic acid, acetic acid, monochloroacetic acid. The ester thus obtained can then be hydrolyzed using hydrolysis techniques known in the art, to thereby obtain an intermediate of the formula (SS) (XV). The intermediates of the formula (SS) (XV) can then be reacted to obtain intermediates of the formula (SR) (XVII) using the same reaction pathways described for the preparation of the intermediates (SS) (XVII) from (SR) (XV). Finally, the alkoxyphenyl portion of the intermediates of the formula (SS) (XVII) or (SR) (XVII) can be converted to the phenol portion by the use, for example, of hydrobromic acid or a mixture of hydrobromic acid and acid hydrobromic an acetic acid in the presence of NaHS03, to obtain an intermediate of the formula (SS) (III-2) or (SR) (III-2).
Suitable alternatives for (4R-frans) -4,5-dimethyl-2,2-dioxide-1, 3,2-dioxathiolane include the following chirally pure intermediates. in which LG is an exit group such as, for example, p-toluenesulfonyl. The intermediaries of the formula (III-2) by which the portion 2-hydroxy-1-methylpropyl has the form [R- (R *, R *)], intermediates that are represented by (RR) (III-a-2), can be prepared using the same reaction routes illustrated in scheme 2, although replacing (4R-fraps) -4,5-dimethyl-2,2-dioxide-1, 3,2-dioxathiolane with its enantiomer (4S-frans) -4,5-dimethyl-2,2-dioxide -1, 3,2-dioxatylane.
The intermediates of the formula (VI) can be prepared by reducing an intermediate of the formula (XIII) and then introducing an output group W3. Especially, the intermediates of the formula (VI) in which Alk is -CH (CH 3) -CH (CH 3) -, intermediates that are represented by the formula (V 1-a), can be prepared according to the reaction scheme illustrated in Scheme 3. Optionally, the chirally pure intermediates of the formula (Vl-a), represented by (SS) (Vl-a), (SR) (Vl-a), (RS) (VI-a) and (RR) (Vl-a), can be prepared using this procedure.

Said reduction conditions favor the threo form of the 2-hydroxy-1-methylpropyl moiety, that is, the way in which the two asymmetric carbon atoms have identical absolute configuration. The recrystallization of the intermediate of the formula (XVIII) obtained after the stereoselective reduction can further improve the threo / erythro ratio in favor of the threo form. The desired stereoisomeric forms of the intermediates of the formula (XVIII), which are (RR) (XVIII), (SS) (XVIII), (RS) (XVIII) and (SR) (XVIII), can then be isolated by chromatography using a chiral stationary phase such as, for example, Chiralpak AD (3,5-dimethylphenylcarbamate amylose) purchased from Daicel Chemical Industries, Ltd. of Japan. The intermediary of the formula (XVIII) or one or more of its stereoisomeric forms can then be further reacted with an intermediate of the formula (II) according to that described above for the general preparation of the compounds of the formula ( I '). Finally, the hydroxy group of the intermediates thus obtained of the formula (XIX) or a chirally pure form thereof can be converted to the appropriate leaving group W3, for example by derivatization of the hydroxy group with an organic acid such as, for example, a sulfonic acid, for example, p-toluenesulfonic acid or methanesulfonic acid to thereby obtain an intermediate of the formula (VII-a) or a chirally pure form thereof.

Other in vitro experiments, such as the determination of the effects of the present compounds on the synthesis of sterol in, for example, Candida albicans, also demonstrate their antifungal potential. In addition, in vivo experiments in various models of mice, guinea pigs and rats demonstrate that, after oral as well as intravenous administration, the present compounds are potent antifungals. Another advantage of some of the present compounds is that they are not only fungistatic, like most known azole antifungals, They are also fungicides in acceptable therapeutic doses against numerous fungal isolates. The compounds of the present invention are chemically stable and have good oral availability.

Therefore, compounds of the formula (I) are presented for use as a medicament, especially the use of a compound of the formula (I) in the preparation of a medicament used for the fungal treatment. The present invention also presents compositions for treating or preventing fungal infections containing an amount Therapeutically effective of a compound of formula (I) and a pharmaceutically acceptable carrier or diluent. By virtue of their advantageous pharmacological properties, the compounds in question can be formulated into various pharmaceutical forms for administration purposes.

These pharmaceutical compositions are conveniently presented in unit dosage form suitable, preferably, for administration orally, rectally, topically, percutaneously, transungueally or by parenteral injection. For example, when preparing the compositions in oral dosage form, any of the usual pharmaceutical means such as, for example, water, glycols, oils, alcohols and the like can be employed in the case of oral liquid preparations such as suspensions, syrups, elixirs and solutions; or solid vehicles such as starches, sugars, kaolin lubricants, binders, disintegrating agents and others in the case of powders, pills, capsules and tablets. Because of their ease of administration, tablets and capsules represent the most advantageous unit oral dosage form, in which case, solid pharmaceutical carriers are obviously employed. As Suitable compositions for topical application can be cited all the compositions usually used to administer drugs topically, for example creams, gels, compresses, shampoos, tinctures, ointments, salves, balsams, powders and others. In compositions suitable for percutaneous administration, the carrier optionally includes a penetration enhancing agent and / or a suitable wetting agent, optionally combined with suitable additives of any kind in minor proportions, additives that do not cause a deleterious effect of consideration in the skin. Said additives can facilitate administration to the skin and / or serve to prepare the desired compositions.

The transungual compositions are presented in the form of a solution and the vehicle optionally contains a reinforced penetration agent that favors the penetration of the antifungal into the keratinized nail layer and through the nail. The solvent medium consists of water mixed with a cosolvent such as an alcohol with 2 to 6 carbon atoms, for example ethanol. For parenteral compositions, the carrier usually consists of sterile water, at least in large part. For example, injectable solutions may be prepared in which the vehicle consists of saline, glucose solution or a mixture of saline and glucose solution. Injectable suspensions may also be prepared, in which case appropriate liquid carriers, suspending agents and the like can be used. For parepheral compositions, other ingredients can be included to contribute to solubility, for example cyclodextrins. Suitable cyclodextrins are a-, β- and β-cyclodextrins or ethers and mixed ethers thereof in which one or more of the hydroxy groups of the anhydroglucose units of the cyclodextrin are substituted with Ci 6 alkyl, especially methyl, ethyl or isopropyl, for example β-CD methylated at random, hydroxyalkyl Ci β, especially hydroxyethyl, hydroxypropyl or hydroxybutyl, C 6 -carboxyalkyl, especially carboxymethyl or carboxyethyl, C 6 -alkylcarbonyl, especially acetyl The β-CDs are noteworthy as complexing agents and / or solubilizers, the randomly-methylated CD-β, the 2,6-dimethyl-β-CD, the 2-hydroxide and the β-CD, the 2-hydroxide and the CD, 2-H? drox? prop? l -? - CD y (2-carbox? metho?) prop? l-β-CD, and especially 2-hydrox? prop? l-β-CD (2- HP-ß-CD) The term mixed ether indicates cyclodextrin derivatives in which at least two hydroxy groups of the cyclodextrin are etherified with different groups such as, for example, hydroxypropyl and hydroxyethyl. Medium molar substitution (MS) is used as a measure of the average number of moles of alkoxy units for each mole of anhydroglucose The mean substitution degree (DS) refers to the average number of substituted hydroxides for each anhydroglucose unit The MS and DS value can be determined by various analytical techniques such as resonance nuclear magnetic resonance (NMR), mass spectrometry (MS) and spectroscopy - Mftrtt ~ m? i infrared (IR). Depending on the technique used, different values can be obtained for a given cyclodextrin derivative. Preferably, as measured by mass spectrometry, the ranges of M.S. they fluctuate between 0.125 and 10 and the ranges of D.S. they range from 0.125 to 3. Other compositions suitable for oral or rectal administration contain particles which are obtained by melt extrusion of a mixture consisting of a compound of the formula (I) and an appropriate water soluble polymer and then milling said mixture extruded in fusion. These particles can then be formulated by conventional techniques to prepare pharmaceutical dosage forms such as tablets and capsules. Said particles consist of a solid dispersion constituted by a compound of the formula (I) and one or more pharmaceutically acceptable water soluble polymers. The preferred technique for preparing solid dispersions is the melt extrusion process which includes the following steps: a) mixing a compound of the formula (I) with an appropriate water-soluble polymer, b) optionally, mixing the additives with the mixture thus obtained, c) heating the mixture thus obtained to obtain a homogeneous melting, d) forcing the melt thus obtained through one or more nozzles and e) cool the melt until it solidifies. The solid dispersion product is ground or milled to obtain particles with a size of less than 600 μm, preferably less than 400 μm and most preferably less than 125 μm. The water-soluble polymers included in the particles are polymers having an apparent viscosity of 1 to 100 mPa when dissolved in a 2% aqueous solution at 20 ° C. For example, suitable water-soluble polymers include alkylcelluloses, hydroxyalkylcelluloses, hydroxyalkylalkylcelluloses, carboxyalkylcellulose, alkali metal salts of carboxyalkylcelluloses, carboxyalkylcelluloses, carboxyalkylcellulose esters, starches, pectins, chitin derivatives, polysaccharides, polyacrylic acids and salts thereof. , polymethacrylic acids and the salts thereof, copolymers of methacrylate, polyvinyl alcohol, polyvinylpyrrolidone, copolymers of polyvinylpyrrolidone with vinyl acetate, polyalkylene oxides and copolymers of ethylene oxide and propylene oxide. Preferred water-soluble polymers are hydroxypropylmethylcelluloses. One or more cyclodextrins can also be used as water-soluble polymers in the preparation of the mentioned particles, as described in WO 97/18839. Said cyclodextrins include the pharmaceutically acceptable unsubstituted and substituted cyclodextrins known in the art, more specifically the, β or β? cyclodextrins or pharmaceutically acceptable derivatives thereof.
Substituted cyclodextrins that may be used include the polyethers described in U.S. Patent No. 3,459,731. Other substituted cyclodextrins are the ethers in which the hydrogen of one or more hydroxy groups of the cyclodextrin is replaced by C1.6alkyl, C6.6 hydroxyalkyl, C5-carboxyalkyl, or C3-oxycarbonylalkylC1-, or the ethers mixed of them. In particular, those substituted cyclodextrins are ethers in which the hydrogen of one or more hydroxy groups of the cyclodextrin is replaced by C1.3 alkyl, C1-3 hiroxyalkyl or C1-3 carboxyalkyl or more specifically by methyl, ethyl, hydroxyethyl, hydroxypropyl , hydroxybutyl, carboxymethyl or carboxyethyl. Of particular utility are the β-cyclodextrin ethers, for example dimethyl-β-cyclodextrin, as described in Drugs of the Future, Vol. 9, No. 8, p. 577-578 by M. Nogradi (1984) and polyethers, for example hydroxypropyl β-cyclodextrin and hydroxyethyl β-cyclodextrin. That type of alkyl ether may consist of a methyl ether with a degree of substitution of about 0.124 to 3, for example from about 0.3 to 2. That hydroxypropylcyclodextrin can be formed, for example from the reaction between β-cyclodextrin and propylene oxide and can have an MS value of about 0.125 to 10, for example of about 0.3 to 3. A newer type of cyclodextrins is that of sulfobutylcyclodextrins. The ratio of active ingredient to cyclodextrin can vary widely. For example, 1/100 ratios can be applied to 100/1. Interesting ratios of the active ingredient with respect to the cyclodextrin are in the range of about 1/10 to 10/1. The most interesting ratios of active ingredient with respect to cyclodextrin are in the range of about 1/5 to 5/1. It may also be convenient to formulate the azole antifungals of the present invention in the form of nanoparticles consisting of a surface modifier adsorbed on the surface thereof in an amount sufficient to maintain an effective average particle size of less than 1000 nm. It is believed that useful surface modifiers include those that physically adhere to the surface of the antifungal agent but do not chemically bind to the antifungal agent. Suitable surface modifiers can be selected, preferably from known organic and inorganic pharmaceutical excipients. Such excipients include various polymers, low molecular weight oligomers, natural products and surfactants. Preferred surface modifiers include nonionic and anionic surfactants. Another interesting way of formulating the present compounds includes a pharmaceutical composition by which the antifungals of the present invention are incorporated into hydrophilic polymers and this mixture is applied as a coating film on very small beads, to thereby give a composition which can be elaborated conveniently andwhich is suitable for preparing pharmaceutical dosage forms for oral administration. Said beads are composed of a central, rounded or spherical core, a coating film of a hydrophilic polymer and an antifungal agent, as well as a polymeric layer sealing the coating. The materials suitable for use as cores in the beads are multiple, provided that said materials are pharmaceutically acceptable and have the appropriate dimensions and firmness. Examples of such materials include polymers, organic substances, inorganic substances and saccharides and derivatives thereof. The pharmaceutical compositions mentioned above may also contain an antifungally effective fungicidal amount such as active compounds for the cell wall. The term "active compound for the cell wall" used herein means any compound that interferes with the cell wall of the fungus and includes compounds such as papulacandins, echinocandins and aculeacins, as well as inhibitors of the cell wall of the fungus such as nikkomicins. , for example nikkomicin K and others described in U.S. Patent No. 5,006,513, but not limited thereto. It is especially advantageous to formulate the aforementioned pharmaceutical compositions in unit dosage form for ease of administration and uniformity of dosage. Form of unit dosage, term employed in the specification and the claims of the present refers to physically discrete units suitable as unit doses, each of which contains a predetermined quantity of active ingredient calculated to produce the desired therapeutic effect in combination with the vehicle Pharmaceutical necessary. Examples of such unit dosage forms are represented by tablets (including scored or coated tablets), capsules, pills, powder packets, stamps, injectable solutions or suspensions, tea spoons, soup spoons and the like, as well as segregated multiples of the same. Those skilled in the art of treating warm-blooded animals suffering from diseases caused by fungi could easily determine the therapeutically effective daily amount from the results of the tests presented herein. In general, it is considered that a therapeutically effective daily amount would be from about 0.05 mg / kg to 20 mg / kg of body weight.
