Abstract

Abstract TGF-beta activators and TGF-beta production stimulators are employed to prevent or treat conditions characterized by inappropriate proliferation of smooth muscle cells, such as the prevention or reduction of restenosis following angioplasty or other vascular trauma. Such TGF-beta activators and production stimulators inhibit abnormal proliferation of smooth muscle cells. TGF-beta activators or production stimulators that are not characterized by an undesirable systemic toxicity profile at a prophylactic dose are also amenable to chronic use for prophylactic purposes with respect to disease states involving proliferation of vascular smooth muscle cells over time. Further provided is a method for upregulating cellular mRNA coding for TGF-beta.

Claims Analysis

Total Claims: 20
Claim 1
Independent Claim 46 words
A therapeutic method to treat procedural vascular trauma, comprising orally administering to a mammal subjected to the vascular trauma an amount of an agent effective upon oral administration to elevate the level of TGF-beta so as to inhibit the pathological proliferation of vascular smooth muscle cells.
Claim 2
Dependent Claim 46 words
A therapeutic method to treat procedural vascular trauma, comprising orally administering to a mammal subjected to the vascular trauma an amount of an agent effective upon oral administration to elevate the level of TGF-beta so as to inhibit the pathological proliferation of vascular smooth muscle cells.
Claim 3
Dependent Claim 19 words
The therapeutic method of claim 1 wherein stenosis or restenosis of a mammalian blood vessel is reduced or inhibited.
Claim 4
Dependent Claim 19 words
The therapeutic method of claim 1 wherein the procedural vascular trauma is due to a graft or transplant procedure.
Claim 5
Dependent Claim 13 words
The therapeutic method of claim 1 wherein the procedural vascular trauma is angioplasty.
Claim 6
Dependent Claim 19 words
The therapeutic method of claim 1 wherein the agent increases the cell cycle time of the smooth muscle cells.
Claim 7
Dependent Claim 20 words
The therapeutic method of claim 1 wherein the agent elevates the level of TGF-beta by increasing production of TGF-beta mRNA.
Claim 8
Dependent Claim 23 words
The therapeutic method of claim 1 comprising administering a series of doses of the agent effective to maintain an elevated level of TGF-beta.
Claim 9
Dependent Claim 14 words
The method of claim 7 wherein the TGF-beta which is elevated is active TGF-beta.
Claim 10
Dependent Claim 15 words
The therapeutic method of claim 1 wherein the agent comprises trans-2-[4-1,2-diphenyl-1-butenyl)phenoxy]-N,N-dimethyl-ethylamine or an analog thereof.
Claim 11
Dependent Claim 17 words
The therapeutic method of claim 1 wherein the agent does not include heparin or a heparin peptide.
Claim 12
Independent Claim 34 words
A method for reducing or inhibiting restenosis associated with an angioplasty procedure, which method comprises orally administering to a mammal an amount of an agent effective upon oral administration to elevate levels of TGF-beta.
Claim 13
Independent Claim 34 words
A method for reducing or inhibiting restenosis associated with an angioplasty procedure, which method comprises orally administering to a mammal an amount of an agent effective upon oral administration to elevate levels of TGF-beta.
Claim 14
Dependent Claim 17 words
The method of claim 11 wherein the agent is effective to elevate the level of active TGF-beta.
Claim 15
Dependent Claim 14 words
The method of claim 11 wherein the agent comprises trans-2-[4-(1,2-diphenyl-1-butenyl)phenoxy]-N,N-dimethyl-ethylamine or an analog thereof.
Claim 16
Dependent Claim 16 words
The method of claim 11 wherein the agent does not include heparin or a heparin peptide.
Claim 17
Dependent Claim 28 words
The method of claim 11 wherein the agent is orally administered in a series of doses effective to inhibit vascular smooth muscle cell proliferation associated with the procedure.
Claim 18
Dependent Claim 19 words
The method of claim 1 or 11 wherein the agent increases the cleavage of the latent form of TGF-beta.
Claim 19
Dependent Claim 15 words
The method of claim 1 or 11 wherein the agent increases the bioavailability of TGF-beta.
Claim 20
Dependent Claim 19 words
The therapeutic method of claim 1 or 11 wherein the agent is administered before, during, or after said procedure.
