Patent ID: 7858077

Claim:
A polymer comprising a unit having the formula: AR—O—Y—R′ AR—O— is a biologically active phenolic moiety selected from the group consisting of isopimpinellin, isoflavones, resveratrol, and bioflavonoids substituted with a functional group selected from the group consisting of alkoxy, benzyloxy, aldehyde, halogen, carboxylic acid, —NO 2 , —NH 2 , —NHCOCH 3 , —NH—Y—R′, and a combination thereof, Y represents a member selected from the group consisting of: —COCH 2 O— (glycolic ester moiety) —COCH(CH 3 )O— (lactic ester moiety) —COCH 2 OCH 2 CH 2 O— (dioxanone ester moiety) —COCH 2 CH 2 CH 2 CH 2 CH 2 O— (caprolactone ester moiety) —CO(CH 2 ) m O— where m is an integer between 2-4 and 6-24 inclusive, —COCH 2 —O—(CH 2 CH 2 O) n — where n is an integer between 2 and 24, inclusive; and the carbonyl end of Y is attached to the O— of said biologically active phenolic moiety to form an ester linkage; and R′ is either hydrogen or a benzyl or an alkyl group, the alkyl group being either straight-chained or branched.
