The present invention provides common ligand mimics that act as common ligands for a receptor family. The present invention also provides bi-ligands containing these common ligand mimics. Bi-ligands of the invention provide enhanced affinity and/or selectivity of ligand binding to a receptor or receptor family through the synergistic action of the common ligand mimic and specificity ligand which compose the bi-ligand. The present invention also provides combinatorial libraries containing the common ligand mimics and bi-ligands of the invention. Further, the present invention provides methods for manufacturing the common ligand mimics and bi-ligands of the invention and methods for assaying the combinatorial libraries of the invention.

The invention provides a method of identifying a population of bi-ligands to receptors in a receptor family. The method can include the steps of generating a first population of molecules comprising a specificity ligand having binding activity for a receptor in a receptor family, the specificity ligand attached to a first plurality of chemical moieties at a position on the specificity ligand to direct the specificity ligand to a specificity site and the chemical moieties to a conserved site of the receptor; screening the population of molecules for binding to the receptor; and identifying a bi-ligand having increased binding activity for the receptor relative to the specificity ligand alone, thereby identifying a common ligand having binding activity for the receptor. The method can further include the steps of generating a second population of molecules comprising the common ligand attached to a second plurality of chemical moieties.

resistance to the important β-lactam class of antibiotics. The OXA-48 and NDM-1 β-lactamases cause resistance to the last-resort β-lactams, carbapenems, leading to a serious public health threat. Here, we utilized DNA-encoded chemical library (DECL) technology to discover novel β-lactamase inhibitors. We exploited the β-lactamase enzyme–substrate binding interactions and created a DECL targeting the carboxylate-binding

We report here a class of thiazolidine-2,4-diones and 2-thioxothiazolidin-4-ones as potent inhibitors of the lymphoid specific tyrosine phosphatase (Lyp) identified from high throughput screens. Chemical modi. cation by incorporating the known phosphotyrosine (pTyr) mimics led to the discovery of a salicylate-based inhibitor with submicromolar potency. (c) 2008 Elsevier Ltd.
