  • Patent number: 11033525
    Abstract: Disclosed are prodrugs of cytotoxic anthracyclines (such as doxorubicin) and other therapeutic agents that are selectively cleaved and activated by fibroblast activating protein (FAP). The prodrugs are useful for targeted delivery of cytotoxic and other agents 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, fibrosis, and inflammation.
    Type: Grant

  • Publication number: 20200323994
    Abstract: Disclosed are proteasome inhibitors, fibroblast activation protein (FAP)-activated prodrugs of proteasome inhibitors, and pharmaceutically acceptable salts of the inhibitors and prodrugs. Also disclosed are related pharmaceutical compositions, and methods of using the inhibitors and prodrugs and compositions thereof, for example, in treating cancer or other cell proliferative diseases. In vitro and in vivo methods of quantifying the expression of FAP in a biopsy sample and a mammal, respectively, are also disclosed.

  • Publication number: 20200297745
    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.

  • Patent number: 10245248
    Abstract: Disclosed are prodrugs of therapeutic or imaging agents, which prodrugs are selectively cleaved by fibroblast activating protein (FAP) to release the agents. Upon cleavage by FAP of the FAP substrate, the prodrug releases the agent in its active form or in a form that is readily metabolized to its active form. Pharmaceutical compositions comprising the prodrugs, as well as methods of using the prodrugs to treat a disorder characterized by FAP upregulation are also disclosed.
