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.

Programmed Cell Death

Programmed Cell Death Poster

There are two currently recognized forms of programmed cell death: apoptosis and necroptosis. This poster summarizes the signaling pathways involved in apoptosis, necroptosis and cell survival following death receptor activation, and highlights the influence of the molecular switch, cFLIP, on cell fate.
