The compounds of formula I contain one or more basic nitrogen atoms and, consequently, they can form salts with acids, which are also included in the present invention. There is no limitation on the nature of these salts, provided that, when used for therapeutic purposes, they are pharmaceutically acceptable, which, as is well-known in the art, means that they do not have reduced activity (or unacceptable reduced activity) or increased toxicity (or unacceptable increased toxicity) compared with the free compounds. Examples of these salts include: salts with an inorganic acid such as hydrochloric acid, hydrobromic acid, hydriodic acid, nitric acid, perchloric acid, sulfuric acid or phosphoric acid; and salts with an organic acid, such as methanesulfonic acid, trifluoromethanesulfonic acid, ethanesulfonic acid, benzenesulfonic acid, p- toluenesulfonic acid, fumaric acid, oxalic acid, maleic acid; and other mineral and carboxylic acids well known to those skilled in the art. The salts are prepared by reacting the free base with a sufficient amount of the desired acid to produce a salt in the conventional manner. Free bases and their salts differ in certain physical properties, such as solubility, but they are equivalent for the purposes of the invention. Some compounds of the present invention can exist in solvated form, including hydrated forms. In general, the solvated forms, with pharmaceutically acceptable solvents such as water, ethanol and the like, are equivalent to the unsolvated forms for the purposes of the invention. The compounds of formula I contain one or more asymmetric carbons and, consequently, can exist as different stereoisomers. The present invention covers both each of the individual stereoisomers and their mixtures. When R l is C 1 -C 4 alkyl and R 2 is hydrogen, those compounds of formula I wherein the absolute configuration of the carbon atoms to which the Ar and Ri groups are bonded is (R,R) are preferred, i.e. compounds of formula: Diastereoisomers can be separated by conventional techniques such as chromatography or fractional crystallization. The optical isomers can be resolved using any of the conventional techniques of optical resolution to give optically pure isomers. Such a resolution can be performed in any chiral synthetic intermediate as well as in the products of general formula I. The optically pure isomers can also be individually obtained using enantiospecific synthesis. We have obtained the optically pure (R,R) isomers starting from optically pure amine II, prepared following the general procedure described in J.Org.Chem, 1995, 60, 3000-3012. As stated above, the present invention covers the individual isomers as well as their mixtures (e.g. racemic mixtures), whether as obtained by synthesis or by physically mixing them up. Some of the compounds of formula I may present tautomerism. For example, when the compounds of the present invention contain an amidino group of formula -C(=NR o )NHRn, the following tautomeric structures may exist in equilibrium: all of which are encompassed by the present invention. The compounds of formula I can be prepared using the procedures described below. The precise method used for the preparation of a given compound may vary depending on its chemical structure. The compounds of formula I can be prepared by reacting an amine of formula II with an acid of formula III in the presence of an appropriate condensing agent, for example dicyclohexylcarbodiimide, alone or in combination with 1-hydroxybenzotriazole, in a polar solvent, such as a substituted amide (for example N-methylpyrrolidone or dimethylformamide), an ether (for example tetrahydrofuran or dioxane) or diglyme, at a temperature preferably comprised between 0°C and 100°C. Alternatively, compounds of formula I can be prepared by reacting an amine II with a reactive derivative of an acid III, such as the acid chloride, anhydride or mixed anhydride. The reaction is carried out in the presence of a proton scavenger base, such as triethylamine or pyridine, in a suitable solvent such as dichloromethane or chloroform. Alternatively, compounds of formula I wherein Y represents -O-, -S- or -NR 6 - and m is 0 can be prepared from the corresponding compound wherein A is substituted with a halogen atom, for example bromine, instead of a group -Y(CH 2 )q-B by treatment with an alkaline metal salt of the corresponding alcohol or thiol of formula HY(CH 2 )q-B, for example the sodium salt, or by treatment with an amine of formula HNR 6 (CH 2 )q-B in a suitable aprotic solvent such as N-methylpyrrolidone at a temperature between room temperature and that of the refluxing solvent. Moreover, some compounds of formula I can also be prepared by interconversion from another compound of formula I in one or a plurality of steps using reactions well known in organic chemistry, such as the reactions listed below. These reactions are mentioned here only as illustrative examples of the several procedures which can be used to interconvert compounds of the present invention and are not intended to limit the scope of the preparation of compounds of formula I in any way. Thus, for example, the compounds of formula I wherein R 3 together with R 4 and the remainder of said compound of formula I form a morpholine ring of formula I", wherein D is hydrogen and the dotted line is absent, can be prepared from the corresponding compound of formula I wherein R3= -(CH 2 ) 2 OH by treatment with diethylazadicarboxylate and tributylphosphine in a suitable solvent such as tetrahydrofuran. The compounds of formula I wherein R 3 together with R 4 and the remainder of said compound of formula I form a morpholine ring of formula I", wherein D is hydroxy and the dotted line is absent, can be prepared from the corresponding compound of formula I wherein R 3 = -(CH ) OH by oxidation for example by treatment with activated DMSO and a base, such as triethylamine, in a suitable solvent, such as dichloromethane or chloroform. The compounds of formula I wherein R3 together with R 4 and the remainder of said compound of formula I form a morpholine ring of formula I", wherein D is O and the dotted line represents a covalent bond, can be prepared from the corresponding compound of formula I wherein R 3 = -CH 2 COOH using a suitable dehydrating agent or alternatively they can be prepared from the corresponding compound of formula I wherein R 3 = -(CH 2 hOH by overoxidation. Furthermore, it is also possible to convert a group R 3 in a compound of formula I into another group R 3 using standard methods of organic synthesis . Thus, a benzyl ether can be converted to the corresponding alcohol by hydrogenation in the presence of a suitable catalyst such as Pd/C in a suitable solvent such as an alcohol at a hydrogen pressure between 1 and 5 atm. An ester group can be hydrolized to the corresponding acid using conventional procedures; in case of benzyl esters, this conversion can be carried out by hydrogenation in the same experimental conditions mentioned above. An ester group can also be reduced by treatment with a suitable metal hydride such as sodium borohydride in a suitable solvent such as ethanol to give the corresponding alcohol. It is also possible to use a group B in a compound of formula I to generate other groups B thus giving rise to other compounds of formula I. For example, a nitro group can be reduced to an amino group, for example by hydrogenation in the presence of a catalyst such as Pd/C in a suitable solvent such as an alcohol, for example ethanol, at a temperature between room temperature and that of the refluxing solvent and at a pressure preferably between atmospheric pressure and 10 atm. A thioether group can be oxidized to a sulfinyl or sulfonyl group by treatment with a suitable oxidising agent. For example, a thioether group can be oxidized to a sulfonyl group by treatment with -chloroperbenzoic acid in a suitable solvent such as a halogenated hydrocarbon at a temperature preferably between 0°C and room temperature. Moreover, an amino group can be converted to a group of formula (i) by treatment with phenyl chloroformate, subsequent reaction of the phenyl carbamate thus obtained with hydrazine and finally cyclisation of the resulting semicarbazide with formamidine or acetamidine in a suitable solvent such as dimethylformamide at a temperature between room temperature and that of the refluxing solvent. A nitrile group can be converted to a tetrazole group by treatment with a suitable azide such as sodium azide or ammonium azide (which may be prepared in situ from sodium azide and ammonium chloride) in a suitable solvent such as a polar solvent, for example dimethylformamide or N-methylpyrrolidone, at a temperature preferably between room temperature and that of the refluxing solvent. Another example of interconversion is the N-alkylation of a group of formula (i) or a tetrazole by treatment with the corresponding alkyl halide in the presence of a base such as potassium or cesium carbonate in a suitable aprotic solvent such as dimethylformamide. A nitrile group can be hydrolized to a carbamoyl group by treatment with ammonium hydroxide in a suitable solvent such as tetrahydrofuran-water mixtures under reflux. A nitrile group can also be converted to an alkyl imidate group by bubbling HCl gas in an alcohol, such as methanol. An alkyl imidate group can also be converted to an amino(imino)methyl group by reaction with an amine using the corresponding alkanol as solvent. Moreover, a halogen atom, for example bromo or iodo, can be converted to a phenyl group by a coupling reaction between the corresponding haloderivative and a boronic acid or ester of formula (RO^B-phenyl (wherein R represents hydrogen or C 1 -C 4 alkyl) in the presence of a palladium catalyst such as Pd(OAc) 2 or Pd(PPh 3 ) 4 in a suitable solvent such as dimethoxyethane at a temperature preferably between room temperature and that of the refluxing solvent. A halogen atom, for example a fluorine atom, can be converted into a C 1 -C 4 alkoxy, C 1 -C 4 haloalkoxy, phenoxy, -SR 10 , triazole or imidazole group by treatment with an alkaline metal salt of the corresponding alcohol, thiol, triazole or imidazole, for example the sodium salt, in a suitable aprotic solvent such as N- methylpyrrolidone at a temperature between room temperature and that of the refluxing solvent; moreover, it can also be converted into an amine (-NR 6 R7, 1-pyrrolidine, morpholine, a group of formula (ii) or a group of formula (iii)) by treatment with the corresponding amine in a suitable aprotic solvent such as N-methylpyrrolidone at a temperature between room temperature and that of the refluxing solvent. Furthermore, a compound of formula I wherein Y represents -SO- or -SO 2 - can be prepared from the corresponding compound of formula I wherein Y is -S- by oxidation as described above in connection with group B. As it will be apparent to those skilled in the art, these interconversion reactions can be carried out both on the final products of formula I or on any synthetic intermediate thereof. Amines of formula II can be prepared as described in J.Org.Chem, 1995, 60, 3000-3012, EP 332387 or EP 617031. Acids of formula III or derivatives thereof are commercially available, widely described in the literature or can be prepared by methods analogous to those known in the art.

The present invention further provides compositions that contain a compound of the present invention, together with an excipient and optionally other auxiliary agents, if necessary. The compounds of the present invention can be administered in different pharmaceutical preparations, the precise nature of which will depend, as it is well known, upon the chosen route of administration and the nature of the pathology to be treated. Thus, solid compositions according to the present invention for oral administration include compressed tablets, dispersible powders, granules and capsules. In tablets, the active component is admixed with at least one inert diluent such as lactose, starch, mannitol, microcrystalline cellulose or calcium phosphate; granulating and disintegrating agents for example corn starch, gelatine, microcrystalline cellulose or polyvinylpyrrolidone; and lubricating agents for example magnesium stearate, stearic acid or talc. The tablets may be coated by known techniques to delay disintegration and absorption in the gastrointestinal tract and, thereby, provide a sustained action over a longer period. Gastric film-coated or enteric film-coated tablets can be made with sugar, gelatin, hydroxypropylcellulose, or acrylic resins. Tablets with a sustained action may also be obtained using an excipient which provides regressive osmosis, such as the galacturonic acid polymers. Formulations for oral use may also be presented as hard capsules of absorbable material, such as gelatin, wherein the active ingredient is mixed with an inert solid diluent and lubricating agents, or pasty materials, such as ethoxylated saturated glycerides. Soft gelatin capsules are also possible wherein the active ingredient is mixed with water or an oily medium, for example peanut oil, liquid paraffin or olive oil. Dispersible powders and granules suitable for the preparation of a suspension by the addition of water provide the active ingredient in admixture with a dispersing or wetting agent; a suspending agent, such as sodium carboxymethylcellulose, methylcellulose, hydroxypropyl- methylcellulose, sodium alginate, polyvinylpirrolidone, gum tragacanth, xantham gum, gum acacia, and one or more preservatives, such as methyl or n-propyl p-hydroxybenzoate. Additional excipients, for example sweetening, flavoring and coloring agents may also be present. Liquid compositions for oral administration include emulsions, solutions, suspensions, syrups and elixirs containing commonly used inert diluents, such as distilled water, ethanol, sorbitol, glycerol, or propylene glycol. Aqueous solutions can also be prepared using β-cyclodextrins, such as hydroxypropyl-β-cyclodextrin. Such compositions may also comprise adjuvants such as wetting agents, suspending agents, sweetening, flavoring, perfuming, preserving agents and buffers. Other compositions for oral administration include spray compositions, which may be prepared by known methods. The spray compositions will contain a suitable propellent. Preparations for injection, according to the present invention, for parenteral administration include sterile aqueous or non-aqueous solutions, suspensions or emulsions, in a non-toxic parentally-acceptable diluent or solvent. Examples of aqueous solvents or suspending media are distilled water for injection, Ringer's solution, and isotonic sodium chloride solution. Aqueous solutions can also be prepared using β-cyclodextrins, such as hydroxypropyl-β-cyclodextrin. Examples of non-aqueous solvents or suspending media are propylene glycol, polyethylene glycol, vegetable oils such as olive oil, or alcohols such as ethanol. These Compositions may also include adjuvants such as wetting, preserving, emulsifying and dispersing agents. They may be sterilized by one of the known methods or manufactured in the form of sterile solid compositions which can be dissolved in sterile water or some other sterile injectable medium immediately before use. When all of the components are sterile, the injectables will maintain the sterility if they are manufactured in sterile environment. Preparations for vaginal administration according to the present invention include tablets, capsules, softgels, moulded pessaries, creams, foams and vaginal douches. Vaginal tablets provide the active component in admixture with lactose, microcrystalline cellulose, pregelatinized starch, polyvidone and magnesium stearate as typical excipients. Soft gelatin capsules (softgels) can be made dispersing the active ingredient in an oily medium, for example liquid paraffin, dimethylpolysiloxane 1000 or hydrogenated soybean oil. Moulded pessaries provide the active ingredient in admixture with a suitable synthetic or semisynthetic base (such as Suppocire® or Novata® types). Low viscosity saturated Cβ to Cι 2 fatty acid glycerides and colloidal silice are also added to improve incorporation and to prevent sedimentation of the active ingredient. Vaginal creams can be prepared as emulsions, with sufficient viscosity to retain their integrity and adhere to the vaginal cavity. Neutral fats, fatty acids, waxes, mineral oils and fatty acid esters can be used as the oily phase. Water, glycerine, sorbitol solution and polyethylene glycol are suitable excipients for the aqueous phase. Non-ionic emulsifying agents like polyethylene glycol ethers may also be used, and such compositions may also contain preserving, buffering and stiffening agents. Foaming systems can be made using a foamer (dispenser) that is able to transform a solution into a foam. Such systems may include cosolvents, buffers, preservatives, foam stabilizers and perfumes in an aqueous vehicle. Vaginal douches may contain cosolvents, preservatives, buffers and perfuming agents in a surfactant rich aqueous solution. A compound of the invention may also administered in the form of suppositories for rectal administration of the drug, or as creams, ointments, pastes, lotions, gels, sprays, foams, aerosols, solutions, suspensions or powders for topical use. Such compositions are prepared following conventional procedures well known to those skilled in the art. A compound of the invention may also be administered as a hair or body shampoo. These formulations may be prepared using suitable ionic and/or amphoteric surface-active agents such as sodium laureth sulfate, triethanolamine laureth sulfate, cocoamidopropyl betaine; thickening agents for example cocamide DEA, carbomer, sodium chloride and polyethylene glycol 6000 distearate; and optionally, emolient and superfatting agents, buffers, and preserving and perfuming agents. The dosage and frequency of dose may vary depending upon the nature and severity of the fungal disease, symptoms, age and body weight of the patient, as well as upon the route of administration. In general, the compounds of the invention will be administered orally or parenterally at a dosage ranging from 0.01 mg/Kg/day to 100 mg/Kg/day, which can be administered as a single dose or as divided doses. Following are some representative preparations for tablets, capsules, syrups, aerosols and injectables.
