Cat. No. 6154
Chemical Name: (2S,4R)-1-((S)-2-(tert-butyl)-17-((
Biological ActivityCell penetrant Proteolysis Targeting Chimera (PROTAC) compound based on (+)-JQ1 (Cat.No. 4499), conjugated to a von Hippel-Lindau (VHL) ligand. Retains high affinity for BRD2, BRD3 and BRD4 bromodomains (Kd = 13-60 nM) but induces preferential degradation of BRD4 over BRD2 and BRD3 in cells at 10-100 nM concentrations. DC50 values for degradation of BRD4 are 8 and 23 nM in H661 and H838 cells, respectively. Replicates the effects of BRD4 protein removal by siRNA altering downstream gene expression patterns: downregulation of MYC and upregulation of genes such as P21 and AREG. No significant effect on HIF-α stabilization when used at low concentrations (<10 μM). Exhibits potent cytotoxicity and profound antiproliferative effects in AML cell lines such as Mv4;11 (pEC50 = 7.6), more potent and more effective than (+)-JQ1 (pEC50 = 6.5). Negative control cis MZ 1 also available.
PROTACs are bi-functional small molecules that harness the ubiquitin/proteasome system (UPS) to selectively and catalytically remove target proteins from cells.
