NSC 150117 hydrochloride

(E/Z)-BCI hydrochloride has been used:

• to evaluate the role of the Duox-H₂O₂-Dusp6 derepression signaling pathway in heart regeneration
• as an MKP-1 inhibitor to investigate the role of MKP-1 on bexarotent-induced effects
• as a dual specificity phosphatase 6 (DUSP6) inhibitor to study its effects on the proliferation of SKOV3 cells

BCI is an allosteric inhibitor of Dusp6 that acts within the phosphatase domain to prevent the catalytic stimulation of phosphatase activity induced by ERK2 substrate binding. BCI also hyperactivates FGF signaling, since Dusp6 functions as a feedback regulator of FGF signaling.
