Near infrared and shortwave infrared dyes can have polymethine structures.

The invention provides agents that target carbonic anhydrase, which can be used as imaging agents or therapeutic agents. The agents can be used to image tumor hypoxia as well as other physiological processes in a subject.

The present invention relates to compositions for and methods of optically imaging tissues or cells using imaging agents having desirable in vivo properties that result in improved signal-to-background ratio.

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

The purpose of the present invention is to provide a photosensitive composition having excellent curability even when a colorant or other substance for attenuating or blocking radiated light is present at a high concentration, the film thickness thereof is large, and the light source is visible-to-infrared light, particularly infrared light having low energy. The present invention is a photosensitive composition characterized by containing as essential components (A) an onium salt represented by general formula (1), (B) a sensitizer, and (C) a radical polymerizable compound. (In formula (1), Rf each independently represents a C1-8 alkyl group, a C2-8 alkenyl group, or a C6-10 aryl group, 80% or more of hydrogen atoms bonded to the carbon atoms of each group being substituted with fluorine atoms, n represents an integer of 1 to 5, and A.sup.+ represents a monovalent onium cation.)

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.
