  • Publication number: 20200016114
    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.

  • Publication number: 20190275064
    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 date: July 11, 2019
    Inventors: William W. Bachovchin, Hung-sen Lai, Wengen Wu
  • 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.

  • Publication number: 20160250237
    Abstract: The invention provides compounds and methods for inhibiting proteases. One aspect of the invention features pro-soft inhibitors which react with an activating protease to release an active inhibitor moiety in proximity to a target protease. In certain instances, compounds inhibit proteasomes and/or post-proline cleaving enzymes (PPCE), such as dipeptidyl peptidase IV. The compounds of the invention provide a better therapeutic index, owing in part to reduced toxicity and/or improved specificity for the targeted protease.
