Biguanide (/ b aɪ ˈ ɡ w ɒ n aɪ d /) is the organic compound with the formula HN(C(NH)NH 2) 2. It is a colorless solid that dissolves in water to give a highly basic solution. It is a colorless solid that dissolves in water to give a highly basic solution.
Polyhexanide (polyhexamethylene biguanide, PHMB) is a polymer used as a disinfectant and antiseptic. In dermatological use, [4] it is spelled polihexanide (INN) and sold under various brand names. [5] PHMB has been shown to be effective against Pseudomonas aeruginosa, Staphylococcus aureus, Escherichia coli, Candida albicans, Aspergillus ...
Bisbiguanide. Structure of chlorhexidine, a bisbiguanide antiseptic. Bisbiguanides are a class of chemically related compounds known for their bactericidal properties. Generally considered to be of the generic formula: R 1 R 2 N.C (:NR 6)NH.C (:NH)NH.CH 2 X-- (CH 2) 3 NH.C (:NH)NH.C (:NR 7)NR 3 R 4 V. [1] These compounds include the antiseptics ...
Metformin is a biguanide anti-hyperglycemic agent. [16] It works by decreasing glucose production in the liver , increasing the insulin sensitivity of body tissues, [ 16 ] and increasing GDF15 secretion, which reduces appetite and caloric intake.
Polyaminopropyl biguanide (PAPB) is a polymer containing biguanide group connected with a three methylene (propyl) linker. The polymer is a propyl analogue of polyhexamethylene biguanide. The polymer display some antibacterial activity however much lower than PHMB. [1] As of May 2024, PAPB is not approved as a biocidal active substance under EU ...
Acute toxicity describes the adverse effects of a substance that result either from a single exposure [1] or from multiple exposures in a short period of time (usually less than 24 hours). [ 2 ] To be described as acute toxicity, the adverse effects should occur within 14 days of the administration of the substance.
Toxicity is the degree to which a chemical substance or a particular mixture of substances can damage an organism. [1] Toxicity can refer to the effect on a whole organism, such as an animal, bacterium, or plant, as well as the effect on a substructure of the organism, such as a cell (cytotoxicity) or an organ such as the liver (hepatotoxicity).
Phenformin is an antidiabetic drug from the biguanide class. It was marketed as DBI by Ciba-Geigy, but was withdrawn from most markets in the late 1970s due to a high risk of lactic acidosis, which was fatal in 50% of cases. Phenformin was developed in 1957 by Ungar, Freedman and Seymour Shapiro, working for the U.S. Vitamin Corporation.
