Koen Augustyns 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: 11638712
    Abstract: The present invention relates to compounds for use in the prevention and/or treatment of PAR-related diseases, such as for example: pain and ocular disorders. More in particular, the present invention provides bis(acetamidophenyl) guanidinophenylethylphosphonates for use in the prevention and/or treatment of pancreatitis-related pain, IBS (irritable bowel syndrome), IBD (inflammatory bowel disease), dry eye disease and conjunctivitis sicca. These inhibitors were found to have a different inhibitory profile compared to diphenyl guanidinophenylethylphosphonates leading to a more pronounced effect on these conditions.

  • Patent number: 10017527
    Abstract: The present invention relates to novel compounds and probes which have a common chemical structure necessary to obtain potent inhibitory activity against KLK4 and/or may be used for the detection of KLK4 peptides and their activity. It further relates to the use of these compounds and methods for inhibiting and/or detecting KLK4 activity in vitro and in vivo by making use of said probes or inhibitors. The compounds of the invention differ from prior art compounds at least in the presence of phenyl guanidine (instead of e.g. benzyl guanidine) and/or the presence of a heteroatom in the tail group, their combined presence unexpectedly leading to potent and selective KLK4 inhibitory activity.
