Champak Chatterjee 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).

  • Patent number: 10669306
    Abstract: Solid supports for use in solid-phase peptide synthesis (SPPS) are provided. The solid supports may include a resin and a protected linker coupled to the resin. The linker may be an N-mercaptoethoxyglycine, an N-mercaptopropoxyglycine, an N-mercaptobutoxyglycine, and/or another suitable linker. Kits for use in SPPS are also provided. The kits may include a solid support, a solution including a thiol or a selenol, one or more pluralities of protected amino acids, and/or a wash buffer. Methods of SPPS are also provided. The methods may include providing a solid support including a resin coupled to a protected linker.
    Type: Grant
    Filed: February 3, 2017
    Date of Patent: June 2, 2020
    Assignee: University of Washington
    Inventors: Champak Chatterjee, Patrick M. Shelton, Caroline E. Weller

  • Patent number: 7785825
    Abstract: Lantibiotics are synthesized on ribosomes as prepeptides and post-translationally modified to a mature form. These modifications include dehydrations and cyclizations. Compounds and related methods of generating compounds, modified by dehydration, cyclization, or dehydration and cyclization, are disclosed. The disclosure includes in vitro approaches to effecting dehydration and cyclization leading to production of biologically active compounds such as lantibiotics and variants thereof. Synthetic variants and methods including combinatorial approaches for generating diverse lantibiotics and other compounds are disclosed. The invention has broad potential for applications including food, agricultural, and medical industries.
