WSGR Docket No. 41223-754.601 ORALLY-BIOAVAILABLE NUCLEOSIDE ANALOGS CROSS-REFERENCE [0001] This application claims the benefit of U. S. Provisional Application Serial No.63/387,392 filed December 14, 2022 which is hereby incorporated by reference in its entirety. BACKGROUND [0002] Remdesivir is a parenterally administered prodrug that was previously developed for the treatment of Ebola virus disease and more recently received emergency use authorization for the treatment of severe acute respiratory syndrome-coronavirus 2 (SARS-CoV-2) infection (Eastman, R.T., Roth, J.S., Brimacombe, K.R., Simeonov, A., Shen, M., Patnaik, S., and Hall, M.D. (2020). Remdesivir: A Review of Its Discovery and Development Leading to Emergency Use Authorization for Treatment of COVID-19. ACS Cent Sci 6, 672-683). The parent compound is a 1′-cyano modified adenosine C- nucleoside analog (GS-441524) that is phosphorylated by intracellular nucleotide kinases to the active tri-phosphorylated form (GS-443902). GS-443902 inhibits viral replication by competing with adenosine 5’-triphosphate for incorporation into nascent RNA chains by the virally-encoded RNA-dependent RNA polymerase leading to a delayed chain termination that can occur three nucleotides downstream from its position (Kokic et a., 2021; Nature Communications 12:279). In full-length read-through transcripts, the presence of GS-443902 residues in the template strand significantly compromises the incorporation of uridine residues during second-strand synthesis (Tchesnokov et al.2020 Journal of Biological Chemistry 295(47):16156-16165). Remdesivir (GS-5734) is a monophosphoramidate prodrug of GS-441524 and demonstrates broad spectrum antiviral activity against a wide range of different RNA virus families including: filoviruses (e.g. Ebola viruses, Marburg virus), paramyxoviruses (e.g. parainfluenza type II virus, Nipah virus, Hendra virus, measles morbillivirus, mumps virus), coronaviruses (e.g. SARS-CoV, SARS-CoV-2, MERS-CoV), and pneumoviruses (e.g. respiratory syncytial virus) (Cho, A., Saunders, O.L., Butler, T., Zhang, L., Xu, J., Vela, J.E., Feng, J.Y., Ray, A.S., and Kim, C.U. (2012). Synthesis and antiviral activity of a series of 1'-substituted 4-aza-7,9-dideazaadenosine C-nucleosides. Bioorg Med Chem Lett 22, 2705-2707). [0003] Coronaviruses (CoV) are a large family of viruses that typically infect the upper respiratory tract causing mild to moderate disease in humans. Infections with human coronaviruses: 229E, NL63, OC43 and HKU1 account for approximately 5-30% of “common” colds. There are several hundred coronaviruses that circulate in animals such as pigs, camels, bats, and cats. In the past twenty years, at least three coronaviruses have jumped from one or more of these animal reservoirs into humans in what is known as a spillover event. One example is “Middle East Respiratory Syndrome Coronavirus” (MERS-CoV or MERS) which was first reported in Saudi Arabia in 2012. Another example is SARS- CoV, the coronavirus responsible for “Severe Acute Respiratory Syndrome” (SARS) that was first identified in China in 2002. Still another example is SARS-CoV-2, the causative agent of COVID-19
WSGR Docket No. 41223-754.601 (Coronavirus Disease of 2019). All three of these beta-coronaviruses, SARS-CoV, MERS-CoV, and SARS-CoV-2, have shown the potential to replicate in the lower respiratory tract and cause more serious illnesses in humans giving rise to a viral pneumonia that can be fatal. Other clinical manifestations and organ system complications (i.e., cardiac, neurologic, hematologic) have also been described in patients who are infected with SARS-CoV-2.

Further Forms of Compounds Disclosed Herein Isomers/Stereoisomers [00256] In some embodiments, the compounds described herein exist as geometric isomers. In some embodiments, the compounds described herein possess one or more double bonds. The compounds presented herein include all cis, trans, syn, anti, entgegen (E), and zusammen (Z) isomers as well as the corresponding mixtures thereof. In some situations, the compounds described herein possess one or more chiral centers and each center exists in the R configuration, or S configuration. The compounds described herein include all diastereomeric, enantiomeric, and epimeric forms as well as the corresponding mixtures thereof. In additional embodiments of the compounds and methods provided herein, mixtures of enantiomers and/or diastereoisomers, resulting from a single preparative step, combination, or
WSGR Docket No. 41223-754.601 interconversion are useful for the applications described herein. In some embodiments, the compounds described herein are prepared as their individual stereoisomers by reacting a racemic mixture of the compound with an optically active resolving agent to form a pair of diastereoisomeric compounds, separating the diastereomers and recovering the optically pure enantiomers. In some embodiments, dissociable complexes are preferred. In some embodiments, the diastereomers have distinct physical properties (e.g., melting points, boiling points, solubilities, reactivity, etc.) and are separated by taking advantage of these dissimilarities. In some embodiments, the diastereomers are separated by chiral chromatography, or preferably, by separation/resolution techniques based upon differences in solubility. In some embodiments, the optically pure enantiomer is then recovered, along with the resolving agent, by any practical means that would not result in racemization. Labeled compounds [00257] In some embodiments, the compounds described herein exist in their isotopically -labeled forms. In some embodiments, the methods disclosed herein include methods of treating diseases by administering such isotopically-labeled compounds. In some embodiments, the methods disclosed herein include methods of treating diseases by administering such isotopically -labeled compounds as pharmaceutical compositions. Thus, in some embodiments, the compounds disclosed herein include isotopically-labeled compounds, which are identical to those recited herein, but for the fact that one or more atoms are replaced by an atom having an atomic mass or mass number different from the atomic mass or mass number usually found in nature. Examples of isotopes that can be incorporated into compounds disclosed herein include isotopes of hydrogen, carbon, nitrogen, oxygen, phosphorous, sulfur, fluorine, and chloride, such as
2H,
3H,
13C,
14C,
l5N,
18O,
17O,
31P,
32P,
35S,
18F, and
36Cl, respectively. Compounds described herein, and the pharmaceutically acceptable salts, solvates, or stereoisomers thereof which contain the aforementioned isotopes and/or other isotopes of other atoms are within the scope of this invention. Certain isotopically-labeled compounds, for example those into which radioactive isotopes such as
3H and
14C are incorporated, are useful in drug and/or substrate tissue distribution assays. Tritiated, i.e.,
3H and carbon-14, i.e.,
14C, isotopes are particularly preferred for their ease of preparation and detectability. Further, substitution with heavy isotopes such as deuterium, i.e.,
2H, produces certain therapeutic advantages resulting from greater metabolic stability, for example increased in vivo half-life or reduced dosage requirements. [00258] In some embodiments, the compounds described herein are labeled by other means, including, but not limited to, the use of chromophores or fluorescent moieties, bioluminescent labels, or chemiluminescent labels. Pharmaceutically acceptable salts [00259] In some embodiments, the compounds described herein exist as their pharmaceutically acceptable salts. In some embodiments, the methods disclosed herein include methods of treating diseases by administering such pharmaceutically acceptable salts. In some embodiments, the methods
WSGR Docket No. 41223-754.601 disclosed herein include methods of treating diseases by administering such pharmaceutically acceptable salts as pharmaceutical compositions. [00260] In some embodiments, the compounds described herein possess acidic or basic groups and therefore react with any of a number of inorganic or organic bases, and inorganic and organic acids, to form a pharmaceutically acceptable salt. In some embodiments, these salts are prepared in situ during the final isolation and purification of the compounds disclosed herein, or a solvate, or stereoisomer thereof , or by separately reacting a purified compound in its free form with a suitable acid or base, and isolating the salt thus formed. [00261] Examples of pharmaceutically acceptable salts include those salts prepared by reaction of the compounds described herein with a mineral, organic acid or inorganic base, such salts including, acetate, acrylate, adipate, alginate, aspartate, benzoate, benzenesulfonate, bisulfate, bisulfite, bromide, butyrate, butyn-1,4-dioate, camphorate, camphorsulfonate, caproate, caprylate, chlorobenzoate, chloride, citrate, cyclopentanepropionate, decanoate, digluconate, dihydrogenphosphate, dinitrobenzoate, dodecylsulfate, ethanesulfonate, formate, fumarate, glucoheptanoate, glycerophosphate, glycolate, hemisulfate, heptanoate, hexanoate, hexyne-1,6-dioate, hydroxybenzoate, γ-hydroxybutyrate, hydrochloride, hydrobromide, hydroiodide, 2-hydroxyethanesulfonate, iodide, isobutyrate, lactate, maleate, malonate, methanesulfonate, mandelate metaphosphate, methanesulfonate, methoxybenzoate, methylbenzoate, monohydrogenphosphate, 1-napthalenesulfonate, 2-napthalenesulfonate, nicotinate, nitrate, palmoate, pectinate, persulfate, 3-phenylpropionate, phosphate, picrate, pivalate, propionate, pyrosu lfate, pyrophosphate, propiolate, phthalate, phenylacetate, phenylbutyrate, propanesulfonate, salicylate, succinate, sulfate, sulfite, succinate, suberate, sebacate, sulfonate, tartrate, thiocyanate, tosylateundeconate and xylenesulfonate. [00262] Further, the compounds described herein can be prepared as pharmaceutically acceptable salts formed by reacting the free base form of the compound with a pharmaceutically acceptable inorganic or organic acid, including, but not limited to, inorganic acids such as hydrochloric acid, hydrobromic acid, sulfuric acid, nitric acid, phosphoric acid metaphosphoric acid, and the like; and organic acids such as acetic acid, propionic acid, hexanoic acid, cyclopentanepropionic acid, glycolic acid, pyruvic acid, lactic acid, malonic acid, succinic acid, malic acid, maleic acid, fumaric acid, p-toluenesulfonic acid, tartaric acid, trifluoroacetic acid, citric acid, benzoic acid, 3-(4-hydroxybenzoyl)benzoic acid, cinnamic acid, mandelic acid, arylsulfonic acid, methanesulfonic acid, ethanesulfonic acid, 1,2-ethanedisulfonic acid, 2- hydroxyethanesulfonic acid, benzenesulfonic acid, 2-naphthalenesulfonic acid, 4-methylbicyclo- [2.2.2]oct-2-ene-1-carboxylic acid, glucoheptonic acid, 4,4’-methylenebis-(3-hydroxy-2-ene-1 - carboxylic acid), 3-phenylpropionic acid, trimethylacetic acid, tertiary butylacetic acid, lauryl sulfuric acid, gluconic acid, glutamic acid, hydroxynaphthoic acid, salicylic acid, stearic acid and muconic acid. In some embodiments, other acids, such as oxalic, while not in themselves pharmaceutically acceptable, are employed in the preparation of salts useful as intermediates in obtaining the compounds disclosed herein, solvate, or stereoisomer thereof and their pharmaceutically acceptable acid addition salts.
WSGR Docket No. 41223-754.601 [00263] In some embodiments, those compounds described herein which comprise a free acid group react with a suitable base, such as the hydroxide, carbonate, bicarbonate, sulfate, of a pharmaceutically acceptable metal cation, with ammonia, or with a pharmaceutically acceptable organic primary, secondary, tertiary, or quaternary amine. Representative salts include the alkali or alkaline earth salts, like lithium, sodium, potassium, calcium, and magnesium, and aluminum salts and the like. Illustrative examples of bases include sodium hydroxide, potassium hydroxide, choline hydroxide, sodium carbonate, N
+(C
1-4 alkyl)
4, and the like. [00264] Representative organic amines useful for the formation of base addition salts include ethylamine, diethylamine, ethylenediamine, ethanolamine, diethanolamine, piperazine and the like. It should be understood that the compounds described herein also include the quaternization of any basic nitrogen-containing groups they contain. In some embodiments, water or oil-soluble or dispersible products are obtained by such quaternization. Solvates [00265] In some embodiments, the compounds described herein exist as solvates. The invention provides for methods of treating diseases by administering such solvates. The invention further provides for methods of treating diseases by administering such solvates as pharmaceutical compositions. [00266] Solvates contain either stoichiometric or non-stoichiometric amounts of a solvent, and, in some embodiments, are formed with pharmaceutically acceptable solvents such as water, ethanol, and the like. Hydrates are formed when the solvent is water, or alcoholates are formed when the solvent is alcohol. Solvates of the compounds described herein can be conveniently prepared or formed during the processes described herein. By way of example only, hydrates of the compounds described herein can be conveniently prepared from an aqueous/organic solvent mixture, using organic solvents including, but not limited to, dioxane, tetrahydrofuran or methanol. In addition, the compounds provided herein can exist in unsolvated as well as solvated forms. In general, the solvated forms are considered equivalent to the unsolvated forms for the purposes of the compounds and methods provided herein. Tautomers [00267] In some situations, compounds exist as tautomers. The compounds described herein include all possible tautomers within the formulas described herein. Tautomers are compounds that are interconvertible by migration of a hydrogen atom, accompanied by a switch of a single bond and adjacent double bond. In bonding arrangements where tautomerization is possible, a chemical equilibrium of the tautomers will exist. All tautomeric forms of the compounds disclosed herein are contemplated. The exact ratio of the tautomers depends on several factors, including temperature, solvent, and pH. Prodrugs [00268] “Prodrug” is meant to indicate a compound that is, in some embodiments, converted under physiological conditions or by solvolysis to a biologically active compound described herein. Thus, the term “prodrug” refers to a precursor of a biologically active compound that is pharmaceutically acceptable. A prodrug is typically inactive when administered to a subject, but is converted in vivo to an
WSGR Docket No. 41223-754.601 active compound, for example, by hydrolysis. The prodrug compound often offers advantages of solubility, tissue compatibility or delayed release in a mammalian organism (see, e.g., Bundgard, H., Design of Prodrugs (1985), pp.7-9, 21-24 (Elsevier, Amsterdam). Prodrugs are delivered through any known methods described herein, including but not limited to orally, intravenously, intraperitoneal, or other method of administration known by those skilled in the art. [00269] A discussion of prodrugs is provided in Higuchi, T., et al., “Pro-drugs as Novel Delivery Systems,” A.C.S. Symposium Series, Vol.14, and in Bioreversible Carriers in Drug Design, ed. Edward B. Roche, American Pharmaceutical Association and Pergamon Press, 1987. [00270] The term “prodrug” is also meant to include any covalently bonded carriers, which release the active compound in vivo when such prodrug is administered to a mammalian subject. Prodrugs of an active compound, as described herein, are prepared by modifying functional groups present in the active compound in such a way that the modifications are cleaved, either in routine manipulation or in vivo, to the parent active compound. Prodrugs include compounds wherein a hydroxy, amino or mercapto group is bonded to any group that, when the prodrug of the active compound is administered to a mammalian subject, cleaves to form a free hydroxy, free amino or free mercapto group, respectively. In some embodiments, prodrugs include any group bound to a heteroatom, such as the nitrogen of a pyridine which is cleaved in vivo to form the active compound or metabolite thereof. Examples of prodrugs include, but are not limited to, acetate, formate phosphate, and benzoate derivatives of alcohol or amine functional groups in the active compounds and the like. [00271] In some embodiments, a prodrug is a salt. In some embodiments, a prodrug is a phosphate salt. In some embodiments, a prodrug is an alkyl phosphate salt. In some embodiments, a prodrug is an alkylated heteroaromatic salt. In some embodiments, a prodrug is a pyridinium salt. In some embodiments, a prodrug is a pyridinium alkylphosphate salt. In some embodiments, a prodrug is a pyridinium methylphosphate salt. In some embodiments, a prodrug comprises an alkyl phosphate bound to a heteroatom. In some embodiments, a prodrug comprises an alkyl phosphate bound to a heteroatom of a heterocycle. [00272] In some embodiments, a prodrug is any compound that when administered to a biological system generates a biologically active compound as a result of spontaneous chemical reaction(s), enzyme catalyzed chemical reaction(s), and/or metabolic chemical reaction(s), or a combination of each. In other embodiments, prodrugs are formed using groups attached to functionality, e.g., HO—, HS—, HOOC—, NHR—, associated with the drug or active compounds, that cleave in vivo. In some embodiments, prodrugs include but are not limited to carboxylate esters where the group is alkyl, aryl, aralkyl, acyloxyalkyl, alkoxycarbonyloxyalkyl as well as esters of hydroxyl, thiol, and amines where the group attached is an acyl group, an alkoxycarbonyl, aminocarbonyl, phosphate or sulfate. The groups illustrated above are exemplary, not exhaustive, and other varieties of prodrugs are possible. Such prodrugs of disclosed compounds fall within this scope. In some embodiments, the compounds of the present
WSGR Docket No. 41223-754.601 application are prodrugs themselves and are converted into other forms, including the biologically active compound forms, when administered to a biological system. [00273] In some embodiments, prodrugs undergo some form of a chemical transformation to produce the compound that is biologically active or is a precursor of the biologically active compound. In some cases, the prodrug is biologically active, more, or less than the intended active drug itself, and serves to improve drug efficacy or safety through improved oral bioavailability, and/or pharmacodynamic half-life, etc. Prodrug forms of compounds are utilized, for example, to improve bioavailability, improve subject acceptability such as by masking or reducing unpleasant characteristics such as bitter taste or gastrointestinal irritability, alter solubility such as for intravenous use, provide for prolonged or sustained release or delivery, improve ease of formulation, or provide site-specific delivery of the compound. Prodrugs are described in The Organic Chemistry of Drug Design and Drug Action, by Richard B. Silverman, Academic Press, San Diego, 1992, Chapter 8: “Prodrugs and Drug delivery Systems” pp. 352-401; Design of Prodrugs, edited by H. Bundgaard, Elsevier Science, Amsterdam, 1985; Design of Biopharmaceutical Properties through Prodrugs and Analogs, Ed. by E. B. Roche, American Pharmaceutical Association, Washington, 1977; and Drug Delivery Systems, ed. by R. L. Juliano, Oxford Univ. Press, Oxford, 1980. [00274] In some embodiments, prodrugs comprise phosphorus moieties includ ing phosphates or derivatives thereof. One such class of prodrugs is the aryl amidate (McGuigan) type.

Preparation of Compounds [00328] The size and scale of the synthetic methods will vary depending on the desired amount of end product. It is understood that while specific reactants and amounts are provided in the Examples, one of skill in the art knows other alternative and equally feasible sets of reactants that will also yield the same compounds. Thus, where general oxidizers, reducers, solvents of various nature (aprotic, apolar, polar, etc.) are utilized, equivalents will be known in the art and are herein contemplated for use in the present methods.
WSGR Docket No. 41223-754.601 [00329] For instance, in all instances, where a drying agent is used, contemplated drying agents include all those reported in the literature and known to one of skill, such as, but not limited to, magnesium sulfate, sodium sulfate, calcium sulfate, calcium chloride, potassium chloride, potassium hydroxide, sulfuric acid, quicklime, phosphorous pentoxide, potassium carbonate, sodium, silica gel, aluminum oxide, calcium hydride, lithium aluminum hydride (LAH), potassium hydroxide, and the like. (See, Burfield et al., “Desiccant Efficiency in Solvent Drying. A Reappraisal by Application of a Novel Method for Solvent Water Assay,” J. Org. Chem., 42(18):3060-3065, 1977). The amount of drying agent to add in each work up may be optimized by one of skill in the art and is not particularly limited. Further, although general guidance is provided for work-up of the intermediates in each step, it is generally understood by one of skill that other optional solvents and reagents may be equally substituted during the work-up steps. However, in some exceptional instances, it was found the very specific work-up conditions are required to maintain an unstable intermediate. Those instances are indicated below in the steps in which they occur. [00330] Many of the steps below indicate various work-ups following termination of the reaction. A work-up involves generally quenching of a reaction to terminate any remaining catalytic activity and starting reagents. This is generally followed by addition of an organic solvent and separation of the aqueous layer from the organic layer. The product is typically obtained from the organic layer and unused reactants and other spurious side products and unwanted chemicals are generally trapped in the aqueous layer and discarded. The work-up in standard organic synthetic procedures found throughout the literature is generally followed by drying the product by exposure to a drying agent to remove any excess water or aqueous byproducts remaining partially dissolved in the organic layer and concentration of the remaining organic layer. Concentration of product dissolved in solvent may be achieved by any known means, such as evaporation under pressure, evaporation under increased temperature and pressure, and the like. Such concentrating may be achieved by use of standard laboratory equipment such as rotary- evaporator distillation, and the like. This is optionally followed by one or more purification steps which may include, but is not limited to, flash column chromatography, filtration through various media and/or other preparative methods known in the art. (See, for instance, Addison Ault, “Techniques and Experiments for Organic Chemistry,” 6
th Ed., University Science Books, Sausalito, Calif., 1998, Ann B. McGuire, Ed., pp.45-59). Though certain organic co-solvents and quenching agents may be indicated in the steps described below, other equivalent organic solvents and quenching agents known to one of skill may be employed equally as well and are fully contemplated herein. Further, most of the work -ups in most steps may be further altered according to preference and desired end use or end product. Drying and evaporation, routine steps at the organic synthetic chemist bench, need not be employed and may be considered in all steps to be optional. The number of extractions with organic solvent may be as many as one, two, three, four, five, or ten or more, depending on the desired result and scale of reaction. Except where specifically noted, the volume, amount of quenching agent, and volume of organic solvents used in
WSGR Docket No. 41223-754.601 the work-up may be varied depending on specific reaction conditions and optimized to yield the best results. [00331] Additionally, where inert gas or noble gas is indicated, any inert gas commonly used in the art may be substituted for the indicated inert gas, such as argon, nitrogen, helium, neon, etc. EXAMPLES [00332] Examples below are intended to illustrate the general procedures used for preparing the compounds of the present invention. [00333] While preferred embodiments of the present invention have been shown and described herein, it will be obvious to those skilled in the art that such embodiments are provided by way of example only. Numerous variations, changes, and substitutions will now occur to those skilled in the art without departing from the invention. It should be understood that various alternatives to the embodiments of the invention described herein may be employed in practicing the invention. It is intended that the following claims define the scope of the invention and that methods and structures within the scope of these claims and their equivalents be covered thereby. Example 1.

[00444] The bidirectional permeability of compounds across the Caco-2 cell monolayer was assessed. The Caco-2 model is a widely used in vitro model for small intestinal absorption and potential for efflux. [00445] Cell culture. Caco-2 cells were grown in DMEM supplemented with 10% fetal bovine serum (FBS), 1% Penicillin-Streptomycin and 1% MEM NEAA. The cells were incubated at 37 °C, 5% CO
2/95% air and saturated humidity. After reaching 80-90% confluency, the cells were gently detached with trypsin. Cells at passage 39 were seeded on the 24-well BD insert system at the density of 8×104 cells/cm
2 and cultured for 19 days with medium changed every 2-3 days. Measure the transepithelial electrical resistance (TEER) value of each well. The wells can be used only when their TEER values are greater than 600 Ohms/cm
2. [00446] Transport assay. After removing the cell culture medium from the 24-well insert plate, the cells were rinsed with warm transport buffer. Appropriate dosing and receiving solutions were applied to the donor and receiver chambers to initiate the transport assay in apical to basolateral (A to B) or basolateral to apical (B to A) directions (500 and 1300 µL for apical and basolateral wells, respectively). Duplicate wells in each direction were used for the test compound and control compound. The plate was incubated in CO
2 incubator at 37 °C, with 5% CO
2/95% air and saturated humidity without shaking. The sample after 10-minute incubation was used as the T
0 sample, and the sample after 90-minute incubation was used as the T90 sample. T0 and T90 samples were collected from the donor and receiver side of each well at the designed timepoint, mixed with the transport buffer and acetonitrile/MeOH (1:1, v/v) and the internal standard for LC/MS/MS analysis. All samples were vortexed and centrifuged at 4000 rpm at 4 °C for 15 minutes, diluted with pure water and stored at 4 °C before bioanalysis by LC/MS/MS.

app, cm/s), efflux ratio (ER) and recovery parameters were calculated for Caco-2 drug transport assay using the following equations:
where V
R is the solution volume in the receiver chamber (0.4 mL on the apical side, 1.2 mL on the basolateral side); Area is the surface area for the insert membrane, i.e., 0.3 cm
2 for the area of the monolayer; Time is incubation time, expressed in seconds, i.e., 5400 s (90 min) for the current experiment; C
0 is the initial concentration of test compound or peak area ratio of control compounds in the donor chamber (µM); V
D is the volume in the donor chambers (0.4 mL on the apical side, 1.2 mL on the basolateral side); C
D and C
R are the final concentrations of test compounds or peak area ratio of control compounds in donor and receiver chambers, respectively. [00449] Data for representative compounds is shown in Table 2. Compounds with P
app < 1.0 are classified as low permeability, P
app between 1-10 are classified as medium permeability, and P
app ≥ 10 are classified as high permeability. An efflux ratio (ER) > 2 indicates the compounds are potential substrates for intestinal cell efflux transporters. Table 2. Bidirectional Caco-2 permeability assay results.

EXAMPLE IV: Evaluation of stability of example compounds in human fasted-state simulated gastric fluid, and fasted-state simulated intestinal fluid. [00452] The chemical stability of example compounds was determined using human fasted -state simulated gastric fluid, and fasted-state simulated intestinal fluid, prepared as follows. [00453] FaSSGF: • Weigh 1.0 g NaCl and dissolved it in 0.49 L water • Adjust pH value to 1.2, and adjust volume to 0.5 L in water • Filter the NaCl/HCl buffer through a 0.22 µm filter • Weigh 3.0 mg FaSSGF powder (Vendor: Biorelevant, catalog # FFF01), dissolve it in 50 mL NaCl/HCl buffer • Dissolve the FaSSGF powder in NaCl/HCl buffer and make up the volume to 50 mL • Store at 4 °C for future use. [00454] FaSSIF: • Weigh 0.695 g NaOH, 1.115 g maleic acid and 2.005 g NaCl, and dissolve in 0.49 L water
WSGR Docket No. 41223-754.601 • Adjusted the pH value to 6.8 and adjust volume to 0.5 L with water • Filter the maleic acid buffer through a 0.22 µm filter • Weigh 89.5 mg FaSSIF-V2 powder (Vendor: Biorelevant catalog # V2FAS01), dissolve in 50 mL maleic buffer • Dissolve the FaSSIF-V2 powder in maleic buffer and make up the volume to 50 mL • Store at 4 °C for future use. [00455] Briefly, test compounds were prepared as 50 µM working solutions in DMSO, and 2 µL test compound working solution was added to 98 µL of each buffer respectively in six tubes (for six timepoints, 0, 5, 15, 30, 60, and 120 min) and gently mixed. At each corresponding timepoint, the reaction was stopped by addition of 300 µL of quenching solution (methanol solution of 5 ng/mL terfenadine and 10 ng/mL of tolbutamide). Each tube was vortexed for 1 min, centrifuged at 4,000 rpm at 4 °C for 15 min, then 200 µL of supernatant was removed. The half-life of each example compound was determined using LC-MS/MS analysis, using the internal standards present in the quenching solution. [00456] Stability data for selected compounds of the invention is shown in Table 4. Table 4.

EXAMPLE V: Evaluation of SARS-CoV-2 RNA-dependent RNA polymerase inhibitory activity of nucleoside triphosphate derivatives. [00457] The ability of selected amide-derivatized nucleoside triphosphates to inhibit the SARS-CoV-2 RNA-dependent RNA polymerase was assessed in a commercially-available biochemical assay (performed by BPS Bioscience Inc., 6405 Mira Mesa Blvd., Ste. 100, San Diego, CA 92121, USA).

Assay Conditions [00458] The RdRp reactions were conducted in duplicate at 37 °C for 60 min in a 10 µL mixture containing assay buffer, RNA duplex, ATP substrate and enzyme, and the test compound. These 10 µL reactions were carried out in wells of 384-well white plate (Nunc). Dilutions of the test compounds were prepared in assay buffer (5% DMSO concentration) and 2 µL of the dilution was added to a 6 µL of RdRp containing RNAse inhibitor for preincubation (30 minutes at room temperature with slow shaking). Reaction was started by addition of 2 µL of the substrate mix containing RNA duplex and ATP substrate. Final concentration of DMSO was 1% in all of reactions (reference compound 6-Chloropurine-ribose-5'- triphosphate – 0% DMSO). After enzymatic reactions, 10 µL of Eu-labeled anti-Dig antibody (BPS, diluted 1:600 with 1x detection buffer) and Dye-labeled acceptor (diluted 1:200 with 1x detection buffer) added to the reaction mix. After brief shaking, plate was incubated for 20 min. In 20 minutes, the samples were measured in microplate reader (Tecan M1000, Tecan). Data Analysis [00459] Enzyme activity assays were performed in duplicates at each concentration. The TR-FRET data were analyzed and compared. The data were analyzed using the computer software, Graphpad Prism. In the absence of the compound, the intensity (Ce) in each data set was defined as 100 % activity. In the absence of enzyme, the intensity (C
0) in each data set was defined as 0 % activity. The percent activity in the presence of each compound was calculated according to the following equation: % activity = (C-C
0)/(C
e-C
0), where C = the TR-FRET intensity in the presence of the compound. The % activity as a function of compound concentration was then plotted and fitted using non-linear regression analysis of Sigmoidal dose-response curve generated with the equation Y=B+(T-B)/1+10
((LogEC 50 -X)×Hill Slope), where Y = percent activity, B = minimum percent activity, T = maximum percent activity, X = logarithm of compound and Hill Slope = slope factor or Hill coefficient. The IC
50 value was determined as the concentration causing half-maximal percent activity. [00460] Table 5 summarizes the results for select exemplary triphosphate analogs, plus negative control GS-441524 (parent nucleoside analog), and positive control compounds GS-443902 (Mackman, RL, et al, J Med Chem 2023, 66 (17), 11701-11717; DOI: 10.1021/acs.jmedchem.3c00750) and 6-chloropurine- ribose-5'-triphosphate. As may be seen from these results, intermediate amides derived from ester cleavage of the compounds of the invention retain inhibitory activity similar to or better than GS-441524, indicating that these amides have the potential to exert antiviral activity directly, without requiring metabolic conversion to GS-441524 in vivo.
