Patent ID: 7229979

Claim:
A method of reduction or treatment of restenosis comprising: delivering an intravascular stent to a vascular lumen of a host in need thereof, wherein said stent is coated with an effective amount in the range of from 0.1 micrograms to 1000 micrograms of a compound having the formula: wherein R is selected from the group consisting of: a) H or acetyl, b) P(O)(OH) 2 , c) P(O)(OH)(OM), wherein M is selected from the group consisting of an alkali metal salt and an alkaline earth metal salt, d) P(O)OM 2 wherein M is each independently selected from the group consisting of alkali metal salts and alkaline earth metal salts, e) Alkyl of 1 to 12 carbon atoms having 0 to 6 double bonds, said alkyl selected from the group consisting of substituted, unsubstituted, straight chain and branched alkyls, f) (CH 2 )n morpholine, wherein n=1-4, g) morpholinomethylphenyl, ortho-aminophenyl or ortho-hydroxyphenyl, h) (CH 2 )n COOR 2 wherein n=1-4, R 2 is each selected from the group consisting of H, an alkali metal salt, an alkaline earth metal salt, NH 4 + and N+(R 3 ) 4 wherein R 3 is each independently selected from the group consisting of H and an alkyl of 1 to 4 carbon atoms, and i) COR 1 wherein R 1 is selected from the group consisting of H, (CH 2 )n CH 3 wherein n=0-6, and (CH 2 )n COOR 2 wherein n=1-4 and R 2 is each selected from the group consisting of H, an alkali metal salt, an alkaline earth metal salt, NH 4 +, N+(R 3 ) 4 and (CH 2 )n N+(R 3 ) 4 , wherein n=1-4 and R 3 is each independently selected from the group consisting of H and an alkyl of 1 to 4 carbon atoms, wherein the effective amount is to reduce or treat restenosis.
