Definitions

  • the present invention relates to pyrimidine derivatives, a process for their preparation, pharmaceutical compositions containing them, a process for preparing the pharmaceutical compositions, and their use in therapy and the treating of conditions mediated by polo-like kinases.
  • Cyclin dependent kinase family have long been considered the master regulators of the cell cycle but an increasing number of diverse protein kinases are emerging as critical components of cell cycle progression. Among these are the polo-like kinase family (Plks), serine/threonine kinases that play multiple roles in regulating progress through cell cycle. In man, four distinct family members have been identified. These are Plkl, Plk2 (Snk), Plk3 (Fnk, Prk) and Plk4 (Sak).
  • Plkl The best characterized family member is Plkl which is conserved from yeast to man and has been implicated in numerous mitotic processes including activation of Cdc25C and Cdkl/Cyclin B at the G2-M transition, centrosome maturation, spindle formation and assembly (Glover et al. 1998, Genes Dev. 12:3777-87; Barr et al 2004, Nat. Rev. MoI. Cell Biol 5:429-441). In the later stages of mitosis Plkl is involved in separation of sister chromatids, activation of components of the anaphase-promoting complex and septin regulation during cytokinesis (van Vugt & Medema 2005, Oncogene 24:2844-2859).
  • Plkl is over-expressed in a broad spectrum of cancer types including breast, colorectal, endometrial, oesophageal, ovarian, prostate, pancreatic, non small cell lung cancers and melanomas (Wolf et al. 1997, Oncogene 14:543-549; Knecht et al. 1999, Cancer Res. 59:2794-2797; Wolf et al. 2000, Pathol. Res. Pract. 196:753-759; Takahashi et al. 2003, Cancer Sci. 94:148-152). The expression of Plkl often correlates with poor patient prognosis.
  • Plkl inhibition has been demonstrated in studies employing both antisense oligonucleotides (ASO) and small molecule RNA (siRNA). Reduction in the level of Plkl results in the inhibition of proliferation of tumour cells and loss of cell viability both in vivo and in vitro but does not inhibit proliferation of primary cells (Spankuch-Schmitt et al 2002, Oncogene 21: 3162-3171; Elez et al 2003, Oncogene 22:69-80). Microinjection of anti-Plkl antibodies induced mitotic catastrophe in HeLa tumour cells.
  • ASO antisense oligonucleotides
  • siRNA small molecule RNA
  • Plk3 also appears to play roles in mitosis, like Plkl it has been reported to phosphorylate Cdc25C, regulate microtubule dynamics and is involved in centrosome function. Over-expression of Plk3 has been observed in both breast and ovarian carcinomas, with little or no expression in adjacent normal tissue. Increased protein level was associated with enhanced mitosis and was significantly linked to reduced median survival time of patients (Weichert et al. 2005, Virchows Arch 446: 442-450; Weichert et al. 2004 Br. J.Cancer 90:815-821).
  • PIk family members should be of therapeutic value for treatment of proliferative disease including solid tumours such as carcinomas and sarcomas and the leukaemias and lymphoid malignancies.
  • PIk inhibitors should be useful in the treatment of other disorders associated with uncontrolled cellular proliferation.
  • Pteridinone derivatives are known from the prior art as active substances with an antiproliferative activity.
  • WO 01/019825 and WO 03/020722 describe the use of pteridinone derivatives for the treatment of tumoural diseases.
  • tumours The resistance of many types of tumours calls for the development of new pharmaceutical compositions for combating tumours.
