Abstract

Abstract This invention provides a process for preparing a fibrin-adsorable protein-urokinase complex characterized by reacting a protein adsorbable by fibrin with urokinase in the presence of a protein coupling reagent represented by the formula wherein R is phenylene or cycloalkylene, A is lower alkylene, B is lower alkylene which may optionally be substituted by lower alkylthio or phenyl-lower alkylthio, and ℓ, m and n are each 0 or 1 provided that ℓ, m and n are not 0 at the same time. The complex is useful as a thrombolytic agent.

Claims Analysis

Total Claims: 9
Claim 1
Independent Claim 79 words
A process for preparing a fibrin-adsorable protein-urokinase complex characterized by reacting a protein adsorbable by fibrin with urokinase in the presence of a protein coupling reagent represented - by the formula wherein R is phenylene or cycloalkylene, A is lower alkylene, B is lower alkylene which may optionally be substituted by lower alkylthio or phenyl-lower alkylthio, and ℓ, m and n are each 0 or 1 provided that 1, m and n are not 0 at the same time.
Claim 2
Dependent Claim 79 words
A process for preparing a fibrin-adsorable protein-urokinase complex characterized by reacting a protein adsorbable by fibrin with urokinase in the presence of a protein coupling reagent represented - by the formula wherein R is phenylene or cycloalkylene, A is lower alkylene, B is lower alkylene which may optionally be substituted by lower alkylthio or phenyl-lower alkylthio, and ℓ, m and n are each 0 or 1 provided that 1, m and n are not 0 at the same time.
Claim 3
Dependent Claim 34 words
A process as defined in claim 1 wherein the protein coupling reagent is a compound of the formula wherein A and B each represent lower alkylene, ℓ and m each are 0 or 1.
Claim 4
Dependent Claim 18 words
A process as defined in claim 1 wherein the protein adsorbable by fibrin is a plasmin heavy chain.
Claim 5
Dependent Claim 17 words
A process as defined in claim 1 wherein urokinase is low molecular weight-urokinase or high molecular weight-urokinase.
Claim 6
Dependent Claim 20 words
A process as defined in claims 1 or 2 wherein A represents alkylene groups having 1 to 6 carbon atoms.
Claim 7
Dependent Claim 44 words
A process as defined in claim 1 wherein B represents alkylene groups having 1 to 6 carbon atoms which may optionally be substituted with alkylthio having 1 to 6 carbon atoms or with phenyl-alkylthio wherein the alkyl moiety has 1 to 6 carbon atoms.
Claim 8
Dependent Claim 13 words
A fibrin-adsorbable protein-urokinase complex prepared by a process as defined in claim 1.
Claim 9
Dependent Claim 25 words
A pharmaceutical composition containing the fibrin-adsorbable protein-urokinase complex prepared by a process as defined in claim 1 in combination with a pharmaceutically acceptable, non-toxic carrier.
