Beschreibung
Metformin is a biguanide with diverse biological activities. Metformin (250 mg/kg, i.p.) increases hepatic AMPK activity and reduces blood glucose by more than 50% in a liver kinase B1-dependent manner in mice fed normal and high-fat diets, respectively, and reduces blood glucose by 40% in
ob/ob mice. It reduces weight gain, hepatic lipid droplet content, and total cholesterol, LDL cholesterol, and triglyceride levels in the plasma of diet-induced obese mice when administered at doses of 10 or 50 mg/kg per day. It also reverses increased hepatic triglyceride and apolipoprotein A5 levels, as well as hepatic steatosis, in a dose-dependent manner in an
ob/ob mouse model of non-alcoholic fatty liver disease (NAFLD). Metformin (250 mg/kg) reduces tumor growth in an HCT116 p53
-\- human colon cancer mouse xenograft model, but has no effect on HCT116 p53
-\- tumors overexpressing recombinant
S. cerevisiae Ndi1 NADH dehydrogenase, a single-subunit ortholog of the multi-subunit mammalian mitochondrial complex I. Formulations containing metformin have been used in the treatment of type 2 diabetes.
Chemische Eigenschaften
Crystalline Solid
Verwenden
Metformin hydrochloride may be used as a pharmaceutical primary standard for the determination of the analyte in pharmaceutical formulations and human plasma samples by analytical techniques.
Definition
ChEBI: A hydrochloride resulting from the reaction of metformin with one molar equivalent of hydrogen chloride.
Allgemeine Beschreibung
1,1-Dimethylbiguanide hydrochloride (metformin) is a strong base. It forms well defined salts and possessing excellent coordination capacity with transition metals, forming highly colored bidentate chelate complexes. Metformin (MET) exists in various forms: diprotonated (H
2MET)
2+ in strong acidic solution, monoprotonated (HMET)
+ in weak acid, MET in neutral and deprotonated (MET)
- in strong alkali solution. It is an oral antidiabetic drug. Pharmacokinetics of metformin has been studied. Determination of metformin in human plasma has been described by simple HPLC-UV method. Metformin is reported to increase plasma active glucagon-like peptide-1 (GLP-1) in humans.
Biologische Aktivit?t
Antidiabetic agent; lowers plasma glucose levels and improves insulin sensitivity. Inhibits hepatic gluconeogenesis via activation of the LKB1/AMPK pathway. Displays antiproliferative effects in cancer cell lines.
