Synthesis and Structure−Activity Relationships of Potent Thrombin Inhibitors: Piperazides of 3-Amidinophenylalanine
摘要:
Thrombin is the key enzyme in the blood coagulation system, and inhibitors of its proteolytic activity are of therapeutic interest since they are potential anticoagulants. The most potent inhibitor of the benzamidine type is N-alpha-[(2-naphthylsulfonyl)glycyl]-4-amidinophenylalanylpiperidide (NAPAP). However, NAPAP and other benzamidine derivatives do not show favorable pharmacological properties; above all, they have very low systemic bioavailability after oral administration. The goal of designing new compounds was to obtain potent inhibitors with improved pharmacokinetic properties. Piperazide derivatives of 3-amidinophenylalanine as the key building block were synthesized. The piperazine moiety opened the possibility to introduce quite different substituents on the second nitrogen using common synthetic procedures. Some of the newly synthesized compounds are potent inhibitors of thrombin and offer an approach to study structure-function relationships for inhibition of thrombin and related enzymes and for the improvement of their pharmacokinetic properties.
Certain sulfonamide compounds are dual CCK1/CCK2 inhibitors useful in the treatment of CCK1/CCK2 mediated diseases.

β-Tryptase, a mast-cell specific serine protease with trypsin-like activity, has emerged in the last years as a promising novel therapeutic target in the field of allergic inflammation. Recently, we have developed a potent and selective β-tryptase inhibitor based on the naturalproductcyclotheonamide E4 by implementing a basic P3 residue that addresses the determinants of the extended substrate specificity
The invention relates to the use of derivatives of 3-amidinophenylalanine as urokinase inhibitors for treating malignant tumors and the formation of metastases.
