Butein potently inhibits cAMP-specific phosphodiesterase (type IV) activity with an IC
50
of 10.4±0.4 μM. In contrast, phosphodiesterase I, III and V activities were inhibited by Butein above 100 μM.
Butein, a plant polyphenol, is a specific protein tyrosine kinase inhibitor. Butein inhibits not only the EGF-stimulated auto-phosphotyrosine level of EGFR in HepG2 cells but also tyrosine-specific protein kinase activities of EGFR (IC
50
=16 μM) and p60
c-src
(IC
50
=65 μM) in vitro.
Butein (10, 20, and 40 μM; 24, 48, and 72 hours) inhibits cell growth in a dose- and time-dependent manner.
Butein exhibits anticancer activity through the inhibition of the activation of PKB/AKT and MAPK pathways, which are two pathways known to be involved in resistance to cisplatin. Butein (20 µM) decreases phosphorylation of AKT, ERK and p38 following 24 h of co-treatment with Cisplatin (20 µM).
Cell Viability Assay
| Cell Line: | HeLa cells |
| Concentration: | 10, 20, and 40 μM |
| Incubation Time: | 24, 48, and 72 hours |
| Result: | Inhibited cell growth in a dose- and time-dependent manner. |
Western Blot Analysis
| Cell Line: | HeLa cells |
| Concentration: | 20 µM |
| Incubation Time: | 24 hours |
| Result: | Decreased phosphorylation of AKT, ERK and p38 co-treatment with Cisplatin (20 µM). |
Butein (2 mg/kg every 2 days) in combination with Cisplatin (2 mg/kg every 2 days) for 3 weeks suppresses tumor growth in vivo.
| Animal Model: | Nude mice (12 female 6- or 7-week old) with subcutaneous tumor xenografts |
| Dosage: | 2 mg/kg |
| Administration: | Intraperitoneally; every 2 days; for 3 weeks |
| Result: | Enhanced the antitumor effects of Cisplatin in vivo. |
