and their pharmaceutically usable salts and esters.
The compounds of formula I and their pharmaceutically usable salts and esters are novel and have valuable pharmacological properties. In particular, they inhibit the binding of adhesive proteins such as fibrinogen, vitronectin, von Willebrand factor, fibronectin, thrombospondin and osteopontin to the vitronectin receptors (such as e.g. &agr;

, etc.) on the surface of various types of cell. All of the compounds of formula I that were tested inhibited the binding of fibrinogen to the vitronectin receptor &agr;

in the assay described below. Therefore these compounds can be used as vitronectin receptor agonists in the treatment and prophylaxis of illnesses which are caused by a malfunction of the binding of adhesive proteins to vitronectin receptors. In particular, they can be used as vitronectin receptor antagonists in the prophylaxis or treatment of neoplasms, tumor metastasis, tumor growth, osteoporosis, Paget's disease, diabetic retinopathy, macular degeneration, restenosis following vascular intervention, psoriasis, arthritis, fibrosis, kidney failure as well as infections caused by viruses, bacteria or fungi.
Objects of the present invention are the compounds of formula I and their aforementioned salts and esters per se and their use as therapeutically active substances, a process for the manufacture of the said compounds, intermediates, pharmaceutical compositions, medicaments containing the said compounds, their salts or esters, the use of the said compounds, solvates and salts for the prophylaxis and/or therapy of illnesses, especially in the treatment or prophylaxis of, for example, neoplasms, tumor metasis, tumor growth, osteoporosis, Paget's disease, diabetic retinopathy, macular degeneration, restenosis following vascular intervention, psoriasis, arthritis, fibrosis, kidney failure as well as infections caused by viruses, bacteria or fungi, and the use of the said compounds and salts for the production of medicaments for the treatment or prophylaxis of, for example, neoplasms, tumor metasis, tumor growth, osteoporosis, Paget's disease, diabetic retinopathy, restenosis following vascular intervention, psoriasis, arthritis, fibrosis, kidney failure as well as infections caused by viruses, bacteria or fungi.
DETAILED DESCRIPTION OF THE INVENTION
In the present description the term “alkyl”, alone or in combination, signifies a straight-chain or branched-chain alkyl group with 1 to 8 carbon atoms, preferably a straight or branched-chain alkyl group with 1-4 carbon atoms. Examples of straight-chain and branched C
