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.
  • Data represent means ⁇ standard error of the mean (SEM) of 3-9 independent observations. Data was generated as described in Example 1.

  • 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.
  • the term “one or more” means from one substituent to the highest possible number of substitution, i.e. replacement of one hydrogen up to replacement of all hydrogens by substituents.

  • SMA 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.
