butein

Butein is a cAMP-specific PDE inhibitor, protein tyrosine kinase inhibitor, and SIRT1 activator. It sensitizes HeLa cells to Cisplatin by targeting FoxO3a via the AKT and ERK/p38 MAPK pathways.

Coreopsin(Butein-4-O-β-D-glucopyranoside) is one of the main components from Coreopsis tinctoria Nutt. Flower(CTF). CTF has been used traditionally in China for treating hypertension and diabetes as well as reducing body weight and blood fat.

Butein tetramethyl ether (Compound 20) is a potent and selective inhibitor of breast cancer resistance protein / ATP-binding cassette sub-family G member 2 (BCRP/ABCG2). It inhibits MCF-7 MX and MDCKBCRP cells with IC50 values of 2.2 μM and 1.03 μM, respectively. Butein tetramethyl ether holds potential for cancer research.

4-O-Methylbutein (2',3,4'-trihydroxy-4-methoxychalcone) may have anti-inflammation activity, it is a potent heme oxygenase-1 (HO-1) inducer, the upregulation of HO-1 has proven to be a useful tool for fighting inflammation.

Homobutein (3-O-Methylbutein) is a dual inhibitor of HDACs and NF-κB with IC50s of 190 and 38 μM. Homobutein is an iron chelator with anticancer, anti-inflammatory, antiparasite, and antioxidation activities.
