생물학적 활성
설명
KRIBB11 abolishes the heat shock-induced luciferase activity with an IC50 of 1.2 μM. It is an inhibitor of the transcription factor Heat Shock Factor 1 (HSF1). This compound induces growth arrest and apoptosis.
표적
HSF1 (Cell-based assay)
1.2 μM
시험관 내(In vitro)
KRIBB11 inhibits HSF1 activity in a concentration-dependent manner. It down-regulates HSP70 and HSP27. This compound can inhibit cancer cell proliferation, arrests the cell cycle at G2/M phase and induces apoptosis. But it does not inhibit heat shock-induced recruitment of HSF1 to the hsp70 promoter or phosphorylation of HSF1 Ser-230. This chemical inhibits heat shock-induced recruitment of pTEFb to the hsp70 promoter and p-TEFb-dependent Phosphorylation of polⅡ CTD Ser-2.
생체 내(In Vivo)
Using a mouse xenograft model, KRIBB11 treatment decreases tumor volume by 47% compared with untreated control mice. In addition, HSP70 protein levels are significantly decreased in tumors from mice treated with this compound, supporting the notion that it exerts its in vivo antitumor activity through HSF1 inhibition.
HCT-116 cells are treated with KRIBB11 at various concentrations for 48 h. Cells are then harvested by trypsinization, fixed with 70% chilled ethanol, and preserved at −20 °C before FACS analysis. Fixed cells are washed twice with phosphate-buffered saline (PBS) solution before being suspended in 500 μl of PBS and treated with 100 mg/ml RNase A at 37 °C for 30 min. Propidium iodide is then added to a final concentration of 50 mg/ml for DNA staining, and 20,000 fixed cells are analyzed on a FACSCalibur system. Cell cycle distribution is analyzed using the ModFit program.
