Tocris Bioscience™ XY-06-007

Description

XY-06-007 is a highly selective and potent Bump and Hole TAG Degrader (DC50,6h = 10 nM, T1/2 < 43.2 min). XY-06-007 comprises a cereblon (CRBN) E3 ligase ligand joined by a linker to a (+)-JQ1 (Cat. No. 4499) derivative (thebump bearer) that selectively binds the Brd4BD1 L94V variant (thehole). In cell lines expressing a fusion of the target protein with the tag, Brd4BD1 L94V, XY-06-007 drives formation of a ternary complex between CRBN and the tagged protein, leading to ubiquitination and subsequent proteasomal degradation of the entire protein. XY-06-007 is highly selective for Brd4BD1 L94V over wild-type, and is broadly selective across the proteome. XY-06-007 can be combined with the dTAG approach to achieve simultaneous degrader-mediated depletion of their respective protein fusions. XY-06-007 is suitable for in vivo studies.
