  • Publication number: 20160346401
    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.

  • 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.

  • Publication number: 20140018545
    Abstract: The present invention relates to inhibitors of post-proline cleaving enzymes, such as inhibitors of dipeptidyl peptidase IV, as well as pharmaceutical compositions thereof, and methods for using such inhibitors. In particular, the inhibitors of the present invention are improved over those in the prior art by selection of particular classes of sidechains in the P1 and/or P2 position of the inhibitor that contain a carboxylic acid moiety. The compounds of the present invention can have a better therapeutic index, owing in part to reduced toxicity and/or improved specificity for the targeted protease.
