Definitions

  • the present invention relates to non-steroidal compounds, a process for their preparation, pharmaceutical compositions comprising the compounds and the use of the compounds for the manufacture of a medicament, particularly for the treatment of inflammation and/or allergic conditions.
  • Nuclear receptors are a class of structurally related proteins involved in the regulation of gene expression.
  • the steroid hormone receptors are a subset of this family whose natural ligands typically comprise endogenous steroids such as estradiol (estrogen receptor), progesterone (progesterone receptor) and Cortisol (glucocorticoid receptor).
  • estradiol estradiol
  • progesterone progesterone receptor
  • Cortisol glucocorticoid receptor
  • Glucocorticoids exert their actions at the glucocorticoid receptor (GR) through at least two intracellular mechanisms, transactivation and transrepression (see: Schacke, H., Docke, W-D. & Asadullah, K. (2002) Pharmacol and Therapeutics 96:23-43; Ray, A., Siegel, M. D., Prefontaine, K.E. & Ray, P. (1995) Chest 107:139S; and Konig, H., Ponta, H., Rahmsdorf, HJ. & Herrlich, P. (1992) EMBO J 11 :2241-2246).
  • GR glucocorticoid receptor
  • Transactivation involves direct binding of the glucocorticoid receptor to distinct deoxyribonucleic acid (DNA) glucocorticoid response elements (GREs) within gene promoters, usually but not always increasing the transcription of the downstream gene product.
  • GREs deoxyribonucleic acid
  • the GR can also regulate gene expression through an additional pathway (transrepression) in which the GR does not bind directly to DNA.
  • This mechanism involves interaction of the GR with other transcription factors, in particular NFkB and AP1 , leading to inhibition of their pro- transcriptional activity (Schacke, H., Docke, W-D. & Asadullah, K. (2002) Pharmacol and Therapeutics 96:23-43; and Ray, A., Siegel, M.
  • glucocorticoids Despite the effectiveness of glucocorticoids in treating a wide range of conditions, a number of side-effects are associated with pathological increases in endogenous Cortisol or the use of exogenous, and particularly systemically administered, glucocorticoids. These include reduction in bone mineral density (Wong, C.A., Walsh, LJ. , Smith, CJ. P. et al. (2000) Lancet 355:1399-1403), slowing of growth (Allen, D. B. (2000) Allergy 55: suppl 62, 15-18), skin bruising (Pauwels, R.A., Lofdahl, C-G., Latinen, L.A. et al.
