Descrição

Aplicação

Enantioprobe (R)-2 is one of 16 fully functionalized, enantiomeric fragment probes developed in the Cravatt lab. Combining fragment-based ligand discovery (FBLD) with chemical proteomics, the enantioprobe library assesses ligandability across proteomes. Each enantioprobe contains a structurally variable fragment for interaction with proteins, photoactivatable diazirine for UV-induced covalent protein labeling, and bioorthogonal alkyne handle for detection, enrichment, and identification. Of the eight enantiomeric pairs, each differs by one stereocenter, and comparing stereoselective fragment-protein interactions between the pairs simplifies validation of authentic protein-binding events. Enantioprobe (R)-2′s paired fragment is available as Enantioprobe (S)-2 (cat# 913170).
Together, the 16 enantioprobes support ligandability studies in living cells, a significant method for development of chemical probes and lead discovery efforts to find binders for traditionally ″undruggable″ protein targets. This strategy is also compatible with multiplexing for higher throughput.
