Abstract
A C-nitroso moiety derived from a carbon acid with a pKa less than about 25 is bound in a biocompatible polymer as an ester or ether to a pendant hydroxyl group, as an ester to a pendant carboxylic acid or as an amine or amide to a pendant amine moiety. The polymer with c-nitroso moiety bound thereto can be coated on a medical device and/or used for prophylaxis of a patient at risk for restenosis. A c-nitroso moiety bound as amide to polyisobutylene amine substituted styrene copolymer is described in detail.
Claims6
A biocompatible polymer wherein a proton of a carbon acid with a pKa less than about 25 is replaced by a nitroso to provide a C-nitroso moiety which is bound as an ester or as an ether to a pendant hydroxyl group, as an ester to a pendant carboxylic acid or as an amine or an amide to a pendant amino moiety, said polymer, having a weight average molecular weight ranging from 50,000 to 500,000.
