THROMBOPOIETIN ACTIVITY MODULATING COMPOUNDS AND

METHODS

FIELD OF THE INVENTION

[0001] The present invention relates to compounds and methods in the fields of chemistry and medicine. More specifically, the present invention relates to compounds that modulate one or more thrombopoietin activity and/or bind to thrombopoietin receptors, and to methods for making and using such compound.

BACKGROUND

[0002] Thrombopoietin (TPO), also referred to as c-Mpl ligand, rnpl ligand, megapoietin, and megakaryocyte growth and development factor, is a glycoprotein that has been shown to be involved in production of platelets. See e.g., Wendling, F., et. al. _} Biotherapy 10(4):269-77 (1998); Kuter DJ. et al., The Oncologist, 1 :98-106(1996); Metcalf, Nature 369: 519-520 (1994), all of which are incorporated herein by reference in their entirety. TPO has been cloned and its amino acid sequence and the cDNA sequence encoding it have been described. See e.g., U.S. 5,766,581 ; Kuter, D.J. et al., Proc. Natl. Acad. Sci., 91 :11104-11 108 (1994); de Sauvage F.V., et al., Nature, 369: 533-538 (1994); Lok, S. et al., Nature 369:565-568 (1994); Wending, F. et al., Nature, 369: 571-574 (1994), all of which are incorporated herein by reference in their entirety.

[0003] In certain instances, TPO activity results from binding of TPO to the TPO receptor (also called MPL). The TPO receptor has been cloned and its amino acid sequence has been described. See e.g., Vigon et al., Proc. Natl. Acad. Sci., 89:5640-5644 (1992), which is incorporated herein by reference in its entirety.

[0004] In certain instances, TPO modulators may be useful in treating a variety of hematopoietic conditions, including, but not limited to, thrombocytopenia. See e.g., Baser et al. Blood 89:3118-3128 (1997); Fanucchi et al. New Engl. J. Med. 336:404- 409 (1997), both of which are incorporated herein by reference in their entirety. For example, patients undergoing certain chemotherapies, including but not limited to chemotherapy and/or radiation therapy for the treatment of cancer, may have reduced platelet levels. In certain instances, treating such patients with a selective TPO modulator increases platelet levels. In certain instances, selective TPO modulators stimulate production of glial cells, which may result in repair of damaged nerve cells.

[0022] As used herein, the following terms are defined with the following meanings, unless expressly stated otherwise.

[0023] The term "selective binding compound" refers to a compound that selectively binds to any portion of one or more target.

[0024] The term "selective TPO receptor binding compound" refers to a compound that selectively binds to any portion of a TPO receptor.

[0025] The term "selectively binds" refers to the ability of a selective binding compound to bind to a target receptor with greater affinity than it binds to a non-target receptor. In certain embodiments, selective binding refers to binding to a target with an affinity that is at least 10, 50, 100, 250, 500, or 1000 times greater than the affinity for a non-target.

[0026] The term "target receptor" refers to a receptor or a portion of a receptor capable of being bound by a selective binding compound. In certain embodiments, a target receptor is a TPO receptor.

[0027] The term "modulator" refers to a compound that alters an activity. For example, a modulator may cause an increase or decrease in the magnitude of a certain activity compared to the magnitude of the activity in the absence of the modulator. In certain embodiments, a modulator is an inhibitor, which decreases the magnitude of one or more activities. In certain embodiments, an inhibitor completely prevents one or more biological activities. In certain embodiments, a modulator is an activator, which increases the magnitude of at least one activity. In certain embodiments the presence of a modulator results in a activity that does not occur in the absence of the modulator.

[0028] The term "selective modulator" refers to a compound that selectively modulates a target activity.

[0029] The term "selective TPO modulator" refers to a compound that selectively modulates at least one TPO activity. The term selective TPO modulator

includes, but is not limited to "TPO mimic" which refers to a compound, the presence of which results in at least one TPO activity. TPO mimics are described in WO 03/103686A1 and WO 01/21 180, both of which are incorporated herein by reference in their entirety.

[0030] The term "selectively modulates" refers to the ability of a selective modulator to modulate a target activity to a greater extent than it modulates a non-target activity.

[0031] The term "target activity" refers to a biological activity capable of being modulated by a selective modulator. Certain exemplary target activities include, but are not limited to, binding affinity, signal transduction, enzymatic activity, the proliferation and/or differentiation of progenitor cells, generation of platelets, and alleviation of symptoms of a disease or condition.

[0032] The term "TPO activity" refers to a biological activity that results, either directly or indirectly from the presence of TPO. Exemplary TPO activities include, but are not limited to, proliferation and or differentiation of progenitor cells to produce platelets; hematopoiesis; growth and/or development of glial cells; repair of nerve cells; and alleviation of thrombocytopenia.

[0033] The term "thrombocytopenia" refers to a condition wherein the concentration of platelets in the blood of a patient is below what is considered normal for a healthy patient. In certain embodiments, thrombocytopenia is a platelet count less than 450,000, 400,000, 350,000, 300,000, 250,000, 200,000, 150,000, 140,000, 130,000, 120,000, 110,000, 100,000, 75,000, or 50,000 platelets per microliter of blood.

[0034] The term "receptor mediated activity" refers to any biological activity that results, either directly or indirectly, from binding of a ligand to a receptor.

[0035] The term "agonist" refers to a compound, the presence of which results in a biological activity of a receptor that is the same as the biological activity resulting from the presence of a naturally occurring ligand for the receptor.

[0036] The term "partial agonist" refers to a compound, the presence of which results in a biological activity of a receptor that is of the same type as that resulting from the presence of a naturally occurring ligand for the receptor, but of a lower magnitude.

[0037] The term "antagonist" refers to a compound, the presence of which results in a decrease in the magnitude of a biological activity of a receptor. In certain embodiments, the presence of an antagonist results in complete inhibition of a biological activity of a receptor.

[0038] The term "alkyl" refers to an aliphatic hydrocarbon group. An alkyl may be a "saturated alkyl," which means that it does not contain any alkene or alkyne groups. An alkyl group may be an "unsaturated alkyl," which means that it comprises at least one alkene or alkyne group. An alkyl, whether saturated or unsaturated, may be branched or straight chain. Alkyls may be cyclic or non-cyclic. Cyclic alkyls may include multicyclic systemd including fused alkyl rings. Alkyls may be substituted or unsubstituted. Alkyls include, but are not limited to, methyl, ethyl, propyl, isopropyl, butyl, isobutyl, tertiary butyl, pentyl, hexyl, ethenyl, propenyl, butenyl, cyclopropyl, cyclobutyl, cyclopentyl, cyclohexyl, and the like, each of which may be optionally substituted.

[0039] In certain embodiments, an alkyl comprises 1 to 20 carbon atoms (whenever it appears herein, a numerical range such as "1 to 20" refers to each integer in the given range; e.g., "1 to 20 carbon atoms" means that an alkyl group may comprise only 1 carbon atom, 2 carbon atoms, 3 carbon atoms, etc.. up to and including 20 carbon atoms, although the term "alkyl" also includes instances where no numerical range of carbon atoms is designated).

[0040] The term "lower alkyl" refers to an alkyl comprising 1 to 5 carbon atoms. The term "medium alkyl" refers to an alkyl comprising 5 to 10 carbon atoms. An alkyl may be designated as "Cj-C ₄ alkyl" or similar designations. By way of example only, "C ₁ -C ₄ alkyl" indicates an alkyl having one, two, three, or four carbon atoms, e.g., the alkyl is selected from methyl, ethyl, propyl, iso-propyl, n-butyl, iso-butyl, sec-butyl, t- butyl, ethenyl, propenyl, butenyl, ethynyl, propynyl, and butynyl.

[0041] The term "alkenyl" refers to an alkyl group comprising at least one carbon-carbon double bond.

[0042] The term "alkynyl" refers to an alkyl group comprising at least one carbon-carbon triple bond.

[0049] The term "carbocycle" refers to a group comprising a covalently closed ring, wherein each of the atoms forming the ring is a carbon atom. Carbocylic rings may be formed by three, four, five, six, seven, eight, nine, or more than nine carbon atoms. Carbocycles may be optionally substituted.

[0050] The term "heterocycle" refers to a group comprising a covalently closed ring wherein at least one atom forming the ring is a heteroatom. Heterocyclic rings may be formed by three, four, five, six, seven, eight, nine, or more than nine atoms. Any number of those atoms may be heteroatoms (i.e., a heterocyclic ring may comprise one, two, three, four, five, six, seven, eight, nine, or more than nine heteroatoms). In heterocyclic rings comprising two or more heteroatoms, those two or more heteroatoms may be the same or different from one another. Heterocycles may be optionally substituted. Binding to a heterocycle can be at a heteroatom or via a carbon atom. For example, binding for benzo-fused derivatives, may be via a carbon of the benzenoid ring. Examples of heterocycles include, but are not limited to the following:

wherein D, E, F, and G independently represent a heteroatom. Each of D, E, F, and G may be the same or different from one another.

[0051] The term "heteroatom" refers to an atom other than carbon or hydrogen. Heteroatoms are typically independently selected from oxygen, sulfur, nitrogen, and phosphorus, but are not limited to those atoms. In embodiments in which two or more heteroatoms are present, the two or more heteroatoms may all be the same as one another, or some or all of the two or more heteroatoms may each be different from the others.

[0145] Certain compounds of the present inventions may exist as stereoisomers including optical isomers. The present disclosure is intended to include all stereoisomers and both the racemϊc mixtures of such stereoisomers as well as the individual enantiomers that may be separated according to methods that are known in the art or that may be excluded by synthesis schemes known in the art designed to yield predominantly one enantiomer relative to another. Certain Synthesis Methods

[0146] In certain embodiments, certain compounds of the present invention can by synthesized using the following Schemes. Scheme I

[0147] The process of Scheme I is a multi-step synthetic sequence that commences with the palladium catalyzed cross-coupling of a phenylboronic acid such as structure 2 and an aryl bromide such as structure 1 to form the biaryl structure 3. Deprotection of the methyl ether is followed by nitration and hydrogenation to give the biphenyl amino acid such as structure 4. The amino group is then diazotized under standard conditions and is treated with the appropriate coupling partner to give the final product of structure 6. "R" may be present 0, 1, 2, or 3 times and each R is independently selected from the groups in the "optionally substituted" definition provided above. Scheme II

[0148] The process of Scheme II is a multi-step synthetic sequence that commences with the copper catalyzed cross-coupling of an oxindole such as structure 7 and an aryl or alkyl bromide to provide an jV-substituted oxindole of structure 8. This is then followed by coupling the N-substituted oxindole with the diazonium salt of the biphenyl amino acid such as structure 4 to give the final product of structure 9. "R" may be present 0, 1, 2, or 3 times and each R is independently selected from the groups in the " ^• optionally substituted" definition provided above. Scheme III

X = OEt, or N(CH ₃ ) ₂

[0149] The process of Scheme IH is a multi-step synthetic sequence that commences with the copper catalyzed cross-coupling of an oxindole such as structure 7 and an aryl or alkyl bromide to provide an N-substituted oxindole of structure 8. This is then converted into the structure 10 via reaction with either dimethylformamide dimethylacetal (or equivalent) or triethylorthoformate. This is then reacted with an amine to give the structure 11. ^U R" may be present 0, 1, 2, or 3 times and each R is independently selected from the groups in the "optionally substituted" definition provided above. Scheme IV

[0150] The process of Scheme IV is a single synthetic step which joins the arylated oxindole 8 from Scheme I and an appropriately substituted pyrrolecarboxaldehye

12 in the presence of base to give 13. "R" may be present 0, 1, 2, or 3 times and each R is independently selected from the groups in the "optionally substituted" definition provided above. Scheme V

[0151] The process in Scheme V is a single synthetic step which reaction 14 with phosgene, or some synthetic equivalent, to yield 15. "R" may be present 0, 1, 2, or 3 times and each R is independently selected from the groups in the "optionally substituted" definition provided above.

Scheme VI

R ^x = R ⁶ Or R ⁷

[0152] The process of Scheme VI is a multi-step synthetic sequence that commences with benzothiophene formation from aryl thioether 16. This is then converted into the structure 19 via reaction with diazonium salt 18. Scheme VII

[0153] The process of Scheme VII is a multi-step synthetic sequence that commences with the Wittig olefination of a benzaldehyde such as structure 20 and a phosphonium bromide such as structure 21 to form the olefin 22. Reduction of the nitro group (and/or the olefin) gives the phenyl amine such as structure 23. The amino group is then diazotized under standard conditions and is treated with the appropriate coupling partner to give the final product of structure 24. "R" is selected from the groups in the "optionally substituted" definition provided above. Scheme VIII

,λ- ^<

Q = R ⁶ or -Z-R ⁷ or V = OEt, or N(CH ₃ J ₂ 27 25 MeC(OEt) ₃ 26

[0154] The process of Scheme VIII is a multi-step synthetic sequence that commences with enamine or enol ether formation of an iV-substituted oxindole of structure 25 or its analogs. This is then converted into the structure 27 via reaction with an amine partner. "R" may be present 0, 1 , 2, or 3 times and each R is independently selected from the groups in the "optionally substituted" definition provided above. Scheme IX

X ¹ ' X ² , X ³ = N or CH

[0155] The general process of Scheme IX starts with diazotization of amino compounds 28 under standard condition followed by a coupling reaction with compounds of structure 25 to afford the hydrazone products of structure 29. "R" may be present 0, 1, 2, or 3 times and each R is independently selected from the groups in the "optionally substituted" definition provided above.

[0166] In certain embodiments, a pharmaceutical agent comprising one or more compounds of the present invention is formulated as a depot preparation. Certain such depot preparations are typically longer acting than non-depot preparations. In certain embodiments, such preparations are administered by implantation (for example subcutaneously or intramuscularly) or by intramuscular injection. In certain embodiments, depot preparations are prepared using suitable polymeric or hydrophobic materials (for example an emulsion in an acceptable oil) or ion exchange resins, or as sparingly soluble derivatives, for example, as a sparingly soluble salt.

[0167] In certain embodiments, a pharmaceutical agent comprising one or more compounds of the present invention comprises a delivery system. Examples of

delivery systems include, but are not limited to, liposomes and emulsions. Certain delivery systems are useful for preparing certain pharmaceutical agents including those comprising hydrophobic compounds. In certain embodiments, certain organic solvents such as dimethyl sulfoxide are used.

[0168] In certain embodiments, a pharmaceutical agent comprising one or more compounds of the present invention comprises one or more tissue-specific delivery molecules designed to deliver the pharmaceutical agent to specific tissues or cell types. For example, in certain embodiments, pharmaceutical agents include liposomes coated with a tissue-specific antibody.

[0169] In certain embodiments, a pharmaceutical agent comprising one or more compounds of the present invention comprises a co-solvent system. Certain of such co-solvent systems comprise, for example, benzyl alcohol, a nonpolar surfactant, a water- miscible organic polymer, and an aqueous phase.
