Definitions

  • the present invention relates to a FoxM1 gene splicing modifier selected from a compound of formula (I) or of formula (VI)
  • a and B are as defined herein, or a pharmaceutically acceptable salt thereof, for use in the treatment, prevention and/or delay of progression of cancer.
  • FoxM1 is a transcription factor of the Forkhead family. It is also known in the literature as Trident (in mouse), HFH-11 (in human), WIN or INS-1 (in rat), MPP-2 (partial human cDNA) or FKHL-16.
  • the Forkhead family comprises a large number of transcription factors defined by a conserved DNA binding domain called Forkhead or winged-helix domain.
  • the FoxM1 gene was cloned by screening cDNA libraries with degenerate primers for homologues with a conserved Forkhead DNAbinding domain (W. Korver, J. Roose, H. Clevers, Nucleic Acids Res. 25 (1997) 1715-1719).
  • the FoxM1 gene was revealed to encode a Forkhead transcription factor family member that exhibits 45% identity in the DNA-binding domain with five of its closest related Forkhead members, namely FoxA3 (HNF-3 ⁇ , FoxC1 (fkh-1), FoxF2 (FREAC-2), FoxK1 (ILF) and FoxN2 (HTLF).
  • FoxA3 HNF-3 ⁇
  • FoxC1 fkh-1
  • FoxF2 FREAC-2
  • FoxK1 IGF
  • HTLF FoxN2
  • MPP-2 stands for MPM-2-reactive phosphoprotein-2 and was identified after screening a lymphoblast-derived cDNA library with the MPM-2 monoclonal antibody, which binds specifically to epitopes on mitotic proteins that are phosphorylated in a phosphoserine-proline dependent manner.
  • FoxM1 binds DNA in vitro through the consensus site TAAACA. This motif shares the core sequence recognized by other members of the forkhead family. In particular, repeats of these motifs, in alternating orientation, were often characterized within the selected binding sequences for FoxM1.
  • the human FoxM1 gene is a 10-exon structure spanning approximately 25 kb on the 12p13-3 chromosomal band (telomeric position) (W. Korver, J. Roose, H. Clevers, Nucleic Acids Res. 25 (1997) 1715-1719).
  • Two exons, named exons Va and VIIa, also referred to as exon A1 (or rat exon 6) and A2 respectively, are alternatively spliced (H. Ye, T. F. Kelly, U. Samadani, L. Lim, S. Rubio, D. G. Overdier, K. A. Roebuck, R. H. Costa, Mol. Cell Biol. 17 (1997) 1626-1641).
  • Exon Va encodes a 15 amino-acidinsertion within the C-terminal part of the DNA binding-domain, and is not seen in any of the other Forkhead transcription factor family members.
  • Exon VIIa represents a 38 amino-acid insertion within the C-terminus of the protein.
  • Differential splicing of exons Va and VIIa in human FoxM1 gives rise to three classes of transcripts, class A containing both alternative exons, class B containing none of the alternative exons, and class C in which exon Va only is retained (H. Ye, T. F. Kelly, U. Samadani, L. Lim, S. Rubio, D. G. Overdier, K. A. Roebuck, R. H. Costa, Mol. Cell Biol.
  • FoxM1B and FoxM1C are transcriptionally active, whereas FoxM1A is transcriptionally inactive, due to the insertion of exon VIIa in the C-terminal transactivation domain.
  • This disruption of the transactivation domain in FoxM1A not only leads to transcriptional inactivation, it might also cause this variant to act as a dominant-negative variant as it has retained normal DNA binding activity in the absence of a functional transactivation domain (H. Ye, T. F. Kelly, U. Samadani, L. Lim, S. Rubio, D. G. Overdier, K. A. Roebuck, R. H. Costa, Mol. Cell Biol. 17 (1997) 1626-1641).
  • FoxM1 is overexpressed in a broad range of tumor types, including those of neural, gastrointestinal, and reproductive origin (see Bektas et al., supra; Nakamura et al., 2004, Oncogene 23: 2385-400; Pilarsky et al., 2004, Neoplasia. Q: 744-50; Liu et al., 2006, Cancer Res 66: 3593-602).
  • This expression pattern of FoxM1 is attributed to the ability of FoxM1 to transactivate genes required for cell cycle progression (Wang et al., 2002, Proc Nat. Acad Sci US A 99:16881-6).
  • EP 2 298 896 (A1) discloses siRNA molecules inhibiting expression of FoxM1B protein and the use of the siRNA molecules for inhibiting tumor growth.
  • WO 2011/127297 discloses a composition comprising a siRNA FoxM1 inhibitor and Herceptin for the treatment of breast cancer.
  • WO 2014/028459 discloses 1,4-disubstituted pyridazine analogs and methods for treating SMN-deficiency related conditions.
  • WO 2014/116845 discloses thiadiazole analogs and methods for treating SMN-deficiency related conditions.
  • WO 2015/017589 discloses 1,4-disubstituted pyridazine analogs and methods for treating SMN-deficiency related conditions.
  • the problem to be solved by the present invention was to provide new compounds suitable for modifying splicing of the FoxM1 gene for use in the treatment of cancer.

Human fibroblasts were incubated with compounds of present invention at different concentrations for 24 hours, and changes in FoxM1_FL (containing exon VIIa) and FoxM1_ ⁇ VIIa (lacking exon VIIa) mRNA expression were assessed by RT-qPCR.

  • heterocycloalkylaryl haloalkylheteroaryl
  • arylalkylheterocycloalkyl or “alkoxyalkyl”.
  • the last member of the combination is the radical which is binding to the rest of the molecule.
  • the other members of the combination are attached to the binding radical in reversed order in respect of the literal sequence, e.g. the combination arylalkylheterocycloalkyl refers to a heterocycloalkyl-radical which is substituted by an alkyl which is substituted by an aryl.
  • the term “one or more” refers to the range from one substituent to the highest possible number of substitution, i.e. replacement of one hydrogen up to replacement of all hydrogens by substituents.
  • substituted denotes an atom or a group of atoms replacing a hydrogen atom on the parent molecule.
  • substituted denotes that a specified group bears one or more substituents. Where any group can carry multiple substituents and a variety of possible substituents is provided, the substituents are independently selected and need not to be the same.
  • unsubstituted means that the specified group bears no substituents.
  • optionally substituted means that the specified group is unsubstituted or substituted by one or more substituents, independently chosen from the group of possible substituents.

    • BACKGROUND
  • FoxM1 is a transcription factor of the Forkhead family. It is also known in the literature as Trident (in mouse), HFH-11 (in human), WIN or INS-1 (in rat), MPP-2 (partial human cDNA) or FKHL-16. The Forkhead family comprises a large number of transcription factors defined by a conserved DNA binding domain called Forkhead or winged-helix domain. The FoxM1 gene was cloned by screening cDNA libraries with degenerate primers for homologues with a conserved Forkhead DNAbinding domain (W. Korver, J. Roose, H. Clevers, Nucleic Acids Res. 25 (1997) 1715-1719). The FoxM1 gene was revealed to encode a Forkhead transcription factor family member that exhibits 45% identity in the DNA-binding domain with five of its closest related Forkhead members, namely FoxA3 (HNF-3γ, FoxC1 (fkh-1), FoxF2 (FREAC-2), FoxK1 (ILF) and FoxN2 (HTLF). The FoxM1 C-terminal region was found to have homology (76% identity) with a human partial cDNA encoding an open reading-frame of 221 amino acids, termed MPP-2. MPP-2 stands for MPM-2-reactive phosphoprotein-2 and was identified after screening a lymphoblast-derived cDNA library with the MPM-2 monoclonal antibody, which binds specifically to epitopes on mitotic proteins that are phosphorylated in a phosphoserine-proline dependent manner. FoxM1 binds DNA in vitro through the consensus site TAAACA. This motif shares the core sequence recognized by other members of the forkhead family. In particular, repeats of these motifs, in alternating orientation, were often characterized within the selected binding sequences for FoxM1.
  • The human FoxM1 gene is a 10-exon structure spanning approximately 25 kb on the 12p13-3 chromosomal band (telomeric position) (W. Korver, J. Roose, H. Clevers, Nucleic Acids Res. 25 (1997) 1715-1719). Two exons, named exons Va and VIIa, also referred to as exon A1 (or rat exon 6) and A2 respectively, are alternatively spliced (H. Ye, T. F. Kelly, U. Samadani, L. Lim, S. Rubio, D. G. Overdier, K. A. Roebuck, R. H. Costa, Mol. Cell Biol. 17 (1997) 1626-1641). Exon Va encodes a 15 amino-acidinsertion within the C-terminal part of the DNA binding-domain, and is not seen in any of the other Forkhead transcription factor family members. Exon VIIa represents a 38 amino-acid insertion within the C-terminus of the protein. Differential splicing of exons Va and VIIa in human FoxM1, gives rise to three classes of transcripts, class A containing both alternative exons, class B containing none of the alternative exons, and class C in which exon Va only is retained (H. Ye, T. F. Kelly, U. Samadani, L. Lim, S. Rubio, D. G. Overdier, K. A. Roebuck, R. H. Costa, Mol. Cell Biol. 17 (1997) 1626-1641). Both FoxM1B and FoxM1C are transcriptionally active, whereas FoxM1A is transcriptionally inactive, due to the insertion of exon VIIa in the C-terminal transactivation domain. This disruption of the transactivation domain in FoxM1A not only leads to transcriptional inactivation, it might also cause this variant to act as a dominant-negative variant as it has retained normal DNA binding activity in the absence of a functional transactivation domain (H. Ye, T. F. Kelly, U. Samadani, L. Lim, S. Rubio, D. G. Overdier, K. A. Roebuck, R. H. Costa, Mol. Cell Biol. 17 (1997) 1626-1641).
  • FoxM1 is overexpressed in a broad range of tumor types, including those of neural, gastrointestinal, and reproductive origin (see Bektas et al., supra; Nakamura et al., 2004, Oncogene 23: 2385-400; Pilarsky et al., 2004, Neoplasia. Q: 744-50; Liu et al., 2006, Cancer Res 66: 3593-602). This expression pattern of FoxM1 is attributed to the ability of FoxM1 to transactivate genes required for cell cycle progression (Wang et al., 2002, Proc Nat. Acad Sci US A 99:16881-6). Increased nuclear staining of FoxM1B found in human basal cell carcinomas suggests that FoxM1 is required for cellular proliferation in human cancers (Teh et al., 2002, Cancer Res. 62: 4773-80). The detailed role of FoxM1 in establishing or facilitating tumor progression and disease management has not been fully elucidated, however.

    • Pharmaceutical Compositions, Administration and Uses
  • Another embodiment provides pharmaceutical compositions or medicaments containing the compounds of the invention and a therapeutically inert carrier, diluent or excipient, as well as methods of using the compounds of the invention to prepare such compositions and medicaments. In one example, compounds of formula I may be formulated by mixing at ambient temperature at the appropriate pH, and at the desired degree of purity, with physiologically acceptable carriers, i.e., carriers that are non-toxic to recipients at the dosages and concentrations employed into a galenical administration form. The pH of the formulation depends mainly on the particular use and the concentration of compound, but preferably ranges anywhere from about 3 to about 8. In one example, a compound of formula I is formulated in an acetate buffer, at pH 5. In another embodiment, the compounds of formula I are sterile. The compound may be stored, for example, as a solid or amorphous composition, as a lyophilized composition or as an aqueous solution.
  • Compositions are formulated, dosed, and administered in a fashion consistent with good medical practice. Factors for consideration in this context include the particular disorder being treated, the particular mammal being treated, the clinical condition of the individual patient, the cause of the disorder, the site of delivery of the agent, the method of administration, the scheduling of administration, and other factors known to medical practitioners. The “effective amount” of the compound to be administered will be governed by such considerations, and is the minimum amount necessary to modify FoxM1 gene splicing. For example, such amount may be below the amount that is toxic to normal cells, or the mammal as a whole.
  • The compounds of the invention may be administered by any suitable means, including oral, topical(including buccal and sublingual), rectal, vaginal, transdermal, parenteral, subcutaneous, intraperitoneal, intrapulmonary, intradermal, intrathecal and epidural and intranasal, and, if desired for local treatment, intralesional administration. Parenteral infusions include intramuscular, intravenous, intraarterial, intraperitoneal, or subcutaneous administration.
  • The compounds of the present invention may be administered in any convenient administrative form, e.g., tablets, powders, capsules, solutions, dispersions, suspensions, syrups, sprays, suppositories, gels, emulsions, patches, etc. Such compositions may contain components conventional in pharmaceutical preparations, e.g., diluents, carriers, pH modifiers, sweeteners, bulking agents, and further active agents.
  • A typical composition is prepared by mixing a compound of the present invention and a carrier or excipient. Suitable carriers and excipients are well known to those skilled in the art and are described in detail in, e.g., Ansel, Howard C., et al., Ansel's Pharmaceutical Dosage Forms and Drug Delivery Systems. Philadelphia: Lippincott, Williams & Wilkins, 2004; Gennaro, Alfonso R., et al. Remington: The Science and Practice of Pharmacy. Philadelphia: Lippincott, Williams & Wilkins, 2000; and Rowe, Raymond C. Handbook of Pharmaceutical Excipients. Chicago, Pharmaceutical Press, 2005. The compositions may also include one or more buffers, stabilizing agents, surfactants, wetting agents, lubricating agents, emulsifiers, suspending agents, preservatives, antioxidants, opaquing agents, glidants, processing aids, colorants, sweeteners, perfuming agents, flavoring agents, diluents and other known additives to provide an elegant presentation of the drug (i.e., a compound of the present invention or pharmaceutical composition thereof) or aidin the manufacturing of the pharmaceutical product (i.e., medicament).
  • An example of a suitable oral dosage form is a tablet containing about 25 mg, 50 mg, 100 mg, 250 mg, or 500 mg of the compound of the invention compounded with about 90-30 mg anhydrous lactose, about 5-40 mg sodium croscarmellose, about 5-30 mg polyvinylpyrrolidone (PVP) K30, and about 1-10 mg magnesium stearate. The powdered ingredients are first mixed together and then mixed with a solution of the PVP. The resulting composition can be dried, granulated, mixed with the magnesium stearate and compressed to tablet form using conventional equipment. An example of an aerosol composition can be prepared by dissolving the compound, for example 5-400 mg, of the invention in a suitable buffer solution, e.g. a phosphate buffer, adding a tonicifier, e.g. a salt such sodium chloride, if desired. The solution may be filtered, e.g., using a 0.2 micron filter, to remove impurities and contaminants.

    • Example 1 Monitoring Expression Levels of FoxM1 Splice Variants Using Real-Time Quantitative PCR
  • Human fibroblasts were plated at 10,000 cells/well in 200 μl DMEM with GlutaMAX and 10% FBS in 96-well plates in a cell culture incubator (37° C., 5% CO2, 100% relative humidity). Cells were then treated with compounds at different concentrations (0.1-300 nM, each in 0.5% DMSO) in triplicate for 24 hours. RNA extraction was performed as per instructions mentioned in the Ambion® Cells-to-CT™ Kits from Applied Biosystems®. RNA samples were frozen at −20° C. until further analysis. Relative expression levels of full-length FoxM1 (FoxM1_FL) or FoxM1 lacking exon VIIa (FoxM1_ΔVIIa) with GAPDH for internal control, was measured using one-step multiplex reverse transcription-polymerase chain reaction (RT-PCR). TaqMan® FAM probes were used for relative quantitation of FoxM1_FL or FoxM1_ΔVIIa expression levels and TaqMan® VIC probes were used for relative quantitation of human GAPDH levels. The fidelity of the amplification methods was determined using the AACt relative quantification method for quantitative PCR.
  • Compounds Induce Alternative Splicing of FoxM1 Towards Full-Length FoxM1
  • To investigate an effect on splicing of FoxM1, human fibroblasts were treated for 24 hours with compounds of the present invention in dose response, and analysed by RT-qPCR for presence of mRNA including (FoxM1_FL) or excluding the exon VIIa (FoxM1_ΔVIIa). FIG. 1A, FIG. 1B, FIG. 1C, FIG. 1D, FIG. 1E, FIG. 1F, FIG. 1G, FIG. 1H and FIG. 11I show that all compounds increased expression of the FoxM1_FL mRNA. Correspondingly, the mRNAs for FoxM1_ΔVIIa declined. The data demonstrate that upregulation of FoxM1_FL with downregulation of FoxM1_ΔVIIa by treatment with compounds of present invention are directly correlated, indicating an effect of the compounds on alternative splicing of FoxM1. The resulting concentration dependence curves of the FoxM1_ΔVIIa splice variant were fitted to a Hill binding equation to yield IC50 values that are described in Table 1. The data demonstrate that all compounds affect FoxM1 splicing with various potencies, ranging from IC50 values from 0.7 to 345 nM. Taken together, the data underline a splicing modifying activity in the FoxM1 gene.
  • This may result in arrest of cell cycle and induction of apoptosis, as the FoxM1_FL variant created by compound treatment is functionally inactive, and therefore will antagonize the pro-proliferating effect of functional FoxM1 (H. Ye, T. F. Kelly, U. Samadani, L. Lim, S. Rubio, D. G. Overdier, K. A. Roebuck, R. H. Costa, Mol. Cell Biol. 17 (1997) 1626-1641).

    • Example 2 Monitoring Expression Levels of SMN Splice Variants Using Real-Time Quantitative PCR
  • Spinal muscular atrophy (SMA) is a neuromuscular disorder due to mutations in the Survival of Motor Neuron (SMN) gene. Loss of SMN is deleterious to motor neurons and results in neuromuscular insufficiency, a hallmark of the disease. From a genetic point of view, SMA is an autosomal recessive condition, caused by disruption of SMN1 gene, located in 5q13 (Lefebvre S. et al. (1995) Cell 80: 155-165). More than 98% of patients with spinal muscular atrophy have a homozygous disruption of SMN1 by deletion, rearrangement, or mutation. All these patients, however, retain at least one copy of the related SMN2 gene.
  • Compounds of present invention have been described in WO 2014/028459 (A1), WO 2014/116845 (A1) and in WO 2015/017589 (A1) as being effective splicing modifiers of the SMN2 gene and thus suitable for upregulation of SMN protein and thus for the treatment of SMA.
  • The potency of the compounds of present invention regarding SMN2 splicing modulation as assessed by the half-maximal effects (EC50) of SMN protein is evident from Activity Table on pages 189 to 192 of WO2014028459A1 and from Activity Table on pages 124 to 141 of WO2014116845A1.
  • The method of cellular SMN ELISA to measure the effects of compounds on SMN protein elevation is described on page 189 of WO2014028459A1 and on page 123 of WO2014116845A1.
  • Potency for Splicing Modulation of FoxM1 Gene is Linearly Correlated to Potency of Splicing Modulation of SMN2 Gene
  • It has surprisingly been found that the potency of all compounds investigated to modulate splicing of SMN2 gene is linearly related to the potency to modulate splicing of FoxM1 gene.
  • FIG. 2 shows a graph wherein the half-maximal effects for the FoxM1_ΔVIIa splice variant (IC50) have been plotted versus the half-maximal effects for the SMN protein (EC50).
  • A regression analysis of the values has resulted in a linear correlation according to the Equation 1:

  • Y=0.102*X+15.2  (Equation 1)
  • With Y=log(FoxM1_ΔVIIa IC50) and X=log(SMN protein EC50), this linear correlation allows the calculation of FoxM1_ΔVIIa IC50 values from SMN protein EC50 values according to Equation 2:

  • FoxM1_ΔVIIa IC50=10(0.102*log(SMN protein EC50)+15.2)  (Equation 2)
  • The slope of the linear correlation of Equation 1 is 0.102. Thereby the slope of the linear correlation suggests that on average, a 10-fold higher concentration (1/0.102=9.8) of each compound is needed to achieve 50% of splicing correction in the FoxM1 gene as compared to the SMN2 gene.
