  • Patent number: 11925655
    Abstract: Disclosed are prodrugs of anthracyclines (such as doxorubicin) and derivatives thereof that are selectively cleaved and activated by fibroblast activating protein (FAP). The prodrugs are useful for targeted delivery of “warhead” anthracycline or anthracycline derivative to FAP-expressing tissues, including cancer (e.g., solid tumors). Also provided are pharmaceutical compounds comprising the prodrugs, as well as methods of using the prodrugs to treat a disorder characterized by FAP upregulation, e.g., cancer undesirable fibrosis and undesirable inflammation.

  • Publication number: 20230330275
    Abstract: The tumor stroma, which accounts for a large part of the tumor mass, represents an attractive target for the delivery of diagnostic and therapeutic compounds. Here, the focus is notably on a subpopulation of stromal cells, known as cancer-associated fibroblasts, which are present in more than 90% of epithelial carcinomas, including pancreatic, colon, and breast cancer. Cancer-associated fibroblasts feature high expression of FAP, which is not detectable in adult normal tissue but is associated with a poor prognosis in cancer patients. The present invention provides small-molecule radiopharmaceutical and imaging agents based on a FAP-specific inhibitor.
