Infrared dyes having an infrared absorption maximum above 1130 nm with minor colouration in the visual spectrum. The infrared dyes are especially useful for producing multicolour laser marked security documents having reduced background coloration and enhanced colour gamut.

Compounds used as labels with properties comparable to known fluorescent compounds. The compounds can be conjugated to proteins and nucleic acids for biological imaging and analysis. Synthesis of the compounds, formation and use of the conjugated compounds, and specific non-limiting examples of each are provided.

The present invention provides for heptamethine cyanine dyes that possess both nuclear and near-infrared imaging capabilities. These dyes can be used for imaging, targeting and detecting tumors in patients.

The invention relates to a family of dyes which fluoresce in the UV-VIS, far red and near infrared wavelengths of the spectrum and possess asymmetric lipophilic alkyl chains. The dyes of the invention are soluble in commercially available membrane staining vehicles, are useful as probes for rapidly staining lipophilic structures such as membranes in cells or isolated from cells, and are well-retained therein. Methods of utilizing the dyes to detect stained cells both in vivo and in vitro are also disclosed.

pH-sensitive fluorescent compounds that can generate a detectable signal for the relatively small changes in proton concentration associated with cancerous tissue are described. Methods of making and using the compounds to help detect cancerous tissue are also disclosed.

The present invention generally relates to sensitizer compounds and their use to sensitize cancer and/or pre-cancerous cells of certain cancers to treatment with certain resistance-prone therapeutics used in cancer therapy. In embodiments, the conjugates of particular esters or amides of Near Infrared Dyes, are used as sensitizers to avoid or overcome therapeutic resistance once formed. In embodiments, the sensitizers include conjugates with Cisplatin, Simvastatin, Artemisinin, platin-based compounds or statins. In embodiments, the resistance prone cancer therapeutics include cisplatin, gemcitabine, doxorubicin, paclitaxel, docetaxel, and platin-based compounds. These may be administered in combination with the sensitizer, or the sensitizer itself may comprise an therapeutci-derived moiety conjugated to the sensitizer, for example as is the case for dye-CIS conjugated sensitizers. Alternatively, the sensitizer may be co-administered with one or more therapeutic. Embodiments of the invention may advantageously be used in cancers that have a tendency to develop resistance to such cancer therapeutics and/or to form metastases, including e.g. lung, pancreatic, prostate, testicular, ovarian, cervical, bladder, breast, head and neck, esophageal, and stomach, cancers, germ cell tumors, lymphomas and other cancers.

The application provides fluorescent dyes, which are cyanine dyes that incorporate additional aza moieties in the indolenium heterocycles and/or in the methine chains connecting them. Symmetrical and unsymmetrical chemically reactive azacyanine dyes are described for conjugation, as well as their bioconjugates for in-vitro and in-vivo assays and fluorescence imaging.

Glucose-sensing luminescent dyes, polymers, and sensors are provided. Additionally, systems including the sensors and methods of using these sensors and systems are provided.
