Use of Metformin

Metformin (1,1-Dimethylbiguanide) inhibits the mitochondrial respiratory chain in the liver, leading to activation of AMPK, enhancing insulin sensitivity for type 2 diabetes research. Metformin can cross the blood-brain barrier and triggers autophagy[1].

In Vitro	Metformin (1,1-Dimethylbiguanide) inhibits proliferation of ESCs in a concentration-dependent manner. The IC50 is 2.45 mM for A-ESCs and 7.87 mM for N-ESCs. Metformin shows pronounced effects on activation of AMPK signaling in A-ESCs from secretory phase than in cells from proliferative phase[3]. Metformin (0-500 μM) decreases glycogen synthesis in a dose-dependent manner with an IC50 value of 196.5 μM in cultured rat hepatocytes[4]. Metformin shows cell viability and cytotoxic effects on PC-3 cells with IC50 of 5 mM[5].
In Vivo	Metformin (1,1-Dimethylbiguanide; 100 mg/kg, p.o.) alone, and metformin (25, 50, 100 mg/kg) with isoproterenol groups attenuates myocyte necrosis through histopathological analysis[1]. Metformin (> 900 mg/kg/day, p.o.) results in moribundity/mortality and clinical signs of toxicity in Crl:CD(SD) rats[2].
