Abstract

Investigation within the pTyr-binding pocket of the STAT3 SH2 domain led us to develop a novel synthesis of two pTyr mimetics, l-tetrazolylmethylphenylalanine (l-Tmp) and l-O-malonyltyrosine (l-OMT), that were next incorporated in a high affinity ligand of STAT3 SH2 domain. Biological evaluation of peptidomimetics on STAT3 dimerization identified l-OMT as the first non-phosphorus pTyr mimetic so far reported against STAT3 SH2 domain, harboring an activity similar to that of the Pmp-containing reference peptidomimetic.

Incorporation into a high affinity ligand of the STAT3 SH2 domain identified l-OMT as the first non-phosphorus pTyr mimetic reported so far against the STAT3 SH2 domain.Figure optionsDownload full-size imageDownload as PowerPoint slide
