BACKGROUND
[0002] Cystic fibrosis (CF) is a lethal, recessive, genetic disease
affecting approximately 1 in 2500 live births among Caucasians.
(Cohen-Cymberknoh M, Shoseyov D, Kerem E. Managing cystic fibrosis:
strategies that increase life expectancy and improve quality of
life. Am J Respir Crit Care Med (2011); 183: 1463-1471; Boat T F,
Welsh M J and Beaudet A L. Cystic fibrosis. (1989) IN "The
Metabolic Basis of Inherited Disease" (C L Scriver, A L Beaudet, W
S Sly and D Valee, eds.), 6.sup.th Ed., pp. 2649-2680. McGraw-Hill,
New York. Approximately 1 in 25 persons are carriers of the genetic
defect associated with disease. The major symptoms of cystic
fibrosis include chronic pulmonary disease, pancreatic exocrine
insufficiency, infertility in males, and elevated sweat electrolyte
levels. The symptoms are consistent with cystic fibrosis being an
exocrine disorder. (Hantash F: U.S. Patent Application No.
20060057593. Method for detecting cystic fibrosis).
[0003] The CF gene codes for a cAMP/PKA-dependent, ATP-requiring,
membrane-bound chloride ion channel known as CFTR (cystic fibrosis
transmembrane conductance regulator), and is, generally localized
to the apical membranes of many secreting. There are currently over
1700 known mutations affecting CFTR, many of which give rise to a
disease phenotype. Around 75% of CF alleles contain the .DELTA.F508
mutation in which a triplet codon has been lost, leading to a
missing phenylalanine at position 508 in the protein. This altered
protein fails to be trafficked to the correct location in the cell
and is generally destroyed by the proteasome. The small amount that
does reach the correct location functions poorly. (Cutbert A W. New
horizons in the treatment of cystic fibrosis. British J Pharm,
(2011), 163: 173-183).
[0004] Mutations in the CFTR gene result in absence or dysfunction
of the protein that regulates ion transport across the apical
membrane at the surface of certain epithelia. Although CFTR
functions mainly as a chloride channel, it has many other roles,
including inhibition of sodium transport through the epithelial
sodium channel, regulation of the outwardly rectifying chloride
channel, ATP channels, intracellular vesicle transport, and
inhibition of endogenous calcium-activated chloride channels. CFTR
is also involved in bicarbonate-chloride exchange. A deficiency in
bicarbonate secretion leads to poor solubility and aggregation of
luminal mucins. Obstruction of intrapancreatic ducts with thickened
secretions causes autolysis of pancreatic tissue with replacement
of the body of the pancreas with fat, leading to pancreatic
insufficiency with subsequent malnutrition. In the lungs, CFTR
dysfunction leads to airway surface liquid (ASL) depletion and
thickened and viscous mucus that adheres to airway surfaces. The
result is decreased mucociliary clearance (MCC) and impaired host
defenses. Dehydrated, thickened secretions lead to endobronchial
infection with a limited spectrum of distinctive bacteria, mainly
Staphylococcus aureus and Pseudomonas aeruginosa, Deficiency in
bicarbonate secretion due to loss of CFTR function also results in
a lower pH at the airway surface which impairs anti-bacterial
killing activity and increases susceptibility to infection. An
exaggerated inflammatory response in response to chronic lung
infections leads to the development of bronchiectasis and
progressive obstructive airways disease. Pulmonary insufficiency is
responsible for most CF-related deaths. (Cohen-Cymberknoh M,
Shoseyov D, Kerem E. Managing cystic fibrosis: strategies that
increase life expectancy and improve quality of life. Am J Respir
Crit Care Med (2011); 183: 1463-1471).
[0005] The prognosis for the treatment of CF has improved over the
last 40 years. This was achieved by improving pancreatic enzyme
supplements, drugs designed to treat pulmonary infection, reduce
inflammation and enhance mucociliary clearance. Currently the
therapeutic challenges are to correct the biochemical defect of CF
and to identify effective treatments for chronic respiratory
infection. (Frerichs C, Smyth A. Treatment strategies for cystic
fibrosis: what's in the pipeline? Pharmacotherapty (2009), 10:
1191-1202).

commonly used in the art such as, for example, water or other
solvents, solubilizing agents and emulsifiers such as ethyl
alcohol, isopropyl alcohol, ethyl carbonate, EtOAc, benzyl alcohol,
benzyl benzoate, propylene glycol, 1, 3-butylene glycol,
dimethylformamide, oils (in particular, cottonseed, groundnut,
corn, germ, olive, castor, and sesame oils), glycerol,
tetrahydrofurfuryl alcohol, polyethylene glycols and fatty acid
esters of sorbitan, and mixtures thereof. Besides inert diluents,
the oral compositions can also include adjuvants such as wetting
agents, emulsifying and suspending agents, sweetening, flavoring,
and perfuming agents.
[0050] Injectable preparations, for example, sterile injectable
aqueous or oleaginous suspensions, may be formulated according to
the known art using suitable dispersing or wetting agents and
suspending agents. The sterile injectable preparation may also be a
sterile injectable suspension or emulsion, such as INTRALIPID.RTM.,
LIPOSYN.RTM. or OMEGAVEN.RTM., or solution, in a nontoxic
parenterally acceptable diluent or solvent, for example, as a
solution in 1, 3-butanediol. INTRALIPID.RTM. is an intravenous fat
emulsion containing 10-30% soybean oil, 1-10% egg yolk
phospholipids, 1-10% glycerin and water. LIPOSYN.RTM. is also an
intravenous fat emulsion containing 2-15% safflower oil, 2-15%
soybean oil, 0.5-5% egg phosphatides 1-10% glycerin and water.
OMEGAVEN.RTM. is an emulsion for infusion containing about 5-25%
fish oil, 0.5-10% egg phosphatides, 1-10% glycerin and water. Among
the acceptable vehicles and solvents that may be employed are
water, Ringer's solution, USP and isotonic sodium chloride
solution. In addition, sterile, fixed oils are conventionally
employed as a solvent or suspending medium. For this purpose any
bland fixed oil can be employed including synthetic mono- or
diglycerides. In addition, fatty acids such as oleic acid are used
in the preparation of injectables.
[0051] The injectable formulations can be sterilized, for example,
by filtration through a bacterial-retaining filter, or by
incorporating sterilizing agents in the form of sterile solid
compositions which can be dissolved or dispersed in sterile water
or other sterile injectable medium prior to use.
[0052] Compositions for rectal or vaginal administration are
preferably suppositories which can be prepared by mixing the
compounds of this invention with suitable non-irritating excipients
or carriers such as cocoa butter, polyethylene glycol or a
suppository wax which are solid at ambient temperature but liquid
at body temperature and therefore melt in the rectum or vaginal
cavity and release the active compound.
[0053] Solid dosage forms for oral administration include capsules,
tablets, pills, powders, and granules. In such solid dosage forms,
the active compound is mixed with at least one inert,
pharmaceutically acceptable excipient or carrier such as sodium
citrate or dicalcium phosphate and/or: a) fillers or extenders such
as starches, lactose, sucrose, glucose, mannitol, and silicic acid;
b) binders such as, for example, carboxymethylcellulose, alginates,
gelatin, polyvinylpyrrolidinone, sucrose, and acacia; c) humectants
such as glycerol; d) disintegrating agents such as agar-agar,
calcium carbonate, potato or tapioca starch, alginic acid, certain
silicates, and sodium carbonate; e) solution retarding agents such
as paraffin; f) absorption accelerators such as quaternary ammonium
compounds; g) wetting agents such as, for example, cetyl alcohol
and glycerol monostearate; h) absorbents such as kaolin and
bentonite clay; and i) lubricants such as talc, calcium stearate,
magnesium stearate, solid polyethylene glycols, sodium lauryl
sulfate, and mixtures thereof. In the case of capsules, tablets and
pills, the dosage form may also comprise buffering agents.
[0054] Solid compositions of a similar type may also be employed as
fillers in soft and hard-filled gelatin capsules using such
excipients as lactose or milk sugar as well as high molecular
weight polyethylene glycols and the like.
[0055] The solid dosage forms of tablets, dragees, capsules, pills,
and granules can be prepared with coatings and shells such as
enteric coatings and other coatings well known in the
pharmaceutical formulating art. They may optionally contain
opacifying agents and can also be of a composition that they
release the active ingredient(s) only, or preferentially, in a
certain part of the intestinal tract, optionally, in a delayed
manner. Examples of embedding compositions that can be used include
polymeric substances and waxes.
[0056] Dosage forms for topical or transdermal administration of a
compound of this invention include ointments, pastes, creams,
lotions, gels, powders, solutions, sprays, inhalants or patches.
The active component is admixed under sterile conditions with a
pharmaceutically acceptable carrier and any needed preservatives or
buffers as may be required. Ophthalmic formulation, ear drops, eye
ointments, powders and solutions are also contemplated as being
within the scope of this invention.
[0057] The ointments, pastes, creams and gels may contain, in
addition to an active compound of this invention, excipients such
as animal and vegetable fats, oils, waxes, paraffins, starch,
tragacanth, cellulose derivatives, polyethylene glycols, silicones,
bentonites, silicic acid, talc and zinc oxide, or mixtures
thereof.
[0058] Powders and sprays can contain, in addition to the compounds
of this invention, excipients such as lactose, talc, silicic acid,
aluminum hydroxide, calcium silicates and polyamide powder, or
mixtures of these substances. Sprays can additionally contain
customary propellants such as chlorofluorohydrocarbons.
[0059] Transdermal patches have the added advantage of providing
controlled delivery of a compound to the body. Such dosage forms
can be made by dissolving or dispensing the compound in the proper
medium. Absorption enhancers can also be used to increase the flux
of the compound across the skin. The rate can be controlled by
either providing a rate controlling membrane or by dispersing the
compound in a polymer matrix or gel.
[0060] For pulmonary delivery, a therapeutic composition of the
invention is formulated and administered to the patient in solid or
liquid particulate form by direct administration e.g., inhalation
into the respiratory system. Solid or liquid particulate forms of
the active compound prepared for practicing the present invention
include particles of respirable size: that is, particles of a size
sufficiently small to pass through the mouth and larynx upon
inhalation and into the bronchi and alveoli of the lungs. Delivery
of aerosolized therapeutics is known in the art (see, for example
U.S. Pat. No. 5,767,068 to VanDevanter et al., U.S. Pat. No.
5,508,269 to Smith et al., and WO 98/43650 by Montgomery).

"aryloxy", "alkylthio", "aryl", "heteroaryl", "heterocyclic",
"alkyl" "alkenyl", "alkynyl", "aliphatic", or "cycloalkyl", those

[0091] "Treatment" or "treating" refers to an approach for
obtaining beneficial or desired clinical results in a patient. For
purposes of this invention, beneficial or desired clinical results
include, but are not limited to, one or more of the following:
alleviation of symptoms, diminishment of extent of a disease,

preventing spread (i.e., metastasis) of disease, preventing
occurrence or recurrence of disease, delay or slowing of disease
progression, amelioration of the disease state, and remission
(whether partial or total).

Assays for Detecting and Measuring the Effect of Compounds on
F508del-CFTR Channels CFTR-YFP High Throughput Assay-CFTR Corrector
Protocol:
[0307] This protocol is designed to selectively screen small
molecule compounds for F508del CFTR corrector activities in the HTS
YFP (yellow fluorescent protein) flux assay. In this protocol, the
cells are incubated with testing compounds for 24 hours, washed
with PBS, stimulated with forskolin and a standard potentiator, and
fluorescence in each plate well is measured kinetically read on a
384-well HTS plate reader, such as the Hamamatsu FDSS-6000.
[0308] YFP fluorescence intensity values are acquired at high speed
before and after iodide buffer is injected to the assay cells.
Iodide enters the cells via active CFTR channels in the plasma
membrane, and quenches the YFP fluorescence. The rate of
fluorescence quenching is proportionate to the total CFTR activity
in the cell membrane. F508del CFTR correctors increase the number
of CFTR molecules in the testing cell plasma membrane, and thereby
accelerate YFP quenching.
[0309] This method was initially developed for bench top plate
readers (Galietta et al., 2001), and was adapted to the HTS format
(Sui et al. Assay Drug Dev. Technol. 2010).
[0310] Fisher Rat Thyroid (FRT) cells stably expressing both human
F508del CFTR and a halide-sensitive yellow fluorescent protein
(YFP-H148Q/I152L 25,22) (Galietta et al. Am. J. Physiol Cell
Physiol 281(5), C1734, 2001) were cultured on plastic surface in
Coon's modified Ham's F12 medium supplemented with FBS 10%,
L-glutamine 2 mM, penicillin 100 U/ml, and streptomycin 100 g/ml.
G418 (0.75-1.0 mg/ml) and zeocin (3.2 ug/ml) were used for
selection of FRT cells expressing F508del CFTR and YFP. For primary
screening, FRT cells were plated into 384-well black wall,
transparent bottom microtiter plates (Costar; Corning Inc.) at a
cell density of 20,000-40,000 per well. Test compound was applied
to the cells at varying concentrations ranging from 2 nM-40 .mu.M
in either a 2-fold or 3-fold dilution series. Cells were incubated
in a cell culture incubator at 37.degree. C. with 5% CO.sub.2 for
24-26 h. Assay plates were washed with DPBS media (Thermo, cat #
SH30028.02) to remove unbound cells and compound. Stimulation media
(25 .mu.L) containing 20 .mu.M Forskolin & 30 .mu.M P3
[6-(Ethyl-phenyl-sulfonyl)-4-oxo-1,4-dihydro-quinoline-3-carboxylic
acid 2-methoxy-benzylamide] in Hams F-12 coon's modified media was
added to the plate wells and incubated at room temperature for
60-120 min. 25 .mu.L of HEPES-PBS-I buffer (10 mM HEPES, 1 mM
MgCl.sub.2, 3 mM KCl, 1 mM CaCl.sub.2, 150 mM NaI) was then added
and fluorescence quench curves (Excitation 500 nm/Emission 540 nm;
exposure 136 ms) were immediately recorded on an FDSS-6000 plate
reader (Hamamatsu). Quench rates were derived from least squares
fitting of the data as described by Sui et al (2010).
CFTR-YFP High Throughput Assay-CFTR Potentiator Protocol:
[0311] This protocol is designed to selectively screen small
molecule compounds for F508del CFTR potentiator activities in the
HTS YFP flux assay. Such compounds act acutely to stimulate CFTR
already expressed on the membrane surface. In this protocol, the
cells are incubated at 27.degree. C. for 24 hours to homogeneously
boost F508del CFTR expression in the cell membrane (low temperature
correction), washed with PBS, treated with test compound, and CFTR
activity is stimulated with forskolin for 1-2 hr. Measurement of
ion flux is initiated by addition of iodide-containing buffer, and
YFP quenching is kinetically recorded using a 384-well HTS plate
reader, such as the Hamamatsu FDSS-6000.
[0312] YFP fluorescence intensity values are acquired at high speed
over a 1 min time course before and after iodide buffer is injected
to the assay cells. Iodide enters the cells via active CFTR
channels in the plasma membrane, and quenches the YFP fluorescence.
The rate of fluorescence quenching is proportionate to total CFTR
activity in the cell membrane. F508del-CFTR potentiators increase
CFTR open probability or CFTR-mediated ion conductivity, and this
enhanced CFTR mediated iodide flux in the test cell plasma membrane
accelerates YFP quenching.
[0313] This method was initially developed for bench top plate
readers (Galietta et al., 2001), and was adapted to the HTS format
(Sui et al. Assay Drug Dev. Technol. 2010).
[0314] Fisher Rat Thyroid (FRT) cells stably expressing both human
F508del CFTR and a halide-sensitive yellow fluorescent protein
(YFP-H148Q/I152L 25,22) (Galietta et al., Am. J. Physiol Cell
Physiol 281(5), C1734, 2001) were cultured on plastic surface in
Coon's modified Ham's F12 medium supplemented with FBS 10%,
L-glutamine 2 mM, penicillin 100 U/ml, and streptomycin 100
.mu.g/ml. G418 (0.75-1.0 mg/ml) and zeocin (3.2 ug/ml) were used
for selection of FRT cells expressing F508del CFTR and YFP. For

h. Assay plates were washed with DPBS media (Thermo, cat #
SH30028.02) to remove unbound cells. Test compound was applied to
the cells at varying concentrations ranging from 2 nM-40 .mu.M in
either a 2-fold or 3-fold dilution series in DPBS and stimulated
with 20 .mu.M Forskolin (final concentration) in Hams F-12 coon's
modified media. Plates were incubated at room temperature for
60-120 min. 25 .mu.L of HEPES-PBS-I buffer (10 mM HEPES, 1 mM
MgCl.sub.2, 3 mM KCl, 1 mM CaCl.sub.2, 150 mM NaI) was then added
and fluorescence quench curves (Excitation 500 nm/Emission 540 nm;

Cell Culture:
[0317] Primary CF airway epithelial cells were obtained from the
UNC Cystic Fibrosis Tissue Procurement and Cell Culture Core. The
cells are grown at 37.degree. C. in a Heracell 150i incubator using
growth media (BEGM, Fischer). Cells were then transferred to
differentiation media (ALI, UNC) for a minimum of 4 weeks on coated
Costar snapwells. Two days before the Ussing assay the mucus on the
apical surface of the cells was aspirated after incubating with 200
.mu.L of differentiation Media for at least thirty (30) minutes.
One day before the Ussing assay, test compounds were applied to the
basolateral surface of the cells at various test concentrations
(n=3 or n=4 replicates per test condition).
Ussing Assay
[0318] Ussing chambers and the associated voltage clamp were
obtained from Physiologic Instruments, (San Diego, Calif.). Ussing
assays were performed at the 37.degree. C. HEPES buffered
physiological saline (HB-PS) was used in apical and basolateral
chambers with glucose added to the basolateral solutions. Epithelia
were equilibrated for 15 minutes in the chambers while the bath
temperature and transepithelial voltage were stabilized and
adjusted before application of voltage clamp.
[0319] Compounds were added in the following order.
TABLE-US-00021 Step Chamber 3.0 uM Benzamil for 20 minutes apical
addition only 10 uM Forskolin for 20 minutes apical + basolateral
addition 10 uM Genestein for 20 minutes apical + basolateral
addition 10 uM CFTR-172 for 20 minutes apical + basolateral
addition 20 uM Bumetanide for 30 minutes basolateral addition
only
[0320] The short circuit current and transepithelial resistances
(typically >300 .OMEGA.-cm2) from each chamber was recorded
every 10 seconds on stored on a PC using Acquire and Analyze
(Physiologic Instruments).
Analysis
[0321] Efficacy of test compounds was compared using the average of
the forskolin response and the CFTR-172 inhibited current response
of the test compound divided by the average of the forskolin
response and the CFTR-172 inhibited current elicited by the
positive control. Normalized scores were tabulated for all
compounds and concentrations.
