Description
BACKGROUND OF THE INVENTION
In U.S. Pat. No. 3,936,470 and Belg. Pat. No. 837,831 there are described a number of 1-(1,3-dioxolan-2-ylmethyl)-1H imidazoles and 1H-1,2,4-triazoles having antifungal and antibacterial properties. The compounds of this invention differ from the foregoing essentially by the substitution of the aryloxy-moiety with a heterocyclic group, the latter being attached to said aryloxy group by a carbon-carbon bond. Similar compounds wherein a heterocyclic radical is attached to the aryloxy group by a carbon-nitrogen bond are described in U.S. patent application Ser. No. 853,726, filed Nov. 21, 1977.

wherein said aryl as used in the foregoing definitions is selected from the group consisting of phenyl and substituted phenyl, said substituted phenyl having from 1 to 3 substituents each independently selected from the group consisting of halo, lower alkyl, lower alkyloxy and trifluoromethyl.
It is understood that radicals of formula (a) wherein R.sup.1 stands for hydroxy or mercapto may also exist under their tautomeric oxo, respectively thioxo, forms. Such oxo and thioxo forms, although not explicitely indicated in the above structures, are naturally intended to be within the scope of formula (I).
The preferred compounds of this invention are those where the radical Y is attached to the phenoxymethyl moiety in the para position.
As used in the foregoing and in following definitions, the term "halo" is generic to fluoro, chloro, bromo and iodo; "lower alkyl" is meant to include straight and branched hydrocarbon radicals having from 1 to 6 carbon atoms such as, for example, methyl, ethyl, 1-methylethyl, 1,1-dimethylethyl, propyl, 1-methylpropyl, 2-methylpropyl, butyl, pentyl, hexyl and the like; "lower alkenyl" and "lower alkynyl" are meant to include straight and branched alkenyl, respectively alkynyl, radicals having from 3 to 6 carbon atoms, wherein the unsaturation is preferably located at the 3-position, but can also be located at the .gamma., .delta. or .epsilon.-positions, such as, for example, 2-propenyl, 2-butenyl, 3-methyl-2-butenyl and the like, and, respectively 2-propynyl, 2-butynyl, 4-methyl-2-pentynyl and the like; and the term "cycloalkyl" designates cyclopropyl, cyclobutyl, cyclopentyl and cyclohexyl.
In order to simplify the structural representation of compounds (I) and of certain starting materials and intermediates used in the preparation thereof, the 2-Ar-2-(1H-imidazol-1-ylmethyl or 1-H-1,2,4-triazol-1-ylmethyl)-1,3-dioxolan-4-yl group, wherein Ar is as previously defined, will hereafter be represented by the formula D: ##STR7##
The compounds of formula (I) wherein Y is as previously defined, but other than a radical of formula (a) wherein R.sup.1 is hydroxy or mercapto, said Y being represented by Y.sup.1 and said compounds by the formula (I-a), can generally be prepared by the reaction of an appropriate reactive ester of the formula (II) with an appropriately substituted phenol of formula (III). ##STR8##
In formula (II), W has the meaning of a reactive ester residue such as, for example, halo, preferably chloro, bromo or iodo, or a sulfonyloxy group such as, for example, methylsulfonyloxy, 4-methylphenylsulfonyloxy and the like.
The reaction of (II) with (III) is carried out under art-known conditions of performing O-alkylations with reactive esters. The reaction is generally carried out in an appropriate reaction-inert organic solvent such as, for example, N,N-dimethylformamide, N,N-dimethylacetamide, hexamethylphosphoric triamide, dimethylsulfoxide, 4-methyl-2-pentanone and the like, optionally in admixture with other reaction inert solvents such as, for example, aromatic hydrocarbons, e.g., benzene, methylbenzene, dimethylbenzene and the like. Further it is advantageous to add to the reaction mixture an appropriate base such as, for example, an alkali metal hydride or carbonate, in order to enhance the rate of the reaction. Otherwise it may be advantageous to first convert the substituted phenol (III) into a metal salt thereof, preferably the sodium salt, in the usual manner, e.g., by the reaction of (III) with metal bases such as sodium hydride, sodium hydroxide and the like, and to use thereafter said metal salt in the reaction with (II). Somewhat elevated temperatures are appropriate to enhance the reaction rate and most preferably the reaction is carried out at from about 80.degree. C. to about 130.degree. C.
Compounds of formula (I) wherein Y has the formula (a) or (d), said Y being represented by Y.sup.2 and said compounds by the formula (I-b), can also be prepared by cyclizing an appropriate intermediate (IV) with an appropriate cyclizing agent and, if desired, introducing suitable substituents into the thus obtained heterocyclic compounds. ##STR9##

The reaction is carried out following the same reaction conditions as previously described for the preparation of compounds of formula (I-b-3), starting from (IV) and hydroxylamine.
Compounds of formula (I-b) wherein Y.sup.2 has the formula (a) wherein R.sup.1 is an acylamino radical of the formula NH--CO--R.sup.8, wherein R.sup.8 stands for lower alkyl or aryl, said compounds being represented by the formula (I-b-5), can be prepared by N-acylating a compound of formula (I-b-1) wherein R.sup.1.sub.a is amino, said compounds being represented by (I-b-1'), with an appropriate arylcarbonyl halogenide or lower alkylcarbonyl halogenide of the formula R.sup.8 --CO--halo, wherein halo is preferably chloro or bromo. ##STR14##
The reaction is conveniently carried out in the presence of a relatively polar organic solvent such as, for example, pyridine or 2,4,6-trimethylpyridine, preferably in the presence of a catalyst, e.g., N,N-dimethylpyridinamine, and most preferably at an elevated temperature in order to enhance the rate of the reaction.

The imidazole and triazole derivatives of formula (I), obtained in base form in the foregoing preparations, may be converted to their therapeutically useful acid addition salts by reaction with an appropriate acid, as, for example, an inorganic acid such as hydrohalic acid, i.e., kydrochloric, hydrobromic or hydroiodic acid; sulfuric, nitric or thiocyanic acid; a phosphoric acid; an organic acid such as acetic, propanoic, hydroxyacetic, 2-hydroxypropanoic, 2-oxopropanoic, ethanedioic, propanedioic, 1,4-butanedioic, (Z)-2-butenedioic, (E)-2-butenedioic, 2-hydroxy-1,4-butanedioic, 2,3-dihydroxy-1,4-butanedioic, 2-hydroxy-1,2,3-propanetricarboxylic, benzoic, 3-phenyl-2-propenoic, .alpha.-hydroxybenzeneacetic, methanesulfonic, ethanesulfonic, 2-hydroxyethanesulfonic, 4-methylbenzenesulfonic, 2-hydroxybenzoic, 4-amino-2-hydroxybenzoic, 2-phenoxybenzoic or 2-acetyloxybenzoic acid. The salts are in turn converted to the corresponding free bases in the usual manner, e.g., by reaction with alkali such as sodium or potassium hydroxide.
A number of the intermediates and starting materials used in the foregoing preparations are known compounds, others may be prepared according to art-known methodologies of preparing similar compounds and some of them are novel and consequently their preparation will be described hereafter.
The intermediates of formula (III) are generally known and they may all be prepared following methods described in the literature for preparing such known or similar compounds, such as, for example, the following.

The foregoing reactions are illustrated as follows: ##STR17##
The addition-reaction of (XI) with (XII) to produce a thiourea of formula (XIII) is carried out by stirring and heating the reactants together in a reaction-inert solvent such as, for example, a lower alcohol, preferably in the presence of an appropriate base such as, for example, a metal carbonate, e.g., potassium carbonate. The reaction of (XIII) with (XIV) is carried out following standard S-alkylating procedures, e.g., by stirring and heating the reactants together in an appropriate reaction-heat organic solvent such as a lower alcohol. The cyclization of (XV) is carried out in acid medium such as, for example, aqueous hydrochloric acid, at an elevated temperature during several hours. The hydrolysis of the methoxy-group of compound (XVI) is carried out by refluxing (XVI) for several hours in hydrobromic acid in glacial acetic acid.
2-(Methoxyphenyl)-1,3-dioxolane-2-methanamine (XI) may be prepared by ketalizing 2-[2-(methoxyphenyl)-2-oxoethyl]-1H-isoindole-1,3-(2H)-dione, (XVII), with ethanediol according to the procedures outlined in Synthesis, 1974 (I), 23 and thereafter subjecting the thus obtained dioxolane of formula (XVIII) to alkaline hydrolysis to liberate the primary amino group.

The foregoing reactions are illustrated as follows: ##STR19##
The cyclization-reaction is carried out by stirring the reactants together for several hours in a suitable polar solvent such as, for example, water, preferably in admixture with a water-miscible reaction-inert solvent such as, for example, 1,4-dioxane and the like or a lower alcohol, e.g., ethanol, most preferably at an elevated temperature in order to enhance the rate of the reaction. The S-alkylation reaction is carried out following standard S-alkylation methods and the hydrolysis of the lower alkylether is carried out following the previously described method for the hydrolysis of (XVI).

The desulfuration is carried out by art-known procedures, e.g., by stirring and heating the compounds of formula (XX) or (III-b) for several hours with Raney-nickel in an appropriate reaction-inert organic solvent such as, for example, a lower alcohol, e.g., ethanol and the like, preferably in the presence of a base, such as, for example, ammonia. In certain circumstances it may be appropriate to simultaneously introduce hydrogen into the reaction mixture. It is understood that said desulfurations may also be carried out using instead of a phenol a corresponding lower alkylether as a starting material and afterwards cleaving the ether group by acid hydrolysis as previously described herein.
The intermediates of formula (III) wherein Y.sup.1 has the formula (c) wherein R.sup.4 stands for hydrogen and G is NR.sup.5, said R.sup.5 being as previously defined and wherein the aryloxy-group is attached to the 5-position of the heterocyclic ring, said compounds being represented by the formula (III-a'), can be prepared by N-alkylating a compound of formula (III-b') wherein R.sup.5 stands for phenylmethyl, said compounds being represented by the formula (III-b'-1), with an appropriate reactive ester R.sup.5 -W, wherein R.sup.5 and W are as previously defined, following standard N-alkylating procedures to obtain a quaternary imidazolium salt of formula (XXII) and subsequently removing the phenylmethyl group of the latter in the usual manner, e.g., by catalytic hydrogenation in the presence of an appropriate catalyst such as, for example, palladium-on-charcoal. ##STR21##

The intermediates of formula (III) wherein Y.sup.1 has the formula (c) wherein R.sup.4 is as previously defined and G stands for S can generally be prepared following the procedures described in J. Am. Chem. Soc. 68, 871 (1946) and 67, 2242 (1945) and Helv. 44, 1429 (1961).
The compounds of formula (III) wherein Y.sup.1 has the formula (e) wherein R.sup.7 is as previously defined, said compounds being represented by the formula (III-d) can be prepared by the reaction of a hydroxybenzoic acid hydrazide of formula (XXV) with a tri(alkoxy)alkane of formula (XXVI). The reaction is carried out by stirring and heating the reactants together for several hours. ##STR25##
Intermediates of formula (II) wherein Q stands for CH and methods of preparing the same are described in Belg. Pat. No. 837,831. In general the reactive esters of formula (II) can be prepared along the following sequence of reactions.
An appropriate 1-Ar-2-bromoethanone of formula (XXVII) is subjected to a ketalization reaction with 1,2,3-propanetriol following methodologies analogous to those described in Synthesis 1974 (I), 23. In a preferred manner of carrying out the reaction both reactants are refluxed together for several hours with azeotropic water removal in an appropriate organic solvent, preferably in the presence of a simple alcohol, such as, for example, ethanol, propanol, butanol, pentanol and the like, and in the presence of an appropriate strong acid such as 4-methylbenzenesulfonic acid. Suitable organic solvents are, for example, aromatic hydrocarbons, such as benzene, methylbenzene, dimethylbenzene and the like and saturated hydrocarbons, such as cyclohexane.
The thus obtained dioxolane (XXVIII) is then reacted with benzoyl chloride to obtain a benzoate of the formula (XXLX) and the latter is subsequently reacted with 1H-imidazole or 1H-1,2,4-triazole. Said reaction is preferably carried out by stirring and heating the reactants together in a suitable organic solvent, e.g., N,N-dimethylformamide, in the presence of an appropriate strong metal base, e.g., sodium methanolate, to obtain an intermediate of the formula (XXX). The desired reactive esters of formula (II) are the conviently prepared by first hydrolyzing (XXX) in alkaline medium and thereafter converting the hydroxy group of the thus obtained (XXXI) into a reactive ester thereof according to methodologies generally known in the art. For example, methanesulfonates and 4-methylbenzenesulfonates are conveniently prepared by the reaction of the alcohol with methanesulfonyl chloride or 4-methylbenzenesulfonyl chloride and halides may be prepared by the reaction of the alcohol with an appropriate halogenating agent such as, for example, thionyl chloride, phosphor pentachloride, phosphor pentabromide, phosphoryl chloride and the like. When the reactive ester is an iodide, it is preferably derived from the corresponding choride or bromide by the replacement of that halogen with iodine.
The foregoing reactions may be illustrated as follows: ##STR26##
The intermediates of formula (IV) can be prepared by the reaction of a compound of formula (XXXII) with 1,1-dimethoxy-N,N-dimethylmethanamine. Said reaction is preferably carried out by stirring and heating the reactants together in the presence of a suitable organic solvent, e.g., N,N-dimethylformamide. ##STR27##
The starting materials of formula (XXXII) can be prepared by O-alkylating an appropriately substituted phenol of formula (XXXIII) with a reactive ester of formula (II), wherein W has the previously defined meaning, following the same procedure as described herein for the preparation of (I-a) starting from (II) and (III). ##STR28##
The ultimate starting materials in all of the foregoing preparations are generally known and they may all be prepared following methods described in the literature for the preparation of such known or similar compounds.
From formula (I) it is evident that the compounds of this invention have at least two asymmetric carbon atoms in their structures, namely those located in the 2- and 4-position of the dioxolane nucleus, and consequently they can exist under different stereochemically isomeric forms. The stereochemically isomeric forms of (I) and the pharmaceutically acceptable acid addition salts thereof are intended to be within the scope of this invention.
The diastereomeric racemates of (I), denoted as cis and trans forms respectively, according to the rules described in C.A., 76, Index Guide, Section IV, p. 85 (1972), may be obtained separately by conventional methods. Appropriate methods which may advantageously be employed therefore include, for example, selective crystallization and chromatographic separation, e.g. column-chromatography.
Since the stereochemical configuration is already fixed in the intermediates (II) and (IV) it is also possible to separate cis and trans forms at this or even an earlier stage, whereupon the corresponding forms of (I) may be derived thereform in the previously indicated manner. The separation of cis and trans forms of such intermediates may be performed by conventional methods as described hereabove for the separation of cis and trans forms of the compounds (I).
It is evident that the cis and trans diastereomeric racemates may be further resolved into their optical isomers, cis(+), cis(-), trans(+) and trans(-) by the application of methodologies known to those skilled in the art.
The compounds of formula (I) and the pharmaceutically acceptable acid addition salts thereof are useful agents in combatting fungi and bacteria. For example, said compounds and acid addition salts thereof were found to be highly active against a wide vareity of fungi such as, for example, Microsporum canis, Ctenomyces mentagrophytcs, Trichophyton rubrum, Phialophora verrucosa, Cryptococcus neoformans, Candida tropicalis, Candida albicans, Mucor species, Aspergillus fumigatus, Sporotricum schenckii and Saprolegnia species, and against bacteria such as, for example, Erysipelotrix insidiosa, Staphylococci such as Staphylococcus hemolyticus and Streptococci such as Streptococcus pyogenes. In view of their potent, local as well as systemic, antimicrobial activity the compounds of this invention constitute useful tools for the destruction or prevention of the growth of fungi and bacteria and more particularly they can effectively be used in the treatment of subjects suffering from such microorganism.
The strong antimicrobial activity of the compounds (I) is clearly evidenced by the data obtained in the following experiments, which data is only given to illustrate the useful antimicrobial properties of all the compounds (I) and not to limit the invention either with respect to the scope of susceptible microorganisms nor with respect to the scope of formula (I).
Experiment A: Activity of compounds (I) against vaginal candidosis in rats.
Female Wistar rats of .+-.100 g body weight are used. They are ovariectomized and hysterectomized and after three weeks of recovery, 100 .mu.g of oestradiol undecylate in sesame oil is given subcutaneously once a week for 3 consecutive weeks. The thus induced pseudooestrus is controlled by microscopic examination of vaginal smears. Food and water are left available ad libitum. The rats are infected intravaginally with 8.10.sup.5 cells of Candida albicans, grown on Sabouraud broth for 48 hours at 37.degree. C. and diluted with saline. The date of infection varies from day +25 to day +32 after surgical intervention, depending on the appearance of signs of induced pseudo-oestrus.
The drugs under investigation are administered orally once a day for two days starting from the day of infection. For each experiment there are placebo treated controls. The results are assessed by taking vaginal smears with sterile swabs on several days after the infection. The swabs are put into Sabouraud broth in petri-dishes and incubated for 48 hours at 37.degree. C. If no growth of Candida albicans occurs, i.e., when the animals are negative at the end of the experiment, this is due to drug administration because it never happens in placebo treated controls.
The table below gives the lowest oral dose of the drug under investigation which is found active at the 14th day after infection.
Experiment B: Activity of compounds (I) against crop candidosis in turkeys.
Turkeys of 14 days old are infected in the crop with 4.10.sup.6 Candida albicans cells, grown on Sabouraud broth for 48 hours at 37.degree. C. and diluted with saline. The volume of the inoculum is 1 ml. The drugs under investigation are premixed in 500 mg of lacton and thereafter admixed in 1000 g of meal without any additives. The concentration of the drug under investigation in the meal is expressed in mg/kg.
The animals are given the medicated feed for 13 consecutive days starting on the day of infection. At the end of the experiment all animals are sacrificed. At autopsy the crops are removed, emptied and grinded in an ultra-turrax mixer in 15 ml of sterile saline. Colony counting is done on Sabouraud agar and the results given in the table represents the ED.sub.50, i.e., the dose of the drug whereby the crops of 50% of the animals are completely negative for Candida albicans.
The compounds listed in the Table are intended to illustrate and not to limit the scope of the present invention.
In view of their antifungal and antibacterial properties this invention provides valuable compositions comprising the subject compounds of formula (I) or acid addition salts thereof as the active ingredient in a solvent or a solid, semi-solid or liquid diluent or carrier, and, in addition, it provides an effective method of combatting fungal or bacterial growth by use of an effective antifungal or antibacterial amount of such compounds (I) or salts thereof. Antifungal and antibacterial compositions comprising an effective amount of an active compound (I), either alone or in combination with other active therapeutic ingredients, in admixture with suitable carriers may be readily prepared according to conventional pharmaceutical techniques for the usual routes of administration.
Preferred compositions are in dosage unit form, comprising per dosage unit an effective quantity of the active ingredient in admixture with suitable carriers. Although the amount of the active ingredient per unit dosage may vary within rather wide limits, dosage units comprising from about 50 to about 500 mg and more particularly from about 100 to about 250 mg of the active ingredient are preferred.
