FIELD OF THE INVENTION
This invention pertains to compounds which inhibit the activity of Bcl-xL anti-apoptotic proteins, compositions containing the compounds, and methods of treating diseases during which anti-apoptotic Bcl-xL proteins are expressed.
BACKGROUND OF THE INVENTION
Apoptosis is recognized as an essential biological process for tissue homeostasis of all living species. In mammals in particular, it has been shown to regulate early embryonic development. Later in life, cell death is a default mechanism by which potentially dangerous cells (e.g., cells carrying cancerous defects) are removed. Several apoptotic pathways have been uncovered, and one of the most important involves the Bcl-2 family of proteins, which are key regulators of the mitochondrial (also called “intrinsic”) pathway of apoptosis. See, Danial, N. N. and Korsmeyer, S. J. Cell (2004) 116, 205-219. The structural homology domains BH1, BH2, BH3 and BH4 are characteristic of this family of proteins. The Bcl-2 family of proteins can be further classified into three subfamilies depending on how many of the homology domains each protein contains and on its biological activity (i.e., whether it has pro- or anti-apoptotic function).
The first subgroup contains proteins having all 4 homology domains, i.e., BH1, BH2, BH3 and BH4. Their general effect is anti-apoptotic, that is to preserve a cell from starting a cell death process. Proteins such as, for example, Bcl-2, Bcl-w, Bcl-xL, Mcl-1 and Bfl-1/A1 are members of this first subgroup. Proteins belonging to the second subgroup contain the three homology domains BH1, BH2 and BH3, and have a pro-apoptotic effect. The two main representative proteins of this second subgroup are Bax and Bak. Finally, the third subgroup is composed of proteins containing only the BH3 domain and members of this subgroup are usually referred to as “BH3-only proteins.” Their biological effect on the cell is pro-apoptotic. Bim, Bid, Bad, Bik, Noxa, Hrk, Bmf, and Puma are examples of this third subfamily of proteins. The exact mechanism by which the Bcl-2 family proteins regulate cell death is still not entirely known and understanding this mechanism is an active area of research in the science community. In one hypothesis of regulation of cell death by Bcl-2 family proteins, the BH3-only proteins are further categorized as either “activator” (e.g., Bim and Bid) or “sensitizer” (e.g., Bad, Bik, Noxa, Hrk, Bmf, and Puma) proteins depending on their regulatory function.
The key to tissue homeostasis is achieving the delicate balance in the interactions among the three subgroups of protein in cells. Recent studies have tried to elucidate the mechanisms by which pro-apoptotic and anti-apoptotic subgroups of Bcl-2 family proteins interact to allow a cell to undergo programmed cell death. After receiving intra- or extra-cellular signals in cells, post-translational or transcriptional activation of BH3-only proteins occurs. The BH3-only proteins are the primary inducers of an apoptotic cascade that includes, as one step, the activation of the pro-apoptotic proteins Bax and Bak on the mitochondrial membrane in cells. Upon activation of Bax and/or Bak that are either already anchored to the mitochondrial membrane or migrate to this membrane, Bax and/or Bak oligomerize to result in mitochondrial outer membrane permeabilization (MOMP), the release of cytochrome C, and downstream activation of effector caspases, to ultimately result in cell apoptosis. Some researchers hypothesize that certain BH3-only proteins (e.g., Puma, Bim, Bid) are “activators” in that these proteins directly engage pro-apoptotic proteins Bax and Bak to initiate MOMP, while other BH3-only proteins (e.g., Bad, Bik and Noxa) are “sensitizers” and induce Bax and Bak oligomerization indirectly by binding anti-apoptotic proteins (e.g., Bcl-2, Bcl-xL, Bcl-w, Mcl-1) and displacing and “freeing-up” the “activator” BH3-only proteins, which subsequently bind to and activate pro-apoptotic proteins (e.g., Bax, Bak) to induce cell death. Other researchers suggest that anti-apoptotic proteins engage and seqeuester Bax and Bak directly and all BH3-only proteins regulates this interaction by binding to anti-apoptotic proteins (e.g., Bcl-2, Bcl-xL, Bcl-w, Mcl-1) which results in the release Bax and Bak. See, Adams, J. M. and Cory S. Oncogene (2007) 26, 1324-1337; Willis, S. N. et al. Science (2007) 315, 856-859. Although the exact interactions through which the anti- and pro-apoptotic Bcl-2 family proteins regulate apoptosis remain under debate, there is a large body of scientific evidence to show that compounds which inhibit the binding of BH3-only proteins to anti-apoptotic Bcl-2 family proteins promote apoptosis in cells.
Dysregulated apoptotic pathways have been implicated in the pathology of many significant diseases such as neurodegenerative conditions (up-regulated apoptosis), such as for example, Alzheimer's disease; and proliferative diseases (down-regulated apoptosis) such as for example, cancer, autoimmune diseases and pro-thrombotic conditions.
In one aspect, the implication that down-regulated apoptosis (and more particularly the Bcl-2 family of proteins) is involved in the onset of cancerous malignancy has revealed a novel way of targeting this still elusive disease. Research has shown, for example, the anti-apoptotic proteins, Bcl-2 and Bcl-xL, are over-expressed in many cancer cell types. See, Zhang J. Y., Nature Reviews/Drug Discovery, (2002) 1, 101; Kirkin, V. et al. Biochimica et Biophysica Acta (2004) 1644, 229-249; and Amundson, S. A. et al. Cancer Research (2000) 60, 6101-6110. The effect of this deregulation is the survival of altered cells which would otherwise have undergone apoptosis in normal conditions. The repetition of these defects associated with unregulated proliferation is thought to be the starting point of cancerous evolution. Additionally, research has shown that BH3-only proteins can act as tumor suppressors when expressed in diseased animals.
These findings as well as numerous others have made possible the emergence of new strategies in drug discovery for targeting cancer. If a small molecule that could mimic the effect of BH3-only proteins were able to enter the cell and overcome the anti-apoptotic protein over-expression, then it could be possible to reset the apoptotic process. This strategy can have the advantage that it can alleviate the problem of drug resistance which is usually a consequence of apoptotic deregulation (abnormal survival).
Researchers also have demonstrated that platelets also contain the necessary apoptotic machinery (e.g., Bax, Bak, Bcl-xL, Bcl-2, cytochrome c, caspase-9, caspase-3 and APAF-1) to execute programmed cell death through the intrinsic apoptotic pathway. Although circulating platelet production is a normal physiological process, a number of diseases are caused or exacerbated by excess of, or undesired activation of, platelets. The above suggests that therapeutic agents capable of inhibiting anti-apoptotic proteins in platelets and reducing the number of platelets in mammals maybe useful in treating pro-thrombotic conditions and diseases that are characterized by an excess of, or undesired activation of, platelets.
We have developed a class of small molecule BH3-only protein mimetics, i.e., ABT-737 and ABT-263, that bind strongly to a subset of anti-apoptotic Bcl-2 proteins including Bcl-2, Bcl-w and Bcl-xL, but only weakly to Mcl-1 and A1, and exhibits mechanism-based cytotoxicity. These compounds were tested in animal studies and demonstrated cytotoxic activity in certain xenograft models as single agents, as well as enhanced the effects of a number of chemotherapeutic agents on other xenograft models when used in combination. See, Tse, C. et al. Cancer Res (2008) 68, 3421-3428; and van Delft, M. F. et al. Cancer Cell (2006) 10, 389-399. These in vivo studies suggest the potential utility of inhibitors of anti-apoptotic Bcl-2 family proteins for the treatment of diseases that involve a dysregulated apoptotic pathway.
The natural expression levels of anti-apoptotic Bcl-2 family proteins members vary in different cell types. For example, in young platelets, Bcl-xL protein is highly expressed and plays an important role in regulating cell death (life span) of platelets. Also, in certain cancer cell types, the cancer cell's survival is attributed to the dysregulation of the apoptotic pathway caused by the over-expression of one or more anti-apoptotic Bcl-2 protein family members. In view of the important role for Bcl-2 family of proteins in regulating apoptosis in both cancerous and normal (i.e., non-cancerous) cells, and the recognized inter-cell type variability of Bcl-2 family protein expression, it is advantageous to have a small molecule inhibitor that selectively targets and preferably binds to one type or a subset of anti-apoptotic Bcl-2 protein(s), for example, to an anti-apoptotic Bcl-2 family member that overexpressed in a certain cancer type. Such a selective compound also may confer certain advantages in the clinical setting, by providing, for example, the flexibility to select a dosing regimen, a reduced on-target toxic effect in normal cells, among others (e.g., lymphopenia has been observed in Bcl-2 deficient mice). See, Nakayama, K. et al. PNAS (1994) 91, 3700-3704.
In view of the above, there is a need in the art for small molecules therapeutics that can selectively inhibit the activity of one type or a subset of anti-apoptotic Bcl-2 proteins, for example, of a Bcl-xL anti-apoptotic protein. The present invention fulfills at least this need.

DETAILED DESCRIPTION OF THE INVENTION
Abbreviations and Definitions
Unless otherwise defined herein, scientific and technical terms used in connection with the present invention shall have the meanings that are commonly understood by those of ordinary skill in the art. The meaning and scope of the terms should be clear, however, in the event of any latent ambiguity, definitions provided herein take precedent over any dictionary or extrinsic definition. In this application, the use of “or” means “and/or” unless stated otherwise. Furthermore, the use of the term “including”, as well as other forms, such as “includes” and “included”, is not limiting. With reference to the use of the words “comprise” or “comprises” or “comprising” in this patent application (including the claims), Applicants note that unless the context requires otherwise, those words are used on the basis and clear understanding that they are to be interpreted inclusively, rather than exclusively, and that Applicants intend each of those words to be so interpreted in construing this patent application, including the claims below. For a variable that occurs more than one time in any substituent or in the compound of the invention or any other formulae herein, its definition on each occurrence is independent of its definition at every other occurrence. Combinations of substituents are permissible only if such combinations result in stable compounds. Stable compounds are compounds which can be isolated in a useful degree of purity from a reaction mixture.
It is meant to be understood that proper valences are maintained for all combinations herein, that monovalent moieties having more than one atom are attached through their left ends, and that divalent moieties are drawn from left to right.
As used in the specification and the appended claims, unless specified to the contrary, the following terms have the meaning indicated:
The term “alkyl” (alone or in combination with another term(s)) means a straight- or branched-chain saturated hydrocarbyl substituent typically containing from 1 to about 10 carbon atoms; or in another embodiment, from 1 to about 8 carbon atoms; in another embodiment, from 1 to about 6 carbon atoms; and in another embodiment, from 1 to about 4 carbon atoms. Examples of such substituents include methyl, ethyl, n-propyl, isopropyl, n-butyl, isobutyl, sec-butyl, tert-butyl, pentyl, iso-amyl, and hexyl and the like.
The term “alkenyl” (alone or in combination with another term(s)) means a straight- or branched-chain hydrocarbyl substituent containing one or more double bonds and typically from 2 to about 10 carbon atoms; or in another embodiment, from 2 to about 8 carbon atoms; in another embodiment, from 2 to about 6 carbon atoms; and in another embodiment, from 2 to about 4 carbon atoms. Examples of such substituents include ethenyl (vinyl), 2-propenyl, 3-propenyl, 1,4-pentadienyl, 1,4-butadienyl, 1-butenyl, 2-butenyl, and 3-butenyl and the like.
The term “alkynyl” (alone or in combination with another term(s)) means a straight- or branched-chain hydrocarbyl substituent containing one or more triple bonds and typically from 2 to about 10 carbon atoms; or in another embodiment, from 2 to about 8 carbon atoms; in another embodiment, from 2 to about 6 carbon atoms; and in another embodiment, from 2 to about 4 carbon atoms. Examples of such substituents include ethynyl, 2-propynyl, 3-propynyl, 2-butynyl and 3-butynyl and the like.
The term “carbocyclyl” (alone or in combination with another term(s)) means a saturated cyclic (i.e., “cycloalkyl”), partially saturated cyclic (i.e., “cycloalkenyl”), or completely unsaturated (i.e., “aryl”) hydrocarbyl substituent containing from 3 to 14 carbon ring atoms (“ring atoms” are the atoms bound together to form the ring or rings of a cyclic substituent). A carbocyclyl may be a single-ring (monocyclic) or polycyclic ring structure.
A carbocyclyl may be a single ring structure, which typically contains from 3 to 8 ring atoms, more typically from 3 to 6 ring atoms, and even more typically 5 to 6 ring atoms. Examples of such single-ring carbocyclyls include cyclopropyl (cyclopropanyl), cyclobutyl (cyclobutanyl), cyclopentyl (cyclopentanyl), cyclopentenyl, cyclopentadienyl, cyclohexyl (cyclohexanyl), cyclohexenyl, cyclohexadienyl, cyclooxtanyl, and phenyl. A carbocyclyl may alternatively be polycyclic (i.e., may contain more than one ring). Examples of polycyclic carbocyclyls include bridged, fused, and spirocyclic carbocyclyls. In a spirocyclic carbocyclyl, one atom is common to two different rings. Examples of spirocyclic carbocyclyls include spiropentanyl, spiro[3.5]nonanyl, and spiro[2.5]octanyl. In a bridged carbocyclyl, the rings share at least two common non-adjacent atoms. Examples of bridged carbocyclyls include bicyclo[2.2.1]heptanyl, bicyclo[2.2.1]hept-2-enyl, and adamantanyl (tricyclo[3.3.1.13,7]decanyl). In a fused-ring carbocyclyl system, two or more rings may be fused together, such that two rings share one common bond. Examples of two- or three-fused ring carbocyclyls include naphthalenyl, tetrahydronaphthalenyl (tetralinyl), indenyl, indanyl (dihydroindenyl), anthracenyl, phenanthrenyl, and decalinyl.
The term “cycloalkyl” (alone or in combination with another term(s)) means a saturated cyclic hydrocarbyl substituent containing from 3 to 14 carbon ring atoms. A cycloalkyl may be a single carbon ring, which typically contains from 3 to 8 carbon ring atoms and more typically from 3 to 6 ring atoms. Examples of single-ring cycloalkyls include cyclopropyl, cyclobutyl, cyclopentyl, cyclohexyl, cycloheptanyl, and cyclooctanyl. A cycloalkyl may alternatively be polycyclic or contain more than one ring. Examples of polycyclic cycloalkyls include bridged, fused, and spirocyclic carbocyclyls. Examples of bridged cycloalkyls include adamantanyl(tricyclo[3.3.1.13,7]decanyl), and bicyclo[3.1.1]heptanyl.
The term “Cx-Cy cycloalkyl” means a cycloalkyl ring system containing from x to y carbon atoms. For example “C3-C7 cycloalkyl” means a cycloalkyl ring system containing from 3 to 7 carbon atoms.
The term “cycloalkenyl” (alone or in combination with another term(s)) means a partially saturated cyclic hydrocarbyl substituent containing from 3 to 14 carbon ring atoms. A cycloalkenyl may be a single carbon ring, which typically contains from 3 to 8 carbon ring atoms and more typically from 4 to 6 ring atoms. Examples of single-ring cycloalkenyls include cyclopentenyl, and cyclohexenyl. A cycloalkenyl may alternatively be polycyclic or contain more than one ring. Examples of polycyclic cycloalkenyls include bridged, fused, and spirocyclic carbocyclyls. Examples of bridged cycloalkenyls include bicyclo[2.2.1]hept-2-enyl.
The term “Cx-Cy cycloalkenyl” means a cycloalkenyl ring system containing from x to y carbon atoms. For example “C4-C7 cycloalkenyl” means a cycloalkenyl ring system containing from 4 to 7 carbon atoms.
The term “aryl” (alone or in combination with another term(s)) means an aromatic carbocyclyl containing from 6 to 14 carbon ring atoms. An aryl may be monocyclic or polycyclic (i.e., may contain more than one ring). In the case of polycyclic aromatic rings, only one ring the polycyclic system is required to be unsaturated while the remaining ring(s) may be saturated, partially saturated or unsaturated. Examples of aryls include phenyl, naphthalenyl, indenyl, indanyl, and tetrahydronaphthyl.
The term “heteroarylene” means a divalent heteroarene.
The term “arylene” means a divalent arene.
The term “phenylene” means a divalent benzene.
In some instances, the number of carbon atoms in a substituent (e.g., alkyl, alkenyl, alkynyl, cycloalkyl, heterocyclyl, heteroaryl, and aryl) is indicated by the prefix “Cx-Cy-”, wherein x is the minimum and y is the maximum number of carbon atoms. Thus, for example, “C1-C6-alkyl” refers to an alkyl containing from 1 to 6 carbon atoms. Illustrating further, “C3-C8-cycloalkyl” means a saturated hydrocarbyl ring containing from 3 to 8 carbon ring atoms.
The term “Cx-y branched chain alkyl” means a saturated hydrocarbyl substituent containing from x to y carbons wherein attachment occurs through a dialkyl trivalent- or trialkyl tetravalent-carbon radical. Examples of such substituents include isopentanyl (pentan-3-yl), neopentanyl(2,2-dimethylpropan-2-yl), heptan-4-yl, and 2,6-dimethylheptan-4-yl.
The term, “C3-11 branched chain alkyl” means a saturated hydrocarbyl substituent containing from 3 to 11 carbons wherein attachment occurs through a dialkyl trivalent- or trialkyl tetravalent-carbon radical.
The term “hydrogen” (alone or in combination with another term(s)) means a hydrogen radical, and may be depicted as —H.
The term “hydroxy” (alone or in combination with another term(s)) means —OH.
The term “carboxy” (alone or in combination with another term(s)) means —C(O)—OH.
The term “amino” (alone or in combination with another term(s)) means —NH2.
The term “halogen” or “halo” (alone or in combination with another term(s)) means a fluorine radical (which may be depicted as —F), chlorine radical (which may be depicted as —Cl), bromine radical (which may be depicted as —Br), or iodine radical (which may be depicted as —I).
If a substituent is described as being “substituted”, a non-hydrogen radical is in the place of hydrogen radical on a carbon or nitrogen of the substituent. Thus, for example, a substituted alkyl substituent is an alkyl substituent in which at least one non-hydrogen radical is in the place of a hydrogen radical on the alkyl substituent. To illustrate, monofluoroalkyl is alkyl substituted with a fluoro radical, and difluoroalkyl is alkyl substituted with two fluoro radicals. It should be recognized that if there are more than one substitution on a substituent, each non-hydrogen radical may be identical or different (unless otherwise stated).
If a substituent is described as being “optionally substituted”, the substituent may be either (1) not substituted or (2) substituted. If a substituent is described as being optionally substituted with up to a particular number of non-hydrogen radicals, that substituent 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 substituent, whichever is less. Thus, for example, if a substituent 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.
This patent application uses the terms “substituent” and “radical” interchangeably.
The prefix “halo” indicates that the substituent to which the prefix is attached is substituted with one or more independently selected halogen radicals. For example, haloalkyl means an alkyl substituent in which at least one hydrogen radical is replaced with a halogen radical. Examples of haloalkyls include chloromethyl, 1-bromoethyl, fluoromethyl, difluoromethyl, trifluoromethyl, and 1,1,1-trifluoroethyl. It should be recognized that if a substituent is substituted by more than one halogen radical, those halogen radicals may be identical or different (unless otherwise stated).
The prefix “perhalo” indicates that every hydrogen radical on the substituent to which the prefix is attached is replaced with independently selected halogen radicals, i.e., each hydrogen radical on the substituent is replaced with a halogen radical. If all the halogen radicals are identical, the prefix typically will identify the halogen radical. Thus, for example, the term “perfluoro” means that every hydrogen radical on the substituent to which the prefix is attached is substituted with a fluorine radical. To illustrate, the term “perfluoroalkyl” means an alkyl substituent wherein a fluorine radical is in the place of each hydrogen radical.

In a spirocyclic heterocyclyl, one atom is common to two different rings. In a bridged heterocyclyl, the rings share at least two common non-adjacent atoms. Examples of bridged heterocyclyls include 2-oxatricyclo[3.3.1.13,7]decane. In a fused-ring heterocyclyl, two or more rings may be fused together, such that two rings share one common bond.

The term “heterocycloalkyl” (alone or in combination with another term(s)) means a saturated heterocyclyl.
The term “Cx-Cy heterocycloalkyl” means a heterocycloalkyl ring system containing from x to y ring atoms. For example “C3-C7 heterocycloalkyl” means a heterocycloalkyl ring system containing 3 to 7 ring atoms.
The term “heterocycloalkenyl” (alone or in combination with another term(s)) means a partially saturated heterocyclyl.
The term “Cx-Cy heterocycloalkenyl” means a heterocycloalkenyl ring system containing from x to y ring atoms. For example “C3-C7 heterocycloalkenyl” means a heterocycloalkenyl ring system containing from 3 to 7 ring atoms.
The term “heteroaryl” (alone or in combination with another term(s)) means an aromatic heterocyclyl containing from 5 to 14 ring atoms. A heteroaryl may be a single ring or 2 or 3 fused rings. Examples of heteroaryls include 6-membered ring substituents such as pyridyl, pyrazyl, pyrimidinyl, pyridazinyl, and 1,3,5-, 1,2,4- or 1,2,3-triazinyl; 5-membered ring substituents such as triazolyl, pyrrolyl, imidazyl, furanyl, thiophenyl, pyrazolyl, oxazolyl, isoxazolyl, thiazolyl, 1,2,3-, 1,2,4-, 1,2,5-, or 1,3,4-oxadiazolyl and isothiazolyl: 6/5-membered fused ring substituents such as imidazopyrazinyl (including imidazo[1,2-a]pyrazinyl)imidazopyridinyl (including imidazo[1,2-a]pyridinyl), imidazopyridazinyl (including imidazo[1,2-b]pyridazinyl), thiazolopyridinyl (including thiazolo[5,4-c]pyridinyl, thiazolo[5,4-b]pyridinyl, thiazolo[4,5-b]pyridinyl, and thiazolo[4,5-c]pyridinyl), benzo[d]thiazolyl, benzothiofuranyl, benzisoxazolyl, benzoxazolyl, purinyl, and anthranilyl; and 6/6-membered fused rings such as benzopyranyl, quinolinyl, isoquinolinyl, cinnolinyl, quinazolinyl, and benzoxazinyl.

The term “Cx-Cy heteroaryl” means a heteroaryl ring system containing from x to y ring atoms. For example “C5-C6 heteroaryl” means a heteroaryl ring system containing from 5 to 6 ring atoms.
The term “heteroarylene” means a divalent heteroaryl group.
A prefix attached to a multi-component substituent only applies to the first component. To illustrate, the term “alkylcycloalkyl” contains two components: alkyl and cycloalkyl. Thus, the C1-C6-prefix on C1-C6-alkylcycloalkyl means that the alkyl component of the alkylcycloalkyl contains from 1 to 6 carbon atoms; the C1-C6-prefix does not describe the cycloalkyl component. To illustrate further, the prefix “halo” on haloalkyloxyalkyl indicates that only the alkyloxy component of the alkyloxyalkyl substituent is substituted with one or more halogen radicals. If halogen substitution may alternatively or additionally occur on the alkyl component, the substituent would instead be described as “halogen-substituted alkyloxyalkyl” rather than “haloalkyloxyalkyl.” And finally, if the halogen substitution may only occur on the alkyl component, the substituent would instead be described as “alkyloxyhaloalkyl.”

Compounds
Geometric isomers may exist in the present compounds. Compounds of this invention may contain carbon-carbon double bonds or carbon-nitrogen double bonds in the E or Z configuration, wherein the term “E” represents higher order substituents on opposite sides of the carbon-carbon or carbon-nitrogen double bond and the term “Z” represents higher order substituents on the same side of the carbon-carbon or carbon-nitrogen double bond as determined by the Cahn-Ingold-Prelog Priority Rules. The compounds of this invention may also exist as a mixture of “E” and “Z” isomers. Substituents around a cycloalkyl or heterocycloalkyl are sometimes designated as being of cis or trans configuration.
Compounds of this invention may contain asymmetrically substituted carbon atoms in the R or S configuration, in which the terms “R” and “S” are as defined by the IUPAC 1974 Recommendations for Section E, Fundamental Stereochemistry. Pure Appl. Chem. (1976) 45, 13-10. Compounds having asymmetrically substituted carbon atoms with equal amounts of R and S configurations are racemic at those carbon atoms. Atoms with an excess of one configuration over the other are assigned the configuration present in the higher amount, preferably an excess of about 85%-90%, more preferably an excess of about 95%-99%, and still more preferably an excess greater than about 99%. Accordingly, this invention includes racemic mixtures, relative and absolute stereoisomers, and mixtures of relative and absolute stereoisomers.
Isotope Enriched or Labeled Compounds
Compounds of the invention can exist in isotope-labeled or -enriched form containing one or more atoms having an atomic mass or mass number different from the atomic mass or mass number most abundantly found in nature. Isotopes can be radioactive or non-radioactive isotopes. Isotopes of atoms such as hydrogen, carbon, phosphorous, sulfur, fluorine, chlorine, and iodine include, but are not limited to, 2H, 3H, 13C, 14C, 15N, 18O, 32p, 35S, 18F, 36Cl, and 125I. Compounds that contain other isotopes of these and/or other atoms are within the scope of this invention.
In another embodiment, the isotope-labeled compounds contain deuterium (2H), tritium (3H) or 14C isotopes. Isotope-labeled compounds of this invention can be prepared by the general methods well known to persons having ordinary skill in the art. Such isotope-labeled compounds can be conveniently prepared by carrying out the procedures disclosed in the Examples disclosed herein and Schemes by substituting a readily available isotope-labeled reagent for a non-labeled reagent. In some instances, compounds may be treated with isotope-labeled reagents to exchange a normal atom with its isotope, for example, hydrogen for deuterium can be exchanged by the action of a deuteric acid such as D2SO4D2O. In addition to the above, relevant procedures and intermediates are disclosed, for instance, in Lizondo, J et al., Drugs Fat, 21(11), 1116 (1996); Brickner, S J et al., J Med Chem, 39(3), 673 (1996); Mallesham, B et al., Org Lett, 5(7), 963 (200(3); PCT publications WO1997010223, WO2005099353, WO1995007271, WO2006008754; U.S. Pat. Nos. 7,538,189; 7,534,814; 7,531,685; 7,528,131; 7,521,421; 7,514,068; 7,511,013; and US Patent Application Publication Nos. 20090137457; 20090131485; 20090131363; 20090118238; 20090111840; 20090105338; 20090105307; 20090105147; 20090093422; 20090088416; and 20090082471, the methods are hereby incorporated by reference.
The isotope-labeled compounds of the invention may be used as standards to determine the effectiveness of Bcl-xL inhibitors in binding assays. Isotope containing compounds have been used in pharmaceutical research to investigate the in vivo metabolic fate of the compounds by evaluation of the mechanism of action and metabolic pathway of the nonisotope-labeled parent compound (Blake et al. J. Pharm. Sci. 64, 3, 367-391 (1975)). Such metabolic studies are important in the design of safe, effective therapeutic drugs, either because the in vivo active compound administered to the patient or because the metabolites produced from the parent compound prove to be toxic or carcinogenic (Foster et al. Advances in Drug Research Vol. 14, pp. 2-36, Academic press, London, 1985; Kato et al., J. Labelled Comp. Radiopharmaceut., 36(10):927-932 (1995); Kushner et al., Can. J. Physiol. Pharmacol., 77, 79-88 (1999).
In addition, non-radio active isotope containing drugs, such as deuterated drugs called “heavy drugs,” can be used for the treatment of diseases and conditions related to Bcl-xL activity. Increasing the amount of an isotope present in a compound above its natural abundance is called enrichment. Examples of the amount of enrichment include from about 0.5, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 12, 16, 21, 25, 29, 33, 37, 42, 46, 50, 54, 58, 63, 67, 71, 75, 79, 84, 88, 92, 96, to about 100 mol %. Replacement of up to about 15% of normal atom with a heavy isotope has been effected and maintained for a period of days to weeks in mammals, including rodents and dogs, with minimal observed adverse effects (Czajka D M and Finkel A J. Ann. N.Y. Acad. Sci. 1960 84: 770; Thomson J F, Ann. New York Acad. Sci. 1960 84: 736; Czakja D M et al., Am. J. Physiol. 1961 201: 357). Acute replacement of as high as 15%-23% in human fluids with deuterium was found not to cause toxicity (Blagojevic N et al. in “Dosimetry & Treatment Planning for Neutron Capture Therapy”, Zamenhof R, Solares G and Harling O Eds. 1994. Advanced Medical Publishing, Madison Wis. pp. 125-134; Diabetes Metab. 23: 251 (1997)).
Stable isotope labeling of a drug can alter its physico-chemical properties such as pKa and lipid solubility. These effects and alterations can affect the pharmacodynamic response of the drug molecule if the isotopic substitution affects a region involved in a ligand-receptor interaction. While some of the physical properties of a stable isotope-labeled molecule are different from those of the unlabeled one, the chemical and biological properties are the same, with one important exception: because of the increased mass of the heavy isotope, any bond involving the heavy isotope and another atom will be stronger than the same bond between the light isotope and that atom. Accordingly, the incorporation of an isotope at a site of metabolism or enzymatic transformation will slow said reactions potentially altering the pharmacokinetic profile or efficacy relative to the non-isotopic compound.

Examples of BiTE antibodies include adecatumumab (Micromet MT201), blinatumomab (Micromet MT103) and the like. Without being limited by theory, one of the mechanisms by which T-cells elicit apoptosis of the target cancer cell is by exocytosis of cytolytic granule components, which include perforin and granzyme B.
SiRNAs are molecules having endogenous RNA bases or chemically modified nucleotides. The modifications do not abolish cellular activity, but rather impart increased stability and/or increased cellular potency. Examples of chemical modifications include phosphorothioate groups, 2′-deoxynucleotide, 2′-OCH3-containing ribonucleotides, 2′-F-ribonucleotides, 2′-methoxyethyl ribonucleotides, combinations thereof and the like. The siRNA can have varying lengths (e.g., 10-200 bps) and structures (e.g., hairpins, single/double strands, bulges, nicks/gaps, mismatches) and are processed in cells to provide active gene silencing. A double-stranded siRNA (dsRNA) can have the same number of nucleotides on each strand (blunt ends) or asymmetric ends (overhangs). The overhang of 1-2 nucleotides can be present on the sense and/or the antisense strand, as well as present on the 5′- and/or the 3′-ends of a given strand. For example, siRNAs targeting Mcl-1 have been shown to enhance the activity of ABT-263, (i.e., N-(4-(4-((2-(4-chlorophenyl)-5,5-dimethyl-1-cyclohex-1-en-1-yl)methyl)piperazin-1-yl)benzoyl)-4-(((1R)-3-(morpholin-4-yl)-1-((phenylsulfanyl)methyl)propyl)amino)-3-((trifluoromethyl)sulfonyl)benzenesulfonamide) or ABT-737 (i.e., N-(4-(4-(4′-chloro(1,1′-biphenyl)-2-yl)methyl)piperazin-1-yl)benzoyl)-4-(((1R)-3-(dimethylamino)-1-((phenylsulfanyl)methyl)propyl)amino)-3-nitrobenzenesulfonamide) in multiple tumor cell lines (Tse et. al, Cancer Research 2008, 68(9), 3421 and references therein).
Multivalent binding proteins are binding proteins comprising two or more antigen binding sites. Multivalent binding proteins are engineered to have the three or more antigen binding sites and are generally not naturally occurring antibodies. The term “multispecific binding protein” means a binding protein capable of binding two or more related or unrelated targets. Dual variable domain (DVD) binding proteins are tetravalent or multivalent binding proteins binding proteins comprising two or more antigen binding sites. Such DVDs may be monospecific (i.e., capable of binding one antigen) or multispecific (i.e., capable of binding two or more antigens). DVD binding proteins comprising two heavy chain DVD polypeptides and two light chain DVD polypeptides are referred to as DVD Ig's. Each half of a DVD Ig comprises a heavy chain DVD polypeptide, a light chain DVD polypeptide, and two antigen binding sites. Each binding site comprises a heavy chain variable domain and a light chain variable domain with a total of 6 CDRs involved in antigen binding per antigen binding site.

Electrospray mass-spectra (ESI-MS) were recorded on Finnigan SSQ7000 (Finnigan Corp., San Jose, Calif.) in both positive and negative ion mode.
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 FASTMOCTM 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 DCM 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 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×DCM 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, Wis.) on a radial compression column containing two 25×100 mm segments packed with Delta-PakTM 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/min 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, Calif.) on a 4.6×250 mm YMC column packed with ODS-AQ 5 μ 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/min.

    F-Bak: Peptide Probe Acetyl-GQVGRQLAIIGDK(6-FAM)INR—NH2 (SEQ ID NO:1)


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 as an orange solid (0.37 g). 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 (0.0802 g) as a yellow solid; MALDI-MS m/z=2137.1 [(M+H)+].
Alternative Synthesis of Peptide Probe F-Bak: Acetyl-GQVGRQLAIIGDK(6-FAM)INR-NH2 (SEQ ID NO:1)
The protected peptide was assembeled on 0.25 mmol Fmoc-Rink amide MBHA resin (Novabiochem) on an Applied Biosystems 433A automated peptide synthesizer running FASTMOCTM 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 N,N-dimethylformamide 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 measurement of competition of compounds of Formula (I) with F-Bak for a Bcl-2 family protein (Bcl-xL) binding site using a Time Resolved Fluorescence Resonance Energy Transfer (TR-FRET) binding assay:
Test compounds were serially diluted in DMSO starting at 50 M (2× starting concentration; 10% DMSO) and 10 μL transferred into a 384-well plate. Then 10 μL of a protein/probe/antibody mix is added to each well at final concentrations listed in Table 1.

The samples are then mixed on a shaker for 1 minute then 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 plate reader (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, Z.X. An 20 exact mathematical expression for describing competitive binding of two different ligands to protein molecule. FEBS Lett. 1995 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). TR-FRET assay results (Ki, in nanomolar) for representative compounds of Formula (I) are provided below in Table 2.
For comparison, the measurement of the competition of compounds of Formula (I) for other Bcl-2 family protein binding sites (e.g., Bcl-2) using the TR-FRET binding assay was accomplished by substituting GST-Bcl-xL in the TR-FRET assay with other GST-labeled protein, e.g., GST-Bcl-2, prepared in-house.
In one embodiment, compounds of Formula (I) selectively inhibit the Bcl-2 family protein, Bcl-xL, over other Bcl-2 family proteins, such as Bcl-2. For comparison, data (Ki in micromolar) from the measurement of the competition by certain compounds of Formula (I) (i.e., Examples 20, 43, 49, 82, 99, 107, 117, 130, 134, 148 159, 176 and 185 in Table 3) with F-Bak for the Bcl-2 binding site using the TR-FRET binding assay are 0.070, 0.023, 0.039, 0.033, 0.033, 0.056, 0.021, 0.076, 0.024, 0.075, 0.272, 0.177 and 0.014, respectively.
FL5.12 Cellular Assay
The efficacy of the compounds of Formula (I) can also 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. In one exemplary set of conditions, mouse FL5.12 cells transfected with Bcl-XL were cultured under standard conditions in RPMI with 2 mM glutamine, 1% 100 mM sodium pyruvate, 2% 1 M HEPES, 4 μL/L of β-mercaptoethanol, 1% penicillin-streptomycin, 10% FBS, and 10% WEHI-3B conditioned media (for IL-3). For assaying the compound activity, the cells were exchanged into an IL-3-depleted deprivation media, which was identical to the growth media except for the absence of FBS and WEHI-3B conditional media, for 2 days. Then the cells were exchanged to 3% FBS assay media (RPMI with 2 mM glutamine, 1% 100 mM sodium pyruvate, 2% 1 M HEPES, 4 μL/L of β-mercaptoethanol, 1% penicillin-streptomycin, 3% FBS). Compounds in series dilutions were added, and the cells were cultured for 24 hours. Compounds in series dilutions were added, and the cells were cultured for 24 hours. Cell viability was assayed using the CellTiter-Glo assay (Promega Corp., Madison, Wis.) according to the manufacturer instructions. Individual determinations were the result of duplicate values. Cell viability assay results (EC50 in nanomolar) for representative compounds are provided below in Table 2.

Molt-4 Cellular Assay
Molt-4 (ATCC, Manassas, Va.) human acute lymphoblastic leukemia cells were plated 50,000 cells per well in 96-well tissue culture plates in a total volume of 100 μL tissue culture medium supplemented with 10% human serum (Invitrogen, Carlsbad, Calif.) and treated with a 3-fold serial dilution of the compounds of interest from 5 μM to 0.020 μL. Each concentration was tested in duplicate at least 3 separate times. The number of viable cells following 48 hours of compound treatment was determined using the CellTiter 96® Aqueous non-radioactive cell proliferation MTS assay according to manufacturer's recommendations (Promega Corp., Madison, Wis.). Molt-4 cell viability results (i.e. EC50 in micromolar) for certain compounds of Formula (I), (i.e., Examples 81, 82, 84, 87, 124, 130, 134, 145, 151, 152, 166, 179, and 186 in Table 2), are 0.33, 0.135, 0.501, 1.2, 2.7, 0.532, 0.029, 0.081, 0.014, 0.006, 0.586, 0.493, and 0.006, respectively.
Single Dose Pharmacokinetics
The single dose pharmacokinetics of select compounds were evaluated in Sprague-Dawley rats (Charles River) after a 5 mg/kg oral dose (n=3) (10% DMSO in PEG-400) administered by gavage or by 5 mg/kg IV bolus dose (n=3) (10% DMSO in PEG-400). Compound and the internal standard were separated from each other and coextracted contaminants on a 50 mm×3 mm Keystone Betasil CN 5 μm column with an acetonitrile/0.1% trifluoroacetic acid mobile phase (50:50, by volume) at a flow rate of 0.7 mL/min. Analysis was performed on a Sciex API3000 biomolecular mass analyzer with a heated nebulizer interface. Compound and internal standard peak areas were determined using Sciex MacQuan software. The plasma drug concentration of each sample was calculated by least-squares linear regression analysis (nonweighted) of the peak area ratio (parent/internal standard) of the spiked plasma standards versus concentration. The plasma concentration data were submitted to multiexponential curve fitting using WinNonlin.3. The area under the plasma concentration-time curve was calculated using the linear trapezoidal rule for the plasma concentration-time profiles.
In pharmacology, bioavailability (BA) is a subcategory of absorption and is used to describe the fraction of an administered dose of unchanged drug that reaches the systemic circulation, one of the principal pharmacokinetic properties of drugs. By definition, when a medication is administered intravenously, its bioavailability is 100% (see Griffin. J. P. The Textbook of Pharmaceutical Medicine (6th Ed.). New Jersey: BMJ Books). However, when a medication is administered via other routes (such as orally), its bioavailability generally decreases (due to incomplete absorption and first-pass metabolism) and may vary from patient to patient. Bioavailability is one of the essential tools in pharmacokinetics, as bioavailability must be considered when calculating dosages for non-intravenous routes of administration. One way to calculate bioavailability of a drug or agent is by dividing the plasma concentration following an oral dose by the concentration following an intravenous dose. The oral bioavailability (as represented by % F) in Sprague-Dawley rats for representative compounds of the invention are provided below in Table 3.
In the drug discovery setting, it is generally accepted that Lipinski's “rule of 5” predicts that poor oral absorption or poor permeation is likely when two or more of the following metrics are satisfied: i) there are more than 5 hydrogen bond donors, ii) the molecular weight is greater than 500, iii) there are greater than 10 hydrogen bond acceptors (expressed as the sum of nitrogen and oxygen atoms), or iv) the calculated Log P (c Log P) is greater than 5 (Lipinski et al. Adv. Drug Del. Rev. 2001, 3-26). Indeed, the combination of high molecular weight (>500) and high c Log P (>5) is the best predictor of poor absorption or permeation. Compounds described herein generally exceed the recommended ranges pertaining to molecular weight (>500) and c Log P (>5), as shown in Table 3. It is notable, therefore, that Examples described herein have acceptable oral bioavailability in rats (as defined by % F>10, see Martin J. Med. Chem. 2005, 48, 3164), as illustrated in Table 3.

The ability of compounds to kill FL5.12 cells over-expressing Bcl-xL or human tumor cell lines that are dependant upon Bcl-xL such as Molt-4 cells is a direct measure of the compound's ability to inhibit anti-apoptotic Bcl-xL protein function.
