Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
110 words
A method of preventing or treating hyperproliferative vascular disease in a mammal in need thereof, comprising administering an amount, effective to inhibit intimal thickening in said mammal, of a compound of the formula I or II ##STR6## wherein R 1 denotes a) methyl, b) (C 3 -C 6 )-cycloalkyl or c) (C 2 -C 6 )-alkyl, having at least 1 double or triple bond between the carbon atoms, R 2 denotes a) --CF 3 or b) --CN, R 3 denotes a) (C 1 -C 4 )- alkyl or b) hydrogen atom, X denotes a) --CH-group or b) nitrogen atom, or a physiologically tolerable salt of a compound of formula II.
Claim 2
Independent Claim
110 words
A method of preventing or treating hyperproliferative vascular disease in a mammal in need thereof, comprising administering an amount, effective to inhibit intimal thickening in said mammal, of a compound of the formula I or II ##STR6## wherein R 1 denotes a) methyl, b) (C 3 -C 6 )-cycloalkyl or c) (C 2 -C 6 )-alkyl, having at least 1 double or triple bond between the carbon atoms, R 2 denotes a) --CF 3 or b) --CN, R 3 denotes a) (C 1 -C 4 )- alkyl or b) hydrogen atom, X denotes a) --CH-group or b) nitrogen atom, or a physiologically tolerable salt of a compound of formula II.
Claim 3
Dependent Claim
38 words
The method of claim 1, wherein R 1 denotes a) methyl, b) cyclopropyl or c) --CH 2 --CH 2 --C.tbd.CH, R 2 denotes --CF 3 , R 3 denotes methyl or hydrogen atom and X denotes --CH-- group.
Claim 4
Dependent Claim
24 words
The method of claim 1, wherein the compound of the formula I or II is selected from the group consisting of N-(4-trifluoromethylphenyl)-2-cyano-3-hydroxycrotonamide and N-(4-trifluoromethylphenyl)-5-methylisoxazole-4-carboxamide.
Claim 5
Dependent Claim
32 words
The method of claim 1, wherein the administering is accomplished orally, parenterally, intravascularly, intranasally, intrabronchially, transdermally, rectally, or via a vascular stent impregnated with a compound of the formula I or II.
Claim 6
Dependent Claim
27 words
The method of claim 1, wherein the compound of the formula I or II is administered concurrent with said mammal undergoing a percutaneous transluminal coronary angioplasty procedure.
Claim 7
Dependent Claim
28 words
The method of claim 5, which further comprises administering the compound of the formula I or II subsequent to said mammal undergoing a percutaneous transluminal coronary angioplasty procedure.
Claim 8
Dependent Claim
26 words
The method of claim 1, wherein the hyperproliferative vascular disease is selected from the group consisting of intimal smooth muscle cell hyperplasia, restenosis, and vascular occlusion.
Claim 9
Dependent Claim
31 words
The method of claim 1, wherein the compound of the formula I or II is administered prior to, concurrent with or subsequent to said mammal sustaining a biologically mediated vascular injury.
Claim 10
Dependent Claim
31 words
The method of claim 1, wherein a compound of the formula I or II is administered prior to, concurrent with or subsequent to said mammal sustaining a mechanically mediated vascular injury.
