Other oral biguanides

such as metformin in the prophylaxis (prevention) and/or therapy of
In the early 1970s, Professor Vladimir Dilman originally developed the idea that antidiabetic biguanides
may be promising as geroprotectors and anticancer drugs ("metabolic rehabilitation").
Other classes of glucose-lowering drugs include sulfonylureas, meglitinides, biguanides
, alpha-glucosidase inhibitors and dipeptyidyl peptidase-4 inhibitors.
Of the biguanides
, metformin is the most commonly used, and is considered to work by inhibiting gluconeogenesis and increasing insulin sensitivity.
only prescribed drug was metformin.
Drugs which increase peripheral utilisation, called Biguanides
, are the preferred drugs to start with.
The first evidence of the potential antineoplasic utility of biguanides
was reported by Dilman and Anisimov in 1979 when they demonstrated that phenformin potentiated the antitumor effect of cyclophosphamide on transplantable squamous cell cervical carcinoma, hepatoma-22a and Lewis lung tumors (1).
Although the exact mechanism for causing lactic acidosis is not understood, it is postulated that biguanides
induce it by inhibiting certain microsomal enzymes involved in glucose metabolism (3).
One study revealed that biguanides
, phenformin and metformin were associated with embryo death, although metformin was observed to be less toxic than phenformin in mouse whole embryo culture (8).
work by: 1) inhibiting the normal hepatic glucose output 2) interfering with intestinal absorption of glucose from ingested carbohydrates, and 3) increasing peripheral glucose uptake.
