Definitions
- New acylguanidine derivatives process for their preparation, their use as medicaments and the pharmaceutical compositions containing them.
- the present invention relates to new derivatives of 1 acylguanidines, their preparation process, their application as medicaments and the pharmaceutical compositions containing them.
- the compounds of formula (I) are compounds having pharmacological activity and are therefore usable as medicaments. They are vitronectin receptor antagonists and cell adhesion inhibitors and they inhibit bone resorption mediated by osteoclasts. They are therefore useful for the therapeutic or prophylactic treatment of diseases which are caused at least in part by an unwanted increase in bone resorption, for example osteoporosis.
- the invention further relates to the processes for preparing the compounds of formula (I), their application, in particular as a medicament and the pharmaceutical compositions containing them.
- Bone is constantly undergoing a dynamic process that includes bone resorption and bone formation. These processes are mediated via specialized cells. Bone formation is the result of the deposition of a mineral matrix by the osteoblasts and bone resorption is the result of the dissolution of this bone matrix by the osteoclasts. The majority of bone disorders are based on a disturbed balance between training bone and bone resorption. Osteoporosis is characterized by a dry loss of this bone matrix. An activated mature osteoclast resorbs the bone after adhesion to the bone matrix via the secretion of proteolytic enzyme, and of protons inside the adhesion zone, resulting in depressions or hollows in the surface of the bone which appear when the osteoclast detaches from the bone.
- Integrins are a superfamily of receptors mediating cell / cell and more particularly cell / matrix adhesion processes, including in particular ⁇ n b ⁇ 3 as a receptor for blood platelets (fibrinogen) and v ⁇ 3 as a receptor for vitronectin.
- the peptides containing the RGD motif as well as the anti v ⁇ 3 antibodies are known for their ability to inhibit the resorption of dentin and prevent adhesion of osteoclasts on mineralized matrices (Horton et al. Exp. Cell Res. (1991), 195, 368).
- the peptide Echistatin isolated from snake venom also containing an RGD motif and described as an inhibitor of osteoclast adhesion to bone is a powerful inhibitor of bone resorption in tissues in in vitro culture (Sato et al. J. Cell. Biol. (1990), 111, 1713) and in vivo in rats (Fisher et al. Endocrinology (1993), 132, 1411).
- the cx v ⁇ 3 receptor is a transmembrane glycoprotein which is expressed in a large number of cells including endothelial cells, smooth muscle cells, osteoclast and cancer cells, which thus leads to a pluripotentiality of the compounds of formula (I) according to the invention.
- the v ⁇ 3 receptors expressed at the level of the osteoclast membrane are at the base of the adhesion / resorption process, contribute to the organization of the cell cytoskeleton, and are involved in osteoporosis.
- the v ⁇ 3 receptors expressed in the smooth muscle cells of the aorta stimulate their migration towards the neointima, which leads to the formation of arteriosclerosis and the occurrence of post-angioplastic restenosis (Brown et al., cardiovascular Res. (1994), 28, 1815).
- Endothelial cells secrete growth factors which are mitogenic for the endothelium and can contribute to the formation of new blood vessels (Angiogenesis).
- the integrin v ⁇ 3 antagonists can thus lead to a regression of cancerous tumors by inducing apoptosis of the angiogenic blood vessels. (Brook et al. Cell (1994) 79, 1157).
- Patent application WO-A-94/12181 describes substituted aromatic or non-aromatic systems and WO-A-94/08577 describes substituted heterocycles as fibrinogen receptor antagonists and inhibitors of platelet aggregation.
- EP-A-528586 and EP-A-528587 describe phenylalanine derivatives substituted by an aminoalkyl or a heterocycle and WO-A-95/32710 describe aryl derivatives as inhibitors of bone resorption by osteoclasts.
- WO-A-96/00574 describes benzodiazepines and WO- A-96/00730 describes compounds which inhibit the fibrinogen receptor, in particular benzodiazepines which are linked to a 5-membered nitrogen ring as antagonists of the vitronectin receptor.
- DE-A-19654483 describes vitronectin receptor antagonists derived from tyrosine.
- De -A- 19629816.4 claims cycloalkyl derivatives as vitronectin receptor antagonists.
- Other investigations have made it possible to show that the acylguanidine derivatives of formula (I) have a strong activity as an inhibitor of the vitronectin receptor and of bone resorption produced via osteoclasts.
