Definitions

  • the disclosure provides compounds as well as their compositions and methods of use.
  • the compounds modulate hematopoietic progenitor kinase 1 (HPK1) activity and are useful in the treatment of various diseases including cancer.
  • HPK1 hematopoietic progenitor kinase 1
  • Hematopoietic progenitor kinase 1 originally cloned from hematopoietic progenitor cells is a member of MAP kinase kinase kinases (MAP4Ks) family, which includes MAP4K1/HPK1, MAP4K2/GCK, MAP4K3/GLK, MAP4K4/HGK, MAP4K5/KHS, and MAP4K6/MINK (Hu, M. C., et al., Genes Dev, 1996. 10(18): p. 2251-64).
  • MAP4Ks MAP kinase kinase kinases
  • HPK1 is of particular interest because it is predominantly expressed in hematopoietic cells such as T cells, B cells, macrophages, dendritic cells, neutrophils, and mast cells (Hu, M. C., et al., Genes Dev, 1996. 10(18): p. 2251-64; Kiefer, F., et al., EMBO J, 1996. 15(24): p. 7013-25).
  • HPK1 kinase activity has been shown to be induced upon activation of T cell receptors (TCR) (Liou, J., et al., Immunity, 2000. 12(4): p.
  • TCR T cell receptors
  • B cell receptors BCR
  • TGF- ⁇ R transforming growth factor receptor
  • EP2 and EP4 G s -coupled PGE 2 receptors
  • HPK1 is important in regulating the functions of various immune cells and it has been implicated in autoimmune diseases and anti-tumor immunity (Shui, J. W., et al., Nat Immunol, 2007. 8(1): p. 84-91; Wang, X., et al., J Biol Chem, 2012. 287(14): p. 11037-48). HPK1 knockout mice were more susceptible to the induction of experimental autoimmune encephalomyelitis (EAE) (Shui, J. W., et al., Nat Immunol, 2007. 8(1): p. 84-91).
  • EAE experimental autoimmune encephalomyelitis
  • HPK1 was downregulated in peripheral blood mononuclear cells of psoriatic arthritis patients or T cells of systemic lupus erythematosus (SLE) patients (Batliwalla, F. M., et al., Mol Med, 2005. 11(1-12): p. 21-9). Those observations suggested that attenuation of HPK1 activity may contribute to autoimmunity in patients. Furthermore, HPK1 may also control anti-tumor immunity via T cell-dependent mechanisms. In the PGE2-producing Lewis lung carcinoma tumor model, the tumors developed more slowly in HPK1 knockout mice as compared to wild-type mice (see US 2007/0087988).
  • HPK1 may be an excellent drug target for enhancing antitumor immunity. Accordingly, there is a need for new compounds that modulate HPK1 activity.

Description

    FIELD OF THE INVENTION
  • The disclosure provides compounds as well as their compositions and methods of use. The compounds modulate hematopoietic progenitor kinase 1 (HPK1) activity and are useful in the treatment of various diseases including cancer.
    • BACKGROUND OF THE INVENTION
  • Hematopoietic progenitor kinase 1 (HPK1) originally cloned from hematopoietic progenitor cells is a member of MAP kinase kinase kinase kinases (MAP4Ks) family, which includes MAP4K1/HPK1, MAP4K2/GCK, MAP4K3/GLK, MAP4K4/HGK, MAP4K5/KHS, and MAP4K6/MINK (Hu, M. C., et al., Genes Dev, 1996. 10(18): p. 2251-64). HPK1 is of particular interest because it is predominantly expressed in hematopoietic cells such as T cells, B cells, macrophages, dendritic cells, neutrophils, and mast cells (Hu, M. C., et al., Genes Dev, 1996. 10(18): p. 2251-64; Kiefer, F., et al., EMBO J, 1996. 15(24): p. 7013-25). HPK1 kinase activity has been shown to be induced upon activation of T cell receptors (TCR) (Liou, J., et al., Immunity, 2000. 12(4): p. 399-408), B cell receptors (BCR) (Liou, J., et al., Immunity, 2000. 12(4): p. 399-408), transforming growth factor receptor (TGF-βR) (Wang, W., et al., J Biol Chem, 1997. 272(36): p. 22771-5; Zhou, G., et al., J Biol Chem, 1999. 274(19): p. 13133-8), or Gs-coupled PGE2 receptors (EP2 and EP4) (Ikegami, R., et al., J Immunol, 2001. 166(7): p. 4689-96). As such, HPK1 regulates diverse functions of various immune cells.
  • HPK1 is important in regulating the functions of various immune cells and it has been implicated in autoimmune diseases and anti-tumor immunity (Shui, J. W., et al., Nat Immunol, 2007. 8(1): p. 84-91; Wang, X., et al., J Biol Chem, 2012. 287(14): p. 11037-48). HPK1 knockout mice were more susceptible to the induction of experimental autoimmune encephalomyelitis (EAE) (Shui, J. W., et al., Nat Immunol, 2007. 8(1): p. 84-91). In human, HPK1 was downregulated in peripheral blood mononuclear cells of psoriatic arthritis patients or T cells of systemic lupus erythematosus (SLE) patients (Batliwalla, F. M., et al., Mol Med, 2005. 11(1-12): p. 21-9). Those observations suggested that attenuation of HPK1 activity may contribute to autoimmunity in patients. Furthermore, HPK1 may also control anti-tumor immunity via T cell-dependent mechanisms. In the PGE2-producing Lewis lung carcinoma tumor model, the tumors developed more slowly in HPK1 knockout mice as compared to wild-type mice (see US 2007/0087988). In addition, it was shown that adoptive transfer of HPK1 deficient T cells was more effective in controlling tumor growth and metastasis than wild-type T cells (Alzabin, S., et al., Cancer Immunol Immunother, 2010. 59(3): p. 419-29). Similarly, BMDCs from HPK1 knockout mice were more efficient to mount a T cell response to eradicate Lewis lung carcinoma as compared to wild-type BMDCs (Alzabin, S., et al., J Immunol, 2009. 182(10): p. 6187-94). These data, in conjunction with the restricted expression of HPK1 in hematopoietic cells and lack of effect on the normal development of immune cells, suggest that HPK1 may be an excellent drug target for enhancing antitumor immunity. Accordingly, there is a need for new compounds that modulate HPK1 activity.

  • It is further appreciated that certain features of the invention, which are, for clarity, described in the context of separate embodiments, can also be provided in combination in a single embodiment (while the embodiments are intended to be combined as if written in multiply dependent form). Conversely, various features of the invention which are, for brevity, described in the context of a single embodiment, can also be provided separately or in any suitable subcombination. Thus, it is contemplated as features described as embodiments of the compounds of Formula (I) can be combined in any suitable combination.
  • At various places in the present specification, certain features of the compounds are disclosed in groups or in ranges. It is specifically intended that such a disclosure include each and every individual subcombination of the members of such groups and ranges. For example, the term “C1-6 alkyl” is specifically intended to individually disclose (without limitation) methyl, ethyl, C3 alkyl, C4 alkyl, C5 alkyl and C6 alkyl.
  • The term “n-membered,” where n is an integer, typically describes the number of ring-forming atoms in a moiety where the number of ring-forming atoms is n. For example, piperidinyl is an example of a 6-membered heterocycloalkyl ring, pyrazolyl is an example of a 5-membered heteroaryl ring, pyridyl is an example of a 6-membered heteroaryl ring and 1,2,3,4-tetrahydro-naphthalene is an example of a 10-membered cycloalkyl group.
  • At various places in the present specification, variables defining divalent linking groups may be described. It is specifically intended that each linking substituent include both the forward and backward forms of the linking substituent. For example, —NR(CR′R″)n— includes both —NR(CR′R″)n— and —(CR′R″)nNR— and is intended to disclose each of the forms individually. Where the structure requires a linking group, the Markush variables listed for that group are understood to be linking groups. For example, if the structure requires a linking group and the Markush group definition for that variable lists “alkyl” or “aryl” then it is understood that the “alkyl” or “aryl” represents a linking alkylene group or arylene group, respectively.
  • The term “substituted” means that an atom or group of atoms formally replaces hydrogen as a “substituent” attached to another group. The term “substituted”, unless otherwise indicated, refers to any level of substitution, e.g., mono-, di-, tri-, tetra- or penta-substitution, where such substitution is permitted. The substituents are independently selected, and substitution may be at any chemically accessible position. It is to be understood that substitution at a given atom is limited by valency. It is to be understood that substitution at a given atom results in a chemically stable molecule. The phrase “optionally substituted” means unsubstituted or substituted. The term “substituted” means that a hydrogen atom is removed and replaced by a substituent. A single divalent substituent, e.g., oxo, can replace two hydrogen atoms.
  • The term “Cn-m” indicates a range which includes the endpoints, wherein n and m are integers and indicate the number of carbons. Examples include C1-4, C1-6 and the like.
  • The term “alkyl,” employed alone or in combination with other terms, refers to a saturated hydrocarbon group that may be straight-chained or branched. The term “Cn-m alkyl”, refers to an alkyl group having n to m carbon atoms. An alkyl group formally corresponds to an alkane with one C—H bond replaced by the point of attachment of the alkyl group to the remainder of the compound. In some embodiments, the alkyl group contains from 1 to 6 carbon atoms, from 1 to 4 carbon atoms, from 1 to 3 carbon atoms, or 1 to 2 carbon atoms. Examples of alkyl moieties include, but are not limited to, chemical groups such as methyl, ethyl, n-propyl, isopropyl, n-butyl, tert-butyl, isobutyl, sec-butyl; higher homologs such as 2-methyl-1-butyl, n-pentyl, 3-pentyl, n-hexyl, 1,2,2-trimethylpropyl and the like.

  • Compounds of formula (Ia) (compounds of Formula I wherein R1 is C(O)NRcRd) can be prepared, using a process as illustrated in Scheme 1. In the process depicted in Scheme 1, compounds of formula 1-2 is formed after protection of the NH group of the compounds of formula 1-1 with a suitable protecting group (e.g. SEM or Boc). The chloro substituent in the compounds of formula 1-2 can be converted into CyA via a number of different cross-coupling reactions, including Suzuki (e.g., in the presence of a palladium catalyst, such as Xphos Pd G2, and a base, such as potassium phosphate) or Stille (e.g., in the presence of a palladium(0) catalyst, such as tetrakis(triphenylphosphine)palladium(0)), and others, to give the compounds of formula 1-3. Deprotection of the protecting group (e.g., under acidic conditions, such as treatment with HCl or TFA) results in the formation of compounds of formula 1-4.

    • HPK1 Kinase
  • Extensive studies have established that HPK1 is a negative regulator of T cell and B cell activation (Hu, M. C., et al., Genes Dev, 1996. 10(18): p. 2251-64; Kiefer, F., et al., EMBO J, 1996. 15(24): p. 7013-25). HPK1-deficient mouse T cells showed dramatically increased activation of TCR proximal signaling, enhanced IL-2 production, and hyper-proliferation in vitro upon anti-CD3 stimulation (Shui, J. W., et al., Nat Immunol, 2007. 8(1): p. 84-91). Similar to T cells, HPK1 knockout B cells produced much higher levels of IgM and IgG isoforms after KLH immunization and displayed hyper-proliferation potentially as a result of enhanced BCR signaling. Wang, X., et al., J Biol Chem, 2012. 287(14): p. 11037-48. Mechanistically, during TCR or BCR signaling, HPK1 is activated by LCK/ZAP70 (T cells) or SYK/LYN (B cells) mediated-Tyr379 phosphorylation and its subsequent binding to adaptor protein SLP-76 (T cells) or BLNK (B cells) (Wang, X., et al., J Biol Chem, 2012. 287(14): p. 11037-48). Activated HPK1 phosphorylates SLP-76 on Ser376 or BLNK on Thr152, leading to the recruitment of signaling molecule 14-3-3 and ultimate ubiquitination-mediated degradation of SLP-76 or BLNK (Liou, J., et al., Immunity, 2000. 12(4): p. 399-408; Di Bartolo, V., et al., J Exp Med, 2007. 204(3): p. 681-91). As SLP-76 and BLNK are essential for TCR/BCR-mediated signaling activation (e.g. ERK, phospholipase Cyl, calcium flux, and NFAT activation), HPK1-mediated downregulation of these adaptor proteins provide a negative feedback mechanism to attenuate signaling intensity during T cell or B cell activation (Wang, X., et al., J Biol Chem, 2012. 287(14): p. 11037-48).
  • The bone marrow-derived dendritic cells (BDMCs) from HPK1 knockout mice showed higher expression of co-stimulatory molecules (e.g. CD80/CD86) and enhanced production of proinflammatory cytokines (IL-12, TNF-α etc), and demonstrated superior ability to stimulate T cell proliferation in vitro and in vivo as compared to wild-type DCs (Alzabin, S., et al., J Immunol, 2009. 182(10): p. 6187-94). These data suggest that HPK1 is also an important negative regulator of dendritic cell activation (Alzabin, S., et al., J Immunol, 2009. 182(10): p. 6187-94). However, the signaling mechanisms underlying HPK-1 mediated negative regulation of DC activation remains to be elucidated.
  • In contrast, HPK1 appears to be a positive regulator of suppressive functions of regulatory T cells (Treg) (Sawasdikosol, S. et al., The journal of immunology, 2012. 188 (supplement 1): p. 163). HPK1 deficient mouse Foxp3+ Tregs were defective in suppressing TCR-induced effector T cell proliferation, and paradoxically gained the ability to produce IL-2 following TCR engagement (Sawasdikosol, S. et al., The Journal of Immunology, 2012. 188 (supplement 1): p. 163). These data suggest that HPK1 is an important regulator of Treg functions and peripheral self-tolerance.
  • HPK1 was also involved in PGE2-mediated inhibition of CD4+ T cell activation (Ikegami, R., et al., J Immunol, 2001. 166(7): p. 4689-96). Studies published in US 2007/0087988 indicated that HPK1 kinase activity was increased by exposure to physiological concentrations of PGE2 in CD4+ T cells and this effect was mediated by PEG2-induced PKA activation. The proliferation of HPK1 deficient T cells was resistant to the suppressive effects of PGE2 (see US 2007/0087988). Therefore, PGE2-mediated activation of HPK1 may represent a novel regulatory pathway of modulating immune response.

In some embodiments, the hydroxypropyl methylcellulose is hydroxypropyl methylcellulose 2208 K4M (e.g., Methocel K4 M Premier™) and/or hydroxypropyl methylcellulose 2208 K100LV (e.g., Methocel KOOLV™).
  • In some embodiments, the polyethylene oxide is polyethylene oxide WSR 1105 (e.g., Polyox WSR 1105™).
  • In some embodiments, a wet granulation process is used to produce the composition. In some embodiments, a dry granulation process is used to produce the composition.
  • The compositions can be formulated in a unit dosage form, each dosage containing from about 5 to about 1,000 mg (1 g), more usually about 100 mg to about 500 mg, of the active ingredient. In some embodiments, each dosage contains about 10 mg of the active ingredient. In some embodiments, each dosage contains about 50 mg of the active ingredient. In some embodiments, each dosage contains about 25 mg of the active ingredient. The term “unit dosage forms” refers to physically discrete units suitable as unitary dosages for human subjects and other mammals, each unit containing a predetermined quantity of active material calculated to produce the desired therapeutic effect, in association with a suitable pharmaceutical excipient.
  • The components used to formulate the pharmaceutical compositions are of high purity and are substantially free of potentially harmful contaminants (e.g., at least National Food grade, generally at least analytical grade, and more typically at least pharmaceutical grade). Particularly for human consumption, the composition is preferably manufactured or formulated under Good Manufacturing Practice standards as defined in the applicable regulations of the U.S. Food and Drug Administration. For example, suitable formulations may be sterile and/or substantially isotonic and/or in full compliance with all Good Manufacturing Practice regulations of the U.S. Food and Drug Administration.
  • The active compound may be effective over a wide dosage range and is generally administered in a therapeutically effective amount. It will be understood, however, that the amount of the compound actually administered will usually be determined by a physician, according to the relevant circumstances, including the condition to be treated, the chosen route of administration, the actual compound administered, the age, weight, and response of the individual patient, the severity of the patient's symptoms and the like.
  • The therapeutic dosage of a compound of the present invention can vary according to, e.g., the particular use for which the treatment is made, the manner of administration of the compound, the health and condition of the patient, and the judgment of the prescribing physician. The proportion or concentration of a compound of the invention in a pharmaceutical composition can vary depending upon a number of factors including dosage, chemical characteristics (e.g., hydrophobicity), and the route of administration. For example, the compounds of the invention can be provided in an aqueous physiological buffer solution containing about 0.1 to about 10% w/v of the compound for parenteral administration. Some typical dose ranges are from about 1 μg/kg to about 1 g/kg of body weight per day. In some embodiments, the dose range is from about 0.01 mg/kg to about 100 mg/kg of body weight per day. The dosage is likely to depend on such variables as the type and extent of progression of the disease or disorder, the overall health status of the particular patient, the relative biological efficacy of the compound selected, formulation of the excipient, and its route of administration. Effective doses can be extrapolated from dose-response curves derived from in vitro or animal model test systems.
  • For preparing solid compositions such as tablets, the principal active ingredient is mixed with a pharmaceutical excipient to form a solid preformulation composition containing a homogeneous mixture of a compound of the present invention. When referring to these preformulation compositions as homogeneous, the active ingredient is typically dispersed evenly throughout the composition so that the composition can be readily subdivided into equally effective unit dosage forms such as tablets, pills and capsules. This solid preformulation is then subdivided into unit dosage forms of the type described above containing from, e.g., about 0.1 to about 1000 mg of the active ingredient of the present invention.
  • The tablets or pills of the present invention can be coated or otherwise compounded to provide a dosage form affording the advantage of prolonged action. For example, the tablet or pill can comprise an inner dosage and an outer dosage component, the latter being in the form of an envelope over the former. The two components can be separated by an enteric layer which serves to resist disintegration in the stomach and permit the inner component to pass intact into the duodenum or to be delayed in release. A variety of materials can be used for such enteric layers or coatings, such materials including a number of polymeric acids and mixtures of polymeric acids with such materials as shellac, cetyl alcohol and cellulose acetate.
  • The liquid forms in which the compounds and compositions of the present invention can be incorporated for administration orally or by injection include aqueous solutions, suitably flavored syrups, aqueous or oil suspensions, and flavored emulsions with edible oils such as cottonseed oil, sesame oil, coconut oil, or peanut oil, as well as elixirs and similar pharmaceutical vehicles.
  • Compositions for inhalation or insufflation include solutions and suspensions in pharmaceutically acceptable, aqueous or organic solvents, or mixtures thereof, and powders.
  • The liquid or solid compositions may contain suitable pharmaceutically acceptable excipients as described supra. In some embodiments, the compositions are administered by the oral or nasal respiratory route for local or systemic effect. Compositions can be nebulized by use of inert gases. Nebulized solutions may be breathed directly from the nebulizing device or the nebulizing device can be attached to a face mask, tent, or intermittent positive pressure breathing machine. Solution, suspension, or powder compositions can be administered orally or nasally from devices which deliver the formulation in an appropriate manner.
  • Topical formulations can contain one or more conventional carriers. In some embodiments, ointments can contain water and one or more hydrophobic carriers selected from, e.g., liquid paraffin, polyoxyethylene alkyl ether, propylene glycol, white Vaseline, and the like. Carrier compositions of creams can be based on water in combination with glycerol and one or more other components, e.g., glycerinemonostearate, PEG-glycerinemonostearate and cetylstearyl alcohol. Gels can be formulated using isopropyl alcohol and water, suitably in combination with other components such as, e.g., glycerol, hydroxyethyl cellulose, and the like. In some embodiments, topical formulations contain at least about 0.1, at least about 0.25, at least about 0.5, at least about 1, at least about 2 or at least about 5 wt % of the compound of the invention. The topical formulations can be suitably packaged in tubes of, e.g., 100 g which are optionally associated with instructions for the treatment of the select indication, e.g., psoriasis or other skin condition.
  • The amount of compound or composition administered to a patient will vary depending upon what is being administered, the purpose of the administration, such as prophylaxis or therapy, the state of the patient, the manner of administration and the like. In therapeutic applications, compositions can be administered to a patient already suffering from a disease in an amount sufficient to cure or at least partially arrest the symptoms of the disease and its complications. Effective doses will depend on the disease condition being treated as well as by the judgment of the attending clinician depending upon factors such as the severity of the disease, the age, weight and general condition of the patient and the like.
  • The compositions administered to a patient can be in the form of pharmaceutical compositions described above. These compositions can be sterilized by conventional sterilization techniques, or may be sterile filtered. Aqueous solutions can be packaged for use as is, or lyophilized, the lyophilized preparation being combined with a sterile aqueous carrier prior to administration. The pH of the compound preparations typically will be between 3 and 11, more preferably from 5 to 9 and most preferably from 7 to 8. It will be understood that use of certain of the foregoing excipients, carriers or stabilizers will result in the formation of pharmaceutical salts.
  • The therapeutic dosage of a compound of the present invention can vary according to, e.g., the particular use for which the treatment is made, the manner of administration of the compound, the health and condition of the patient, and the judgment of the prescribing physician. The proportion or concentration of a compound of the invention in a pharmaceutical composition can vary depending upon a number of factors including dosage, chemical characteristics (e.g., hydrophobicity), and the route of administration. For example, the compounds of the invention can be provided in an aqueous physiological buffer solution containing about 0.1 to about 10% w/v of the compound for parenteral administration.

Effective doses can be extrapolated from dose-response curves derived from in vitro or animal model test systems.
    • Labeled Compounds and Assay Methods
  • The compounds of the present disclosure can further be useful in investigations of biological processes in normal and abnormal tissues. Thus, another aspect of the present invention relates to labeled compounds of the invention (radio-labeled, fluorescent-labeled, etc.) that would be useful not only in imaging techniques but also in assays, both in vitro and in vivo, for localizing and quantitating HPK1 protein in tissue samples, including human. Accordingly, the present invention includes HPK1 binding assays that contain such labeled compounds.
  • The present invention further includes isotopically-substituted compounds of the disclosure. An “isotopically-substituted” compound is a compound of the invention where one or more atoms are replaced or substituted by an atom having an atomic mass or mass number different from the atomic mass or mass number typically found in nature (i.e., naturally occurring). It is to be understood that a “radio-labeled” compound is a compound that has incorporated at least one isotope that is radioactive (e.g., radionuclide). Suitable radionuclides that may be incorporated in compounds of the present invention include but are not limited to 3H (also written as T for tritium), 11C, 13C, 14C, 13N, 15N, 15O, 17O, 18O, 18F, 35S, 36Cl, 82Br, 75Br, 76Br, 77Br, 123I, 124I, 125I and 131I. The radionuclide that is incorporated in the instant radio-labeled compounds will depend on the specific application of that radio-labeled compound. In some embodiments the radionuclide is selected from the group consisting of 3H, 14C, 125I, 35S and 82Br. Synthetic methods for incorporating radio-isotopes into organic compounds are known in the art.
  • Specifically, a labeled compound of the invention can be used in a screening assay to identify and/or evaluate compounds. For example, a newly synthesized or identified compound (i.e., test compound) which is labeled can be evaluated for its ability to bind a HPK1 protein by monitoring its concentration variation when contacting with the HPK1, through tracking of the labeling. For example, a test compound (labeled) can be evaluated for its ability to reduce binding of another compound which is known to bind to a HPK1 protein (i.e., standard compound). Accordingly, the ability of a test compound to compete with the standard compound for binding to the HPK1 protein directly correlates to its binding affinity. Conversely, in some other screening assays, the standard compound is labeled and test compounds are unlabeled. Accordingly, the concentration of the labeled standard compound is monitored in order to evaluate the competition between the standard compound and the test compound, and the relative binding affinity of the test compound is thus ascertained.
    • Kits
  • The present disclosure also includes pharmaceutical kits useful, e.g., in the treatment or prevention of diseases or disorders associated with the activity of HPK1, such as cancer or infections, which include one or more containers containing a pharmaceutical composition comprising a therapeutically effective amount of a compound of Formula (I), or any of the embodiments thereof. Such kits can further include one or more of various conventional pharmaceutical kit components, such as, e.g., containers with one or more pharmaceutically acceptable carriers, additional containers, etc., as will be readily apparent to those skilled in the art. Instructions, either as inserts or as labels, indicating quantities of the components to be administered, guidelines for administration, and/or guidelines for mixing the components, can also be included in the kit.
  • The invention will be described in greater detail by way of specific examples. The following examples are offered for illustrative purposes, and are not intended to limit the invention in any manner. Those of skill in the art will readily recognize a variety of non-critical parameters which can be changed or modified to yield essentially the same results. The compounds of the Examples have been found to inhibit the activity of HPK1 according to at least one assay described herein.
