Abstract: Compounds that are PSMA ligands, pharmaceutical compositions comprising these compounds, methods for treating and detecting cancers in a subject, methods for identifying cancer cells in a sample are described herein. Prostate-specific membrane antigen (PSMA) is a 120 kDa protein expressed in prostate tissues and was originally identified by reactivity with a monoclonal antibody designated 7EII-C5 (Horoszewicz et al., 1987, Anticancer Res. 7:927-935; U.S. Pat. No. 5,162,504). PSMA is characterized as a type II transmembrane protein sharing sequence identity with the transferrin receptor (Israeli et al., 1994, Cancer Res. 54:1807-1811).

Abstract: A phthalocyanine compound or targeted conjugate thereof having the formula (I).

Abstract: A system for detecting tumor margins includes a topical protease-specific, fluorescence imaging probe that is activatable by enzymatic activation to produce a visually differentiated signal upon topical application to a targeted cancer cell that secretes an enzyme that activates the protease-specific, fluorescence imaging probe, means for topically administering the imaging probe to the cancer cell; and an imaging device to detect activation of the imaging probe administered to the cancer cell.

Abstract: A system for imaging an abnormal cell and or diseased tissue after topical application of a near infrared protease-specific probe is disclosed. The system includes a protease-specific near infrared (NIRF) imaging probe, means for topically administering the protease-specific probe to a diseased tissue and an imaging device capable of detecting the interaction between the protease-specific NIRF imaging probe and the diseased tissue. A method and surgical procedure are also disclosed.

Abstract: A composition for treating a disorder in a subject includes a polyethylene glycolylated (PEGylated) nanoparticle, at least one hydrophobic therapeutic agent coupled to the surface of the nanoparticle; and at least one targeting moiety coupled to polyethylene glycol of the nanoparticle for targeting the composition to a cell associated with disorder.

Abstract: A composition for treating a neoplastic disorder includes an activatable cell penetrating peptide coupled to antibody and/or fragment thereof to an essential gene product of a neoplastic cell.

Abstract: A composition for imaging a cell includes a first imaging probe and a second imaging probe that include respectively a first reporter moiety and a second reporter moiety. The first reporter moiety and the second reporter moiety form a signaling complex that produces a detectable signal when the first imaging probe and second imaging probe complex with first and second biomarkers of the cell.

Abstract: Described are methods for identifying targets in RNA molecules based on differences in RNA secondary structure related to sequence variances between different allelic forms. Also described are methods for identifying or developing small molecules which can be used to modulate a target RNA by creation of protein-small-molecule-RNA complexes, as well as compositions which include such small molecules and methods of using those small molecules and compositions.
