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 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.
