Description
BCI is an allosteric inhibitor of dual-specificity phosphatases (DUSP). BCI treatment of DUSP6-Myc-transfected cells suppresses DUSP6 or DUSP1 activity. BCI induces expansion of myocardial progenitors that ultimately increases heart size in zebrafish embryos via inhibiting DUSP6. BCI also inhibits lung cancer and uveal melanoma cells viability (IC50 = 0.1 to 90 µM). DUSP6 functions a feedback regulator of fibroblast growth factor (FGF) signaling to limit the activity of extracellular signal-regulated kinases (ERKs) 1 and 2
