  • Patent number: 9522881
    Abstract: Inhibitors of protein tyrosine phosphatases are disclosed. The inhibitors include hydroxyindole carboxylic acids having a linker and an amine scaffold that are potent inhibitors of Src homology 2-domain containing protein tyrosine phosphatase-2.
    Type: Grant
    Filed: April 25, 2014
    Date of Patent: December 20, 2016
    Assignee: Indiana University Research and Technology Corporation
    Inventors: Zhong-Yin Zhang, Li-Fan Zeng
  • Patent number: 9493436
    Abstract: A variety of benzofurans and indole derivatives some with an alkynyl linker are disclosed herein. These compounds are not highly charged at physiological pH and have good bioavailability characteristics. These compounds exhibit selective or at least preferential affinity for the active sites of various sub-sets of protein tyrosine phosphatases. Some of these compounds are excellent inhibitors of Mycobacterium protein tyrosine phosphatase B (mPTPB) a protein tyrosine phosphatase expressed in Mycobacterium tuberculosis and characterized as a virulence factor in the causal agent of tuberculosis. Accordingly, many of these compounds and pharmaceutically acceptable salts thereof are useful for the treatment of diseases such as tuberculosis.
