Spectrophotometric (UV) investigation on biguanide and substituted biguanides
Tetrahedron, 1972Abstract Biguanide base and its monosalts have absorption maxima at 230 mμ which has been attributed to π-π* transition. The spectral effect on replacement of a carbon π centre by a heteroatom nitrogen centre is discussed and attempt has been made to predict the spectral shifts in biguanide base and normal salts due to the substitution heteronitrogen

1996
The use of biguanides as oral antidiabetic agents has elicited considerable problems due to their lack of sufficient tolerability. The first derivative, phenylethylbiguanide (phenformin), was given marketing approval in the United States in 1957. Due to the serious side effects, however, the compound was withdrawn from the market in the United States ...

Specific Inhibition of Gluconeogenesis by Biguanides [PDF]
Nature, 1967 POSSIBLE schemes for the mechanism of the hypoglycaemic action of biguanides have raised considerable controversy in recent years. The possibility that these drugs may act through inhibition of oxidative phosphorylation, which may increase the glucose uptake of peripheral tissues1, has been frequently emphasized2–5, but experiments on the kinetics of ...

A direct access to heptasubstituted biguanides
Molecular Diversity, 2015An efficient and experimentally simple copper-catalyzed carbon-nitrogen bond formation for the synthesis of [Formula: see text]-arylated biguanides starting from aryl halides, carbodiimides, and 1,1,3,3-tetramethylguanidine is reported. The potential diversity of this type of reaction, easily available starting materials, and commercially available low-

Metformin: a new oral biguanide
Clinical Therapeutics, 1996The biguanide metformin is an oral anti-hyperglycemic agent used in the treatment of patients with non-insulin-dependent diabetes mellitus (NIDDM). Metformin is an important addition to the drug therapy options available for those patients because it reduces blood glucose levels predominantly by decreasing hepatic glucose production and release and ...

Effect of biguanides and atromid on fibrinolysis
Journal of Atherosclerosis Research, 1967Summary The effects of phenformin, metformin, and Atromid on blood fibrinolytic activity, plasma fibrinogen, and serum cholesterol levels were compared in a study of 36 out-patients with occlusive vascular disease. Atromid was the least satisfactory fibrinolytic drug, having only a transient effect on the blood clot lysis time, though a more ...

Review of Biguanide (Metformin) Toxicity
Journal of Intensive Care Medicine, 2018In the 1920s, guanidine, the active component of Galega officinalis, was shown to lower glucose levels and used to synthesize several antidiabetic compounds. Metformin (1,1 dimethylbiguanide) is the most well-known and currently the only marketed biguanide in the United States, United Kingdom, Canada, and Australia for the treatment of non-insulin ...

Biguanid-induzierte Laktatazidose
1995Es gibt Angaben, das das Risiko einer Laktatazidose unter Metformintherapie bei 0,024-0,084 Fallen pro 1000 Patientenjahre lage. Das entspricht 1:11000 bis 1:40 000 der Metformin-behandelten Patienten pro Jahr. Die Mortalitat ist nochmal um den Faktor 3 geringer. Die beschriebenen Todesfalle traten bei Patienten mit Kontraindikationen fur Metformin auf.
