Buformin hydrochloride has been used as an internal standard in liquid chromatography-tandem mass spectrometry to analyze postmortem distribution/redistribution of buformin in body fluids and solid tissues in an autopsy case.
生物化学的/生理学的作用
Buformin is an oral antidiabetic drug with antiproliferative properties; AMPK activator.
Buformin is an oral antidiabetic drug with antiproliferative properties; AMPK activator. Buformin, an antidiabetic biguanide drug, was withdrawn as an antidiabetic drug in several countries because of the side effect of lactic acidosis, but is now being investigated as an anticancer agent. Buformin inhibits the growth and development of cancer. Buformin has been shown to postpone spontaneous carcinogenesis as well as inhibit induced carcinogenesis in animal studies. Buformin decreased cancer incidence, multiplicity, and burden in a rat study of chemically induced mammary carcinogenesis. Buformin also reduced renal cell carcinoma survival under conditions of glucose deprivation. Buformin′s anticancer activity is thought to involve disruption of the Warburg effect by AMPK activation, which decreases hepatic glucose production, and inhibition of the mTor pathway.
An autopsy for a suicidal case of a male in his 40s, who had died of poisoning due to ingestion of a large amount of buformin, was performed at our department. Buformin is biganide class agent used for patients of
Buformin has been reported to be a powerful anticancer drug by activating the AMPK signal. Herein, we aimed to investigate the effects of buformin on osteosarcoma. Cellular proliferative abilities were determined by cell counting kit-8 and colony formation assays. Cellular
