Description

NOVEL BISAMIDATE PHOSPHONATE PRODRUGS Field of the Invention The present invention is directed towards novel prodrugs, to their preparation, to their use for the oral delivery of Fructose-l,6-bisphosphatase inhibitors (FBPase), and to their use in the treatment of diabetes and other diseases where the inhibition of gluconeogenesis, control of blood glucose levels, reduction in glycogen storage, or reduction in insulin levels is beneficial.

Background of the Invention Organic compounds that are charged at physiological pH frequently exhibit limited oral bioavailability, cell penetration, and tissue distribution CNS). These properties are attributed to the failure of ionic compounds to cross cell membranes by passive diffusion.

One strategy to circumvent this problem is to prepare lipophilic prodrugs which are capable of crossing cell membranes and subsequently undergoing a transformation to generate the charged compound. The transformation could result from either chemical instability or an enzyme-catalyzed reaction.

A large number of structurally-diverse prodrugs are described for phosphonic acids.

Freeman and Ross in Progress in Medicinal Chemistry 34: 112-147 (1997). The most commonly used prodrug class is the acyloxyalkyl ester, which was first used as a prodrug strategy for carboxylic acids and then applied to phosphates in 1983 by Farquhar et al. J Pharm. Sci. 72: 324 (1983). Subsequently, the acyloxyalkyl ester was used to deliver phosphonic acids across cell membranes and to enhance oral bioavailability. A close variant of the acyloxyalkyl ester strategy, the alkoxycarbonyloxyalkyl ester, is also reported to enhance oral bioavailability.

Much less success has been achieved with other classes ofphosphonate prodrugs.

Aryl esters, especially phenyl esters, are reported in a few cases to enhance oral bioavailability. DeLambert et al., J. Med. Chem. 37: 498 (1994). Phenyl esters containing a carboxylic ester ortho to the phosphate have also been described. Khamnei and Torrence, J Med. Chem. 39:4109-4115 (1996). Benzyl esters are reported to generate the parent phosphonic acid. In some cases using substituents at the ortho- orpara-position can accelerate the hydrolysis. Benzyl analogs with an acylated phenol or an alkylated phenol can generate the phenolic compound through the action of enzymes, e.g. esterases, oxidases, etc., which in turn undergoes cleavage at the benzylic C-O bond to generate the phosphoric acid and the quinone methide intermediate. Examples of this class of prodrugs are described by Mitchell et al., J Chem. Soc. Perkin Trans. 12345 (1992); Brook, et al. WO 91/19721. Still other benzylic prodrugs have been described containing a carboxylic ester-containing group attached to the benzylic methylene. Glazier et al. WO 91/19721. Thio-containing prodrugs are reported to be useful for the intracellular delivery ofphosphonate drugs. These proesters contain an ethylthio group in which the thiol group is either esterified with an acyl group or combined with another thiol group to form a disulfide. Desterification or reduction of the disulfide generates the free thio intermediate which subsequently breaks down to the phosphoric acid and episulfide. Puech et al., Antiviral Res., 22: 155-174 (1993); Benzaria, et al., J. Med. Chem. 39: 4958 (1996). Cyclic phosphonate esters have also been described as prodrugs of phosphorus-containing compounds.

Some phosphoramidates are also known prodrugs of phosphonates, but they have shown poor oral bioavailability. In some cases the phosphoramidates were very unstable under acidic conditions which was reported as a potential explanation for their poor oral bioavailability (J Med. Chem., 37: 1857-1864 (1994)). Similarly, poor oral bioavailability was reported for a bisamidate of a PMEA analog Med. Chem., 38: 1372-1379 (1995)).

00 Another PMEA prodrug consists of a mono glycine ester amidate and a phenyl ester (WO 95/07920).

SAlthough numerous phosphoric acid prodrug strategies are reported to achieve high intracellular delivery of phosphoric acids, few are known to result in good oral bioavailability. In some cases, the prodrugs are unstable to the gastrointestinal tract environment (low pH, esterase activity). In other cases the prodrugs are too stable and are IsO thereof poorly transformed in vivo to the parent drug.

The groups illustrated are exemplary, not exhaustive, and one skilled in the art could prepare other known varieties of prodrugs. Such prodrugs of the compounds of formulae I, X, and XI, fall within the scope of the present invention.

Prodrugs must undergo some form of a chemical transformation to produce the compound that is biologically active or is a precursor of the biologically active compound. In some cases, the prodrug is biologically active usually less than the drug itself, and serves to improve efficacy or safety through improved oral bioavailability, pharmacodynamic half-life, etc.

Phosphoramidate derivatives have been explored as phosphate prodrugs (e.g.

McGuigan et al., J. Med. Chem., 1999, 42. 393 and references cited therein) and phosphonate prodrugs (Bischofberger, et al., U.S. 5,798,340 and references cited therein) as shown in Formulae G and H.

Section 1.

Synthesis of Compounds of Formula I Synthesis of compounds encompassed by the present invention typically includes some or all of the following general steps: preparation of a phosphonate prodrug; (2) deprotection of a phosphonate ester; modification of a heterocycle; coupling of a heterocycle with a phosphonate component; construction of a heterocycle; ring closure to construct a heterocycle with a phosphonate moiety present and preparation of useful intermediates. These steps are illustrated in the following scheme for compounds of formula I wherein R 5 is a 5-membered heteroaromatic ring. Compounds of formula I wherein R s is a 6member heteroaromatic ring or other heteroaromatic rings are prepared in an analogous manner.

6 and

-N(R

18 2 R 3 )n-C(O)-R 14 are fiom the same amino acid residues, can be prepared from the activated phosphonates for example, dichlorophosphonate, by coupling with an amino acid ester for example, glycine ethylester with or without base for example, N-methylimidazole. The reactive dichloridates, can be prepared from the corresponding phosphonic acid and a chlorinating agent for example, thionyl chloride (Starrett, et al., J Med. Chem., 1994, 1857), oxalyl chloride (Stowell, et al., Tetrahedron Lett., 1990, 31, 3261), or phosphorous pentachloride (Quast, et al., Synthesis, 1974, 490). These dichloridates can also be prepared from their corresponding disilyl esters (Bhongle, et al., Synth. Commun., 1987, 17, 1071) and dialkyl esters (Still, et al., Tetrahedron Lett., 1983, 24, 4405; Patois, et al., Bull. Soc. Chim. Fr., 1993, 130, 485).

Alternatively, these bis-phosphoroamidates can be prepared by reacting the corresponding phosphonic acid with an amino acid ester for example, glycine ethylester in presence ofPPh 3 and 2,2'-dipyridyl disulfide in pyridine as described in WO 95/07920 or Mukaiyama, T. et al, JAm. Chem. Soc., 1972, 94, 8528.

Synthesis of mixed bis-phosphoroamidates of formula I, where -NR 5

R

1 6 and -N(Rls)-(CR2R"3),C(O)-R 14 are different amino acid esters or a combination of an amino acid ester and a substituted amine, can be prepared by direct conversion via dichloridate as described above (sequential addition) followed by purification of the desired product by column chromatography). Alternatively, these unsymmetrical bis-phosphoroamidates can be prepared starting with an appropriate phosphonate monoester such as phenyl ester or benzyl ester to give the mixed phosphonoesteramide via the chloridate, followed by ester hydrolysis under conditions where the amide bond is stable. The resultant mono-amide can be converted to a mixed bisamide by condensation with a second amino ester or a substituted amine via the chloridate, as described above. Synthesis of such monoesters can be prepared using the reported procedure (EP 481 214).

Deprotection of a phosphonate ester Compounds of formula 2 may be prepared from phosphonate esters using known phosphate and phosphonate ester cleavage conditions. Silyl halides are generally used to cleave various phosphonate esters, and subsequent mild hydrolysis of the resulting silyl phosphonate esters give the desired phosphonic acids. When required, acid scavengers (e.g.

1,1,1,3,3,3-hexamethyldisilazane, 2,6-lutidine, etc.) can be used for the synthesis of acid labile compounds. Such silyl halides include chlorotrimethylsilane (Rabinowitz, J. Org.

Chem., 1963, 28: 2975), and bromotrimethylsilane (McKenna, et al, Tetrahedron Lett., 1977, 155), and iodotrimethylsilane (Blackburn, et al, J. Chem. Soc., Chem. Commun., .1978, 870).

Alternately, phosphonate esters can be cleaved under strong acidic conditions HBr or HCI: Moffatt, et al, U.S. Patent 3,524,846, 1970). These esters can also be cleaved via dichlorophosphonates, prepared by treating the esters with halogenating agents (e.g.

phosphorus pentachloride, thionyl chloride, BBr 3 Pelchowicz et al, J Chem. Soc., 1961, 238) followed by aqueous hydrolysis to give phosphonic acids. Aryl and benzyl phosphonate esters can be cleaved under hydrogenolysis conditions (Lejczak, et al, Synthesis, 1982, 412; Elliott, et al, J. Med. Chem., 1985, 28: 1208; Baddiley, et al, Nature, 1953, 171: 76 or metal reduction conditions (Shafer, et al, J. Am. Chem. Soc., 1977, 99: 5118). Electrochemical (Shono, et al, J. Org. Chem., 1979, 44: 4508) and pyrolysis (Gupta, et al, Synth. Commun., 1980, 10: 299) conditions have also been used to cleave various phosphonate esters.

Modification of an existing heterocvcle Syntheses of the heterocycles encompassed in the disclosed compounds have been well studied and described in numerous reviews (see section Although it is advantageous to have the desired substituents present in these heterocycles before synthesis of compounds of formula 4, in some cases, the desired substituents are not compatible with subsequent reactions, and therefore modifications of an existing heterocycle are required late in the synthetic scheme using conventional chemistry (Larock, Comprehensive organic transformations, VCH, New York, 1989; Trost, Comprehensive organic synthesis; Pergamon press, New York, 1991). For example, compounds of formula I wherein A, or B is a halo or a cyano group can be prepared from the corresponding amine group by conversion to the diazonium group and reaction with various copper salts Cul, CuBr, CuC1, CuCN).

Halogens can also be introduced by direct halogenations of various heterocycles. For example, 5-unsubstituted-2-aminothiazoles can be converted to 2-amino-5-halothiazoles using various reagents NIS, NBS, NCS). Heteroaryl halides are also useful intermediates and are often readily converted to other substituents (such as A, B, D, E and E") via transition metal assisted coupling reactions such as Suzuki, Heck or Stille reactions (Farina et al, Organic Reactions, Vol. 50; Wiley, New York, 1997; Mitchell, Synthesis, 1992, 808; Suzuki, Pure App. Chem., 1991, 63, 419; Heck Palladium Reagents in Organic Synthesis; Academic Press: San Diego, 1985). Compounds of formula I wherein A is a carbamoyl group can be made from their corresponding alkyl carboxylate esters via aminolysis with various amines, and conventional functional group modifications of the alkyl carboxylate esters are useful for syntheses of compounds of formula I wherein A is a -CH 2

OH

group or a -CH 2 -halo group. Substitution reactions ofhaloheterocycles 2-bromothiazole, 5-bromothiazole) with various nucleophiles HSMe, HOMe, etc.) represents still another method for introducing substituents such as A, B and For example, substitution of a 2-chlorothiazole with methanethiol gives the corresponding 2-methylthiothiazole.

It is envisioned that when necessary alkylation of nitrogen atoms in the heterocycles imidazoles, 1,2,4-triazoles and 1,2,3,4-tetrazoles) can be readily performed using for example standard alkylation reactions (with an alkyl halide, an aralkyl halide, an alkyl sulfonate or an aralkyl sulfonate), or Mitsunobu reactions (with an alcohol).

Coupling of a heterocycle with a phosphonate component When feasible compounds disclosed in the present invention are prepared via a convergent synthetic route entailing the coupling of a heterocycle with a phosphonate diester component.

Transition metal catalyzed coupling reactions such as Stille or Suzuki reactions are particularly suited for the synthesis of compounds of formula I. Coupling reactions between a heteroaryl halide or triflate 2-bromopyridine) and a M-PO 3 R' wherein M is a O tributylstannyl)furanyl or a 2-(5-boronyl)furanyl group under palladium catalyzed reaction conditions (Farina et al, Organic Reactions, Vol. 50; Wiley, New York, 1997; Mitchell, Synthesis, 1992, 808; Suzuki, Pure App. Chem., 1991, 63, 419) yield compounds of formula I f" wherein X is a furan-2,5-diyl group. It is envisioned that the nature of the coupling partners

O\

S5 for these reactions can also be reversed coupling of trialkylstannyl or boronyl Sheterocycles with a halo-X-P(O)(O-alkyl) 2 Other coupling reactions between organostannes DO and an alkenyl halide or an alkenyl triflate are also reported which may be used to prepared 0 compounds of formula I wherein X is an alkenyl group. The Heck reaction may be used to prepare compounds of formula I wherein X is an alkenyl group (Heck Palladium Reagents in Organic Synthesis; Academic Press: San Diego, 1985). These reactions are particularly suited for syntheses of various heteroaromatics as K 5 for compounds of formula I given the availability of numerous halogenated heterocycles, and these reactions are particularly suitable for parallel synthesis combinatorial synthesis on solid phase (Bunin, B. The Combinatorial Index; Academic Press: San Diego, 1998) or in solution phase (Flynn, D. L. et al., Curr. Op. Drug. Disc. Dev., 1998, 1, 1367)) to generate large combinatorial libraries. For example, ethyl 5-iodo-2-furanylphosphonate can be coupled to Wang's resin under suitable coupling reaction conditions. The resin-coupled 5-iodo-2-[5-(O-ethyl-O-Wang's resin)phosphono]furan can then be subjected to transition metal catalyzed Suzuki and Stille reactions (as described above) with organoboranes and organotins in a parallel manner to give libraries of compounds of formula 3 wherein X is Substitution reactions are useful for the coupling of a heterocycle with a phosphonate diester component. For example, cyanuric chloride can be substituted with dialkyl mercaptoalkylphosphonates or dialkyl aminoalkylphosphonates to give compounds of formula I wherein R 5 is a 1,3,5-triazine, X is an alkylthio or an alkylamino group. Alkylation reactions are also used for the coupling of a heterocycle with a phosphonate diester component. For example, a heteroaromatic thiol a 1,3,4-thiadiazole-2-thiol) can be alkylated with a dialkyl methylphosphonate derivative ICH 2 P(O)(OEt) 2 TsOCH 2 P(O)(OEt) 2 TfOCH 2 P(O)(OEt) 2 to lead to compounds of formula I wherein X is an alkylthio group. In another aspect, alkylation reactions of a heteroaromatic carboxylic acid a thiazole-4-carboxylic acid) with a dialkyl methylphosphonate derivative (e.g.

ICH

2 P(O)(OEt) 2 TsOCH 2 P(O)(OEt) 2 TfOCH 2 P(O)(OEt) 2 lead to compounds of formula I wherein X is an alkoxycarbonyl group, while alkylation reactions of a heteroaromatic thiocarboxylic acid a thiazole-4-thiocarboxylic acid) with a dialkyl methylphosphonate derivative ICH 2 P(O)(OEt) 2 TsOCH 2 P(O)(OEt) 2 TfOCH 2 P(O)(OEt) 2 lead to INDcompounds of formula I wherein X is an alkylthiocarbonyl group. Substitutions of haloalkyl heterocycles 4-haloallcylthiazole) with nucleophiles containing the phosphonate group (diethyl hydroxymethylphosphonate) are useful for the preparation of compounds of formula I wherein X is an allcoxyalkyl or an allylthioalkyl group. For example, compounds of formula I where X is a -CH20CH 2 group can be prepared from 2-chloromethylpyridine or 4chloromethylthiazole using diallcyl hydroxymethylphosphonates and a suitable base (e.g.

sodium hydride). It is possible to reverse the nature of the nucleophiles and electrophiles for the substitution reactions, i.e. haloallcyl- and/or sulfonylalkylphosphonate esters can be substituted with heterocycles containing a nucleophile a 2-hydroxyalcylpyridine, a 2mercaptoalkylpyridine, or a 4-hydroxyalkyloxazole).

Known amide bond formation reactions the acyl halide method, the mixed anhydride method, the carbodiimide method) can also be used to couple a heteroaromatic carboxylic acid with a phosphonate diester component leading to compounds of formula I wherein X is an alkylaminocarbonyl or an alkloxycarbonyl group. For example, couplings of a thiazole-4-carboxylic acid with a dialkyl aminoakylphosphonate or a dialkyl hydroxyallcylphosphonate give compounds of formula I wherein R 5 is a thiazole, and X is an alkylaminocarbonyl or an alkoxycarbonyl group. Alternatively, the nature of the coupling partners can be reversed to give compounds of formula I wherein X is an alkylcarbonylamino group. For example, 2-aminothiazoles can be coupled with (RO) 2 P(O)-alkyl-COH (e.g.

diethylphosphonoacetic acid) under these reaction conditions to give compounds of formula I wherein R 5 is a thiazole and X is an alkylcarbonylamino group. These reactions are also useful for parallel synthesis of compound libraries through combinatorial chemistry on solid phase or in solution phase. For example, HOCH 2 P(O)(OEt)(O-resin), H 2

NCH

2 P(O)(OEt)(Oresin) and HOOCCH 2 P(O)(OEt)(O-resin) (prepared using known methods) can be coupled to various heterocycles using the above described reactions to give libraries of compounds of formula 3 wherein X is a -C(O)OCH 2 or a -C(O)NHCH 2 or a NHC(O)CH 2 Rearrangement reactions can also be used to prepare compounds covered in the present invention. For example, the Curtius' rearrangement of a thiazole-4-carboxylic acid in the presence of a dialkyl hydroxyalkylphosphonate or a dialkyl aminoalkylphosphonate lead to compounds of formula I wherein X is an alkylaminocarbonylamino or an alkoxycarbonylamino group. These reactions can also be adopted for combinatorial synthesis of various libraries of compounds of formula 3. For example, Curtius' rearrangement reactions between a heterocyclic carboxylic acid and HOCH 2 P(O)(OEt)(O-resin), or H2NCH2P(O)(OEt)(O-resin) can lead to libraries of compounds of formula I wherein X is a

NHC(O)OCH

2 or a NHC(O)NHCH 2 For compounds of formula I wherein X is an alkyl group, the phosphonate group can be introduced using other common phosphonate formation methods such as Michaelis- Arbuzov reaction (Bhattacharya et al., Chem. Rev., 1981, 81: 415), Michaelis-Becker reaction (Blackburn et al., J. Organomet. Chem., 1988, 348: 55), and addition reactions of phosphorus to electrophiles (such as aldehydes, ketones, acyl halides, imines and other carbonyl derivatives).

Phosphonate component can also be introduced via lithiation reactions. For example, lithiation of an 2-ethynylpyridine using a suitable base followed by trapping the thus generated anion with a dialkyl chlorophosphonate lead to compounds of formula I wherein R is a pyridyl, X is a 1-(2-phosphono)ethynyl group.

Construction of a heterocvcle Although existing heterocycles are useful for the synthesis of compounds of formula I, when required, heterocycles can also be constructed leading to compounds in the current invention. The construction of heterocycles have been well described in the literature using a variety of reaction conditions (Joule et al., Heterocyclic Chemistry; Chapman hall, London, 1995; Boger, Weinreb, Hetero Diels-Alder Methodology In Organic Synthesis; Academic press, San Diego, 1987; Padwa, 1,3-Dipolar Cycloaddition Chemistry; Wiley, New York, 1984; Katritzsky et al., Comprehensive Heterocyclic Chemistry. Pergamon press, Oxford; Newkome et al., Contemporary Heterocyclic Chemistry: Syntheses, Reaction and Applications; Wiley, New York, 1982; Syntheses ofHeterocyclic Compounds; Consultants Bureau, New York). Some of the methods which are useful to prepare compounds in the present invention are given as examples in the following discussion.

Construction of a thiazole ring system Thiazoles useful for the present invention can be readily prepared using a variety of well described ring-forming reactions (Metzger, Thiazole and its derivatives, part 1 and part 2; Wiley Sons, New York, 1979). Cyclization reactions of thioamides thioacetamide, thiourea) and alpha-halocarbonyl compounds (such as alpha-haloketones, alphahaloaldehydes) are particularly useful for the construction of a thiazole ring system. For example, cyclization reactions between thiourea and 5-diethylphosphono-2-[(-2-bromo-loxo)alkyl]furans are useful for the synthesis of compounds of formula I wherein R 5 is a thiazole, A is an amino group and X is a furan-2,5-diyl group; cyclization reaction between thiourea and a bromopyruvate alkyl ester give a 2-amino-4-alkoxycarbonylthiazole which is useful for the preparations of compounds of formula I wherein R s is a thiazole and X is an alkylaminocarbonyl, an alkoxycarbonyl, an alkylaminocarbonylamino, or an alkoxyacarbonylamino group. Thioamides can be prepared using reactions reported in the literature (Trost, Comprehensive organic synthesis, Vol. 6; Pergamon press, New York, 1991, pages 419 434) and alpha-halocarbonyl compounds are readily accessible via conventional reactions (Larock, Comprehensive organic transformations, VCH, New York, 1989). For example, amides can be converted to thioamides using Lawesson's reagent or P 2 S5, and ketones can be halogenated using various halogenating reagents NBS, CuBr 2 (ii) Construction of an oxazole ring system Oxazoles useful for the present invention can be prepared using various methods in the literature (Turchi, Oxazoles; Wiley Sons, New York, 1986). Reactions between isocyanides tosylmethylisocyanide) and carbonyl compounds aldehydes and acyl chlorides) can be used to construct oxazole ring systems (van Leusen et al, Tetrahedron Lett., 1972, 2369). Alternatively, cyclization reactions of amides urea, carboxamides) and alpha-halocarbonyl compounds are commonly used for the construction of an oxazole ring system. For example, the reactions of urea and 5-diethylphosphono-2-[(-2-bromo-loxo)alkyl]furans are useful for the synthesis of compounds of formula I wherein R 5 is an oxazole, A is an amino group and X is a furan-2,5-diyl group. Reactions between amines and imidates are also used to construct the oxazole ring system (Meyers et al, J. Org. Chem., 1986, 51(26), 5111).

(iii) Construction of a pyridine ring system Pyridines useful for the synthesis of compounds of formula I can be prepared using various known synthetic methods (Klingsberg, Pyridine and Its Derivatives; Interscience Publishers, New York, 1960 -1984). 1,5-Dicarbonyl compounds or their equivalents can be reacted with ammonia or compounds which can generate ammonia to produce 1,4dihydropyridines which are easily dehydrogenated to pyridines. When unsaturated dicarbonyl compounds, or their equivalents pyrylium ions) are used to react with ammonia, pyridines can be generated directly. 1,5-Dicarbonyl compounds or their equivalents can be prepared using conventional chemistry. For example, 1,5-diketones are accessible via a number of routes, such as Michael addition of an enolate to an enone (or precursor Mannich base (Gill et al, J. Am. Chem. Soc., 1952, 74, 4923)), ozonolysis of a cyclopentene precursor, or reaction of silyl enol ethers with 3-methoxyallylic alcohols (Duhamel et al, Tetrahedron, 1986, 42, 4777). When one of the carbonyl carbons is at the acid oxidation state, then this type of reaction produces 2-pyridones which can be readily converted to 2-halopyridines (Isler et al, Helv. Chim. Acta, 1955, 38, 1033) or 2aminopyridines (Vorbruggen etal, Chem. Ber., 1984, 117, 1523). Alternatively, a pyridine can be prepared from an aldehyde, a 1,3-dicarbonyl compound and ammonia via the classical Hantzsch synthesis (Bossart et al, Angew. Chem. Int. Ed. Engl.,1981, 20, 762). Reactions of 1,3-dicarbonyl compounds (or their equivalents) with 3-amino-enones or 3-amino-nitriles have also been used to produce pyridines (such as the Guareschi synthesis, Mariella, Org.

Synth., Coll, Vol. IV, 1963, 210). 1,3-Dicarbonyl compounds can be made via oxidation reactions on corresponding 1,3-diols or aldol reaction products (Mukaiyama, Org, Reactions, 1982, 28, 203). Cycloaddition reactions have also been used for the synthesis of pyridines, for example cycloaddition reactions between oxazoles and alkenes (Naito et al., Chem.

Pharm. Bull., 1965, 13, 869), and Diels-Alder reactions between 1,2,4-triazines and enamines (Boger et al., J. Org. Chem., 1981, 46, 2179).

(iv) Construction of a pvrimidine ring system Pyrimidine ring systems useful for the synthesis of compounds of formula I are readily available (Brown, The pyrimidines; Wiley, New York, 1994). One method for pyrimidine synthesis involves the coupling of a 1,3-dicarbonyl component (or its equivalent) with an N- C-N fragment. The selection of the N-C-N component urea (Sherman et al., Org. Synth., Coll. Vol. IV, 1963, 247), amidine (Kenner et al., J Chem. Soc., 1943, 125) or guanidine (Burgess, J Org. Chem., 1956, 21, 97; VanAllan, Org. Synth., Coll. Vol. IV, 1963, 245) governs the substitution at C-2 in the pyrimidine products. This method is particular useful for the synthesis of compounds of formula I with various A groups. In another method, pyrimidines can be prepared via cycloaddition reactions such as aza-Diels-Alder reactions between a 1,3,5-triazine and an enamine or an ynamine (Boger et al., J. Org. Chem., 1992, 57, 4331 and references cited therein).

Construction of an imidazole ring system Imidazoles useful for the synthesis of compounds of formula I are readily prepared using a variety of different synthetic methodologies. Various cyclization reactions are generally used to synthesize imidazoles such as reactions between amidines and alphahaloketones (Mallick et al, J Am. Chem. Soc., 1984, 106(23), 7252) or alpha-hydroxyketones (Shi et al, Synthetic Comm., 1993, 23(18), 2623), reactions between urea and alphahaloketones, and reactions between aldehydes and 1,2-dicarbonyl compounds in the presence of amines.

(vi) Construction of an isoxazole ring system Isoxazoles useful for the synthesis of compounds of formula I are readily synthesized using various methodologies (such as cycloaddition reactions between nitrile oxides and alkynes or active methylene compounds, oximation of 1,3-dicarbonyl compounds or alpha, beta-acetylenic carbonyl compounds or alpha,beta-dihalocarbonyl compounds, etc.) can be used to synthesize an isoxazole ring system (Grunanger et al., Isoxazoles; Wiley Sons, New York, 1991). For example, reactions between alkynes and 5-diethylphosphono-2chlorooximidofuran in the presence of base triethylamine, Hunig's base, pyridine) are useful for the synthesis of compounds of formula I wherein R 5 is an isoxazole and X is a group.

(vii) Construction of a pvrazole ring system Pyrazoles useful for the synthesis of compounds of formula I are readily prepared using a variety of methods (Wiley, Pyrazoles, Pyrazolines, Pyrazolidines, Indazoles, and Condensed Rings; Interscience Publishers, New York, 1967) such as reactions between hydrazines and 1,3-dicarbonyl compounds or 1,3-dicarbonyl equivalents one of the carbonyl group is masked as an enamine or ketal or acetal), and additions of hydrazines to acrylonitriles followed by cyclization reactions (Dom et al, Org. Synth., 1973, Coll. Vol. V, 39). Reaction of 2-(2-alkyl-3-N,N-dimethylamino)acryloyl-5-diethylphosphonofurans with hydrazines are useful for the synthesis of compounds of formula I wherein R 5 is a pyrazole, X is a furan-2,5-diyl group and B" is an alkyl group.

(viii) Construction of a 1,2,4-triazole ring system 1,2,4-Triazoles useful for the synthesis of compounds of formula I are readily available via various methodologies (Montgomery, 1,2,4-Triazoles; Wiley, New York, 1981).

For example, reactions between hydrazides and imidates or thioimidates (Sui et al., Bioorg.

Med. Chem. Lett., 1998, 8, 1929; Catarzi et J Med. Chemn., 1995, 38(2), 2196), reactions r~l between 1,3,5-triazine and liydrazines (Grundmann et al., J Org. Chem., 1956, 21, 1037), and reactions between aminoguanidine and carboxylic esters (Ried et al., Chemn. Ber., 1968, 101, 2117) are used to synthesize 1,2,4-triazoles.

Ring closure to construct a heterocycle with a phosphonate Compounds of formula 4 can also be prepared using a ring closure reaction to construct the heterocycle from precursors that contain the phosphonate component. For ~K1 example, cyclization reactions between thiourea and 5-diethylphosphono-2-[(-2-bromo-loxo)alkyl]furans are useful for the synthesis of compounds of formula I wherein R5 is a thiazole, A is an amrino group and X is a furan-2,5-diyl group. Oxazoles of the present invention can also be prepared using a ring closure reaction. In this case, reactions of urea and 5-diethylphosphono-2-[(-2-bromo--oxo)alkyl]furans are useful for the synthesis of compounds of formula I wherein R 5 is an oxazole, A is an amino group and X is a diyl group. Reactions between 5-diethylphosphono-2-furaldehyde, an alkyl amine, a 1,2diketone and ammonium acetate are useful to synthesize compounds of formula I wherein R is an imidazole and X is a fiaran-2,5-diyl group. These types of ring closure reactions can also be used for the synthesis of pyridines or pyrim-idines useful in the present invention. For example, reaction of 5-diethylphosphono-2-[3-dimethylam-ino-2-alkyl)acryloyl] furans and cyanoacetamide in the presence of base gives 5-alkyl-3-cyano-6-[2-(5diethylphosphono)fiiranyl]-2-pyridones (Jain et al., Tetrahedron Lett., 1995, 36, 3307).

Subsequent conversion of these 2-pyridones to the corresponding 2-halopyridines (see references cited in section 3 for the modifications of heterocycles) will lead to compounds of formula I wherein R 5 is a pyridine, A is a halo group, X is a furan-2,5-diyl group, and B is an alkyl group. Reactions of 5-diethylphosphono-2-[3-dimethylamino-2-alkyl)acryloyl]furans and amidines in the presence of base give 5-alkyl-6-[2-(5-diethylphosphono)furanyl]pyrimidines which will lead to compounds of formula I wherein R' is a pyrimidine, X is a faran-2,5-diyl group and B is an ailkyl group.

Preparation of various precursors useful for cyclization reactions Intermediates required for the synthesis of compounds in the present invention are generally prepared using either an existing method in the literature or a modification of an existing method. Syntheses of some of the intermediates useful for the synthesis of compounds in the present invention are described herein.

Various aryl phosphonate dialkyl esters are particularly useful for the synthesis of compounds of formula I. For example, compounds of formula I wherein X is a group can be prepared fiom a variety of furanyl precursors. It is envisioned that synthesis of other precursors may follow some or all of these reaction steps, and some modifications of these reactions may be required for different precursors. 5-Dialkylphosphono-2furancarbonyl compounds 5-diethylphosphono-2-furaldehyde, 5-diethylphosphono-2acetylfuran) are well suited for the synthesis of compounds of formula I wherein X is a furangroup. These intermediates are prepared from furan or furan derivatives using conventional chemistry such as lithiation reactions, protection ofcarbonyl groups and deprotection of carbonyl groups. For example, lithiation of furan using known methods (Gschwend Org. React., 1979, 26: 1) followed by addition of phosphorylating agents (e.g.

CLPO

3

R

2 gives 2-dialkylphosphono-furans 2-diethylphosphonofuran). This method can also be applied to a 2-substituted furan 2-furoic acid) to give a 5-dialkylphosphono-2substituted furan 5-diethylphosphono-2-furoic acid). It is envisioned that other aryl phosphonate esters can also be prepared using this approach or a modification of this approach. Alternatively, other methods such as transition metal catalyzed reactions of aryl halides or triflates (Balthazar et al. J Org. Chem., 1980, 45: 5425; Petrakis et al. J. Am.

Chem. Soc., 1987, 109:2831; Lu et al. Synthesis, 1987, 726) are used to prepare aryl phosphonates. Aryl phosphonate esters can also be prepared from aryl phosphates under anionic rearrangement conditions (Melvin, Tetrahedron Lett., 1981, 22: 3375; Casteel et al.

Synthesis, 1991, 691). N-Alkoxy aryl salts with alkali metal derivatives of dialkyl phosphonate provide another general synthesis for heteroaryl-2-phosphonate esters (Redmore J. Org. Chem., 1970, 35: 4114).

A second lithiation step can be used to incorporate a second group on the aryl phosphonate dialkyl ester such as an aldehyde group, a trialkylstannyl or a halo group, although other methods known to generate these functionalities aldehydes) can be envisioned as well Vilsmeier-Hack reaction or Reimar-Teimann reaction for aldehyde synthesis). In the second lithiation step, the lithiated aromatic ring is treated with reagents that either directly generate the desired functional group for an aldehyde using DMF,

HCO

2 R, etc.) or with reagents that lead to a group that is subsequently transformed into the desired functional group using lknown chemistry alcohols, esters, nitriles, alkenes can be transformed into aldehydes). For example, lithiation of a 2-dialkylphosphonofuran 2diethylphosphonofuran) under normal conditions LDA in THF) followed by trapping of the thus generated anion with an electrophile tributyltin chloride or iodine) produces a functionalized-2-dialkylphosphonofuran 5-tributylstannyl-2-diethylphosphonofuran or iodo-2-diethylphosphonofuran). It is also envisioned that the sequence of these reactions can be reversed, i.e. the aldehyde moiety can be incorporated first followed by the phosphorylation reaction. The order of the reaction will be dependent on reaction conditions and protecting groups. Prior to the phosphorylation, it is also envisioned that some of these functional groups may be protected using a number of well-known methods protection of aldehydes as acetals, aminals; protection ofketones as ketals). The protected functional group is then unmasked after phosphorylation. (Protective groups in Organic Synthesis, Greene, T.

1991, Wiley, New York). For example, protection of 2-furaldehyde as 1,3-propanediol acetal followed by a lithiation step (using for example LDA) and trapping the anion with a dialkyl chlorophosphate diethyl chlorophosphate), and subsequent deprotection of the acetal functionality under normal deprotection conditions produces the 5-dialkylphosphono-2furaldehyde 5-diethylphosphono-2-furaldehyde). Another example is the preparation of 5-keto-2-dialkylphosphonofurans which encompass the following steps: acylations of furan under Friedel-Crafts reaction conditions give 2-ketofuran, subsequent protection of the ketone as ketals 1,3-propanediol cyclic ketal) followed by a lithiation step as described above gives the 5-dialkylphosphono-2-furanketone with the ketone being protected as a 1,3propanediol cyclic ketal, and final deprotection of the ketal under, for example, acidic conditions gives 2-keto-5-dialkylphosphonofurans Alternatively, 2-ketofurans can be synthesized via a palladium catalyzed reaction between 2- Strialkylstannylfurans 2-tributylstannylfuran) and an acyl chloride acetyl chloride, I 5 isobutyryl chloride). The phosphonate moiety may be present in the 2-trialkylstannylfurans O(e.g. 2-tributylstannyl-5-diethylphosphonofuran). 2-Keto-5-dialkylphosphonofurans can also LO be prepared from a 5-dialkylphosphono-2-furoic acid 5-diethylphosphono-2-furoic acid) Sby conversion of the acid to the corresponding acyl chloride and followed by additions of a Grignard reagent.

Some of the above described intermediates can also be used for the synthesis of other useful intermediates. For example, a 2-keto-5-dialkylphosphonofuran can be further converted to a 1,3-dicarbonyl derivative which is useful for the preparation ofpyrazoles, pyridines or pyrimidines. Reaction of a 2-keto-5-dialkylphosphonofuran diethylphosphonofuran) with a dialkylformamide dialkyl acetal dimethylformamide dimethyl acetal) gives a 1,3-dicarbonyl equivalent as a 2-(3-dialkylamino-2-alkyl-acryloyl)-5dialkylphosphonofuran 2-(3-dimethylaminoacryloyl)-5-diethylphosphonofuran).

It is envisioned that the above described methods for the synthesis of furan derivatives can be, either directly or with some modifications, applied to syntheses of various other useful intermediates such as aryl phosphonate esters thienyl phosphonate esters, phenyl phosphonate esters or pyridyl phosphonate esters).

It is conceivable that when applicable the above described synthetic methods can be adopted for parallel synthesis either on solid phase or in solution to provide rapid SAR (structure activity relationship) exploration of FBPase inhibitors encompassed in the current invention, provided method development for these reactions are successful.

Two of these methods are given as examples as discussed below. One method is the modification of commercially available benzothiazole derivatives to give the appropriate functionality on the benzothiazole ring.

Another method is the annulation of various anilines compounds of formula 4) to construct the thiazole portion of the benzothiazole ring. For example, compounds of formula 3 wherein G" S, A 2

2 0, and R'=Et can be prepared from the commercially available 4-methoxy-2-amino thiazole via a two-step sequence: conversion 4methoxy-2-aminobenzothiazole to 4-hydroxy-2-aminobenzothiazole with reagents such as BBr 3 (Node, et al. J. Org. Chem. 45, 2243-2246, 1980) or AIC13 in presence of a thiol EtSH) (McOmie, J. F. et al. Org. Synth., Collect. Vol. V, 412, 1973) followed alkylation of the phenol group with diethylphosphonomethyl trifluoromethylsulfonate (Phillion, D. et al. Tetrahedron Lett. 27, 1477-1484, 1986) in presence of a suitable base NaH) in polar aprotic solvents DMF) provide the required compound.

Several methods can be used.to convert various anilines to benzothiazoles (Sprague, J.

Land, A. H. Heterocycle. Compd. 5, 506-13, 1957). For example, 2-aminobenzothiazoles (formula 3 wherein A=NH2) can be prepared by annulation of compounds of formula 4 wherein W 2 using various common methods. One method involves the treatment of a suitably substituted aniline with a mixture of KSCN and CuSO 4 in methanol to give a substituted 2-aminobenzothiazole (Ismail, I. Sharp, D. E; Chedekel, M. R. J. Org. Chem.

2243-2246, 1980). Alternatively, a 2-aminobenzothiazole can also be prepared by the treatment of Br 2 in presence of KSCN in acetic acid (Patil, D. Chedekel, M. R. J Org.

Chem. 49, 997-1000, 1984). This reaction can also be done in two step sequence. For example treatment of substituted phenylthioureas with Br 2 in CHC13 gives substituted 2aminobenzothiazoles (Patil, D. Chedekel, M. R. J. Org. Chem. 49, 997-1000, 1984). 2- Aminobenzothiazoles can also be made by condensation of ortho iodo anilines with thiourea in presence of Ni catalyst (NiC1 2 (PPh 3 2 (Takagi, K. Chem. Lett. 265-266, 1986).

Benzothiazoles can undergo electrophilic aromatic substitution to give 6-substituted benzothiazoles (Sprague, J. Land, A. H. Heterocycle. Compd. 5, 606-13, 1957). For example bromination of formula 3 wherein A 2

Furthermore, compounds of formula 3 wherein A is a halo, H, alkoxy, alkylthio or an alkyl can be prepared from the corresponding amino compound (Larock, Comprehensive organic transformations, VCH, New York, 1989; Trost, Comprehensive organic synthesis; Pergamon press, New York, 1991).

(ii) Benzoxazoles Compounds of formula 3 wherein i.e. benzoxazoles, can be prepared by the annulation of ortho aminophenols with suitable reagent cyanogen halide (A=NH 2 Alt, K. et al Heterocyclic Chem. 12, 775, 1975) or acetic acid (A=CH 3 Saa, J. J. Org.

Chem. 57, 589-594, 1992) or trialkyl orthoformate Org. Prep. Proced. Int., 22, 613, 1990)).

Introduction of a Phosphonate Component Compounds of formula 4 (wherein X 2 =CH20 and R'=alkyl) can made in different ways using alkylation and nucleophilic substitution reactions). Typically, compounds of formula 5 wherein M'=OH is treated with a suitable base NaH) in polar aprotic solvent DMF, DMSO) and the resulting phenoxide anion can be alkylated with a suitable electrophile often with a phosphonate component present diethyl iodomethylphosphonate, diethyl trifluoromethylsulphonomethyl phosphonate, diethyl pmethyltoluenesulphonomethylphosphonate). The alkylation method can also be applied to the precursor compounds to compounds of formula 5 wherein a phenol moiety is present and it can be alkylated with a phosphonate containing component. Alternately, compounds of formula 4 can also be made from the nucleophilic substitution of the precursor compounds to compounds of formula 5, for example, wherein a halo group, such as a fluoro or a chloro, is present ortho to a nitro group. For example, a compound of formula 4 (wherein X2=CH 2 0 and R'=Et) can be prepared from a 2-chloro-l-nitrobenzene derivative by treatment with NaOCH 2 P(O)(OEt) 2 in DMF. Similarly, compounds of formula 4 where X 2 -alkyl-S- or -alkyl-N- can also be made.

Synthesis of an aniline derivative Numerous synthetic methods have been reported for the synthesis of aniline derivatives, these methods can be applied to the synthesis of useful intermediates which can lead to compounds of formula X. For example, various alkenyl or aryl groups can be introduced on to a benzene ring via transition metal catalyzed reactions (Kasibhatla, S. et al. WO 98/39343 and the references cited in); anilines can be prepared from their corresponding nitro derivatives via reduction reactions hydrogenation reactions in presence of 10 Pd/C, or reduction reactions using SnC12 in HC1 (Patil, D. Chedekel, M.

R.J. Org. Chem. 49, 997-1000, 1984)).

Section 3.

This suspension may be formulated according to the known art using those suitable dispersing or wetting agents and suspending agents which have been mentioned above. The sterile injectable preparation may also be a sterile injectable solution or suspension in a non-toxic parenterally acceptable diluent or solvent, such as a solution in 1,3-butane-diol or prepared as a lyophilized powder. Among the acceptable vehicles and solvents that may be employed are water, Ringer's solution and isotonic sodium chloride solution. In addition, sterile fixed oils may conventionally be employed as a solvent or suspending medium. For this purpose any bland fixed oil may be employed including synthetic mono- or diglycerides. In addition, fatty acids such as oleic acid may likewise be used in the preparation of injectables.

The amount of active ingredient that may be combined with the carrier material to produce a single dosage form will vary depending upon the host treated and the particular mode of administration. For example, a time-release formulation intended for oral administration to humans may contain approximately 1 to 1000 mg of active material compounded with an appropriate and convenient amount of carrier material which may vary from about 5 to about 95% of the total compositions. The pharmaceutical composition can be prepared to provide easily measurable amounts for administration. For example, an aqueous solution intended for intravenous infusion should contain from about 3 to 330 Pg of the active ingredient per milliliter of solution in order that infusion of a suitable volume at a rate of about 30 mL/hr can occur.

Injection solutions and suspensions may be prepared from sterile powders, granules and tablets of the kind previously described.

Suitable unit dosage formulations include those containing a daily dose or unit, daily sub-dose, or an appropriate fraction thereof, of a fructose 1,6-bisphosphatase inhibitor compound.

It will be understood, however, that the specific dose level for any particular patient will depend on a variety of factors including the activity of the specific compound employed; the age, body weight, general health, sex and diet of the individual being treated; the time and route of administration; the rate of excretion; other drugs which have previously been administered; and the severity of the particular disease undergoing therapy, as is well understood by those skilled in the art.

Utility One aspect of the invention is directed to novel bis-phosphoramidate prodrugs of FBPase inhibitors to increase the oral bioavailability of the parent drugs.

FBPase inhibitors and their prodrugs may be used to treat diabetes mellitus, lower blood glucose levels, and inhibit gluconeogenesis.

FBPase inhibitors and their prodrugs may also be used to treat excess glycogen storage diseases. Excessive hepatic glycogen stores are found in patients with some glycogen storage

IO

diseases. Since the indirect pathway contributes significantly to glycogen synthesis (Shulman, G.I. Phys. Rev._72:1019-1035, 1992), inhibition of the indirect pathway (gluconeogenesis flux) decreases glycogen overproduction.

FBPase inhibitors and their prodrugs may also be used to treat or prevent diseases associated with increased insulin levels. Increased insulin levels are associated with an Sincreased risk of cardiovascular complications and atherosclerosis (Folsom, et al., Stroke, 25:66-73, 1994; Howard, G. et al., Circulation, 93:1809-1817, 1996). FBPase inhibitors and Stheir prodrugs are expected to decrease postprandial glucose levels by enhancing hepatic glucose uptake. This effect is postulated to occur in individuals that are non-diabetic (or prediabetic, i.e. without elevated hepatic glucose output "hereinafter HGO" or fasting blood glucose levels). Increased hepatic glucose uptake will decrease insulin secretion and thereby decrease the risk of diseases or complications that arise from elevated insulin levels.

These aspects are described in greater detail below.

Example A: Inhibition of Human Liver FBPase E. coli strain BL21 transformed with a human liver FBPase-encoding plasmid was obtained from Dr. M. R. El-Maghrabi at the State University of New York at Stony Brook.

The enzyme was typically purified from 10 liters of recombinant E. coli culture as described Gidh-Jain et al. ,1994, The Journal of Biological Chemistry 269, pp 27732-27738).

Enzymatic activity was measured spectrophotometrically in reactions that coupled the formation of product (fructose 6-phosphate) to the reduction of dimethylthiazoldiphenyltetrazolium bromide (MTT) via NADP and phenazine methosulfate (PMS), using phosphoglucose isomerase and glucose 6-phosphate dehydrogenase as the coupling enzymes. Reaction mixtures (200 pl) were made up in 96-well microtitre plates, and consisted of 50 mM Tris-HC1, pH 7.4, 100 mM KC1, 5 mM EGTA, 2 mM MgC1 2 0.2 mM NADP, 1 mg/ml BSA, 1 mM MTT, 0.6 mM PMS, 1 unit/ml phosphoglucose isomerase, 2 units/ml glucose 6-phosphate dehydrogenase, and 0.150 mM substrate (fructose 1,6bisphosphate). Inhibitor concentrations were varied from 0.01 uM to 10 pM. Reactions were started by the addition of 0.002 units of pure hlFBPase, and were monitored for 7 minutes at 590 nm in a Molecular Devices Plate Reader (37 0

The reaction mixtures consist of 25 mM 3H-AMP (54 mCi/mmole) and 0- 5 1000 mM test compound in 25 mM Tris-HCI, pH 7.4, 100 mM KCI and 1 mM MgC12.

fC- 1.45 mg of homogeneous FBPase nmole) is added last. After a 1 minute incubation, AMP Sbound to FBPase is separated from unbound AMP by means of a centrifugal ultrafiltration Sunit ("Ultrafree-MC", Millipore) used according to the instructions of the manufacturer. The radioactivity in aliquots (100 l) of the upper compartment of the unit (the retentate, which contains enzyme and label) and the lower compartment (the filtrate, which contains unbound label) is quantified using a Beckman liquid scintillation counter. The amount of AMP bound to the enzyme is estimated by comparing the counts in the filtrate (the unbound label) to the total counts in the retentate.

Example C: Inhibition of Gluconeogenesis in Rat Hepatocytes Hepatocytes were prepared from overnight fasted Sprague-Dawley rats (250-300 g) according to the procedure of Berry and Friend (Berry, Friend, 1969, J. Cell. Biol.

43, 506-520) as modified by Groen (Groen, Sips, Vervoom, Tager, J.M., 1982, Eur. J. BioChem. 122, 87-93). Hepatocytes (75 mg wet weight/ml) were incubated in I ml Krebs-bicarbonate buffer containing 10 mM Lactate, 1 mM pyruvate, 1 mg/ml BSA, and test compound concentrations from 1 to 500 pM. Incubations were carried out in a oxygen, 5% carbon dioxide atmosphere in closed, 50-mi Falcon tubes submerged in a rapidly shaking water bath (37 After 1 hour, an aliquot (0.25 ml) was removed, transferred to an Eppendorf tube and centrifuged. 50 pl of supernatant was then assayed for glucose content using a Sigma Glucose Oxidase kit as per the manufacturer's instructions.

ICso's for select compounds in this assay are shown in the table below.

Isolated rat hepatocytes are prepared as described in Example C and incubated under the identical conditions described. Reactions are terminated by removing an aliquot (250 uL) of cell suspension and spinning it through a layer of oil (0.8 ml silicone/mineral oil, 4/1) into a perchloric acid layer (100 uL). After removal of the oil layer, the acidic cell extract layer is neutralized by addition of 1/3rd volume of3 M KOH/3 M KHCO3. After thorough mixing and centrifugation, the supernatant is analyzed for glucose content as described in Example C, and also for fructose-l,6-bisphosphate. Fructose 1,6-bisphosphate is assayed spectrophotometrically by coupling its enzymatic conversion to glycerol 3-phosphate to the oxidation of NADH, which is monitored at 340 nm. Reaction mixtures (1 mL) consist of 200 mM Tris-HC1, pH 7.4, 0.3 mM NADH, 2 units/ml glycerol 3-phosphate dehydrogenase, 2 units/ml triosephosphate isomerase, and 50-100 ul cell extract. After a 30 minute preincubation at 37 0 C, 1 unit/ml of aldolase is added and the change in absorbance measured until a stable value is obtained. 2 moles of NADH are oxidized in this reaction per mole of fructose-1,6-bisphosphate present in the cell extract.

A dose-dependent inhibition of glucose production accompanied by a dose-dependent Saccumulation of fructose-1,6-bisphosphate (the substrate of FBPase) is an indication that the target enzyme in the gluconeogenic pathway, FBPase, is inhibited.

Example E: Chemical Stability Aim: To assess the stability of prodrugs 50.6, 50.9, 50.15, and 50.20 in a phosphate \O buffered, aqueous solution at neutral pH.

Methods: A 50 or 100 4g/mL solution of prodrug in potassium phosphate buffer at pH 7 (room temperature) was sampled daily for up to 10 days. Samples were analyzed by reverse phase HPLC with use of a Beckman Ultrasphere C18 column (4.6 X 250 mm). The column was equilibrated and eluted with a gradient from 50 mM sodium phosphate pH 5.5 to acetonitrile at a flow rate of 1.5 mL/min. Detection was at 300 or 315 nm, column temperature at 40 0 C. Under these conditions, the prodrugs were well separated from parent compound standards; the retention time for the prodrugs was between 16 and 18 minutes, whereas the parent compounds, 3.1 and 3.58 (non-HBr salt), eluted at 9 and 10 minutes, respectively.

Results: The prodrugs evaluated exhibited good stability at neutral pH. Less than decomposition of the prodrugs was noted over a 4 day incubation period. The t90's for 50.6, 50.9, 50.15, and 50.20 at pH 7 were thus >96 hours.

Example F: Estimation of Oral Bioavailability in the Rat Aim: To estimate the oral bioavailability of prodrugs by means of the urinary parent compound excretion method in the rat.

Methods: Prodrugs were dissolved in 10% ethanol/90% polyethylene glycol (mw 400) and administered by oral gavage at doses of 10 to 40 mg/kg parent compound equivalents to 6-hour fasted, Sprague Dawley rats (220-240 Parent compounds were typically dissolved in deionized water, neutralized with sodium hydroxide, and then administered via the tail vein at -10 mg/kg to rats that were briefly anesthetized with halothane. The rats were subsequently placed in metabolic cages and urine was collected for 24 hours. The quantity of parent compound excreted into urine was determined by HPLC analysis. Analysis was performed as described in Example E. The percentage oral bioavailability was estimated by comparison of the recovery in urine of the parent compound generated from the prodrug administered orally, to that recovered in urine following intravenous administration of unsubstituted parent compound.

Results: The estimated oral bioavailability of select prodrugs is shown below.

Methods: Prodrugs were administered orally at 10 mg/kg to fed rats instrumented with tail artery catheters. At appropriate time points following drug administration, blood samples were removed via the tail vein catheters. Plasma was prepared from the samples by centrifugation and plasma protein subsequently precipitated by addition of methanol to The methanolic extracts were clarified by centrifugation and then analyzed for prodrug and parent compound content by HPLC as described in Example E. Pharmacokinetic parameters were calculated from the parent compound plasma concentration-time profiles using noncompartmental analysis (WinNonLin v. 1.1 software).

Results: Prodrugs were not detected in plasma indicating rapid in vivo conversion to their respective parent compounds. Pharmacokinetic parameters are summarized below.

Methods: ZDF rats were purchased from Genetics Inc (Indianapolis, Indiana) at 8 weeks of age. Animals were maintained under standard vivarium conditions and provided with Purina 5008 chow and water ad libitum. At 10-12 weeks of age, rats with blood glucose levels >500 mg/dl were selected and dosed orally either with vehicle (PEG 400), or prodrug mg/kg). Blood glucose levels were monitored at regular intervals for 6 hours following dosing. Blood samples were taken from tail vein nicks and analyzed by means of a HemoCue glucose analyzer (Hemocue, Mission Viejo, CA). Statistical analysis was performed using the Student's t test. Means standard error of the means are shown.

Results: The three prodrugs were orally efficacious as indicated by the significant blood glucose lowering effects observed (see table below).

Methods: ZDF rats (10 weeks of age) were maintained either on powdered Purina 5008 rat-chow (n=10) or the same powdered chow supplemented with 0.4% 50.6 (n 8).

Blood glucose measurements were made as described in Example E at baseline and at weekly intervals thereafter for a total of 3 weeks. Statistical analysis was performed using the Student's t test. Means standard error of the means are shown.

Results: As illustrated in the table below, efficacy was maintained throughout the 3week treatment period, with 45% blood glucose lowering evident in the drug treated group (relative to vehicle) at the end of the study.

The column was equilibrated with 20 mM potassium phosphate, pH 6.2 and eluted with a linear gradient of 0-60% acetonitrile over 20 minutes at a 194 flow rate of 1.5 mLmin and at a temperature of40 0 C. UV absorbance was monitored at 300 nM. Exposure of 50.6 (100 pM) to the plasma samples resulted in the formation of a single metabolite. This metabolite had the same retention time and UV spectrum as a product formed following incubation of the prodrug with pig liver esterase (Sigma Chemical Co, MO), suggesting that it was a product of an esterase-catalyzed reaction. The metabolite formed in rat plasma was collected and subjected to mass spectrum analysis at Mass Consortium Corporation (San Diego, CA). The sample yielded a negative ion peak at 372, indicating that the metabolite formed had a molecular weight of 373. This molecular weight is consistent with that of a monophosphoramidate intermediate. This intermediate is likely formed via a reaction mechanism in which the prodrug first undergoes full de-esterification followed by intramolecular, hydrolytic cleavage of one of the amino acyl substituents.

Formation of the postulated monophosphoramidate intermediate was confirmed following the synthesis of a synthetic standard, Compound C. The standard had the identical HPLC and UV profile as the metabolite formed in plasma samples.

Example K: Metabolism of 50.6 in Human Hepatocytes Cryopreserved human hepatocytes were obtained from In Vitro Technologies and thawed according to the vendor's recommendations. Cells were incubated at 37 0 C in a Krebs-bicarbonate based buffer containing 50.6 at 10 pM. At various time points over the course of 4 hours, aliquots of cells were removed and extracted by addition of methanol to 60%. Cell extracts were clarified by centrifugation and analyzed by reverse phase HPLC with use of a Beckman Ultrasphere ODS column (4.6 x 150 mm) equipped with an Alltech All- Guard column. The column was equilibrated with 20 mM potassium phosphate, pH 6.2 and eluted with a linear gradient of 0-60% acetonitrile over 20 minutes at a flow rate of mL/min and at a temperature of40 0 C. UV absorbance was monitored at 300 nM. 50.6, Compound C, and 3.1 were quantified by comparison to authentic standards. Disappearance of 50.6 was rapid and essentially complete within 60 minutes of incubation. Two metabolites of 50.6 were detected: Compound C and 3.1. The initial rate of 3.1 formation was 195 24 pmol/million cells/minute. This study indicates that 50.6 is converted to the active FBPase inhibitor, 3.1, in intact human hepatocytes.

Example L: Structure Activity Relationship of Human Liver Phosphoramidase Human liver, purchased from the Anatomic Gift Foundation (Laurel, MD), was homogenized in Krebs-bicarbonate buffer and clarified by a slow-speed centrifugation.

Prodrug metabolism was evaluated in reaction mixtures containing human liver homogenate (4 mgs protein), 50 mM Tris-HC1, pH 7.4, 10 mM MgC12, and 10 mM dithiothreitol. At various time intervals over the course of 2 hours, aliquots were removed from the reaction mixtures and deproteinated by addition of methanol to 60%. Following clarification by centrifugation, metabolites were analyzed by reverse phase HPLC with use of a Beckman Ultrasphere ODS column (4.6 x 150 mm) equipped with an Alltech All-Guard column. The column was equilibrated with 20 mM potassium phosphate, pH 6.2 and eluted with a linear gradient of 0-60% acetonitrile over 20 minutes at a flow rate of 1.5 mL/min and at a temperature of40 0 C. UV absorbance was monitored at 300 nM. Most of the prodrugs evaluated were metabolized via a non-rate limiting, esterase-catalyzed step to their monophosphoramidate form within 5 minutes of incubation. The rate ofphosphonic acid appearance was therefore essentially a reflection of the rate of the final phosphoramidatecatalyzed cleavage step. Results for representative prodrugs for which the esterase-catalyzed step was non-rate limiting are shown below: Phosphoramidase Activity (Rate of 3.1 or 3.58 production, Prodrug nmoles/mn/mg liver protein) 50.6 0.022 50.8 0.019 50.10 0.005 50.12 0.022 50.20 0.085 Phosphoramidase Activity (Rate of 3.1 or 3.58 production, Prodrug nmoles/mn/mg liver protein) 50.19 0.029 52.8 0.025 52.12 0.032 52.16 0.033 The results indicate that human liver phosphoramidase readily cleaves the phosphorusnitrogen bond of a variety of phosphonic acid-monoamidate substrates, thereby liberating the free phosphonic acid FBPase inhibitor. The lowest P-N cleavage rate was observed with a secondary amine substrate, the monophosphoramidate of 50.10. The first step in prodrug activation, esterase-catalyzed de-esterification, was not rate-limiting for the majority of substrates evaluated.
