Description

Buformin hydrochloride (1-Butylbiguanide hydrochloride) is a potent and orally active biguanide antidiabetic agent, an AMPK activator. Buformin hydrochloride decreases hepatic gluconeogenesis and lowers blood glucose production in vivo. Buformin hydrochloride also has anti-cancer activities and is applied in cancer study (such as, cervical cancer and breast cancer, et al)[1].

In Vitro

Buformin hydrochloride (0-10 mM; 5 days) inhibits SKBR3 and BT474 cells growth as a concentration-dependent manner, exhibits IC50 values of 246.7 μM and  98.6 μM for erbB-2-overexpressing SKBR3 and BT474 cells, respectively[1].
Buformin hydrochloride (0-3 mM; 48 hours)  increases the percentage of cells in G0/G1 phase and reduced the percentage of cells in S phase, especially in the SKBR3 cells[1].
Buformin hydrochloride (0-3 mM; 24 hours) suppresses RTK activation, including erbB-2 and IGF1R signaling  downstream, and Akt activation/phosphorylation is inhibited in both SKBR3 and BT474 cells[1].

Cell Viability Assay[1]

Cell Line: ErbB-2-overexpressing SKBR3 and BT474 cells
Concentration: 0 μM, 1 μM, 3 μM, 10 μM, 30 μM, 100 μM, 300 μM, 1, 3, or 10 mM
Incubation Time: 5 days
Result: Reduced cell viability in erbB-2-overexpressing breast cells.

Cell Cycle Analysis[1]

Cell Line: ErbB-2-overexpressing SKBR3 and BT474 cells
Concentration: 0.5 mM; 1 mM; 3 mM
Incubation Time: 48 hours
Result: Increased cells arresting in G0/G1 phase.

Western Blot Analysis[1]

Cell Line: ErbB-2-overexpressing SKBR3 and BT474 cells
Concentration: 0 mM, 0.1 mM, 0.3 mM, 1 mM, or 3 mM
Incubation Time: 24 hours
Result: Decreased p-AMPK, p-p706S, p-ERK1/2 expression in a concentration-dependent manner.
In Vivo

Buformin hydrochloride (oral administation; 7.6 mmol/kg of chow; 7 days) exhibits significantly reduced tumor volumes and weights, and hinders mammary morphogenesis and proliferation in MMTV-erbB-2 transgenic mice[1].

Animal Model: Female MMTV-erbB-2 transgenic mice[1]
Dosage: 7.6 mmol/kg
Administration: Oral administation; 7 days
Result: Inhibited mammary syngeneic tumor growth in MMTV-erbB-2 transgenic mice.
