BACKGROUND tis 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 effectiveness, toxicity and other side effects have limited their usefulness. tors of hepatitis C virus (HCV) are useful to limit the establishment and ssion of infection by HCV as well as in diagnostic assays for HCV.

There is a need for new HCV therapeutic agents. In particular, there is a need for HCV therapeutic agents that have broad activity against HCV genotypes (e.g. genotypes 1s, 1b, 2a, 3a, 4a).

There is also a particular need for agents that are less susceptible to viral resistance. Resistance mutations to inhibitors have been described for HCV NS5A for genotypes 1a and 1b in Antimicrobial Agents and Chemotherapy, September 2010, Volume 54, p. 3641-3650.

Parker, Ed., McGraw-Hill Dictionary of Chemical Terms (1984) McGraw-Hill Book Company, New York; and Eliel, E. and Wilen, S., Stereochemistry of 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 (s). The prefixes d and l or (+) and (-) are employed to ate 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 r. A specific stereoisomer may also be referred to as an enantiomer, and a mixture of such s is often called an omeric mixture. A 50:50 mixture of enantiomers is ed to as a racemic mixture or a racemate, which may occur where there has been no stereoselection or stereospecificity in a chemical reaction or s. The terms "racemic mixture" and "racemate" refer to an equimolar mixture of two enantiomeric species, devoid of l activity. The disclosure includes all stereoisomers of the compounds bed herein.

Prodrugs The term "prodrug" as used herein refers to any compound that when administered to a biological system generates a nd of the disclosure that inhibits HCV activity ("the active inhibitory compound"). The compound may be formed from the prodrug as a result of: (i) spontaneous al reaction(s), (ii) enzyme catalyzed chemical reaction(s), (iii) photolysis, and/or (iv) metabolic chemical reaction(s).

"Prodrug moiety" refers to a labile functional group which separates from the active inhibitory compound during metabolism, systemically, inside a cell, by hydrolysis, enzymatic cleavage, or by some other process aard, 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 prodrug compounds of the disclosure include, but are not limited to, amidases, esterases, microbial s, phospholipases, cholinesterases, and phosphases. Prodrug moieties can serve to enhance solubility, absorption and ilicity to optimize drug ry, bioavailability and efficacy. A prodrug moiety may include an active metabolite or drug itself.

Exemplary prodrug moieties include the hydrolytically sensitive or labile acyloxymethyl esters (=O)R99 and ymethyl ates CH2OC(=O)OR99 where R99 is C1C6 alkyl, C1C6 substituted alkyl, C6C20 aryl or C6C20 substituted aryl.

The acyloxyalkyl ester was first used as a prodrug strategy for carboxylic acids and then applied to phosphates and phosphonates by Farquhar et al. (1983) J. Pharm. Sci. 72: 324; also US Patent Nos. 4816570, 4968788, 5663159 and 5792756. Subsequently, the yalkyl 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 as a prodrug moiety in the compounds of the combinations of the disclosure. An exemplary acyloxymethyl ester is pivaloyloxymethoxy, (POM) CH2OC(=O)C(CH3)3. An exemplary ymethyl carbonate prodrug moiety is pivaloyloxymethylcarbonate (POC)  CH2OC(=O)OC(CH3)3.

Aryl esters of phosphorus groups, especially phenyl esters, are reported to enhance oral bioavailability (De rt 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). Benzyl esters are reported to generate parent onic acids. In some cases, substituents at the ortho- or para- position may accelerate the hydrolysis. Benzyl analogs with an acylated phenol or an ted phenol may 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 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 gs have been described containing a carboxylic ester-containing group attached to the benzylic ene (Glazier WO 91/19721). Thio-containing prodrugs are ed to be useful for the intracellular delivery of phosphonate drugs. These ers 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 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 disclosure, protecting groups include prodrug 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 gies for protection/deprotection are well known in the art. See e.g., Protective Groups in Organic try, Theodora W. Greene, John Wiley & Sons, Inc., New York, 1991. Protecting groups are often utilized to mask the reactivity of certain onal groups, to assist in the efficiency of desired chemical ons, e.g., making and breaking chemical bonds in an ordered and planned fashion. Protection of onal groups of a compound alters other physical properties besides the reactivity of 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 biologically active or inactive.

Protected nds 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 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, gs may possess greater y in vivo than the 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 ularly important that the ing products after deprotection, e.g., alcohols, be physiologically acceptable, gh in general it is more desirable if the ts are pharmacologically innocuous.

Protecting groups are available, commonly known and used, and are optionally used to prevent side reactions with the protected group during synthetic ures, i.e. routes or methods to prepare the compounds of the disclosure. 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 upon the chemistry of the reaction to be protected against (e.g., , basic, oxidative, reductive or other conditions) and the intended direction of the synthesis.

PGs do not need to be, and generally are not, the same if the compound is substituted with multiple PGs. In general, PG will be used to protect functional groups such as carboxyl, hydroxyl, thio, or amino groups and to thus prevent side reactions or to ise 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 disclosure may be 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 chemical protecting groups in the synthetic schemes set forth herein. However, some hydroxyl and thio protecting groups are neither ether- nor esterforming groups, as will be understood by those skilled in the art, and are included with amides, discussed below.

A very large number of yl protecting groups and amide-forming groups and corresponding al cleavage reactions are described in Protective Groups in Organic Synthesis, ra W. Greene (John Wiley & Sons, Inc., New York, 1991, ISBN 0 62301-6) ("Greene"). See also Kocienski, Philip J.; Protecting Groups (Georg Thieme Verlag Stuttgart, New York, 1994), which is orated by reference in its ty herein.

For protecting groups for ylic acid, phosphonic acid, phosphonate, sulfonic acid and other protecting groups for acids see Greene as set forth below.

By way of example and not limitation, variables described herein may 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 independently occur 12 or fewer times in a given embodiment. er a compound described herein is substituted with more than one of the same designated group, e.g., "R1" or "R3", then it will be understood that the groups may be the same or different, i.e., each group is ndently selected. Wavy lines indicate the site of covalent bond attachments to the adjoining groups, moieties, or atoms.

In one ment of the sure, the compound is in an isolated and purified form. Generally, the term "isolated and purified" means that the compound is substantially free from biological als (e.g. blood, tissue, cells, etc.). In one specific embodiment of the disclosure, the term means that the compound or conjugate of the disclosure is at least about 50 wt.% free from biological materials; in another specific embodiment, the term means that the nd or conjugate of the disclosure is at least about 75 wt.% free from biological materials; in another specific embodiment, the term means that the compound or conjugate of the disclosure is at least about 90 wt.% free from biological materials; in another specific embodiment, the term means that the compound or conjugate of the disclosure is at least about 98 wt.% free from biological als; and in another embodiment, the term means that the compound or conjugate of the disclosure is at least about 99 wt.% free from biological materials. In another specific embodiment, the disclosure es a compound or conjugate of the disclosure that has been tically prepared (e.g., ex vivo).

Stereoisomers The compounds of the disclosure may have chiral centers, e.g., chiral carbon or phosphorus atoms. The compounds of the disclosure thus include racemic mixtures of all stereoisomers, including enantiomers, diastereomers, and atropisomers. In on, the compounds of the disclosure include enriched or ed l isomers at any or all asymmetric, chiral atoms. In other words, the chiral centers apparent from the depictions are ed as the chiral isomers or racemic mixtures. Both racemic and diastereomeric mixtures, as well as the individual l isomers isolated or synthesized, substantially free of their enantiomeric or diastereomeric partners, are all within the scope of the disclosure.

The racemic mixtures are separated into their individual, substantially optically pure isomers through well-known techniques such as, for e, the 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 riate stereoisomer of the desired starting material.

The compounds of the disclosure can also exist as tautomeric isomers in certain cases. gh only one tautomer may be depicted, all such forms are contemplated within the scope of the sure. For example, ene-amine tautomers can exist for purine, pyrimidine, imidazole, guanidine, amidine, and tetrazole s and all their le tautomeric forms are within the scope of the disclosure.

Salts and Hydrates Examples of physiologically or pharmaceutically acceptable salts of the compounds of the disclosure include salts derived from an appropriate base, such as an alkali metal (for example, sodium), an alkaline earth metal (for example, magnesium), ammonium and NX4+ in X is C1-C4 alkyl).

For therapeutic use, salts of active ingredients of the compounds of the disclosure will typically be physiologically acceptable, i.e. they will be salts derived from a physiologically acceptable acid or base. r, salts of acids or bases which are not physiologically able may also find use, for e, in the preparation or purification of a physiologically acceptable compound. All salts, whether or not derived from a physiologically acceptable acid or base, are within the scope of the t disclosure.

Metal salts typically are prepared by ng the metal hydroxide with a nd of this disclosure. 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.

In addition, salts may be formed from acid addition of n organic and inorganic acids, e.g., HCl, HBr, H2SO4, H3PO4 or organic sulfonic acids, to basic centers, typically amines, or to acidic groups.

Compounds of the disclosure 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 liver. Compounds binding in the liver may bind with varying s of reversibility. Those nds binding substantially irreversibly are ideal candidates for use in this method of the disclosure. Once labeled, the substantially irreversibly binding compounds are useful as probes for the detection of HCV. Accordingly, the disclosure relates to methods of detecting NS3 in a sample suspected of ning HCV comprising the steps of: treating a sample suspected of containing HCV with a composition comprising a nd of the disclosure bound to a label; and observing the effect of the sample on the activity of the label. le labels are well known in the diagnostics field and include stable free radicals, fluorophores, radioisotopes, enzymes, chemiluminescent groups and chromogens. The compounds herein are labeled in conventional fashion using functional groups such as hydroxyl or amino. In one embodiment the disclosure provides a compound of any one of formulae (I) and (A1)-(A4) that ses or that is bound or linked to one or more detectable labels. Within the context of the disclosure samples suspected of containing HCV include l or man-made materials such as living organisms; tissue or cell cultures; biological samples such as biological al samples (blood, serum, urine, cerebrospinal fluid, tears, sputum, saliva, tissue samples, and the like); laboratory samples; food, water, or air samples; duct samples such as extracts of cells, particularly recombinant cells synthesizing a desired glycoprotein; and the like. Typically the sample will be suspected of containing 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 disclosure comprises adding the compound of the sure to the sample or it ses adding a precursor of the composition to the sample. The addition step comprises any method of administration as described above.

If d, the activity of HCV after ation of the compound can be observed by any method including direct and indirect methods of ing HCV activity. Quantitative, qualitative, and semiquantitative methods of determining HCV activity are all contemplated.

Typically one of the screening methods described above are d, however, any other method such as observation of the logical properties of a living organism are also applicable.

Many organisms contain HCV. The compounds of this disclosure are useful in the treatment or prophylaxis of ions ated with HCV activation in s or in man.

However, in screening nds capable of inhibiting HCV activity it should 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.

Metabolites of the Compounds Also falling within the scope of this sure are the in vivo metabolic products of the compounds described herein.

Accordingly, the disclosure includes compounds produced by a process comprising contacting a nd of this disclosure with a mammal for a period of time sufficient to yield a metabolic product thereof. Such products typically are identified by preparing a radiolabelled (e.g., C14 or H3) compound of the sure, 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 or other biological samples. These products are easily ed since they are labeled (others are isolated by the use of antibodies capable of binding es 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 well-known to those d in the art. The conversion products, so long as they are not otherwise found in vivo, are useful in diagnostic assays for therapeutic dosing of the compounds of the disclosure even if they possess no HCV –inhibitory activity of their own. s for ining stability of compounds in surrogate gastrointestinal secretions are known.

Exemplary s of Making the nds The disclosure also relates to methods of making the compositions of the disclosure.

The compositions are prepared by any of the applicable techniques of organic synthesis.

Many such techniques are well known in the art. However, many of the known ques are ated in Compendium of Organic 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; 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 c Synthesis. ivity, gy & Efficiency in Modern Organic try. In 9 Volumes, Barry M. Trost, Editor-in-Chief mon Press, New York, 1993 ng). Other methods suitable for preparing compounds of the disclosure are described in International Patent Application Publication Number .

A number of exemplary methods for the preparation of the compositions of the disclosure are provided in the schemes and examples below. These methods are intended to illustrate the nature of such preparations and are not intended to limit the scope of applicable methods.

Generally, the reaction conditions such as temperature, reaction time, solvents, workup procedures, and the like, will be those common in the art for the particular reaction to be performed. The cited reference material, together with al cited therein, contains detailed descriptions of such ions. 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 ts of quenching any unreacted reagents followed by partition between a 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 reductions frequently the temperature is reduced to 0°C to , solvents are typically aprotic for reductions and may be either protic or aprotic for oxidations. Reaction times are adjusted to achieve desired sions.

Condensation reactions are typically carried out at temperatures near room temperature, although for non-equilibrating, kinetically controlled condensations reduced temperatures (0°C to -100°C) are also common. ts can be either protic (common in equilibrating reactions) or aprotic (common in kinetically controlled reactions).

Standard synthetic techniques such as azeotropic removal of reaction by-products and use of anhydrous reaction conditions (e.g., inert gas environments) are common in the art and will be applied when able.

The terms "treated", ing", "treatment", and the like, when used in connection with a chemical synthetic operation, mean contacting, mixing, ng, 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 as to convert it to one or more other chemical entities. This means that "treating compound one with compound two" is synonymous with "allowing compound one to react with nd 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 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 0.1M to 1M), temperatures (-100°C to 250°C, typically -78°C to 150°C, more lly -78°C to 100°C, still more typically 0°C to 100°C), reaction vessels (typically glass, c, metal), solvents, pressures, atmospheres (typically air for oxygen and water insensitive ons or nitrogen or argon for oxygen or water sensitive), etc., are ed unless otherwise indicated. The dge of similar reactions known in the art of organic synthesis is 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 ions and apparatus reasonably ed to successfully carry out the chemical reactions of the described processes based on the knowledge in the art.

Modifications of each of the exemplary schemes and in the Examples (hereafter lary schemes") leads to various s of the specific exemplary materials produced.

The above-cited citations describing le methods of organic synthesis are able to such cations.

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 hase extraction, crystallization 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 ative thin or thick layer chromatography, as well as techniques of small scale thin layer and flash chromatography. r class of separation methods involves treatment of a mixture with a reagent ed to bind to or render otherwise separable a desired product, unreacted starting material, reaction by product, or the like. Such ts 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 as antibodies, binding proteins, selective chelators such as crown ethers, liquid/liquid ion extraction ts (LIX), or the like.

Selection of appropriate methods of separation s on the nature of the materials involved. For example, boiling point, and molecular weight in distillation and sublimation, presence or absence of polar functional groups in chromatography, stability of materials in acidic and basic media in multiphase tion, and the like. One skilled in the art will apply techniques most likely to achieve the d tion.

A single stereoisomer, e.g., an enantiomer, substantially free of its 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 disclosure can be separated and isolated by any suitable method, including: (1) formation of ionic, diastereomeric salts with chiral nds and separation by fractional crystallization or other methods, (2) ion 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 chiral conditions.

Under method (1), diastereomeric salts can be formed by reaction of enantiomerically pure chiral bases such as brucine, e, ephedrine, strychnine, -methyl-- phenylethylamine tamine), and the like with asymmetric compounds bearing acidic functionality, such as carboxylic acid and sulfonic acid. The reomeric salts may be induced to te by fractional crystallization or ionic chromatography. For separation of the optical isomers of amino compounds, addition of chiral ylic or sulfonic acids, such as camphorsulfonic acid, tartaric acid, mandelic acid, or lactic acid can result in formation of the diastereomeric salts.

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, Inc., p. 322).

Diastereomeric compounds can be formed by reacting asymmetric compounds with enantiomerically pure chiral derivatizing reagents, such as menthyl tives, followed by separation of the diastereomers and hydrolysis to yield the free, enantiomerically enriched substrate. A method of determining optical purity involves making chiral , such as a menthyl ester, e.g., (-) menthyl formate in the presence of base, or Mosher ester, - methoxy--(trifluoromethyl)phenyl acetate (Jacob III. (1982) J. Org. Chem. 5), of the racemic mixture, and analyzing the NMR spectrum for the presence of the two atropisomeric diastereomers. Stable diastereomers of someric compounds 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, 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. s and Examples General aspects of these exemplary methods are described below and in the es. Each of the products of the following ses is optionally separated, isolated, and/or purified prior to its use in subsequent processes.

A number of exemplary methods for the preparation of compounds of the disclosure are provided herein, for example, in the Examples below. These methods are intended to illustrate the nature of such preparations and are not intended to limit the scope of applicable methods. Certain compounds of the sure can be used as intermediates for the preparation of other compounds of the disclosure. In the exemplary s described herein, the nt E-V- can also be written as R9-.

The percentage of the compound remaining after incubation at each time point is calculated by comparing with the sampling at the start of incubation.

Stability in Rat, Dog, Monkey and Human Plasma: Compounds will be incubated for up to 2 hours in plasma (rat, dog, monkey, or human) at 37°C. Compounds are added to the plasma at final concentrations of 1 and 10 µg/mL. Aliquots are taken at 0, 5, 15, 30, 60, and 120 minutes after adding the compound. Concentration of compounds and major metabolites at each time point are measured by LC/MS/MS.

Evaluation of cell-based anti-HCV activity: Antiviral potency (EC50) was ined using a a luciferase -based HCV replicon reporter assay. To perform the assay for genotype 1 and 2a JFH-1, stable HCV 1a RLuc replicon cells (harboring a dicistronic genotype 1a H77 replicon that encodes a RLuc reporter), stable HCV 1b RLuc replicon cells (harboring a dicistronic genotype 1b Con1 replicon that s a RLuc reporter), or stable HCV 2a JFH-1 Rluc replicon cells (harboring a dicistronic genotype 2a JFH-1 replicon that encodes a RLuc reporter; with L31 present in NS5A) were dispensed into ll plates for EC50 assays. To perform the assay for pe 2a (with M31 present in NS5A) or 2b, NS5A chimeric genotype 2a JFH-1 replicons that encodes a RLuc-Neo reporter and either genotype 2a J6 strain NS5A gene or pe 2b MD2b-1 strain NS5A gene (both with M31 present) respectively, were either transiently transfected (t) into Huh- Lunet cells or were established as stably replicating replicon cells (s) is provided. Either cells were dispensed into 384-well plates for EC50 assays. To perform the assay for genotype 3 and 4, NS5A chimeric genotype 1b Con1 replicons that encodes a Pi-RLuc reporter and either genotype 3a S52 strain NS5A gene or genotype 4a ED43 strain NS5A gene respectively, were transiently transfected (t) into Huh-Lunet cells, which were subsequently dispensed into 384-well plates. Compounds were dissolved in DMSO at a concentration of 10 mM and diluted in DMSO either manually or using an automated pipeting instrument. Serially 3-fold d compounds were either manually mixed with cell culture media and added to the seeded cells or directly added to the cells using an automated ment. DMSO was used as a negative (solvent; no inhibition) l, and the protease inhibitor ITMN-191 was included at a tration > 100 x EC50 as a positive control. 72 hours later, cells were lysed and Renilla luciferase activity quantified as recommended by the manufacturer (Promega- Madison, WI). Non-linear regression was performed to calculate EC50 values.

To determine the antiviral potency (EC50) t ance mutants, resistance mutations, including M28T, Q30R, Q30H, L31M, and Y93C in genotype 1a NS5A and Y93H in genotype 1b NS5A, were uced dually into either 1a Pi-Rluc or 1b Pi- Rluc replicons by site directed mutagenesis. on RNA of each resistant mutant was transiently transfected into Huhderived cured-51 cells and antiviral potency was determined on these transfected cells as described above.

The EC50 ranges for genotype 1a, 1a Q30R, and 2a JFH are as s: A ≥ 44 nM, B = 1 nM to 43.99 nM, C < 1 nM. The EC50 ranges for pe 2a J6, 2b, 3a, and 4a are as s: A ≥ 5 nM, B = 1 nM to 4.99 nM, C < 1 nM. The EC50 ranges for genotype 2a J6, 2b, and 4a correspond to the assay of transiently transfected cells (t). If this data is unavailable, the EC50 range for the stably replicating cells (s) is provided.

IV and PO Single Dose Pharmacokinetic Studies in SD Rats: The pharmacokinetics of selected compounds was characterized in male Sprague-Dawley (SD) rats (250-300g). In this study, two groups of naïve purebred SD rats (N=3 per group, fasted over night) ed the selected compound either as an intravenous (IV) infusion (1 mg/kg over 30 minutes) via the jugular vein or by oral gavage (2 mg/kg). The intravenous (IV) dosing vehicle was 5% ethanol, 35% polyethylene glycol 400 (PEG 400) and 60% water pH 2.0. The oral dosing vehicle was 5% ethanol, 55% PEG 400 and 40% citrate buffer pH 2.2.

Serial blood samples (approximately 0.3 mL each) were collected from jugular vein or other suitable vein at specified time points. For the IV infusion group, the blood samples were collected predose and at 0.25, 0.48, 0.58, 0.75, 1.5, 3, 6, 8, 12 and 24 hours after the start of on. For the oral group, the blood samples were collected predose and at 0.25, 0.50, 1, 2, 4, 6, 8, 12 and 24 hours after dosing. The blood s were collected into Vacutainer tubes containing EDTA-K3 as the oagulant and were fuged at approximately 4ºC to obtain plasma. The plasma s were stored at -20ºC until analysis by LC/MS/MS.

A bioanalytical method utilizing high performance liquid chromatography coupled to tandem mass spectrometry (LC/MS/MS) was developed for analysis of the selected compound in rat plasma. Detection was performed using selected reaction ring (SRM); Ions representing the sor (M+H)+ species was selected in quadrupole 1 (Q1) and collided with argon gas in the collision cell (Q2) to generate specific product ion, which was subsequently monitored by quadrupole 3 (Q3). Standard curve and quality control samples were prepared in male rat plasma and processed in the same way as the test samples to generate quantitative data. cokinetic parameters were generated using non-compartmental pharmacokinetic analysis (Phoenix WinNonlin, version 6.3). Values below the lower limit of quantification (LLOQ) were assigned a value of zero if predose and treated as missing thereafter. Area under the curve (AUC) was calculated using the linear trapezoidal rule. The oral bioavailability (%F) was determined by comparison of the area under the curve (AUC) of the compound and/or a metabolite generated in plasma following oral administration to that generated following intravenous administration. # e 1b 1a 1a 2a 2a 2b 3a 4a 1a 1a 2a 2a J6 2a J6 2b (t) 2b (s) 3a 4a (t) 4a (s) Rat %F No. (nM) Q30R JFH J6 (nM) Q30R JFH (t) (s) (nM) (nM) (nM) (nM) (nM) (nM)
