Patent number: 11168321Abstract: The present invention features a number of methods for identifying one or more compounds that bind to a biological target. The methods include synthesizing a library of compounds, wherein the compounds contain a functional moiety having one or more diversity positions. The functional moiety of the compounds is operatively linked to an initiator oligonucleotide that identifies the structure of the functional moiety.Type: GrantFiled: May 5, 2016Date of Patent: November 9, 2021Assignee: X-Chem, Inc.Inventor: Richard W. Wagner

Publication number: 20180002688Abstract: The present invention relates to methods for producing encoded chemical entities. In particular, the oligonucleotides and methods can include encoded chemical entities having wild-type linkages formed through chemical ligation techniques. One strategy that can be utilized that simultaneously takes advantage of chemical ligation as a means to encode chemical history, while also retaining the ability of polymerases to directly recover tag sequence and association information, is to perform chemical ligation in a manner that generates wildtype phosphodiester linkages. Such methods generally utilize condensing agents such as cyanogen bromide or similar along with 5?-phosphate and 3?-hydroxyl oligonucleotides in a double-stranded or templated context. Similarly cyanogen bromide has also been shown to chemically ligate pairs of substrate oligonucleotides that are 5?-hydroxyl and 3?-phosphate.Type: ApplicationFiled: December 28, 2015Publication date: January 4, 2018Applicant: X-Chem, Inc.Inventors: Anthony D. KEEFE, Alexander LITOVCHICK, Matthew CLARK, Richard W. WAGNER
