TECHNICAL FIELD OF THE INVENTION

[0002] The present invention features modulators of Cystic Fibrosis Transmembrane

Conductance Regulator (CFTR), pharmaceutical compositions, methods of treatment, and kits thereof.

BACKGROUND OF THE INVENTION

[0003] Cystic fibrosis (CF) is a recessive genetic disease that affects approximately 30,000 children and adults in the United States and approximately 30,000 children and adults in Europe. Despite progress in the treatment of CF, there is no cure.

[0004] In patients with CF, mutations in CFTR endogenously expressed in respiratory epithelia leads to reduced apical anion secretion causing an imbalance in ion and fluid transport. The resulting decrease in anion transport contributes to enhanced mucus accumulation in the lung and the accompanying microbial infections that ultimately cause death in CF patients. In addition to respiratory disease, CF patients typically suffer from gastrointestinal problems and pancreatic insufficiency that, if left untreated, results in death. In addition, the majority of males with cystic fibrosis are infertile and fertility is decreased among females with cystic fibrosis. In contrast to the severe effects of two copies of the CF associated gene, individuals with a single copy of the CF associated gene exhibit increased resistance to cholera and to dehydration resulting from diarrhea - perhaps explaining the relatively high frequency of the CF gene within the population.

[0005] Sequence analysis of the CFTR gene of CF chromosomes has revealed a variety of disease causing mutations (Cutting, G. R. et al. (1990) Nature 346:366-369; Dean, M. et al. (1990) Cell 61:863:870; and erem, B-S. et al. (1989) Science 245:1073-1080; Kerem, B-S et al. (1990) Proc. Natl. Acad. Sci. USA 87:8447-8451). To date, greater than 1000 disease causing mutations in the CF gene have been identified (http://cftr2.org). The most prevalent mutation is a deletion of phenylalanine at position 508 of the CFTR amino acid sequence, and is commonly referred to as F508del. This mutation occurs in approximately 70% of the cases of cystic fibrosis and is associated with a severe disease.

[0006] The deletion of residue 508 in F508del prevents the nascent protein from folding correctly. This results in the inability of the mutant protein to exit the ER, and traffic to the plasma membrane. As a result, the number of channels present in the membrane is far less than observed in cells expressing wild-type CFTR. In addition to impaired trafficking, the mutation results in defective channel gating. Together, the reduced number of channels in the membrane and the defective gating lead to reduced anion transport across epithelia leading to defective ion and fluid transport. (Quinton, P. M. (1990), FASEB J. 4: 2709-2727). Studies have shown, however, that the reduced numbers of F508del in the membrane are functional, albeit less than wild-type CFTR. (Dalemans et al. (1991), Nature Lond. 354: 526-528; Denning et al., supra; Pasyk and Foskett (1995), J. Cell. Biochem. 270: 12347-50). In addition to F508del, other disease causing mutations in CFTR that result in defective trafficking, synthesis, and/or channel gating could be up- or down-regulated to alter anion secretion and modify disease progression and/or severity.

[0007] Accordingly, there is a need for novel treatments of CFTR mediated diseases.

BRIEF DESCRIPTION OF DRAWINGS

[0010] Figure 1 discloses a list of CFTR mutations by name, protein name, and legacy name that in one aspect of the invention a patient may possess and be treatable by the compounds and compositions of the present invention. DETAILED DESCRIPTION OF THE INVENTION

[0011] Definitions

[0012] As used herein, "CFTR" stands for cystic fibrosis transmembrane conductance regulator.

[0013] As used herein, "mutations" can refer to mutations in the CFTR gene or the CFTR protein. A "CFTR mutation" refers to a mutation in the CFTR gene, and a "CFTR mutation" refers to a mutation in the CFTR protein. A genetic defect or mutation, or a change in the nucleotides in a gene in general results in a mutation in the CFTR protein translated from that gene.

[0014] As used herein, a "F508del mutaion" or "F508del" is a specific mutation within the CFTR protein. The mutation is a deletion of the three nucleotides that comprise the codon for amino acid phenylalanine at position 508, resulting in CFTR protein that lacks this phenylalanine residue.

[0015] The term "CFTR gating mutation" as used herein means a CFTR mutation that results in the production of a CFTR protein for which the predominant defect is a low channel open probability compared to normal CFTR (Van Goor, F., Hadida S. and Grootenhuis P.,

"Pharmacological Rescue of Mutant CFTR function for the Treatment of Cystic Fibrosis", Top. Med. Chem. 3: 91-120 (2008)). Gating mutations include, but are not limited to, G551D, G178R, S549N, S549R, G551S, G970R, G1244E, S 1251N. S 1255P, and G1349D.

[0017] As used herein, a patient who is "heterozygous" for a particular mutation, e.g.

F508del, has this mutation on one allele, and a different mutation on the other allele.

[0018] As used herein, the term "modulator" refers to a compound that increases the activity of a biological compound such as a protein. For example, a CFTR modulator is a compound that increases the activity of CFTR. The increase in activity resulting from a CFTR modulator may be through a corrector mechanism or a potentiator mechanism as described below.

[0019] As used herein, the term "CFTR corrector" refers to a compound that increases the amount of functional CFTR protein to the cell surface, resulting in enhanced ion transport. ^' [0020] As used herein, the term "CFTR potentiator" refers to a compound that increases the channel activity of CFTR protein located at the cell surface, resulting in enhanced ion transport.

[0021] As used herein, the term "inducing," as in inducing CFTR activity, refers to increasing CFTR activity, whether by the corrector, potentiator, or other mechanism.

[0022] As used herein, the term "active pharmaceutical ingredient" or "API" refers to a biologically active compound.

[0023] A "patient," "subject" or "individual" are used interchangeably and refer to either a human or non-human animal. The term includes mammals such as humans.

[0024] The terms "effective dose" or "effective amount" are used interchangeably herein and refer to that amount that produces the desired effect for which it is administered (e.g., improvement in CF or a symptom of CF or lessening the severity of CF or a symptom of CF). The exact amount will depend on the purpose of the treatment, and will be ascertainable by one skilled in the art using known techniques (see, e.g., Lloyd (1999) The Art, Science and

Technology of Pharmaceutical Compounding).

[0025] As used herein, the terms "treatment," "treating," and the like generally mean the improvement of CF or its symptoms or lessening the severity of CF or its symptoms in a subject. 'Treatment," as used herein, includes, but is not limited to, the following: increased growth of the subject, increased weight gain, reduction of mucus in the lungs, improved pancreatic and/or liver function, reduced cases of chest infections, and/or reduced instances of coughing or shortness of breath. Improvements in or lessening the severity of any of these conditions can be readily assessed according to standard methods and techniques known in the art.

[0026] As used herein, the term "in combination with" when referring to two or more compounds or agents means that the order of administration includes the compounds or agents being administered prior to, concurrent with, or subsequent to each other to the patient.

[0027] As used herein, the phrase "optionally substituted" is used interchangeably with the phrase "substituted or unsubstituted."

[0028] As described herein, compounds within the compositions of the invention can optionally be substituted with one or more substituents, such as are illustrated generally above, or as exemplified by particular classes, subclasses, and species of the invention (such as the compounds listed in Table 1). As described herein in formulae I-Id-ii , the variables R|-R»in formulae I-Id-ii encompass specific groups, such as, for example, alky], alkenyl, alkynyl, alkoxy, heteroaryl, heterocyclic, cycloalkyl, and aryl, etc. Unless otherwise noted, each of the specific groups for the variables R1-R can be optionally substituted with one or more group selected from halo, phospho, OH, cycloalkyl, heterocycloalkyl, aryl, heteroaryl, fluoroalkyl, alkyl, alkenyl, alkynyl, nitro, CN, hydroxyl, and (Cl-C9alkylene)-E wherein up to 4 C¾ units are independently replaced with O, S, SO2, SO, CO, NH, iV-alkyl, iV-alkenyl, or iV-alkynyl, and E is H, aryl, cycloalkyl, heterocycloalkyl, heteroaryl, alkoxy.CN, or CF3, further wherein each of the aryl, cycloalkyl, heterocycloalkyl, and heteroaryl is optionally substituted with one or more group selected from halo, alkyl, amino, CN, alkenyl, alkynyl, and alkoxy.

[0029] As one of ordinary skill in the art will recognize, combinations of substituents envisioned by this invention are those combinations that result in the formation of stable or chemically feasible compounds. The term "stable", as used herein, refers to compounds that are not substantially altered when subjected to conditions to allow for their production, detection, and preferably their recovery, purification, and use for one or more of the purposes disclosed herein. In some embodiments, a stable compound or chemically feasible compound is one that is not substantially altered when kept at a temperature of 40°C or less, in the absence of moisture or other chemically reactive conditions, for at least a week. When two alkoxy groups are bound to the same atom or adjacent atoms, the two alkoxy groups can form a ring together with the atom(s) to which they are bound.

[0030] As disclosed herein, substituents or variables (such as R and R1-R in formula I-Id-ii) can be selected from more than one specific group. To the extent that one specific group for a variable may include or overlap with another specific group for the same variable, the narrower specific group is provisoed out from the broader specific group. In other words, double inclusion cannot exist.

[0031] In general, the term "substituted," whether preceded by the term "optionally" or not, refers to the replacement of hydrogen radicals in a given structure with the radical of a specified substituent. Specific substituents are described above in the definitions and below in the description of compounds and examples thereof. Unless otherwise indicated, an optionally substituted group can have a substituent at each substitutable position of the group, and when more than one position in any given structure can be substituted with mote than one substituent selected from a specified group, the substituent can be either the same or different at every position. As one of ordinary skill in the art will recognize, combinations of substituents envisioned by this invention are those combinations that result in the formation of stable or chemically feasible compounds.

For example, -CH2CH2CH₂SH is within the definition of C1-C9 alkylene-R4 wherein up to four CH₂ units are independently replaced by O, CO, S, SO, S0₂, or NR because the CH₂ unit of the terminal methyl group has been replaced by S. The analogous applies to such definitions as - CH2CH2OH, -CH2CH₂CN, or-CH₂CH₂NH₂.

[0057] Unless otherwise stated, structures depicted herein are also meant to include all isomeric (e.g., enantiomeric, diastereomeric, and geometric (or conformational)) forms of the structure; for example, the R and S configurations for each asymmetric center, (Z) and (E) double bond isomers, and (Z) and (E) conformational isomers. Therefore, single stereochemical isomers as well as enantiomeric, diastereomeric, and geometric (or conformational) mixtures of the present compounds are within the scope of the invention. Where the enantiomers of a racemic mixture have been separated, but the absolute chemistry has not yet been determined, the compound's structure is depicted with a wavy line. [0058] Unless otherwise stated, all tautomeric forms of the compounds of the invention are within the scope of the invention. Thus, included within the scope of the invention are tautomers of compounds of formulas I to Id-ii.

[0059] To the extent that a definition in the present application differs from any definition in an application incorporated by reference, the definition in the present application supercedes.

[0060] CFTR is a cAMP/ATP-mediated anion channel that is expressed in a variety of cells types, including absorptive and secretory epithelia cells, where it regulates anion flux across the membrane, as well as the activity of other ion channels and proteins. In epithelia cells, normal functioning of CFTR is critical for the maintenance of electrolyte transport throughout the body, including respiratory and digestive tissue. CFTR is composed of approximately 1480 amino acids that encode a protein made up of a tandem repeat of transmembrane domains, each containing six transmembrane helices and a nucleotide binding domain. The two transmembrane domains are linked by a large, polar, regulatory (R)-domain with multiple phosphorylation sites that regulate channel activity and cellular trafficking.

[0061] In patients with cystic fibrosis, mutations in endogenously expressed CFTR lead to reduced apical anion secretion causing an imbalance in ion and fluid transport. The resulting decrease in anion transport contributes to enhanced mucus accumulation in the lung and the accompanying microbial infections that ultimately cause death in CF patients. In addition to respiratory disease, CF patients typically suffer from gastrointestinal problems and pancreatic insufficiency that, if left untreated, results in death. In addition, the majority of males with cystic fibrosis are infertile and fertility is decreased among females with cystic fibrosis. In contrast to the severe effects of two copies of the CF associated gene, individuals with a single copy of the CF associated gene exhibit increased resistance to cholera and to dehydration resulting from diarrhea-perhaps explaining the relatively high frequency of the CF gene within the population.

[0062] Sequence analysis of the CFTR gene of CF chromosomes has revealed a variety of disease-causing mutations (Cutting, G. R. et al. (1990) Nature 346:366-369; Dean, M. et al. (1990) Cell 61:863:870; and Kerem, B-S. et al. (1989) Science 245: 1073-1080; Kerem, B-S et al. (1990) Proc. Natl. Acad. Sci. USA 87:8447-8451). To date, greater than 1000 disease-causing mutations in the CF gene have been identified as reported by the scientific and medical literature. The most prevalent mutation is a deletion of phenylalanine at position 508 of the CFTR amino acid sequence, and is commonly referred to as FS08del. This mutation occurs in approximately 70 percent of the cases of cystic fibrosis and is associated with a severe disease. A more complete list of identified mutations can be found at www.cftr2.org.

[0063] These elements work together to achieve directional transport across the epithelium via their selective expression and localization within the cell. Chloride absorption takes place by the coordinated activity of ENaC and CFTR present on the apical membrane and the Na⁺-K⁺- ATPase pump and CI- channels expressed on the basolateral surface of the cell. Secondary active transport of chloride from the luminal side leads to the accumulation of intracellular chloride, which can then passively leave the cell via CI^' channels, resulting in a vectorial transport. Arrangement of Na⁺/2C17K⁺ co-transporter, Na⁺-K⁺-ATPase pump and the basolateral membrane K⁺ channels on the basolateral surface and CFTR on the luminal side coordinate the secretion of chloride via CFTR on the luminal side. Because water is probably never actively transported itself, its flow across epithelia depends on tiny transepithelial osmotic gradients generated by the bulk flow of sodium and chloride.

An isotope-labelled compound of formulas I to Id-ii can be used in a number of beneficial ways. For example, an isotope-labelled compound of formula I to In-i into which, for example, a radioisotope, such as ³H or ^l C, has been incorporated is suitable for medicament and/or substrate tissue distribution assays. These radioisotopes, i.e. tritium (³H) and carbon- 14 (^l4C), are particularly preferred owing to simple preparation and excellent detectability. Incorporation of heavier isotopes, for example deuterium ( H), into a compound of formulas I to Id-ii has therapeutic advantages owing to the higher metabolic stability of this isotope-labelled compound. Higher metabolic stability translates directly into an increased in vivo half-life or lower dosages, which under most circumstances would represent a preferred embodiment of the present invention. An isotope-labelled compound of formulas I to Id-ii can usually be prepared by carrying out the procedures disclosed in the synthesis schemes and the related description, in the example part and in the preparation part in the present text, replacing a non-isotope-labelled reactant by a readily available isotope-labelled reactant.

[00521] Deuterium (²H) can also be incorporated into a compound of formulas I to Id-ii for the purpose in order to manipulate the oxidative metabolism of the compound by way of the primary kinetic isotope effect. The primary kinetic isotope effect is a change of the rate for a chemical reaction that results from exchange of isotopic nuclei, which in turn is caused by the change in ground state energies necessary for covalent bond formation after this isotopic exchange.

Exchange of a heavier isotope usually results in a lowering of the ground state energy for a chemical bond and thus causes a reduction in the rate-limiting bond breakage. If the bond breakage occurs in or in the vicinity of a saddle-point region along the coordinate of a multi- product reaction, the product distribution ratios can be altered substantially. For explanation: if deuterium is bonded to a carbon atom at a non-exchangeable position, rate differences of kMko= 2-7 are typical. If this rate difference is successfully applied to a compound of formulas I to Id-ii that is susceptible to oxidation, the profile of this compound in vivo can be drastically modified and result in improved pharmacokinetic properties. For a further discussion, see S. L. Harbeson and R. D. Tung, Deuterium In Drug Discovery and Development, Ann. Rep. Med. Chem. 2011, 46, 403-417, incorporated in its entirety herein by reference.

[00522] When discovering and developing therapeutic agents, the person skilled in the art attempts to optimise pharmacokinetic parameters while retaining desirable in vitro properties. It is reasonable to assume that many compounds with poor pharmacokinetic profiles are susceptible to oxidative metabolism. In vitro liver microsomal assays currently available provide valuable information on the course of oxidative metabolism of this type, which in turn permits the rational design of deuterated compounds of formulas I to Id-ii with improved stability through resistance to such oxidative metabolism. Significant improvements in the pharmacokinetic profiles of compounds of formulas I to Id-ii are thereby obtained, and can be expressed quantitatively in terms of increases in the in vivo half-life (t^), concentration at maximum therapeutic effect ( nax), area under the dose response curve (AUC), and bioavailability; and in terms of reduced clearance, dose and materials costs.

[00523] The following is intended to illustrate the above: a compound of formulas I to Id-ii which has multiple potential sites of attack for oxidative metabolism, for example benzylic hydrogen atoms and hydrogen atoms bonded to a nitrogen atom, is prepared as a series of analogues in which various combinations of hydrogen atoms are replaced by deuterium atoms, so that some, most or all of these hydrogen atoms have been replaced by deuterium atoms. Half-life determinations enable favourable and accurate determination of the extent to which the improvement in resistance to oxidative metabolism has improved. In this way, it is determined that the half-life of the parent compound can be extended by up to 100% as the result of deuterium-hydrogen exchange of this type.

[00524] Deuterium-hydrogen exchange in a compound of formulas I to Id-ii can also be used to achieve a favorable modification of the metabolite spectrum of the starting compound in order to diminish or eliminate undesired toxic metabolites. For example, if a toxic metabolite arises through oxidative carbon-hydrogen (C-H) bond cleavage, it can reasonably be assumed that the deuterated analogue will greatly diminish or eliminate production of the unwanted metabolite, even if the particular oxidation is not a rate-determining step. Further information on the state of the art with respect to deuterium-hydrogen exchange may be found, for example in Hanzlik et al., J. Org. Chem. 55, 3992-3997, 1990, Reider et al., J. Org. Chem. 52, 3326-3334, 1987, Foster, Adv. Drug Res. 14, 1-40, 1985, Gillette et al, Biochemistry 33(10) 2927-2937, 1994, and Jarman et al. Carcinogenesis 16(4), 683-688, 1993.

[001314] In certain embodiments, the composition of the present invention is useful for treating, lessening the severity of, or symptomatically treating cystic fibrosis in patients who exhibit residual CFTR activity in the apical membrane of respiratory and non-respiratory epithelia. The presence of residual CFTR activity at the epithelial surface can be readily detected using methods known in the art, e.g., standard electrophysiological, biochemical, or histochemical techniques. Such methods identify CFTR activity using in vivo or ex vivo electrophysiological techniques, measurement of sweat or salivary CI^" concentrations, or ex vivo biochemical or histochemical techniques to monitor cell surface density. Using such methods, residual CFTR activity can be readily detected in patients heterozygous or homozygous for a variety of different mutations, including patients homozygous or heterozygous for the most common mutation, F508del, as well as other mutations such as the GSS1D mutation, or the Rl 17H mutation. In certain embodiments, compositions of the present invention are useful for treating, lessening the severity of, or symptomatically treating cystic fibrosis in patients who exhibit little to no residual CFTR activity. In certain embodiments, compositions of the present invention are useful for treating, lessening the severity of, br symptomatically treating cystic fibrosis in patients who exhibit little to no residual CFTR activity in the apical membrane of respiratory epithelia.

[001315] In another embodiment, the compositions of the present invention are useful for treating or lessening the severity of cystic fibrosis in patients who exhibit residual CFTR activity using pharmacological methods, hi another embodiment, the compositions of the present invention are useful for treating or lessening the severity of cystic fibrosis in patients who have residual CFTR activity using gene therapy. Such methods increase the amount of CFTR present at the cell surface, thereby inducing a hitherto absent CFTR activity in a patient or augmenting the existing level of residual CFTR activity in a patient.

[001316] In one embodiment, the compositions of the present invention are useful for treating or lessening the severity of cystic fibrosis in patients within certain genotypes exhibiting residual CFTR activity, e.g., Class I mutations (not synthesized), class Π mutation (misfolding), class HI mutations (impaired regulation or gating), class IV mutations (altered conductance), or class V mutations (reduced synthesis).

[001317] In one embodiment, compositions of the present invention are useful for treating, lessening the severity of, or symptomatically treating cystic fibrosis in patients within certain clinical phenotypes, e.g., a moderate to mild clinical phenotype that typically correlates with the amount of residual CFTR activity in the apical membrane of epithelia. Such phenotypes include patients exhibiting pancreatic sufficiency.

[001318] In one embodiment, the compositions of the present invention are useful for treating, lessening the severity of, or symptomatically treating patients diagnosed with pancreatic sufficiency, idiopathic pancreatitis and congenital bilateral absence of the vas deferens, or mild lung disease wherein the patient exhibits residual CFTR activity.

[001319] In one embodiment, the compositions of the present invention are useful for treating, lessening the severity of, or symptomatically treating patients diagnosed with pancreatic sufficiency, idiopathic pancreatitis and congenital bilateral absence of the vas deferens, or. mild lung disease wherein the patient has wild type CFTR.

[001320] In addition to cystic fibrosis, modulation of CFTR activity may be beneficial for other diseases: not directly caused by mutations in CFTR, such as secretory diseases and other protein folding diseases mediated by CFTR. These include, but are not limited to, chronic obstructive pulmonary disease (COPD), dry eye disease, and Sjdgren's . Syndrome. COPD is characterized by airflow limitation that is progressive and not fully reversible. The airflow limitation is due to mucus hypersecretion, emphysema, and bronchiolitis. Activators of mutant or wild-type CFTR offer a potential treatment of mucus hypersecretion and impaired mucociliary clearance that is common in-COPD. Specifically, increasing anion secretion across CFTR may facilitate fluid transport into the airway surface liquid to hydrate the mucus and optimized periciliary fluid viscosity. This would lead to enhanced mucociliary clearance and a reduction in the symptoms associated with COPD. Dry eye disease is characterized by a decrease in tear aqueous production and abnormal tear film lipid, protein and mucin profiles.' There are many causes of dry eye, some of which include age, Lasik eye surgery, arthritis, medications, chemical/thermal burns, allergies, and diseases, such as cystic fibrosis and Sj6grens's syndrome. Increasing anion secretion via CFTR would enhance fluid transport from the corneal endothelial cells and secretory glands surrounding the eye to increase corneal hydration. This would help to alleviate the symptoms associated with dry eye disease. Sjogrens's syndrome is an autoimmune disease in which the immune system attacks moisture-producing glands throughout the body, including the eye, mouth, skin, respiratory tissue, liver, vagina, and gut. Symptoms, include, dry eye, mouth, and vagina, as well as lung disease. The disease is also associated with rheumatoid arthritis, systemic lupus, systemic sclerosis, and polymypositis dermatomyositis. Defective protein trafficking is believed to cause the disease, for which treatment options are limited. Augmenters or inducers of CFTR activity may hydrate the various organs afflicted by the disease and help to elevate the associated symptoms.

[001321] In one embodiment, the invention relates to a method of augmenting or inducing anion channel activity in vitro or in vivo, comprising contacting the channel with a composition of the present invention. In another embodiment, the anion channel is a chloride channel or a bicarbonate channel. In another embodiment, the anion channel is a chloride channel.

[001322] The exact amount required will vary from subject to subject, depending on the species,

age, and general condition of the subject, the severity of the infection, the particular agent, its mode of administration, and the like. The compounds of the invention are preferably formulated in dosage unit form for ease of admimstration and uniformity of dosage. The expression "dosage unit form" as used herein refers to a physically discrete unit of agent appropriate for the patient to be treated. It will be understood, however, that the total daily usage of the compounds and compositions of the invention will be decided b the attending physician within the scope of sound medical judgment. The specific effective dose level for any particular patient or organism will depend upon a variety of factors including the disorder being treated and the severity of the disorder, the activity of the specific compound employed; the specific composition employed; the age, body weight, general health, sex and diet of the patient; the time of administration, route of administration, and rate of excretion of the specific compound employed; the duration of the treatment; drugs used in combination or coincidental with the specific compound employed, and like factors well known in the medical arts. The term "patient", as used herein, means an animal, preferably a mammal, and most preferably a human. [001323] In recent years a number of attempts have been made to treat cystic fibrosis using gene therapy. Gene therapy is the insertion, alteration, or removal of genes within an individual's cells and biological tissues to treat disease. It is a technique for correcting defective genes that are responsible for disease development. The most common form of gene therapy involves the insertion of functional genes into an unspecified genomic location in order to replace a mutated gene, but other forms involve directly correcting the mutation or modifying normal gene that enables a viral infection. Although the technology is still in its infancy, it has been used with some success.

[001324] Cystic fibrosis is a good candidate for gene therapy as it is primarily caused by mutations in a single gene. A normal copy of the gene could be delivered to patients via topical delivery to the lung, not requiring invasive techniques or surgery. A gene complementation approach would aslo directly target the cause of the disease and could correct many aspects of die complex lung pathology.

[001325] Soon after the cloning of the CFTR gene, proof-of-principle was established when the Cl-conductance defect was corrected after delivery of a functional copy of human wild-type CFTR DNA to cells isolated from cystic fibrosis patients. To date, a number of trials for cystic fibrosis gene therapy have been tested in humans. These early studies were concerned mainly with safety issues.

[001571] NaH (60%, 62 mg, 1.5 mmol) was added to a mixture of methyl 4-chloro-lH- pyrrolo[3,2-c]pyridiiie-2-carboxylate (250. mg, 1.19 mmol) and JV.iV-dimeraylformaiiiide (5 mL) at 0 °C. The mixture was allowed to stir for 15 min at 0 °C before a solution of 2- (chloromemyl l,3,5-trimethyl-benzene (260. mg, 1.54 mmol) in ΜΛΓ-dimethylformamide (1 mL) was added dropwise. The mixture was allowed to stir for 1Η at room temperature, then 4h at 60 °C. The mixture was partitioned between IN HQ and ethyl acetate. The layers were separated and the aqueous layer was extracted with ethyl acetate (3x). The combined organic layers were washed with brine (2x), dried over magnesium sulfate, filtered and concentrated under reduced pressure. The clear residue was subjected to silica gel column chromatography (0-20% ethyl acetate hexanes) to give methyl 4-chloro- 1 -[(2,4,6- trimemylphenyl)n.etoyl]py^ (370 mg, 91 %). ESI-MS m/z calc.

The mixture was concentrated to give methyl 4- memoxy-l-[(2,4,6-trimemylphenyl)memyl]pyirolo[3,2-c]pyri (56 mg, 15%) as a white solid. ESI-MS m/z calc. 338.2, found 339.4 (M+l)⁺; Retention time: 0.64 min (1 min run).

[001574] Step 3: 4-methoxy-l-[(2^6-trimethyIphenyl)methyl]pyrrolo[3^-i;]pyridine-2- carboxylic acid

[001575] Lithium hydroxide (160 μL· of 2.0 M, 0.32 mmol) was added to a mixture of methyl 4-memoxy-l-[(2,4j6-trimethylphenyl)memyl]py-Tolo[3,2-c]pyri(iine-2< (50. mg, 0.15 mmol) and EtOH (1 mL) at room temperature. The mixture was allowed to stir at room temperature overnight. The mixture was concentrated and the residue was partitioned between IN HC1 and CH₂C1₂. The layers were separated and the aqueous layer, was extracted with CH₂C1₂ (3x). The combined prganics were washed with brine, dried over magnesium sulfate, filtered and concentrated. The residue was taken up in A^dimemylfonnamide and subjected to preparatory-HPLC (10-99% acetonitrile water with 0.05 mM HC1) to give 4-methoxy-l -[(2,4,6- aimemylphenyl)irjemyl]pyiTolo[3,2-c]pyridine-2-carboxylic acid (39 mg, 81%) as a white solid.

The mixture was heated to 90 °C for 3h. The reaction mixture was filtered and then purified using a reverse phase HPLC-MS method using a Luna C 18 column (50 x 21.2 mm, 5 μιη particle size) sold by Phenomenex (pn: OOB-4252-P0-AX), and a dual gradient run from 1 -99% mobile phase B over 15.0 minutes.

[001832] To a solution of fert-butyl 1-methylisoindoline-l-carboxylate (1.5 g, 6.4 mmol) in acetonitrile (75.00 mL) was added 2-(chloromethyl)-l,3,5-trimethyl -benzene (1.084 g, 6.429 mmol) and cesium carbonate (4.190 g, 12.86 mmol). The mixture was heated at 90 °C overnight, and then partitioned between ethyl acetate and water. The aqueous layer was extracted with ethyl acetate. The combined organic layers were washed with brine, dried over magnesium sulate, filtered, and concentrated to dryness. The crude material was purified by silica column chromatography utilizing a gradient of 0-5% ethyl acetate in hexanes to provide ferf-butyl 1- methyl-2-[(2,4,6-trimethylphenyl)methyl]isoindoline-l-carboxylate. This material was then dissolved in dioxane (3.2 mL) and hydrochloric acid in dioxane (5 mL of 4 M, 20.00 mmol) was added to the mixture. The mixture was stirred for 16 hours at room temperature. The mixture was then stirred at 70 °C for 1 hour. The reaction mixture was cooled to room temperature, the precipitate was filtered and washed with dioxane to give an off-white solid. l-methyl-2-[(2,4,6- trimethylphenyl)methyl]isoindoline-l-carboxylic acid (0.98 g, 3.2 mmol, 49%) ESI-MS m/z calc. 309.17288, found 310.5 (M+l)⁺; Retention time: 1.18 minutes (3 min run).

[002055] Step 1: 2-Methoxypyridine-3-sulfonamide

[002056] 2-Chloropyridine-3-sulfonyl chloride (5.00 g, 23.6 mmol) was dissolved in ammonia in methanol (16.8 mL of 7 M, 117.9 mmol) and the reaction mixture was stirred for 30 minutes. The reaction mixture was concentrated under reduced pressure and dissolved in sodium methoxide (24.9 mL of 25 %w/v, 1 15.1 mmol) and heated to 60 °C over 2 days. The reaction mixture was evaporated and the residue was partitioned between ethyl acetate and IN HC1. The organics were separated, washed with brine, dried over sodium sulfate and concentrated under reduced pressure. The crude material was purified by silica gel column chromatography eluting with 0-100% ethyl acetate in hexanes to give 2-methoxypyridine-3- sulfonamide (3.12 g, 70%) ESI-MS m/z calc. 188.02556, found 189.0 (M+l)⁺; Retention time: 0.23 minutes

[002057] Step 2: 2,6-mchloro-W-[(2-memoxy-3-pyridyl)sulfonyl]pyridine-3-carboxamide

[002058] A mixture of 2,6-dichloropyridine-3-carboxylic acid (2.00 g, 10.4 mmol), thionyl chloride (7.45 g, 4.56 mL, 62.5 mmol), and DMF (0.1 mL) was stirred at 45 °C for 5 hours. The reaction was concentrated under reduced pressure, dissolved in dichloromethane (5.30 mL) and slowly added to a solution of 2-methoxypyridine-3-sulfonamide (1.96 g, 10.4 mmol) and triethylamine (3.16 g, 4.36 mL, 31.3 mmol) in dichloromethane (5.30 mL) cooled in an ice bath. The reaction mixture was stirred overnight, then diluted with dichloromethane and washed with 1 M HC1 (20 mL x 1), water (20 mL), dried over sodium sulfate, and evaporated under reduced pressure. The residue was purified by silica gel column chromatography (0-5 % methanol in dichloromethane). The resulting solid was dissolved in dichloromethane and washed with sodium bicarbonate (~ pH 5), the organic layers were dried over sodium sulfate and evaporated under reduced pressure to give 2,6-dichloro-N-[(2-methoxy-3- pyridyl)sulfonyl]pyridine-3-carboxamide (3.50 g, 93%) ESI-MS m/z calc. 360.9691, found 362.0 (M+l)⁺; Retention time: 0.46 minutes.

[002059] Step 3: 2,6-dichloro-.V-[(2-oxo- 1 H-pyridin-3-yl)sulfonyI]pyridine-3-carboxainide

[002060] A mixture of 2,6-dichloro- V-[(2-methoxy-3-pyridyl)sulfonyl]pyridine-3- carboxamide (0.76 g, 2.10 mmol) and HC1 (5.25 mL of 4 M in dioxane, 21.0 mmol) in dioxane (5 mL) was stirred at 90 °C for 90 minutes. The solvent was evaporated under reduced pressure to give 2,6-dichloro-A^-((2-oxo-l,2-dihydropyridin-3-yl)sulfonyl)nicotinamide (0.72 g, 99%) as a tan solid.

[002061] Step 4: 6-chloro- -[(2-oxo- ltf-pyridin-3-yl)sulfonyl]-2-[(4S)-2,2,4- trimethy!pyrrolidin- 1 -yl]pyridine-3-carboxamide

[002062] To 2,6-dichloro-/V-[(2-oxo- 1 / -pyridin-3-yl)sulfony l]pyridine-3-carboxarnide (HC1 salt) (4.04 g, 10.5 mmol), (4S)-2,2,4-trimethylpyrrolidine (HC1 salt) (2.36 g, 15.8 mmol), and K2CO3 (7.26 g, 52.5 mmol) was added DMSO (8.86 mL) and the reaction mixture was heated at 120 °C for 24 h. The reaction mixture was diluted with ethyl acetate and the residual potassium carbonate was filtered. The organics were washed with 0.1 M aqueous HQ (150 mL). The pH of aqueous layer was brought to 5 by the addition of aqueous HC1, and then washed with ethyl acetate. The combined organic layers were washed with brine, dried over sodium sulfate and concentrated under reduced pressure to give 6-chloro- -[(2-oxo-lH-pyridin-3-yl)sulfonyl]- 2-[(4^-2,2,4-trimethylpyrrolidin-l-yl]pyridine-3-carboxamicte (4.15 g, 94%).

[002366] Step 1: Methyl-2,4-dimethyl-4-nitro-pentanoate

THF (4.5 L) was added to a 20 L glass reactor and stirred under an atmosphere of nitrogen at room temperature. 2-Nitropropane (1.5 kg) and DBU (1.282 kg, 0.5 equiv.) were then charged to the reactor (immediate yellow color observed) and the jacket temperature was increased to 50 °C. Once the reactor contents were close to 50 °C, methyl methacrylate (1.854 kg, 1.1 equiv.) was added slowly over 100 minutes. The reaction temperature was maintained at or close to 50 °C with reaction completion reached at 21 h. During the course of the reaction, a color change from yellow to deep green was observed. The reaction mixture was concentrated in vacuo then transferred back to the reactor and diluted with MTBE (14 L). 2 M HC1 (7.5 L) was added and this was stirred for 5 minutes then allowed to settle. Two clear layers were visible - a lower yellow aqueous phase and an upper green organic phase. The aqueous was removed and the organic was stirred again with 2 M HC1 (3 L). After separation, the HCI washes were recombined and stirred with MTBE (3 L) for 5 minutes. The aqueous was removed and all of the organics were combined in the reactor and stirred with water (3 L) for 5 minutes. After separation, the organics were concentrated in vacuo to afford a cloudy green mobile oilm which was dried with MgS0 and filtered to afford racemic meihyl-2,4-dimethyl-4~nitro-pentanoate (3.16 kg) as a clear green mobile oil (99% yield).

To this was added 3.5 L lipase (palatase from Novozymes) and stirred at 34 °C for -43 h. The pH of the reaction was maintained at pH 6.5 by pH Stat dosing ₂C0₃ (aq. Soln). The reaction mixture was extracted with MTBE (2 5 vol, 1 x 2 vol). The combined MTBE layers were then washed with 2 M Na2C0₃ (4 x 2.5 vol), water (3 vol) and brine (3 vol). The product was concentrated down to -10 L in the reactor by distilling off the MTBE and transferred to a large rotary evaporator for final concentration to afford methyl (2?)-2,4-dimethyl-4-nitro-pentanoate as a mobile yellow oil (3072.2 g, 44% yield).

Stirring was commenced at 900 rpm and the reactor flushed with H2 and maintained at ~2.5 bar. After 5 hours, the reaction mixture was filtered to remove Raney nickel and solid cake rinsed with ethanol (3.5 L, 2 vol). The ethanolic solution of product was concentrated in vacuo to reduce to a minimum volume of ethanol (- 1.5 volumes), then heptane (2.5 L) was added and the suspension concentrated again to -1.5 volumes. This was repeated a further 3 times, then the resulting suspension was cooled to 0-5 °C and filtered under suction and washed with heptane (2.5 L). The product was dried on the filter under vacuum for 20 minutes then transferred to drying trays and dried in a vacuum oven at 40 °C overnight (with N2 bleed).

[002404] Solid potassium carbonate (90 mg, 0.65 mmol) was added to a suspension of 2,2-dimethylpyrrolidin-3-one (49 mg, 0.32 mmol) in DMSO (250 μΐ.), followed by -[(6- amino-2^yridyl)sulfonyl]-2-fluoro-6-(3-fluoro-5-i5obutoxy-phenyl)pyridine-3-carboxamide (HC1 salt) (50 mg, 0.1 1 mmol). The reaction mixture was stirred at 150 °C for 3 hours. The reaction mixture was purified using a reverse phase HPLC method using a Luna C18 (2) column (50 x 21.2 mm, 5 μπι particle size) and a dual gradient run from 10-99% mobile phase B over 15.0 minutes (mobile phase A = water (5 mM HC1), mobile phase B = acetonitrile).

Compounds

Membrane potential optical methods for assaying F508del modulation properties of compounds

[002411] The assay utilizes fluorescent voltage sensing dyes to measure changes in membrane potential using a fluorescent plate reader (e.g., FLIPR ΠΙ, Molecular Devices, Inc.) as a readout for increase in functional F508del in NIH 3T3 cells. The driving force for the response is the creation of a chloride ion gradient in conjunction with channel activation by a single liquid addition step after the cells have previously been treated with compounds and subsequently loaded with a voltage sensing dye.

Identification of Potentiator Compounds

[002412] To identify potentiators of F508del, a double-addition HTS assay format was developed. This HTS assay utilizes fluorescent voltage sensing dyes to measure changes in membrane potential on the FLIPR III as a measurement for increase in gating (conductance) of F508del in temperature-corrected F508del NIH 3T3 cells. The driving force for the response is a CI^' ion gradient in conjunction with channel activation with forskolin in a single liquid addition step using a fluorescent plate reader such as FLIPR HI after the cells have previously been treated with potentiator compounds (or DMSO vehicle control) and subsequently loaded with a redistribution dye. Solutions

[002413] Bath Solution #1: (in mM) NaCl 160, KC14.5, CaCl₂ 2, MgCl₂ 1, HEPES 10, pH 7.4 with NaOH.

[002414] Chloride-free bath solution: Chloride salts in Bath Solution #1 (above) are substituted with gluconate salts.

Cell Culture

[002415] NIH3T3 mouse fibroblasts stably expressing F508del are used for optical measurements of membrane potential. The cells are maintained at 37 °C in 5% C(¾ and 90 % humidity in Dulbecco's modified Eagle's medium supplemented with 2 mM glutamine, 10 % fetal bovine serum, 1 X NEAA, β-ΜΕ, 1 X pen/strep, and 25 mM HEPES in 175 cm² culture flasks. For all optical assays, the cells were seeded at ~20,000/well in 384-well matrigel-coated plates and cultured for 2 hrs at 37 °C before culturing at 27 °C for 24 hrs. for the potentiator assay. For the correction assays, the cells are cultured at 27 °C or 37 °C with and without compounds for 16 - 24 hours.

[002416] Electrophysiological Assays for assaying F508del modulation properties of compounds.

Ussine Chamber Assay

[002417] Ussing chamber experiments were performed on polarized airway epithelial cells expressing F508del to further characterize the F508del augmenters or inducers identified in the optical assays. Non-CF and CF airway epithelia were isolated from bronchial tissue, cultured as previously described (Galietta, L.J.V., Lantero, S., Gazzolo, A., Sacco, O., Romano, L., Rossi, G.A., & Zegarra-Moran, O. ( 1998) In Vitro Cell. Dev. Biol. 34, 478-481), and plated onto Costar® Snapwell™ filters that were precoated with NIH3T3-conditioned media. After four days the apical media was removed and the cells were grown at an air liquid interface for > 14 days prior to use. This resulted in a monolayer of fully differentiated columnar cells that were ciliated, features that are characteristic of airway epithelia. Non-CF HBE were isolated from non-smokers that did not have any known lung disease. CF-HBE were isolated from patients homozygous for F508del. [002418] HBE grown on Costar® Snapwell™ cell culture inserts were mounted in an Using chamber (Physiologic Instruments, Inc., San Diego, CA), and the transepithelial resistance and short-circuit current in the presence of a basolateral to apical CI^' gradient (Isc) were measured using a voltage-clamp system (Department of Bioengineering, University of Iowa, LA). Briefly, HBE were examined under voltage-clamp recording conditions (V^_d = 0 mV) at 37 °C. The basolateral solution contained (in mM) 145 NaCl, 0.83 K2HPO4, 3.3 KH₂P0₄, 1.2 MgCI₂, 1.2 CaCl₂, 10 Glucose, 10 HEPES (pH adjusted to 7.35 with NaOH) and the apical solution contained (in mM) 145 NaGluconate, 1.2 MgCl₂, 1.2 CaCl₂, 10 glucose, 10 HEPES (pH adjusted to 7.35 with NaOH).

Identification of Potentiator Compounds

[002419] Typical protocol utilized a basolateral to apical membrane CI^' concentration gradient. To set up this gradient, normal ringers was used on the basolateral membrane, whereas apical NaCl was replaced by equimolar sodium gluconate (titrated to pH 7.4 with NaOH) to give a large CI^' concentration gradient across the epithelium. Forskolin ( 10 μΜ) and all test compounds were added to the apical side of the cell culture inserts. The efficacy of the putative F508del potentiators was compared to that of the known potentiator, genistein.

Patch-clamp Recordings

[002420] Total CI^" current in F508del-NIH3T3 cells was monitored using the perforated-patch recording configuration as previously described (Rae, J., Cooper, K., Gates, P., & Watsky, M. (1991) J. Neurosci. Methods 37, 15-26). Voltage-clamp recordings were performed at 22 °C using an Axopatch 200B patch-clamp amplifier (Axon Instruments Inc., Foster City, CA). The pipette solution contained (in mM) 150 /V-methyl-D-glucamine (NMDG)-CI, 2 MgCl₂, 2 CaCl₂, 10 EGTA, 10 HEPES, and 240 amphotericin-B (pH adjusted to 7.35 with HC1). The extracellular medium contained (in mM) 150 NMDG-C1, 2 MgCl₂, 2 CaCl₂, 10 HEPES (pH adjusted to 7.35 with HC1). Pulse generation, data acquisition, and analysis were performed using a PC equipped with a Digidata 1320 A D interface in conjunction with Clampex 8 (Axon Instruments Inc.). To activate F508del, 10 μΜ forskolin and 20 μΜ genistein were added to the bath and the current-voltage relation was monitored every 30 sec.

Identification of Potentiator Compounds [002421] The ability of F508del potentiators to increase the macroscopic F508del CI^' current (lFS08dd) in NIH3T3 cells stably expressing F508del was also investigated using perforated-patch- recording techniques. The potentiators identified from the optical assays evoked a dose- dependent increase in IA^OS with similar potency and efficacy observed in the optical assays. In all cells examined, the reversal potential before and during potentiator application was around - 30 mV, which is the calculated Eci (-28 mV).

Cell Culture

[002422] NIH3T3 mouse fibroblasts stably expressing F508del are used for whole-cell recordings. The cells are maintained at 37 °C in 5% CO? and 90 % humidity in Dulbecco's modified Eagle's medium supplemented with 2 iuM glutamine, 10 % fetal bovine serum, 1 X NEAA, β-ΜΕ, 1 X pen strep, and 25 mM HEPES in 175 cm² culture flasks. For whole-cell recordings, 2,500 - 5,000 cells were seeded on poly-L-ly&ine-coated glass coverslips and cultured for 24 - 48 hrs at 27 °C before use to test the activity of potentiators; and incubated with or without the correction compound at 37 °C for measuring the activity of correctors.

Single-channel recordings

[002423] Gating activity of wt-CFTR and temperature-corrected F508del expressed in NIH3T3 cells was observed using excised inside-out membrane patch recordings as previously described (Dalemans, W„ Barbry, P., Champigny, G., Jallat, S., Dott, K., Dreyer, D., Crystal, R.G., Pavirani, A., Lecocq, J-P., Lazdunski, M. (1 91) Nature 354, 526 - 528) using an Axopatch 200B patch-clamp amplifier (Axon Instruments Inc.). The pipette contained (in mM): 1 0 NMDG, 150 aspartic acid, 5 CaCl₂, 2 MgCl₂, and 10 HEPES (pH adjusted to 7.35 with Tris base). The bath contained (in mM): 150 NMDG-C1, 2 MgCl₂, 5 EGTA, 10 TES, and 14 Tris base (pH adjusted to 7.35 with HC1). After excision, both wt- and F508del were activated by adding 1 mM Mg-ATP, 75 nM of the catalytic subunit of cAMP-dependent protein kinase (PKA; Promega Corp. Madison, WI), and 10 mM NaF to inhibit protein phosphatases, which prevented current rundown. The pipette potential was maintained at 80 mV. Channel activity was analyzed from membrane patches containing < 2 active channels. The maximum number of simultaneous openings determined the number of active channels during the course of an experiment. To determine the single-channel current amplitude, the data recorded from 120 sec of F508del activity was filtered "off-line" at 100 Hz and then used to construct all-point amplitude histograms that were fitted with multigaussian functions using Bio-Patch Analysis software (Bio-Logic Comp. France). The total microscopic current and open probability (P₀) were determined from 120 sec of channel activity. The P₀ was determined using the Bio-Patch software or from the relationship P₀ = I/i(N), where I = mean current, i = single-channel current amplitude, and N = number of active channels in patch.

Cell Culture

[002424] ΝΪΗ3Τ3 mouse fibroblasts stably expressing F508del are used for excised-membrane patch-clamp recordings. The cells are maintained at 37 °C in 5% C(¾ and 90 % humidity in Dulbecco's modified Eagle's medium supplemented with 2 mM glutamine, 10 % fetal bovine serum, 1 X NEAA, β-ΜΕ, 1 X pen strep, and 25 mM HEPES in 175 cm² culture flasks. For single channel recordings, 2,500 - 5,000 cells were seeded on poly-L-lysine-coated glass coverslips and cultured for 24 - 48 hrs at 27 °C before use.

[002426] Assays for Detecting and Measuring F508del Correction Properties of

Compounds

[002427] Membrane potential optical methods for assaying F508del modulation properties of compounds.

[002428] The optical membrane potential assay utilized voltage-sensitive FRET sensors described by Gonzalez and Tsien {See Gonzalez, J. E. and R. Y. Tsien (1995) "Voltage sensing by fluorescence resonance energy transfer in single cells" Biophvs J 69(4): 1272-80, and Gonzalez, J. E. and R. Y. Tsien (1997) "Improved indicators of cell membrane potential that use fluorescence resonance energy transfer" Chem Biol 4(4): 269-77) in combination with instrumentation for measuring fluorescence changes such as the Voltage/Ion Probe Reader (VIPR) (See. Gonzalez, J. E., K. Oades, et al. (1999) "Cell-based assays and instrumentation for screening ion-channel targets" Drug Discov Today 4(9): 431-439).

[002429] These voltage sensitive assays are based on the change in fluorescence resonant energy transfer (FRET) between the membrane-soluble, voltage-sensitive dye, DiSBAC₂(3), and a fluorescent phospholipid, CC2-DMPE, which is attached to the outer leaflet of the plasma membrane and acts as a FRET donor. Changes in membrane potential (V_m) cause the negatively charged DiSBAC₂(3) to redistribute across the plasma membrane and the amount of energy transfer from CC2-DMPE changes accordingly. The changes in fluorescence emission were monitored using VIPR™ II, which is an integrated liquid handler and fluorescent detector designed to conduct cell-based screens in 96- or 384-well microliter plates.

Identification of Correction Compounds

[002430] To identify small molecules that correct the trafficking defect associated with F508del; a single-addition HTS assay format was developed. The cells were incubated in serum-free medium for 16 hrs at 37 °C in the presence or absence (negative control) of test compound. As a positive control, cells plated in 384-well plates were incubated for 16 hrs at 27 °C to

"temperature-correct" F508del. The cells were subsequently rinsed 3X with Krebs Ringers solution and loaded with the voltage-sensitive dyes. To activate F508del, 10 μΜ forskolin and the CFTR potentiator, genistein (20 μΜ), were added along with CP-free medium to each well. The addition of Cl -free medium promoted CI^' efflux in response to F508del activation and the resulting membrane depolarization was optically monitored using the FRET-based voltage- sensor dyes.

Identification of Potentiator Compounds

[002431] To identify potentiators of F508del, a double-addition HTS assay format was developed. During the first addition, a Cl -free medium with or without lest compound was added to each well. After 22 sec, a second addition of Cl -free medium containing 2 - 10 μΜ forskolin was added to activate F508del. The extracellular CI^' concentration following both additions was 28 mM, which promoted CI^' efflux in response to F508del activation and the resulting membrane depolarization was optically monitored using the FRET-based voltage- sensor dyes.

[002436] NIH3T3 mouse fibroblasts stably expressing F508del are used for optical

measurements of membrane potential. The cells are maintained at 37 °C in 5% CO2 and 90 % humidity in Dulbecco's modified Eagle's medium supplemented with 2 mM glutamine, 10 % fetal bovine serum, 1 X NEAA, β-ΜΕ, 1 X pen/strep, and 25 mM HEPES in 175 cm² culture flasks. For all optical assays, the cells were seeded at 30,000/well in 384-well matrigel-coated plates and cultured for 2 hrs at 37 °C before culturing at 27 °C for 24 hrs for the potentiator assay. For the correction assays, the cells are cultured at 27 °C or 37 °C with and without compounds for 16 - 24 hours.

[002437] Electrophysiological Assays for assaying F508del modulation properties of compounds

Ussing Chamber Assay

[002438] Using chamber experiments were performed on polarized epithelial cells expressing F508del to further characterize the F508del augmenters or inducers identified in the optical assays. FRT ^F50Mel epithelial cells grown on Costar Snapwell cell culture inserts were mounted in an Ussing chamber (Physiologic Instruments, Inc., San Diego, CA), and the monolayers were continuously short-circuited using a Voltage-clamp System (Department of Bioengineering, University of Iowa, IA, and, Physiologic Instruments, Inc., San Diego, CA). Transepithelial resistance was measured by applying a 2-mV pulse. Under these conditions, the FRT epithelia demonstrated resistances of 4 ΚΩ/ cm² or more. The solutions were maintained at 27 *C and bubbled with air. The electrode offset potential and fluid resistance were corrected using a cell- free insert. Under these conditions, the current reflects the flow of CI^' through F508del expressed in the apical membrane. The e was digitally acquired using an MP100A-CE interface and AcqKnowledge software (v3.2.6; BIOPAC Systems, Santa Barbara, CA).

Identification of Correction Compounds [002439] Typical protocol utilized a basolateral to apical membrane CI^' concentration gradient. To set up this gradient, normal ringer was used on the basolateral membrane, whereas apical NaCl was replaced by equimolar sodium gluconate (titrated to pH 7.4 with NaOH) to give a large CI^' concentration gradient across the epithelium. All experiments were performed with intact monolayers. To fully activate F508del, forskolin (10 μΜ) and the PDE inhibitor, EBMX (100 μΜ), were applied followed by the addition of the CFTR potentiator, genistein (50 μΜ).

[002440] As observed in other cell types, incubation at low temperatures of FRT cells stably expressing F508del increases the functional density of CFTR in the plasma membrane. To determine the activity of correction compounds, the cells were incubated with 10 μΜ of the test compound for 24 hours at 37°C and were subsequently washed 3X prior to recording. The cAMP- and genistein-mediated Isc in compound-treated cells was normalized to the 27°C and 37°C controls and expressed as percentage activity. Preincubation of the cells with the correction compound significantly increased the cAMP- and genistein-mediated Isc compared to the 37^aC controls.

Identification of Potentiator Compounds

[002441] Typical protocol utilized a basolateral to apical membrane CI^' concentration gradient. To set up this gradient, normal ringers was used on the basolateral membrane and was permeabilized with nystatin (360 μξ/ml), whereas apical NaCl was replaced by equimolar sodium gluconate (titrated to pH 7.4 with NaOH) to give a large CI concentration gradient across the epithelium. All experiments were performed 30 min after nystatin permeabilization. Forskolin (10 μΜ) and all test compounds were added to both sides of the cell culture inserts. The efficacy of the putative F508del potentiators was compared to that of the known potentiator, genistein.

Solutions

[002442] Basolateral solution (in mM): NaCl (135), CaCl₂ (1.2), MgCl₂ (1.2),

K2HPO4 (2.4), HPO4 (0.6), JV-2- hydroxyethylpiperazine-N^,-2-ethanesulfonic acid (HEPES) (10), and dextrose (10). The solution was titrated to pH 7.4 with NaOH. 109 O

[002443] Apical solution (in mM): Same as basolateral solution with NaCl replaced with Na Gluconate (135).

Cell Culture

[002444] Fisher rat epithelial (FRT) cells expressing F508del (FRT ^ΚΙ)Μβ1) were used for Ussing chamber experiments for the putative F508del augmenters or inducers identified from our optical assays. The cells were cultured on Costar Snapwell cell culture inserts and cultured for five days at 37 °C and 5% CO2 in Coon's modified Ham's F-12 medium supplemented with 5% fetal calf serum, 100 U/ml penicillin, and 100 μg/ml streptomycin. Prior to use for characterizing the potentiator activity of compounds, the cells were incubated at 27 °C for 16 - 48 hrs to correct for the F508del. To determine the activity of corrections compounds, the cells were incubated at 27 °C or 37 ^aC with and without the compounds for 24 hours.

Whole-cell recordings

[002445] The macroscopic F508del current (l_fsos_dei) in temperature- and test compound- corrected NIH3T3 cells stably expressing F508del were monitored using the perforated-patch, whole-cell recording. Briefly, voltage-clamp recordings of iFsowei were performed at room temperature using an Axopatch 2006 patch-clamp amplifier (Axon Instruments Inc., Foster City, CA). All recordings were acquired at a sampling frequency of 10 kHz and low-pass filtered at 1 kHz. Pipettes had a resistance of 5 - 6 ΜΩ when filled with the intracellular solution. Under these recording conditions, the calculated reversal potential for CI^' (¾) at room temperature was -28 mV. All recordings had a seal resistance > 20 G 1 and a series resistance < 15 ΜΩ. Pulse generation, data acquisition, and analysis were performed using a PC equipped with a Digidata 1320 A/D interface in conjunction with Clampex 8 (Axon Instruments Inc.). The bath contained < 250 μΐ of saline and was continuously perifused at a rate of 2 ml/min using a gravity-driven perfusion system.

Identification of Correction Compounds

[002446] To determine the activity of correction compounds for increasing the density of functional F508del in the plasma membrane, we used the above-described perforated-patch- recording techniques to measure the current density following 24-hr treatment with the correction compounds. To fully activate F508del, 10 μΜ forskolin and 20 μΜ genistein were added to the cells. Under our recording conditions, the current density following 24-hr incubation at 27°C was higher than that observed following 24-hr incubation at 37 °C. These results are consistent with the known effects of low-temperature incubation on the density of F508del in the plasma membrane. To determine the effects of correction compounds on CFTR current density, the cells were incubated with 10 μΜ of the test compound for 24 hours at 37°C and the current density was compared to the 27*C and 37°C controls ( activity). Prior to recording, the cells were washed 3X with extracellular recording medium to remove any remaining test compound. Preincubation with 10 μΜ of correction compounds significantly increased the cAMP- and genistein-dependent current compared to the 37°C controls.

Identification of Potentiator Compounds

[002447] The ability of F508del potentiators to increase the macroscopic F508del CI^' current (lF508dei) in NIH3T3 cells stably expressing F50Sdel was also investigated using perforated-patch- recording techniques. The potentiators identified from the optical assays evoked a dose- dependent increase in ouei with similar potency and efficacy observed in the optical assays. In all cells examined, the reversal potential before and during potentiator application was around - 30 mV, which is the calculated Eci (-28 mV).

Cell Culture

[002450] NIH3T3 mouse fibroblasts stably expressing F508del are used for whole-cell recordings. The cells are maintained at 37 °C in 5% C0₂ and 90 % humidity in Dulbecco's modified Eagle's medium supplemented with 2 mM glutamine, 10 % fetal bovine serum, 1 X NEAA, β-ΜΕ, 1 X pen/strep, and 25 mM HEPES in 175 cm² culture flasks. For whole-cell recordings, 2,500 - 5,000 cells were seeded on poly-L-lysine-coated glass coverslips and cultured P 09 O for 24 - 48 hrs at 27 °C before use to test the activity of potentiators; and incubated with or without the correction compound at 37 *C for measuring the activity of correctors.

Single-channel recordings

[002451] The single-channel activities of temperature-corrected F508del stably expressed in NIH3T3 cells and activities of potentiator compounds were observed using excised inside-out membrane patch. Briefly, voltage-clamp recordings of single-channel activity were performed at room temperature with an Axopatch 200B patch-clamp amplifier (Axon Instruments Inc.). All recordings were acquired at a sampling frequency of 10 kHz and low-pass filtered at 400 Hz. Patch pipettes were fabricated from Corning Kovar Sealing #7052 glass (World Precision Instruments, Inc., Sarasota, FL) and had a resistance of 5 - 8 ΜΩ when filled with the extracellular solution. The F508del was activated after excision, by adding 1 mM Mg-ATP, and 75 nM of the cAMP-dependent protein kinase, catalytic subunit (PKA; Promega Corp. Madison, WI). After channel activity stabilized, the patch was peri fused using a gravity-driven

microperfusion system. The inflow was placed adjacent to the patch, resulting in complete solution exchange within 1 - 2 sec. To maintain F508del activity during the rapid perifusion, the nonspecific phosphatase inhibitor F (10 mM NaF) was added to the bath solution. Under these recording conditions, channel activity remained constant throughout the duration of the patch recording (up to 60 min). Currents produced by positive charge moving from the intra- to extracellular solutions (anions moving in the opposite direction) are shown as positive currents. The pipette potential (V_p) was maintained at 80 mV.

[002452] Channel activity was analyzed from membrane patches containing < 2 active channels. The maximum number of simultaneous openings determined the number of active channels during the course of an experiment. To determine the single-channel current amplitude, the data recorded from 120 sec of F508del activity was filtered "off-line" at 100 Hz and then used to construct all-point amplitude histograms that were fitted with multigaussian functions using Bio- Patch Analysis software (Bio-Logic Comp. France). The total microscopic current and open probability (P₀) were determined from 120 sec of channel activity. The P₀ was determined using the Bio-Patch software or from the relationship P₀ = I i(N), where I = mean current, i = single- channel current amplitude, and N = number of active channels in patch.

For single channel recordings, 2,500 - 5,000 cells were seeded on poly-L-Iysine-coated glass coverslips and cultured for 24 - 48 hrs at 27 ^eC before use.
