Definitions

  • Novel sulfonamide derivatives as inhibitors of bone resorption and as inhibitors of cell adhesion
  • the present invention relates to sulfonamide derivatives of the formula I,
  • R 1 , R 2 , R 4 , R 5 and R 6 have the meanings indicated below, their physiologically tolerable salts and their prodrugs.
  • the compounds of the formula I are valuable pharmaceutical active compounds. They are vitronectin receptor antagonists and inhibitors of cell adhesion and inhibit bone resorption by osteoclasts. They are suitable, for example, for the therapy and prophylaxis of diseases which are caused at least partially by an undesired extent of bone resorption, for example of osteoporosis.
  • the invention furthermore relates to processes for the preparation of compounds of the formula I, their use, in particular as pharmaceutical active ingredients, and pharmaceutical preparations comprising them.
  • Bone resorption is based on the destruction of bone matrix by osteoclasts. The majority of bone disorders are based on a disturbed equilibrium between bone formation and bone resorption.
  • Osteoporosis is a disease characterized by low bone mass and enhanced bone fragility resulting in an increased risk of fractures. It results from a deficit in new bone formation versus bone resorption during the ongoing remodelling process.
  • Conventional osteoporosis treatment includes, for example, the administration of bisphosphonates, estrogens, estrogen/progesterone (hormone replacement therapy or HRT), estrogen agonists/antagonists (selective estrogen receptor modulators or SERMs), calcitonin, vitamin D analogues, parathyroid hormone, growth hormone secretagogues, or sodium fluoride (Jardine et al., Annual Reports in Medicinal Chemistry 1996, 31 , 211 ).
  • Activated osteoclasts are polynuclear cells having a diameter of up to 400 ⁇ m, which remove bone matrix. Activated osteoclasts become attached to the surface of the bone matrix and secrete proteolytic enzymes and acids into the so-called "sealing zone", the region between their cell membrane and the bone matrix. The acidic environment and the proteases cause the destruction of the bone.
  • the compounds of the formula I inhibit bone resorption by osteoclasts.
  • Integrins are a superfamily of receptors which include, inter alia, the fibrinogen receptor ⁇ Mb ⁇ 3 on the blood platelets and the vitronectin receptor ⁇ v ⁇ 3 .
  • the vitronectin receptor ⁇ v ⁇ 3 is a membrane glycoprotein which is expressed on the cell surface of a number of cells such as endothelial cells, cells of the vascular smooth musculature, osteoclasts and tumor cells.
  • the vitronectin receptor ⁇ v ⁇ 3 which is expressed on the osteoclast membrane, controls the process of attachment to the bones and bone resorption and thus contributes to osteoporosis.
  • ⁇ v ⁇ 3 in this case binds to bone matrix proteins such as osteopontin, bone sialoprotein and thrombospontin, which contain the tripeptide motif Arg-Gly-Asp (or RGD).
  • vitronectin ⁇ v ⁇ 3 on human cells of the vascular smooth musculature of the aorta stimulates the migration of these cells into the neointima, which finally leads to arteriosclerosis and restenosis after angioplasty (Brown et al., Cardiovascular Res. 1994, 28, 1815).
  • WO-A-94/12181 describes substituted aromatic or nonaromatic ring systems
  • WO-A-94/08577 describes substituted heterocycles as fibrinogen receptor antagonists and inhibitors of platelet aggregation.
  • EP-A-528586 and EP-A- 528587 disclose aminoalkyl-substituted or heterocyclyl-substituted phenylalanine derivatives
  • WO-A-95/32710 discloses aryl derivatives as inhibitors of bone resorption by osteoclasts.
  • WO-A-96/00574 describes benzodiazepines
  • WO-A-96/00730 describes fibrinogen receptor antagonist templates, in particular benzodiazepines which are linked to a nitrogen-bearing 5-membered ring, as vitronectin receptor antagonists.
  • WO-A-98/00395 (DE-A- 19654483) describes vitronectin receptor antagonists derived from a tyrosine scaffold.
  • EP-A-820991 (German patent application 19629816.4) describes cycloalkyl derivatives and European patent application 97122520.6 describes carbamic ester derivatives which are vitronectin receptor antagonists. Further investigations have shown that the sulfonamide derivatives of the formula I are particularly strong inhibitors of the vitronectin receptor and of bone resorption by osteoclasts.
