The term "biguanidine" often refers specifically to a class of drugs that function as oral antihyperglycemic drugs used for diabetes mellitus or prediabetes treatment. [4] Examples include: Metformin - widely used in treatment of diabetes mellitus type 2; Phenformin - withdrawn from the market in most countries due to toxic effects

A detailed crystallographic analysis of guanidine was elucidated 148 years after its first synthesis, despite the simplicity of the molecule. [6] In 2013, the positions of the hydrogen atoms and their displacement parameters were accurately determined using single-crystal neutron diffraction.
Like the pentose phosphate pathway, these pathways are related to parts of glycolysis. [3] Another carbon metabolism-related pathway involved in the generation of NADPH is the mitochondrial folate cycle, which uses principally serine as a source of one-carbon units to sustain nucleotide synthesis and redox homeostasis in mitochondria.
It is produced either in a de novo pathway from amino acids or in salvage pathways by recycling preformed components such as nicotinamide back to NAD +. Although most tissues synthesize NAD + by the salvage pathway in mammals, much more de novo synthesis occurs in the liver from tryptophan, and in the kidney and macrophages from nicotinic acid ...
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.
Alternatively, drugs blocking FAD synthesis could achieve the same goal; this is especially intriguing because human and bacterial FAD synthesis relies on very different enzymes, meaning that a drug made to target bacterial FAD synthase would be unlikely to interfere with the human FAD synthase enzymes.
Since the condensation of tryptamine and secologanin is the first committed step in alkaloid synthesis, strictosidine synthase plays a fundamental role for the great majority of the indole-alkaloid pathways. [1] This enzyme belongs to the family of lyases, specifically amine lyases, which cleave carbon-nitrogen bonds.
