FIELD OF THE INVENTION The invention relates generally to phosphinate compounds with HCV inhibitory 10 activity. BACKGROUND OF THE INVENTION Hepatitis C is recognized as a chronic viral disease of the liver which is characterized by liver disease. Although drugs targeting the liver are in wide use and have shown 15 effectiveness, toxicity and other side effects have limited their usefulness. Inhibitors of HCV are useful to limit the establishment and progression of infection by HCV as well as in diagnostic assays for HCV. There is a need for new HCV therapeutic agents. The discussion of documents, acts, materials, devices, articles and the like is included 20 in this specification solely for the purpose of providing a context for the present invention. It is not suggested or represented that any or all of these matters formed part of the prior art base or were common general knowledge in the field relevant to the present invention as it existed before the priority date of each claim of this application. Where the terms "comprise", "comprises", "comprised" or "comprising" are used in 25 this specification (including the claims) they are to be interpreted as specifying the presence of the stated features, integers, steps or components, but not precluding the presence of one or more other features, integers, steps or components, or group thereof. la WO 2008/005565 PCT/US2007/015664 SUMMARY OF THE INVENTION In one embodiment the invention provides a compound of the invention which is a compound of formula I: Zi A AA3 II A3 N3 A R2 Z2e y 5 or a pharmaceutically acceptable salt, or prodrug thereof, wherein: R' is independently selected from H, alkyl, alkenyl, alkynyl, aryl, cycloalkyl, heterocycle, halogen, haloalkyl, alkylsulfonamido, arylsulfonamido, -C(O)NHS(0) 2 -, or -S(O) 2 -, optionally substituted with one or more A 3 ; 10 R 2 is selected from, a) -C(Y)(A3), b) (C2-1O)alkyl, (C3-7)cycloalkyl or (Cl-4)alkyl-(C3-7)cycloalkyl, where said cycloalkyl and alkyl-cycloalkyl may be optionally mono-, di- or tri-substituted with (Cl -3)alkyl, or 15 where-said alkyl, cycloalkyl and alkyl-cycloalkyl may optionally be mono- or di-substituted with substituents selected from hydroxy and 0-(C I -4)alkyl, or where each of said alkyl-groups may optionally be mono-, di- or tri-substituted with halogen,.or 20 where each of said cycloalkyl groups being 5-, 6- or 7-membered, one or two -CH 2 -groups not being directly linked to each other rmay be optionally substituted replaced by -0- such that the 0-atom is linked to the N atom to which R 2 is attached via at least two C-atoms, 25 c) phenyl, (Cl-3)alkyl-phenyl, heteroaryl or (CI-3)alkyl-heteroaryl, 2 WO 2008/005565 PCT/US2007/015664 wherein the heteroaryl-groups are 5- or 6-membered having from 1 to 3 beteroatoms selected from N, 0 and S, wherein said phenyl and heteroaryl groups may optionally be mono-, di- or trisubstituted with substituents selected from halogen, -OH, (Cl 5 4)alkyl, 0-(CI-4)alkyl, S-(CI-4)alkyl, -NH 2 , -CF 3 ,-NH((C1 4)alkyl) and -N((Cl-4)alkyl) 2 , -CONH 2 and -CONH-(Cl-4)alkyl; and wherein said (CI-3)alkyl may optionally be substituted with one or more halogen; or d) -S(O)2(A 3 ); 10 R 3 is H or (CI-6)alkyl; YI is independently 0, S, N(A 3 ), N(O)(A 3 ), N(OA 3 ), N(O)(OA 3 ) or N(N(A3)(A )); Z is 0, S, or NR3 Z' is selected from the following structures: HN-K Rb Rb R, L R.

The term "chiral" refers to molecules which have the property of non 20 superimposability of the mirror image partner, while the term "achiral" refers to molecules which are superimposable on their mirror image partner. The term "stereoisomers" refers to compounds which have identical chemical constitution, but differ with regard to the arrangement of the atoms or groups in space. 25 "Diastereomer" refers to a stereoisomer with two or more centers of chirality and whose molecules are not mirror images of one another. Diastereomers have different physical properties, e.g., melting points, boiling points, spectral properties, and reactivities. Mixtures of diastereomers may separate under high resolution analytical procedures such as electrophoresis and 30 chromatography. "Enantiomers" refer to two stereoisomers of a compound which are non superimposable mirror images of one another. 11 WO 2008/005565 PCT/US2007/015664 The term "treatment" or "treating," to the extent it relates to a disease or condition includes preventing the disease or condition from occurring, inhibiting the disease or condition, eliminating the disease or condition, and/or relieving one or more symptoms of the disease or condition. 5 The term "PRT" is selected from the terms "prodrug moiety" and "protecting group" as defined herein. Stereochemical definitions and conventions used herein generally follow S. P. Parker, Ed., McGraw-Hill Dictionary of Chemical Terms (1984) McGraw Hill Book Company, New York; and Eliel, E. and Wilen, S., Stereochemistry of 10 Organic Compounds (1994) John Wiley & Sons, Inc., New York. Many organic compounds exist in optically active forms, i.e., they have the ability to rotate the plane of plane-polarized light. In describing an optically active compound, the prefixes D and L or R and S are used to denote the absolute configuration of the molecule about its chiral center(s). The prefixes d and 1 or (+) and (-) are 15 employed to designate the sign of rotation of plane-polarized light by the compound, with (-) or 1 meaning that the compound is levorotatory. A compound prefixed with (+) or d is dextrorotatory. For a given chemical structure, these stereoisomers are identical except that they are mirror images of one another. A specific stereoisomer may also be referred to as an enantiomer, 20 and a mixture of such isomers is often called an enantiomeric mixture. A 50:50 mixture of enantiomers is referred to as a racemic mixture or a racemate, which may occur where there has been no stereoselection or stereospecificity in a chemical reaction or process. The terms "racemic mixture" and racematee" refer to an equimolar mixture of two enantiomeric species, devoid of optical activity. 25 The invention includes all stereoisomers of the compounds descibed herein. Prodrugs The term "prodrug" as used herein refers to any compound that when administered to a biological system generates the drug substance, I.e. active 30 ingredient, as a result of spontaneous chemical reaction(s), enzyme catalyzed chemical reaction(s), photolysis, and/or metabolic chemical reaction(s). A 12 WO 2008/005565 PCT/US2007/015664 prodrug is thus a covalently modified analog or latent form of a therapeutically active compound. "Prodrug moiety" refers to a labile functional group which separates from the active inhibitory compound during metabolism, systemically, inside a cell, by 5 hydrolysis, enzymatic cleavage, or by some other process (Bundgaard, Hans, "Design and Application of Prodrugs" in A Textbook of Drug Design and Development (1991), P. Krogsgaard-Larsen and H. Bundgaard, Eds. Harwood Academic Publishers, pp. 113-191). Enzymes which are capable of an enzymatic activation mechanism with the phosphonate prodrug compounds of 10 the invention include, but are not limited to, amidases, esterases, microbial enzymes, phospholipases, cholinesterases, and phosphases. Prodrug moieties can serve to enhance solubility, absorption and lipophilicity to optimize drug delivery, bioavailability and efficacy. A prodrug moiety may include an active metabolite or drug itself. 15 Exemplary prodrug moieties include the hydrolytically sensitive or labile acyloxymethyl esters -CH 2

Sci. 72: 324; also US Patent Nos. 4816570, 4968788, 5663159 and 5792756. 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, the alkoxycarbonyloxyalkyl ester (carbonate); may also enhance oral bioavailability 25 as a prodrug moiety in the compounds of the combinations of the invention. An exemplary acyloxymethyl ester is pivaloyloxymethoxy, (POM)

3 . Aryl esters of phosphorus groups, especially phenyl esters, are reported 30 to enhance oral bioavailability (De Lombaert et al. (1994) J. Med. Chem. 37: 498). Phenyl esters containing a carboxylic ester ortho to a phosphate have also been described (Khamnei and Torrence, (1996) J. Med. Chem. 39:4109-4115). 13 WO 2008/005565 PCT/US2007/015664 Benzyl esters are reported to generate parent phosphonic acids. In some cases, substituents at the ortho- orpara-position may accelerate the hydrolysis. Benzyl analogs with an acylated phenol or an alkylated phenol may generate the phenolic compound through the action of enzymes, e.g., esterases, oxidases, etc., 5 which in turn undergoes cleavage at the benzylic C-0 bond to generate phosphoric acid and a quinone methide intermediate. Examples of this class of prodrugs are described by Mitchell et al. (1992) J. Chem. Soc. Perkin Trans. II 2345; Glazier WO 91/19721. Still other benzylic prodrugs have been described containing a carboxylic ester-containing group attached to the benzylic 10 methylene (Glazier WO 91/19721). Thio-containing prodrugs are reported to be useful for the intracellular delivery of phosphonate 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. Deesterification or reduction of the disulfide generates the free thio intermediate 15 which subsequently breaks down to the phosphoric acid and episulfide (Puech et al. (1993) Antiviral Res., 22: 155-174; Benzaria et al. (1996) J. Med. Chem. 39: 4958). Protecting Groups In the context of the present invention, protecting groups include prodrug 20 moieties and chemical protecting groups. "Protecting group" refers to a moiety of a compound that masks or alters the properties of a functional group or the properties of the compound as a whole. Chemical protecting groups and strategies for protection/deprotection are well known in the art. See e.g., Protective Groups in Organic Chemistry 25 Theodora W. Greene, John Wiley 9: Sons, Inc., New York, 1991. Protecting groups are often utilized to mask the reactivity of certain functional groups, to assist in the efficiency of desired chemical reactions, e.g.,.making and breaking chemical bonds in an ordered and planned fashion. Protection of functional groups of a compound alters other physical properties besides the reactivity of 30 the protected functional group, such as the polarity, lipophilicity (hydrophobicity), and other properties which can be measured by common analytical tools. Chemically protected intermediates may themselves be 14 WO 2008/005565 PCT/US2007/015664 biologically active or inactive. Protected compounds may also exhibit altered, and in some cases, optimized properties in vitro and in vivo, such as passage through cellular membranes and resistance to enzymatic degradation or sequestration. In this S role, protected compounds with intended therapeutic effects may be referred to as prodrugs. Another function of a protecting group is to convert the parental drug into a prodrug, whereby the parental drug is released upon conversion of the prodrug in vivo. Because active prodrugs may be absorbed more effectively than the parental drug, prodrugs may possess greater potency in vivo than the 10 parental drug. Protecting groups are removed either in vitro, in the instance of chemical intermediates, or In vivo, in the case of prodrugs. With chemical intermediates, it is not particularly important that the resulting products after deprotection, e.g., alcohols, be physiologically acceptable, although in general it is more desirable if the products are pharmacologically innocuous. 15 Protecting groups are available, commonly known and used, and are optionally used to prevent side reactions with the protected group during synthetic procedures, i.e. routes or methods to prepare the compounds of the invention. For the most part the decision as to which groups to protect, when to do so, and the nature of the chemical protecting group "PG" will be dependent 20 upon the chemistry of the reaction to be protected against (e.g., acidic, basic, oxidative, reductive or other conditions) and the intended direction of the synthesis. The PG groups do not need to be, and generally are not, the same if the compound is substituted with multiple PG. In general, PG will be used to protect functional groups such as carboxyl, hydroxyl, thio, or amino groups and 25 to thus prevent side reactions or to otherwise facilitate the synthetic efficiency. The order of deprotection to yield free, deprotected groups is dependent upon the intended direction of the synthesis and the reaction conditions to be encountered, and may occur in any order as determined by the artisan. Various functional groups of the compounds of the invention may be 30 protected. For example, protecting groups for -OH groups (whether hydroxyl, carboxylic acid, phosphonic acid, or other functions) include "ether- or ester forming groups". Ether- or ester-forming groups are capable of functioning as 15 WO 2008/005565 PCT/US2007/015664 chemical protecting groups in the synthetic schemes set forth herein. However, some hydroxyl and thio protecting groups are neither ether- nor ester-forming groups, as will be understood by those skilled in the art, and are included with amides, discussed below. 5 A very large number of hydroxyl protecting groups and amide-forning groups and corresponding chemical cleavage reactions are described in Protective Groups in Oranic Synthesis. Theodora W. Greene (John Wiley & Sons, Inc., New York, 1991, ISBN 0-471-62301-6) ("Greene").

"Ether forming group" means a group which is capable of forming a stable, covalent bond between the parental molecule and a group having the formula: S-O-va(1) 3 S-O-a( 1 )(v 2 ) , S-O-Va(V 3 ) 20 S-O-b(v1) 2 , S-O-Vb(v 2 ) , or S-0-V(v1) Wherein Va is a tetravalent atom typically selected from C and Si; Vb is a trivalent atom typically selected from B, Al, N, and P, more typically N and P; Vc is a divalent atom typically selected from 0, S, and Se, more typically S; VI is a group bonded to Va, Vb or Vc by a stable, single covalent bond, typically 25 V1 is A 2 groups; V2 is a group bonded to Va or Vb by a stable, double covalent bond, provided that V2 is not =0, =S or =N-, typically V2 is =C(V1)2 wherein VI is as described above; and V3 is a group bonded to Va by a stable, triple covalent bond, typically V3 is JC(V1) wherein V1 is as described above. "Ester-forming group" means a group which is capable of forming a 16 WO 20081005565 PCT/US2007/015664 stable, covalent bond between the parental molecule and a group having the formula: S-0-v(v 1 )v 4 ) , S-o-V4 ) , S--Vd(V1) 2 (V4) -O-Vd(V4)2, S-0-Ve(V) 3

Protecting groups for -OH functions (whether hydroxy, acid or other 10 functions) are embodiments of "ether- or ester-forming groups". Particularly of interest are ether- or ester-forming groups that are capable of functioning as protecting groups in the synthetic schemes set forth herein. However, some hydroxyl and thio protecting groups are neither ether- nor ester-forming groups, as will be understood by those skilled in the art, and are included with amides, 15 discussed below, and are capable of protecting hydroxyl or thin groups such that hydrolysis from the parental molecule yields hydroxyl or thio. In its ester-forming role, A3 or A 2 typically is bound to any acidic group such as, by way of example and not limitation, a -CO2H or -C(S)OH group, thereby resulting in -C02 A 2 or -C0 2

As further embodiments, Table A lists examples of A 2 ester moieties that for example can be bonded via oxygen to -C(O)O- and -P(O)(R)(O-) groups. 5 Several amidates also are shown, which are bound directly to -C(O)- or -P(O)2. Esters of structures 1-5, 8-10 and 16, 17, 19-22 are synthesized by reacting the compound herein having a free hydroxyl with the corresponding halide (chloride or acyl chloride and the like) and N ,N-dicylohexyl-N-morpholine carboxamidine (or another base such as DBU, triethylamine, CsCO3, NN-dinethylaniline and 10 the like) in DMF (or other solvent such as acetonitrile or N-methylpyrrolidone). When A 3 is phosphonate, the esters of structures 5-7, 11, 12, 21, and 23-26 are synthesized by reaction of the alcohol or alkoxide salt (or the corresponding amines in the case of compounds such as 13, 14 and 15) with the monochlorophosphonate or dichlorophosphonate (or another activated 15 phosphonate).

6 Hs. 5 For prodrug purposes, the ester typically chosen is one heretofore used for antiviral drugs, in particular the cyclic carbonates, double esters, or the phthalidyl, aryl or alkyl esters. As noted A3 or A2 groups optionally are used to prevent side reactions with the protected group during synthetic procedures, so they function as 10 protecting groups (PRT) during synthesis. For the most part the decision as to which groups to protect, when to do so, and the nature of the PRT will be dependent upon the chemistry of the reaction to be protected against (e.g., acidic, basic, oxidative, reductive or other conditions) and the intended direction of the synthesis. The PRT groups do not need to be, and generally are not, the same if 15 the compound is substituted with multiple PRT. In general, PRT will be used to protect carboxyl, hydroxyl or amino groups. The order of deprotection to yield free groups is dependent upon the intended direction of the synthesis and the reaction conditions to be encountered, and may occur in any order as determined by the artisan. 20 In some embodiments the A 2 protected acidic group is an ester of the acidic group and A 2 is the residue of a hydroxyl-containing functionality. In other embodiments, an amino compound is used to protect the acid functionality. The residues of suitable hydroxyl or amino-containing functionalities are set forth above or are found in WO 95/07920. Of particular interest are the residues 25 of amino acids, amino acid esters, polypeptides, or aryl alcohols. Typical amino acid, polypeptide and carboxyl-esterified amino acid residues are described on pages 11-18 and related text of WO 95/07920 as groups L1 or L2. WO 95/07920 expressly teaches the amidates of phosphonic acids, but it will be understood that such amidates are formed with any of the acid groups set forth 30 herein and the amino acid residues set forth in WO 95/07920. Typical A 2 esters for protecting A 3 acidic functionalities are also described in WO 95/07920, again understanding that the same enters can be 22 WO 2008/005565 PCT/US20071015664 formed with the acidic groups herein as with the phosphonate of the'920 publication. Typical ester groups are defined at least on WO 95/07920 pages 89 93 (under R 3 1 or R 3 5 ), the table on page 105, and pages 21-23 (as R'). Of particular interest are esters of unsubstituted aryl such as phenyl or arylalkyl 5 such benzyl, or hydroxy-, halo-, alkoxy-, carboxy- and/or alkylestercarboxy substituted aryl or alkylaryl, especially phenyl, ortho-ethoxyphenyl, or CI-C4 alkylestercarboxyphenyl (salicylate CI-C 12 alkylesters). The protected acidic groups A 3 , particularly when using the esters or amides of WO 95/07920, are useful as prodrugs for oral administration. 10 However, it is not essential that the A 3 acidic group be protected in order for the compounds of this invention to be effectively administered by the oral route. When the compounds of the invention having protected groups, in particular amino acid amidates or substituted and unsubstituted aryl esters are administered systemically or orally they are capable of hydrolytic cleavage In vivo to yield the 15 free acid. One or more of the acidic hydroxyls are protected. If more than one acidic hydroxyl is protected then the same or a different protecting group is employed, e.g., the esters may be different or the same, or a mixed amidate and ester may be used. 20 Typical A 2 hydroxy protecting groups described in Greene (pages 14 118) include Ethers (Methyl); Substituted Methyl Ethers (Methoxymethyl, Methylthiomethyl, t-Butylthiomethyl, (Phenyldimethylsilyl)metboxymethyl, Benzyloxymethyl, p-Methoxybenzyloxymethyl, (4-Methoxyphenoxy)methyl, Guaiacolmethyl, t-Butoxymethyl, 4-Pentenyloxymethyl, Siloxymethyl, 2 25 Methoxyethoxymethyl, 2,2,2-Trichlotoethoxymethyl, Bis(2 chloroethoxy)methyl, 2-(Trimethylsilyl)ethoxymethyl, Tetrahydropyranyl, 3 Bromotetrahydropyranyl, Tetrahydropthiopyranyl, 1-Methoxycyclohexyl, 4 Methoxytetrahydropyranyl, 4-Methoxytetrahydrothiopyranyl, 4 Methoxytetrahydropthiopyranyl SS-Dioxido, 1-[(2-Chloro-4-methyl)phenyl]-4 30 methoxypiperidin-4-yl, 35, 1,4-Dioxan-2-yl, Tetrahydrofuranyl, Tetrahydrothiofuranyl, 2,3,3a,4,5,6,7,7a-Octahydro-7,8,8-trimethyl-4,7 methanobenzofuran-2-yl)); Substituted Ethyl Ethers (1-Ethoxyethyl, 1-(2 23 WO 2008/005565 PCT/US2007/015664 Chloroethoxy)ethyl, 1-Methyl-1-methoxyethyl, 1-Methyl-I-benzyloxyethyl, 1 Methyl-1-benzyloxy-2-fluoroethyl, 2,2,2-Trichloroethyl, 2-Trimethylsilylethyl, 2-(Phenylselenyl)ethyl, t-Butyl, Allyl,p-Chlorophenyl,p-Methoxyphenyl, 2,4 Dinitrophenyl, Benzyl); Substituted Benzyl Ethers (p-Methoxybenzyl, 3,4 5 Dimethoxybenzyl, o-Nitrobenzyl,p-Nitrobenzyl,p-Halobenzyl, 2,6 Dichlorobenzyl, p-Cyanobenzfl, p-Phenylbenzyl, 2- and 4-Picolyl, 3-Methyl-2 picolyl N-Oxido, Diphenylmethyl, pp'-Dinitrobenzhydryl, 5-Dibenzosuberyl, Triphenylmethyl, a-Naphthyldiphenylmethyl,p-methoxyphenyldiphenylmethyl, Di(p-methoxyphenyl)phenylmethyl, Tri(p-methoxyphenyl)methyl, 4-(4' 10 Bromophenacyloxy)phenyldiphenylmethyl, 4,4',4"-Tris(4,5 dichlorophthalimidophenyl)methyl, 4,4',4"-Tris(levulinoyloxyphenyl)methyl, 4,4',4"-Tris(benzoyloxyphenyl)methyl, 3-(Imidazol-1-ylmethyl)bis(4',4" dimethoxyphenyl)methyl, 1,1-Bis(4-methoxyphenyl)-1'-pyrenylmethyl, 9 Anthryl, 9-(9-Phenyl)xanthenyl, 9-(9-Phenyl-1 0-oxo)anthryl, 1,3 15 Benzodithiolan-2-yl, Benzisothiazolyl SS-Dioxido); Silyl Ethers (Trimethylsilyl, Triethylsilyl, Triisopropylsilyl, Dimethylisopropylsilyl, Diethylisopropylsily, Dimethylthexylsilyl, t-Butyldimethylsilyl, t-Butyldiphenylsilyl, Tribenzylsilyl, Tri-p-xylylsilyl, Triphenylsilyl, Diphenylmethylsilyl, t Butylmethoxyphenylsilyl); Esters (Formate, Benzoylformate, Acetate, 20 Choroacetate, Dichloroacetate, Trichloroacetate, Trifluoroacetate, Methoxyacetate, Triphenylmethoxyacetate, Phenoxyacetate, p Chlorophenoxyacetate, p-poly-Phenylacetate, 3-Phenylpropionate, 4 Oxopentanoate (Levulinate), 4,4-(Ethylenedithio)pentanoate, Pivaloate, Adamantoate, Crotonate, 4-Methoxycrotonate, Benzoate,p-Phenylbenzoate, 25 2,4,6-Trimethylbenzoate (Mesitoate)); Carbonates (Methyl, 9-Fluorenylmethyl, Ethyl, 2,2,2-Trichloroethyl, 2-(Trimethylsilyl)ethyl, 2-(Phenylsulfonyl)ethyl, 2 (Triphenylphosphonio)ethyl, Isobutyl, Vinyl, Allyl, p-Nitrophenyl, Benzyl, p Methoxybenzyl, 3,4-Dimethoxybenzyl, o-Nitrobenzyl,p-Nitrobenzyl, S-Benzyl Thiocarbonate, 4-Ethoxy-1-naphthyl, Methyl Dithiocarbonate); Groups With 30 Assisted Cleavage (2-Iodobenzoate, 4-Azidobutyrate, 4-Niotro-4 methylpentanoate, o-(Dibromomethyl)benzoate, 2-Formylbenzenesulfonate, 2 (Methylthiomethoxy)ethyl Carbonate, 4-(Methylthiomethoxy)butyrate, 2 24 WO 2008/005565 PCT/US2007/015664 (Methylthiomethoxymethyl)benzoate); Miscellaneous Esters (2,6-Dichloro-4 methylphenoxyacetate, 2,6-Dichloro-4-(1,1,3,3 tetramethylbutyl)phenoxyacetate, 2,4-Bis(1,1 -dimethylpropyl)phenoxyacetate, Chorodiphenylacetate, Isobutyrate, Monosuccinoate, (E)-2-Methyl-2-butenoate 5 (Tigloate), o-(Methoxycarbonyl)benzoate, p-poly-Benzoate, a-Naphthoate, Nitrate, Alkyl N,N,N',N'-Tetramethylphosphorodiamidate, N-Phenylcarbamate, Borate, Dimethylphosphinothioyl, 2,4-Dinitrophenylsulfenate); and Sulfonates (Sulfate, Methanesulfonate (Mesylate), Benzylsulfonate, Tosylate).

More typically, protected amino groups include carbamates and amides, 10 still more typically, -NHC(O)R' or -N=CRIN(R!) 2 . Another protecting group, also useful as a prodrug at the A 3 site, particularly for amino or -NH(R5), is: 0 Wa see for example Alexander, J. et al.; J. Med. Chem. 1996, 39, 480-486.

A

2 is also H or the residue of an amino-containing compound, in 15 particular an amino acid, a polypeptide, a protecting group, -NHSO2R4, NHC(O)R4, -N(R4)2, NH2 or -NH(R4)(H), whereby for example the carboxyl or phosphonic acid groups of A 3 are reacted with the amine to form an amide, as in -C(O) A 2 , -P(O)( A 2

)

2 or -P(OXOH)( A 2 ). In general, A 2 has the structure R17C(O)CH(RI6)NH-, where Ri 7 is OH, 0 A 2 , OR5, an amino acid or a 20 polypeptide residue. Amino acids are low molecular weight compounds, on the order of less than about 1,000 MW, that contain at least one amino or iniino group and at least one carboxyl group. Generally the amino acids will be found in nature, i.e., can be detected in biological material such as bacteria or other microbes, plants, 25 animals or man. Suitable amino acids typically are alpha amino acids, i.e. compounds characterized by one amino or imino nitrogen atom separated from the carbon atom of one carboxyl group by a single substituted or unsubstituted alpha carbon atom. Of particular interest are hydrophobic residues such as mono-or di-alkyl or aryl amino acids, cycloalkylamino acids and the like. These 29 WO 2008/005565 PCT/US2007/015664 residues contribute to cell permeability by increasing the partition coefficient of the parental drug. Typically, the residue does not contain a sulfhydryl or guanidino substituent. Naturally-occurring amino acid residues are those residues found 5 naturally in plants, animals or microbes, especially proteins thereof. Polypeptides most typically will be substantially composed of such naturally occurring amino acid residues. These amino acids are glycine, alanine, valine, leucine, isoleucine, serine, threonine, cysteine, methionine, glutamic acid, aspartic acid, lysine, hydroxylysine, arginine, histidine, phenylalanine, tyrosine, 10 tryptophan, proline, asparagine, glutamine and hydroxyproline. When A 2 are single amino acid residues or polypeptides they usually are substituted at A 3 . These'conjugates are produced by forming an amide bond between a carboxyl group of the amino acid (or C-terminal amino acid of a polypeptide for example) and amino nitrogen. Similarly, conjugates are formed 15 between A 3 and an amino group of an amino acid or polypeptide. Generally, only one of any site in the parental molecule is amidated with an amino acid as described herein, although it is within the scope of this invention to introduce amino acids at more than one permitted site. Usually, a carboxyl group of A 3 is amidated with an amino acid. In general, the a-amino or a-carboxyl group of the 20 amino acid or the terminal amino or carboxyl group of a polypeptide are bonded to the parental functionalities, i.e., carboxyl or amino groups in the amino acid side chains generally are not used to form the amide bonds with the parental compound (although these groups may need to be protected during synthesis of the conjugates as described further below). 25 With respect to the carboxyl-containing side chains of amino acids or polypeptides it will be understood that the carboxyl group optionally will be blocked, e.g. by A 2 , esterified with A 2 or amidated with A 2 . Similarly, the amino side chains R16 optionally will be blocked with A 2 or substituted with RS. Such ester or aide bonds with side chain amino or carboxyl groups, like 30 the esters or amides with the parental molecule, optionally are hydrolyzable in vivo or in vitro under acidic (pH <3) or basic (pH >10) conditions. Alternatively, they are substantially stable in the gastrointestinal tract of humans 30 WO 2008/005565 PCT/US2007/015664 but are hydrolyzed enzymatically in blood or in intracellular environments. The esters or amino acid or polypeptide amidates also are useful as intermediates for the preparation of the parental molecule containing free amino or carboxyl groups. The free acid or base of the parental compound, for example, is readily 5 formed from the esters or amino acid or polypeptide conjugates of this invention by conventional hydrolysis procedures. When an amino acid residue contains one or more chiral centers, any of the D, L, meso, threo or erythro (as appropriate) racemates, scalemates or mixtures thereof may be used. In general, if the intermediates are to be 10 hydrolyzed non-enzymatically (as would be the case where the amides are used as chemical intermediates for the free acids or free amines), D isomers are useful. On the other hand, L isomers are more versatile since they can be susceptible to both non-enzymatic and enzymatic hydrolysis, and are more efficiently transported by amino acid or dipeptidyl transport systems in the 15 gastrointestinal tract. Examples of suitable amino acids whose residues are represented by A 2 include the following: Glycine; Aminopolycarboxylic acids, e.g., aspartic acid, p-hydroxyaspartic acid, 20 glutamic acid, p-hydroxyglutamic acid, p-methylaspartic acid, p-methylglutamic acid, 0, p-dimethylaspartic acid, y-hydroxyglutamic acid, p,y-dihydroxyglutamic acid, p-phenylglutamic acid, y-methyleneglutamic acid, 3-aminoadipic acid, 2 aminopimelic acid, 2-aminosuberic acid and 2-aminosebacic acid; Amino acid amides such as glutamine and asparagine; 25 Polyamino- or polybasic-monocarboxylic acids such as arginine, lysine, P-aninoalanine, y-aminobutyrine, ornithine, citruline, homoarginine, homocitrulline; hydroxylysine, allohydroxylsine and diaminobutyric acid; *Other basic amino acid residues such as histidine; Diaminodicarboxylic acids such as c,a'-diaminosuccinic acid, a, a' 30 diaminoglutaric acid, a,a'-diaminoadipic acid, a,a'-diaminopinelic acid, a,a' diamino-p-hydroxypimelic acid, a,i'-diaminosuberic acid, a, a'-diaminoazelaic acid, and a,a'-diaminosebacic acid; 31 WO 2008/005565 PCT/US2007/015664 Imino acids such as proline, hydroxyproline, allohydroxyproline, y methylproline, pipecolic acid, 5-hydroxypipecolic acid, and azetidine-2 carboxylic acid; A mono- or di-alkyl (typically CI - C 8 branched or normal) amino acid 5 such as alanine, valine, leucine, allylglycine, butyrine, norvaline, norleucine, heptyline, a-methylserine, a-amino-a-methyl-y-hydroxyvaleric acid, a-amino- a methyl-8-hydroxyvaleric acid, a-amino- a-methyl-e-hydroxycaproic acid, isovaline, a-methylglutamic acid, a-aminoisobutyric acid, a-aminodiethylacetic acid, a-aminodiisopropylacetic acid, a-aminodi-n-propylacetic acid, a 10 aminodiisobutylacetic acid, a-aminodi-n-butylacetic acid, a aminoethylisopropylacetic acid, a-amino-n-propylacetic acid, a aminodiisoamyacetic acid, a-methylaspartic acid, a-methylglutamic acid, 1 aminocyclopropane-l-carboxylic acid, isoleucine, alloisoleucine, tert-leucine, f methyltryptophan and a-amino-P-ethyl- p-phenylpropionic acid; 15 0-phenylserinyl; Aliphatic a-amino-p-hydroxy acids such as serine, p hydroxyleucine, P-hydroxynorleucine, p-hydroxynorvaline, and a-amino-p hydroxystearic acid; a-Amino, a-, 1-, 8- or 6-hydroxy acids such as homoserine, y 20 hydroxynorvaline, 6-hydroxynorvaline and epsilon-hydroxynorleucine residues; canavine and canaline; y-hydroxyornithine; 2-hexosaminic acids such as D-glucosaminic acid or D galactosaminic acid; a-Amino-3-thiols such as penicillamine, 0-thiolnorvaline or 0 25 thiolbutyrine; Other sulfur containing amino acid residues including cysteine; homocystine, 0-phenylmethionine, methionine, S-allyl-L-cysteine sulfoxide, 2 thiolhistidine, cystathionine, and thiol ethers of cysteine or homocysteine; Phenylalanine, tryptophan and ring-substituted a-amino acids 30 such as the phenyl- or cyclohexylamino acids a-aminophenylacetic acid, a aminocyclohexylacetic acid and a-amino-p-cyclohexylpropionic acid; phenylalanine analogues and derivatives comprising aryl, lower alkyl, hydroxy, 32 WO 2008/005565 PCT/US2007/015664 guanidino, oxyalkylether, nitro, sulfur or halo-substituted phenyl (e.g., tyrosine, methyltyrosine and o-chloro-, p-chloro-, 3,4-dicloro, o-, m- or p-methyl-, 2,4,6 trimethyl-, 2-ethoxy-5-nitro-, 2-hydroxy-5-nitro- and p-nitro-phenylalanine); furyl-, thienyl-, pyridyl-, pyrimidinyl-, purinyl- or naphthyl-alanines; and 5 tryptophan analogues and derivatives including kynurenine, 3 hydroxykynurenine, 2-hydroxytryptophan and 4-carboxytryptophan; at-Amino substituted amino acids including sarcosine (N methylglycine), N-benzylglycine, N-methylalanine, N-benzylalanine, N methylphenylalanine, N-benzylphenylalanine, N-methylvaline and N 10 benzylvaline; and a-Hydroxy and substituted a-hydroxy amino acids including serine, threonine, allothreonine, phosphoserine and phosphothreonine. Polypeptides are polymers of amino acids in which a carboxyl group of one amino acid monomer is bonded to an amino or imino group of the next 15 amino acid monomer by an amide bond. Polypeptides include dipeptides, low molecular weight polypeptides (about 1500-5000MW) and proteins. Proteins optionally contain 3, 5, 10, 50, 75, 100 or more residues, and suitably are substantially sequence-homologous with human, animal, plant or microbial proteins. They include enzymes (e.g., hydrogen peroxidase) as well as 20 immunogens such as KLH, or antibodies or proteins of any type against which one wishes to raise an immune response. The nature and identity of the polypeptide may vary widely. The polypeptide amidates are useful as immunogens in raising antibodies against either the polypeptide (if it i0 not immunogenic in the animal to which it 25 is administered) or against the epitopes on the remainder of the compound of this invention. Antibodies capable of binding to the parental non-peptidyl compound are used to separate the parental compound from mixtures, fori example in diagnosis or manufacturing of the parental compound. The conjugates of parental 30 compound and polypeptide generally are more immunogenic than the polypeptides in closely homologous animals, and therefore make the polypeptide more immunogenic for facilitating raising antibodies against it. Accordingly, the 33 WO 2008/005565 PCT/US2007/015664 polypeptide or protein may not need to be immunogenic in an animal typically used to raise antibodies, e.g., rabbit, mouse, horse, or rat, but the final product conjugate should be immunogenic in at least one of such animals. The polypeptide optionally contains a peptidolytic enzyme cleavage site at the 5 peptide bond between the first and second residues adjacent to the acidic heteroatom. Such cleavage sites are flanked by enzymatic recognition structures, e.g. a particular sequence of residues recognized by a peptidolytic enzyme. Peptidolytic enzymes for cleaving the polypeptide conjugates of this 10 invention are well known, and in particular include carboxypeptidases. Carboxypeptidases digest polypeptides by removing C-terminal residues, and are specific in many instances for particular C-terminal sequences. Such enzymes and their substrate requirements in general are well known. For example, a dipeptide (having a given pair of residues and a free carboxyl terminus) is 15 covalently bonded through its a-amino group to the phosphorus or carbon atoms of the compounds herein. In embodiments where A 3 is phosphonate it is expected that this peptide will be cleaved by the appropriate peptidolytic enzyme, leaving the carboxyl of the proximal amino acid residue to autocatalytically cleave the phosphonoamidate bond. 20 Suitable dipeptidyl groups (designated by their single letter code) are AA, AR, AN, AD, AC, AE, AQ, AG, AH, Al, AL, AK, AM, AF, AP, AS, AT, AW, AY, AV, RA, RR, RN, RD, RC, RE, RQ, RG, RH, RI, RL, RK, RM, RF, RP, RS, RT, RW, RY, RV, NA, NR, NN, ND, NC, NE, NQ, NG, NH, NI, NL, NK, NM, NF, NP, NS, NT, NW, NY, NV, DA, DR, DN, DD, DC, DE, DQ, DG, 25 DH, DI, DL, DK, DM, DF, DP, DS, DT, DW, DY, DV, CA, CR, CN, CD, CC, CE, CQ, CG, CH, CI, CL, CK, CM, CF, CP, CS, CT, CW, CY, CV, EA, ER, EN, ED, EC, EE, EQ, EG, EH, EI, EL, EK, EM, EF, EP, ES, ET, EW, EY, EV, QA, QR, QN, QD, QC, QE, QQ, QG, QH, QI, QL, QK, QM, QF, QP, QS, QT, QW, QY, QV, GA, GR, GN, GD, GC, GE, GQ, GG, GH, GI, GL, OK, GM, GF, 30 GP, GS, GT, GW, GY, GV, HA, HR, HN, HD, HC, HE, HQ, HG, HH, HI, HL, HK, HM, HF, HP, HS, HT, HW, HY, HV, IA, IR, IN, ID, IC, IE, IQ, IG, IH, H1, IL, IK, IM, IF, IP, IS, IT, 1W, IY, IV, LA, LR, LN, LD, LC, LE, LQ, LG, LH, 34 WO 2008/005565 PCT/US2007/015664 LI, LL, LK, LM, LF, LP, LS, LT, LW, LY, LV, KA, KR, KN, KD, KC, KE, KQ, KG, KH, KI, KL, KK, KM, KF, KP, KS, KT, KW, KY, KV, MA, MR, MN, MD, MC, ME, MQ, MG, MH, MI, ML, MK, MM, MF, MP, MS, MT, MW, MY, MV, FA, FR, FN, FD, FC, FE, FQ, FG, FH, Fl, FL, FK, FM, FF, FP, 5 FS, FT, FW, FY, FV, PA, PR, PN, PD, PC, PE, PQ, PG, PH, PI, PL, PK, PM, PF, PP, PS, PT, PW, PY, PV, SA, SR, SN, SD, SC, SE, SQ, SG, SH, SI, SL, SK, SM, SF, SP, SS, ST, SW, SY, SV, TA, TR, TN, TD, TC, TE, TQ, TG, TH, TI, TL, TK, TM, TF, TP, TS, TT, TW, TY, TV, WA, WR, WN, WD, WC, WE, WQ, WG, WH, WI, WL, WK, WM, WF, WP, WS, WT, WW, WY, WV, YA, 10 YR, YN, YD, YC, YE, YQ, YG, YH, YI, YL, YK, YM, YF, YP, YS, YT, YW, YY, YV, VA, VR, VN, VD, VC, VE, VQ, VG, VH, VI, VL, VK, VM, VF, VP, VS, VT, VW, VY and VV. 2 3 Tripeptide residues are also useful as A2. When A is phosphonate, the sequence -X 4 -pro-X 5 - (where X 4 is any amino acid residue and X 5 is an amino 15 acid residue, a carboxyl ester of praline, or hydrogen) will be cleaved by luminal carboxypeptidase to yield X 4 with a free carboxyl, which in turn is expected to autocatalytically cleave the phosphonoamidate bond. The carboxy group of X 5 optionally is esterified with benzyl. Dipeptide or tripeptide species can be selected on the basis of known 20 transport properties and/or susceptibility to peptidases that can affect transport to intestinal mucosal or other cell types. Dipeptides and tripeptides lacking an a amino group are transport substrates for the peptide transporter found in brush border membrane of intestinal mucosal cells (Bai, J.P.F., "Pharm Res." 9:969 978 (1992). Transport competent peptides can thus be used to enhance 25 bioavailability of the amidate compounds. Di- or tripeptides having one or more amino acids in the D.configuration are also compatible with peptide transport and can be utilized in the amidate compounds of this invention. Amino acids in the D configuration can. be used to reduce the susceptibility of a di- or tripeptide to hydrolysis by proteases common to the brush. border such as aminopeptidase 30 N (EC 3.4.11.2). In addition, di- or tripeptides alternatively are selected on the basis of their relative resistance to hydrolysis by proteases found in the lumen of 35 WO 2008/005565 PCT/US2007/015664 the intestine. For example, tripeptides or polypeptides lacking asp and/or glu are poor substrates for aminopeptidase A (EC 3.4.11.7), di- or tripeptides lacking amino acid residues on the N-terminal side of hydrophobic amino acids (leu, tyr, phe, val, trp) are poor substrates for endopeptidase 24.11 (EC 3.4.24.11), and 5 peptides lacking a pro residue at the penultimate position at a free carboxyl terminus are poor substrates for carboxypeptidase P (EC 3.4.17). Similar considerations can also be applied to the selection of peptides that are either relatively resistant or relatively susceptible to hydrolysis by cytosolic, renal, hepatic, serum or other peptidases. Such poorly cleaved polypeptide amidates 10 are immunogens or are useful for bonding to proteins in order to prepare immunogens. HCV-Inhibitory Compounds The compounds of the invention include those with HCV-inhibitory activity as well as intermediate compounds that are useful for preparing the 15 active compounds. The term "HCV-inhibitory compound" includes those compounds that inhibit HCV. Typically, compounds of the invention have a molecular weight of from about 200 amu to about 10,000 amu; in a specific embodiment of the invention, compounds have a molecular weight of less than about 5000 amu; in another 20 specific embodiment of the invention, compounds have a molecular weight of less than about 2500 arnu; in another specific embodiment of the invention, compounds have a molecular weight of less than about 1000 amu; in another specific embodiment of the invention, compounds have a molecular weight of less than about 800 amu; in another specific embodiment of the invention, 25 compounds have a molecular weight of less than about 600 amu; and in another specific embodiment of the invention, compounds have a molecular weight of less than about 600 amu and a molecular weight of greater than about 400 amu. The compounds of the invention also typically have a logD(polarity) less than about 5. In one embodiment the invention provides compounds having a 30 logD less than about 4; in another one embodiment the invention provides compounds having a logD less than about 3; in another one embodiment the invention provides compounds having a logD greater than about -5; in another 36 WO 2008/005565 PCT/US2007/015664 one embodiment the invention provides compounds having a logD greater than about -3; and in another one embodiment the invention provides compounds having a logD greater than about 0 and less than about 3. Selected substituents within the compounds of the invention are present 5 to a recursive degree. In this context, "recursive substituent" means that a substituent may recite another instance of itself. Because of the recursive nature of such substituents, theoretically, a large number may be present in any given embodiment. For example, Rx contains a RY substituent. RY can be R 2 , which in turn can be R 3 . If R 3 is selected to be R 3 ", then a second instance of R' can be 10 selected. One of ordinary skill in the art of medicinal chemistry understands that the total number of such substituents is reasonably limited by the desired properties of the compound intended. Such properties include, by of example and not limitation, physical properties such as molecular weight, solubility or log P, application properties such as activity against the intended target, and 15 practical properties such as ease of synthesis. By way of example and not limitation, A 3 , A 2 and R' are all recursive substituents in certain embodiments. Typically, each of these may independently occur 20, 19, 18, 17,'16, 15, 14, 13, 12, 11, 10, 9, 8, 7, 6, 5, 4, 3, 2, 1, or 0, times in a given embodiment. More typically, each of these.may 20 independently occur 12 or fewer times in a given embodiment. Whenever a compound described herein is substituted with more than one of the same designated group, e.g., "R"' or "A 3 ", then it will be understood that the groups may be the same or different, i.e., each group is independently selected. Wavy lines indicate the site of covalent bond attachments to the adjoining groups, 25 moieties, or atoms. In one embodiment of the invention, the compound is in an isolated and purified form. Generally, the term "isolated and purified" means that the compound is substantially free from biological materials (e.g. blood, tissue, cells, etc.). In one specific embodiment of the invention, the term means that the 30 compound or conjugate of the invention is at least about 50 wt.% free from biological materials; in another specific embodiment, the term means that the compound or conjugate of the invention is at least about 75 wt.% free from 37 WO 2008/005565 PCT/US2007/015664 biological materials; in another specific embodiment, the term means that the compound or conjugate of the invention is at least about 90 wt.% free from biological materials; in another specific embodiment, the term means that the compound or conjugate of the invention is at least about 98 wt.% free from 5 biological materials; and in another embodiment, the term means that the compound or conjugate of the invention is at least about 99 wt.% free from biological materials. In another specific embodiment, the invention provides a compound or conjugate of the invention that has been synthetically prepared (e.g., ex vivo). 10 Cellular Accumulation In one embodiment, the invention provides compounds capable of accumulating in human PBMC (peripheral blood mononuclear cells). PBMC refer to blood cells having round lymphocytes and monocytes. Physiologically, PBMC are critical components of the mechanism against infection. PBMC may 15 be isolated from heparinized whole blood of normal healthy donors or buffy coats, by standard density gradient centrifugation and harvested from the interface, washed (e.g. phosphate-buffered saline) and stored in freezing medium. PBMC may be cultured in multi-well plates. At various times of culture, supernatant may be either removed for assessment, or cells may be 20 harvested and analyzed (Smith R. etal (2003) Blood 102(7):2532-2540). The compounds of this embodiment may further comprise a phosphonate or phosphonate prodrug. More typically, the phosphonate or phosphonate prodrug can have the structure A 3 as described herein. Stereoisomers 25 The compounds of the invention may have chiral centers, e.g., chiral carbon or phosphorus atoms. The compounds of the invention thus include racemic mixtures of all stereoisomers, including enantiomers, diastereomers, and atropisomers. In addition, the compounds of the invention include enriched or resolved optical isomers at any or all asymmetric, chiral atoms. In other words, 30 the chiral centers apparent from the depictions are provided as the chiral isomers or racemic mixtures. Both racemic and diastereomeric mixtures, as well as the 38 WO 2008/005565 PCTIUS2007/015664 individual optical isomers isolated or synthesized, substantially free of their enantiomeric or diastereomeric partners, are all within the scope of the invention. The racemic mixtures are separated into their individual, substantially optically pure isomers through well-known techniques such as, for example, the 5 separation of diastereomeric salts formed with optically active adjuncts, e.g., acids or bases followed by conversion back to the optically active substances. In most instances, the desired optical isomer is synthesized by means of stereospecific reactions, beginning with the appropriate stereoisomer of the desired starting material. 10 The compounds of the invention can also exist as tautomeric isomers in certain cases. Although only one delocalized resonance structure may be depicted, all such forms are contemplated within the scope of the invention. For example, ene-amine tautomers can exist for purine, pyrimidine, imidazole, guanidine, amidine, and tetrazole systems and all their possible tautomeric forms 15 are within the scope of the invention. Salts and Hydrates Examples of physiologically acceptable salts of the compounds of the invention include salts derived from an appropriate base, such as an alkali metal (for example, sodium), an alkaline earth (for example, magnesium), ammonium 20 and NX4 (wherein X is C-C 4 alkyl). Physiologically acceptable salts of a hydrogen atom or an amino group include salts of organic carboxylic acids such as acetic, benzoic, lactic, fumnaric, tartaric, maleic, malonic, malic, isethionic, lactobionic and succinic acids; organic sulfonic acids, such as methanesulfonic, ethanestilfonic, benzenesulfonic and p-toluenesulfonic acids; and inorganic 25 acids, such as hydrochloric, sulfuric, phosphoric and sulfamic acids. Physiologically acceptable salts of a compound of an hydroxy group include the anion of said compound in combination with a suitable cation such as Na and NX4* (wherein X is independently selected from H or a CI-C4'alkyl group). For therapeutic use, salts of active ingredients of the compounds of the 30 invention will typically be physiologically acceptable, i.e. they will be salts derived from a physiologically acceptable acid or base. However, salts of acids 39 WO 2008/005565 PCTIUS2007/015664 or bases which are not physiologically acceptable may also find use, for example, in the preparation or purification of a physiologically acceptable compound. All salts, whether or not derived form a physiologically acceptable acid or base, are within the scope of the present invention. 5 Metal salts typically are prepared by reacting the metal hydroxide with a compound of this invention. Examples of metal salts which are prepared in this way are salts containing Li+, Na+, and K+. A less soluble metal salt can be precipitated from the solution of a more soluble salt by addition of the suitable metal compound. 10 In addition, salts may be formed from acid addition of certain organic and inorganic acids, e.g., HCI, HBr, H 2 SO4, H3PO4 or organic sulfonic acids, to basic centers, typically amines, or to acidic groups. Finally, it is. to be understood that the compositions herein comprise compounds of the invention in their un-ionized, as well as zwitterionic form, and combinations with 15 stoichiometric amounts of water as in hydrates. Also included within the scope of this invention are the salts of the parental compounds with one or more amino acids. Any of the natural or unnatural amino acids are suitable, especially the naturally-occurring amino acids found as protein components, although the amino acid typically is one 20 bearing a side chain with a basic or acidic group, e.g., lysine, arginine or glutamic acid, or a neutral group such as glycine, serine, threonine, alanine, isoleucine, or leucine. Methods of Inhibition of HCV Another aspect of the invention relates to methods of inhibiting the 25 activity of HCV comprising the step of treating a sample suspected of containing HCV with a compound or composition of the invention. Compounds of the invention may act as inhibitors of HCV, as intermediates for such inhibitors or have other utilities as described below. The inhibitors will generally bind to locations on the surface or in a cavity of the 30 liver. Compounds binding in the liver may bind with varying degrees of reversibility. Those compounds binding substantially irreversibly are ideal 40 WO 2008/005565 PCT/US2007/015664 candidates for use in this method of the invention. Once labeled, the substantially irreversibly binding compounds are useful as probes for the detection of HCV. Accordingly, the invention relates to methods of detecting NS3 in a sample suspected of containing HCV comprising the steps of: treating a 5 sample suspected'of containing HCV with a composition comprising a compound of the invention bound to a label; and observing the effect of the sample on the activity of the label. Suitable labels are well known in the * diagnostics field and include stable free radicals, fluorophores, radioisotopes, enzymes, chemiluminescent groups and chromogens. The compounds herein are 10 labeled in conventional fashion using functional groups such as hydroxyl or amino. In one embodiment the invention provides a compound of formula (I) that comprises or that is bound or linked to one or more detectable labels. Within the context of the invention samples suspected of containing HCV include natural or man-made materials such as living organisms; tissue or 15 cell cultures; biological samples such as biological material samples (blood, serum, urine, cerebrospinal fluid, tears, sputum, saliva, tissue samples, and the like); laboratory samples; food, water, or air samples; bioproduct samples such as extracts of cells, particularly recombinant cells synthesizing a desired glycoprotein; and the like. Typically the sample will be suspected of containing 20 HCV. Samples can be contained in any medium including water and organic solvent/water mixtures. Samples include living organisms such as humans, and man made materials such as cell cultures. The treating step of the invention comprises adding the comound of the invention to the sample or it comprises adding a precursor of the composition to .25 'the sample. The addition step comprises any method of administration as described above. If desired, the activity of HCV after application of the compound can be observed by any method including direct and indirect methods of detecting HCV activity. Quantitative, qualitative, and semiquantitative methods of determining 30 HCV activity are all contemplated. Typically one of the screening methods described above are applied, however, any other method such as observation of the physiological properties of a living organism are also applicable. 41 WO 2008/005565 PCTIUS2007/015664 Many organisms contain HCV. The compounds of this invention are useful in the treatment or prophylaxis of conditions associated with HCV activation in animals or in man. However, in screening compounds capable of inhibiting HCV it should 5 be kept in mind that the results of enzyme assays may not always correlate with cell culture assays. Thus, a cell based assay should typically be the primary screening tool. Screens for HCV Inhibitors Compounds of the invention are screened for inhibitory activity against 10 HCV by any of the conventional techniques for evaluating enzyme activity. Within the context of the invention, typically compounds are first screened for inhibition of HCV in vitro and compounds showing inhibitory activity are then screened for activity in vivo. Compounds having in vitro Ki (inhibitory constants) of less then about 5 X 10-6 M, typically less than about I X 10-7 M 15 and preferably less than about 5 X I 0-8 M are preferred for in vivo use. Useful in vitro screens have been described in detail. Pharmaceutical Formulations The compounds of this invention are formulated with conventional carriers and excipients, which will be selected in accord with ordinary practice. 20 Tablets will contain excipients, glidants, fillers, binders and the.like. Aqueous formulations are prepared in sterile form, and when intended for delivery by other than oral administration generally will be isotonic. All formulations will optionally contain excipients such as those set forth in the Handbook of Pharmaceutical Excipients (1986). Excipients include ascorbic acid and other 25 antioxidants, chelating agents such as EDTA, carbohydrates such as dextrin, hydroxyalkylcellulose, hydroxyalkylmethylcellulose, stearic acid and the like. The pH of the formulations ranges from about 3 to about 11, but is ordinarily about 7 to 10. While it is possible for the active ingredients to be administered alone it 30 may be preferable to present them as pharmaceutical formulations. The formulations, both for veterinary and for human use, of the invention comprise at 42 WO 2008/005565 PCT/US2007/015664 least one active ingredient, as above defined, together with one or more acceptable carriers therefor and optionally other therapeutic ingredients. The carrier(s) must be "acceptable" in the sense of being compatible with the other ingredients of the formulation and physiologically innocuous to the recipient 5 thereof. The formulations include those suitable for the foregoingadministration routes. The formulations may conveniently be presented in unit dosage form and may be prepared by any of the methods well known in the art of pharmacy. Techniques and formulations generally are found in Remington's Pharmaceutical 10 Sciences (Mack Publishing Co., Easton, PA). Such methods include the step of bringing into association the active ingredient with the carrier which constitutes one or more accessory ingredients. In general the formulations are prepared by uniformly and intimately bringing into association the active ingredient with liquid carriers or finely divided solid carriers or both, and then, if necessary, 15 shaping the product. Formulations of the present invention suitable for oral administration may be presented as discrete units such as capsules, cachets or tablets each containing a predetermined amount of the active ingredient; as a powder or granules; as a solution or a suspension in an aqueous or non-aqueous liquid; or 20 as an oil-in-water liquid emulsion or a water-in-oil liquid emulsion. The active ingredient may also be administered as a bolus, electuary or paste. A tablet is made by compression or molding, optionally with one or more accessory ingredients. Compressed tablets may be prepared by compressing in a suitable machine the active ingredient in a free-flowing form such as a powder or 25 granules, optionally rixed with a binder, lubricant, inert diluent, preservative, surface active or dispersing agent. Molded tablets may be made by molding in a suitable machine a mixture of the powdered active ingredient moistened with an inert liquid diluent. The tablets may optionally be coated or scored and optionally are formulated so as to provide slow or controlled release of the active 30 ingredient therefrom. For administration to the eye or other external tissues e.g., mouth and skin, the formulations are preferably applied as a topical ointment or cream 43 WO 2008/005565 PCT/US2007/015664 containing the active ingredient(s) in an amount of, for example, 0.075 to 20% w/w (including active ingredient(s) in a range between 0.1% and 20% in increments of 0.1% w/w such as 0.6% w/w, 0.7% w/w, etc.), preferably 0.2 to 15% w/w and most preferably 0.5 to 10% w/w. When formulated in an 5 ointment, the active ingredients may be employed with either a paraffinic or a water-miscible ointment base. Alternatively, the active ingredients may be formulated in a cream with an oil-in-water cream base. If desired, the aqueous phase of the cream base may include, for example, at least 30% w/w of a polyhydric alcohol, i.e. an alcohol having two or 10 more hydroxyl groups such as propylene glycol, butane 1,3-diol, mannitol, sorbitol, glycerol and polyethylene glycol (including PEG 400) and mixtures thereof. The topical formulations may desirably include a compound which enhances absorption or penetration of the active ingredient through the skin or other affected areas. Examples of such dermal penetration enhancers include 15 dimethyl sulphoxide and related analogs. The oily phase of the emulsions of this invention may be constituted from known ingredients in a known manner. While the phase may comprise merely an emulsifier (otherwise known as an emulgent), it desirably comprises a mixture of at least one emulsifier with a fat or an oil or with both a fat and an oil. 20 Preferably, a hydiophilic emulsifier is included together with a lipophilic emulsifier which acts as a stabilizer. It is also preferred to include both an oil and a fat. Together, the emulsifier(s) with or without stabilizer(s) make up the so-called emulsifying wax, and the wax together with the oil and fat make up the so-called emulsifying ointment base which forms the oily dispersed phase of the 25 cream formulations. Emulgents and emulsion stabilizers suitable for use in the formulation of the invention include Tween® 60, Span® 80, cetostearyl alcohol, benzyl alcohol, myristyl alcohol, glyceryl mono-stearate and sodium lauryl sulfate. The choice of suitable oils or fats for the formulation is based on 30 achieving the desired cosmetic properties. The cream should preferably be a non-greasy, non-staining and washable product with suitable consistency to avoid leakage from tubes or other containers. Straight or branched chain, mono 44 WO 2008/005565 PCT/US2007/015664 or dibasic alkyl esters such as di-isoadipate, isocetyl stearate, propylene glycol. diester of coconut fatty acids, isopropyl myristate, decyl oleate, isopropyl palmitate, butyl stearate, 2-ethylhexyl palmitate or a blend of branched chain esters known as Crodamol CAP may be used, the last three being preferred 5 esters. These may be used.alone or in combination depending on the properties required. Alternatively, high melting point lipids such as white soft paraffin and/or liquid paraffin or other mineral oils are used. Pharmaceutical formulations according to the present invention comprise one or more compounds of the invention together with one or more 10 pharmaceutically acceptable carriers or excipients and optionally other therapeutic agents. Pharmaceutical formulations containing the active ingredient may be in any form suitable for the intended method of administration. When used for oral use for example, tablets, troches, lozenges, aqueous or oil suspensions, dispersible powders or granules, emulsions, hard or soft capsules, 15 syrups or elixirs may be prepared. Compositions intended for oral use may be prepared according to any method known to the art for the manufacture of pharmaceutical compositions and such compositions may contain one or more agents including sweetening agents, flavoring agents, coloring agents and preserving agents, in order to provide a palatable preparation. Tablets containing 20 the active ingredient in admixture with non-toxic pharmaceutically acceptable excipients which are suitable for manufacture of tablets are acceptable. These excipients may be, for example, inert diluents, such as calcium or sodium carbonate, lactose, lactose monohydrafe, croscarmellose sodium, povidone, calcium or sodium phosphate; granulating and disintegrating agents, such as 25 maize starch, or alginic acid; binding agents, such as cellulose, microcrystalline cellulose, starch, gelatin or acacia; and lubricating agents, such as magnesium stearate, stearic acid or talc. Tablets may be uncoated or may be coated by known techniques including microencapsulation to delay disintegration and adsorption in the gastrointestinal tract and thereby provide a sustained action 30 over a longer period. For example, a time delay material such as glyceryl monostearate or glyceryl distearate alone or with a wax may be employed. 45 WO 2008/005565 PCT/US2007/015664 Formulations fot oral use may be also presented as hard gelatin capsules where the active ingredient is mixed with an inert solid diluent, for example calcium phosphate or kaolin, or as soft gelatin capsules wherein the active ingredient is mixed with water or an oil medium, such as peanut oil, liquid 5 paraffin or olive oil. Aqueous suspensions of the invention contain the active materials in admixture with excipients suitable for the manufacture of aqueous suspensions. Such excipients include a suspending agent, such as sodium carboxymethylcellulose, methylcellulose, hydroxypropyl methylcelluose, 10 sodium alginate, polyvinylpyrrolidone, gum tragacanth and gum acacia, and dispersing or wetting agents such as a naturally occurring phosphatide (e.g., lecithin), a condensation product of an alkylene oxide with a fatty acid (e.g., polyoxyethylene stearate), a condensation product of ethylene oxide with a long chain aliphatic alcohol (e.g., heptadecaethyleneoxycetanol), a condensation 15 product of ethylene oxide with a partial ester derived from a fatty acid and a hexitol anhydride (e.g., polyoxyethylene sorbitan monooleate). The aqueous suspension may also contain one or more preservatives such as ethyl or n-propyl p-hydroxy-benzoate,-one or more coloring agents, one or more flavoring agents and one or more sweetening agents, such as sucrose or saccharin. 20 Oil suspensions may be formulated by suspending the active ingredient in a vegetable oil, such as arachis oil, olive oil, sesame oil or coconut oil, or in a mineral oil such as liquid paraffin. The oral suspensions may contain a thickening agent, such as beeswax, hard paraffin or.cetyl alcohol. Sweetening agents, such as those set forth above, and flavoring agents may be added to 25 provide a palatable oral preparation. These compositions may be preserved by the addition of an antioxidant such as ascorbic acid. Dispersible powders and granules of the invention suitable for preparation of an aqueous suspension by the addition of water provide the active ingredient in admixture with a dispersing or wetting agent, a suspending agent, 30 and one or more preservatives. Suitable dispersing or wetting agents and suspending agents are exemplified by those disclosed above. Additional 46 WO 2008/005565 PCT/US2007/015664 excipients, for'example sweetening, flavoring and coloring agents, may also be present. The pharmaceutical compositions of the invention may also be in the form of oil-in-water emulsions. The oily phase may be a vegetable oil, such as 5 olive oil or arachis oil, a mineral oil, such as liquid paraffin, or a mixture of these. Suitable emulsifying agents include naturally-occurring gums, such as gum acacia and gum tragacanth, naturally occurring phosphatides, such as soybean lecithin, esters or partial esters derived from fatty acids and hexitol anhydrides, such as sorbitan monooleate, and condensation products of these 10 partial esters with ethylene oxide, such as polyoxyethylene sorbitan monooleate. The emulsion may also contain sweetening and flavoring agents. Syrups and elixirs may be formulated with sweetening agents, such as glycerol, sorbitol or sucrose. Such formulations may also contain a demulcent, a preservative, a flavoring or a coloring agent. 15 The pharmaceutical compositions of the invention may be in the form of a sterile injectable preparation, such as a sterile injectable aqueous or oleaginous suspension. 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 20 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 25 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 30 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 47 WO 2008/005565 PCTIUS2007/015664 and convenient amount of carrier material which may vary from about 5 to about 95% of the total compositions (weight:weight). The pharmaceutical composition can be prepared to provide easily measurable amounts for administration. For example, an aqueous solution intended for intravenous infusion may contain 5 from about 3 to 500 pig 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. Formulations suitable for administration to the eye include eye drops wherein the active ingredient is dissolved or suspended in a suitable carrier, especially an aqueous solvent for the active ingredient. The active ingredient is 10 preferably present in such formulations in a concentration of 0.5 to 20%, advantageously 0.5 to 10% particularly about 1.5% w/w. Formulations suitable for topical administration in the mouth include lozenges comprising the active ingredient in a flavored basis, usually sucrose and acacia or tragacanth; pastilles comprising the active ingredient in an inert 15 basis such as gelatin and glycerin, or sucrose and acacia; and mouthwashes comprising the active ingredient in a suitable liquid carrier. Formulations for rectal administration may be presented as a suppository with a suitable base comprising for example cocoa butter or a salicylate. Formulations suitable for intrapulmonary or nasal administration have a 20 particle size for example in the range of 0.1 to 500 microns (including particle sizes in a range between 0.1 and 500 microns in increments microns such as 0.5, 1, 30 microns, 35 microns, etc.), which is administered by rapid inhalation through the nasal passage or by inhalation through the mouth so as to reach the alveolar sacs. Suitable formulations include aqueous or oily solutions of the 25 active ingredient. Formulations suitable for aerosol or dry powder administration may be prepared according to conventional methods and may be - delivered with other therapeutic agents such as compounds heretofore used in the treatment or prophylaxis of conditions associated with HCV activity. Formulations suitable for vaginal administration may be presented as 30 pessaries, tampons, creams, gels, pastes, foams or spray formulations containing in addition to the active ingredient such carriers as are known in the art to be appropriate. 48 WO 2008/005565 PCT/US2007/015664 Formulations suitable for parenteral administration include aqueous and non-aqueous sterile injection solutions which may contain anti-oxidants, buffers, bacteriostats and solutes which render the formulation isotonic with the blood of the intended recipient; and aqueous and non-aqueous sterile suspensions which 5 may include suspending agents and thickening agents. The formulations are presented in unit-dose or multi-dose containers, for example sealed ampoules and vials, and may be stored in a freeze-dried lyophilizedd) condition requiring only the addition of the sterile liquid carrier, for example water for injection, immediately prior to use. Extemporaneous 10 injection solutions and suspensions are prepared from sterile powders, granules and tablets of the kind previously described. Preferred unit dosage formulations are those containing a daily dose or unit daily sub-dose, as herein above recited, or an appropriate fraction thereof, of the active ingredient. It should be understood that in addition to the ingredients particularly 15 mentioned above the formulations of this invention may include other agents conventional in the art having regard to the type of formulation in question, for example those suitable for oral administration may include flavoring agents. The invention further provides veterinary compositions comprising at least one active ingredient as above defined together with a veterinary carrier 20 therefor. Veterinary carriers are materials useful for the purpose of administering the composition and may be solid, liquid or gaseous materials which are otherwise inert or acceptable in the veterinary art and are compatible with the active ingredient. These veterinary compositions may be administered orally, 25 parenterally or by any other desired route. Compounds of the invention can also be formulated to provide controlled release of the active ingredient to allow less frequent dosing or to improve the pharmacokinetic or toxicity profile of the active ingredient. Accordingly, the invention also provided compositions comprising one or more compounds of the 30 invention formulated for sustained or controlled release. Effective dose of active ingredient depends at least on the nature of the condition being treated, toxicity, whether the compound is being used 49 WO 2008/005565 PCTUS2007/015664 prophylactically (lower doses), the method of delivery, and the pharmaceutical formulation, and will be determined by the clinician using conventional dose escalation studies. It can be expected to be from about 0.000 1 to about 100 mg/kg body weight per day. Typically, from about 0.01 to about 10 mg/kg body 5 weight per day. More typically, from about .01 to about 5 mg/kg body weight per day. More typically, from about .05 to about 0.5 mg/kg body weight per day. For example, the daily candidate dose for an adult human of approximately 70 kg body weight will range from 1 mg to 1000 mg, preferably between 5 mg and 500 mg, and may take the form of single or multiple doses. 10 Routes of Administration One or more compounds of the invention (herein referred to as the active ingredients) are administered by any route appropriate to the condition to be treated. Suitable routes include oral, rectal, nasal, topical (including buccal and sublingual), vaginal and parenteral (including subcutaneous, intramuscular, 15 intravenous, intradermal, intrathecal and epidural), and the like. It will be appreciated that the preferred route may vary with for example the condition of the recipient. An advantage of the compounds of this invention is that they are orally bioavailable and can be dosed orally. Combination Therapy 20 . Active ingredients of the invention can also be used in combination with other active ingredients. Such combinations are selected based on the condition to be treated, cross-reactivities of ingredients and pharmaco-properties of the combination. It is also possible to combine any compound of the invention with one or 25 more other active ingredients in a unitary dosage form for simultaneous or sequential administration to a patient. The combination therapy may be administered as a simultaneous or sequential regimen. When administered sequentially, the combination may be administered in two or more administrations. 30 The combination therapy may provide "synergy" and "synergistic effect", i.e. the effect achieved when the active ingredients used together is greater than 50 WO 2008/005565 PCT/US2007/015664 the sum of the effects that results from using the compounds separately. A synergistic effect may be attained when the active ingredients are: (1) co formulated and administered or delivered simultaneously in a combined formulation; (2) delivered by alternation or in parallel as separate formulations; 5 or (3) by some other regimen. When delivered in alternation therapy, a 'synergistic effect may be attained when the compounds are administered or delivered sequentially, e.g., in separate tablets, pills or capsules, or by different injections in separate syringes. In general, during alternation therapy, an effective dosage of each active ingredient is administered sequentially, i.e. 10 serially, whereas in combination therapy, effective dosages of two or more active ingredients are administered together. Metabolites of the Compounds of the Invention Also falling within the scope of this invention are the in vivo metabolic products of the compounds described herein. Such products may result for 15 example from the oxidation, reduction, hydrolysis, amidation, esterification and the like of the administered compound, primarily due to enzymatic processes. Accordingly, the invention includes compounds produced by a process comprising contacting a compound of this invention with a mammal for a period of time sufficient to yield a metabolic product thereof. Such products typically 20 are identified by preparing a radiolabelled (e.g., C1 4 or H 3 ) compound of the invention, administering it parenterally in a detectable dose (e.g., greater than about 0.5 mg/kg) to an animal such as rat, mouse, guinea pig, monkey, or to man, allowing sufficient time for metabolism to occur (typically about 30 seconds-to 30 hours) and isolating its conversion products from the urine, blood 25 or other biological samples. These products are easily isolated since they are labeled (others are isolated by the use of antibodies capable of binding epitopes surviving in the metabolite). The metabolite structures are determined in conventional fashion, e.g., by MS or NMR analysis. In general, analysis of metabolites is done in the same way as conventional drug metabolism studies 30 well-known to those skilled in the art. The conversion products, so long as they are not otherwise found in vivo, are useful in diagnostic assays for therapeutic 51 WO 2008/005565 PCT/US2007/015664 dosing of the compounds of the invention even if they possess no HCV inhibitory activity of their own. Methods for determining stability of compounds in surrogate gastrointestinal secretions are known. Compounds are defined herein as stable 5 in the gastrointestinal tract where less than about 50 mole percent of the protected groups are deprotected in surrogate intestinal or gastric juice upon incubation for 1 hour at 37 *C. Simply because the compounds are stable to the gastrointestinal tract does not mean that they cannot be hydrolyzed in vivo. The phosphonate prodrugs of the invention typically will be stable in the digestive 10 system but are substantially hydrolyzed to the parental drug in the digestive lumen, liver or other metabolic organ, or within cells in general. Exemplary Methods of Making the CopQunds of the Invention. The invention also relates to methods of making the compositions of the invention. The compositions are prepared by any of the applicable techniques of 15 organic synthesis. Many such techniques are well known in the art. However, many of the known techniques are elaborated in Compendium of Organig Synthetic Methods (John Wiley & Sons, New York), Vol. 1, Ian T. Harrison and Shuyen Harrison, 1971; Vol. 2, Ian T. Harrison and Shuyen Harrison, 1974; Vol. 3, Louis S. Hegedus and Leroy Wade, 1977; Vol. 4, Leroy G. Wade, jr., 1980; 20 Vol. 5, Leroy G. Wade, Jr., 1984; and Vol. 6, Michael B. Smith; as well as March, J., Advanced Organic Chemistry, Third Edition, (John Wiley & Sons, New York, 1985), Comprehensive Organic Synthesis. Selectivity. Strategy & Efficiency in Modem Organic Chemistry. In 9 Volumes Barry M. Trost, Editor-in-Chief (Pergamon Press, New York, 1993 printing). Other methods 25 suitable for preparing compounds of the invention are described in International Patent Application Publication Number WO 2006/020276. A number of exemplary methods for the preparation of the compositions of the invention are provided below. These methods are intended to illustrate the nature of such preparations and are not intended to limit the scope of applicable 30 methods. Generally, the reaction conditions such as temperature, reaction time, solvents, work-up procedures, and the like, will be those common in the art for 52 WO 2008/005565 PCT/US2007/015664 the particular reaction to be performed. The cited reference material, together with material cited therein, contains detailed descriptions of such conditions. Typically the temperatures will be -100*C to 200*C, solvents will be aprotic or protic, and reaction times will be 10 seconds to 10 days. Work-up typically 5 consists of quenching any unreacted reagents followed by partition between a water/organic layer system (extraction) and separating the layer containing the product. Oxidation and reduction reactions are typically carried out at temperatures near room temperature (about 20 *C), although for metal hydride 10 reductions frequently the temperature is reduced to 0 *C to -100 *C, solvents are 'typically aprotic for reductions and may be either protic or aprotic for oxidations. Reaction times are adjusted to achieve desired conversions. Condensation reactions are typically carried out at temperatures near room temperature, although for non-equilibrating, kinetically controlled 15 condensations reduced temperatures (0 *C to -100 *C) are also common. Solvents can be either protic (common in equilibrating reactions) or aprotic (common in kinetical.ly controlled reactions). Standard synthetic techniques such as azeotropic removal of reaction by products and use of anhydrous reaction conditions (e.g., inert gas environments) 20 are common in the art and will be applied when applicable. The terms "treated", "treating", "treatment", and the like, when used in connection with a chemical synthetic operation, mean contacting, mixing, reacting, allowing to react, bringing into contact, and other terms common in the art for indicating that one or more chemical entities is treated in such a manner 25 as to convert it to one or more other chemical.entities. This mans that "treating compound one with compound two" is synonymous with "allowing compound one to react with compound two", "contacting compound one with compound two", "reacting compound one with compound two", and other expressions common in the art of organic synthesis for reasonably indicating that compound 30 one was "treated", "reacted", "allowed to react", etc., with compound two. For example, treating indicates the reasonable and usual manner in which organic chemicals are allowed to react. Normal concentrations (0.01M to 10M, typically 53 WO 2008/005565 PCT/US2007/015664 0.IM to 1M), temperatures (-100 *C to 250 *C, typically -78 *C to 150 *C, more typically -78 *C to 100 *C, still more typically 0 *C to 100 *C), reaction vessels (typically glass, plastic, metal), solvents, pressures, atmospheres (typically air for oxygen and water insensitive reactions or nitrogen or argon for oxygen or 5 water sensitive), etc., are intended unless otherwise indicated. The knowledge of similar reactions known in the art of organic synthesis are used in selecting the conditions and apparatus for "treating" in a given process. In particular, one of ordinary skill in the art of organic synthesis selects conditions and apparatus reasonably expected to successfully carry out the chemical reactions of the 10 described processes based on the knowledge in the art. Modifications of each of the exemplary schemes and in the examples (hereafter "exemplary schemes") leads to various analogs of the specific exemplary materials produce. The above-cited citations describing suitable methods of organic synthesis are applicable to such modifications. 15 In each of the exemplary schemes it may be advantageous to separate reaction products from one another and/or from starting materials. The desired products of each step or series of steps is separated and/or purified (hereinafter separated) to the desired degree of homogeneity by the techniques common in the art. Typically such separations involve multiphase extraction, crystallization 20 from a solvent or solvent mixture, distillation, sublimation, or chromatography. Chromatography can involve any number of methods including, for example: reverse-phase and normal phase; size exclusion; ion exchange; high, medium, and low pressure liquid chromatography methods and apparatus; small scale analytical; simulated moving bed (SMB) and preparative thin or thick layer 25 chromatography, as well as techniques of small scale thin layer and flash chromatography. Another class of separation methods involves treatment of a mixture with a reagent selected to bind to or render otherwise separable a desired product, unreacted starting material, reaction by product, or the like. Such reagents 30 include adsorbents or absorbents such as activated carbon, molecular sieves, ion exchange media, or the like. Alternatively, the reagents can be acids in the case of a basic material, bases in the case of an acidic material, binding reagents such 54 WO 2008/005565 PCT/US2007/015664 as antibodies, binding proteins, selective chelators such as crown ethers, liquid/liquid ion extraction reagents (LIX), or the like. Selection of appropriate methods of separation depends on the nature of the materials involved. For example, boiling point, and molecular weight in 5 distillation and sublimation, presence or absence of polar functional groups in chromatography, stability of materials in acidic and basic media in multiphase extraction, and the like. One skilled in the art will apply techniques most likely to achieve the desired separation. A single stereoisomer, e.g., an enantiomer, substantially free of its 10 stereoisomer may be obtained by resolution of the racemic mixture using a method such as formation of diastereomers using optically active resolving agents (Stereochemistry of Carbon Compounds (1962) by E. L. Eliel, McGraw Hill; Lochmuller, C. H., (1975).J. Chromatogr., 113:(3) 283-302). Racemic mixtures of chiral compounds of the invention can be separated and isolated by 15 any suitable method, including: (1) formation of ionic, diastereomeric salts with chiral compounds and separation by fractional crystallization or other methods, (2) formation of diastereomeric compounds with chiral derivatizing reagents, separation of the diastereomers, and conversion to the pure stereoisomers, and (3) separation of the substantially pure or enriched stereoisomers directly under 20 chiral conditions. Under method (1), diastereomeric salts can be formed by reaction of enantiomerically pure chiral bases such as brucine, quinine, ephedrine, strychnine, cc-methyl-p-phenylethylamine (amphetamine), and the like with asymmetric compounds bearing acidic functionality, such as carboxylic acid and 25 sulfonic acid. The diastereomeric salts may be induced to separate by fractional crystallization or ionic chromatography. For separation of the optical isomers of amino compounds, addition of chiral carboxylic or sulfonic acids, such as camphorsulfonic acid, tartaric acid, mandelic acid, or lactic acid can result in formation of the diastereomeric salts. 30 Alternatively, by method (2), the substrate to be resolved is reacted with one enantiomer of a chiral compound to form a diastereomeric pair (Eliel, E. and Wilen, S. (1994) Stereochemistry of Organic Compounds John Wiley & Sons, 55 WO 2008/005565 PCT/US2007/015664 Inc., p. 322). Diastereomeric compounds can be formed by reacting asymmetric compounds with enantiomerically pure chiral derivatizing reagents, such as menthyl derivatives, followed by separation of the diastereomers and hydrolysis to yield the free, enantiomerically enriched xanthene. A method of determining 5 optical purity involves making chiral esters, such as a menthyl ester, e.g., (-) menthyl chloroformate in the presence of base, or Mosher ester, ot-methoxy-at (trifluoromethyl)phenyl acetate (Jacob III. (1982) J. Org. Chem. 47:4165), of the -racemic mixture, and analyzing the NMR spectrum for the presence of the two atropisomeric diastereomers. Stable diastereomers of atropisomeric compounds 10 can be separated and isolated by normal- and reverse-phase chromatography following methods for separation of atropisomeric naphthyl-isoquinolines (Hoye, T., WO 96/15111). By method (3), a racemic mixture of two enantiomers can be separated by chromatography using a chiral stationary phase (Chiral Liquid Chromatography (1989) W. J. Lough, Ed. Chapman and Hall, 15 New York; Okamoto, (1990) J. of Chromatogr. 513:375-378). Enriched or purified enantiomers can be distinguished by methods used to distinguish other chiral molecules with asymmetric carbon atoms, such as optical rotation and circular dichroism.

The resulting mixture was stirred for 18 hr after which another portion of cesium hydroxide monohydrate (82 g, 490 mmol) was added. The resulting mixture was stirred for 24 5 hr. The salts were then filtered off through a celite 521 pad and the filtrate was allowed to stir with I N aq. HCI at rt for 3 h. The resulting mixture was filtered through another celite 521 pad and the two phases of the filtrate were separated. The organic fraction was extracted with I N aq. HCI (250 mL x 1). The aqueous 10 fractions were washed with dichloromethane (250 mL x 1) and the combined aq. fractions were stirred with ethyl acetate (500 mL) while 84 g (1 mol) of NaHCO 3 was added cautiously, followed by excess NaCl until saturated. After the resulting mixture was filtered through a celite 521 pad to remove excess NaCl and some 15 black tar, the two layers were separated and the aqueous fraction was extracted further with ethyl acetate (250 mL x 2). The organic extracts were washed with a saturated NaCl solution (250 mL x 1), combined, dried (MgSO 4 ), and concentrated to obtain -16.5-17 g of the crude amine. 20 The crude amine was partially purified by column chromatography using 165-170 g of silica gel by eluting with ethyl acetate (100%, - 500 mL), followed by 5% methanol in ethyl acetate (-1200 mL). The product containing fractions were pooled and concentrated, which resulted 11.5 -- 12 g ofpartially purified 25 amine. To this amine was added a solution of 18.8 - 19.6 g (1 mole eq.) of dibenzoyl-L-tartaric acid in 151.5 - 158 mL of acetonitrile (5 times the amount of the salt). The mixture was heated until it became a solution and cooled slowly at rt to obtain solids. After 30 overnight, the solids were collected by filtration and washed with acetonitrile. The solids were recrystallized from the same amount of acetonitrile again at rt to afford 11.5 g of optically pure salt. 85 WO 2008/005565 PCT/US2007/015664 'H NMR (300 MHz, CD 3 OD) 8 8.14 (br, 2H), 8.11 (d, J = 1.2 Hz, 2H), 7.64 (tt, J = 7.5 and 1.2 Hz, 2H), 7.51 (br t, J = 7.5 Hz, 4H), 5.94 (s, 2H), 5.82 (dt, J = 17.1 and 9.9 Hz, 1H), 5.32 (dd, J = 17.1 and 1.2 Hz, 1H), 5.13 (dd, J = 10.5 and 1.2 Hz, IH), 4.11 - 4.26 5 (m, 4H), 2.11 (m, 1H), 1.33 - 1.47 (m, 2H), 1.37 (dt, J = 10.2 and 7.2 Hz, 6H); 31 P NMR (121.4 MHz, CD 3 OD) 8 22.55.
