The present disclosure relates to inhibitors of induced myeloid leukemia cell differentiation protein (MCL-1), compositions containing compounds described herein, and methods of treatment thereof.
Apoptosis, a type of programmed cell death, is critical for normal development and for preservation of cellular homeostasis. Dysregulation of apoptosis is recognized to play an important role in the development of various diseases. For example, blocks in apoptotic signaling are a common requirement for oncogenesis, tumor maintenance and chemoresistance (Hanahan, D. et al. Cell 2000, 100, 57). Apoptotic pathways can be divided into two categories, intrinsic and extrinsic, depending on the origin of the death signal. The intrinsic pathway, or mitochondrial apoptotic pathway, is initiated by intracellular signals that ultimately lead to mitochondrial outer membrane permeabilization (MOMP), caspase activation and cell death.
The intrinsic mitochondrial apoptotic pathway is highly regulated, and the dynamic binding interactions between the pro-apoptotic (e.g. BAX, BAK, BAD, BIM, NOXA) and anti-apoptotic (e.g. BCL-2, BCL-XL, MCL-1) BCL-2 family members control commitment to cell death (Youle, R. J. et al. Nat. Rev. Mol. Cell Biol. 2008, 9, 47). BAK and BAX are essential mediators that upon conformational activation cause MOMP, an irreversible event that subsequently leads to cytochrome c release, caspase activation and cell death. Anti-apoptotic BCL-2 family members such as BCL-2, BCL-XL and MCL-1 can bind and sequester their pro-apoptotic counterparts, thus preventing BAX/BAK activation and promoting cell survival.
BCL-2 plays a dominant role in the survival of several hematological malignancies where it is frequently overexpressed, whereas BCL-XL is a key survival protein in some hematological and solid tumors. The related anti-apoptotic protein MCL-1 is implicated in mediating malignant cell survival in a number of primary tumor types (Ashkenazi, A. et al. Nature Rev Drug Discovery 2017, 16, 273). MCL-1 gene amplifications are frequently found in human cancers, including breast cancer and non-small cell lung cancer (Beroukhim, R. et al. Nature 2010, 463, 899), and the MCL-1 protein has been shown to mediate survival in models of multiple myeloma (Derenn, S. et al. Blood 2002, 100, 194), acute myeloid leukemia (Glaser, S. et al. Genes Dev 2012, 26, 120) and MYC-driven lymphomas (Kelly, G. et al. Genes Dev 2014, 28, 58). Specific compounds that broadly inhibit gene transcription (e.g., CDK9 inhibitors) exert their cytotoxic effects on tumor cells, at least in part, by down-regulating MCL-1 (Kotschy, A. et al. Nature 2016, 538, 477); alvocidib (Kim, W. et al. Blood 2015, 126, 1343) and dinaciclib (Gregory, G. et al. Leukemia 2015, 29, 1437) are two examples that have demonstrated clinical proof-of-concept in patients with hematological malignancies. Literature data supports a role for MCL-1 as a resistance factor to anticancer therapies such gemcitabine, vincristine and taxol (Wertz, I. E. et al. Nature 2011, 471, 110). Accordingly, there is a need in the therapeutic arts for compounds which inhibit the activity of the MCL-1 protein.

A moiety is described as “substituted” when a non-hydrogen radical is in the place of hydrogen radical of any substitutable atom of the moiety. Thus, for example, a substituted heterocycle moiety is a heterocycle moiety in which at least one non-hydrogen radical is in the place of a hydrogen radical on the heterocycle. It should be recognized that if there are more than one substitution on a moiety, each non-hydrogen radical may be identical or different (unless otherwise stated).
If a moiety is described as being “optionally substituted,” the moiety may be either (1) not substituted or (2) substituted. If a moiety is described as being optionally substituted with up to a particular number of non-hydrogen radicals, that moiety may be either (1) not substituted; or (2) substituted by up to that particular number of non-hydrogen radicals or by up to the maximum number of substitutable positions on the moiety, whichever is less. Thus, for example, if a moiety is described as a heteroaryl optionally substituted with up to 3 non-hydrogen radicals, then any heteroaryl with less than 3 substitutable positions would be optionally substituted by up to only as many non-hydrogen radicals as the heteroaryl has substitutable positions. To illustrate, tetrazolyl (which has only one substitutable position) would be optionally substituted with up to one non-hydrogen radical. To illustrate further, if an amino nitrogen is described as being optionally substituted with up to 2 non-hydrogen radicals, then a primary amino nitrogen will be optionally substituted with up to 2 non-hydrogen radicals, whereas a secondary amino nitrogen will be optionally substituted with up to only 1 non-hydrogen radical.

In certain embodiments, “treat,” “treating,” and “treatment” refer to ameliorating at least one physical parameter, which may not be discernible by the subject. In yet another embodiment, “treat”, “treating”, and “treatment” refer to modulating the disease or disorder, either physically (for example, stabilization of a discernible symptom), physiologically (for example, stabilization of a physical parameter), or both. In a further embodiment, “treat”, “treating”, and “treatment” refer to slowing the progression of the disease or disorder.
The terms “prevent”, “preventing”, and “prevention” refer to a method of preventing the onset of a disease and/or its attendant symptoms or barring a subject from acquiring a disease. As used herein, “prevent”, “preventing” and “prevention” also include delaying the onset of a disease and/or its attendant symptoms and reducing a subject's risk of acquiring or developing a disease or disorder.
The phrase “therapeutically effective amount” means an amount of a compound, or a pharmaceutically acceptable salt thereof, sufficient to prevent the development of or to alleviate to some extent one or more of the symptoms of the condition or disorder being treated when administered alone or in conjunction with another therapeutic agent for treatment in a particular subject or subject population. The “therapeutically effective amount” may vary depending on the compound, the disease and its severity, and the age, weight, health, etc., of the subject to be treated. For example in a human or other mammal, a therapeutically effective amount may be determined experimentally in a laboratory or clinical setting, or may be the amount required by the guidelines of the United States Food and Drug Administration, or equivalent foreign agency, for the particular disease and subject being treated.
The term “subject” is defined herein to refer to animals such as mammals, including, but not limited to, primates (e.g., humans), cows, sheep, goats, pigs, horses, dogs, cats, rabbits, rats, mice and the like. In one embodiment, the subject is a human. The terms “human,” “patient,” and “subject” are used interchangeably herein.

Compounds of the present disclosure may exist as atropisomers, resulting from hindered rotation about a single bond, when energy differences due to steric strain or other contributors create a barrier to rotation that is high enough to allow for isolation of individual conformers. See, e.g., Bringmann, G. et al., Atroposelective Synthesis of Axially Chiral Biaryl Compounds. Angew. Chem., Int. Ed., 2005, 44: 5384-5428. In some instances, the barrier of rotation is high enough that the different atropisomers may be separated and isolated, such as by chromatography on a chiral stationary phase. It is to be understood that the stereochemistry of the atropisomers is included in the compound names only when compounds are assayed as being pure (at least 95%) or are predominantly (at least 80%) one isomer. Where there is no atropisomer stereochemistry noted for a compound, then it is to be understood that either the stereochemistry is undetermined, or it was determined to be a near-equal mixture of atropisomers. In addition, where there is a discrepancy between the name of the compound and the structure found in Table 1, the structure depicted in Table 1 shall prevail.
Compounds of the present disclosure may exist as stereoisomers wherein asymmetric or chiral centers are present. These stereoisomers are “R” or “S” depending on the configuration of substituents around the chiral carbon atom. The terms “R” and “S” used herein are configurations as defined in IUPAC 1974 Recommendations for Section E, Fundamental Stereochemistry, in Pure Appl. Chem., 1976, 45: 13-30. The present disclosure contemplates various stereoisomers and mixtures thereof and these are specifically included within the scope of this present disclosure. Stereoisomers include enantiomers and diastereomers, and mixtures of enantiomers or diastereomers. Individual stereoisomers of compounds of the present disclosure may be prepared synthetically from commercially available starting materials which contain asymmetric or chiral centers or by preparation of racemic mixtures followed by methods of resolution well-known to those of ordinary skill in the art. These methods of resolution are exemplified by (1) attachment of a mixture of enantiomers to a chiral auxiliary, separation of the resulting mixture of diastereomers by precipitation or chromatography and optional liberation of the optically pure product from the auxiliary as described in Furniss, Hannaford, Smith, and Tatchell, “Vogel's Textbook of Practical Organic Chemistry”, 5th edition (1989), Longman Scientific & Technical, Essex CM20 2JE, England, or (2) direct separation of the mixture of optical enantiomers on chiral chromatographic columns or (3) fractional recrystallization methods.
Compounds of the present disclosure may exist as cis or trans isomers, wherein substituents on a ring may attached in such a manner that they are on the same side of the ring (cis) relative to each other, or on opposite sides of the ring relative to each other (trans). For example, cyclobutane may be present in the cis or trans configuration, and may be present as a single isomer or a mixture of the cis and trans isomers. Individual cis or trans isomers of compounds of the present disclosure may be prepared synthetically from commercially available starting materials using selective organic transformations, or prepared in single isomeric form by purification of mixtures of the cis and trans isomers. Such methods are well-known to those of ordinary skill in the art, and may include separation of isomers by precipitation or chromatography.
It should be understood that the compounds of the disclosure may possess tautomeric forms, as well as geometric isomers, and that these also constitute an aspect of the disclosure.
The present disclosure includes all pharmaceutically acceptable isotopically-labeled compounds of Formula (I) wherein one or more atoms are replaced by atoms having the same atomic number, but an atomic mass or mass number different from the atomic mass or mass number which predominates in nature. Examples of isotopes suitable for inclusion in the compounds of the disclosure include isotopes of hydrogen, such as 2H and 3H, carbon, such as 11C, 13C and 14C, chlorine, such as 36Cl, fluorine, such as 18F, iodine, such as 123I and 125I, nitrogen, such as 13N and 15N, oxygen, such as 15O, 17O and 18O, phosphorus, such as 32P, and sulphur, such as 31S. Certain isotopically-labeled compounds of Formula (I), for example, those incorporating a radioactive isotope, are useful in drug and/or substrate tissue distribution studies. The radioactive isotopes tritium, i.e. 3H, and carbon-14, i.e. 14C, are particularly useful for this purpose in view of their ease of incorporation and ready means of detection. Substitution with heavier isotopes such as deuterium, i.e. 2H, may afford certain therapeutic advantages resulting from greater metabolic stability, for example, increased in vivo half-life or reduced dosage requirements, and hence may be preferred in some circumstances. Substitution with positron emitting isotopes, such as 11C, 18F, 15O and 13N, can be useful in Positron Emission Topography (PET) studies for examining substrate receptor occupancy. Isotopically-labeled compounds of Formula (I) may generally be prepared by conventional techniques known to those skilled in the art or by processes analogous to those described in the accompanying Examples using an appropriate isotopically-labeled reagents in place of the non-labeled reagent previously employed.
Thus, the formula drawings within this specification can represent only one of the possible tautomeric, geometric, or stereoisomeric forms. It is to be understood that the present disclosure encompasses any tautomeric, geometric, or stereoisomeric form, and mixtures thereof, and is not to be limited merely to any one tautomeric, geometric, or stereoisomeric form utilized within the formula drawings.
Exemplary compounds of Formula (I) include, but are not limited to, the compounds shown in Table 1 below. It is to be understood that when there is a discrepancy between the name of the compound found herein and the structure found in Table I, the structure in Table 1 shall prevail. In addition, it is to be understood that an asterisk (*), at a particular stereocenter in a structure, indicates an arbitrary assignment of stereochemical configuration at that stereocenter.

General Procedure For Solid-Phase Peptide Synthesis (SPPS)
Peptides were synthesized with, at most, 250 μmol preloaded Wang resin/vessel on an ABI 433A peptide synthesizer using 250 μmol scale Fastmoc™ coupling cycles. Preloaded cartridges containing 1 mmol standard Fmoc-amino acids, except for the position of attachment of the fluorophore, where 1 mmol Fmoc-Lys(Mtt)—OH was placed in the cartridge, were used with conductivity feedback monitoring. N-terminal acetylation was accomplished by using 1 mmol acetic acid in a cartridge under standard coupling conditions.
Removal Of 4-Methyltrityl (Mtt) From Lysine
The resin from the synthesizer was washed thrice with dichloromethane and kept wet. 150 mL of 95:4:1 dichloromethane:triisopropylsilane:trifluoroacetic acid was flowed through the resin bed over 30 minutes. The mixture turned deep yellow then faded to pale yellow. 100 mL of N,N-dimethylformamide (DMF) was flowed through the bed over 15 minutes. The resin was then washed thrice with DMF and filtered. Ninhydrin tests showed a strong signal for primary amine.
Resin Labeling With 6-Carboxyfluorescein-NHS (6-FAM-NHS)
The resin was treated with 2 equivalents 6-FAM-NHS in 1% DIEA/DMF and stirred or shaken at ambient temperature overnight. When complete, the resin was drained, washed thrice with DMF, thrice with (1×dichloromethane and 1×methanol) and dried to provide an orange resin that was negative by ninhydrin test.
General Procedure For Cleavage And Deprotection Of Resin-Bound
Peptide
Peptides were cleaved from the resin by shaking for 3 hours at ambient temperature in a cleavage cocktail consisting of 80% TFA, 5% water, 5% thioanisole, 5% phenol, 2.5% TIS, and 2.5% EDT (1 mL/0.1 g resin). The resin was removed by filtration and rinsing twice with TFA. The TFA was evaporated from the filtrates, and product was precipitated with ether (10 mL/0.1 g resin), recovered by centrifugation, washed twice with ether (10 mL/0.1 g resin) and dried to give the crude peptide.
General Procedure For Purification Of Peptides
The crude peptides were purified on a Gilson preparative HPLC system running Unipoint® analysis software (Gilson, Inc., Middleton, WI) on a radial compression column containing two 25×100 mm segments packed with Delta-Pak™ C18 15 μm particles with 100 Å pore size and eluted with one of the gradient methods listed below. One to two milliliters of crude peptide solution (10 mg/mL in 90% DMSO/water) was purified per injection. The peaks containing the product(s) from each run were pooled and lyophilized. All preparative runs were run at 20 mL/minute with eluents as buffer A: 0.1% TFA-water and buffer B: acetonitrile.
General Procedure For Analytical HPLC
Analytical HPLC was performed on a Hewlett-Packard 1200 series system with a diode-array detector and a Hewlett-Packard 1046A fluorescence detector running HPLC 3D ChemStation software version A.03.04 (Hewlett-Packard. Palo Alto, CA) on a 4.6×250 mm YMC column packed with ODS-AQ 5 μm particles with a 120 Å pore size and eluted with one of the gradient methods listed below after preequilibrating at the starting conditions for 7 minutes. Eluents were buffer A: 0.1% TFA-water and buffer B: acetonitrile. The flow rate for all gradients was 1 mL/minute.
Synthesis of Probe F-Bak
Peptide probe F-bak, which binds MCL-1, was synthesized as described below. Probe F-Bak is acetylated at the N-terminus, amidated at the C-terminus and has the amino acid sequence GQVGRQLAIIGDKINR (SEQ ID NO:1). It is fluoresceinated at the lysine residue (K) with 6-FAM. Probe F-Bak can be abbreviated as follows: acetyl-GQVGRQLAIIGDK(6-FAM)INR—NH2.
To make probe F-Bak, Fmoc-Rink amide MBHA resin was extended using the general peptide synthesis procedure to provide the protected resin-bound peptide (1.020 g). The Mtt group was removed, labeled with 6-FAM-NHS and cleaved and deprotected as described hereinabove to provide the crude product. This product was purified by RP-HPLC. Fractions across the main peak were tested by analytical RP-HPLC, and the pure fractions were isolated and lyophilized, with the major peak providing the title compound. MALDI-MS m/z=2137.1 [(M+H)+].
Alternative Synthesis of Peptide Probe F-Bak
In an alternative method, the protected peptide was assembled on 0.25 mmol Fmoc-Rink amide MBHA resin (Novabiochem) on an Applied Biosystems 433A automated peptide synthesizer running Fastmoc™ coupling cycles using pre-loaded 1 mmol amino acid cartridges, except for the fluorescein(6-FAM)-labeled lysine, where 1 mmol Fmoc-Lys(4-methyltrityl) was weighed into the cartridge. The N-terminal acetyl group was incorporated by putting 1 mmol acetic acid in a cartridge and coupling as described hereinabove. Selective removal of the 4-methyltrityl group was accomplished with a solution of 95:4:1 DCM:TIS:TFA (v/v/v) flowed through the resin over 15 minutes, followed by quenching with a flow of dimethylformamide. Single-isomer 6-carboxyfluorescein-NHS was reacted with the lysine side-chain in 1% DIEA in DMF and confirmed complete by ninhydrin testing. The peptide was cleaved from the resin and side-chains deprotected by treating with 80:5:5:5:2.5:2.5 TFA/water/phenol/thioanisole/triisopropylsilane: 3,6-dioxa-1,8-octanedithiol (v/v/v/v/v/v), and the crude peptide was recovered by precipitation with diethyl ether. The crude peptide was purified by reverse-phase high-performance liquid chromatography, and its purity and identity were confirmed by analytical reverse-phase high-performance liquid chromatography and matrix-assisted laser-desorption mass-spectrometry (m/z=2137.1 ((M+H)+).
Time Resolved-Fluorescence Resonance Energy Transfer (TR-FRET) Assay
The ability of exemplary MCL-1 inhibitors Example 1 to Example 178 to compete with probe F-Bak for binding MCL-1 was demonstrated using a Time Resolved Fluorescence Resonance Energy Transfer (TR-FRET) binding assay.
Method
For the assay, an acoustic dispenser was used to prepare dilution series from 10 mM test compounds in 100% DMSO and directly transfer 160 nL into low volume 384-well assay plates. 8 μL of a protein/probe/antibody mix was then added to each well resulting in final concentrations listed below: Test compound: 11 three-fold dilutions beginning at 25 μM
The samples were then mixed on a shaker for 1 minute and incubated for an additional 2 hours at room temperature. For each assay plate, a probe/antibody and protein/antibody/probe mixture were included as a negative and a positive control, respectively. Fluorescence was measured on the Envision (Perkin Elmer) using a 340/35 nm excitation filter and 520/525 (F-Bak) and 495/510 nm (Tb-labeled anti-his antibody) emission filters. Dissociation constants (Ki) were determined using Wang's equation (Wang, 1995, FEBS Lett. 360:111-114). The TR-FRET assay can be performed in the presence of varying concentrations of human serum (HS) or fetal bovine serum (FBS). Compounds were tested both without HS and in the presence of 10% HS.
Results
The results of binding assays (K1 in nanomolar) are provided in Table 2, below, and demonstrate the ability of compounds of the disclosure to bind MCL-1 protein.
The in vitro efficacy of exemplary MCL-1 inhibitors can be determined in cell-based killing assays using a variety of cell lines and mouse tumor models. For example, their activity on cell viability can be assessed on a panel of cultured tumorigenic and non-tumorigenic cell lines, as well as primary mouse or human cell populations. MCL-1 inhibitory activity of exemplary MCL-1 inhibitors was confirmed in a cell viability assay with AMO-1 and NCI-H929 human multiple myeloma tumor cell lines.
Method
In one exemplary set of conditions, NCI-H929 or AMO-1 (ATCC, Manassas, VA) were plated 4,000 cells per well in 384-well tissue culture plates (Corning, Corning, NY) in a total volume of 25 μL RPMI tissue culture medium supplemented with 10% fetal bovine serum (Sigma-Aldrich, St. Louis, MO) and treated with a 3-fold serial dilution of the compounds of interest with a Labcyte Echo from a final concentration of 10 μM to 0.0005 μM. Each concentration was tested in duplicate at least 3 independent times. A luminescent signal proportional to the number of viable cells following 24 hours of compound treatment was determined using the CellTiter-Glo® Luminescent Cell Viability Assay according to the manufacturer's recommendations (Promega Corp., Madison, WI). The plates were read in a Perkin Elmer Envision using a Luminescence protocol. To generate dose response curves the data is normalized to percent viability by setting the averages of the staurosporine (10 uM) and DMSO only control wells to 0% and 100% viability respectively. The IC50 values for the compounds are generated by fitting the normalized data with Accelrys Assay Explorer 3.3 to a sigmoidal curve model using linear regression, Y=(100*xn)/(Kn+xn), where Y is the measured response, x is the compound concentration, n is the Hill Slope and K is the IC50 and the lower and higher asymptotes are constrained to 0 and 100 respectively.
Results
The results of AMO-1 and H929 cell viability assays (IC50 in nanomolar) carried out in the presence of 10% FBS for exemplary MCL-1 inhibitors are provided in Table 3, below. The results demonstrate the ability of compounds of the disclosure to potently inhibit the growth of human tumor cells in vitro.
The ability of certain exemplary compounds of the present disclosure to inhibit the growth of tumor cells in mice was demonstrated in xenograft models derived from a human multiple myeloma cell line, AMO-1.
AMO-1 cells were obtained from the Deutsche Sammlung von Microorganismen und Zellkulturen (DSMZ, Braunschweig, Germany). The cells were cultured as monolayers in RPMI-1640 culture media (Invitrogen, Carlsbad, CA) that was supplemented with 10% Fetal Bovine Serum (FBS, Hyclone, Logan, UT). To generate xenografts, 5×106 viable cells were inoculated subcutaneously into the right flank of immune deficient female SCID/bg mice (Charles River Laboratories, Wilmington, MA) respectively. The injection volume was 0.2 mL and composed of a 1:1 mixture of S MEM and Matrigel (BD, Franklin Lakes, NJ). Tumors were size matched at approximately 200 mm3. MCL-1 inhibitors were formulated in 5% DMSO, 20% cremaphor EL and 75% D5W for injection and injected intraperitoneally. Injection volume did not exceed 200 μL. Alternatively, MCL-1 inhibitors were formulated in 5% DMSO, 10% cremaphor and 85% D5W for injection and injected intravenously. Injection volume did not exceed 200 □L. Therapy began within 24 hours after size matching of the tumors. Mice weighed approximately 21 g at the onset of therapy. Tumor volume was estimated two to three times weekly. Measurements of the length (L) and width (W) of the tumor were taken via electronic caliper and the volume was calculated according to the following equation: V=L×W2/2. Mice were euthanized when tumor volume reached 3,000 mm3 or skin ulcerations occurred. Seven or eight mice were housed per cage. Food and water were available ad libitum. Mice were acclimated to the animal facilities for a period of at least one week prior to commencement of experiments. Animals were tested in the light phase of a 12-hour light: 12-hour dark schedule (lights on at 06:00 hours).
To refer to efficacy of therapeutic agents, parameters of amplitude (TGImax), durability (TGD) of therapeutic response are used. TGImax is the maximum tumor growth inhibition during the experiment. Tumor growth inhibition is calculated by 100*(1-Tv/Cv) where Tv and Cv are the mean tumor volumes of the treated and control groups, respectively. TGD or tumor growth delay is the extended time of a treated tumor needed to reach a volume of 1 cm3 relative to the control group. TGD is calculated by 100*(Tt/Ct-1) where Tt and Ct are the median time periods to reach 1 cm3 of the treated and control groups, respectively.
Results
As shown in Tables 4-6, compounds of the present disclosure are efficacious in an in vivo AMO-1 xenograft model of multiple myeloma, showing significant tumor growth inhibition and tumor growth delay after intraperitoneal (IP) or intravenous (IV) doses of drug.
