Immobilization of an active agent on a substrate
First Claim
1. A method of immobilizing an active agent on a substrate surface, comprising the steps of:
- depositing a primer compound on a substrate, thereby forming a primed substrate;
contacting the primed substrate with a solution of a compound including a trihydroxyphenyl group, thereby forming a trihydroxyphenyl-treated primed substrate; and
contacting the trihydroxyphenyl-treated primed substrate with a solution of an active agent, thereby forming a substrate with an active agent immobilized on the surface thereof, wherein the compound including a trihydroxyphenyl group is selected from the group consisting of gallic acid, phloroglucinol carboxylic acid, gallamide, 5-methyl-benzene-1,2,3-triol, 3,4,5-trihydroxybenzaldehyde, 2,3,4-trihydroxybenzaldehyde, gallacetophenone, 3,4,5-trihydroxybenzamide, 2,3,4-trihydroxybenzoic acid, 5-hydroxydopamine hydrochloride, methyl gallate, pyrogallol, salts of the foregoing, and combinations thereof.

Abstract
The invention provides methods of immobilizing an active agent to a substrate surface, including the steps of, depositing a primer compound on a substrate, thereby forming a primed substrate, contacting the primed substrate with a solution of a compound including a trihydroxyphenyl group, thereby forming a trihydroxyphenyl-treated primed substrate, and contacting the trihydroxyphenyl-treated primed substrate with a solution of an active agent, thereby immobilizing the active agent on the substrate. Further provided are methods of immobilizing an active agent on a substrate, including the steps of providing a substrate, combining a solution of a compound including a trihydroxyphenyl group with a solution of an active agent, thereby forming a solution of an active agent-trihydroxyphenyl conjugate, and contacting the primed substrate with the solution of the active agent-trihydroxyphenyl conjugate, thereby immobilizing the active agent on the substrate. The invention further provides substrates and medical device or device components with active agents immobilized on the surface thereof.

10. A method of immobilizing an active agent on a substrate surface, comprising the steps of:
-
depositing a primer compound on the substrate thereby forming a primed substrate; combining in solution a compound including a trihydroxyphenyl group and an active agent, thereby forming a solution of an active agent-trihydroxyphenyl conjugate; and contacting the primed substrate with the solution of the active agent-trihydroxyphenyl conjugate, thereby coupling the trihydroxyphenyl group of the active agent-trihydroxyphenyl conjugate to the primed substrate and forming a substrate with an active agent immobilized on the surface thereof, wherein the compound including a trihydroxyphenyl group is selected from the group consisting of gallic acid, phloroglucinol carboxylic acid, gallamide, 5-methyl-benzene-1,2,3-triol, 3,4,5-trihydroxybenzaldehyde, 2,3,4-trihydroxybenzaldehyde, gallacetophenone, 3,4,5-trihydroxybenzamide, 2,3,4-trihydroxybenzoic acid, 5-hydroxydopamine hydrochloride, methyl gallate, pyrogallol, salts of the foregoing, and combinations thereof. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18, 19)
