Abstract

See full text

Fluorescent probes based on N-heterocyclic bisphosphonates or their phosphonocarboxylate analogues are provided. The probes have variable spectroscopic properties, bone mineral binding affinities, and pharmacological activities. Methods for preparing the probes include the use of two complementary linking strategies, one involving an amino group and the other involving a chloride group as a precursor to an amino group. In other versions, bifunctional N-heterocyclic bisphosphonates are provided having an amino group and an azido group as linking moieties. In some versions, the linking chemistry allows attachment of a wide selection of fluorescent dyes in the visible to near-infrared range to any of three clinically important heterocyclic bisphosphonates.
