  • the present invention relates to triazolyl-thio-ethanone derivatives which inhibit the activity of protein phosphatases (PPases) such as PTPlB (protein tyrosine phosphatase IB), LAR (leukocyte antigen-related), CD45 (cluster of differentiation 45), Yop (Yersinia enterocolytica tyrosine phosphatase), PPl (protein phosphatases 1), VHR (vaccinia human-related) as well as Cdc25 (cell division cycle 25), and more particularly, to a composition for the prevention and treatment of cancer, which contains the triazolyl-thio-ethanone derivatives and pharmaceutically acceptable salts thereof as an active ingredient.

  • Protein phosphorylation and dephosphorylation are widely known as important regulatory mechanisms which are used for cellular signal transduction in various stages of the cellular functions. On the whole, cellular signals are mediated through phosphorylation and dephosphorylation, catalyzed by kinases and protein phosphatases, respectively. Due to their characteristic activities, particularly, protein phosphatases (PPases), which are responsible for dephosphorylation, are known to play pivotal roles in the in vivo modulation and regulation of fundamental cellular signaling mechanisms for metabolism, growth, proliferation and differentiation.
  • PPases protein phosphatases
  • Cdc25 (Cdc25A, Cdc25B, and Cdc25C), functioning to remove phosphate from tyrosine, PTPlB, Prl-3, LAR, CD45, Cdc25A, Yop, PPl, VHR and the like.
  • Cdc25 phosphatase is a kind of dual specific phosphatase for acting on both phosphor-tyrosine and phosphor-threonine.
  • the Cdc25 phosphatase is responsible for the activation of cyclin dependent kinase (CDK) by removing inhibitory phosphate from tyrosine and threonine residues of CDK, which is implicated in the cell division cycle.
  • CDK cyclin dependent kinase
  • a high level of CDK induces the activation of the MPF (M phase promoting factor) to increase the miotic activity in the M phase of cell cycle, resulting in cell pro- liferation. Accordingly, inhibiting the activity of the Cdc25 phosphatase interfere with cell division to thus prevent cell proliferation.
  • MPF M phase promoting factor
  • Cdc25 has been reported to have three homologues, Cdc25A, Cdc25B, and Cdc25C, in human cells.
  • Cdc25A or Cdc25B is inferred to play an important role in carcinogenesis because it is the most highly expressed in cancer cells, for example, breast cancer, rectal cancer, non- Hodgkin's lymphoma, prostate cancer, pancreatic ductal adenocarcinoma, lung cancer, and the like, and recent studies have revealed that Cdc25 A is also included in the adhesion-dependent proliferation of sensitive myeloid leukaemia cells.
  • Cdc25 inhibitors can be targets for developing anticancer agents, extensive and intensive research has been studied on the inhibitors (Ontani, T. et al., J. of Antibiotics 2000, 53, 337; Lazo, J. S. et al., Bioorg. Mded. Chem. Lett. 2000, 8, 1451).
  • PTPlB as the first identified intercellular protein phophastase was isolated from the human placenta and found to have a molecular weight of -50 kDa, and then cloned.
  • PTPlB is highly expressed in various human cells. Particularly, PTPlB acts to inhibit the phosphorylation not only of insulin receptor (IR) but also of insulin receptor substrate (IRS-I) in the signal transduction pathway of insulin. It was demonstrated through the biochemical experiment conducted by Kennedy and Ramachandran, in which PTPlB knock-out mice were observed to exhibit the increase of insulin sensitivity and, when injected with insulin, to increase the phosphorylation of insulin receptors in hepatic and muscular cells (Science 1999, 283, 1544).

  • IRS-I insulin receptor substrate
  • Diabetes mellitus type II an insulin-indepedent diabetes, is a metabolic disorder that is primarily characterized by insulin resistance of the organs (muscles, liver, lipocytes) where insulin disfunctions, although the pancreas normally secretes insulin.
  • the dephosphorylation of the insulin receptor (IR) was found to be directly responsible for insulin resistance and be implicated in diabetes mellitus type II. Having potential activity to overcome insulin resistance and normalize the level of glucose and insulin in the blood without causing hypoglycemia, accordingly, PTPlB inhibitors, acting against the dephosphorylation of IR, have been extensively studied with the aim of developing therapeutic agents for diabetes mellitus type II.
  • CD45 plays an essential role in terminating the signal transduction responsible for the uncontrollable growth of cells.
  • CD45 a transmembrane PTPase (Protein Tyrosine Phosphatase) was known as an important role in signal transduction in T-cell or B -cells.
  • JAK Janus kinase
  • STAT signal transducer and activators of transcription
  • CD45 negatively regulates interleukin-3 -mediated cellular proliferation, erythropoietin-dependent hematopoieisis and antiviral responses. This indicates that CD45 suppresses the activity of the immune system of attacking foreign invaders, leading to the suppression of cancer cell proliferation and autoimmune diseases. Based on this finding, CD45 inhibitors can be available to prevent transplant rejection. In fact, extensive research into CD45 inhibitors has been conducted and the results thereof are disclosed in many patents and articles, issued to AstraZeneca Company (W 0 0146125, 0145681, 0145680, R.
