Abstract: Compounds for tumor imaging (e g , magnetic resonance (MR) and fluorescence) that may be used in combination with other methods to treat an individual having or suspected of having cancer (e.g., various forms of cancer, such as, for example, solid tumors). Compounds may have the following structure: (I) or a salt, a partial salt, a hydrate, a polymorph, an isomer (e.g., a structural or stereoisomer), or a mixture thereof, where R? is an aryl group or heteroaryl group having a halogen group (e.g., I or 124I), X is chosen from O, S, or NH, n is 1-6 (e.g., 1, 2, 3, 4, 5, or 6), the dotted carbon is chiral and is R or S.

Abstract: A composition comprising PAA nanoparticles containing a post loaded tetrapyrollic photosensitizer and a postloaded imaging agent and methods for making and using same.

Abstract: A PAA nanoparticle containing a covalently linked fluorescent dye and a post-loaded tetrapyrrolic photosensitizer.

Abstract: A composition comprising PAA nanoparticles containing a post loaded tetrapyrollic photosensitizer and an imaging agent and methods for making and using same.

Abstract: A compound that is a conjugate of an antagonist to an integrin expressed by a tumor cell and at least one of a tumor avid tetrapyrollic photosensitizer, a fluorescent dye, and a radioisotope labeled moiety wherein the radioisotope is 11C, 18F, 64Cu, 124I, 99Tc, 111In or GdIII and its method of use for diagnosing, imaging and/or treating hyperproliferative tissue such as tumors. Preferably the photosensitizer is a tumor avid tetrapyrollic photosensitizer, e.g. a porphyrin, chlorin or bacteriochlorin, e.g. pheophorbides and pyropheophorbides. Such conjugates have extreme tumor avidity and can be used to inhibit or completely destroy the tumor by light absorption. The integrin is usually ?v?3, ?5?1, ?v?5, ?4?1, or ?2?1. Preferably, the antagonist is an RGD peptide or another antagonist that may be synthetic such as a 4-{2-(3,4,5,6-tetra-hydropyrimidin-2-ylamino)ethyloxy}-benzoyl]amino-2-(S)-amino-ethyl-sulfonylamino group.

Abstract: PAA nanoparticles containing at least one tetrapyrrolic photosensitizer and at least one PET imaging agent.

Abstract: A PAA nanoparticle containing a covalently linked fluorescent dye and a post-loaded tetrapyrrolic photosensitizer.

Abstract: This invention describes a first report on the synthesis of certain 124I-labelled photosensitizers related to chlorines and bacteriochlorins with long wavelength absorption in the range of 660-800 nm. In preliminary studies, these compounds show a great potential for tumor detection by positron emission tomography (PET) and treatment by photodynamic therapy (PDT). The development of tumor imaging or improved photodynamic therapy agent(s) itself represent an important step, but a dual function agent (PET imaging and PDT) provides the potential for diagnostic body scan followed by targeted therapy.

Abstract: This invention relates to a method for synthesizing Iodine-124 and also a class of radiopharmaceutical which, by virtue of an Iodine-124 label, can be used for both diagnostic and therapeutic purposes. The method comprises an innovative technique for preparing an irradiation target, irradiating the prepared target, and finally collecting Iodine-124 created by the irradiation. The method of this invention provides Iodine-124 in sufficient yields and radionuclidic purity that can be used with positron emission tomography. The invention further relates to the use of Iodine-124 in a chemical form incorporated into organic and inorganic radiopharmaceuticals.
