Crispene E (0-100 μM; 24 h) selectively reduces the viability of STAT3-dependent MDA-MB-231 breast cancer cells, with an IC50 of 5.35 μM at 24 h, whereas it exhibits much lower activity against STAT3-deficient A4 cells[1].
Crispene E (100 μM; 24 h) downregulates the mRNA expression of STAT3 and its target genes bcl-2, cyclin D1 and fascin in STAT3-dependent MDA-MB-231 breast cancer cells[1].
Crispene E (5 μM; 24 h) selectively downregulates the protein levels of pSTAT3 and fascin in serum-starved, IL-6-treated MDA-MB-231 breast cancer cells, with no effect on pSTAT1[1].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
