Abstract
Protein kinases are implicated in diverse signaling cascades and have been targeted with small molecules that typically bind the conserved ATP-binding active site. These inhibitors are often promiscuous and target multiple protein kinases, which has led to the development of alternate strategies to discover selective ligands. We have recently described a fragment-based selection approach, where a small-molecule warhead can be non-covalently tethered to a phage-displayed library of cyclic peptides. This approach led to the conversion of the promiscuous kinase inhibitor, staurosporine, into a selective bivalent inhibitor.
