Wengen Wu has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Publication number: 20140018359
    Abstract: Disclosed are 6-(morpholinoalkyl)-substituted pyridines, and pharmaceutically acceptable salts and prodrugs thereof, that are active against a range of mammalian therapeutic indications.
    Type: Application
    Filed: May 1, 2013
    Publication date: January 16, 2014
    Applicants: Arisaph Pharmaceuticals
    Inventors: William W. Bachovchin, Hung-sen Lai, Daniel Philip O'Connell, Wengen Wu, Christopher P. Kiritsy
  • 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.

  • Patent number: 8563533
    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.
    Type: Grant
    Filed: September 14, 2012
    Date of Patent: October 22, 2013
    Assignee: Trustees of Tufts College

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. Another aspect of the invention provides for the use of the disclosed compounds for treating Type II diabetes, insulin resistance, glucose intolerance, hyperglycemia, hypoglycemia, hyperinsulinemia, obesity, hyperlipidemia, or hyperlipoproteinemia.
