Abstract: In one aspect, biocompatible matrices such as sol-gels encapsulating a reaction center may be administered to a subject for conversion of prodrugs into biologically active agents. In certain embodiments, the biocompatible matrices of the present invention are sol-gels. In one embodiment, the enzyme L-amino acid decarboxylase is encapsulated and implanted in the brain to convert L-dopa to dopamine for treatment of Parkinson's disease.

Abstract: One aspect of the invention relates to complexes of technetium (Tc) and rhenium (Re) with various heteroaromatic ligands, e.g., quinolinyl and isoquinolinyl ligands, and their use in fluoresence and radioimaging for a variety of clinical diagnostic applications, as well as radiopharmaceuticals for therapeutic applications. Another aspect of the invention relates to quinolinyl and isoquinolinyl ligands that form a portion of the aforementioned complexes. Methods for the preparation of the technetium and rhenium complexes are also described. Another aspect of the invention relates to quinolinyl and isoquinolinyl ligands based on derivatized lysine, alanine and bis-amino acids for conjugation to small peptides by solid phase synthetic methods. Additionally, the invention relates to methods for imaging regions of a mammal using the complexes of the invention.

Abstract: The present invention provides novel imaging agents for clinical diagnosis of injuries and diseases, in the form of a radionuclide in spatial proximity to a substantially pure stereoisomer of a fatty acid analog. The invention also provides methods for using the novel imaging agents, and kits containing one or more of the novel imaging agents of the invention.
