Product Information
Description: Butein is a cAMP-specific PDE inhibitor with an IC50 of 10.4 μM for PDE4. Butein is a specific protein tyrosine kinase inhibitor with IC50s of 16 and 65 μM for EGFR and p60c-src in HepG2 cells. Butein sensitizes HeLa cells to Cisplatin through AKT and ERK/p38 MAPK pathways by targeting FoxO3a. Butein is a SIRT1 activator.
   
Stability and Solubility Advice: Information concerning product stability, particularly in solution, has rarely been reported and in most cases we can only offer a general guide.
We recommend that stock solutions, once prepared, are stored aliquoted in tightly sealed vials and used within 1 month. Avoid repeated freeze and thaw cycles. Storage conditions for some special products should refer to their storage details.
