Kinase patent space visualization using chemical replacements.
Here we present a methodology for characterizing the structure of patented chemical space. This approach identifies those chemical replacements that can connect sets of exemplified compounds in individual patents. Chemists can then search these replacements to help them discover the architecture within their patent space of interest. To demonstrate the utility of such an approach, we characterize a set of kinase inhibitors from patents and literature and find that many companies' patents can be understood to be straightforward modifications of competitors' patents. By reapplying these same chemical themes to other related compound series, novel, biologically active compounds can be discovered.
