Definitions

  • the present invention concerns bicyclic and heterocyclic derivatives, processes for preparing them, pharmaceutical compositions containing them and their use as pharmaceuticals.
  • the integrin ⁇ 4 is predominantly expressed on eosinophils, T and B lymphocytes, monocytes and basophils. It binds primarily to the vascular cell surface adhesion molecule VCAM-1 that is expressed on endothelium in response to inflammatory cytokines (TNF- ⁇ , IL-1 and selectively IL-4 and IL-13), extracellular matrix protein fibronectin and a cell surface adhesion molecule MAdCAM-1 that is expressed preferentially in the gastrointestinal track.
  • ⁇ 4 is not expressed on circulating neutrophils, which are the first defence against infection, it is a target for the pharmacological control of inflammatory diseases.
  • Several in vitro and in vivo studies have indicated an important role of ⁇ 4 in cell adhesion mediated inflammatory pathologies and that blocking its function is beneficial. Diseases include asthma, multiple sclerosis (MS), rheumatoid arthritis (RA) or inflammatory bowel diseases.
  • ⁇ 4 is also expressed on leukemic cells that show increased survival through binding to fibronectin expressed on bone marrow stormal cells. Blocking this interaction in the presence of chemotherapy is beneficial in preventing relapse of acute myelogenous leukemia.
  • ⁇ .4 and VCAM-1 have also been identified in smooth muscle cells from intimal atherosclerotic thickening of adult aorta. Blocking this interaction is beneficial in preventing smooth muscle differentiation and atherosclerosis.
  • the interaction of ⁇ 4 on inflammatory cells with fibronectin has also been shown to increase chronic allograft failure. Blocking this interaction is beneficial in supporting transplant survival.

  • Methyl-(2S)-2-[amino]-3-[2-(2,6-dichlorophenyl)-6-quinolinyl]propanoate (RN 623144-33-2) (50mg) is dissolved in methanol (5ml) TEA (0.16ml) and 4-Chloro-2- thiomethylypyrimidine (0.24ml) is added and the reaction is heated using microwave irradiation to 16O 0 C for 15 mins. On cooling 2N NaOH solution (2ml) is added and the reaction is stirred at RT overnight. The solvent is removed and the resulting slurry is purified by mass triggered prep HPLC (Method B) to yield the title compound (20mg) as a white solid.
  • the following protein assay is used to demonstrate the potency of the compounds according to the invention.
  • an IC50 value is determined for each test compound and represents the concentration of compound necessary to achieve 50% inhibition of bindingVCAM-mFc / a4b1-hFc protein binding assay in DELFIA format.
  • test compound IC50 values calculated.
  • the compounds of the invention are tested in this assay and show IC50 values of 0.5 ⁇ M and below.
