Small, Potent, and Selective Diaryl Phosphonate Inhibitors for Urokinase-Type Plasminogen Activator with In Vivo Antimetastatic Properties
摘要:
A set of small nonpeptidic diaryl phosphonate inhibitors was prepared. Some of these inhibitors show potent and highly selective irreversible uPA inhibition. The biochemical and modeling data prove that the combination of a benzylguanidine moiety with a diaryl phosphonate ester results in optimized molecules for derivatizing the serine alcohol in the uPA active site. Selected compounds show significant antimetastatic effects in the BN-472 rat mammary carcinoma model. We report in this paper a preclinical proof of concept that selective, irreversible uPA inhibitors could be valuable in antimetastatic therapy.
The present invention relates to novel compounds with inhibitory activity towards urokinase plasminogen activator (uPA); to methods for preparation of said uPA inhibitor compounds; to pharmaceutical compositions comprising said uPA inhibitor compounds; to the use of said uPA inhibitor compounds as a medicament and the use of said uPA inhibitor compounds for the preparation of a medicament for the treatment of conditions chosen from the group comprising cancer, tumour growth, tumour invasion, tumour metastasis, diabetic retinopathy, hemorrhagic atherosclerosis and inflammatory conditions, such as rheumatoid arthritis and psoriasis.
