Definitions

  • the present invention relates to pyridine and pyrimidine derivatives having an inhibitory / suppressing action on TTK (TTK protein kinase) activity.
  • the present invention relates to a medicament comprising this pyridine and pyrimidine derivative.
  • Protein kinases are enzymes that add (phosphorylate) phosphate groups to other protein molecules. Protein kinases have an activity of transferring a phosphate group from ATP to a hydroxyl group at an amino acid residue in a protein molecule to covalently bond it. Many protein kinases react with hydroxyl groups of serine and threonine in protein molecules (serine / threonine kinase), react with hydroxyl groups of tyrosine (tyrosine kinase), react with all three types (dual specificity) Kinase). The activity of protein kinases is precisely regulated, and protein kinases themselves may be regulated by phosphorylation. These modulations are caused by binding of other activating (or suppressing) proteins and low molecular weight compounds, localization changes in cells, and the like. Kinase dysfunction often causes illness.
  • TTK protein kinase is a bispecific kinase that phosphorylates serine, threonine and tyrosine residues in a protein serving as a substrate (see, for example, Non-Patent Document 1).
  • Kinase domains required for expressing kinase activity are known (see, for example, Non-Patent Documents 1 and 2).

  • TTK expression correlates with cell proliferation and plays a role in cell cycle control.
  • Patent Document 1 describes that TTK is expressed in malignant ovarian cancer and a screening method including a step of measuring the expression level of TTK.
  • Patent Document 2 discloses an application relating to a method for identifying cancer cells by detecting TTK activity and a method for identifying a drug that suppresses tumor growth, and TTK using tau, cdc25, and their partial peptides as a substrate as a screening method. An activity measurement method is described.
  • Patent Document 3 describes a method for measuring TTK activity using a partial peptide of p38MAPK as a substrate as a method for cleaning TTK activity. Examples of the TTK inhibitor include those described in Patent Documents 4 and 5.
  • pyridine and pyrimidine derivatives include those described in Patent Documents 6 to 59 and Non-Patent Documents 7 to 20, but none are known as TTK inhibitors, and Patent Document 60 discloses TTK inhibitory activity. Is not described.
  • An object of the present invention is to provide an effective inhibitor of TTK protein kinase, and thus to provide an effective medicine.
  • the Applicant has discovered a novel series of compounds with specific properties that inhibit the action of TTK kinase and are particularly useful in formulating pharmaceuticals for treating the above diseases. Therefore, the present compounds are useful in diseases that are considered effective by inhibiting the action of TTK kinase.
