  • Patent number: 10675364
    Abstract: The present disclosure encompasses embodiments of a novel near-infrared-emitting molecular fluorophore and probes incorporating said fluorophore advantageous for in vitro and in vivo research studies. The fluorophore is robust, photostable, and possesses functionalities for easy bioorthogonal conjugation (e.g., click chemistry, hydrazone formation, Diels Alder, Staudinger ligation, etc.). It is biocompatible and emits at 711 nm in aqueous conditions. These fluorophores may be used to fluorescently tag biological molecules or structures of interest, or used as optical reporters (i.e., activatable molecular probes, fluorescent dyes) for specific biomarkers/analytes as they can be switched from “off” to “on.” This fluorophore is useful for cellular assays and preclinical small animal imaging as the near-infrared emission is highly penetrating, and the photophysical properties are outstanding. As such, the properties of this class of fluorophores could easily be translated for use in clinical applications.

  • Patent number: 10675366
    Abstract: The present disclosure provides a positron emission tomography (PET)-detectable 1-((2-fluoro-6-[18F]fluorophenyl)sulfonyl)-4-((4-methoxyphenyl)sulfonyl)piperazine ([18F]DASA-23) probe that can selectively bind to the pyruvate kinase variant M2 (PKM2) found in cancer cells, such as of human glioma. Given the importance of PKM2 in the regulation of tumor metabolism, there is an on-going need to non-invasively measure its expression through the development of PKM2-specific radiopharmaceuticals. Precursors useful for the synthesis of the radiolabeled [18F]DASA-23-PKM2-specific probe and related compounds, and their methods of synthesis, are provided. Since the half-life of the 18F isotope is approximately 110 min, it is advantageous for a practitioner to attach the radionuclide to the precursor shortly before administration. Therefore, a precursor compound suitable for receiving the radionuclide and capable of specifically binding to the PKM2 variant can be provided.
