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
Biological ActivityAT 1 is a 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.

We tested the effect of AT1 PROTAC in degrading the endogenous BRD4 protein in glioblastoma cell lines with varying concentrations of AT1 starting from 100nM, 300nM and 1 uM.
