Description: (+)-JQ1 based PROTAC with selectivity for BRD4
Chemical Name: (2S,4R)-1-(2R)-2-Acetamido-3-[[6-[2-[(6S)-4-(4-chlorophenyl)-2,3,9-trimethyl-6H-thieno[3,2-f][1,2,4]triazolo[4,3-a][1,4]diazepin-6-yl]acetamido]hexyl]thio]-3-methylbutanoyl]-4-hydroxy-N-[4-(4-methylthiazol-5-yl)benzyl)pyrrolidinine-2-carboxamide
Purity: ≥98% (HPLC)

Biological Activity

Cell penetrant Proteolysis Targeting Chimera (PROTAC) compound based on (+)-JQ1 (Cat.No. 4499) conjugated to a von Hippel-Lindau (VHL) ligand. Rationally designed based on a ternary complex crystal structure to improve selectivity for BRD4 degradation compared to MZ1 (Cat.No. 6154). Demonstrates profound and selective degradation of BRD4 in cells at 1-3 μM, with negligible loss of BRD2 and BRD3.

PROTACs are bi-functional small molecules that harness the ubiquitin/proteasome system (UPS) to selectively and catalytically remove target proteins from cells.
