ABSTRACT:
Compounds exhibiting angiogenic properties incorporating the structure of Formula I:in-line-formulae description="In-line Formulae" end="lead"?R3—NH—NH—C(═O)—R2—P—R1 (I)in-line-formulae description="In-line Formulae" end="tail"?wherein P is a water-soluble, biodegradable polymer, R1is hydrogen, lower alkyl, lower alkoxy or —R2—C(═O)—NH—NH—R3; each R2is independently —CH2—, —NH— or O; and each R3is independently hydrogen or a residue of a naturally occurring alpha-L-amino acid or dipeptide thereof. Polymer networks crosslinked with hydrazide compounds are also disclosed, together with implantable medical devices incorporating the compounds and crosslinked polymers, and angiogenesis-promoting treatment methods, including wound-treatment methods.
