The present invention generally relates to sensitizer compounds and their use in combination with Tyrosine Kinase Inhibitors (TKIs) for sensitizing tumor, cancer or pre-cancerous cells to TKI treatment. In particular, the present invention relates to administration regimes that combine TKIs such as Gefitinib or Icotinib with TKI-sensitizing DZ1 esters and amides conjugated to statin or platin-based drugs, or to Artemisinin, including, without limitation: DZ1-Simvastatin amide, DZ1-Simvastatin ester, DZ1-Cisplatin ester, and DZ1-Cisplatin amide, DZ1-Artemisinin ester, and DZ1-Artemisinin amide. Furthermore, the present invention relates to improved TKI treatment of cancers by sensitizing tumor, cancer or pre-cancerous cells, in particular cancers that develop TKI resistance, including e.g. lung cancer and pancreatic cancer.

This application relates to dye-therapeutic moiety conjugates for imaging, targeting, and treating cancerous cells and/or tumors.

The present invention aims at providing a novel indocyanine compound solving problems of conventionally used indocyanine green, such as solubility in water or physiological saline, a synthesis method and a purification method thereof, and a diagnostic composition including the novel indocyanine compound. Further, provided are a method for evaluating biokinetics of the novel indocyanine compound and a device for measuring biokinetics, and a method and a device for visualizing circulation of fluid such as blood in a living body, which utilize the diagnostic composition. Also, found are a novel indocyanine compound in which a hydrophobic moiety in a near-infrared fluorescent indocyanine molecule is included in a cavity of a cyclic sugar chain cyclodextrin to cover the hydrophobic moiety in the indocyanine molecule with the glucose, and a synthesis method and a purification method thereof. Furthermore, found are a method for fluorescence-imaging an organ other than liver by intravenous administration, a method for evaluating biokinetics of the novel indocyanine compound, a device for measuring biokinetics, and a method and a device for visualizing circulation of fluid such as blood in a living body, utilizing the diagnostic composition including the novel indocyanine compound.

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 therapeutic-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 invention provides a novel class of cyanine dyes that are functionalized with sulfonic acid groups and a linker moiety that facilitates their conjugation to other species and substituent groups which increase the water-solubility, and optimize the optical properties of the dyes. Also provided are conjugates of the dyes, methods of using the dyes and their conjugates and kits including the dyes and their conjugates.

Sterile and non-toxic pharmaceutical compositions of near IR, closed chain, sulfo-cyanine dyes and methods for visualizing tissue under illumination with near-infrared radiation are provided.

The subject invention provides methods, assays, and products for detecting small molecules in a sample, in particular, in both clinical and field settings. The method for detecting a small-molecule target, preferably, a synthetic cathinone in a sample comprises contacting the sample with an aptamer-based sensor selective for the small-molecule target, and detecting the small-molecule target in the sample. Specifically, the method utilizes an aptamer-based sensor comprising a dye binding to a three-way junction binding domain of an aptamer. Binding of small-molecule target to the aptamer displaces the dye, generating a spectroscopic signal that can be used for detection of the small-molecule target and quantitative measurement of the target concentration.
