China manufacturer Metformin hydrochloride/Metformin hcl CAS 1115-70-4

Description Metformin (hydrochloride) is an FDA approved first-line drug for the treatment of type 2 diabetes. Metformin decreases hepatic glucose production, mostly through a mild and transient inhibition of the mitochondrial respiratory-chain complex 1.

In Vitro Metformin 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 (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].
Cell Assay ESCs are plated in 96-well plates at a concentration of 1×103cells/well. After attachment, cells are treated with different doses of metformin/compound C for 0 min, 15 min, 1 h, and 24 h. MTT assays are performed as described previously. In brief, MTT (5 mg/mL) is added to the 96-well plates at a volume of 10 μL/well, and the plates are incubated for 4 h. The MTT reaction is terminated by removal of the culture medium containing MTT, and 100 μL DMSO per well are added and incubated at RT on a shaker for 10 min to ensure that the crystals had dissolved sufficiently. Absorbance values are measured at 595 nm. Cell proliferation (percentage of control) is calculated as follows: absorbance (experimental group)/absorbance (control group). Cell proliferation inhibition (percentage of control) is calculated as follows: 100%−cell proliferation (percentage of control). Each experiment is performed in duplicate and repeated six times to assess result consistency.
Animal Admin The animals are randomized into six groups consisting of six rats each. Rats in group 1 (control) receives a subcutaneous injection of physiological saline (0.5 mL) and are left untreated for the entire experimental period. Rats in group 2 receives an oral administration of metformin (100 mg/kg; twice daily) for 2 days and are subcutaneously injected with saline at an interval of 24 h for 2 consecutive days. Rats in group 3 (MI control) receives an oral administration of saline (twice daily) for 2 days and are sc injected with isoproterenol (100 mg/kg) daily for 2 consecutive days at an interval of 24 h. Rats in groups 4 to 6 are treated with metformin at 25, 50, and 100 mg/kg. Metformin is dissolved in saline and is gavaged at a volume of 0.25-0.5 mL twice a day at an interval of 12 h, started immediately before isoproterenol injection.
