Description: Novel Bicyclic Compounds The present invention relates to novel bicyclic compounds having N- myristoyltransferase (hereinafter referred to as NMT) inhibitory activity and antifungal activity, processes for producing the same, the use in the medical therapy of said compounds and pharmaceutical compositions containing said compounds. NMT is an enzyme that transfers cellular fatty acid myristate from myristoyl CoA to the N-terminal glycine of eukaryotic cellular proteins. N- myristoylation of several G-proteins, Gpal, Arfl, Arf2 and Vpslδ, which are essential for fungal growth, have been reported to be indispensable for their function in Saccharomyces cerevisiae (K. J. Lodge et al., Proc. Natl. Acad. Sci., Vol. 91, PP. 12008-12012, 1994; D. R. Johnson et al., Annu. Rev. Biochem., Vol. 63, PP. 869-914, 1994; Stearns T. et al., Mol. Cell Biol., Vol.10, PP. 6690- 6699, 1990; P. K. Harman et al., Cell, Vol. 64, PP. 425-437, 1991). Genetic studies have also demonstrated that this enzyme is essential for the viability of the fungi including medically important pathogenic fungi. For example, the essentiality of the enzyme in S. cerevisiae has been reported by Robert J. Duronio et al. (Proc. Natl. Acad. Sci., Vol. 89, pp. 4129-4133, 1992), the essentiality in Candida albicans has been reported by Robin A. Weiberg et al. (Molecular Microbiology, Vol. 16, PP. 241-250, 1995), and the essentiality in Cryptococcus neoformans has been reported by K. J. Lodge et al. (Proc. Natl. Acad. Sci., Vol. 91, pp. 12008-12012, 1994).

A further process of the present invention comprises a process for producing bicyclic compounds of the formula [I] as defined above which comprises alkylating a compound of the formula [V], wherein R 1 , R 2 , R 3 , R 4 , and R 5 are the same as defined in claim 1, with an alkylating agent of the formula [X] , HO-Q 1 - J] -Q 2 -R 6 [X] wherein Q 1 , Q 2 and R 6 are the same as defined above, and alkylating the resulting compound of the formula [XI] wherein R 1 , R 2 , R 3 , R 4 , R 5 , R 6 and Q 1 are the same as above, with an alkylating agent of formula [XII], 0 [XII] 12 R R' wherein R 12 is hydrogen or lower alkyl, and R 7 is the same as defined above, or with an alkylating agent [XIII] Halo-R 92 [XIII] wherein Halo is halogen and R 92 is unsubstituted or substituted lower alkyl, aralkyl, cycloalkyl or cycloalkylalkyl. In more detail, the compound of the present invention may be prepared as follows: Process 1 Compounds of the following formula [II] (in which R n is hydrogen, unsubstituted lower alkyl, aralkyl, cycloalkyl or cycloalkylalkyl) and of the formula [III] (in which R u is hydrogen, unsubstituted lower alkyl, aralkyl, cycloalkyl or cycloalkylalkyl, and one of R 3 , R 4 and R 5 is halogen) can be the starting materials for the synthesis of compounds of the formula [I] defined as above. Compounds of the formula [II] (in which R u is hydrogen) can be prepared by the method reported by S. Yamaguchi et al., Bull. Chem. Soc. Jpn., Vol. 62, 4066-4068 (1989). Compounds of the formula [II] (in which R 11 is hydrogen, unsubstituted lower alkyl, aralkyl, cycloalkyl or cycloalkylalkyl) and of the formula [III] (in which R 11 is hydrogen, unsubstituted lower alkyl, aralkyl, cycloalkyl or cycloalkylalkyl, and one of R 3 , R 4 and R 5 is halogen) can be prepared according to the following Flow Chart 1: PG in Flow Chart 1 means a protective group such as methoxy ethyl. Compound of the formula [II] (in which R u is hydrogen, unsubstituted lower alkyl, aralkyl, cycloalkyl or cycloalkylalkyl) can be prepared from compound 4 by practically the same method as described in EP 0146243 (J. G. Atkinson et al.,). When R π is methyl, compound 4 is commercially available (e.g. Wako Pure Chemical Industries, Ltd.). When R π is not hydrogen or methyl, compound 4 can be prepared from resorcinol 1 via compounds 2 and 3. Resorcinol 1 is commercially available (e.g. Wako Pure Chemical Industries, Ltd.). For example, compound 1 is converted into compound 2 by treating compound 1 with a base such as NaH and then methoxymethyl chloride in an inert solvent such as N,N-dimethylformamide. Compound 2 is acylated by a similar method to the literature (V. Snieckus et al, Chem. Rev. Vol.90, pp. 879- 933 (1990)). Compound 2 is then treated with a base such as butyl lithium and then the obtained anion is treated with various acyl halides to give compound 3. The treatment of compound 3 with an acid such as hydrochloric acid gives compound 4. Compound of the formula [II] (in which R 11 is hydrogen, unsubstituted lower alkyl, aralkyl, cycloalkyl or cycloalkylalkyl) can be converted into compound of the formula [III] (in which R 11 is hydrogen, unsubstituted lower alkyl, aralkyl, cycloalkyl or cycloalkylalkyl, and one of R 3 , R 4 and R° is halogen) by known methods per se. For example, when bromine is used as a reagent (J. G. Atkinson et al., EP 0146243), bromination occurs at position 5 to give compound of the formula [III] (in which R u is hydrogen, unsubstituted lower alkyl, aralkyl, cycloalkyl or cycloalkylalkyl, R 3 is bromo, and R 4 and R 5 are hydrogen). When N-fluoro-2,5-dichloropyridinium tetrafluoroborate is used as a reagent (T. Umemoto et al, J. Org. Chem. Rev. Vol. 60, pp. 6563-6570 (1995)), fluorination occurs at position 5 or position 7 to give compound of the formula [III] (in which R 11 is hydrogen, unsubstituted lower alkyl, aralkyl, cycloalkyl or cycloalkylalkyl, R 3 is fluoro, and R 4 and R 5 are hydrogen) and compound of the formula [III] (in which R u is hydrogen, unsubstituted lower alkyl, aralkyl, cycloalkyl or cycloalkylalkyl, R 5 is fluoro, and R 3 and R 4 are hydrogen). Process 2 Compounds of the formula [I] (in which R 2 is unsubstituted or substituted lower alkyl such as ethyl, propyl, butyl, CH 2 OH, CH 2 OEt or CH 2 NH 2 ) can be prepared according to the following Flow Chart 2: Flow Chart 2 Q a in Flow Chart 2 is as defined above or a radical that can be converted into by known methods per se or one of the methods selected from Flow Chart 7, Flow Chart 8 and Flow Chart 9 hereinafter. R la is the same as R 1 defined above or a radical that can be converted into R 1 by known methods per se or one of the methods selected from Flow Chart 3, Flow Chart 4, Flow Chart 5, Flow Chart 6 and Flow Chart 10 hereinafter. R 21 is unsubstituted lower alkyl, aralkyl, cycloalkyl or cycloalkylalkyl. R 22 is unsubstituted lower alkyl, aralkyl, cycloalkyl or cycloalkylalkyl. Q 1 , Q 2 , Q 3 , R 3 , R 4 , R 5 , R 6 and R 7 , are the same as defined above. Alkylation of compound 6 to obtain compound 10 can be carried out as follows: 1) Compound 6 is treated with a base such as lithium diisopropylamide in an inert solvent such as tetrahydrofuran, 2) and then the obtained anion is treated with lower alkyl halide such as methyl iodide, ethyl bromide and n-propyl bromide. Bromination of compound 6 to obtain compound 7 can be carried out by reacting compound 6 with N-bromosuccinimide in an inert solvent such as carbon tetrachloride. Compound 7 is converted into an azide derivative by the reaction with sodium azide in an inert solvent such as N,N- dimethylformamide. Hydrogenolysis of the azide gives amine 11. Hydrogenolysis can be carried out under standard conditions known in the art, for example Pd on carbon is used as a catalyst. Hydrolysis and alcoholysis of compound 7 gave hydroxy derivative 8 and alkoxy derivative 9, respectively. R 1 in the formula [I] can be modified by one of the methods described in the following Flow Chart 3, Flow Chart 4, Flow Chart 5, Flow Chart 6 and Flow Chart 10 hereinafter. Process 3 Flow Chart 3 In Flow Chart 3, Q a is or a radical which can be converted into by known methods per se or by one of the methods described in Flow Chart 7, Flow Chart 8 and Flow Chart 9 hereinafter. R 2a is R 2 or a radical which can be converted into R 2 by known methods per se or by one of the methods described in Flow Chart 2. R 8a is unsubstituted or substituted lower alkyl, aralkyl, cycloalkyl, cycloalkylalkyl. R 8b is unsubstituted or substituted aromatic ring, or lower alkyl substituted by fluorine atoms such as 2, 2, 2-trifluoroethyl. R 31 is lower alkyl, aralkyl, cycloalkyl, cycloalkylalkyl or an aromatic ring which can be further substituted by fluoro, chloro, lower alkyl and lower alkoxy. TFA is trifluoroacetic acid. Q 1 , Q 2 , Q 3 , Q 5 , R 3 , R 4 , R 5 , R 6 , R 7 , R 8 , R 9 and R 10 are the same as defined above. Compound 12 is reduced by a known reducing agent such as lithium aluminium hydride to give an alcohol derivative 13. Various amide derivatives can be prepared by the standard methods per se. For example, compound 12 is directly aminated to give amide 20 by heating the compound 12 together with an appropriate amine, NHR 9 R 10 . Amide 20 can also be prepared by the coupling of acid 19, which is obtained from ester 12 by alkaline hydrolysis, with desired amine NHR 9 R 10 . Various coupling reagents such as thionyl chloride and water soluble carbodiimide can be used for the coupling (for example, refer to E. Gross et al. "The peptides", Academic Press, 1979). Amide 20 can be converted into thioamide 21 by Lawesson's reagent (M. P. Cava et al. Vol. 41, PP. 5061-5087, 1985). The compound 13 is further converted into ether 15 by the reaction with 1) a base such as NaH and 2) halogen-R 8a (in which R 8a is unsubstituted or substituted lower alkyl, aralkyl, cycloalkyl, cycloalkylalkyl) in an inert solvent such as tetrahydrofuran. Compound 13 is also converted into ether derivative 14 (wherein R 8b is unsubstituted or substituted aromatic ring, or lower alkyl substituted by fluorine atoms such as 2, 2, 2-trifluoroethyl) by Mitsunobu reaction (for example, O. Mitsunobu, Synthesis PP. 1-28, 1981 and J. R. Falck et al., Tetrahedron Letters, Vol. 35, PP. 5997-6000, 1994) in an inert solvent such as tetrahydrofuran and benzene. Various phosphines such as trimethylphosphine, tributylphosphine and triphenylphosphine and various azodicarbonyl compounds such as azodicarboxylic acid diethyl ester, l,l'-(azodicarbonyl)dipiperidine and 1,1'- azobis(.N,Λ -dimethylformamide) can be used for Mitsunobu reaction. Compound 13 is also converted into thioether derivative 16 by the treatment of compound 13 with desired thiol, HSR 8 , in the presence of acid such as trifluoroacetic acid. Thioether 16 is oxidised to give sulfoxide 17 by bis(2,4- pentanedionato)vanadium oxide or per acid such as m-chloroperbenzoic acid. Sulfone 18 can be obtained by oxidising thioether 16 with bis(2,4- pentanedionato)vanadium oxide (C. Bolm et al., Angew. Chem., Int. Ed. Engl. Vol. 34, PP. 2640-2642, 1995). Esterification of compound 19 to compound 22 can be carried out by the treatment of compound 19 with a base such as potassium carbonate and alkyl halide, R 8a -halogen, or the condensation of compound 19 and alcohol, R 8a OH, in the presence of a coupling reagent such as water-soluble carbodiimide. Compound 19 can be converted into ketone 23 by practically the same method as that reported by S. Nahm and S. M. Weinreb (Tetrahedron Letters, Vol. 22, PP 3815-3813, 1981). Hydrazides 56a and 56b are prepared from acid 19 by the reaction with hydrazine or hydrazide, , in the presence of a coupling reagent such as water soluble carbodiimide. When Q 5 is a single bond and R 9 is hydrogen, both 56a and 56b can be prepared by this method. When Q 5 is carbonyl, only 56a is prepared by the method. When neither Q 5 -R 9 nor R 10 is hydrogen, only 56a is prepared by the method. Process 4 Flow Chart 4 In Flow Chart 4, Q a is or a radical which can be converted into by known methods per se or by one of the methods described in Flow Chart 7, Flow Chart 8 and Flow Chart 9 hereinafter. R 2a is R 2 or a radical which can be converted into R 2 by known methods per se or by one of the methods described in Flow Chart 2. Q\ Q 2 > Q 3 > R 3 , R\ R°, R 6 > R 7 , R 8 and R 9 are the same as defined above. Compound 19 can be converted into compound 24 by the reaction with a bromination reagent such as pyridinium tribromide (O. H. Hankovszky et al., Synthesis, P91, 1991). The obtained bromide 24 is phosphonated by the reaction with trialkylphosphite in the presence of palladium catalyst such as tetrakis(triphenylphosphine)palladium and with tertiary amine such as triethylamine in an inert solvent such as toluene to give compound 25. Process 5 Introduction of heterocyclic ring at position 2 of the benzofuran ring can be carried out by various methods. For example, oxazole, dihydrooxasole and thiazole can be introduced by the methods described in Flow Chart 5.

This inhibitory activity indicates that the compounds of the formula [I] and pharmaceutically acceptable salts thereof can be antimycotic agents. The bicyclic compounds of the formula [I] and pharmaceutically acceptable salts thereof are very active antimycotic agents. They are active against a variety of fungal species including Candida albicans, Cryptococcus neoformans, Aspergillus fumigatus, Trichophyton spp., Microsporum spp., Exophiala spp., Blastomyces dermatitidis, and Histoplasma capsulatum. Thus, the bicyclic compounds of the present invention are useful for topical and systemic treatment of mycoses in animals as well as in human. Accordingly, the present invention comprises the use of the above compounds for the manufacture of medicaments for the prophylaxis and treatment of mycoses and the corresponding pharmaceutical compositions which comprise a bicyclic compound as defined above and a pharmaceutically acceptable carrier. For example, they are useful in treating topical and mucous Trichophyton, or Microsporum.

The inhibitory activity of the bicyclic compounds of the present invention can be demonstrated as follows: Determination of the NMT inhibitory activity Candida albicans NMT inhibitory activity was measured using the method reported by David A. Rudnick et al. (J. Biol. Chem. Vol.267, PP. 23852-23861, 1992). The inhibitory activity of the compounds of the general formula [I] on Candida NMT ranged from 0.002 μg/ml to 100 μg/ml. Determination of in vitro antifungal activity In vitro antifungal activity of the bicyclic compounds was determined using the Cryptococcus neoformans (Cr. neoformans) cells (strain MTU13001) according to the broth micro-dilution procedure (National Committee for Clinical Laboratory Standard (1992).

Antifungal activity of each compound was indicated as 50% inhibition concentration (IC 50 ) values that was determined by calculation the minimum concentration of the compound required for the 50% reduction of the turbidity (OD600) of cells compared to untreated control cells.

The LD 50 value of the compound obtained in Example 42 as mentioned below was more than 50 mg/Kg. For clinical use, the bicycle compounds of the formula [I] or salt forms thereof and the like can be administered alone, but will generally be administered in pharmaceutical admixture formulated as appropriate to the particular use and purpose desired, by mixing excipient, binding agent, lubricant, disintegrating agent, coating material, emulsifier, suspending agent, solvent, stabilizer, absorption enhancer and /or ointment base. The admixture can be used for oral, injectable, rectal or topical administration. In more detail, as mentioned earlier, medicaments containing a compound of formula [I] are also an object of the present invention, as is a process for the manufacture of such medicaments, which process comprises bringing one or more compounds of formula [I] and, if desired, one or more other therapeutically valuable substances into a galenical administration form. The pharmaceutical compositions may be administered orally, for example in the form of tablets, coated tablets, dragees, hard or soft gelatine capsules, solutions, emulsions or suspensions. Administration can also be carried out rectally, for example using suppositories; locally or percutaneously, for example using ointments, creams, gels or solutions; or parenterally, for example using injectable solutions. For the preparation of tablets, coated tablets, dragees or hard gelatine capsules the compounds of the present invention may be admixed with pharmaceutically inert, inorganic or organic excipients. Examples of suitable excipients for tablets, dragees or hard gelatine capsules include lactose, maize starch or derivatives thereof, talc or stearic acid or salts thereof. Suitable excipients for use with soft gelatine capsules include for example vegetable oils, waxes, fats, semi-solid or liquid polyols etc.; according to the nature of the active ingredients it may however be the case that no excipient is needed at all for soft gelatine capsules. For the preparation of solutions and syrups, excipients which may be used include for example water, polyols, saccharose, invert sugar and glucose. For injectable solutions, excipients which may be used include for example water, alcohols, polyols, glycerine, and vegetable oils. For suppositories, and local or percutaneous application, excipients which may be used include for example natural or hardened oils, waxes, fats and semi-solid or liquid polyols. The pharmaceutical compositions may also contain preserving agents, solubilising agents, stabilising agents, wetting agents, emulsifiers, sweeteners, colorants, odorants, salts for the variation of osmotic pressure, buffers, coating agents or antioxidants. They may also contain other therapeutically valuable agents. In summary, a pharmaceutical formulation for oral administration may be granule, table, sugar coated tablet, capsule, pill, suspension or emulsion, which for parenteral injection, for example, intravenously, intramuscularly or subcutaneously, may be used in the form of a sterile aqueous solution which may contain other substances, for example, salts or glucose to make the solution isotonic. The antifungal can also be administered in the form of a suppository or pessary, or they may be applied topically in the form of a lotion, solution, cream, ointment or dusting powder. The daily dosage level of the antifungal compounds of the formula [I] is from 0.1 to 100 mg/Kg when administered by either the oral or parenteral route. Thus tablets or capsules can contain from 5 mg to 1000 mg of active compound for administration singly or two or more at a time as appropriate. In any event the actual dosage can be weight and response of the particular patient. The bicycle compounds of the formula [I] and salts thereof have activity against a variety of plant pathogenic fungi, including for example Pyricularia oryzae, Pythium aphanidermatum, Alternaria spp., and Paecilomyces variotii. Thus, they can be applied for agricultural and horticultural purposed preferably in the form of a composition formulated as dusting powders, or granules, seed dressings, aqueous solutions, dispersions or emulsions, dips, sprays or aerosols. Such compositions may contain such conventional carriers, diluents or adjuvants as are known and acceptable in agriculture and horticulture. Other compound having herbicidal or insecticidal, or additional antifungal compositions can be applied in a number of ways, for example they can be applied directly to the plant foliage, stems, branches, seeds or roots or to the soil or other growing medium, and they may be used not only to eradicate disease, but also prophylactically to protect the plants or seeds from fungal attack.
